Description

A CONNECTING DEVICE FOR TRANSMITTING ELECTRIC ENERGY, AN ARRANGEMENT AND A METHOD FOR MOVING THE DEVICE

FIELD OF THE INVENTION

The present invention is related to a moving arrangement according to the preamble of claim 1 , a method according to the preamble of claim 24, and a connecting device according to the preamble of claim 29. The invention is especially related to a device for connecting the diverter to a conductor for high voltage. The term high voltage is related to voltages larger than 1 kV.

PRIOR ART

It is known to divert currents caused by over-voltages from a high voltage conductor to earth via a diverter. Such a diverter is usually called surge diverter, but in the case where the diverter is applied to a power line, it is usually called line diverter. Such over-voltages may arise as a consequence of, for example, a stroke of lightning. Diverters are applied to the conductor in order to counteract insulation faults on the conductor due to the over-voltages, for example a flash-over over the insulation of the conductor. A plurality of diverters are usually arranged spaced along a power line.

The diverter has a core of a material arranged in such a way that it does not conduct currents at the operating voltage of the power line, but conducts currents when the voltage over the conductor exceeds a predetermined limit value. The current is then conducted from the power line to earth via the connecting device, the diverter, and a conductor connected to earth. Said diverters usually have such a large weight that moving them to and from the conductor is difficult, and for many diverters close to impossible for the maintenance crew to execute without means of assistance.

According to prior art, the connecting device, usually called attachment clamp, is mounted to a conductor for high-voltage by an operator located in the close vicinity of the conductor. Due to the fact that the conductors are arranged at a relatively large distance from ground level, usually at least 4-5 metres, a line carriage displaceable along the conductor is required for the operator, and/or a lift device in the form of a crane or similar in order to execute the mounting operation. Such a mounting opera- tion is time consuming , especially where the conductor extends over a terrain, which is difficult to access, and therefore economically disadvantageous. A further problem during the mounting operation of a connecting device according to prior art is that the conductor must be released from an applied voltage and earthed before the work can be executed , which is very expensive.

According to an example of a known connecting device, it has clamping means for obtaining a contact pressure sufficiently high for transmitting said currents between the conductor and the connecting device. The contact pressure is adjusted by manoeuvring a screw union, which is arranged in such a way that manoeuvring of the same requires that the operator is located in the close vicinity of the same.

The conductor must be released from the voltage both before the mounting operation of the connecting device and before any dismounting of the same from the conductor, which, for example, is needed when there is a breakdown of the same. SU MMARY OF THE INVENTION

A first objective of the present invention is to provide an arrangement for moving an object, by means of which it is possible to apply the object to a conductor for transmission of electric energy from a position distant from the conductor. The moving arrangement should further be easy to manoeuvre and create conditions for applying the object to the conductor without any heavier lifting operations for the operator.

This objective is achieved in that the arrangement comprises a support means for contacting the conductor, an elongated manoeuvring member connected to the support means and arranged for locating the support means on the conductor, and an elongated moving member, which is arranged for being supported by the support means and being connected to the object. The elongated moving member can be supported directly or indirectly by the support means. The elongated manoeuvring member preferably has the character of a substantially rigid element. Conditions are in this way created for an easy positioning of the support means on the conductor from a position distant from the conductor. Thus, the elongated manoeuvring member has the character of a bar or a rod.

The object may, for example, be formed by an electric apparatus, or a device for connecting such an electric apparatus to the conductor. The object is preferably formed by a device for connecting a diverter to the conductor.

According to an embodiment of the invention, the arrangement defines such a movement path for the object that it reaches a position in the vicinity of the conductor during the movement along the path, in which position a portion of the object, which portion upwards delimits an opening for receiving the conductor, is located above the conductor. In this way, the object is only required to be moved in the horizontal direction from said position in order to attach the object to the conductor. No further lifting operation is therefore required to attach the object to the conductor.

According to another embodiment of the invention, the arrange- ment comprises a member for a disengageable connection of the elongated moving member to the object. Preferably, the elongated moving member is rigidly connected to the connecting member, which is disengageably connected to the object. The connecting member preferably has a curved shape in order to at least partially surround the object. The connecting member preferably comprises a support portion, and the object is intended to rest against the support portion during the moving operation.

Both the elongated moving member and the elongated manoeu- vring member are formed by an electrically insulating material in order to enable an application of the object to the conductor while a voltage is applied to the conductor.

According to another preferred embodiment of the invention, the support means comprises two spaced support members for contacting the conductor and a frame connected to the support members. The elongated moving member is supported by the frame. A rigid support construction is in this way achieved for moving the object and attaching it to the conductor. The support means is preferably arranged in such a way that the support members are arranged on a sufficient distance from each other for attaching the object to the conductor between them. The frame is preferably arranged in such a way that it allows positioning of the object on a portion of the conductor between the support members when the support means contacts the conductor. The frame is at least partially arranged at such a distance from the conductor that a sufficient air gap is present between the conductor and the frame portion for attaching the object to the conductor at this frame position. A plurality of differ- ent frame shapes are possible for allowing such an attachment. According to a further development of the preceding embodiment, the moving member has the character of a flexible element. The moving member is further arranged in such a way on the frame that it is deflected around an axis extending in a direction different from the normal directions of the conductor when the support means contacts the conductor. Conditions are in this way created for moving the object in an easy way from a level substantially below the conductor, such as ground level, to the conductor, while the operator is located on the ground.

According to an alternative to the last-mentioned further development, the moving member is displaceably arranged along the manoeuvring member and the elongated moving member has the character of a substantially rigid element. Conditions are in this way created for applying the object in an easy way to the conductor from a position substantially on the same level as the conductor, such as from a power line tower, or a power line pole.

A second objective of the invention is to provide a method for moving an object, which method creates conditions for applying the object to a conductor for transmission of electric energy from a position distant from the conductor. The invention is further related to an easily performable method, in which heavier lifting operations are eliminated or at least reduced for the operator in relation to prior art.

This objective is achieved in that a support means is located on the conductor by means of an elongated manoeuvring member and that an elongated moving member connected to the object and supported by the support means is manoeuvred in such a way that the object is moved between said positions. The support means is preferably kept in its intended position on the conductor by means of said first, elongated manoeuvring mem- ber during the moving operation of the object. After the object has been moved to the conductor, a pressure means of the object is affected by means of an elongated effect member in such a way that the conductor is affected by the pressure means. This is executed in such a way that a suffi- ciently high contact pressure for transmitting said current is obtained between the conductor and an electrically conducting means of the object, which is electrically connected to the diverter.

A third objective of the present invention is to provide a device for connecting the conductor to a diverter, which device creates conditions for an easy application of the same to the conductor from a position distant from the conductor.

This objective is achieved in that the device comprises a body with a portion for receiving at least one part of the conductor, at least one electrically conducting means for being electrically connected to the diverter and being located in contact with the conductor, at least one pressure means, which is movably ar- ranged relative to the electrically conducting means for affecting the conductor in order to obtain a sufficiently high contact pressure between the conductor and the electrically conducting means for transmission of said currents, and means for attaching the body of the device to a moving arrangement, which com- prises at least one elongated manoeuvring member, by means of which an operator can apply the body to the conductor from a position distant from the conductor. Thus, the connecting device is especially arranged for applying the body to the conductor from a position distant from the conductor. The used term appli- cation is in this case related to both moving the connecting device to the conductor and attaching the connecting device to the conductor.

According to an embodiment of the invention, said attachment means comprises a first member for being engaged to a member of the moving arrangement in order to enable a movement of the device by means of the moving arrangement from a first position, in which the device is located substantially on the same level as, or below, the conductor, to a second position, in which the device is arranged at the conductor. Conditions are in this way created for an operator to move the device between said positions in an easy and stable way by means of said moving arrangement. The first engagement member is preferably shaped as a female part for receiving a male part of the manoeuvring arrangement.

According to another embodiment of the invention, the device comprises means for connecting the body to the diverter, and the connecting means is arranged on the body on a lower portion of the same. Thus, the connecting device is equipped for being mechanically connected to the diverter. The diverter is preferably arranged hanging underneath the body.

According to another embodiment of the invention, said attachment means comprises a second engagement member con- nected to the pressure means, by means of which the pressure means can be moved by the operator by means of the moving arrangement for obtaining said contact pressure. This results in that an operator is able to obtain the required contact pressure between the conductor and the electrically conducting means from a position distant from the conductor when the device is arranged on the conductor.

According to a further development of the preceding embodiment, the second engagement member is accessible for an op- erator in order to manoeuvre it via the moving arrangement, the operator being located on a level substantially below a level defined by the second engagement member when the body is arranged on the conductor. The second engagement member is preferably arranged at least partially below a lower portion of the body when the body is arranged on the conductor. The receiving portion forms at least a part of an upper portion of the body relative to an opening for insertion of the conductor, and the pressure means is moveably connected to a lower portion of the body relative to the opening . The connecting means is further arranged substantially below the receiving means on the lower portion of the body and the connecting means and the pressure means are arranged spaced along the lower portion. In other words, the connecting means and the pressure means are arranged at a distance from each other, preferably in the extension direction of the conductor, when the body is arranged on the conductor.

Further advantages with and preferable characteristics of the invention are described in the description below and in the other dependent claims.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

Figures 1 -4 illustrates a moving arrangement 30 according to a first preferred embodiment. The arrangement is arranged for applying an object 1 to a conductor 2, while a voltage is applied to the conductor, by an operator located in a position distant from the conductor, such as on the ground. The object is intended to be moved from a first position, usually on the ground, to a second position, in which it is applied to the conductor, which , for instance, is arranged 4-5 metres above the ground.

The arrangement is especially intended for applying the object 1 in the form of a device for connecting a line diverter 24 to the conductor 2.

The arrangement comprises a support means 3, which in turn comprises two spaced support members 4, 5, which contact the conductor 2, and a frame 6 connected to the support members 4, 5. The frame 6 comprises two legs 7, 8 and an arm 9, which connects the legs. A first leg 7 is connected to a first support member 4 and a second leg 8 is connected to the second support member 5. The arm 9 is arranged with a substantially straight angle relative to the legs 7, 8, and extends substantially parallel to the conductor 2, to which the support means is applied. An elongated moving member 10 is supported by the arm 9. The elongated moving member 10 is connected to the object 1 via a connecting member 1 1 . The arm 9 is arranged at a sufficient distance from the conductor 2 for allowing application of the object 1 to the conductor 2 between the legs 7, 8. The legs 7, 8 are arranged at a sufficiently large mutual distance for al- lowing application of the object 1 to the conductor 2 between the legs. The object 1 defines an attachment element, by means of which a diverter is electrically connected to the conductor 2. The object 1 itself does not need to be very heavy, but the part, for example the diverter, connected thereto may have a substantial weight, for example around 100 kgs.

The moving member 10 is deflected around a rotatable portion

12 of the frame. The rotatable portion 12 is formed by a roll member, which is mounted in bearings on the arm 9. The arm 9 is in this case formed by an axis, which is attached to the legs 7, 8. The roll member 12 is in turn formed by a disc-shaped member in the form of a pulley.

The elongated moving member 10 has the character of a flexible element and is formed by a cable or a wire. The elongated moving member 10 is preferably formed by a substantially electrically insulating material. This enables manoeuvring of the moving member 10 at a distance from the conductor 2, while a voltage is applied to the conductor.

The arrangement comprises an elongated manoeuvring member 13 for positioning the support means 3 on the conductor 2. The manoeuvring member 13 is connected to the support means 3, and the support means 3 is located on the conductor 2 by means of the manoeuvring member 13. The manoeuvring member 13 is suitably arranged with a sufficient length for making positioning of the support means 3 on the conductor 2 possible, while the manoeuvring member 13 is manoeuvred by an operator on the ground. The manoeuvring member 13 is preferably formed by an electrically insulating material. Positioning of the support means 3 on the conductor 2 is in this way possible, while a voltage is applied to the conductor. The manoeuvring member 13 is besides turnably connected to the support means 3. An application of the object to the conductor 2 is in this way made possible from a third position, in which an opening 14 of the object 1 intended for receiving the conductor 2 is at least partially located above the conductor, by a turning motion of the support means 3 executed by manoeuvring the manoeuvring member 13. This is illustrated in figures 3 and 4 and is de- scribed in more detail below.

The support means 3 comprises a member 15, which delimits the turning motion of the manoeuvring member 13 relative to the support means 3. The delimiting member 15 delimits the turning motion of the manoeuvring member 13 relative to the support means 3 in planes extending across the conductor 2. The de- limiting member 15 has an opening, through which the manoeuvring member 1 3 extends. A base portion 16 of the delimiting member 15 delimits the movement of the manoeuvring member 13 in one direction and the support member 5 delimits the movement of the manoeuvring member 13 in the other direction.

The elongated manoeuvring member 1 3 has the character of a substantially rigid element. The manoeuvring member may, of course, have a certain measure of flexibility. The term substan- tially rigid element relates to the fact that the manoeuvring member is at least not strongly flexible or foldable. The manoeuvring member may, for example, be formed by a bar or a rod.

The support members 4, 5 are arranged in order to at least partly surround the conductor 2. The support means 3 may in this way be relatively firmly arranged on the conductor 2, while the support means is supported via the manoeuvring member 13. The support members 4, 5 perferably have seats for receiv- ing the conductor 2. The support means 3 may be turned around the conductor 2 thanks to the fact that the support members 4, 5 are arranged to at least partly surround the conductor, said turning motion being executed by manoeuvring the manoeuvring member 13, while the support members 4, 5 contact the con- ductor 2.

The roll member 12 is in figure 1 located above the conductor 2. As a consequence of a suitable arrangement of the roll member 12 and the frame 6 relative to the connecting member 1 1 and the object 1 , the object 1 can be moved by means of the moving member 10 to the third position, in which the object opening 14 is at least partly located above the conductor 2. Thereafter, a movement of the object 1 is only required in the horizontal direction for applying it to the conductor 2. Such a movement is preferably executed in the way described above by means of a turning motion of the manoeuvring member 13 relative to the support means 3.

The connecting member 1 1 has a support portion, on which the object is intended to rest, and the support portion preferably has at least partially the shape of a hook in order to at least partly grip around the object 1 . The connecting member 1 1 preferably also comprises an engagement element 18 in order to engage with a correspondingly shaped element of the object 1 . The elongated moving member 10 is attached to the connecting member 1 1 via an attachment element 17. The attachment element 17 is formed by a plate, which is fixed to the body of the connecting member 1 1 by means of a screw union. The plate has a bent portion, which receives a portion of the moving mem- ber 10. A fixation of the moving member 10 relative to the connecting member 1 1 is achieved by fastening the screw union. The connecting member 1 1 comprises a fixing element 25 in order to further support the object 1 during the movement and the attachment, respectively. The object is in this way effectively obstructed from sliding off the moving member 1 1 during the moving operation and the attachment.

Figure 2 illustrates a front-view of the inventive arrangement according to the first preferred embodiment. The support members 4, 5 and the legs 7, 8 are arranged at a distance from each other, which is larger than the width of the opening 14 of the object 1 . A connection of the object 1 to the conductor 2 between the support members 4, 5 is in this way made possible. The opening of the object 1 extends over the width of the com- plete object. It is obvious from figure 2 that the object 1 can be located between the support members 4, 5 and the legs 7, 8, respectively. The arm 9 is besides arranged at a sufficient distance from the conductor 2 for a connection of the object 1 to the portion of the conductor 2 present between the support members 4, 5. Figure 3 illustrates a side-view of the inventive arrangement according to the first preferred embodiment. The arrangement is illustrated in a position corresponding to its position in figure 2. The roll member 12 is arranged at a sufficient distance from the conductor 2, in the example above the conductor 2, for positioning the object 1 in a third position, in which the opening 14 for receiving the conductor 2 is located on the same level as the conductor 2. The arrangement comprises means for delimiting the movement of the moving member 10 when the object 1 is brought to the third position. The delimiting function of the delimiting means is obtained in that the connecting member 1 1 rams into a portion of the frame 6 when the object 1 has reached the third position. This frame portion is formed by the roll member 12 in the preferred embodiment. A plurality of dif- ferent ways of achieving said delimiting means is however possible within the frame of the inventive claims. It is obvious from figure 2 that an upper portion 19 of the connecting member 111 and an upper portion 160 of the object 1 can pass the conductor 2 vertically when the object is moved by means of the moving member 10.

The support means 3 is positioned on the conductor 2 in a first operation with the aid of the manoeuvring member 13 when the object 1 is to be applied to the conductor. The moving member 10 is connected to a counterweight member 21 at a first end thereof. The counterweight member 21 is arranged in a position in the vicinity of the roll member 12 during the positioning of the support means 3 on the conductor 2, which position is shown in figure 1 . The movement of the object 21 relative to the frame 6 is delimited by an element 22. The delimiting element 22 is arranged sufficiently close to the roll member 12 in order to obstruct passage of the object 21 between them. The delimiting element 22 is formed by a bar fastened to the legs 7, 8. The counterweight member 21 is kept in the vicinity of the roll mem- ber 12 during positioning of the support means 3 on the con- ductor 2, preferably by applying a tensile force on the moving member 10. The moving member 10 is released when the support means 3 is positioned in a desired position on the conductor 2 so that the counterweight member 21 is displaced down- wards on a side of the conductor 2 opposite the manoeuvring member 1 3 under the influence of gravity. A tensile force is applied to the parts of the moving member 10 extending between the counterweight member 21 and the roll member 12 when the counterweight member 21 has been lowered to a level, on which it is accessible for an operator. The object 1 may in this way be pulled up from the first position, in which the object is located at a distance below the conductor, to the third position, in which the opening 14 for receiving the conductor 2 is at least partly located above the conductor or on the same level as the con- ductor. By turning the support means 3 around the conductor 2 with an angle α, see figure 4, by means of the manoeuvring member 13, a portion of the conductor 1 located between the support members 4, 5 is brought into the opening 14. The angle α is suitably about 30°. The delimiting member 15 of the support means 3 delimits the turning motion of the support means 3 around the conductor 2 due to the fact that the manoeuvring member 13 is brought into contact with the base portion 16 of the delimiting member 15 when the desired angle α is obtained. The object 1 is thereafter lowered relative to the conductor 2 by releasing the moving member 10 on a side of the conductor 2 opposite the manoeuvring member 13. The object 1 will be displaced substantially horizontally during the displacement between the third position and a fourth position, in which the conductor 2 is received in the opening 14.

According to another, not shown, embodiment of the inventive arrangement, the support members 4, 5 have the form of hooks. In this way, a position of the support means 3 at a level below the conductor 2 is made possible while the support means is kept on the conductor by means of the hook-shaped support members 4, 5. The roll member 12 is also arranged at a level below the conductor 2. The connecting member 1 1 is fastened to the moving member 10 in such a way that the object 1 can be moved upwards while its opening 14 is directed upwards. The object 1 is in this case supported by an element in the form of, for example, a step of the connecting member 1 1 . This step extends from the moving member 10 and outwards, preferably in the normal direction of the moving member 10. A bar 23, shown in figure 1 , is not required according to the second preferred embodiment. The support means 3 is positioned on the conduc- tor 2 by means of the manoeuvring member 1 3. Due to the fact that the roll member 12 is arranged below the conductor 2, the complete moving member 10 will be arranged below the conductor 2. Any counterweight member 21 , according to the first preferred embodiment, is not required.

The object 1 is pulled up towards the roll member 12 while the object opening 14 is directed upwards. The moving operation of the object 1 via the moving member 10 is not ended when the object reaches the roll member 12, but continues around the same, and the object opening is directed substantially horizon- tally when the object 1 reaches its highest position. The roll member 12 is in this case arranged at a distance from the conductor 2 sufficient for the conductor 2 to be received by the object opening 14 when the object has reached said highest position. The object 1 is therefore applied to the conductor 2 via a turning motion. The application takes place by moving the moving member 10 relative to the support means 3. The connecting member 1 1 is only arranged to support the object 1 during the movement and is thus not arranged to grip around the object 1 . The connecting element can be arranged in such a way that it is allowed to be moved between the roll member 12 and the conductor 2 during the displacement of the moving member 10 after the application of the object 1 to the conductor 2, and thereby be released from the object 1.

According to an alternative embodiment of the connecting mem- ber 1 1 , it comprises elements for engagement to the object 1 . The moving member 1 1 is in this case only displaced to a position, in which the object 1 is applied to the conductor 2. The connecting member 1 1 is thereafter brought out of engagement with the object 1 and is lowered back down from the roll member 12 on the same side as it was lifted on.

According to the description above, the object 1 is moved with the aid of the elongated moving member 10. According to the first preferred embodiment, the object 1 is moved indirectly by the moving member 10 during the movement between the third and the second position by manoeuvring the manoeuvring member 1 3.

According to the first preferred embodiment of the arrangement, the elongated manoeuvring member 13 is intended for locating the support means on the conductor 2, for keeping the support means 3 in a desired position during the lifting operation of the object 1 to the conductor 2, and for turning the support means 3 around the conductor 2 for connecting the object 1 to the conductor 2.

The arm 9 of the frame 6 is preferably rigid and is, formed, for example, by an axis. The frame 6 may, however, within the frame of the inventive claims have different shapes and it may, for example, comprise two legs, which are arranged obliquely towards each other. The frame may further have the form of an arc, for example extending along a half-circular path between the support members 4, 5.

The cross-section of the roll member 12 is substantially circular according to the first preferred embodiment of the arrangement. Further, the roll member 12 has a groove around its periphery for receiving the elongated moving member 10. The roll member may, however, within the scope of the inventive claims, be arranged in a plurality of different ways. The cross-section of the roll member 12 may, for example, be polygonal, formed by a chain wheel, etc. According to the first preferred embodiment, the elongated moving member 10 is formed by a cord or a wire with a substantially circular cross-section. The moving member 10 could however also have a polygonal cross-section , such as a rectangular cross-section. By arranging the roll member 12 with a shape corresponding to the cross-sectional shape of the moving member 10 in a suitable way, the same side of the moving member will face the conductor, at least in the vicinity of the conductor. This implies that the opening 14 of the object 1 will face the conductor 2 when the object is located in the vicinity of the conductor 2. No further control of the object 1 is in this way required before it is applied to the conductor 2. The moving member 10 may also be formed by a chain. The roll member 12 is in this case formed by a chain wheel. Said desired alignment of the object 1 in the vicinity of the conductor 2 is in this way achieved.

The arrangement may, as an alternative or a complement to said arrangement of the moving member 10 relative to the roll member 12, be provided with elements for controlling the connecting member 1 1 relative to the support means 3 and/or the conductor 2 during a movement of the moving member in order to bring the connecting member 1 1 to a position, in which the opening 14 of the object 1 , at least in the vicinity of the conductor, is directed towards the conductor. The control element may, for example, comprise a conical portion or controlling legs. The control ele- ment may be arranged on the connecting member 1 1 as well as on the support means 3.

It is also within the frame of the inventive claims that the support means 3 comprise an apparatus with a plurality of roll members. A gear mechanism may be obtained by a suitable ar- rangement of the roll members and the moving member 10, so that also very heavy objects may be displaced by an operator with the aid of the moving arrangement.

According to the above described embodiments of the arrangement, an operator should apply a tensile force to the moving member 10 at an end of the moving member located opposite the object 1 in order to lift the object to the conductor 2. It is, however, also possible to arrange a force exerting member in the form of, for example, an electric motor in order to obtain this displacement. Such a force exerting member may be arranged both in the first position, preferably on the ground, and on the support means 3.

The member 16 for delimiting the turning motion of the manoeuvring member 1 3 relative to the support means 3, also forms an aid for obstructing the support means 3 from falling over in any direction when it is located on the conductor 2.

Figure 5 illustrates a first preferred embodiment of the connecting device 1 in a perspective view, wherein the device is arranged on the conductor 2. The diverter 24 is movably con- nected to the device 1 at a lower portion 161 of the device. The diverter defines in this case a line diverter or a surge arrester.

The connecting device 1 is arranged for transmitting currents caused by over-voltages in the conductor 2 to the diverter 24, which has a conductor 27 connected to earth at an end 26 op- posite the device 1 .

The device 1 has a hook-shaped body 101 , which comprises a portion 106 for receiving the conductor 2. The receiving portion 106 forms an upper portion 160 of the body 101 and is arranged to rest on the conductor substantially from above. The currents caused by the over-voltages are intended to be transmitted from the conductor 2 to an electrically conducting means 107 of the device, which, according to the first preferred embodiment, is formed by the section of the receiving portion 106 located in contact with the conductor 2. The receiving portion 106 is formed by an electrically well conducting material, for instance, aluminium. The currents are intended to be conducted further through the device to the diverter 24. The device is provided with a pressure means 108, which is movably arranged relative to the electrically conducting means 107 and displaceable in the direction towards and from, respectively, the electrically conducting means 107 in order to subject the conductor 2 to a clamping force. In this way, a sufficiently high contact pressure between the conductor 2 and the electrically conducting means 107 is obtained for transmitting the currents.

The pressure means 108 comprises a pressure element 109 lo- cated at an end thereof facing the electrically conducting means 107, which pressure element 109 is intended to contact the conductor 2. According to the first preferred embodiment, the pressure element is formed by a collet jaw, which has a length extension along the length extension of the conductor 2 in order to obtain a suitably large contact surface between the conductor 2 and the electrically conducting means 107 for transmitting said currents. The term suitably large contact surface means that the current can be divided along the surface and conduction of the same is made possible substantially without any forming of burn-marks.

The hook-shaped body 101 has a support portion 1 10 connected to the receiving portion 106, at which the pressure means 108 is movably arranged. The pressure means 108 may, for example, be movably arranged through a hole running through the support portion 1 10. The support portion 1 10 is in this case formed by a lower portion 161 of the body. A second engagement member 1 1 1 is arranged at an end of the pressure means 108 opposite the pressure element 109, and the pressure means is arranged to be moved relative to the electrically conducting means 107 with the aid of the second engagement member. The engagement member 1 1 1 is arranged with a high degree of accessibility from below and/or from a position on substantially the same level as said member in order to be manoeuvred by an operator located distant from the conductor 2. Distant from the conductor 2 is in this case related to a distance of several metres. Ac- cording to the embodiment illustrated in figures 5-7, the operator is intended to be located on the ground below the conductor 2, which conductor may be arranged, for example, five metres above the ground. The operator could however also be located on a level above the ground during the manoeuvring operation, which level may substantially coincide with the level defined by the conductor and at a distance from the conductor of a few metres. The operator can in the last mentioned case either be located in a construction, in the form of a power line pole or a power line thorn, intended for keeping the conductor at said distance from the ground, or in a construction or a lifting apparatus for the desired application of the device to the conductor. The pressure means 108 is arranged to form a screw union together with the support portion 1 10 in order to obtain said con- tact pressure. The pressure means has a portion with an outer threading, a so-called thread-tap, and said hole running through the support portion 1 10 has a corresponding inner threading. These parts form said screw union. The engagement member 1 1 1 is arranged for transmitting a torque. The displacement of the pressure means 108 is therefore achieved by revolving the engagement member 1 1 1 . Said second engagement member 1 1 1 comprises a bolt run through by a transverse pin. A manoeuvring rod is arranged with a groove at a first end thereof in order to engage with this engagement member, said groove run- ning in the transverse direction of the rod and being open towards said end. The rod preferably has the shape of a tube. In other words, the engagement between the elongated manoeuvring member and the engagement member 1 1 1 is obtained by a bayonet catch.

The device 1 has an opening 14 and the conductor portion is intended to pass through the opening to a desired position, in which it is received by the receiving portion 106, via a moving operation of the device relative to the conductor. The portions 160, 161 , see figure 7, delimiting the opening 14 are arranged at a mutual distance substantially larger than the size of the con- ductor 2 in order to make an easy application of the device 1 to the conductor 2 possible.

The device 1 has a portion 1 13, which connects the receiving portion 106 and the support portion 1 10, see figure 7. According to the first preferred embodiment of the device, the connecting portion 1 13 is formed by a side-wall of the body 101 .

The device 1 has means 1 16 for connecting the body 101 to the diverter 24. The connecting means 1 16 is suitably arranged for making movement of the diverter 24 relative to the body 101 possible. According to the first preferred embodiment of the device, the connecting means 1 16 is formed by a link part. It is however also within the scope of the inventive claims that the connecting means 1 16 is formed by a hinge member, a flexible member, or similar.

An element 1 17 of a material, which is electrically well conducting, is galvanically connected to the body 101 and the diverter 24 in parallel with the connecting means 1 16 in order to reduce or eliminate conduction of said currents through the connecting means 1 16, which suitably is formed by a material with a high electric resistivity. The connecting means 1 16 would otherwise burn off during conduction of too large currents. The currents caused by over-voltages of the conductor 2 will therefore be transmitted from the conductor 2 to the electrically conducting means 107 through the body 101 of the device 1 and through the diverter 24 via the element 1 17 and from the lower end 26 of the diverter via the conductor 27 to earth.

Figure 6 illustrates the device according to figure 1 in a front view. The device 1 is arranged in such a way that it allows application of the body 101 to the conductor 1 by an operator lo- cated in a position distant from the conductor. Therefore, the device has means 1 1 1 , 1 18 for attaching the body to the earlier described moving arrangement 30. The term application is related to both hooking the body 101 onto the conductor and fas- tening the body to the conductor. The attachment means 1 1 1 comprises said second engagement member 1 1 1 , which is arranged well accessible from below. The second engagement member 1 1 1 is arranged below said lower portion 161 of the body 101 . The pressure means 108 is further mounted to the lower portion 161 in such a way that the pressure means is brought in direction towards and from, respectively, the upper portion 160 of the body 101 when the engagement member 1 1 1 is manoeuvred appropriately. Said movement is, for instance, a translational movement. The attaching means also comprises a first engagement member 1 18 for being brought into engagement with a member 18 of the manoeuvring arrangement 30 for executing a displacement of the device from a first position, in which the device is located, for example, on ground level, to a second position, in which the device is arranged on the conductor. The first engagement member 1 18 and the second engagement member 1 1 1 are arranged in a lower region of the device 1 and well accessible for an operator via the manoeuvring arrangement 30. According to the first embodiment of the de- vice, the first engagement member 1 18 forms part of the connection means 1 16.

Figure 7 illustrates the device 1 from figure 5 in a side-view. The receiving portion 106, which is formed by the upper portion 160 of the body 101 , has a bent shape, but may also within the frame of the inventive claims, for example, comprise two parts forming an angle to each other. The pressure element 9 has a valley or recess for receiving a lower section of said conductor portion. The recess makes a firm fixation of the device relative to the conductor possible and makes a high contact pressure between the electrically conducting means and the conductor possible. A fixation of the device at a specific position along the conductor 2 is obtained by bringing the pressure means 108 to affect the conductor in such a way that said contact pressure is obtained between the conductor and the electrically conducting means. According to the first preferred embodiment of the connecting device, the hook-shaped body 101 is one single piece. It is however also within the frame of the inventive claims that the body is formed by a plurality of parts, which are combined to an inte- grated structure.

Figure 8 illustrates an alternative location of the diverter 24 in relation to the connecting device 1 . The diverter is in this case arranged on a construction 28 in the form of a power line pole. The diverter 24 is electrically connected to the connecting de- vice 1 via an electrically conducting element 29. According to this embodiment, the diverter 24 does not load the connecting device 1 and the line 2 with its own weight. The difference between the embodiment of the connecting device illustrated in figures 5-7 and this embodiment of the connecting device is that the connecting device is not equipped with the connecting means 1 16. A lifting operation of the diverter 24 up to a level in the vicinity of the conductor 2 is in this case not required for the application of the connecting device 1 .

Figures 9-1 1 illustrate a manoeuvring arrangement 31 according to a second preferred embodiment. The manoeuvring arrangement 31 comprises a support means 40 for supporting the arrangement against the conductor 2. The support means 40 has a similar construction to the support means according to the first preferred embodiment of the manoeuvring arrangement 30. The support means 40 is rigidly connected to an elongated manoeuvring member 32. The legs 7, 8 of the support means 40 are inclined back towards the conductor in the longitudinal direction of the manoeuvring member 32 from their connection region to the same.

The elongated manoeuvring member 32 has the character of a substantially rigid element and is preferably formed by an electrically insulating material. An operator of the manoeuvring arrangement 31 is located approximately on the same level as the conductor 2 during the application of the connecting device 100. The operator is located on a platform 36 arranged on the power line pole 28 in the example illustrated in figure 9.

The manoeuvring arrangement 31 further comprises an elongated moving member 33, which is displaceably arranged along the bar 32 via a connecting member 41 . The elongated moving member 33 also has the character of a substantially rigid element and is preferably formed by a substantially electrically insulating material. Below, the elongated manoeuvring member 32 is called manoeuvring bar and the elongated moving member 33 is called moving bar.

The connecting member 41 is displaceably arranged along the manoeuvring bar 32 via a displacing member 42, which in this case is formed by a roll member contacting the bar 32 and rotatably arranged along the same.

The moving bar 33 has an engagement member 35, see figure 10, in the form of a threaded cylindrical tap on the end of the moving member 33, which is opposite the manoeuvring end. The engagement member 35 is intended to interact with a correspondingly shaped, first engagement member 1 19 in the form of a threaded hole in the body 102 of the connecting device 100. The engagement members 35 and 1 19 are intended to be engaged with each other during the movement of the connecting device 100. In this way, a secure holding of the connecting device 100 during the moving operation is achieved. The body 102 of the connecting device 100 is further arranged to rest with its lower portion 161 against a lower portion 181 of the connecting member 41 . The threaded hole 1 19 preferably extends through a side-wall 1 13 of the body 102. By means of this rigid connection of the moving bar 33 to the connecting device 100 during the movement, conditions are created for controlling the connecting device in such a way that the opening 14 of the body 102 faces the conductor. The moving bar is mounted in bearings in the connecting member 41 and extends through its body. Thus, the moving bar 33 is turnably connected to the connecting member 41 .

The roll member 42 has a groove 50, see figure 1 1 , running in its circumferential direction. The groove is arranged with a_. shape corresponding to the shape of the manoeuvring bar 32 and at least partly surrounds the manoeuvring bar. Conditions are in this way created for a stable displacement of the connecting member 41 and the connecting device 100 along the manoeuvring bar 32. The connecting device 41 comprises a leg 182 on each side of the intended position for the connecting device 100 on the lower portion 181 . The legs extend up from the lower portion 181 to the axis 51 of the roll member 42. The lower portion 181 of the connecting member 41 is provided with a groove, in which the link part 1 16 of the connecting device is intended to be received when the body 102 rests against the lower portion 181 .

The second manoeuvring arrangement 31 is, for example, preferable when the distance between the power line and the ground level is very large, such as >6 metres or when the ground surface is difficult to reach or in such a condition that it is difficult to work from.

The application of the connecting device 100 to the conductor 2 by the aid of the moving arrangement 31 takes place in the fol- lowing way:

The diverter 24, the connecting device 100 , and the moving arrangement 31 are lifted up to the platform 36 with the aid of a crane, sky-lift, or similar. The moving bar 33 is brought into engagement with the connecting device 100 via the engagement members 35, 1 19. The support means 40 is located on the conductor 2 with the aid of the manoeuvring bar 32. The connecting member 41 is thereafter displaced along the manoeuvring bar 32 with the aid of the moving bar 33 to a position, in which the con- necting device is in contact with the conductor. The moving bar 33 is thereafter brought out of engagement with the connecting device 100 and the connecting member 41 is moved back along the manoeuvring bar 32 to the platform 36. The manoeuvring bar 32 is lifted back to the platform 36. The connecting device may thereafter be moved to a desired position along the conductor and thereafter be fastened to the conductor with the aid of an elongated effect member 34, see figure 12, from the platform.

A second preferred embodiment of the connecting device 100 is illustrated in figures 10 and 1 1 . The body portion 106 for receiving the conductor 2 is in this case formed by a lower portion 161 of the body 102. The pressure means 108 is displaceably arranged at the upper portion 160 of the body 102. Thus, the conductor 2 will be located between the jaw 109 of the pressure means 108 and the lower portion 161 of the body 101 when the connecting device 100 is fastened to the conductor 2. The connecting device 100 comprises an engagement member 1 12 in the form of a screw with a hexagonal head, which is accessible from above. The manoeuvring arrangement 31 comprises an elongated effect member 34, see figure 12, for manoeuvring the engagement member 1 12. The effect member 34 is provided with an engagement member 54 on an end 53 opposite the manoeuvring end 52. The engagement member 54 has a shape corresponding to the shape of the engagement member 1 12 of the connecting device 100. The engagement member 54 of the effect member 34 is in this case formed by a ratchet spanner with a grip region fitting to the shape of the screw head 1 12. The effect member 34 may rest towards the screw head 1 12 during the fixation of the jaw 109 to the conductor 2 thanks to the fact that the screw head 1 12 is accessible from above. This results in the fact that operator will not be affected by the weight of the effect member 34 during the screwing operation. The engagement member 1 12 may, of course, be formed in a plurality of different ways, and may, for example, form a part of a bayo- net catch similar to the second engagement member 1 1 1 of the connecting device 1 according to the first embodiment.

The body 101 , 102 of the connecting device has, according to both the first and the second preferred embodiment, substan- tially the shape of a C. Also the connecting member 1 1 , 41 has substantially the form of a C according to the two preferred embodiments of the manoeuvring arrangement. The C-shape of the connecting member 1 1 , 41 is somewhat larger than the C-shape of the body 101 , 102 in order to receive the body 101 , 102.

The elongated moving member 33, the manoeuvring member 32, and the effect member 34 have the character of a substantially rigid element. They may however be flexible to a certain extent. In other words, the term substantially rigid element relates to the fact that the manoeuvring member is not very flexible or fold- able. Each of the members 32, 33, and 34 may, for example, be formed by a bar or a rod. Suitable materials for the elongated moving member 10, 33, the manoeuvring member 13, 32, and the effect member 34 are glass-fibre and plastic. The manoeuvring member 13, 32, the moving member 33, and the effect member 34 may, for example, have a telescope function for obtaining the displacement of the device 1 .

It should be noted that the description presented here above and illustrated in the drawings only should be considered as exemplifying for the inventive idea, on which the invention is built. Thus, it is obvious for the man skilled in the art that detailed modifications may be made after having been presented to the inventive idea without leaving the scope of the invention.

For example, the connecting device may be equipped with a plurality of spaced pressure means 108 for achieving said contact pressure.

It is also possible to provide the connecting device with a re- leasably arranged cover member, which in a first position allows insertion of the conductor portion through the opening , and in a second position cover the opening, or a displaceably arranged casing for counteracting the gathering of moisture, dirt, and similar on the inside of the opening. Thanks to the fact that the manoeuvring arrangement is detachable from the connecting device, it is, of course, suitable to use only one manoeuvring arrangement for applying a plurality of connecting devices.

The term conductor comprises both a high-voltage line and a high-voltage tube.

The attaching members 1 1 1 , 1 18 do not necessarily need to be located at the lower portion 161 of the body, but may instead be located, for example, at an upper portion 160 of the device provided that they allow manoeuvring from below and/or from a position substantially on the same level as the conductor.

It is further possible that the connecting device is lifted a dis- tance from the ground by means of a lifting device in order to be applied to the conductor from that position by means of the manoeuvring arrangement.

The pressure means 108 may, for example, have a piston- cylinder apparatus in order to obtain said contact pressure.

The engagement member 54 of the elongated effect member 34 may be powered electrically.

The displacing member 42 may be arranged in a plurality of different ways, such as an element sliding towards the manoeuvring bar 32.

It is obvious that the described moving arrangement also may be used for connecting other objects to the conductor than the above described connecting device. Examples of such objects are earthing elements and signal balls. Said connecting device may, of course, be used for connecting an electric apparatus other than a diverter.
