Definitions

  • a switching device according to the preamble of claim 1.
  • Such a switching device can perform both separation and grounding functions and is used in gas-insulated, single or multi-phase encapsulated switchgear for voltages of several kV up to several hundred kV. This exploits the fact that the functions of disconnecting and grounding are often required at the same place in the switchgear.
  • the switching device has an encapsulating housing, which is filled with an insulating gas, for example nitrogen, air, sulfur hexafluoride (SF 6 ) alone or in mixture, of up to a few bar pressure and to which a grounding contact is fixed in the interior.
  • an insulating gas for example nitrogen, air, sulfur hexafluoride (SF 6 ) alone or in mixture
  • a disconnector contact fastened to a conductor and a movable contact element displaceable along an axis and movable into or out of engagement with either the disconnector or the earthing contact.
  • a current conductor fixed to a further conductor conductor tube is provided which receives the movable contact element to form a current transition and in particular comprises coaxial.
  • the movable contact element is driven by a guided through the housing drive with force. With a single drive so the functions of the separation and the ground can be realized.
  • the invention makes reference to a prior art of switching devices, as it is, for example Hitachi Review Vol. 51 (2002) No.5 p.169-173 or off EP 1 068 624 B1 or off JP 2000 134733 A (TOSHIBA CORP) yields.
  • the switching devices for gas-insulated, metal-enclosed switchgear described in these prior publications each have a three-position switch, all the functions of a disconnector and a grounding switch with a single drive can perform.
  • a arranged in a Kapselungsgephase, movable contact element is moved along an axis, which axis is guided by a disconnector and a ground contact. With a linear movement of the contact element so three switching positions of the switching device can be achieved.
  • the contact element In a first of these three positions, the contact element is neither in contact with the isolator contact nor with the contact with the earth (neutral position), ie both an integrator integrated in the switching device and an integrator integrated into the switching device are open. In a second position, the contact element engages in the isolator contact. The disconnecting point of the disconnector is now closed when the earth electrode is open. In the third position, the contact element engages in the grounding contact. The earth electrode is now closed with disconnector open.
  • Driving force for the movable contact element is transmitted transversely to its direction of movement.
  • the encapsulating housing requires additional space transverse to the axis (Hitachi Review) or it is a specially designed and a lever gear receiving conductor needed ( EP 1 068 624 B1 ).
  • the spindle nut and thus the attached movable disconnector contact Upon rotation of the shaft, the spindle nut and thus the attached movable disconnector contact is linearly displaced in the housing and can be brought into or out of engagement with a arranged in the enclosure housing, fixed Trennerumbletern.
  • a co-rotation of the spindle nut is prevented by a guide rail, which is arranged in a contact carrier and aligned in the direction of movement of the movable isolator contact and which cooperates with a sliding body of the movable contact.
  • the invention solves the problem of specifying a switching device of the type mentioned, which can be converted with little effort such that it can perform the functions of separating and grounding, only separating or just grounding as needed ,
  • the drive provided in the switching device comprises a displaceable along an axis and guided in a conductor tube holding body, which is configured to receive two contact tubes, of which a first counter-contact of the stationary ground contact containing earth and a second counter-contact of a Disconnector contact separator forms.
  • a movable contact element of the switching device comprises at least one of the two contact tubes.
  • the movable contact element thus has at least one contact tube, which is connected to the holding body and in particular driven by this and which either the mating contact of a grounding contact containing the grounding or the mating contact of the disconnector contact separator or both the mating contact of a grounding contact containing earthing forms as well as the mating contact of a disconnector contact separator.
  • the at least one contact tube is detachably connectable or firmly connected to the holding body.
  • the holding body is guided axially in the conductor tube and secured radially.
  • the switching device is designed as a combined disconnector and earthing switch (combination separator). It can then be performed in a gas-insulated, encapsulated switchgear the functions separating and grounding with only a single drive having switching device.
  • this requires that separation and grounding point are closely adjacent in the system. Lying separation and grounding point far from each other is removed and only one grounding or separating task to solve, so only one of the contact tubes needs to be removed, z. B. by opening one of the two detachable connections, so as to create a switching device with disconnector or earthing function. Therefore, in gas-insulated, enclosed switchgear, the electrical functions of disconnecting and grounding, only disconnecting or grounding only can be covered with a single type of switchgear. This reduces the costs for warehousing and installation of the system.
  • the switching device according to the invention is particularly compact, if the drive has a spindle gear with an axially and centrally guided by the ground contact threaded spindle and the holding body bearing or forming spindle nut.
  • Driving force is now transmitted exclusively in the direction of movement of the movable contact element. It is so transversely to the direction of motion no additional space needed.
  • the driving force is transmitted only in the form of a rotating rotational movement from the outside through the wall of the encapsulating. On the wall bushing, a required shaft can be easily sealed.
  • the spindle nut is formed by a threaded nut and the ring-shaped and attached to the outer edge of the threaded nut holding body.
  • the holding body can then be formed independently of the nut required to perform the gear function of the spindle and easily provided with two connecting parts, such as external threads, which are required for the production of detachable connections with the two contact tubes.
  • the housing has two openings, of which a first is penetrated by the axis and the implementation of the first conductor and the second is arranged angled relative to the axis and the implementation of the second conductor, so can not only with the switching device with low assembly costs the three electrical functions "disconnect and earth", “alone disconnect” or “earth alone” are performed, but it is then possible for all three electrical functions of the installation of the switching device at an angle in the switchgear. Combination separator, separator or earthing then act on an angularly guided flow path and the earth electrode can optionally be installed without connection function in the system.
  • Longitudinal connection function is achieved when the housing has a third housing opening, which serves to carry out a arranged in line with the second conductor and can be acted upon by high voltage third current conductor.
  • a longitudinal connection of the switchgear is then performed, which in the embodiment connected as a combined with the angled leading first conductor connected separately or can be grounded in the embodiment as only disconnector connected to the first conductor or separated therefrom and in the Embodiment can only be grounded as a grounding.
  • the longitudinal connection with the angled first current conductor can then be connected in an earthable star point.
  • the switching device shown in Fig. 1 is formed as a module of a gas-insulated metal-enclosed switchgear and has a insulating gas-filled metal housing 1 with three openings 2, 3 and 4, which are each bounded by a non-designated flange.
  • the flanges are each the connection with a mating flange, not shown, of a subsequent module of the switchgear.
  • the openings 2 and 3 are each gas-tightly closed by an unspecified barrier insulator which is electrically insulated from the housing 1 and carries a high-voltage current conductor 5 and 6, respectively.
  • the opening 4 is optionally closed gas-tight with a blind flange or with a likewise carrying a current conductor 7 bulkhead insulator.
  • insulators and support insulators can be used with gas passage openings.
  • Centrally through the opening 3 performs an axis 8, which determines the direction of movement of a movable contact element 9 of the switching device and along which the current conductor 6 is guided from the outside into the interior of the housing 1.
  • the openings 2 and 4 face one another in the housing 1 in such a way that the current conductor 5 and the possibly provided current conductor 7 are aligned along a line 10 guided centrally through the openings.
  • Axis 8 and line 10 enclose a right angle with each other and thus determine the geometry of a current path containing the current conductors 5 and 6.
  • a conductor tube 11 or hollow carrier 11 is electrically conductively attached, which or which surrounds the contact element 9, preferably coaxially, and with this irrespective of its position over two non-designated sliding contacts resistant forms a current transition ,
  • the along the axis 8 feasible contact element 9 of the switching device is attached to a support body 12 and preferably releasably secured.
  • the holding body 12 is part of a longitudinal axis 8 gas-tight guided through the wall of the housing 1 drive 13 and can be moved along the axis 8.
  • the at least one contact tube is thus driven by the holding body. Accordingly, the position of the contact element 9 changes so. In a first position apparent from Fig.1 then the contact element 9 is only in electrical contact with the contact tube 11. In a second (not apparent from Fig.1) Position it is shifted to the left and then engages in an electrically conductive manner in a grounding contact 14, which - optionally electrically isolated - is attached to the housing 1 and the drive 13 coaxially surrounds.
  • the switching device then acts as a ground electrode E.
  • the contact element 9 is shifted to the right and then engages in an electrically conductive manner in a contactor 15 surrounding the contact element 9 and attached to the current conductor 6.
  • the switching device then acts as a separator T.
  • the contact element 9 contains two contact tubes 9 'and 9 "which coaxially surround the axis 8 and which are detachably connectable or firmly connected to the holding body 12.
  • the holding body therefore has means for receiving the two contact tubes
  • the contact tubes extend from the holding body 12 to the left (direction of fixed grounding contact 14) or to the right (direction of fixed isolating contact 15) .
  • the single drive 13 can thus save space in a space-saving manner the functions of the earthing E and of the disconnector T.
  • the contact tube 9 "only the function of the earth electrode E and after removal of the contact tube 9 'only the function of the separator T are executed.
  • the switching device can therefore be designed as a combined earth electrode E and separator T, depending on the intended use in the switchgear, or only as a simple earth electrode E or separator T.
  • An example of such a simple earth E is FIG. 3 and that of such a simple separator T is shown in Fig.4.
  • an angled, groundable or separable current path is provided, which is likewise guided through the openings 2 and 3.
  • Through the opening 4 can be realized at the same time for all three types of switching devices in addition to the functions earth and separation, only earth or only separating and the angle connection function additionally a longitudinal connection function.
  • switching device according to Figure 5 b) is guided through the opening 4 of the current conductor 7, which forms a longitudinal connection together with the guided through the opening 2 conductor 5.
  • This longitudinal connection can be seen optionally grounded, connected via the disconnector T to the current conductor 6 with the earth electrode E open or insulated with the earth electrode E and open disconnector T through the housing.
  • the drive 13 of the movable contact element 9 may comprise a push rod or a lever guided through the wall of the housing 1, since the displacement of the contact element 9 is made possible by this means.
  • a spindle drive integrated into the drive which has an axially and centrally guided by the grounding contact 14 threaded spindle 16 and a holding body 12 supporting or forming spindle nut 17 (Fig.1) ,

  • the section 19 is made of insulating material and thus isolates the guided through the wall of the housing 1, rotatably mounted in the ground contact 14, metal portion 18 of section 20.
  • the section 20 carries a cooperating with the spindle nut 17 external thread.
  • three sliding bodies 21 are provided which cooperate with one of three axially aligned in the conductor tube 11 guide rails 22.
  • the sliding bodies 21 and accordingly also the guide rails are uniformly distributed in the circumferential direction (only two of the three sliding bodies 21 or rails 22 can be seen from FIG. 1).
  • the spindle nut 17 is formed by a threaded nut 23 and the holding body 12.
  • the holding body 12 is designed as a support ring and attached approximately by a screw on the outer edge of the threaded nut 23.
