Definitions
- the invention relates to a disconnector for a multi-pole switchgear panel of a metal-encapsulated, compressed gas-insulated high-voltage switchgear, in which each pole is accommodated in an encapsulation housing which has two bushing insulators, and the ends of the conductors penetrating the bushing insulators are each surrounded by a rounded shielding body and connected to it, which limit the separation distance and of which the first shielding body contains a movable contact element which is in contact with the end of the first conductor and can be actuated by a drive via a rotary insulator and which, when the separation distance is bridged, emerges from an opening in the first shielding body and engages with the
- the same longitudinal axis has the opposite end of the second conductor lying in the second shielding body, the rotary insulator standing perpendicular to the longitudinal axis of the movable contact.
- Such a switch constructed as a single-pole push-pull disconnector, with shielding bodies around the conductor ends is known and is e.g. on page 701 of the Brown Boveri Announcements 1979.
- the first shielding body into which the rotary isolator which triggers the actuation of the isolating switch is inserted, contains both the movable contact piece and the means for converting the rotary movement of the rotary isolator into the pushing movement of the movable contact piece.
- the disconnector is open, the separation distance is limited by the two rounded shielding bodies.
- the known disconnector is a line disconnector, i.e. the movable contact piece and the ends of the conductor that can be bridged by it lie on a common longitudinal axis.
- the encapsulation housing is accordingly approximately cylindrical and its end faces are closed off by the bushing insulators for the conductor ends.
- the invention has for its object to design a circuit breaker so that regardless of the course of the conductors each circuit breaker pole always contains the same parts within the encapsulating housing and with the shortest possible current path length, a minimum of components and housings is achieved.
- a circuit breaker of the type described above is constructed such that the rotary isolator is perpendicular to the phase current path plane of the switch panel and that the first shielding body is essentially designed as a ball, the center of which is on the axis of the rotary isolator and on the longitudinal axis of the movable contact piece and which has a surface in the inside for receiving the fastening means required for connection to the end of the first conductor, the central perpendicular of which lies in the phase current path plane of the switch panel.
- the position of the movable can be turned by rotating the ball around the rotary insulator Switch piece can be changed, the central perpendicular of the connection surface for connection to the end of the first conductor remains in the phase current plane. Due to the corresponding alignment of the opposite end of the second conductor lying in the second shielding body, this twist achieves the adaptation of the disconnector to different angular conductor runs without the field conditions or the dielectric strength practically changing in the region of the isolating path, since these change also turns.
- the encapsulation housing has a spherical section with the same center, at least in the region adjacent to the spherical of the first shielding body. Then, when the ball of the shielding body is rotated, the expansion of the ball section of the encapsulation housing is changed accordingly, so that in this region adjacent to the ball of the first shielding body there is no distorting change in the field and the dielectric conditions are not deteriorated.
- a further simplification of the storage can be achieved in that in the inside of the ball of the first shielding body several surfaces are provided at an angle to each other for receiving the fasteners required for connection to the end of the first conductor, the center perpendicular of which in each case Phase current path level of the panel.
- the ball of the first shielding body is prepared from the outset for connection to various conductor tracks which are at mutually desired angles. For the final use of the ball, only the necessary connection surface for the end of the first conductor lying on the outside of the ball, which is easy to machine, is then produced for the selected inner surface.
- Disconnector poles designed in this way can be combined in any way in a multipole switch panel. It is expedient if, in the case of a three-pole switch panel, the isolating paths are oriented differently to the axis of the first conductor in each or in two of the isolating switch poles belonging together.
- FIGS. 1 to 5 show, each schematically, in longitudinal section a disconnector designed according to the invention in the open switch position.
- FIG. 2 shows the first shielding body of this circuit breaker on an enlarged scale, partially in section, in the arrangement shown in FIG. 1.
- FIG. 5 shows, likewise schematically, a side view of part of a switch panel in which a plurality of disconnectors designed in accordance with the invention are used.
- the disconnector according to Figure 1 is a line separator, i.e. the two ends of the first conductor 1 and the second conductor 2 to be separated or bridged lie on the same longitudinal axis.
- Both conductors 1, 2 are held at a central distance from the encapsulation housing 4 by bushing insulators 3.
- the ends of both conductors 1, 2 are also surrounded by rounded shielding bodies 5, 6, which act as field electrodes.
- the first shielding body 5, which is in contact with the end of the first conductor 1, is essentially designed as a hollow ball 7.
- the second shielding body 6 surrounds the end of the conductor 2, which forms a current lamella contact 8.
- the hollow ball 7 of the first shielding body 5 contains the movable contact piece 9 (see FIG. 2), which lies on the longitudinal axis of the conductors 1, 2. It is located completely inside the shielding body 5 when the disconnector is in the open switch position, so that the open separating path 10, indicated by arrows, is delimited by the shielding bodies 5, 6.
- the actuation of the movable contact piece 9 for bridging or opening the isolating section 10 is effected by a drive (not shown) lying outside the encapsulation housing 4, which is connected to the movable contact piece 9 via a rotary isolator 11 and gear parts (not shown).
- This rotary insulator 11 is perpendicular to both the longitudinal axis of the conductors 1, 2 and perpendicular to the phase current path plane of the switch panel and is guided into the shielding body 5.
- the means for converting the rotary movement of this rotary isolator 11 into the pushing movement of the movable contact piece 9 are also inside the shielding body 5 and are not shown.
- three adjacent surfaces 12, 13, 14 are further provided, which are at an angle of 45 ° to one another. These inner surfaces 12, 13, 14 serve to receive the fastening means required for connection to the end of the conductor 1. Their perpendicular bisectors, not shown, lie in the phase current path plane of the switch panel, which corresponds to the paper plane of the drawing.
- the first shielding body 5 can be rotated around the rotary insulator 11 and in each case connected to the end of the conductor 1 via a connection surface on the outside of the ball 7 which is assigned to one of the inner surfaces 12, 13, 14.
- FIGS. 1 and 2 corresponds to that of a line separator in which the conductors 1 and 2 are at an angle of 180 ° to one another.
- the encapsulation housing 4 is correspondingly formed in the region adjacent to the ball 7 as a ball section 16, this ball section 16 and the ball 7 having a common center point. This results in simple field conditions in this area.
- the spherical section 16 is followed by an approximately cylindrical connecting piece 17 or 18, which leads to the flange 19 of the bushing insulators 3.
- the connecting piece 17 is longer than the connecting piece 18, since it also surrounds the second shielding body 6.
- FIG. 3 shows a circuit breaker with a different arrangement of the first shielding body 5, the same reference numerals are retained for the same parts.
- the ball 7 of the shielding body 5 is fastened to the inner surface 13 (see FIG. 2) and the associated outer connection surface at the end of the conductor 1.
- the position of the opening 15 and that of the movable contact piece 9 rotates relative to the conductor 1, the rotary insulator 11 forming the axis of rotation.
- the end of the conductor 2 and the shielding body 6 surrounding it are now arranged so that the longitudinal axis of the conductor 2 corresponds to the longitudinal axis of the movable contact piece 9.
- the position of the separation section 10 has changed accordingly.
- FIG. 4 a disconnector is shown in FIG. 4, in which the ball 7 of the first shielding body 5 is fastened to the end of the conductor 1 via the inner surface 14.
- a disconnector is obtained in which the conductors 1 and 2 are at right angles to one another.
- the proportionate areas of the connecting piece 17, the spherical section 16 and the connecting piece 18 have shifted relative to one another for the encapsulating housing 42 without the dielectric conditions in the interior of the encapsulating housing 4, in particular in the region of the isolating section 10, having changed practically.
- the bushing insulator 3 for the end of the second conductor 2 surrounded by the second shielding body 6 is always at the same distance from the center of the ball 7 of the first shielding body 5, regardless of the inner surface 12, 13, 14 or outer connection surface is attached to the end of the first conductor 1. This results in an optimally short current path length.
- FIG. 5 now shows a side view of part of a three-pole switchgear panel of a metal-encapsulated, pressurized gas-insulated high-voltage switchgear assembly in which isolating switch poles designed according to the invention are used.
- the three phases RST are in a row.
- phase R the conductor course is indicated as a circuit diagram.
- An angular housing 20 is visible from the front phase R, on the central upper flange 21 of which the encapsulating housing 4 is flanged a disconnector pole 22 designed according to the invention.
- This isolating switch pole 22 connects the conductor 23 within the angular housing 20 to the busbar 25 accommodated in the encapsulating housing 24 flanged to the encapsulating housing 4 above.
- the isolating switch pole 22 in the phase R switching field thus corresponds to the line separator according to FIG of 180 ° to each other.
- phase 5 lying behind, the conductors of the isolator switch pole have an angle of 135 ° to one another, so that the isolator switch pole accommodated in the encapsulation housing 41 corresponds to the isolator switch pole according to FIG.
- the isolating switch pole lies within the encapsulation housing 42 and connects two conductors at an angle of 90 ° to one another.
- the dielectric conditions of the isolator system are practically the same for all versions.
- the encapsulating housing of the isolating switch can also have other connection pieces with flanges, provided that this is necessary for assembly openings or for the connection of other modules of the switch panel.
