Definitions

  • the present invention relates to a switching chamber for a gas-insulated high-voltage switch according to the preamble of claim 1.
  • a switching chamber includes an axially symmetrical housing formed and held in the housing contact arrangement with two switching pieces, one of which is arranged along the housing axis movable.
  • the switching chamber housing has two hollow bodies of electrically conductive material and an insulating tube, which keeps the two hollow bodies in the direction of the housing axis at a distance.
  • the switching chamber is at high voltage potential and is particularly exposed when switched off strong electric fields. Since the switching chamber also absorbs the hot arc gases formed during a switching operation, it is also exposed to great mechanical and thermal stresses at the same time.
  • the switching chamber is preferably used in gas-insulated high-voltage switches with a insulating gas-filled, contact-protected container.
  • a switching chamber of the type mentioned is described in US 6,495,785 B1.
  • This switching chamber is disposed in an insulating gas-filled metal container and has a supported by a support insulator 50 axially symmetrical housing in which a contact arrangement with a fixed and an axially movable contact piece is arranged.
  • the switching chamber housing is formed by two electrically conductive hollow bodies 43, 44, mounting ears and flanges 51, which are fastened to the hollow bodies, and by an insulating tube 50 fastened to the mounting parts 51, which guides the hollow bodies in the direction Keep the housing axis at a distance.
  • the hollow body 43 is connected to a movable and the hollow body 44 with a fixed contact piece of the contact arrangement.
  • the two outdoor bushings 41, 42 are placed at high voltage current conductors 45, 47 guided from the outside through the wall of the container 40.
  • the located in the container interior ends of the current conductors 45, 47 are guided to form two electrical connectors in holes, which are formed in the hollow bodies 43, 44.
  • the two hollow bodies shield dielectric heavily loaded areas on the insulating tube 50 and the support insulator 50 and contain exhaust volumes for receiving hot switching arc gases.
  • the object of the invention is to provide a switching chamber of the type mentioned and a gas-insulated high-voltage switch containing this switching chamber, which are characterized by a high reliability with a simple structure.
  • a separation zone which is electrically shielded during operation of the switch is formed, which separates two surface zones of different roughness from one another in the hollow body.
  • the hollow bodies are generally produced as a metal casting and therefore may have roughness depths in the range of 100 and more microns
  • the outer surface of the casting in the dielectric critical areas by machining, in particular turning, milling and / or grinding, and / or by one or more non-machining operations, especially polishing, shot peening, sandblasting, hammering and / or polishing, considerably be reduced.
  • the surface is partially smoothed to surface roughness of a few microns are achieved. This resulting inhomogeneities at the common boundary of the surface zone high and the surface zone of low roughness are now in the electrically shielded separation zone and can no longer reduce the dielectric strength of the switching chamber and thus equipped switch.
  • a particularly effective shielding of the dielectric critical transition region is achieved when the separation zone is formed as a ring extending around the housing axis depression. If the hollow bodies are designed as cast metal parts, then such a depression can be produced directly by casting during selection of a suitable casting mold.
  • a simplification of the construction of the switching chamber while maintaining a high level of operational reliability is achieved in that one end of the insulating tube is mounted with its lateral surface on a guided around the housing axis portion of the inner surface of both hollow body and connected to the bearing point with the hollow body.
  • the connecting means are advantageously arranged in the separation zone.
  • a further simplification of the switching chamber while increasing their reliability is achieved with a hollow body, in the inner surface of a guide ring and / or a contact ring are mounted, which rest on one of the leadership of the switch current and formed as a blow cylinder of a compression device part of the movable contact piece.
  • the switching chamber can be easily and safely connected to a high-voltage current source, if in the lateral surface of the at least one hollow body, a contact surface is formed for supporting a hollow body fixable power connection.
  • the contact surface of the hollow body is integrated into the surface zone of lower roughness.
  • the single figure shows a plan view of an axially guided section through an embodiment of a switching chamber according to the invention with an axially symmetrical and a contact arrangement receiving housing.
  • a switching chamber for a gas-insulated high voltage switch contains a with an insulating gas, such as based on nitrogen and / or sulfur hexafluoride, filled and largely axially symmetric designed housing 1 and a recorded from the switching chamber housing 1 and also largely axially symmetrical designed contact assembly 2.
  • the closed contact arrangement 2 has two switching pieces 3, 4th on, of which the switching piece 3 along the housing axis 5 arranged to be movable and the switching piece 4 is held stationary in the housing 1.
  • the switching piece 4 does not necessarily have to be fixed, it may also be designed to be movable.
  • the housing 1 is formed by two hollow bodies 7, 8 of electrically conductive material, which are rigidly connected to one another via an insulating tube 6. These hollow bodies are generally made of a cast metal, for example based on steel or aluminum, and absorb the exhaust gases formed during a switching operation in the contact arrangement 2.
  • the hollow body 7 can be connected via a power connection 9 and the hollow body 8 via a power connection 10 to high voltage. When the contact arrangement 2 is closed, the hollow bodies 7, 8 conduct current fed to the power connections 9, 10 Contact arrangement 2.
  • this current is transmitted via a contact ring 11 mounted in a section of the inner surface of the hollow body 7 to a metal blowing cylinder 12 and thus to a rated current contact 13 in the manner of a hollow cylinder and to a tubular contact 14 coaxially penetrating the rated current contact 13 the switching piece 3 out.
  • the current is passed directly to a likewise hollow-cylindrical rated current contact 15 and a designed as a pencil arcing contact 16 of the contact piece 4.
  • the blowing cylinder 12 is part of a compression device, which also comprises a fixedly mounted on the switching chamber housing 1, annularly executed blow piston 17 and which blows when opening the contact assembly 2 fresh quenching gas in an arc formed when opening between the two arc contacts 14, 16.
  • a safe displacement of the blowing cylinder 12 and at the same time protection of the contact ring 11 is ensured by a bearing in a subsequent section of the inner surface of the hollow body 7 guide ring 18.
  • the lower end of the insulating tube 6 is mounted with an end portion of its lateral surface and rigidly connected via connecting means 19, such as screws, rivets or splices, with the hollow body 7.
  • the upper end of the insulating tube 6 is connected to a formed in the insulating support ring 20, to which the switching piece 4 is mounted in an electrically conductive manner.
  • the switching chamber housing 1 is mounted on a hollow support insulator 21, which in turn is held on a flange 22 of an insulating gas-filled, the switching chamber receiving metal container.
  • An insulating rod 23 is fixed at its upper end to the lower end of the hollow arcing contact 14. At its no longer apparent lower end of the insulating rod 23 is connected to a likewise not apparent from Fig.1 drive.
  • An enclosed by the hollow body 7 exhaust volume 24 is axially through the blowing cylinder 12 and the blow piston 17, respectively.
  • a transverse wall 25 bounded and inwardly by the gas-tight through the blow piston 17 and the transverse wall 25 guided arcing contact 14.

When switching off, this electric field additionally acts between the two separate contact pieces 3 and 4.
  • dielectric critical transition regions are effectively shielded.
  • Such dielectric critical transition regions are favored by the smoothing of the surface zones 71 a, 72 a, 81 a, 82 a of a hollow body 7, 8 removed from a casting mold although at the border between unsmoothed and smoothed (cast) surface.
  • the surface zones of low roughness are, above all, the mutually facing end faces of the hollow bodies 7, 8 which are connected to one another via the insulating material 6, but also the ends of the switching chamber housing 1, in particular the front side of the hollow body 7 facing the support insulator 21 and the insulating rod 23.
  • the separation zones for example 72 or 81, are generally designed in each case as a recess extending annularly around the housing axis 5.
  • the unsmooth surface zone 71b or 81b immediately formed during casting of the hollow bodies 7, 8 can pass into the smoothed surface zone, for example 72a and 81a, without the dielectric critical transition at the boundary between smoothed and unsmoothed surface zone can be effective.
  • parts, such as the connection means 19, can be arranged in the electrically shielded depression, which parts may otherwise reduce the dielectric strength at this point.
  • the passage openings 29 and 30 are formed in the hollow body 7 and 8 at the loadable with lower electrical field strengths surface zones 71 b and 81 b. In order to avoid unwanted field increases, these passages each one in the exhaust volume 24, respectively. 27 directed securing edge, which, however, is visible only at the opening 29.

In the two power connections lying counter contact surfaces are formed on the two contact surfaces. These measures ensure a good current transfer from the power connection 9 or 10 to the switching chamber. Since the smoothed contact surface of the hollow body 7 is integrated into the surface zone 71 a, the production of this contact surface is unnecessary in manufacturing technology advantageous manner. As shown in the power connector 10, a current transition can basically also in an unsmoothed Surface zone, here 81 b, on the hollow body, here 8, are fixed, but then the contact surface is made by smoothing a portion of this surface zone.
