Definitions

  • the invention relates to an electrical switching device for medium or high voltage for interrupting an electrical current path by means of an interrupter unit which is arranged within a housing filled with an insulating material.
  • Such an electrical switching device is known, for example, from US Pat. No. 3,471,669.
  • the known switching device has an interrupter unit for interrupting a current path by means of a movable contact piece.
  • a drive device is provided for driving the movable contact piece.
  • the interrupter unit and the drive device are arranged within a metallic housing.
  • the interrupter unit and the drive device are positioned within the housing by a permanently elastic insulating material.
  • This insulating material is a solid molded body through which a drive rod and the electrical connecting pieces are passed.
  • the present invention is based on the object of designing an electrical switching device of the type mentioned at the outset in such a way that simplified maintenance and assembly of the assemblies surrounded by an insulating material, in particular the interrupter unit, is made possible.
  • the object is achieved according to the invention in that the insulating material is a gel.
  • the insulating material is a soft, vulcanized gel.
  • a soft, vulcanized gel is almost free of cracks and voids on the walls. This ensures that unwanted voids are avoided in these areas.
  • a vulcanizate of this type also has a high level of inherent tack, which allows the insulating material to adhere to surfaces without additional structural devices.
  • An advantageous embodiment further provides that the insulating material contains a silicone.
  • Silicones have favorable dielectric properties.
  • such silicone gels are inexpensive to process. It is also advantageously provided that the insulating material is compressible.
  • the insulating material has small cavities.
  • Such small cavities support the compressibility of the insulating material.
  • the size of these small cavities is chosen so that the partial discharge resistance of the insulating material is not reduced.
  • Such small cavities can be created by foaming the gel or advantageously also in that the insulating material has fillers.
  • such fillers can also be made incompressible.
  • Polyethylene bodies are particularly suitable as fillers. These fillers increase the thermal conductivity of the insulating material and thus help to prevent inadmissible heating of the electrical switching device.
  • the housing is an insulating housing.
  • Such switches can be integrated into existing systems by using standard insulating housings. the. If the use of electrically conductive material is provided for the housing, then such an electrical one
