Definitions

  • the invention relates to a high-voltage switchgear with a vacuum chamber and a switchgear with a high-voltage switchgear.
  • the invention also relates to a method for producing a high-voltage switching device with a vacuum chamber.
  • switchgears are used to distribute electrical energy.
  • Switchgear systems have switching devices that establish or separate an electrically conductive connection between electrical contacts.
  • high-voltage switching devices are used that meet the electrical requirements for the high voltages in high-voltage or medium-voltage networks.
  • the voltages of the high voltage networks are generally between 60 and 52 kV and the medium voltage networks between 1 kV and 52 kV.
  • High-voltage switching devices which have a vacuum chamber in which the electrical contacts are arranged.
  • switching devices are also known in which the electrical contacts are in a gas atmosphere made of insulating gas, for example SF 6 .
  • insulating gas for example SF 6
  • the use of vacuum chambers offers the advantage that load currents and short-circuit currents can be interrupted in a relatively small volume without the risk of hot switching gases being emitted.
  • a particularly long insulation path is required in air-insulated switchgear, which is why these switchgear take up a lot of space.
  • Vacuum chambers are used in switching devices with circuit breakers, earthing switches, disconnectors or switch disconnectors.
  • Switching devices with vacuum chambers are for example from the DE 31 12 776 A1 and DE 40 27 723 A1 famous.
  • the known vacuum chambers have a housing body in which an immovable switching contact and a movable switching contact are arranged.
  • the movable switch contact is operated by an actuation unit.
  • the actuation unit can be driven by an electric drive unit.
  • the vacuum chamber is inserted into a potting mold and encapsulated with a potting compound, for example epoxy resin, so that the vacuum chamber is enclosed by a solid potting housing after the potting compound has hardened.
  • the components of the housing body of the vacuum chamber which can consist of ceramic or metallic materials, for example copper, expand more than the solid potting housing. This can lead to mechanical stresses and the associated fine cracks in the solid plastic encapsulation. The service life of the switching device can thus be reduced considerably. In addition, unexpected flashovers can occur.
  • vacuum chambers in high-voltage switchgear are provided with an outer silicone layer or welded in with a shrink tube.
  • the silicone coating or the use of shrink tubing should not only prevent the creation of mechanical stresses, but also offer the advantage that a sufficient insulation distance is created between the fixed and the movable switching contact along the outside of the vacuum chamber. This is to avoid external flashovers over the vacuum chamber.
  • the coating of the vacuum chamber is a critical element of the switching device, especially at higher voltages, for example voltages from 20 kV to earth or from 36 kV linked voltage. Tests have shown that flashovers between the silicone coating and the vacuum chamber can also occur in vacuum chambers coated with silicone.
  • a switching device which has a vacuum interrupter chamber (inner vacuum interrupter layer) which is enclosed by an intermediate layer and an outer insulating layer.
  • the vacuum interrupter chamber is inserted into a first mold, the space in between being potted with a hardening elastomeric resin.
  • the vacuum chamber, which is enclosed by the potting compound, is then inserted into a second mold, the intermediate space being potted again with a potting compound.

Machining the surface of the housing body of the vacuum chamber with glass ball beads has proven to be particularly advantageous.
