Definitions

  • the invention relates to an arc extinguishing device for switching devices in electrical power engineering according to the preamble of claim 1.
  • Arc extinguishing devices have the task of extinguishing the arc that occurs in switches when switched off. Such an arc occurs when the contacts are opened due to the evaporation of the last metal bridge due to the current heat. With switch disconnectors and circuit breakers, it is important to make this arc disappear as quickly as possible and to create sufficient insulation between the contacts. While with direct current it is important to achieve a high arc voltage in the switching chambers, alternating current is the effective reduction of the charge carriers in the short time between a zero current crossing and the oscillation of the recurring voltage. It depends very much on the type of switch whether the final power interruption occurs after one or more zero crossings. It is important that the arc gap is sufficiently cooled.
  • Circuit breakers for medium voltage that work according to this method require relatively large quenching chambers, which are very expensive due to their complexity.
  • the invention is therefore based on the object of developing an arc extinguishing device for switching devices, particularly in the medium and high voltage range, which, with the same performance, requires less effort than the previously known devices.
  • the advantages achieved by the invention are that the use of quenching plates reduces the size of the quenching device.
  • this extinguishing device can be easily manufactured and easily installed in existing systems.
  • a movable contact piece 1 designed as a double separating knife is shown, the pivot point of which rests on a bushing 2.
  • the convenient contact piece is connected to a coupling rod 3 belonging to a drive.
  • the counterpart to the movable contact piece forms a fixed contact piece 4, which is fastened on a busbar 5.
  • Supports 6 are used to hold the busbar.
  • the quenching chamber device consists of a quenching chamber 7 which is equipped with a plurality of quenching plates 8.
  • the quenching plates are arranged parallel and overlapping, the arc inlet openings 9 pointing towards the movable contact piece.
  • the arc entry openings are further arranged such that the distance between the end of the movable contact piece and the individual arc entry openings increases as the opening of the movable contact piece increases.
  • the individual quenching plates are surrounded by quench chamber walls 10.
  • Plastic holders 11 and 12 establish the connection between the two arcing chamber walls. In addition, the plastic holder 12 still serves to secure the arcing chamber on the busbar.
