Definitions

  • the invention relates to a multi-pole high-voltage circuit breaker according to the preamble of claim 1.
  • a lever switch with an upstream position is also known.
  • the stationary contact piece is equipped with a low-end protruding end, which is surmounted by a subsequent higher section.
  • a contact jaw of a movable contact piece consisting of two contact jaws has an extension.
  • the higher section of the stationary contact piece and the extension of the one contact jaw of the movable contact piece form the ballast (DE-B 974932).
  • the object of the invention is to design the multi-pole high-voltage circuit breaker of the type mentioned in the preamble of claim 1 in a simple manner so that corresponding pre-ignition arcs and cut-off arcs only occur at upstream points and main switching points remain free of erosion.
  • 1 denotes a housing into which two stationary contact pieces 2 project opposite one another.
  • the contact pieces 2 can be connected by a current bridge 3, which is supported by a drive shaft 4 which extends through the housing 1.
  • the contact pieces 2 are designed as contact blades and each have at their end protruding into the housing 1 a thickening 2a formed on their flanks as the main switching point.
  • the thickening 2a is followed by a constriction 2b which projects beyond the thickening 2a in the direction (FIG. 1 ) which is opposite to the switch-on movement of the drive shaft 4 indicated by the arrow.
  • the ends of the current bridge 3 each consist of two contact jaws 3 a that can be expanded by the associated contact piece 2.
  • the inner front edges of the contact jaws 3a are directed inward and form upstream points 3b corresponding to the upstream points 2b of the contact pieces 2.
  • the inner sides of the contact jaws 3a following the upstream points 3b are designed as main switching points corresponding to the main switching points of the contact pieces 2.
  • the described design ensures that when the drive shaft 4 is switched on, the upstream positions of the contact jaws 3 and the contact pieces 2 touch before the main switching points are touched.
  • the housing 1 can be filled with an electronegative gas, for example SF 6 .
  • vanes 4a are arranged on the drive shaft 4, while the housing 1 has inflow walls 1a (FIG. 1).
  • the vanes 4a and the walls 1a are designed and arranged in such a way that, particularly when the drive shaft 4 is switched off, a flow of the electronegative gas which supports the extinguishing of an upcoming arc results.
