Definitions

  • two switching pieces movable relative to one another along an axis limit an arc zone in the axial direction.
  • a switching arc formed hot compressed gas is passed from the arc zone via a heating channel in a coaxial switching parts comprehensive heating volume.
  • the supplied hot compressed gas is mixed with already existing cold gas and performed at approach of the current to be disconnected to a zero crossing as quenching gas for blowing the switching arc in the arc zone.
  • FIG. 5 Another switching chamber of a high voltage switch is in EP 0 163 943 B1 , in particular embodiment according to Fig.2 shown.
  • This switching chamber is designed axially symmetrical and has a designed in the manner of a torus heating volume 5.
  • the heating volume 5 is by an axial guided annular channel 6 connected to a shut-off a current of two switching pieces 2, 3 limited arc zone 8.
  • Through the channel 6 in the heating volume 5 passing hot compressed gas is mixed with cold gas, which is already present in the heating volume 5. It is such a good quality extinguishing gas available, which flows when approaching the current to be disconnected at a zero crossing via the annular channel 6 in the arc zone 8 and the arc burning in this zone 7 can effectively blow.
  • the right end of the contact piece 4 is inserted in an electrically conductive manner in the left end of the tubular contact piece 3.
  • the two switching pieces 3, 4 separate from each other and this forms a footing on the two ends of the switching pieces arc 8
  • the - like Fig.1 is removable - burns in an arc zone 9.
  • the arc zone is bounded axially by the two contact pieces 3, 4 and radially by the insulating nozzle 6.
  • the arc zone 9 communicates with a heating channel 10 which opens into the heating volume 7 coaxially with the arc zone 9 coaxially extending, parallel to the axis 5 extending portion 11.
  • the quality of the extinguishing gas stored in the heating volume 7 for arc blowing and thus also the breaking capacity of the switch chamber depend on the pressure and the temperature of the extinguishing gas. Pressure and temperature are determined by the shape and the volume V of the heating volume 7. While the size of the heating volume 7 only affects the pressure build-up, the shape of the heating volume influences the gas mixing and thus the extinguishing temperature. However, the quality of the extinguishing gas also depends substantially on the flow behavior of the hot gas on the way from the arc zone 9 into the heating volume 7.
