Definitions

  • the invention relates to a high-voltage circuit breaker with a first and a second, coaxial with each other opposite arcing contact piece, between which at a switch-off optionally a switching arc burns and the in the course of a Ausschaltvorganges by a common drive drivable in opposite directions are, wherein the drive movement by a first drive element on the first arcing contact piece and through a second drive element by means of a deflection gear the second arcing contact piece is transmitted and with two persistent contact pieces coaxially surrounding the arcing contact pieces and with an insulating nozzle, with the first arcing contact piece is firmly connected and the the blowing of the switching arc with a quenching gas is used.
  • the present invention is based on the object, a High-voltage circuit breaker of the type mentioned above create, structurally simple and inexpensive is and claimed the smallest possible housing size.
  • the object is achieved in that the second drive element attached to the insulating nozzle and is driven by this and the deflection gear a Fixed pivotally mounted two-armed lever, to the second drive element and the second arcing contact piece are coupled to coupling points.
  • the second drive element on the insulating material is attached, and the insulating nozzle thus even the Transmitting drive power to the second arcing contact, the second drive element can be kept relatively short become.
  • the Isolierstoffdüse drives in turn the second drive element, which the drive movement on the behind the second arcing contact piece arranged deflecting transmits. By means of the deflection gear the drive movement is then on the second arcing contact piece transfer.
  • the size of such a high-voltage circuit breaker is exactly the size of a corresponding switch, in which only one of the arcing contact pieces can be driven and in which the second drive element and the deflection gear absence.
  • the switch can thus the same Isolierstoffgeophuse, for example, used porcelain housing become.
  • the second drive element with the arc or with hot extinguishing gas may come into contact, it should come from a arc-resistant material, such as PTFE produced become.
  • the distance between the coupling point of the second arcing contact piece and the coupling point of the second drive element, especially under load of the deflection, changeable is.
  • a change in the distance between the coupling point the second arcing contact piece and the coupling point the second drive element allows in a simple manner to change the transmission ratio of the reversing gear. Especially with a change in the distance during a transmission of a drive movement via the deflection gear, d. H. under load of the deflection, can the second arcing contact deliberately accelerated or slowed down.
  • a coupling point slidably guided in a backdrop.
  • a backdrop-like guidance of a docking point in one Long hole provides a reliable connection with the lever Through the slot it is possible in a simple manner, the distance between the coupling points of the second Drive element and the arcing contact piece variable too to change.
  • the second drive element radially within the persistent contact pieces is arranged.
  • An advantageous embodiment of the invention can provide that at the reversing gear a the second arcing contact piece surrounding field electrode is coupled in the course a switching movement in opposite directions to the second arcing contact piece is movable.
  • a further advantageous embodiment of the invention can Provide that the second arcing contact piece and the Field electrode are coupled to the two-armed lever.
  • the reversing gear is in the simplest and functionally safe manner feasible.
  • the reversing gear from the first arcing contact piece is arranged behind the second arcing contact piece is ensures that both arcing contact pieces at the turn-off, which requires extremely high acceleration be driven by a pulling movement.
  • the rest position of the two-armed lever can be a suitable Acceleration profile of the second arcing contact piece be realized during the switch-off.
  • a Overlift of the drive can be compensated.
  • the figure shows schematically in a longitudinal section a Interrupter unit of a high-voltage circuit breaker.
  • the illustrated high voltage circuit breaker has two Arc contact pieces 1, 2, which face each other coaxially.
  • the illustration shows a state during the Switching movement shortly before reaching the switch-off state.
  • the Arc contact pieces 1, 2 are already separated and between them burns an arc 3.
  • the first Arc contact piece 1 is in the direction of the arrow 12, the second arcing contact piece 2 moves in the direction of the arrow 13.
  • the first arcing contact piece 1 is hollow and takes in the on state, the pin-shaped second arcing contact piece 2 on.
  • the first arcing contact piece 1 is coupled to a contact tube 4, which is also the first drive element does not serve and the drive movement of one transfers illustrated energy storage.
  • the first arcing contact 1 carries a multi-part Isolierstoffdüse 9, which in the on state, the second arcing contact piece 2 surrounds and during the turn-off the heated by the arc 3 extinguishing gas passes.
  • First can through a channel 14 hot extinguishing gas in a boiler room 15 stream out of it at a suitable time, shortly after Current zero crossing of the alternating current to be switched through the same channel 14 flows back to the arc third to blow and reconsolidation of the switching path too accelerate.
  • the free end of the insulating nozzle 9 is guided in a tube 10, which simultaneously forms a field electrode.
  • a drive element 5 attached in the form of a rod made of PTFE.
  • a ring 16 attached, with one end of the second drive element 5 is screwed.
  • the second drive element 5 is the two-armed lever 11 is actuated.
  • the rod 5 is pulled in the direction of arrow 17, whereby the lever 11 is pivoted clockwise. hereby is a pulling movement in the direction of arrow 13 on the second arc contact piece 2 transmitted.
  • the second arcing contact piece 2 is by means of a Gleitcard arrangement 20 in the axial direction within the field electrode 10 led and contacted.
