Definitions

  • the invention relates to a vacuum switch with two protruding into a quenching chamber, which are connected outside the quenching chamber via flexible conductors with electrical terminals, one of which has a fixed position with respect to the quenching chamber and of which the other contact via an actuating mechanism coupled to a switching drive relative to
  • the quenching chamber can be moved between an open position and a closed position of the contacts and can be pivoted with the quenching chamber and the contact fixed to the quenching chamber.
  • Such a vacuum switch is known from the catalog vacuum protection SV-7 from EMA-Elester, printed in Tru in 1976.
  • the ends of the bolt-shaped contacts located outside the arcing chamber are connected to the actuating mechanism via a ball joint and to the switch housing via a cardan joint, so that the arcing chamber forms a pendulum construction with the contacts.
  • the friction present in the joints leads to games over a longer period of time, which impair the opening width and the simultaneous establishment of contact.
  • the structure of the pendulum construction is complicated and expensive.
  • a circuit breaker is also known, in which the contacts are located in a tank filled with oil and the contact is made via a complicated cable and linkage drive. Irrespective of its complex design, such a circuit breaker is not suitable for use as a contactor with a high frequency of shadows.
  • the object on which the invention is based is to design the vacuum switch of the type mentioned at the outset with structurally simple means for the reliable execution of high switching cycles.
  • Ropes or chains are advantageously used as traction means, while threaded sleeves are advantageously used as tendons.
  • the vacuum switch according to the invention has the advantage that, due to the traction means used, its construction is extremely simple and, by excluding play, the reliable operation is guaranteed even with a large number of switching changes.
  • the vacuum switch shown in the drawing only with its essential parts has a vacuum quenching chamber 1 with a first pin-shaped contact 2 and a second pin-shaped contact 3, the contact surfaces of which are located in the vacuum quenching chamber 1 and the free ends of which are led out of the vacuum quenching chamber 1.
  • a first pin-shaped contact 2 At the free end of the first pin-shaped contact 2, one end of a first pulling cable 4 and one end of a first flexible conductor 6 are fastened, which lead to an electrical terminal (not shown).
  • the other end of the pull cable 4 is attached to a threaded sleeve 7 which is connected via a nut 9 to a movable part 8 of an actuating mechanism of the vacuum switch.
  • a hollow cylindrical intermediate element 10 is attached.
  • the second pin-shaped contact 3 has an outer conductive element 17, on which a second flexible conductor 16 is fixed with a nut 18 placed on the intermediate element 10.
  • the second conductor 16 is connected to a terminal, not shown.
  • a roller 11 is held, in which one end of a second traction cable 12 is fastened, which extends through an opening in the bottom of the intermediate element 10 and is fixed with its other end in a threaded sleeve 13 which is attached to an immovable part 14 of the vacuum switch is held with two nuts 15.
