Definitions

  • the invention relates to a load switch according to the preamble of claim 1.
  • a switch disconnector of the type mentioned becomes, in which the load switch is housed within a push tube, whereby the thrust tube the distance between two fixed when switched on Contact elements bridged.
  • the load switch is inside the Push tube and is held in place by a lock during the switch-off process.
  • the object of the invention is to provide another solution for a load switch at the beginning to create the kind mentioned.
  • the vacuum chamber is held in that the fixed contact stem has a locking head, the so of a resilient locking device long held until on the one hand the push tube a sufficient distance from has the associated contact element and on the other hand the contact point within the vacuum chamber is separated.
  • the load switch 10 according to FIG. 1 has contact elements arranged at a distance from one another 11, 12, which are resiliently pressed in as contact fingers and a thickening 13, 14 at their respective free ends, which have to face each other.
  • a push tube 15 made of electrical conductive material which is electrically connected to the thickenings 13 and 14 is and in the switched-on state to bridge the contact element distance serves.
  • a vacuum chamber 16 which has a ceramic cylinder, is arranged inside the push tube 15 17, which at both ends by means of a cover 18 and 19 is closed, the cover 19 having an opening, not shown, in its Middle.
  • the cover 18 is penetrated by a fixed contact stem 20, the fixed contact stem 20 is connected to the cover 18 in a vacuum-tight manner.
  • the inner free end of the fixed contact stem carries a fixed contact piece 21.
  • the cover 19 is penetrated by a movable contact stem 22, between a bellows 23 is arranged on the cover 19 and the contact stem 22, by means of which the vacuum chamber is closed in a vacuum-tight manner, with free mobility of the movable contact stem is achieved.
  • a movable contact piece 24 On the fixed contact piece 21 facing end of the contact stem 22 is a movable contact piece 24 attached.
  • the free end of the fixed contact stem protruding from the cover 18 is provided with a locking head 25 with an enlarged diameter, which is switched on State behind a locking device formed from two locking springs 26 and 27 28 engages; the figure shows two locking arms 26, 27; it can of course also be more.
  • a receptacle 29 adjoins the outside of the cover 19, the bottom 30 of the receiving pot 29, see Fig. 2, with the movable contact stem 22 fixed connected is.
  • a contact pressure spring 32 Within of the receptacle between the piston 31 and the bottom 30 is a contact pressure spring 32 provided the movable contact stem 22 and thus the movable Contact piece 24 presses against the fixed contact piece 21.
  • a return spring 33 is attached at one end to the movable contact stem 22, the other end of which is attached to a bottom 34 of the push tube 15.
  • On the push tube 15 is attacked by a switch-off drive, which is indicated by the arrow 35.
  • On the movable contact stem 22, a contact pot 36 is also attached, the for an electrically conductive connection between the movable contact stem 22 and the push tube 15 provides.
  • the vacuum chamber is opened and the movable contact piece 24 moves away from the fixed contact piece 21 until the distance D is reached which corresponds to the insulation distance of the contact pieces in the vacuum chamber.
  • the force of the return spring 33 is greater than that Locking force of the locking device 28 so that the locking head 25 is released and the load switch is moved to its open position.
  • the push tube 15 is dimensioned so that the locking head in the off Condition behind the front edge disappears.
  • the locking force between the locking head and the locking device is greater than that Maximum force of the return spring and the return spring only reaches about halfway of the entire switching stroke the same spring force as the contact pressure spring.
  • the system requires exact coordination between the contact pressure spring the vacuum chamber and the return spring, as well as to the locking device 28
