Definitions

  • the invention relates to a switching device with a switching lock, which has a switching lever, a pawl and a pawl lever as a counter bearing for the pawl, which rotates when triggered about its bearing axis and releases the switching lever for actuating contacts, and with one with the switching lock operating handle.
  • a generic switchgear is sold by several electrical companies.
  • the switch lock 1 is in this position in the latched state, in which the main contacts of the circuit breaker, of which only one main contact 3 is shown here, are closed. Only when the switching lock 1 is triggered does a switching lever 2 act on a slide and a rocker coupled to it, by means of which the main contacts 3 are opened. At the same time, the control shaft 2 acts on a contact bridge support 4 of a coupled auxiliary switch HS.
  • the key switch 1 is essentially composed of a lever system with a handle 5, a pawl 6 and a release lever 7. The ON position shown here is caused by the position of the handle 5.
  • the pawl 6 Via a rod 8 connected to the handle 5, the pawl 6 can be changed in its position in a link-guided manner. It acts on the position of the switching lever 2, which determines the switching state of main 3 and auxiliary contacts 9 described above.
  • the torque caused by a spring 10 adjusts the selector shaft 2 after the handle 5 has been moved into the OFF position in such a way that the main contact is opened and the action on the contact bridge support 4 of the auxiliary switch ters HS is canceled.
  • the rod 8 forms together with the handle 5 a knee joint.
  • the handle 5 is a fixed lever, which can be designed, for example, as a rocker arm or rocker.
  • FIGS. 8, 9 and 10 An already known version of a tripped position is shown in principle in FIGS. 8, 9 and 10.
  • the solution is implemented with the help of two compression springs, a slide and a lever.
  • the pawl that swings when triggered, not shown here, actuates the lever pretensioned with a compression spring, which unlatches a slide pretensioned with another compression spring.
  • the slide slides forward and thus blocks the turning back of the counter wheel belonging to the rotary drive.
  • the invention has for its object in a switching device of the above type in a simple manner, i.e. to realize a tripped position with low costs and parts.
  • Switch lock is arranged a lock that allows the swinging of the triggered pawl when triggered, but hinders the swinging back of the pawl and holds the pawl in a certain position in which the handle due to the operative connection in an intermediate position between the
  • ON and OFF position of the switching device is held.
  • the operator of the switching device can thus recognize whether there is a trigger.
  • the lock is designed as a spring arm with the lock head, which on the one hand with Sliding surfaces and on the other hand is provided with locking surfaces that the pawl slides along the sliding surfaces when swinging through and is held by the locking surfaces when swinging back.
  • 1 shows a switch lock in the ON position
  • 2 shows a switch lock in the tripped position
  • FIG 3 shows a lock realized in the switch lock in connection with a latch.
  • FIG. 1 shows a switch lock 1 of a switching device with rotary drive. Of the rotary drive, only one counter wheel 2 is shown here, which forms a knee joint in connection with a U-bracket 3. The knee joint is guided in a backdrop 4 in a circuit board 5.
  • Other components of the switch lock 1 fastened to the circuit board 5 are a jack 6, a jack 7, a shift lever 8, and an opening spring
  • the switch lock 1 shown here is in the ON position, in which the pawl 7 is latched to the pawl lever 6 acting as a counter bearing and the switch-off spring 9 acting on the switch shaft 8 by the rotary drive, ie via the counter wheel 2, is biased. If the pawl lever 6 is actuated when triggered, it rotates about its bearing axis. The pawl 7 slips off the pawl lever 6 and describes, under the pawl lever 6, a rotary movement about its bearing axis 17 formed by the leg of the U-bracket 3.
  • the lock 10 arranged under the pawl lever 6 has a locking head 11, which on the one hand has sliding surfaces 12 and on the other hand is provided with locking surfaces 13 that the pawl 7 slides along on the sliding surfaces 12 when swinging through and is held by the locking surfaces 13 when swinging back.
  • the movement by the locking head 11 is almost unhindered.
  • the swinging back of the pawl 7 is hindered to such an extent that the pawl 7 is held in a certain position before it is re-latched.
  • FIG. 2 also shows the handle of the rotary drive, which is designed as a rotary knob 15.
  • the pawl 7 is caught here by the locking surface 13 on the locking head 11.
  • Pawl 7 due to the force transmitted via the knee joint, first pulled past the locking head 11 and then under the pawl lever 6 until it pawls on the pawl lever 6.
  • the switching device can only be switched on after this latching, the switch-off spring 9 (see FIG. 1) being pretensioned and thus absorbing the energy required for tripping.
  • the knob 15 must not be turned immediately from the tripped position in the ON direction, since in this case the pawl 7 is not yet latched and the counter bearing for pretensioning the opening spring 9 is therefore missing. The switching device would not be switched on in this case.
  • FIG. 3 shows the lock 10 with a spring arm 16 and a
  • Locking head 11 This has optimized sliding surfaces 12 and locking surfaces 13, which on the one hand barely hinder the pawl 7, which is also shown, when swinging through and hold on when swinging back.

Abstract

Le mécanisme de verrouillage (1) d'un appareil de commutation est équipé, selon l'invention, d'un système de blocage (10) avec une tête (11), ledit système de blocage (10) comprenant d'un côté des surfaces de glissement (12) et de l'autre côté des surfaces de blocage (13). Un loquet (7) coulisse, une fois libéré, le long des surfaces de glissement (12) et est maintenu par les surfaces de blocage (13) lorsqu'il revient en pivotant.
