Definitions

  • the invention relates to a switching device with a Switch lock that has a gear lever, a pawl and one Pawl lever as a counter bearing for the pawl, which is when triggered rotates around its bearing axis and the gear lever releases for the actuation of contacts, and with one with the Switch lock in operatively connected handle.
  • a generic switchgear is used by several electrical companies expelled.
  • the switch lock 1 is in this position in the latched state in which the main contacts of the circuit breaker only one main contact 3 is shown here is closed. Only when the key switch is triggered 1 acts a shift lever 2 on a slide and a rocker connected to it, through which the main contacts 3 be opened. At the same time, the control shaft 2 acts on one Contact bridge carrier 4 of a coupled auxiliary switch HS.
  • the switch lock 1 is essentially a lever system with a handle 5, a pawl 6 and a release lever 7 composed. The ON position shown here is caused by the position of the handle 5. About a connected to the handle 5 rod 8 is the The position of jack 6 can be changed in a guided manner.
  • the handle 5 is a fixed one Lever which e.g. designed as a rocker arm or rocker can be.
  • 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 here with the help of two compression springs, a slide and realized a lever.
  • Jack not shown here actuates the with a compression spring preloaded lever, one with another Pressure spring preloaded slide unlatched.
  • the slider slides forward and blocks the turning back of the counter wheel belonging to the rotary drive.
  • the compression spring of the Slider thus counteracts the torsion spring in the rocker and thus prevents turning back.
  • the one not shown here latches Pawl on the pawl lever and the switch can be switched on again become.
  • DE 92 06 137 U1 discloses a circuit breaker with a Switch lock that corresponds to the type mentioned in the introduction.
  • the key switch also has a gear lever here, a pawl and a pawl lever as a counter bearing for the pawl, which is triggered around its bearing axis rotates and releases the switch lever for actuating contacts.
  • the circuit breaker is in contact with the Key switch in operative connection. A tripped position, through which indicates to the operator that the key switch has been triggered is, however, the DE 92 06 137 U1 is not removable.
  • the invention has for its object in a switching device of the above type in a simple manner, i.e. with little Realizing a tripped position in terms of costs and parts.
  • Switch lock is arranged a lock when triggered allows the triggered jack to swing through, but that Swinging back of the pawl hinders and the pawl in one holds certain position in which the handle due 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 a trip is present.
  • the lock as a spring arm is designed with the locking head, the one hand with Sliding surfaces and on the other hand is provided with locking surfaces, that the pawl slides along the sliding surfaces as it swings and when swinging back from the restricted areas is held.

  • the Jack 7 due to the force transmitted through the knee joint first on the locking head 11 and then under the ratchet lever 6 passed until it latches on the ratchet lever 6.
  • the switching device can only be switched on after this latching, the opening spring 9 (see FIG 1) biased and thus the energy required to trigger it records.
  • the rotary knob 15 must not move out of the tripped position immediately be turned towards ON because in this case the jack 7 is not yet latched and thus the counter bearing for preloading the switch-off spring 9 is missing. The switching device would be in not turned 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 on the pawl 7 also shown on the one hand hardly hinder when swinging and when Hold back swinging.

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.

Claims (3)

  1. Appareil de coupure ayant un mécanisme (1) de verrouillage, qui comporte un levier (8) de commande, un cliquet (7) et un levier (6) de cliquet, servant de contrebutée au cliquet (7), lequel lors du déclenchement tourne autour de son axe (17) de palier et dégage le levier (8) de commande pour actionner des contacts, et une poignée (15) coopérant avec le mécanisme (1) de verrouillage, caractérisé en ce qu'il est prévu dans le mécanisme (1) de verrouillage, un arrêt (10) qui, lors du déclenchement, autorise le basculement du cliquet (7) déclenché, mais empêche le cliquet (7) de rebasculer et maintient le cliquet (7) dans une position déterminée dans laquelle, la poignée en raison de la coopération est maintenue dans une position intermédiaire entre la position fermée et la position ouverte de l'appareil de coupure.
  2. Appareil de coupure suivant la revendication 1, caractérisé en ce qu'après déclenchement, la poignée (15) doit être actionnée dans le sens d'ouverture, le cliquet (7) passant, en raison de la coopération, devant la tête (11) de l'arrêt (10) et s'encliquetant sur le levier (6) de cliquet, avant que l'appareil de coupure ne prenne la position fermée.
  3. Appareil de coupure suivant la revendication 1 ou 2, caractérisé en ce que l'arrêt (10) comporte un bras (16) élastique ayant une tête (11) d'arrêt, qui est munie d'une part, de surfaces (12) de glissement et d'autre part, de surfaces (13) d'arrêt, de façon que le cliquet (7) glisse lors du basculement le long des surfaces (12) de glissement et soit maintenu lors du rebasculement, par les surfaces (13) d'arrêt.
