Definitions

  • the invention relates to a release mechanism with a lockable moving contact, a plunger and a tripping lever. Furthermore, the invention relates to a switching device with such a release mechanism.
  • Magnetic triggers or magnetic tripping systems are used in switching devices in order, for example, to prevent the fusion of current-carrying contact surfaces at high current intensities or to ensure a safe switch-off, if a resulting arc could damage the switching device.
  • Auslose concerns are advantageous, especially because the application of the circuit breaker can be limited by a too long release time.
  • a magnetic release mechanism can be used both at a
  • Offner and normally open contact can be used.
  • the moving contact which ultimately establishes the electrical contact, is locked in the contacted position.
  • the plunger of the release mechanism first has to hit the release lever, which releases the lock and transmits the actuation movement from the plunger to the moving contact.
  • the release lever which releases the lock and transmits the actuation movement from the plunger to the moving contact.
  • Auslosehebels is essential, especially since the moving contact in the locked state can not be moved.
  • the object is achieved by a Auslosemechanismus mentioned above, wherein the plunger is provided both for actuating the release lever provided for unlocking the Auslosehebels and for actuating the BewegCountes itself by the plunger in a first phase of its Betat Trentsbe- movement for direct action over a first active area the shock ice is provided on the trigger lever and is provided in a second phase of its actuation movement for direct action via a second active surface of the bumper on the moving contact.
  • a switching device which has an inventive release mechanism.
  • Auslosemechanismus differs from the conventional chain of action shock-tripping lever-moving contact in that no chain of action of this kind is present, but the plunger is provided to act directly on both directly to the tripping lever, as well as on the moving contact. In this case, however, the order of effect transmission paid particular attention, because this must first ensure a power transmission to the tripping lever to ensure timely unlocking of the moving contact before the ram can continue to act on the moving contact itself and provokes an opening or closing a contact ,
  • Actuation movement of the shock ice again directly an action on a second active surface of the shock ice are executed on the moving contact. Both actions, ie, the Exposure to the release lever and the action on the moving contact take place directly over the active surfaces of the plunger.
  • the first active surface and the second active surface of the plunger are formed in the actuating direction at different points of the plunger. This ensures a time-delayed action on the release lever or the moving contact, at the same time the relative position of the release lever and the moving contact is taken into account in relation to the respective effective area.

  • the plunger 2 acts along the direction of movement B on the flat release lever 3 in such a way that tilting or increased friction of the release lever 3 is avoided by the symmetrical action of the active surfaces 8.
  • a single effective surface pair 8,13 is sufficient for the actuation of the release lever 3.
  • FIG. 2 shows a three-dimensional view of the triggering mechanism of FIG. 1 in the locked, unactuated state. This condition corresponds to the ground state of the triggering mechanism. Neither a movement force transmission of the active surface 8 on the active surface 13 of the release lever 3, nor the Bewegkraftübertragung from the active surface 9 of the plunger 2 on the active surface 14 of the moving contact 1 have occurred so far.

The plunger 2 moves the release lever un- of the rinke 4, thus leaving the area of influence of the rind 4. With the operation ends the first phase, namely the release of the release mechanism, at the end of an intermediate state is reached, as described in Figures 1 and 3.

  • This Rontaktmaschine is interrupted in the following sequence by the imminent action of the shock ice 2 on the active surface 9.
  • the release mechanism is currently in the transition from phase 1 to phase 2, wherein by the continued movement of the shock ice 2, still propelled by the coil 5, a further actuation on the active surface 9 is converted to the active surface 14 of the moving contact 1, the still closed Rontakt on the Rontaktflache 7 opens.
  • the plunger 2 effects both unlocking via the release lever 3, as well as the actual movement of the moving contact 1.
  • care must be taken in the production of the shock ice 2, which distance the active surfaces 8 and 9 assume to one another. If the unlocking requires a certain amount of time, then a greater distance of the active surfaces is to be provided, taking into account the arrangement of the moving contact 1 and the tripping lever 3 within the triggering mechanism.
  • the invention relates to a trigger mechanism with a lockable moving contact 1, a plunger 2 and a release lever 3.
  • the plunger 2 is both provided for actuating the provided for unlocking the moving contact 1 release lever 3 and for actuating the moving contact 1 itself.
  • the plunger 2 is equipped with a first 8 and a second 9 effective area, which are integrally formed at different locations of the plunger 2 and are provided for actuating the release lever 3 and the Bewegmases 1. Because of the first release to be triggered, the release lever 3 is actuated first and after unlocking in the connection of the moving contact 1 itself.

Abstract

L'invention concerne un mécanisme de déclenchement doté d'un contact mobile blocable (1), d'un coulisseau (2) et d'un levier de déclenchement (3). Pour assurer une transmission de force optimale du coulisseau (2) sur le levier de déclenchement (3) et sur le contact mobile (2), ainsi que pour permettre un temps d'opération court, le coulisseau (2) est prévu aussi bien pour actionner le levier de déclenchement (3) prévu pour déverrouiller le contact mobile (1) que pour actionner le contact mobile (1) lui-même. Pour ce faire, le coulisseau (2) est équipé d'une première surface active (8) et d'une deuxième surface active (9) qui sont formées en différentes positions du coulisseau (2) et qui sont prévues pour actionner respectivement le levier de déclenchement (3) et le contact mobile (1). En raison du déverrouillage à déclencher en premier lieu, le levier de déclenchement (3) est d'abord actionné et, après le déverrouillage, le contact mobile (1) mobile.
