Definitions

  • the invention relates to an actuating device for a circuit breaker with a latching device for releasing a first switch position of the circuit breaker and guiding it into a second switch position, the release being optionally mechanically or electrically controllable.
  • circuit breakers of this type two different releases of the latch are therefore provided, the mechanical release of the latch acting directly on the latching device when a pushbutton acts, while when the latch is electrically released, a command circuit for an actuating magnet is closed, which in turn controls the clipping device in the sense of the release.
  • Both options for releasing the latching are generally provided for these circuit breakers and are activated on site according to the customer's ideas if necessary.
  • the object on which the invention is based is to reduce the variety of parts for realizing such releases of the latching devices for the circuit breakers
  • the switching device is equipped with a pushbutton which has an actuating rod in the pressure direction with a probe head corresponding to half the cross-sectional dimension of the actuating rod, 1.2.
  • the switching device contains an unlocking lever such that the probe head does not come into engagement with the unlocking lever when moving in the printing direction of a first switching position and that the probe head is in engagement with the unlocking lever when moving in the printing direction in a second switching position,
  • the actuating rod is provided in the region of the push button with a transverse pin arranged at right angles to its longitudinal axis, the free ends of which protrude equally beyond the outer contour of the actuating rod, 1.4. the transverse pin is in the first and in the second switching position via a rocker arm in such a way with a pressure switch in conjunction that Freely connectable Kon ⁇ contacts of the pressure switch actuated are achieved.
  • the switching device is equipped with an anti-rotation device in which the transverse pin is positively guided in a longitudinal slot in the first and in the second switching position.
  • the function of the cross pin is thus used in two ways; on the one hand, an anti-rotation protection of the actuating rod is achieved with the anti-rotation device with the slot width of the cross pin, since it can only be moved in the pressure direction in the two positions offset by 180 ° to release the latching device.
  • the cross pin serves to drive the rocker arm and thus to actuate the pressure switch.
  • FIG. 1 showing the switching position of the actuating rod for electrical release in addition to the parts acting on the actuating device
  • FIG. 2 shows the switching position of the actuating rod for mechanical release is indicated.
  • the actuating device BE is shown in part, which connects the latching device VE with the unlocking device.
  • lever EH contains.
  • the operating rod BS can be used in the switching position S2 (FIG. 2) by pressing the button TA in the pressure direction DR for the mechanical release of the locking device VE.
  • the actuating rod BS contains the transverse pin QS, which is guided in the anti-rotation device VS through a longitudinal slot, not shown. With this anti-rotation device VS it is achieved that the actuating rod BS can only be actuated in two switching positions S1 and S2 offset by 180 °, the switching position S1 indicating the electrical release of the latching device VE.
  • the rocker arm KH is moved in the arrow direction with the transverse pin QS, and the pressure switch DS is thus actuated.
  • Freely switchable contacts are provided within the pressure switch DS, with the aid of which an electromagnet (not shown) can be switched, which, in a manner similar to the probe TK of the actuating rod BS in the switching position S2 (FIG. 2), is applied to the unlocking lever EH Latching device VE acts.
  • the change between the electrical and the mechanical release takes place only by a switching position S2 changed by 180 ° about the longitudinal axis LA of the actuating rod BS compared to its first switching position S1.
  • FIG. 2 shows the actuating rod BS, the probe TK of which is rotated by 180 ° about the longitudinal axis LA relative to the electrical release in the switching position S1 (FIG. 1), so that with the switching position S2 the mechanical release of the latching device VE (FIG. 1) is controllable.

Abstract

L'invention concerne un dispositif d'actionnement pour interrupteur de puissance, comprenant un dispositif à encliquetage permettant de dégager l'interrupteur d'un première position pour le transférer en une deuxième position, ce dégagement pouvant être commandé méchaniquement ou électriquement. Une tige d'actionnement (BS) est munie d'une tête de palpeur (TK) d'une dimension inférieure à la moitié de sa section transversale, et au moyen de laquelle un levier de déverrouillage (EH) est actionné, ou non actionné, en deux positions de commutation, cependant qu'un interrupteur à pression (DS) peut être actionné en deux positions par l'intermédiaire d'un culbuteur (KH). Des dispositifs d'actionnement de ce type sont utilisés pour la commande d'interrupteurs de puissance dans des installations de moyenne puissance.
