Definitions

  • the invention relates to a switching device unit with a switching device with a first actuating element and with a leading auxiliary switch coupled to the switching device with a second actuating element.
  • a generic switchgear unit is available from switchgear manufacturers.
  • the switching device is a circuit breaker, on the edge of which a rocker switch is installed as an actuating element.
  • the rocker toggle allows you to grasp the rotary toggle of an undervoltage release with a leading auxiliary switch.
  • the rotary knob is provided with a leading play, so that the leading auxiliary switch is first switched on before the circuit-breaker starts.
  • the axes of rotation of the rocker switch of the circuit breaker and of the rotary switch of the leading auxiliary switch lie on one line.
  • the invention has for its object to provide a switching device unit of the type mentioned above, which is characterized by a simple switch-on process with only one hand movement if possible.
  • the second actuating element is designed as a slide with a link which is in engagement with a bell crank and which, when the slide is actuated, determines the position of the bell crank in such a way that the bell crank is a contact carrier in operative connection with it brings the first actuation phase of the slide in the ON position of movable contacts with fixed contacts of the leading auxiliary switch and in a subsequent second actuation phase of the slide
  • the ON position of the bell crank is maintained and at the same time the slide actuates the first actuating element.

Abstract

Selon l'invention, le commutateur auxiliaire (2) présente comme élément d'actionnement une glissière (5) avec une coulisse (14) qui coopère avec un levier de renvoi (13) agissant sur le porte-contacts (11). Après une première phase d'actionnement, dans laquelle la glissière (5) fait passer le porte-contacts (11) en position MARCHE, l'élément d'actionnement d'un appareil de commutation de base (1) est actionné par une nouvelle pression.
