Abstract (en)
The device has a vacuum cartridge (6) branch-connected with line-side and load-side stationary contacts (1, 2) and a rotating/sliding main movable contact (3) of a main electric circuit. The cartridge has a rod (10) passing via an enclosure (7) and supporting a movable contact (9) of the cartridge. A vacuum cartridge operating mechanism is actuated by the main contact, and actuates the rod. The mechanism has a rigid rotating rocker arm (12) connecting the rod and the main contact. The arm has articulation regions around which the arm is rotated during opening and closing operations of circuit.
Abstract (fr)
Ce dispositif de coupure de courant comprend, comme mécanisme de commande d'une ampoule à vide (6) en dérivation sur une circuit principal (1, 2, 3) à un contact principal mobile (3), un balancier (12) interceptant le contact principal mobile (3) pendant l'ouverture ou la fermeture de l'appareil et tournant pour ouvrir l'ampoule à vide tout en établissant une liaison électrique ; ce balancier est unitaire et rigide et peut tourner autour de deux points d'articulation (11, 21), l'un actif pendant les ouvertures et l'autre pendant les fermetures, pour alors permettre d'escamoter le balancier, qui, unitaire, est plus robuste.
