Abstract (en)

The circuit breaker is held in a gas filled envelope (1) and has a contact section (2) and second contact section (3) following the longitudinal direction. There is a resistance (R) which is inserted using auxiliary sliding contacts (7A,7B). The contacts are brought into contact during switch closing.

Abstract (fr)

Dans l'interrupteur, le système d'insertion de la résistance (R) comprend deux contacts auxiliaires dont le premier (7B) est relié électriquement à un contact de courant permanent (3A) semi-mobile et le second (7A) est relié électriquement à un contact d'arc fixe (3B). Ces deux contacts auxiliaires sont montés mobiles l'un par rapport à l'autre suivant la direction longitudinale (D) de telle façon à pouvoir se rapprocher l'un de l'autre, lors de la fermeture de l'interrupteur, pour établir une connexion qui court-circuite la résistance et de telle façon à être solidaires en déplacement suivant la direction longitudinale, lors de la fermeture de l'interrupteur, avant d'établir ladite connexion qui court-circuite la résistance de telle façon à allonger la durée d'insertion de la résistance. <IMAGE>
