Abstract

Dispositif de coupure électrique à contact auxiliaire Dispositif de coupure électrique comportant un fusible utilisé pour ouvrir une ligne de puissance dans laquelle circule un courant continu, un tiroir mobile (16B, 34, 36) relié au fusible et susceptible, une fois le fusible rompu, de se déplacer dans une chambre fixe (22 ; 22A) sous l’action d’un ressort de compression monté entre la chambre fixe et le tiroir mobile, et un contact auxiliaire dont une partie de contact fixe (320A, 320B) est solidaire de la chambre fixe et une partie de contact mobile (322A, 322B) solidaire du tiroir mobile dont le déplacement va entrainer l’ouverture du contact auxiliaire normalement fermé. Figure pour l’abrégé : Fig. 3.
