Abstract

L'invention concerne un disjoncteur à vide à dispositif de maintien de fermeture. Une cavité creuse est formée dans une enceinte (9) ; des ressorts d'arrêt (6) sont chemisés sur un pôle conducteur mobile (3) et agencés au milieu de la cavité dans l'enceinte ; un contact mobile (7) est connecté avec une tige supérieure de la partie supérieure du pôle conducteur mobile ; un contact statique (8) est fixé en haut de la cavité et est séparée du contact mobile ; des cliquets de maintien de fermeture (1) sont agencés sur la partie inférieure du pôle conducteur mobile par paires ; des ressorts de pression (2) sont agencés entre des parties latérales des extrémités inférieures des cliquets de maintien de fermeture et la paroi intérieure de la cavité ; des excroissances sont agencées au niveau des parties centrales des cliquets de maintien de fermeture et serrées sur le bas du pôle conducteur mobile exactement quand le contact mobile et le contact statique sont en contact ; des plans inclinés sont agencés au niveau des parties inférieures des cliquets de maintien de fermeture ; les plans inclinés d'une paire de cliquets de maintien de fermeture forment une structure en forme de V verticale ; un bloc de déverrouillage de maintien de fermeture (5) est agencé dans la structure en forme de V ; et un contact mobile commutateur d'isolation (4) est agencé au niveau de la partie inférieure du bloc de déverrouillage de maintien de fermeture de manière à pousser le bloc de déverrouillage de maintien de fermeture pour effectuer un mouvement vers le haut et le bas. Le disjoncteur à vide comportant le dispositif de maintien de fermeture est pratique à contrôler.
