Abstract

L'invention concerne de nouveaux interrupteurs à vide capables d'exécuter les fonctions 'commutation', 'isolation' et 'mise à la terre' et pouvant être fabriqués de façon économique. A cet effet, un premier système de protection à contacts (22), conçu à partir de contacts à champ magnétique axial ou radial (21, 23), présente un contact mobile (21) relié au contact mobile (26, 27) d'un deuxième système de protection (25) à contacts constitué de disques annulaires (16, 27). Le contact fixe (13) du deuxième système de protection à contacts forme une partie annulaire du boîtier (10) auquel sont connectés deux isolateurs tubulaires (11, 12). Un (11) des isolateurs, qui entoure les deux systèmes à contacts (22, 25), est protégé par un blindage (31) fixé à la pièce de contact mobile (21, 26) et isolant ces deux systèmes de protection à contacts du point de vue de la physique des plasmas.
