Abstract

La présente invention concerne un module à contacts mobiles rotatifs à doubles points d'ouverture. Il comprend un rotor monobloc en forme de barre (101), une première barre de connexion (102), une seconde barre de connexion (103), et un arceau de contacts (104). Le rotor monobloc en forme de barre (101) est indépendant de chacune des phases. Un premier trou traversant (110) est ménagé au centre du rotor monobloc en forme de barre (101), un premier axe (105) étant monté dans ce trou. Chaque face latérale de l'axe du rotor monobloc en forme de barre (101) comporte un premier évidement (111). Des ressorts de contacts (108) sont montés dans le premier évidement (111). Ils sont mobiles dans les limites de la plage définie par le premier évidement (111). La première barre de connexion (102) est montée sur le rotor monobloc en forme de barre (101). Le deuxième axe (106) pénètre au travers de la première barre de connexion (102). Le deuxième axe (106) et le troisième axe (107) pénètrent chacun au travers de la seconde barre (103). L'arceau de contacts (104) est conçu pour pénétrer au travers du rotor monobloc en forme de barre (101). Le profil extérieur de l'arceau de contacts (104) présente une symétrie centrale. Le premier axe (105) et le troisième axe (107) pénètrent chacun au travers de l'arceau de contacts, des points de contact étant soudés sur les points d'extrémité des faces latérales. Ce module à contacts mobiles rotatifs à doubles points d'ouverture est capable de fermer et d'ouvrir le porte-contact mobile quand se produit un gros court-circuit. En outre il s'ouvre rapidement et ne se referme pas par rebond. Enfin, il maintient l'équilibre des pressions entre deux points de contact.
