A group operated switching apparatus for overhead electric power lines has a box-like elongated housing which mounts on a pole and supports threedisconnect switches. Three operating shafts are journalled on the housing and are operatively connected to the disconnect switches so that axial rotation of the operating shafts alternately opens and closes the disconnect switches. An upright control shaft extends through the housing. A transverse rod assembly is enclosedwithin the housing and defines a mechanical connection between the control shaftand the operating shafts so that axial rotation of the control shaft causes axial rotation of the operating shafts. Each disconnect switch includes a jaw terminalhaving dual function backup springs and auxiliary contacts for minimizing effects of arcing during opening and closing of the switch.
Cette invention concerne un appareillage de sectionnement à commande simultanée pour lignes aériennes qui comprend un logement en forme de boîte allongée monté sur poteau et supportant trois sectionneurs. Trois arbres de commande sont montés à tourillon dans le logement et raccordés aux sectionneurs de manière que leur rotation autour de leur axe longitudinal commande alternativement l'ouverture et la fermeture des sectionneurs. Un arbre de commande vertical traverse le logement à l'intérieur duquel il est raccordé au moyen d'une bielle transversale aux arbres de commande de manière que sa rotation ait pour effet de faire tourner les arbres de commande autour de leur axe. Chaque sectionneur comporte une borne à mâchoires munie de ressorts d'appoint à fonction double et de contacts auxiliaires destinés à réduire au minimum les arcs électriques à l'ouverture et à la fermeture.
