Abstract

Die Erfindung betrifft eine Antriebsvorrichtung für einen Niederspannungs-Leistungsschalter (10) zum Hin- und Wegbewegen eines an einem drehbar gelagerten Kontaktträger (16) angeordneten beweglichen Kontaktes (14) zu oder von einem festen Kontakt (12), wobei der Kontaktträger (16) mit einer Schaltwelle (20) verbunden ist, welche durch mindestens zwei drehbeweglich gelagerte Verbindungselemente (22, 26) mit einem Kraftspeicher (36) verbunden ist, wobei die zwei Verbindungselemente (22, 26) eine gemeinsame Drehachse (38) aufweisen und dort mit mindestens einer Zuglasche (24a, 24b, 24c) verbunden sind, welche an einem festen Punkt (42) drehbeweglich gehalten ist. DOLLAR A Es ist vorgesehen, dass die Zuglasche mindestens drei starre Glieder (24a, 24b, 24c) aufweist, wobei das erste starre Glied (24a) der Zuglasche drehbeweglich um die gemeinsame Drehachse (38) angeordnet und mit den zwei Verbindungselementen (22, 26) verbunden ist und mit dem zweiten starren Glied (24b) und dem dritten starren Glied (24c) der Zuglasche drehbeweglich verbunden ist, wobei alle Glieder (24a, 24b, 24c) eine gemeinsame Drehachse (40) aufweisen und das zweite Glied (24b) und das dritte Glied (24c) der Zuglasche jeweils drehbeweglich an einem festen Haltepunkt (42, 44) gehalten sind.
