Abstract

Einstufig betätigbarer Stufenwähler für Stufentransformatoren, bei dem die feststehenden Stufenkontakte einer Phase in zwei Ebenen am Umfang des Zylinders angeordnet sind und bei dem ein zentrales Schaltrohr vorgesehen ist, das in jeder Ebene einen beweglichen Kontakt führt und das mittels einer an seinem oberen Ende sitzenden Antriebsscheibe, in die eine Antriebskurbel mit zwei um 180° versetzten Nocken wechselseitig eingreift, schrittweise betätigbar ist. Der Stufenwähler besitzt einen nach vollen Umlauf betätigbaren Vorwähler, der fluchtend unterhalb des Stufenwählers angeordnet ist, wobei dessen Kontakte in einer weiteren Ebene des zylindrischen Stufenwählers liegen und dessen bewegliche Kontakte in Abhängigkeit vom Antrieb der Kontakte des Stufenwählers betätigbar sind. Hierbei sitzen die beweglichen Vorwählerkontakte (30) am Ende einer konzentrisch im Schaltrohr (21) angeordneten Schaltwelle (31), wobei die Schaltwelle mittels einer an ihrem oberen Ende sitzenden Kurbel (32) in Abhängigkeit von der Antriebsscheibe (28) des Stufenwählers betätigbar ist.
