Abstract

Die Erfindung betrifft einen Schubtrennschalter (1) mit zwei Stützisolatoren (3, 4) und einem im eingeschalteten Zustand die Stützisolatoren (3, 4) elektrisch verbindenden Schaltmesser (5), welches an seinem in der Einschaltbewegung vorderen Ende eine Kontaktanordnung (52) zur Kontaktierung eines feststehenden Kontakts (32) des ersten Stützisolators (3) aufweist, und im Bereich seines in Einschaltrichtung hinteren Endes am zweiten Stützisolator (4) in einer Führungseinrichtung (7) beweglich geführt ist. Der erfindungsgemäße Schubtrennschalter (1) zeichnet sich dadurch aus, daß das Schaltmesser (5) an seinem in Einschaltrichtung hinteren Ende eine Kontaktanordnung (53) trägt, deren Kontaktelemente in Richtung zum zweiten Stützisolator (4) weisen, wobei die Kontaktanordnung (53) im eingeschalteten Zustand von der in Einschaltrichtung hinteren Seite her einen feststehenden Kontakt (42) des zweiten Stützisolators (4) kontaktiert und bei der Ausschaltbewegung von diesem entfernt wird. Damit wird ein Schubtrennschalter erzielt, mit dem im Vergleich zu herkömmlichen Schubtrennschaltern höhere Kurzschlußstromstärken geführt werden können.

The invention relates to a push-disconnect switch (1) with two support insulators (3, 4) and a switched-in state, the support insulators (3, 4) electrically connecting switch blade (5), which at its front end in the closing movement of a contact assembly (52) for contacting a fixed contact (32) of the first support insulator (3), and is movably guided in the region of its rear end in the switching direction on the second support insulator (4) in a guide device (7). The thrust disconnector switch (1) according to the invention is characterized in that the switch blade (5) carries at its rear end in the switch-on a contact assembly (53) whose contact elements in the direction of the second post insulator (4), wherein the contact assembly (53) in the switched Condition of the rear side in the switch-on direction a fixed contact (42) of the second post insulator (4) is contacted and removed during the turn-off movement of this. Thus, a push-break switch is achieved, with which higher short-circuit currents can be performed compared to conventional push-breakers.
