Abstract

Die Erfindung betrifft einen Lasttrennschalter mit Federkraftantrieb zum Betätigen wenigstens eines Schaltkontaktes, insbesondere von Mittelspannungsanlagen in einem Bereich bis 24 kV, mit wenigstens einer Einschalt- und wenigstens einer Ausschaltfeder, einer Schalterwelle, an der der Federkraftantrieb für die Schaltbewegung angreift und die den wenigstens einen Schaltkontakt trägt.The invention relates to a switch-disconnector with spring drive for actuating at least one switching contact, in particular medium-voltage systems in a range up to 24 kV, with at least one switch-on and at least one opening spring, a switch shaft to which the spring drive for the switching movement engages and the at least one switching contact wearing.

Die Erfindung zeichnet sich dadurch aus, dass eine Blockiereinrichtung für den Federkraftantrieb vorgesehen ist, die diesen vor Erreichen der Totpunkt-stellung der Einschaltfeder in einer gespannten Lage hält.

Figure imgaf001
The invention is characterized in that a blocking device is provided for the spring force drive, which keeps this before reaching the dead center position of the closing spring in a tensioned position.
