Abstract

Die Erfindung betrifft eine Anordnung zur selektiven Auslösung von hintereinander geschalteten, selektiv gestaffelten Schutzschaltern mit einem eine Verklinkungseinrichtung enthaltenden Betätigungsmechanismus, wobei ein vom Kurzschluss direkt betroffener Schutzschalter ein Blockiersignal an den Betätigungsmechanismus bzw. das Auslösesystem des vorgeschalteten Schutzschalters ausgibt. Das zu lösende Problem besteht in einer von Vorgängen im Kontaktraum des Schutzschalters unabhängigen und unaufwendigen Erzeugung eines Blockiersignals. Dazu ist für jede Hauptstrombahn ein elektromagnetischer Kurzschlussauslöser (4) vorgesehen, dessen Magnetanker (6) mit einem Kontaktelement (14a) in Wirkverbindung steht, das an dem Einstellelement (7) für den Kurzschlussauslöser (4) angeordnet ist.

Figure 00000001
The invention relates to an arrangement for the selective triggering of series-connected, selectively staggered circuit breakers with an actuating mechanism containing a latching device, wherein a circuit breaker directly affected by the short circuit outputs a blocking signal to the actuating mechanism or the triggering system of the upstream circuit breaker. The problem to be solved consists in the fact that a blocking signal is generated in an independent and uncomplicated manner from processes in the contact space of the circuit breaker. For this purpose, an electromagnetic short-circuit release (4) is provided for each main current path, the magnet armature (6) of which is operatively connected to a contact element (14a) which is arranged on the setting element (7) for the short-circuit release (4).
