Abstract

Die vorliegende Erfindung hat eine Lichtbogenlöscheinrichtung für Schutzschalter mit Doppelunterbrechung zum Einsatz in Niederspannungsverteilnetzen zum Gegenstand. In den Lichtbogenlöschkreis ist eine asymmetrische Blasschlaufe (81) eingeführt, welche parallel zu einer Lichtbogenlaufschiene einen Lorentzabschnitt (811) zur Verstärkung der magnetischen Blaswirkung auf einen Lichtbogen umfasst. Bevorzugte Ausführungsformen betreffen eine abschaltstrombegrenzende Eigenschaft der Blasschlaufe und eine magnetische Abschirmung der Lichtbogenleitstrecke.

The present invention relates to an arc quenching device for double-breaker circuit breakers for use in low-voltage distribution networks. In the arc extinguishing circuit, an asymmetric blown loop (81) is inserted, which comprises a Lorentz section (811) parallel to an arc runner for amplifying the magnetic blowing effect on an arc. Preferred embodiments relate to a turn-off current limiting property of the blown loop and a magnetic shield of the arc guide.
