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.
