Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung (1) zur Strombegrenzung sowie eine Schaltanlage mit einer solchen Vorrichtung (1). Erfindungsgemäss wird Flüssigmetall (3) entlang eines Widerstandselements (5) für den Strombegrenzungspfad (31) geführt, um eine lichtbogenfreie Strombegrenzung für netzbedingte Kurzschlussströme (i(t)) zu erzielen. Ausführungsbeispiele betreffen u.a.: einen in der Bewegungsrichtung (x) des Flüssigmetalls (3) nicht­ linear zunehmenden elektrischen Widerstand (Rx) für eine sanfte Strombegrenzungscharakteristik, ein Widerstandselement (5) in Form einer dielektrischen Matrix (5) mit Kanälen (3a) für das Flüssigmetall (3), und ein kombinierter Strombegrenzer-Leistungsschalter (1). Vorteile sind u. a.: lichtbogenfreie, reversible Strombegrenzung und gegebenenfalls Stromabschaltung, geeignet auch für hohe Spannungen und Ströme, schnelle Reaktionszeiten, geringer Verschleiss und wartungsfreundlich.
