Abstract

Die Erfindung betrifft eine Drosselspule, deren Induktivität oberhalb eines gegebenen Strombereichs bei steigendem Strom zunimmt. Sie besteht darin, daß innerhalb oder außerhalb der Wicklung der Drosselspule ein ferromagnetischer Hohlkörper angeordnet ist. Der Hohlkörper ist so dimensioniert, daß er den Innen- bzw. Außenraum bis zu einem bestimmten Strom, der in der Wicklung fließt, magnetisch abschirmt. Bei stark erhöhtem Strom, wie dies im elektrischen Netz beim Übergang vom Nennstrom zum Kurzschlußstrom vorkommt, geht die abschirmende Wirkung auf einen Bruchteil des anfänglichen Werts zurück, so daß der von der Wicklung erzeugte magnetische Fluß nicht mehr abgeschirmt wird und die Induktivität der Anordnung ansteigt.
