Abstract

Bei Druckgas-Leistungsschaltern besteht das Problem, die für die Führung des Nennstromes und des Kurzschluß­ stromes vor dem Öffnen des Kontaktsystems bestimmten Hauptstrombahnen vor Lichtbogeneinwirkungen zu schüt­ zen. Insbesondere Kontaktsysteme mit einem düsenförmi­ gen feststehenden Schaltstück (4), mit einem zweiten gleich­ achsig angeordneten düsenförmigen, axial beweglichen Schaltstück (5) und einem beiden gemeinsamen bewegli­ chen Überbrückungsschaltstück (6) sollen die für die Nenn­ stromübertragung vorgesehenen Kontaktelemente (6a) des Überbrückungsschaltstückes (6) an der Führung des Lichtbo­ gens nicht teilnehmen, um eine Erhöhung der dielektrischen Festigkeit der Trennstrecke (T) zu erzielen. Hierzu liegt das zweite Schaltstück (5) in der Einschaltstellung unter Feder­ kraft stirnseitig am ersten Schaltstück (4) an. Im Verlauf des Ausschaltvorganges wird durch das vom ersten Schaltstück (4) ablaufende Überbrückungsschaltstück (6) das zweite Schaltstück (5) verzögert in die Trennstellung (T) überführt. Der gezogene Lichtbogen wirkt nur zwischen dem ersten und dem zweiten Schaltstück, (4 und 5), das mit abbrandfesten Graphitelektroden ausgestattet werden kann.
