Abstract

Der gasisolierte Hochspannungsschalter enthält eine in einem Gehäuse (10) eingeschlossenen Kontaktanordnung, die in koaxialer Anordnung zwei längs einer Achse (A) relativ zueinander bewegliche Lichtbogenkontakte, nämlich eine Kontakttulpe (20) mit einer Verengung und einen Kontaktstift (30), aufweist sowie zwei Isolierdüsen (40, 50), die in axialer Richtung mit Abstand zueinander gehalten sind. Eine erste (40) der beiden Isolierdüsen weist einen längs der Achse geführten ersten Strömungskanal (41) mit einer ersten Verengung (42) und die zweite (50) einen längs der Achse geführten zweiten Strömungskanal (51) mit einer zweiten Verengung (52) auf. Bei diesem Schalter ist die Kontakttulpe (20) in einem stromabwärts der ersten Verengung (42) angeordneten Abströmabschnitt (43) des ersten Strömungskanals (41) angeordnet. Die Summe der Strömungsquerschnitte (Ακ, ΑΣ) der Verengung der Kontakttulpe (20) und einer im Abströmabschnitt (43) angeordneten dritten Verengung ist grösser als der Strömungsquerschnitt (An) der ersten Verengung (42), wobei durch die Verengung der Kontakttulpe (20) eine erste Teilströmung (L11) einer Löschgasströmung (L1) und durch die dritte Verengung eine parallel zur ersten Teilströmung (L11) gerichtete zweite Teilströmung (L12) führbar ist. Dadurch verbessert sich die dielektrische Wiederverfestigung einer in der Lichtbogenzone (L) befindlichen Trennstrecke stromaufwärts der Kontakttulpe (20) und werden so die Ausschaltleistung und die Betriebssicherheit des Schalters erhöht.
