    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, Α Σ ) der Verengung der Kontakttulpe (20) und einer im Abströmabschnitt (43) angeordneten dritten Verengung ist grösser als der Strömungsquerschnitt (A n ) der ersten Verengung (42), wobei durch die Verengung der Kontakttulpe (20) eine erste Teilströmung (L 11 ) einer Löschgasströmung (L 1 ) und durch die dritte Verengung eine parallel zur ersten Teilströmung (L 11 ) gerichtete zweite Teilströmung (L 12 ) 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.

    Abstract: The gas-insulated high-voltage switchgear includes a contact arrangement that is enclosed in a housing (10) and has two arc contacts in a coaxial arrangement, namely a tulip contact (20) with a constriction and a contact pin (30), said contacts being movable relative to each other along an axis (A). The switchgear also includes two insulating nozzles (40, 50) which are held at a distance to each other in the axial direction. The first (40) of the two insulating nozzles has a first flow channel (41), which is led along the axis and which comprises a first constriction (42), and the second (50) has a second flow channel (51), which is led along the axis and which has a second constriction (52). In the switchgear, the tulip contact (20) is arranged in a first flow channel (41) outflow section (43) which is arranged downstream of the first constriction (42). The sum of the flow cross-sections (Ακ, Α
    Σ ) of the constriction of the tulip contact (20) and of a third constriction arranged in the outflow section (43) is greater than the flow cross-section (A
    n ) of the first constriction (42), wherein a first sub-flow (L
    11 ) of a quenching gas flow (L
    1 ) can be conducted through the constriction of the tulip contact (20), and a second sub-flow (L
    12 ) which is oriented parallel to the first sub-flow (L
    11 ) can be conducted through the third constriction. In this manner, the dielectric restoration of an isolating gap which can be found in the arc zone (L) is improved upstream of the tulip contact (20), and the breaking capacity and the operating reliability of the switchgear are thus increased.
