    摘要： Die vorliegende Erfindung betrifft eine Schaltvorrichtung, insbesondere für Mittelspannungsschaltanlagen, mit einer gekapselten, ein Löschgas enthaltenden Schaltkammer 13, mit einem ersten Kontakt 2 und einem zweiten Kontakt 4, die in der Schaltkammer 13 angeordnet sind, wobei mindestens der erste Kontakt relativ zum zweiten Kontakt beweglich ist und die Kontakte miteinander verbunden oder voneinander getrennt werden können, und mit einer Beblasungseinrichtung, die eine Düseneinrichtung mit zumindest einer Düse aufweist, zum Beblasen eines Bereichs, in dem sich beim Trennen der Kontakte ein Schaltlichtbogen ausbildet, mit dem Löschgas. Um eine derartige Schaltvorrichtung mit verbesserten Lichtbogenlöscheigenschaften bereitzustellen, weist sie mindestens ein relativ zu den Kontakten bewegliches Düsenelement 19 auf, das zumindest teilweise die Düse bildet, wobei die Beweglichkeit des Düsenelements mindestens durch einen Anschlag 15a begrenzt ist.

    摘要： A circuit breaker which includes at least one quenching chamber is described. The quenching chamber is configured to be filled with insulating gas, extends along a longitudinal axis and includes an arcing zone and an exhaust zone. The exhaust zone is configured to dissipate hot insulating gases from the arcing zone into an exhaust tank. At least one deflection volume is enclosed by a deflection housing and is arranged within an inner volume of the exhaust zone. The at least one deflection volume is configured to fluidly connect the arcing zone with the exhaust tank through a plurality of openings within the deflection housing.
