Abstract

Die Erfindung betrifft einen metallgekapselten, gasisolierten Hochspannungsschalter, mit einer festen Kontaktanordnung (12), die in einem eigenen Festkontaktgehäuse (11) aufgenommen ist, und mit einer von einem ersten Antrieb (40) angetriebenen beweglichen Kontaktstückanordnung (13), die in einem mit der beweglichen Kontaktstückanordnung (13) verbundenen oder bei einer Schalthandlung mit dieser bewegbaren Kontaktgehäuse (21) untergebracht ist, wobei die Kontaktanordnungen ggf. Kontaktstücke für Nennstrom und für die Führung und Löschung des Lichtbogens aufweist. Dabei sind Mittel zur Erzeugung einer Gasströmung vorgesehen, die eine Isolierstoffdüse (15) umfassen, in der der Lichtbogen brennt und beblasen wird, und die in dem Festkontaktgehäuse (11) während der gesamten Schalthandlung abgedichtet geführt ist. Zur Erzielung einer Trennschalterfunktion ist ein zweiter Antrieb (48) vorgesehen, der während oder nach Beendigung der Ausschalthandlung das Festkontaktgehäuse (11) mit der festen Kontaktstückanordnung (12) entgegen der Ausschaltrichtung der beweglichen Kontaktstückanordnung (13) antreibt, so daß die Isolierdüse von ihrer Führung freikommt und dadurch eine Trennstrecke zur Erzielung einer Trennschalterfunktion erzielt ist.

The invention relates to a metal-encapsulated, gas-insulated high-voltage switch, with a fixed contact arrangement (12) which is accommodated in its own fixed contact housing (11), and with a movable contact piece arrangement (13) driven by a first drive (40), which in one with the Movable contact piece arrangement (13) or in a switching operation with this movable contact housing (21) is housed, the contact arrangements optionally having contact pieces for nominal current and for guiding and extinguishing the arc. Means for generating a gas flow are provided which comprise an insulating nozzle (15) in which the arc burns and is blown, and which is guided in a sealed manner in the fixed contact housing (11) during the entire switching operation. In order to achieve a disconnector function, a second drive (48) is provided which drives the fixed contact housing (11) with the fixed contact piece arrangement (12) against the direction of switching off the movable contact piece arrangement (13) during or after completion of the switch-off action, so that the insulating nozzle is guided by it is released and thereby a isolating distance to achieve an isolating switch function is achieved.
