Abstract

Der Leistungsschalter ist mit mindestens einer mit SF6-Gas, gefüllten, rotationssymmetrisch ausgebildeten, entlang einer Längsachse (3) erstreckten Löschkammer (2) versehen. Die Löschkammer (2) weist eine Leistungsstrombahn mit einem zentralen Schaltstift (14) und eine separate, mit Nennstromkontakten (11) versehene Nennstrombahn auf. Die Löschkammer (2) wird mit einem Antriebsgestänge (4) betätigt, welches den Schaltstift (14) und die Nennstromkontakte (11) bewegt. Das Antriebsgestänge (4) ist so ausgelegt, dass am Beginn des Ausschaltvorgangs der Schaltstift (14) solange in einer ersten Totpunktstellung verbleibt, bis die Nennstrombahn unterbrochen ist. Der Schaltstift (14) ist danach mit einer wesentlich höheren Geschwindigkeit in die Ausschaltrichtung bewegbar als die Nennstromkontakte (11). Die Nennstromkontakte (11) laufen gegen Ende ihres Ausschalthubes in eine zweite Totpunktstellung ein. Der Schaltstift (14) erreicht erst nachdem die Nennstromkontakte (11) ihre Ausschaltbewegung beendet haben seine Ausschaltstellung. Bei Beginn des Einschaltvorgangs verbleiben die Nennstromkontakte (11) solange in dieser zweiten Totpunktstellung, bis die Vorzündung des Einschaltlichtbogens erfolgt ist. Die Nennstromkontakte (11) werden auf diese Art vorteilhaft vor Beschädigungen durch einen Lichtbogen geschützt.

Figure 00000001
The circuit breaker is provided with at least one quenching chamber (2) which is filled with SF 6 gas and is rotationally symmetrical and extends along a longitudinal axis (3). The arcing chamber (2) has a power current path with a central switching pin (14) and a separate nominal current path provided with nominal current contacts (11). The quenching chamber (2) is operated with a drive linkage (4) which moves the switching pin (14) and the nominal current contacts (11). The drive linkage (4) is designed so that at the beginning of the switch-off process, the switching pin (14) remains in a first dead center position until the rated current path is interrupted. The switching pin (14) can then be moved in the switch-off direction at a significantly higher speed than the rated current contacts (11). The rated current contacts (11) run into a second dead center position towards the end of their switch-off stroke. The switching pin (14) only reaches its switch-off position after the rated current contacts (11) have completed their switch-off movement. At the start of the switch-on process, the nominal current contacts (11) remain in this second dead center position until the switch-on arc has pre-ignited. In this way, the nominal current contacts (11) are advantageously protected against damage by an arc.
