Abstract

Dieser Leistungsschalter weist mindestens eine mit einem isolierenden Medium gefüllte, zylindrisch ausgebildete, entlang einer zentralen Achse (2) erstreckte, eine Leistungsstrombahn aufweisende Löschkammer, mit zwei feststehenden, auf der zentralen Achse (2) angeordneten, voneinander in axialer Richtung beabstandeten, in der Leistungsstrombahn angeordneten Abbrandkontaktanordnungen (5,6) auf. Die Abbrandkontaktanordnungen (5,6) werden im eingeschalteten Zustand elektrisch leitend verbunden durch einen beweglichen Überbrückungskontakt. Zwischen den feststehenden Abbrandkontaktanordnungen (5,6) ist eine Lichtbogenzone (24) vorgesehen. Die beweglichen Nennstromkontakte sind über mindestens ein Hebelgestänge mit dem Überbrückungskontakt verbunden, wobei das Hebelgestänge so ausgelegt ist, dass die Nennstromkontakte stets mit einer kleineren Geschwindigkeit als der Überbrückungskontakt beweglich sind.This circuit breaker has at least one with one insulating medium filled, cylindrical, extending along a central axis (2), one Arcing chamber with power circuit, with two fixed, arranged on the central axis (2), spaced from each other in the axial direction in the Power current path arranged erosion contact arrangements (5.6). The erosion contact arrangements (5,6) are in the switched on state electrically connected by a movable bypass contact. Between fixed erosion contact arrangements (5,6) is one Arc zone (24) provided. The moveable Nominal current contacts are connected via at least one lever linkage connected to the bridging contact, the lever linkage is designed so that the rated current contacts always with a lower speed than the bypass contact are mobile.

Dank dieser Anordnung kann der Leistungsschalter sehr preisgünstig und mit einer vergleichsweise grossen Dauerstandfestigkeit ausgeführt werden.

Figure 00000001
Thanks to this arrangement, the circuit breaker can be designed very inexpensively and with a comparatively high fatigue strength.
