Abstract

Es wird ein einfacher und kostengünstig herstellbarer Schnellschalter für abzuschaltende Wechselströme angegeben, der mittels einer gaserzeugenden Sprengladung (4) innerhalb einer Halbschwingung beim Nulldurchgang des Stromes diesen abschaltet. Dabei wird ein Schaltkolben (2), der im Schließzustand des Schnellschalters mit einem Abbrandkontaktstift (K1) einer 1. Elektrode (E1) in Gleitkontakt steht, in Richtung einer Hohlelektrode (E2) bewegt. Der Schaltkolben (2) weist ein Kontaktrohr (2') mit einer Auspufföffnung (3) auf, welche im Schließzustand des Schnellschalters durch die Hohlelektrode (E2) verschlossen und in einem Öffnungszustand des Schnellschalters (linke Bildhälfte) zu einer Auspuffkammer (8) hin geöffnet ist. Das Kontaktrohr (2') ist in einer Aussparung der Hohlelektrode (E2) gleitend beweglich. In der 1. Elektrode (E1) können mehrere Sprengladungen (4) untergebracht sein. Zusätzlich können zwischen der 1. Elektrode (E1) und dem Schaltkolben (2) vorgesehene Nennstromkontakte einen Dauerstrom im eingeschalteten Zustand übernehmen. Der Schnellschalter eignet sich besonders als zusätzlicher Schalter zu einem Leistungsschalter, wobei eine Auslösung des Schnellschalters unabhängig von einem Auslösesignal für den Leistungsschalter erfolgen kann.
