auxiliary switch for SF6 circuit breaker

auxiliary switch for SF6 circuit breaker 1. Main application This series applies to the HV operating mechanisms switching on, switching off, interlock, and controlling of signal circuit. It also applies to HV switchgears, and can be used as transfer switch or cubicle switch. F11 series is direct driving type, and each layer contains one pair of static contacts. The contacts are of two kinds: one is timelag, another is not. Delay contacts can countervail the operative time lag of TBJ, and instantaneous contacts resolve the problem that electronic parts are often burned out as they are electriferous for a long time. Its totally enclosed type, and applies to severe atmosphere. 2.
