Common Faults In Electrical Circuits Some Reasons For The Operating Mechanism Of Sf6 Circuit Breakers

If the red and green indicator lights are off before the closing operation, it means that the control circuit is disconnected or there is no control power supply (such as the control fuse is broken). You can check whether the control power supply and each component on the entire sf6 circuit breaker operating mechanism control circuit are normal, such as whether the operating voltage is normal, whether the fuse is blown, whether the anti-trip relay is normal, whether the sf6 circuit breaker spring mechanism auxiliary contacts are in good condition, and whether there is any pressure reduction lockout, etc.
