General breaker run (1) operating current, the maximum operating voltage does not exceed the rated breaking current. (2) In order to avoid close in on the point of failure, causing an explosion endangering personal safety breaker Ningbo high-voltage vacuum circuit breakers, the absolute prohibition of manual mechanical closing Taizhou charged voltage vacuum circuit breaker, or manual operation of the circuit breaker button to switch on the spot. (3) the operation of the circuit breaker, prohibiting manual mechanical or manual push button opening, when the remote control failure or too late when the remote control can operate. Automatic reclosing, automatic reclosing function should be lifted. (4) one of the following circumstances, should a power outage overhaul: abnormal noise and severe fever; after accident trip, fuel injection is serious, oil blackened; breaking a short circuit interrupting capacity exceeded; breaking the fault current exceeds predetermined times; gas pressure or oil level is below the specified value. (5) prohibits the defective circuit breaker into operation. (6) indicates that, to demonstrate compliance with the circuit breaker operation. (7) that the auxiliary switch contact status and operating environment. Welcome to inquire buy! I vacuum arc and gas arcing great difference Suzhou voltage vacuum circuit breaker, the phenomenon of free gas is not the main factor of the arc, vacuum arc discharge is in the contact electrode evaporated metal vapor formed. At the same time, the size of the different breaking current arc performance characteristics are also different. We usually divide it into small current vacuum arc and large current vacuum arc.
