Nader Circuit Breaker

Vacuum circuit breakers have many advantages such as small maintenance workload, large interrupting capacity, and suitable for frequent operation. They have gradually replaced other types of switches in power systems and have been widely used. However, the operating overvoltage problem of the vacuum ...

The operating over-voltages of vacuum circuit breakers mainly include blocking over-voltage, reignition high-frequency over-voltage, thumping through voltage, bounce-over voltage and so on. The interception overvoltage and the reignition overvoltage are generally generated when the inductive load is ...
