The high-voltage circuit breaker is one of the most important equipment in the power system. It is used to switch on and off the circuit under normal conditions and can quickly break the fault current in the event of a fault. include: Cut off or close the no-load current of the high-voltage line; Cut...

The high-voltage circuit breaker (or high-voltage switch) can not only cut off or close the no-load current and load current in the high-voltage circuit, but also cut off the overload current and short-circuit current through the function of the relay protection device when the system fails. The perf...
