The high-voltage circuit breaker is used for controlling a high-voltage circuit and is one of important electrical components in the high-voltage circuit. The circuit breaker is used for switching on or off a circuit in normal operation, and a fault condition rapidly breaks the circuit under the action of a relay protection device and reliably switches on short-circuit current under special conditions (such as automatic reclosing on a fault line). A high-voltage circuit breaker is a special appliance that switches on or off a high-voltage circuit under normal or fault conditions.
