Background
A circuit breaker refers to a switching device capable of closing, carrying and opening a current under normal circuit conditions and closing, carrying and opening a current under abnormal circuit conditions within a prescribed time. The circuit breaker is divided into a high-voltage circuit breaker and a low-voltage circuit breaker according to the application range, and the division of a high-voltage boundary line and a low-voltage boundary line is fuzzy, and is generally called as a high-voltage electrical appliance with the voltage of more than 3 kV. The circuit breaker can be used for distributing electric energy, starting the asynchronous motor infrequently, protecting a power line, the motor and the like, and automatically cutting off the circuit when serious overload or short circuit, undervoltage and other faults occur, and the functions of the circuit breaker are equivalent to the combination of a fuse type switch, an over-under-heating relay and the like. And the parts are not required to be changed after breaking the fault current. A wide range of applications have been achieved. During the use process of the intelligent circuit breaker, the mechanism is always in the pre-energy storage position, and the circuit breaker can be immediately and instantaneously closed as long as the circuit breaker receives a closing command.
