The circuit breaker is a switching device capable of closing, carrying, and opening/closing a current under a normal circuit condition and a current under an abnormal circuit condition within a prescribed time. The circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to the application range, the high-voltage and low-voltage boundary lines are relatively vague, and the circuit breakers above 3kV are generally called high-voltage electric appliances. The circuit breaker can be used for distributing electric energy, starting an asynchronous motor infrequently, protecting a power supply circuit, the motor and the like, and automatically cutting off a circuit when faults such as serious overload, short circuit, undervoltage and the like occur, and the function of the circuit breaker is equivalent to the combination of a fuse type switch, an over-under-heat relay and the like. Furthermore, no parts need to be changed after breaking the fault current. At present, it has been widely used. Distribution of electricity is an extremely important link in the generation, transmission and use of electricity. The distribution system comprises a transformer and various high-low voltage electrical equipment, and the low-voltage circuit breaker is an electrical appliance with a large using amount.
