Background

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.

A circuit breaker generally includes a contact system, an arc extinguishing system, an operating mechanism, a trip unit, a case, and the like. When short circuit occurs, a magnetic field generated by large current (generally 10 to 12 times) overcomes a counterforce spring, a release pulls an operating mechanism to act, and a switch is tripped instantaneously. When the overload occurs, the current becomes large, the heating value becomes large, and the bimetallic strip deforms to a certain degree to push the mechanism to act (the larger the current is, the shorter the acting time is).

Because the circuit breaker has higher requirements on safety when in use, the quality of the circuit breaker is strictly checked in the process of producing the circuit breaker, and each link of the circuit breaker is strictly checked to avoid the problems of short circuit and failure of the circuit breaker in the use process.
