The invention provides a system and a method for monitoring the stroke of a circuit breaker contact. The system comprises a metal target, a PCB coil, a measuring chip and a controller; the metal target is arranged on a main shaft of the circuit breaker to be monitored or below the insulating pull rod; the PCB coil and the plane of the metal target are arranged in parallel, and the PCB coil and themetal target are not in contact with each other; the measuring chip is connected with the PCB coil and used for monitoring a resonance signal of the PCB coil and obtaining an inductance value based on the resonance signal when the relative position of the metal target and the PCB coil moves due to the action of the circuit breaker main shaft or the insulating pull rod; the controller is connectedwith the measuring chip and used for receiving the inductance value sent by the measuring chip and determining the stroke of the circuit breaker contact. The system and the method for monitoring thestroke of the circuit breaker contact solves the problems of sensor installation and electromagnetic interference in the circuit breaker contact stroke monitoring system through a non-contact measurement technology.
