A circuit breaker control method, system and circuit breaker

Abstract

The application provides a circuit breaker control method, system and circuit breaker, and belongs to the technical field of circuit breaker control. In the application, first, an action time parameter of a motor in a circuit breaker performing each control action is acquired, and a preset fault tolerance time length is acquired. Then, the motor is controlled to perform a corresponding target control action according to the action time parameter and the preset fault tolerance time length, so as to drive an operating mechanism of the circuit breaker to act. Next, the action position of the operating mechanism is detected, and when the action position reaches a preset target position corresponding to the target control action or the detection time length reaches a target time length, it is determined that the target control action is completed. In this way, by controlling the motor to act first and then detecting the position, and by setting the target time length as the maximum time length of the motor action, the start-stop control of the motor is not completely dependent on the feedback result of the position detection device, and the situation that the circuit breaker works abnormally due to the failure of the position detection device is avoided.
