Abstract :
The linear servo motor actuator of high-voltage circuit breaker is presented and the control of new actuator is analyzed according to the d-q axis mathematics modal and the thrust characteristics of the permanent magnetic synchronous motor. The three closed-loop control scheme of location, speed and current of the moving contact are designed based on DSP. Finally, the control and regulation on the moving contact movement during the opening and closing of the high-voltage circuit breaker are realized which make the movement curve being better. The opening and closing abilities and running reliability of circuit breaker are enhanced.
