Linear Servo Motor Operating Mechanism and Control Technique for High-Voltage Circuit Breaker

Abstract:

The linear servo motor mechanism for high-voltage circuit breaker is presented and the control to new operating mechanism is analyzed according to the d-q axis mathematics model and the thrust characteristics of the permanent magnetic synchronous motor. The three closed-loop control schemes of location, speed and current for moving contact control is designed and executed on DSP. The high accuracy grating is chosen as the speed and location sensors by which the requirement for real-time and high accuracy in the system can be fulfilled. The control and regulation of the moving contact movement during opening and closing of the high-voltage circuit breaker are realized which make the movement curve the same as the ideal one. The opening and closing abilities and running reliability of circuit breaker are enhanced and the mechanical and electrical lifespan is improved.
