Dynamic Path Planning Method of Motor Drive Mechanism for High-voltage Circuit Breaker
Compared with the traditional operating mechanism,the motor-driven operating mechanism has simple structure and strong action controllability,which greatly improves the controllability and reliability of the opening and closing operation of the circuit breaker.Aiming at the control method of motor-driven mechanism,that is,the motion path method of the mechanism,this paper proposed a dynamic path planning method of the motor-driven mechanism.Based on the established mathematical model between the motor output shaft and the switch moving contact,the mathematical relationship between the optimal motion path of the switch moving contact and the optimal output curve of the switch moving contact was derived.Finally,a 126kV motor-driven operating mechanism test platform was built,which was proved by the results obtained from the test platform.Compared with the preset curve method,the dynamic programming method proposed in this paper can effectively shorten the operation time and improve the mechanical life of the circuit breaker.
