Abstract: In order to improve the working characteristics of high-voltage switchgear and realize the intelligent control of switching equipment, a new control system of high-voltage switching motor operating mechanism is studied based on the voltage space vector control technology of permanent magnet synchronous motor. The current and speed double closed-loop control system model of current static decoupling control strategy is built in MATLAB, and the high-precision and high dynamic response follow-up characteristics of the motor operating mechanism are verified by simulation. Through the control of motor current and speed, the real-time monitoring and control of motion parameters in the process of equipment breaking can be realized, which provides a new direction for intelligent control of high-voltage switchgear.
