High-Precision Joint Simulation and Intelligent Trajectory Control of Vacuum Switch Permanent Magnet Mechanism

The phase-controlled breaking and closing technology is mainly used to achieve flexible switching by precisely breaking and closing the vacuum switch at the target phase point with adjustable speed, thus suppressing or even eliminating the harmful inrush and overvoltage caused by random phase switching. In this paper, the dynamic characteristics of 10kV vacuum switch permanent magnet mechanism are analyzed, establish an accurate model of the permanent magnet mechanism in ANSYS and an intelligent control model in MALAB, and finally complete the joint simulation, and use the improved fuzzy control algorithm combined with the back propagation neural network algorithm to design the controller for closing control on the basis of the traditional fuzzy control, and monitor the displacement of the mechanism and the coil current curve in BP real time. The current curve of the coil is monitored in real time, and the permanent magnet mechanism is driven to move according to the standard displacement curve to reduce the dispersion of its action, so as to improve the accuracy of phase control. In this paper, by varying the influencing factors such as capacitor voltage, capacitor capacity, external load force and temperature, the results show that the designed intelligent controller can realize the trajectory control of the vacuum switch.
