Dynamic Characteristics Simulation of the Repulsion Mechanism and the Magnetic Mechanism

Abstract

As the new types of operating mechanisms, electromagnetic repulsion mechanism and magnetic mechanism have the advantages of simple structure, easy control and high reliability. Firstly, the principle of repulsion mechanism and magnetic mechanism is introduced in this paper. Then, the simulation models of 1100kV bypass switch repulsion mechanism and magnetic mechanism are established. The dynamic characteristics of the mechanism are simulated and analyzed, and the corresponding optimal parameters are obtained. Finally, the action speed, the output force and the control circuit current of the repulsion mechanism and magnetic mechanism are compared. The simulation results show that the initial output of the repulsion mechanism is too large and the later output is insufficient, while the driving current of the magnetic mechanism is moderate and the output is uniform, so the magnetic mechanism is more suitable for long stroke bypass switch.
