Design of Bistable Permanent Magnet Mechanism for 12KV Vacuum Circuit Breaker

摘要

In order to solve the problem of design of bistable permanent magnet mechanism with vacuum interrupter, this paper firstly chooses the dimensions of the permanent magnet mechanism and the selection of material properties according to the mechanical parameters of the vacuum interrupter. Using the electromagnetic analysis software ANSYS Maxwell to analyze the two-dimensional model of the permanent magnet actuator. In the dynamic analysis, the optimization of the separation and closing result can be realized by changing the voltage and capacitance capacity of the coil power supply capacitor. The experiment verifies the correctness of the method.
