摘要

提出了一种新型永磁作动器。采用ANSOFT9.0软件计算了不同条件下PMA的三维磁性分布。为了确定PMA各部件的尺寸,模拟了PMA在断裂和闭合的动态过程中各参数的变化。根据仿真结果,对样机进行了制造和组装。通过样机的试验数据,验证了该方法的可行性和对破合动态特性仿真的准确性。

Design on permanent magnet actuator and simulation of dynamic characteristic for vacuum circuit breaker
A novel Permanent Magnet Actuator (PMA) is put forward in this paper. The 3D magnetic distributions of PMA in different conditions have been computed, adopting ANSOFT9.0 software. In order to determine the size of each part of PMA, the variations of each parameter haw been simulated in dynamic course of breaking and closing. Based on the simulation results, the prototype is manufactured and assembled. The feasibility of the proposed PMA and the simulation veracity of the dynamic characteristic of breaking and closing hare been proved by the tested data of the prototype.
