Dynamic characteristic study on permanent magnet actuator for vacuum circuit breaker

提出了一种结构新颖的永磁操动机构。采用ANSOFT9.0软件计算了不同条件下永磁操动机构的三维磁场分布,为了确定永磁操动机构每部分的尺寸,在开断和关合的动态过程中对每个参数的变化进行了仿真。根据仿真结果,制作并装配了样机。所提出的永磁操动机构的可行性及开断和关合动态特性的仿真准确性已通过样机实验数据的证明。

A novel Permanent Magnet Actuator（PMA） is put forward. 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 have 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 have been proved by the tested data of the prototype.
