摘要:

永磁机构在断路器等开关设备中被广泛应用,是开关设备的关键部件。首先,建立方形永磁机构的三维模型,并基于该模型开展仿真分析,得到方形永磁机构在分合闸状态下的磁场分布和动铁心所受电磁吸力情况。进一步针对方形永磁机构在不同电磁线圈参数和电源电压条件下的分合闸特性进行仿真计算,得出方形永磁机构的动态特性曲线。最后,将仿真结果结合试验样机测试结果进行对比分析,验证了所建方形永磁机构的静态和动态特性仿真的准确性与有效性。

Abstract:

Permanent magnet mechanisms are widely applied in switchgear such as circuit breakers and serve as core executive components of switchgear.A 3D model of the square permanent magnet mechanism is established,and simulation analysis is performed based on this model.The magnetic field distribution and electromagnetic attraction force on the moving iron core of the square permanent magnet mechanism under the opening and closing conditions are acquired.Subsequently,to investigate the dynamic performance, simulation calculations of the opening and closing characteristics of the square permanent magnet mechanism are conducted under different electromagnetic coil parameters and supply voltage.Corresponding dynamic characteristic curves are thus derived.Comparative analysis is conducted with the test results of the experimental prototype,which verifies the correctness of the simulations for the static and dynamic characteristics of the square permanent magnet mechanism.

Key words: square permanent magnet mechanism, static characteristics, dynamic characteristics, simulation study
