摘　　要：高压开关操动电磁铁是连接设备控制系统和机械系统的关键元件,对其进行设计优化十分必要。根据用户实际需求,以现有产品为例,分析电磁铁线圈布线结构,在既定线圈功率和线圈尺寸的前提下,给出线圈安匝数的最优化设计方法;并应用有限元仿真软件Ansys-Maxwell,分别对电磁铁的不同衔铁半径和衔铁端面结构方案进行参数化仿真计算,比对仿真结果得到优化方案。经实验验证新设计方案性能优于原设计方案,实现了线圈功率由370 W降低至220 W,且在整段脱扣工作行程中输出力与负载力更具匹配性。Operating electromagnets in high-voltage switches are the key components connecting control systems and mechanical systems. It is necessary to optimize the design of electromagnet. Through the example of an actual product, the winding method of electromagnet coil is analysed, is proposed a way to optimize the ampere-turns of coil this paper also focus on when the power and shape size are given. And simulating parametrization designs of different armature radiuses and end face structures are carried out with finite element analysis software AnsysMaxwell. The optimized design can be obtained by comparing the simulation results. Experiment shows that the new design is superior to the original design on power and output force. The rated power is reduced from 370W to 220W, and the output force and load force are more matched.
