摘　　要：为了提高快速斥力机构的分闸速度,采用有限元法,根据灭磁开关对快速斥力机构的动态特性要求,利用Maxwell电磁仿真软件对快速斥力机构建立二维轴对称模型,仿真分析斥力盘厚度、半径、材料、间距、线圈匝数、电容容量和电压对快速斥力机构动态特性的影响。结果表明,优化相关参数可提高快速斥力机构动态特性,能为快速斥力机构样机设计提供指导。In order to improve the breaking speed of the rapid repulsion mechanism and meet the requirements of demagnetization switch applications,the finite element method is used to establish a two-dimensional axisymmetric model of the rapid repulsion mechanism with Maxwell electromagnetic simulation software according to the dynamic characteristics requirements of the demagnetization switch for the rapid repulsion mechanism.The effects of the thickness,radius,material,spacing,coil turns,capacitance,and voltage of the repulsive disk on the dynamic characteristics of the rapid repulsion mechanism are analyzed through simulation.The results show that the optimizing relevant parameters can improve the dynamic characteristics of the fast repulsion mechanism,and the simulation results provide guidance for the prototype design of the fast repulsion mechanism.
