摘　　要：利用Ansys软件建立有限元模型,对24 k V真空断路器极柱三维模型通过定性分析,选取恰当的二维特征截面,并相应调整边界条件来进行静电场数值仿真计算,为了使极柱的可靠性更高,对电场分布进行了数值计算和优化,为极柱的结构设计提供理论参考。The software Ansys was used to establish the finite element analysis model.The three-dimensional model of 24 kV vacuum circuit breaker pole column was qualitatively analyzed with the selection of suitable two-dimension characteristic section and the corresponding boundary condition was adjusted to calculate the static electric field simulating calculation.In order to improve the reliability of pole column,the numerical calculation of electric field distribution optimization was carried out to provide the theory reference for the structural design of pole columns.
