摘　　要：采用有限元分析软件ANSYS计算220 kV复合绝缘子电场分布及绝缘子安装均压环后对电场分布的影响。并运用ANSYS软件随机搜索的优化技术分析了均压环的结构参数环径,管径和抬高距与复合绝缘子电场分布的规律,通过优化分析给出了220 kV复合绝缘子优化的均压环参数。The paper carries out the calculation of the electric field distribution of 220 kV composite insulators by using finite element analysis software ANSYS, and analyzes the influence of grading ring installed on insulators on the eleetric field distribution. Moreover, the paper analyzes the relationship between the structural parameters of the ring such as radius, elevation distance and the electric field distribution by ANSYS with random search optimization techniques, based on which the optimized grading ring parameters of the 220kv composite insulator is given.
