摘　　要：随着复合绝缘子使用量的剧增,复合绝缘子闪络及损坏的情况也日渐增多。因此,需要对其各方面性能进行深入的分析和研究。基于推导的分区边界元算法公式,用ANSYS软件建立220kV复合绝缘子不安装均压环及安装均压环的模型,利用FORTRAN语言编制的三维电场分析程序进行计算,分析了均压环位置对电场分布改善效果的影响。With the increases of composite insulators used in service, there emerged many problems, such as the composite insulator flashover and damage. It is very important to study fully the performance of the composite insulators. Based on BEM formula and using the FORTRAN language procedure for calculation of the three-dimensional electric field, electric field distribution of 220kV composite insulators without grading ring or with grading rings, are analyzed by using ANSYS models. And the effect of grading rings location on the electric field distribution is analvzed.
