【摘要】采用有限元软件ANSYS计算了±800 kV特高压直流复合绝缘子安装均压环前后沿面电场和电位分布;并运用ANSYS随机搜索法的优化技术分析了均压环管半径r、环半径D和抬高距H与复合绝缘子沿面电场分布的规律,通过优化技术分析提出了±800kV特高压直流复合绝缘子优化的均压环结构参数。%Finite element software ANSYS is used to calculate the surface electric potential and electric field distribution of the ± 800 kV UHV DC rod suspension composite insulator before and after the installation of grading rings.Besides,ANSYS random search method is applied to analyze the relationship between grading ring radius r,ring radius D,elevation distance H and the distribution of surface electric field.Through the optimization analysis,the optimized grading ring parameters are proposed for the ± 800 kV UHV DC rod suspension composite insulator. 【总页数】4页(1116-1119)
