摘　　要：高压直流穿墙套管是换流变电站输电设备的重要设备之一,针对高压直流套管的研究工作对中国发展高压直流输电技术具有重大意义。文中以额定电压±400 kV,额定电流4 000 A交流直流互换型穿墙套管为设计对象,研究了高压直流穿墙套管绝缘结构分析与优化中遇到的关键性问题,重点对高压直流穿墙套管的机械性强度与强电场环境空间电荷影响下的高压直流设备的电场计算方法以及绝缘材料的选用进行试验研究与计算,并得出重要结论,具有重要的应用价值。High DC voltage bushing is one of the important equipment for the transmission flow of power station equipment. The research of high voltage direct current casing is of great significance to the development of high voltage direct current transmission technology in China. For the design of the rated voltage of ±400 k V, rated current DC 4 000 A swap type bushing, HVDC wall bushings key issues insulation structure analysis and optimization have been studied. This article focuses on the field of HVDC equipment under HVDC wall bushings mechanical strength and strong electric charges affect the environment space is calculated and the selection of insulation materials and calculation of experimental research, and draw important conclusions, which have important application.
