摘　　要：介绍了机械固定用±800kV棒形支柱瓷芯复合绝缘子的设计、计算、制造、试验等试制情况。根据产品的使用特点,对高温硫化硅橡胶伞套材料配方进行了改进与完善;采用"ANSYS"三维有限元对金属附件进行了分析论证;对水泥胶合剂和硅橡胶与瓷芯棒用粘接剂进行了一系列的摸索研究;通过对绝缘子的电场分布计算,优化了绝缘子的整体结构设计和均压环配置;同时,进行了特高压输电系统用支柱绝缘子的结构抗震稳定性计算。试验结果表明,产品通过了所要求的23项定型试验。The design, calculation, manufacture and test of composite post insulator with porcelain core for ±800 kV D.C. system was described. The RTV shed material formula was improved according to its service designation, the metal fittings were evaluated using three-demensional finite elements program ＂ANSYS＂ and experimental works were conducted on cementing material and adhesive between silicone rubber and FRP core. Electrical stress along insulator was calculated for optimizing integrated insulator design and grading ring arrangement. Moreover, the seismic stability of post insulator design was evaluated for UHV transmission system. The calculation results show satisfaction to all 23 type test items.
