摘　　要：高海拔、污秽、覆冰单一或综合地区的绝缘子电气性能将显著降低,对于上述地区架设的高压输电线路绝缘子的选择尤为重要。笔者总结了国内外输电线路绝缘子研究的理论和试验成果,从现场观测、试验研究、理论模型等方面分析,提出了高海拔、污秽、覆冰气候地区绝缘子选择的依据和方法,并提出了高海拔、污秽、覆冰综合作用下增加绝缘子运行可靠性的建议,能对已运或将投的超特高压输电线路的绝缘配合选择提供借鉴。The electrical performance of insulators at high-altitude,polluted and icing areas will be significantly reduced,and the selection of HV transmission line insulators in the above extreme climate areas is particularly important. The author summarizes the theoretical and experimental research results of transmission line insulator,from the aspects such as field observation and test research,theoretical model analysis,and the basis and method of insulator selection in high altitude,polluted and icing climate areas are put forward. In addition,some suggestions are put forward to increase the operation reliability of insulators under the combined effects of high altitude,pollution and icing,hoping to provide reference for the insulation coordination selection of UHV transmission lines already in operation or to be put into operation.
