摘　　要：本文根据在人工气候室中的模拟试验结果得出了在高海拔淋雨状态下支柱绝缘子的直流放电电压与海拔高度、淋雨量、雨水电导率、绝缘子结构和电压极性的关系曲线,并对高海拔直流淋雨放电特性进行了分析。In this paper, the curves which show the relations between DC flashover voltage of support insulators and altitude, precipitation rate,water resistivity,shape of support ittsulators as well as voltage polarity were presented according to simulation test results in artifical climate chamber. DC flashover characteristics under wet condition at high altitude have been andlvsed.
