摘　　要：根据在人工气候室中的一系列试验结果,得出了气压、淋雨、污秽和覆冰与线路绝缘子直流放电电压的相关关系。从而探讨了恶劣环境条件下直流线路绝缘子的选择原则。Based on the test results obtained in the artifitial climate chamber, this paper presents the relations between the DC flashover voltage of line insulators and pressure, rain,pollution as well as ice, and discusses the principle of choosing the DC line insula tors under the severe environment condition.

关 键 词：直流输电 绝缘子 污闪 放电电压
