| 摘 要： | 对于直流绝缘子表面电位分布的解释，传统的解释为由于盐密的影响和电导的作用。通过大量的实验总结，认为起主要作用的是水的极化作用，其中不只是盐密电导的作用。从而提出关于湿闪问题新观点。比较好的解释了潮湿天气及盐密较低情况时直流绝缘子串在额定电压下就发生闪络的特殊现象。

| Abstract: | Based on a lot of experiments, the polarizable effect of water is considered as the main reason for the voltage distribution of insulator of HVDC transmission lines, and not only the salt density. The conclusion is helpful to the interpretation of wet flashover and is propitious to interpret the special phenomenon that the flashover of HVDC insulator strings would happen under rating voltage when it rains. |
