Analysis of Contrast Test between Dry and Wet Flashover Voltage of Composite Insulator

合成绝缘子工频干、 湿 闪络电压对比试验分析

Transmission line icing which is caused by the weather of low temperature ice rain wet snow and frost will bring forth disasters such as icing flashover transmission line galloping line breaking and tower collapse .

低温、冻雨、 湿雪、冰冻等天气会造成输电线路严重覆冰，引起覆冰 闪络、导线舞动、断线、倒塔等电网灾害。

This paper confirms the hydrophobicity transference scheme and describes the influence of hydrophobicity on the wet flashover voltage of silicone rubber composite insulators by comparing the hydrophobicity transference of liquid silicone rubber with that of solid silicone rubber .

论文通过对液体硅橡胶和固体硅橡胶憎水迁移性能的比较，验证了硅橡胶憎水迁移性机理，并通过试验，分析了憎水性对复合绝缘子 湿 闪电压的影响。

The relationship of hydrophobicity and wet flashover voltage of composite insulators is also discussed in this paper .

本文通过试验，分析了复合绝缘子憎水性与其 湿 闪电压的关系。
