| 摘 要： | 分析了雨雾天气高压输电导线上悬挂的水滴受电场力形变过程,对水滴引起的电场畸变进行了动态数值计算。计算结果表明：水滴受到重力和电场力的作用被拉长而曲率半径变小,最大场强值变大。解释了雨雾天气输电线路电晕放电变得强烈的原因。

| Abstract: | With the effect of electric field force and gravity, the shape of raindrop suspending on HV transmission line is changing. The shape changing process of raindrops is analyzed. The electric field distortion values caused by raindrop are calculated dynamically. The calculation results show that the maximum of electric field intensity in- creases when raindrops＇radii is becoming smaller because of lengthening. It gives a good explanation of the phe- nomenon that HV transmission lines＇corona discharge becomes very tense in rain and fog. |
