冰的电气特性影响输电线路覆冰绝缘子闪络电压。
The flashover voltage of iced insulators of transmission lines is affected by the electrical characteristic of ice.
输电线路覆冰可引起导线舞动、杆塔倾斜、倒塌、断线及绝缘子闪络等问题。
Transmission line regelation may cause conductor galloping, pole leaning or collapse, conductor breaking or insulator flashover etc.
国内外学者对覆冰绝缘子闪络特性进行了大量研究，但是对闪络机理的研究不多。
Therefore, a systematic study of flashover performance and mechanism of insulators covered-with ice has both a very important academic meaning and an engineering value.
