输电线路覆冰形成机理分析

Analysis on the Formation Mechanism of Ice Coating Transmisson Lines

输电线路覆冰是受微气象、微地形及温度、湿度、冷暖空气对流、环流以及风速风向等因素影响的综合物理现象。按冰的形成机理,覆冰可分为降水覆冰、云中覆冰、凝华覆冰,其中以降水覆冰产生的雨凇冰最危险。

Transmission Lines＇ regelation is a comprehensive physical phonomena influenced micro-climate, micro-topography, temperature, humidity, convection between hot and cold air, as wind speed and direction. Regelation can be classified into precipitation regelation, regelation limation regelation. Among the three, rain rime ice resulting from precipitation regelation is the by factors such as circulation as well in clouds and submost dangerous.
