摘　　要： 基于在线监测系统的覆冰监测数据,对南方电网输电线路4种覆冰形态进行研究,分析这些覆冰形态和覆冰量与气温、湿度等气象条件间的关系及其对输电线路的影响。分析结果表明,在一定的风速、云中冰晶含量等条件下,温度只要达到约-5℃就有可能产生雾凇覆冰;云南、贵州高海拔山区由于低温雨雪天气较长,覆冰过程容易向混合淞覆冰发展,对输电线路危害极大。 Based on online monitoring system, four typical icing morphology of transmission lines of South China Power Grid are studied, to analyze the relationship between these icing morphology and air temperature, humidity and other weather conditions and analyze their impact on the transmission line. The results showed that in certain conditions of wind speed and the icing content of cloud, it is possible to produce rime icing as long as about–5 ℃ temperature. Due to the long cold rain and snow weather, in high altitude mountainous area of yunnan and guizhou, icing process easily develop into hybrid battle of ice, great harm to the transmission line.
