摘　　要：覆冰是威胁电网安全运行的关键性因素。为了提高电网抵御严重冰雪灾害的能力,保证自然灾害条件下电网的安全稳定运行和对用户的持续供电,根据陕西的地理气候特征,及对近年来覆冰线路事故类型和覆冰绝缘子串闪络特性的分析,在试验研究的基础上提出了输电线路绝缘子串防冰闪措施,实施后能有效预防绝缘子串冰闪事故的发生。Icing is key factor to threaten the safe operation of network. For improving the ability to resist serious icing and snowing, ensuring stable and safe operation and continuous power supply under natural disaster, in accordance with Shaanxi geographical ＆ climatic character, based on the analysis of fault type of iced transmission line and flashover character of iced insulator string in recent years, tbe icing flashover prevention measures of insulator string are put forward based on test and research. The application proved that the measures can effectively prevent the occurrence of insulator string icing flashover.
