摘　　要：基于2008年我国大范围冰灾情况,给出华东电网500 kV输电线路的典型故障类型,针对华东电网的实际情况提出了输电线路覆冰灾害防治体系的总体框架,对框架中的结构抗冰、绝缘优化、覆/融冰机理、冰情监测等各个子模块的研究思路进行了讨论,并介绍其中部分内容的初步研究成果。Based on the large area ice disaster happened in China in 2008, the typical faults of 500 kV lines caused by icing are given. The overall framework of the icing disaster prevention and treatment system for transmission lines is proposed, and issues on anticing structure, insulator optimization, icing/melting mechanisms, and icing monitoring are discussed. Some primary research results are given.
