摘　　要：针对2008年南方电网50年未遇的罕见冰雪灾害情况,介绍了国内外输电线路高频、高压融冰有关理论及当前研究状况。参照110kV输电线路建立融冰仿真计算模型,对不同线路长度、频率、冰介质参数进行仿真计算,对融冰设备的设计、制造进行了初步分析,提出了需要进一步研究的问题和研究思路。In view of the damage of China Southern Power Grid in 2008 caused by the worst ice and snow disaster in 50 years, the paper describes the theories and the state of art about high-frequency and high-voltage deicing of power transmission lines at home and abroad. A deicing simulation calculation model is built according to 110 kV transmission lines, and different line length, frequency and ice dielectric parameter are calculated. The design and manufacture of deicing equipment are analyzed briefly. Issues for further study and the study way are presented.
