摘　　要：针对微地形区的覆冰问题开展理论探讨,从微地形区特点、覆冰机理、路径选择、线路设计及改造等方面提出了一些措施,如涂刷憎水性和憎冰性涂料、改进绝缘子串型布置、采用复合绝缘子或均压措施等,以防止和减少严重覆冰对电网安全造成的破坏和影响。Focuses on micro-topography area of ice cover theoretical issues, and some measures are proposed from characteristics of the micro-terrain region, ice mechanism, transmission lines selection, line designing and other aspects of reform, such as brushing hydrophobic and anti-ice coating, improving insulator string type arrangement, using composite insulator or equalizing measures, so as to prevent and reduce serious ice damage to the power grid and impact of system security.
