浅析都匀电网110kV线路方式融冰与交流短路融冰特点

都匀电网冬季易发凝冻灾害，110kV线路应及时根据覆冰跟踪情况安排融冰以避免发生因覆冰导致线路倒杆的事故。根据都匀电网2011年初凝；东期间实施的110kV线路方式融冰和交流短路融冰的实际情况，分析并总结了都匀电网110kV线路采用的两种融冰方式的特点及今后需要改进的方向，并对未来都匀电网融冰规划提出意见及建议。

Analysis of the characteristics of working ice - melting and AC short circuit ice - melting for 110kV line of Duyun power grid

Since freeze disaster is easy to occur for Duyun power grid in winters, ice - melting should be taken into consideration ac- cording to the situation of timely ice - covering to 110kV line with avoiding the accident of pole collapse. Based on the reality of work- ing ice - melting and AC short circuit ice - melting of 110kV line taken in Duyun power grid during the freezing period of early 2011, the characteristics of the two ice - melting ways and the modified direction in future for the 110kV line of Duyun power grid are ana- lyzed, and the suggestions and proposals of Duyun power grid ice - melting planning are put forword.
