摘　　要：对2011年冰灾中贵州电网在110 kV及以下输电线路采取的融冰方法进行了总结,分析了各种方法的应用范围,比较其优缺点。基于贵州电网的实践,提出主要采用车载直流融冰装置和融冰变压器两种措施进行110 kV及以下输电线路融冰,并完成了相应样机的研制。现场试验证明了所提措施的可行性。Summarizing the de-icing methods for the transmission lines at the 110 kV vogtage and below levels in Guizhou Power Grid in 2011,this paper analyzes the application scope of each method,and compares their advantages and disadvantages.Based on the practice in Guizhou Power Grid,it is proposed that two methods,i.e.,vehicle-based DC-Dicer and deicing transformer,can be mainly adopted for the 110 kV and below transmission line de-icing,and the corresponding prototypes have been developed.The field tests of these prototypes demonstrate the feasibility of proposed mehtod.
