摘　　要：线路覆冰是影响超高压输电线路正常运行的一个关键问题,也是致使电力系统出现故障的原因之一,为此,就需要通过有效的手段与方式,做好超高压输电线路的融冰工作.当前直流融冰是一种应用效果较好的融冰技术.文章主要分析直流融冰技术的相关特点以及在超高压输电线路中的相关应用,以供参考.Ultra high voltage transmission can transmit 500~1000 kV,and the electric energy that can be transmitted per kilometer of transmission line is far higher than that of general transmission lines and high-voltage transmission lines.Therefore,the cost return rate of constructing ultra-high voltage transmission lines is higher relatively.In the subsequent use process after the completion of the ultra-high voltage transmission line,line icing is a key problem that affects its normal operation,and it is also one of the reasons for the failure of the power system.Therefore,it is necessary to do a good job of ice melting of the ultra-high voltage transmission line through effective means and methods.DC ice melting is a kind of ice melting technology with good application effect.Based on this,this paper mainly analyzes the relevant characteristics of DC ice melting technology and its application in ultra-high voltage transmission lines for reference.
