配电网直流融冰装置的研制应用

Development and Application of DC Ice-Melting Equipment for Power Distribution Network

摘要: 线路覆冰会引起倒杆断线、跳闸停电等严重后果，采用融冰装置消除覆冰灾害，对电网的安全运行有重要作用，但只有输电网和配电网融冰相互配合，才能发挥融冰装置的最大作用和效益。本文论述了配电网融冰装置区别于输电网的特点，介绍了研制成功的配电网四种模式融冰装置的应用范围、技术方案、技术特点和技术性能，分析了研制的关键技术和解决措施。现场试验和使用取得了满意的融冰效果。

Abstract: The ice-coating of transmission line can cause serious problems such as collapsed pole, broken line, trip power cut and so on. It plays a vital role in safe operation of the electrical network by using ice-melting equipment to eliminate the disaster of ice-coating. But only ice-melting of the power transmission network and the distribution network are coordinated mutually, the function and the benefit of ice-melting equipment can be displayed well. The characteristics of ice-melting equipment for power distribution network are elaborated in this paper, which are distinguished between the power transmission networks. Four kinds of ice-melting equipment for distribution network developed successfully are introduced, including application scope, technical plan, characteristic and performance. The technologies and solution measures are also analyzed. The field test and use have obtained satisfied ice-melting effect.
