架空输电线路除冰技术分析

如何对覆冰输电线路进行融冰、除冰以降低冰灾损失,目前仍是世界性的技术难题.针对该问题,笔者在现有除冰技术如热力除冰法、机械除冰法以及其它新技术除冰法的基础上,建立了一个简单的输电线路模型,并依次研究各种除冰技术及其实现电路.最后得出适合该输电线路的除冰措施,从而为输电线路在覆冰情况下的除冰提供技术指导.

Analysis of Deicing Methods for Overhead Transmission Lines

At present,how to melt the ice on transmission lines to reduce the losses is still a worldwide technical problem.The existing deicing methods can be divided into three kinds,i.e.the ice-melting method,the mechanical deicing method,and the deicing method with new technology.In this study,a simple transmission line model was established,and the deicing methods mentioned above with their implementation circuits were analyzed respectively.Their advantages and disadvantages were compared.Thus,the most suitable deicing method for the transmission line model was obtained.
