架空线路覆冰研究现状综述

An Overview of the Research Situation on the Covering Ice of Overhead Lines

本文首先介绍了我国架空线路覆冰的现状,线路覆冰造成的危害,线路覆冰类型,形成原因、条件和不同类型的覆冰对电网所造成的影响。然后介绍了目前国内外对架空线路覆冰的研究现状,其中研究方法包括在线监测法、称重法、导线倾角法等,并简单介绍了机械除冰法、短路与热力除冰法及它们的适用条件。

We first gave an introduction in this paper to the present situation of covering ice of overhead lines in china, the harms caused by covering ice on the line and types of covering ice of overhead lines in China, reasons and conditions of the formation of covering ice, as well as the influence of different types of covering ice on power grid. Then, we introduced the current research situation of covering ice of overhead lines both at home and abroad, among which the research methods include online inspecting, weighing and dip-angle of wire. What＇s more, some methods of mechanical deicing, short circuit and thermal deicing and the respective conditions of using them were also mentioned in this paper.
