摘　　要：输电线路覆冰可引起导线舞动、杆塔倾斜、倒塌、断线及绝缘子闪络等问题。本文针对导线覆冰带来的危害,从预防电网覆冰灾害,建立科学的电网覆冰灾害抢修机制等方面出发,提出了多项防治措施,对覆冰区输电线路设计、运行以及提高整个电力系统的安全可靠性具有重要的实际意义和指导作用。Transmission line regelation may cause conductor galloping, pole leaning or collapse, conductor breaking or insulator flashover etc.As for the harm caused by transmission line regelation, this paper proposed preventive measures from two aspects： prevention of power grid icing and establishing mechanism of grid icing. Therefore, the paper had important theoretic and practical meaning to the design and operation of transmission line icing and enhancement of power grid safety.
