摘要
在江西省经受了50年不遇的冰灾后,根据对江西省网OPGW线路中断情况的统计,认为OPGW及地线的覆冰中断是引起电力输电线路故障的重要原因之一。分析了现有的几种除冰技术在电网内的适用性,阐述了"抗覆冰OPGW"的抗覆冰原理,针对当前常见的中心束管及层绞式等OPGW结构,设计了增加抗覆冰导线的模型,并结合光纤测温技术,设计出了"抗覆冰OPGW"在电网中可实施的具体应用方式。
This paper makes the statistical analysis on the failure of OPGW in Jiangxi power grid after the heavy snows and ice disaster, and points out that the icing coating is one of the major reasons causing the failure of power transmission lines. It analyses several deicing technologies and the applications in power grid, discusses the principles of anti-icing OPGW. The OPGW models added anti-icing conductors are also introduced in the paper.
