基于高温损伤的架空地线失效分析

Failure Analysis of Overhead Ground Wire Based on High Temperature Damage

鉴于架空地线高温损伤断裂对电网安全运行产生重要影响,本文结合电网光纤复合架空地线(OPGW)和镀锌钢绞线架空地线高温损伤断裂案例,综述了架空地线失效原因分析方法,提出防范措施,为此类型的架空地线失效分析提供参考。

In view of the important influence of high temperature damage and fracture of overhead ground wire on the secure operation of power grid,combining with the high temperature damage and fracture cases of optical fiber composite overhead ground wire(OPGW)and galvanized steel strand overhead ground wire,the analysis methods of overhead ground wire failure are summarized and preventive measures are proposed in this paper,which provides reference for the failure analysis of this type of overhead ground wire.
