摘要

介绍了架空高压和特高压输电线路缺陷的定位方法,并对其进行了评价。其中包括一项利用电晕局部放电检测来发现故障条件的技术,同时从直升机上进行常规目视检查。事实证明,电晕检测系统在定位断链、松动间隔、内部或外部放电的绝缘子以及其他故障线路条件方面非常有用。

Locating defects in high voltage transmission lines
Methods of locating defects in overhead high voltage and extra-high voltage transmission lines are described and evaluated. Included is a technology which utilizes corona partial discharge detection to find faulty conditions while simultaneously performing routine visual inspections from a helicopter. The corona inspection system proved to be very useful in locating broken strands, loose spacers, insulators with internal or external discharges, and other faulty line conditions.
