Abstract

The authors evaluate the electrical flashover strength of various insulator strings on 500-1200 kV lines, when replacing defective insulators by the live-line maintenance method, to ensure that the lineman will not be subjected to a flashover. Electrical testing of various insulator strings with defective insulators in different positions were carried out at an outdoor high-voltage facility. This paper presents the results of these studies.<>

俄罗斯500-1200千伏线路带电维护经验
本文对500- 1200kv线路上用带电维修方法更换缺陷绝缘子时,各种绝缘子串的电气闪络强度进行了评估,以确保线路人员不会受到闪络的影响。在室外高压设备上,对不同位置有缺陷绝缘子的各种绝缘子串进行了电气试验。本文介绍了这些研究的结果。
