摘要
电缆终端塔上支柱绝缘子将电缆引下线与塔身保持安全距离,运行时长期承受扭曲弯矩、自身重力及自然条件的影响,断裂故障偶有发生。基于某起220kV输电线路电缆终端塔支柱绝缘子断裂故障,进行深入分析,探讨导致绝缘子根部断裂的深层次原因,并据此制定应对举措,避免类似事故发生,以提升输电线路安全运行水平。
The post insulator on the cable terminal tower can maintain the safe distance between the cable lead and tower. But the post insulator may break accidentally due to the long-term inflence of twisting moment, self gravity and natural element. Based on the case study of a post insulator break fault of a 220 kV transmission line, this paper conducts in depth analysis on the leading reasons of the breaking fault and formulates corre- sponding measures to increase the safe operation of transmission line.
