摘  要:输电线路是电网电能传输的重要通道,输电线路带电作业对提高供电可靠率、减少停电时间作出重要贡献,它已经成为提高电网经济效益和电网设备安全运行的重要检修手段。本文针对输电线路直线塔带电检修时遇到天气突变,恰好遭遇施工设计时留下的缺陷,例如金具尺寸不吻合等特殊情况,导致不能快速恢复直线串导线的支撑连接,不能立即撤下作业工器具和撤离人员,以至于留下设备和人员的安全隐患,提出研制输电线路带电作业直线串导线临时防雨支撑棒专用工具的思路,起到临时支撑导线,保障人员和工具安全撤离,等待风雨过后再完成作业任务的作用。并介绍了导线临时防雨支撑棒工具的实用性,极大地提高了目前带电检修输电线路直线塔工作的安全性,推动带电作业的发展。Transmission line is an important channel for power grid transmission.The live line operation has made an important contribution to improve the reliability of power failure.It has become an important means of maintenance to improve the economic benefits of power grid and the safe operation of power grid equipment.This paper deals with the sudden change of weather when the line tower of transmission line is overhauled,and it happens to encounter the defects left by the construction design at this time.For example,the size of thefittings does not match,such as special circumstances,such as can not quickly restore the straight line of wire support connection,can not immediately remove the equipment and personnel evacuation,so that leave equipment and personnel safety risks.Therefore,the idea of developing a special tool for temporary rainproof support rod of line string conductors in live operation of transmission lines is put forward,provides temporary support for wires,personnel and tools to evacuate safely and wait until after the storm to complete the task.This paper also introduces the practicability of the traverse temporary rain proof support rod tool,which greatly improves the safety of the line tower working in the current live line operation.and promotes the development of live line operation.
