750kV带电更换耐张双联串单片绝缘子技术

摘要

To reduce planned and unplanned power cut of 750 kV transmission line,use of the ＂cross two short three＂ method carry out the live work of the tension-resistant single low value or zero value insulator replacement.Aiming at the problems of the ＂cross two short three＂ method,makes technological improvements on the operation tools and the work flow processes,reduces the work hardness of the operators furtherly,improves work efficiency,expands operations space and reduces the risk of work security.The method has significant safe and economic benefits.%为减少750 kV输电线路计划性停电及非计划性停电,采用＂跨二短三＂方法开展耐张单片低值零值绝缘子带电更换技术。针对＂跨二短三＂法存在的问题,通过对其操作工具及作业流程进行技术改进,可进一步降低操作人员的作业难度,提高工作效率,扩大作业适应面,降低作业安全风险。具有显著的安全效益和经济效益。
