摘要

针对110 kV同塔四

回输电线路相间净空距离与横担间距离较近，带电更换悬垂绝缘子串存在一定的难度以及危险性的问题，文中基于有限元仿真从带电作业危险率以及作业人员体表场强两个方面，对比分析了采用等电位作业、地电位作业以及中间电位作业3种不同作业方式时带电作业的安全性。研究表明：等电位、地电位作业方式均存在危险率大于1×10

-5

的情况，不符合安规；而采用中间电位作业法进入电场时的组合间隙以及带电作业危险率均符合安规；且采用中间电位作业法时作业人员体表场强也远小于另外两种作业方式，故使用中间电位作业法更换悬垂绝缘子串满足安全性。

Abstract

In view of the problem that the clearance distance between phases and the distance between cross arms of the 110 kV four-circuit transmission line on the same tower are relatively close

and the live replacement of the suspension insulator string poses certain difficulties and risks

in this paperthe safety in live operation is compared and analyzed by adopting such three different operation modes as equipotential operation

ground potential operation and intermediate potential operationbased on finite element simulation and also from such two aspects as the risk rate of live operation and the strength of the operator’s body surface field. The study shows that the risk rate of equipotential and ground potential operation modes is greater than the case of 1×10

-5

which is not in compliance with safety regulations. However

the combined gap and the risk rate of live working when entering the electric field by using the intermediate potential operation method are more compliance with the safety regulations. In addition

in case of adopting the intermediate potential operation method

the body surface field strength of the operator is also far less than the other two operation modes

therfore using the intermediate potential operation method to replace the suspension insulator string can meet the safety requirements.
