摘要(Abstract):
对220 kV典型杆塔结构窗口间隙进行分析,并对输电线路进入等电位的绝缘梯法、绝缘斗臂车法、吊篮法等方法进行了对比,以实际运行经验为参考,提出采用垂直吊篮法进入220 kV输电线路电场。对220 kV输电线路不同塔型垂直吊篮法进入电场的路径及方法进行了分析,最后通过现场实际应用,验证了220 kV输电线路部分杆塔通过垂直吊篮法进入电场进行等电位作业的可行性。
The window gap of 220 kV typical tower structure is analyzed. The insulating ladder method, the insulating bucket method, the hanging basket method and other methods for the transmission line entering equalpotential are compared. A vertical hanging basket method for 220 kV transmission lines entering the electric field is proposed based on the practical operation experience. The path and the method for entering the electric field under the vertical hanging basket method of 220 kV transmission line are analyzed. The result of on-site practical application proves that it is feasible for some poles and towers of 220 kV transmission line to enter the equipotential through the vertical hanging basket method.
