摘　　要：为满足在新型杆塔及特殊杆塔上开展带电作业的需求,且提高带电作业的安全性和简便性,引入地电位法带电更换直线双串绝缘子卡具。本项研发主要是利用所研发的卡具实现托起分裂导线两联板的功能,以达到方便快捷开展带电作业的效果。整套工具体积小、重量轻、操作简单,且作业过程不受杆塔空气空隙过小的影响,适用于220 kV输电线路。The clamp for live replacing straight double string insulator by ground potential method is introduced for meeting the needs of live working on new type tower and special tower, as well as improving the operation safety and convenience. This research is mainly to use the developed clamp to hold two joint board of bundled conductor, in order to carry out live working conveniently. The set of tools has the advantages of small volume, light weight, easy operation, the operation process dose not affected by small tower air gap, and applicable for 220 kV transmission line.
