摘　　要：超(特)高压输电线路由于导线截面大、分裂数多、档距长,导线的重量和张力大,使得在超(特)高压输电线路上进行带电更换耐张绝缘子或直线绝缘子棒作业难度较大。针对楚穗±800 kV线路耐张双串单片绝缘子或直线复合绝缘子棒的带电更换作业,给出一种简易的力的计算方法,并据此选择适合的工具吨位。该方法简单、实用,适合现场人员使用。The extra （ultra） high voltage transmission line has large conductor section, large bundled number, large distance, and large conductor weight and tension, which make the live-line work of replacing strain insulator or straight line rod insulator in the extra （ultra） high voltage transmission line more difficulty. A simple force calculation method are proposed for the live-line replacement work of double string single plate insulator or straight line composite rod insulator in ＋800 kV Chu-sui transmission line, based on which the proper tonnage of tools is chosen. The proposed method is simple, practical and suitable for the usage of field personnel.
