摘　　要：由于紧凑型线路塔头尺寸紧凑,相间距离较小,给带电作业带来了较大的限制。1996—1998年,华北电科院等单位对我国首条500kV紧凑型昌房线进行了系统的带电作业研究,实现了1000m海拔高度以下的紧凑型输电线路带电作业。随着紧凑型输电技术的推广,其应用范围逐步扩大至高海拔地区。通过真型模拟塔头冲击放电试验、过电压计算校核及危险率核算,对应用在1000～2100m海拔高度地区的紧凑型线路新塔型CZ25的带电作业方式以及安全性问题开展研究,并实现了2100m海拔高度范围内500kV紧凑型线路的带电作业,为其他紧凑型线路的带电作业奠定了基础。As for the compact transmission lines, the compact size of the tower head, and the smaller phase-to-phase distance bring a variety of limits to live working. From 1996 to 1998, due to the first 500 kV compact transmission line in China called Chang-Fang transmission line, systemic research of live working was held in North China Electric Power Research Institute （NCEPRI）, and finally live working on 500 kV compact transmission line under 1 000 m altitude area was realized. In this paper, through the experiments on mimic real configuration tower of the existing 500 kV compact transmission line, over-voltage calculation, dangerous rate checking and live working methods were determined in 1 000-2 100 m high altitude area.
