摘　　要：为满足特高压紧凑型输电线路的设计需要,同时为线路建成后带电检修工作的安全开展提供参数依据,针对紧凑型输电线路带电作业典型工况进行了1:1模拟塔窗试验,获得了带电作业安全距离的放电特性。根据交流线路带电作业安全距离的计算方法,保证作业危险率<10-5,得到了海拔1000 m及以下地区特高压紧凑型输电线路直线塔带电作业最小安全距离,即等电位人员对上方构架为8.4 m、等电位人员对塔身侧方构架为6.9 m、相间为11.6 m;耐张塔最小安全距离为6.3 m。In order to meet the design requirements of ultra high voltage （UHV） compact transmission line, and to provide parameters for live repair working after the transmission line completed, we tested typical working positions in compact transmission line at 1：1 ratio scale simulated tower, and determined the discharge characteristics of live working safety distance. According to the calculation method of live working safety distance in AC transmission line, to ensure live work risk to be less than 10 s, the live working minimum safety distance of 1000 kV compact transmission line at the altitude of 1000 m and the following areas was calculated. The minimum safety distance of potential operator-top cross arm was 8.4 m, potential operator-side frame was 6.9 m, top wire-operator at lower wire was 11.6 m, operator at tension string was 6.3 m.
