摘　　要：带电作业可有效保证±800 kV特高压直流输电线路安全稳定运行。针对±800 kV特高压直流线路带电作业研究现状,分析了进出等电位方法,研究了作业安全距离和组合间隙距离,确定了安全防护原则,并提出了一种基于光纤电场传感器的绝缘子检测方法,为±800 kV特高压直流输电线路带电作业提供了依据和参考。Live working can effectively ensure safety and stable operation of ±800 kV ultra high voltage direct current （UHVDC） transmission line. Aiming at the live working of present study situation of ±800 kV UHVDC line, this paper analyzed the way that incoming line and outgoing line are equipotential and studied the operation safety distance and complex gap. The safety protection principle was determined and the insulator test method based on optical electric field intensity sensor was raised, which provide gist and reference for the live working of ±800 kV UHVDC transmission line.
