摘　　要：带电作业是保证±800 kV特高压直流输电线路安全稳定运行的重要技术手段,相应的研究和应用已陆续开展,积累了较为丰富的理论和实践经验。针对±800 kV特高压直流线路带电作业研究现状,主要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,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有益借鉴和参考。Live working is the important technical method to ensure the safety and stability of ± 800 kV ultra high voltage direct current（UHVDC） transmission line operation, which has been researched and applied in recent years. Large amount of theory and practice experiences have been accumulated relatively. Aimed at the present situation analysis of live-working of ±800 kV UHVDC transmission line, some work was carried out. Firstly, the way of in and out of equipotential zone was analyzed. Next, the working safety distance and complex gap were studied. Then the safety protective principle of operating personnel was determined. Finally, a detection method for insulators based on optical electric field intensity senor was proposed. The work can provide useful reference for live working on ±800 kV UHVDC transmission line.
