摘要
介绍了等电位作业法工作原理,分析了500kV输电线路不同带电作业方法的特点。针对500kV直线塔中相导线和500kV同塔双回耐张塔结构特点,研制了专用的导线滑车架及地线滑车,探讨出滑车架配合自起降装置进出等电位的新方法,安全高效完成500kV输电线路特殊工况下带电检修作业,保障电网安全稳定运行。
Introduced the working principle of equipotential operation,and analyzed the characteristics of different live working methods for 500kV transmission lines.For the 500kV linear tower phase conductor and 500kV double tower,discussing on the new type of live working entry and exit equipotential method using new equipment of self-propelled device discussing on and 500kV transmission line conductor block and ground block,realize safe and efficient entry and exit equipotential under special working conditions of 500kV transmission line.
