500kV输电线路防脱落工作接地线的研制与应用

Development and Application of the Anti-falling Grounding Wire for 500kV Transmission Line

针对高压输电线路停电检修时使用的抛挂式接地线不易挂设、与导线接触不牢靠、易脱落产生电弧导致断股及脱落等,研制出了新型防脱落工作接地线。现场实际应用表明:所研制的防脱落工作接地线具有操作简单、高效和可靠性高等优点,能够满足输电线路停电检修时工作接地线挂设牢靠的要求,可为输电线路停电检修作业安全提供有力保障。

In order to solve deficiencies of the thrown-hanging grounding wire used during the maintenance of high voltage transmission lines,such as not easy to hang,not reliable contact with conductors,and easy to break off and produce arc which can lead to strand breakage and dropping off,this paper develops a new anti-falling grounding wire.Real application shows that this anti-dropping grounding wire has the advantages of simple operation,high efficiency and high reliability,can meet the requirements of reliable installation,and provide a strong guarantee for the safety of transmission lines maintenance at outage.
