摘　　要：介绍了佛山供电局500kV砚西甲、乙线送电线路的运行维护情况。对线路故障、绝缘子运行和接地电阻及西江大跨越等进行了分析,明确了运行维护的重点,提出了相应的措施。就大截面导线蠕变对线路弧垂影响、大跨越铁塔健康状态评估等问题初步提出了研究方向。This article introduces operating maintenance of 500kV Yanxi A＆B lines in Foshan power grid. Based on analyses of line fault, insulators, grounding resistance and Xijiang river-crossing etc. defines the focus of the operating maintenance, and proposes corresponding measure. Finally, the research direction is advanced primary on the big section wire creep influence on line arc-sag and hearth state evaluation for long span line iron tower etc.
