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、绝缘子运行情况、接地电阻和西江大跨越等工作进行了分析,明确了运行维护的重点,提出了相应的措施,并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提出了研究方向。This article introduced the operational maintenance of 500 kV Yanxi A＆B transmission line in Foshan power grid andanalyzed the fault, the Operation Charactcristics of insulators, ground resistancc, and Xijiang large crossing overhead transmission line. The focus of the operation maintenance and the measure was talked about. Finally, the research direction of two problems was defined, that one is the big section wire creep deformation to effect the sag, the other is the health State assessment of the large crossing tower.
