220 kV输电线路风偏故障及防风偏改造

摘要

Transmission line faults caused by windage yaw in the last few years in Changzhi area were analysed technically. Combining with the actual operation experience, three corresponding windage-proof renovation programs were summarized in view of different types of 220 kV transmission line tower. Through practically running,the renovation is verified to be effective so that windage-led trip-out accidents could be avoided.%通过对近几年来国网山西省电力公司长治供电公司的输电线路因突发大风天气引起的风偏故障进行技术分析，结合现场实际运行经验，针对不同类型的220 kV输电线路铁塔总结出3种相应的防风偏改造方案，经过试验和运行，证明防风偏改造是成功有效的，避免了线路风偏跳闸事故。
