摘要
文章以湖北电网7～8月份发生的220kV输电线路风偏故障为研究对象,介绍了输电线路风偏跳闸的原理和风偏校核的方法,通过导线对塔身、跳线对塔身风偏放电的实例计算,总结出导线对塔身和跳线对塔身风偏放电的特点和规律,提出了防范风偏跳闸的方法。
This paper studies the windage yaw faults of 220 kV transmission lines occurring from July to August in Hubei power grid. The principles and checking method of windage yaw are described, the characteristics of windage yaw which includes from lines to tower body and jumpers to tower body is summarized, and the prevention methods of windage yaw are proposed.
