Research on AC Discharge Characteristics of Compact Tower Window-Line Air Gap under the Influence of Bird Streamer

查明鸟粪引起的紧凑型塔窗横担-导线空气间隙的放电原理,减少鸟害故障的发生,提高电力系统的安全运行。根据鸟粪电导率、粘度等各种参数,对紧凑型塔窗-导线空气间隙交流放电特性进行了模拟试验研究。结果表明:鸟粪污染引起塔窗-导线间隙的击穿电压降低约80%。为降低鸟害故障率,提出防治鸟害的有效措施。

The discharge principle of compact tower window cross arm - line air gap caused by bird streamer is found to reduce the bird caused fault and improve the security operation of electric power system. Simulation experiments for AC discharge characteristics of compact tower window - line air gap have been studied based on parameters of electric conductive and viscosity of bird streamer. The result shows that the breakdown voltage of the tower window - line air gap polluted by bird streamer decreased about 80%. In order to reduce the ratio of bird caused fault, effective measures to prevent bird damage are proposed.
