摘要
近几年,随着生态环境的逐步改善,鸟类数量逐渐增多,在输电线路杆塔活动越来越频繁,鸟粪和鸟巢对220 kV线路安全运行的影响越来越大,鸟害成为引起220 kV线路跳闸的一个重要因素。防止线路鸟害是保证线路安全稳定运行的一项重要措施,鸟害初期主要发生在边相,运行单位对边相进行封堵后,鸟害逐步向中相转移。而在中相绝缘子上方采用防鸟盒、防鸟挡板等措施,可有效减少线路鸟害的发生几率,降低线路鸟害跳闸率,提高线路的可靠运行。
Recent years,bird damage has become a vital fator to cause 220 kV line tripping.Therefore,prevening bird damage is an important measurement to ensure safe and stable operation of the line.Initially,bird damage occurred in side phase.As the result of plugging used in side phase,bird damage happens to middle phase.Bird-preventing box and baffle applied in middle phase can reduce the tripping rate of the line and improve reliability of the line operation.
