2013年1月至2014年9月,采用样线法和样点法对河南省域高压输电线路涉鸟故障进行调查,并对2003到2013年间该地区涉鸟故障相关信息进行统计分析.结果显示,该地区发生的涉鸟故障跳闸事故64次.涉鸟故障发生的地理环境特征为豫中西部53次,占82.8%,且与候鸟迁徙通道相重叠.涉鸟故障的季节性规律为冬春季节是鸟害的高发期,与冬候鸟迁徙活动周期相同,发生在10月至次年3月,6个月间共计48次,占涉鸟故障总数的75%.涉鸟故障的日节律表明晚间为高发期,晚19:00至次日7:。O时段发生鸟害跳闸50次,占78.13%;其中6:00至7:00时段发生17次,占26.56%.对涉害鸟类生物学习性进行分析,依据鸟害的原因及特点,将涉鸟故障划分为鸟粪闪络、鸟巢短路、鸟体短接、叨啄复合绝缘子4种类型.建议将目前普遍采取的以“堵”为主的隔离型、驱逐型措施,改进为以引导型为主,隔离型、驱逐型相辅,“堵”、“疏”相结合的综合措施.
Through the statistics, analysis and field investigations of failures due to bird-trouble from 2003 to 2013 in the high voltage transmission lines in Henan province, the results show that the tripping events occur 64 times during the last eleven years, where 82.8% (53 times)of them occur in the middle and western Henan province, overlapping the migration corridor of snowbirds. The seasonal law of the bird trouble is similar to the migration of winter visitor birds, and tends to occur in spring and winter, 48 times (about 75%)bird-trouble occurring between October and late March. Through the statistics and analysis of the daily rhythm, the results show that 50 times (about 78.13%)tripping events occur between 7pro and late 7am, especially between 6am and 7am, 17 times tripping occuring accounting for 26.560%. Through analysis of the biological characteristics of trouble birds and the causes and characteristics of bird-trouble, the four types were divided including guano caused flashover, nest-caused short circuit, body-caused short touch and pecking composite insulators. Based on this study, the author advised that isolating-type, expelling-type, leading-tye methods should be adopted to displace the isolating-type, expelling-typ methods. Blocking and leading should be coordinated to deal with the bird-trouble.
