1000kV特高压交流输电线路复合绝缘子鸟害原因分析及对策

Analysis on Bird Pest of Composite Insulators for 1 000 kV AC Transmission Line and Its Countermeasures

复合绝缘子在特高压交流试验示范工程中广泛使用。对特高压交流试验示范工程线路例行检察中发现500余支复合绝缘子被鸟啄食,复合绝缘子的伞群和芯棒护套遭到破坏,给特高压输电线路安全运行带来隐患。通过对复合绝缘子鸟害情况分析研究发现,鸟害主要与鸟的数量、线路是否带电、复合绝缘子材质等有关。为了保障特高压输电线路的安全可靠运行,提出了防止复合绝缘子鸟害的措施。

Composite insulators are widely used in 1000 kV AC power transmission demonstration project, however during the routine patrol it is found that the skirts and core rod sheaths of more than 500 eomposite insulators are damaged due to the peck, and it will bring hidden troubles to secure operation of 1 000 kV transmission line. By means of analysis and research on the bird pest of composite insulators, the main reasons of bird pest are the increase of birds, transmission line being energized or de-energized and the material used for composite insulators and so on. To ensure secure and reliable operation of 1 000 kV transmission line, some countermeasures to prevent bird pest of composite insulators are given.
