摘　　要：复合绝缘子作为防污闪的主要设施,已在我国架空输电线路中得到了广泛应用,鸟啄复合绝缘子是威胁架空输电线路安全稳定运行的重要因素之一,河南电网在输电线路的检修运行工作中多次出现了复合绝缘子被鸟啄的情况,直接威胁了电网的安全运行。河南电网对全省范围内500 kV线路鸟啄情况进行了统计,尤其对濮阳地区的鸟啄线路附近的鸟粪成分进行了分析。结果发现,鸟粪中有硅橡胶成分,这是鸟啄复合绝缘子吞食、消化后进入鸟类粪便造成的,并分析了鸟啄绝缘子的可能原因,提出了架空输电线路防鸟啄的措施。As an important anti-pollution flashover method, composite insulators have been widely used in overhead transmission lines. Bird damage is one of the most important factors which threatened the safety and stability of the operation of overhead transmission lines. It is found that composite insulators are always pecked by birds in the maintenance of power transmission lines in Henan province, and this phenomenon directly threatened the secure operation of power system. Recently, researchers from Henan Electrical Power Company have carefully investigated the bird damage of 500 kV transmission lines located in Henan province, and analyzed the guano near the transmission lines pecked in Puyang district. It is found that there are silicone rubber compositions in the guano, and it is caused that part of composite insulators is swallowed by the birds near the transmission lines. The possible reasons of bird damage to insulators are analyzed and suggestions to prevent overhead transmission lines from bird damages are proposed.
