500kV交、直流输电线路鸟啄损坏复合绝缘子统计和分析

Statistic and Analysis on Bird Damage to 500kV AC and DC Transmission Line Composite Insulators

对河南、湖北、浙江三省500kV交、直流输电线路运行复合绝缘子鸟啄导致损坏的情况进行了调查统计,认为鸟啄绝缘子的主要原因与鸟增多,线路是否带电运行,均压装置的设计是否合理,绝缘子串型,绝缘子颜色和气味等因素有关。建议将复合绝缘子均压装置改造为防鸟粪式均压装置,并在鸟害严重区的线路杆塔上安装驱鸟装置。复合绝缘子制造企业应调整硅橡胶配方,运行部门可采取在投运前将绝缘子包裹的方式来保护复合绝缘子。

Based on the investigation and statistic on bird damage to 500kV AC and DC transmission line composite insulators in Henan,Hubei and Zhejiang province,the main cause of bird pecked insulators is considered on the amount of bird increasing too much,wether or not energised,the design of grading fitting, the insulator string design ,the colour and odour of insulator and so on. Some advices and protect measures consisting of re-designing grading fitting, setting bird dispelling fitting,adjusting silicone rubber ingredient and covering insulators before line commissioning and etc have been presented in this paper.
