摘　　要：鸟粪及异物对一体化防雷绝缘子闪络电压影响较大。以实际运行中的配电线路35 kV一体化防雷绝缘子为例,采用有限元仿真计算软件,分别研究了一体化防雷绝缘子在清洁干燥状态下、鸟粪附着伞裙以及长串鸟粪下落共3种情况下的绝缘子电场分布特性。通过仿真计算阐明了鸟粪出现位置、鸟粪干湿程度、鸟粪形成干燥带等因素对一体化防雷绝缘子沿面电场的影响规律。最后,根据仿真计算结果对35 kV一体化防雷绝缘子提出相应的防鸟害措施。Bird manure and foreign matter have a great influence on the insulator flashover voltage.Taking 35 kV integrated lightning protection insulator of distribution line under actual operation as an example,the electric field distribution characteristics of integrated lightning protection insulator are studied by using finite element simulation software under three conditions,i.e.clean and dry condition,bird manure attached to umbrella skirt and long string of bird manure dropped.Through the simulation calculation,the influences of the location of bird manure,the dry and wet degree of bird manure and the drying belt of bird manure on the electric field along the surface of the integrated lightning protection insulator are clarified.According to the results of simulation calculation,corresponding anti-bird danger measures are proposed for 35 kV integrated lightning protection insulators.
