摘　　要：针对现有架空输电线路用防鸟挡板存在防护范围不明确、安装工艺要求过高等问题,设计一种磁吸式防鸟挡板。通过分析现有防鸟挡板现场运行存在的问题,搭建110 kV架空输电线路鸟粪闪络仿真模型,分析不同鸟粪滴落位置对复合绝缘子空间电场的影响,以优化闪络路径为主确定了磁吸式防鸟挡板的防护范围,同时对磁吸式防鸟挡板的材质、安装工艺、安装方式等进行了设计和优化。结果表明,新型磁吸式防鸟挡板防护范围满足要求,且安装工艺简便、维护量小,适合大范围推广应用。This study introduces a magnetic bird deterrent shield to address the challenges associated with traditional overhead transmission lines,particularly their ambiguous protective ranges and demanding installation processes.Exis-ting issues associated with current bird deterrent shield field operations are analyzed.Subsequently,a simulation model of bird dropping flashover for a 110 kV overhead transmission line is established.This is utilized to assess the impact of bird droppings on the spatial electric field of composite insulators.Using the flashover path optimization approach,the protective range for the magnetic bird deterrent shield is delineated.Concurrently,design and optimization are carried out concerning the shield′s material,installation procedure,and installation mode.Results indicate that the newly deve-loped magnetic bird deterrent shield′s protective range meets established criteria.It offers a straightforward installation process and demands minimal maintenance,making it highly suitable for extensive deployment.
