摘　　要：采用模型试验方法修正特高压直流输电线路雷电屏蔽性能的计算方法,并对其影响因素进行了分析.针对当前国内外已开展的模型试验、现场观测与计算方法中存在的问题和不足,结合昆明特高压国家工程实验室的试验条件和国内外已有试验与观测结果,设计了±800kV特高压直流输电线路典型间隙试验、击距模型试验和上行先导模型试验的关键参数、结构布置与试验方案.Scale model experiment was used to revise the calculation method and the influence factors about lightning shielding performance of UHVDC transmission line were analyzed. According to the problems a- bout scale model experiment, on-site observation and calculation method from domestic and oversea re- searchers, combining the test conditions of Kunming national engineering laboratory for UHV engineering technology, the existing experimental and observation results, this paper designed the key parameters, layout and experimental projects of typical air gap experiment, strike distance scale model experiment and upward leader scale model experiment of the ±800 kV UHVDC transmission line.
