Abstract: 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 about scale model experiment, on-site observation and calculation method from domestic and oversea researchers, 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.

Key words: UHVDC transmission line, lightning shielding, typical air gap, strike distance, upward leader, scale model experiment design, experimental project
