Abstract
Sand weather often occurs in areas with an altitude of 3500 m, which affects the insulation character curve of transmission line gaps. Therefore, so as to investigate the impact of sand on the typical gap discharge character curve of rod and rod plane in high-altitude areas, gap discharge tests were conducted using a simulated wind and sand test device at an altitude of 3500 m in Nachitai under DC voltage conditions. The single variable method was used to obtain the impact of different wind speeds, sand grain charges, and sand grain sizes on the discharge character curve. The results show that in a high altitude area of 3500 m, the effect of sand parameters, including wind and sand conditions, wind speed, sand grain charge, and sand grain size, on the DC discharge voltage of typical gaps between rods and planes is within 3.2%.
