In the wind environment with and without dust, the flashover voltage of flat plate model, Uf, increases with the increment of the wind. This increase trend becomes slow when the wind increase to be 4.5m/s. Also, the influence of the charge of sand dust on Uf is small. In the condition of sand dust deposited on flat plate model, there is a minimum value of Uf with the increase of the density of the deposited sand dust. Besides, the flashover voltage of the dust is influenced by the moisture of the dust.

得到了风沙速度、风沙带电量、沙粒沉积量及沙粒含水量等因素对沿面放电的影响规律；在有风有沙和有风无沙时，平板模型沿面闪络电压Uf随风速的增大而增大，当风速达到4.5 m/s后增大趋势变缓；Uf受沙尘的电荷量影响较小；当干沙粒沉积在绝缘表面时，随着沉积密度的增加，Uf存在着极小值；同时，平板模型的闪络电压还与沉积沙粒的含水量有关。
