为研究高海拔地区太阳紫外线辐射对高电压输电工程中空气间隙放电的影响,在总结相关理论的基础上指出应着重研究空气对中长波紫外线的吸收系数,从而在粒子平衡方程中引入紫外线对光电离的影响;其次通过整理相关气象资料,得到了高海拔地区太阳紫外线辐射的基本特征：辐照强度在0～110 W/m2之间,紫外线光谱分布在280～400 nm波长范围内;最后利用超高压氙灯和超高压汞氙灯两种光源分别模拟太阳紫外线辐射。比较发现,氙灯模拟效更佳。基于测量数据提出了改进模拟效果的方案：一方面应该将模拟光源的光谱中波长〈280nm部分紫外线过滤;另一方面将多盏氙灯适当组合,实现大面积、高强度、均匀照射。

In order to research the effect of solar ultraviolet irradiation（UV） on the discharge of air gap in high voltage engineering in high altitude areas,by some relevant theories,we pointed out that the absorption coefficient of air on UV of middle-long wavelength should be focused on,and the equation of particles equilibrium should be used to research the effect of UV on photo ionization.Moreover,we obtained the basic characteristics of solar UV in high altitude areas by systemizing meteorological data： the intensity of UV distributes in 0~110 W/m2,and the wavelength of UV spreads between 280 nm and 400 nm.Finally,the solar UV was imitated by using ultra high pressure xenon lamps（Xe） and ultra high pressure hydrargyrum-xenon lamps（Hg-Xe）,respectively.It is found that the imitating result of Xe is better than that of Hg-Xe.Based on the measured data,improvements in the imitation effectiveness are suggested： on the one hand,the UV wavelengths which are shorter than 280 nm should be filtrated from the irradiation of the imitating light sources,on the other hand,the light source＇s radiation of large area,high intensity and uniformity can be achieved via proper combination of several Xe lamps.
