摘　　要：高压电晕放电损耗能量与日盲紫外相机测得的光能之间存在关联,并且日盲紫外相机测得的光能受到一些辐射参数(距离、大气条件和电测试条件等)的影响。此外,日盲紫外相机的光谱带宽也会对光能的测量造成影响。为克服相机输出的局限性,并准确测量相机的的光谱传递函数,首先对采用日盲紫外相机进行高压绝缘子进行局部放电检测的原理进行了介绍,随后对光谱传递函数展开了仿真与试验研究,最终得出高压电晕放电能量与日盲紫外相机测得的光能之间的关系,研究结果表明利用紫外成像技术检测设备电晕放电具有一定意义。Research suggests that there is a correlation between the electric energy loss of the high voltage corona discharge and the optical energy measured by solar-blind ultraviolet camera.What’s more,the optical energy is influenced by some radiometric parameters such as distance,atmospheric conditions,and the test configuration.Moreover,the spectral bandwidth of a solar blind ultraviolet camera also affects the measurement of optical energy.In order to overcome the limitations of the camera output and measure the spectral transfer function of the camera more accurately.The principle of corona partial discharge detection of high voltage insulator by solar-blind ultraviolet camera is proposed,and then,carries out simulation and experiment about the spectral transfer function.Finally,the relationship between the energy of high voltage corona discharge and the optical energy observed by solar-blind ultraviolet camera is obtained.The results show that using ultraviolet imaging technology to detect corona discharge of equipment has certain significance.
