摘　　要：为减少高压电气设备因电晕放电引起的绝缘事故,提高电晕放电的检出率及检测速度,将检测时机和检测方位的选取纳入现场检测工作。通过对"光子数和值"的定义、检测前的背景紫外噪点归零化处理和灵敏度调节,使检测结果更加准确并具有对比意义。另外,提出了一个专门针对紫外检测的基本检测流程,有助于紫外检测工作的开展和电晕放电检测方法的研究。In order to cut down the insulation fault of high voltage electric equipment due to corona discharge,enhance the detectable rate and detecting velocity of corona discharge,the selection of detecting opportunity and detecting position have been brought into scene detection.By definition to the summation of UV-photons,zero processing of the Background noise and sensitivity adjustment before detection,the results is more accurate and meaningful.Additional,a basic detection process of UV detection specifically has been put forward,it contribute to the UV detection and research on the detection mothed of corona discharge.
