Abstract: | For the low detection accuracy of current corona discharge detection methods, a corona discharge detection method based on ultraviolet imaging is proposed. The method divides the interference factors of corona discharge detection effect based on ultraviolet imaging into distance, gain, temperature and humidity detection, etc. The UV imaging corona discharge detection system is constructed, and the objective lens system is used to solve the problem of corona discharge target imaging. The photosensor photoelectrically converts the image of the corona discharge, and combines the ultraviolet filter to filter out the light wave outside the day blind zone. And the control analysis system is used to statistically analyze the intensity of the light and control the entire detection system. The corona discharge image information is fused and displayed by an image display system. On the basis of the ultraviolet imaging corona discharge detection system, the detection interference factors are processed one by one, and the corona discharge detection flow chart based on ultraviolet imaging is designed to complete the high-quality detection of corona discharge. Experiments show that the proposed method not only deals with the corona discharge detection interference factors effectively, but also improves the detection accuracy of the discharge power detection. |
