【摘要】：为了提高紫外成像对放电检测的准确性,探讨量化放电强度的可能性,使用3台不同紫外成像仪对影响紫外成像的因素进行了对比研究。研究表明:不同厂家、型号的紫外成像仪在相同放电条件下所测的图像和光子数有显著差异;相同条件下,紫外光子数随着增益逐渐增大而增加,到达峰值后开始衰减,其规律受仪器型号和检测距离的影响,3台仪器在检测放电时有其对应的最佳增益;拍摄距离对光子数的影响与增益和仪器有关,光子数与检测距离存在复杂非线性关系;紫外成像仪从正面到侧面检测设备放电的结果基本相同。研究结果对完善紫外成像检测电晕规程和工程应用具有重要的参考价值。
[Abstract]:In order to improve the accuracy of ultraviolet imaging to detect discharge and to discuss the possibility of quantifying discharge intensity, three different ultraviolet imagers were used to compare the factors affecting ultraviolet imaging.The results show that there are significant differences in the number of images and photons measured by the ultraviolet imagers under the same discharge conditions, and under the same conditions, the number of ultraviolet photons increases with the increase of gain and begins to attenuate after reaching the peak value.The rule is influenced by the type of instrument and the detection distance. 3 instruments have their corresponding optimum gain in detecting discharge, the influence of shooting distance on photon number is related to the gain and instrument, and there is a complex nonlinear relationship between photon number and detection distance.The results of the ultraviolet imager from front to side detection equipment discharge are basically the same.The results have important reference value for improving the corona detection rules and engineering application of ultraviolet imaging.
