【摘要】：為了提高紫外成像對放電檢測的準確性,探討量化放電強度的可能性,使用3臺不同紫外成像儀對影響紫外成像的因素進行了對比研究。研究表明:不同廠家、型號的紫外成像儀在相同放電條件下所測的圖像和光子數(shù)有顯著差異;相同條件下,紫外光子數(shù)隨著增益逐漸增大而增加,到達峰值后開始衰減,其規(guī)律受儀器型號和檢測距離的影響,3臺儀器在檢測放電時有其對應(yīng)的最佳增益;拍攝距離對光子數(shù)的影響與增益和儀器有關(guān),光子數(shù)與檢測距離存在復(fù)雜非線性關(guān)系;紫外成像儀從正面到側(cè)面檢測設(shè)備放電的結(jié)果基本相同。研究結(jié)果對完善紫外成像檢測電暈規(guī)程和工程應(yīng)用具有重要的參考價值。
[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.
