摘要: 750 kV 输电线路的运行过程中需要对绝缘子进行及时有效的检测,紫外检测是一种快速高效的绝缘子放电检测技术,如何将这种方法应用到750 kV绝缘子检测中尤为重要。通过对750 kV瓷绝缘子进行人工污秽试验的紫外检测结果进行研究,提出了紫外光子数相对波动性以及帧光斑面积均值这2个评估绝缘子放电严重程度的特征量,发现2个特征量均可以有效地评估绝缘子放电严重程度。其结论对紫外检测技术在750 kV绝缘子检测中的应用具有重要意义。

关键词: 紫外检测, 紫外光子数, 光斑面积, 放电严重程度

Abstract: Timely and effective testing of insulators is essential to safe operation of 750 kV transmission line. As a fast and efficient method to detect insulator discharge, ultraviolet detection technique is very important in insulator detection. Ultraviolet detection result of the 750 kV Porcelain Insulator by using artificial pollution test is analyzed first. Two characteristic quantity indexes, fluctuation range of photon number and mean value of spot area, are proposed to evaluate discharge severity. Both indexes can effectively evaluate degree of insulator discharge. The testing results are of great significance to application of UV detection technology in 750 kV insulator testing.

Key words: UV detection, UV photon number, spot area, discharge severity
