摘　　要：概述了CR与DR两种X射线数字照相系统的组成和工作原理,介绍了电力电缆的故障缺陷类别,并在实验室条件下模拟了三种缺陷,在两种不同的X射线源下进行了CR与DR两种照相技术的检测结果对比。试验结果证明了CR与DR两种X射线数字照相技术均可有效检测电力电缆缺陷,并对比了二者的优缺点,以为电力电缆缺陷检测提供参考依据。This paper summarized the digital imaging system composition and working principle of CR and DR. By using three artificial defects under laboratory conditions, the detected results by CR and DR were compared under two different X-ray sources. The experimental results show that both CR and DR can effectively detect power cable defects and present finding is hoped to provide reference basis for the defect detection of power cable.
