Background
The overhead transmission line is the most important power equipment for realizing the long-distance transmission of electric energy and has the characteristics of high voltage and large current. In the operation process of overhead transmission lines in China, the crimping type electric power fitting bears all tension of a conducting wire or a ground wire, and meanwhile, the conductor plays an overcurrent role, and the fitting is not detached any more once being installed. However, the phenomena of disconnection and the like often occur in the overhead transmission line to cause line accidents, and the operation safety of the transmission line is seriously influenced. Most of the post-processing analysis results are caused by the fact that the operation of crimping the strain clamp and the continuous tube is not in accordance with relevant regulations, and moreover, when the line is in a heavy-load operation condition, the strain clamp and the continuous tube which are not in accordance with the crimping are easy to cause over-high local heating temperature to damage the lead. Therefore, the compression joint quality of the strain clamp seriously influences the safe operation of the power transmission line.
In recent years, an X-ray digital imaging detection technology plays an important role in detecting defects of transmission line hardware fittings, can quickly and accurately detect various structural defects of hardware fittings such as strain clamps, splicing tubes, drainage plates, wires and the like, and is an important technical method for guaranteeing the operation safety of a power transmission network.
