Live X-ray non-destructive testing method for crimping defects of strain clamps on transmission lines

为提高输电线路耐张线夹压接缺陷检测的工作时效,提出了一种输电线路耐张线夹压接缺陷带电X射线无损检测方法。根据X射线无损检测技术原理对带电输电线路耐张线夹压接缺陷进行检测,获取缺陷检测图像,通过LVQ神经网络对缺陷图像边缘检测,通过划分图像像素点,获得目标边界图像,以此完成输电线路耐张线夹压接缺陷带电X射线无损检测。实验结果表明,此次研究方法不仅降低了缺陷检测误差,还缩短了缺陷检测时间,满足缺陷检测方法的设计需求。

According to the principle of X-ray non-destructive testing technology,the transmission line tension clamp crimping defects are detected,the defect detection image is obtained,the edge of the defect image is detected through the LVQ neural network,and the target boundary image is obtained by dividing the image pixels.The experimental results show that this research method not only reduces the defect detection error,but also shortens the defect detection time.
