“…But other defects, such as the steel anchor with burrs and under pressure of the steel anchor slot at the pressure of the aluminum tube cannot be detected. With the increasing use of X-ray nondestructive testing to find electrical equipment [3] , X-ray nondestructive testing provides an intuitive, convenient means of detection compared to traditional methods. With X-ray nondestructive testing technology in applying the quality of crimping of strain clamps, many X-ray pictures of strain clamps need to be identified manually to detect defects [4] .…”

Strain clamps in the transmission line have a vital role. With X-ray inspection in the transmission line, X-ray images to check defects of the tensioning line clip method have already become the mainstream method. In this paper, we concentrate on the strain clamps’ steel anchor end and strand distance defects. We propose a method based on the rotated object detection model RoI Transformer with KFIoU loss to extract the diameter of the steel anchor tube as a reference to determine whether the distance is too long. We first obtain the rotated bounding boxes of the steel anchor and the strand, then calculate the distance between the steel anchor end and the strand and the diameter of the steel anchor by rotated bounding boxes, and finally determine whether there is a defect. Through the study of this essay, the defect detection of strain clamps realizes with high accuracy which has an essential reference for the quality inspection of tension clamp crimping in engineering applications.

“…The traditional methods of strain clamps' detection are complicated and inefficient, such as appearance detection, size testing, mechanical properties of random detection [1] . Now the detection technique based on X-ray images is gradually promoted for electrical equipment [2] , strain clamps not excluded. And with the advancement of image processing technology, the detection of defects has become more and more convenient.…”

Strain clamps of transmission lines are the main part of transmission lines, which play the role of bearing tensile force and transmitting current in the transmission line. In this paper, we focus on the distance between the end of steel anchor and strand in the strain clamps. We propose a method using YOLOv4 and classic image processing methods to measure the distance referred to above, according to which we can judge whether the strain clamps have defects about distance. We first got the bounding boxes of the end of steel anchor and strand in the strain clamps by YOLOv4, thus calculating the distance between the two bounding boxes. Meanwhile, we used classic image processing methods to get the diameter of the steel anchor. Finally, we calculated the ratio of the two distances mentioned above to determine whether the defect exists. We achieve good performance in the detection of distance defects in strain clamps with high accuracy through the research in this paper.
