[0002] In the construction of power transmission and distribution lines, the crimping quality of insulator fittings is of vital importance. It is like the cornerstone of line safety and is directly related to the stable operation of the entire power transmission and distribution system. However, the existing means of detecting the crimping quality of insulator fittings are not satisfactory. Traditional detection methods are often inefficient and cannot quickly and accurately detect a large number of insulator fittings, making it difficult to meet the requirements of efficient operation of modern power systems. At the same time, its accuracy needs to be improved, and some minor crimping defects may not be discovered in time, burying hidden dangers to line safety. In addition, the existing detection devices are also lacking in comprehensiveness, and it is difficult to conduct a full range of detection of the tensile and torsional properties of the crimping points, and it is impossible to provide comprehensive and reliable data support for the safety assessment of the line. In summary, there is an urgent need for a new type of insulator fitting crimping quality detection device to overcome the shortcomings of the existing technology and ensure the safe and reliable operation of power transmission and distribution lines.
