The invention discloses a cable defect detection method and device, a storage medium and a processor. Among them, the method includes: collecting the image of the intermediate joint of the cable to be tested; processing the image of the intermediate joint of the cable to be tested to obtain the defect feature; according to the defect feature, determining the defect detection result of the intermediate joint of the cable to be tested, wherein the defect detection result includes at least one of the following 1: No defects, stains on the surface of the main insulation, scratches on the main insulation, uneven peeling of the outer semi-conductive layer. The invention solves the technical problem in the related art that the fault detection of the intermediate joint cannot be carried out, which leads to the fault of the cable.
Description
technical field [0001] The invention relates to the field of cable detection, in particular to a cable defect detection method and device, a storage medium, and a processor. Background technique [0002] Power cables play a huge role in the construction of smart grids. With the acceleration of urbanization, more and more 10kV power cables are used in power transmission and distribution lines. The intermediate joint is an essential part of the power cable line, and it is also the link most prone to failure. According to statistics, about 30% of cable faults occur in the middle joint part, and the construction defect of the middle joint is the most important reason for the failure of the middle joint of the cable. At present, the research on typical construction defects of power cable intermediate joints is only in terms of their hazards. There is no effective method to detect typical construction defects, and it is impossible to control construction defects from the source. ...
