Abstract

The invention relates to an infrared visual inspection device oriented to cable aging position detection and belongs to the technical field of electric power and infrared detection. The infrared visual inspection device oriented to cable aging position detection is characterized in that an upper annular ring, a middle annular ring and a lower annular ring do not have rotation functions, and only each of the upper annular ring and the lower annular ring is provided with three infrared cameras; on the projection onto a cable cross-section, the upper first infrared camera, the lower first infrared camera, the upper second infrared camera, the lower second infrared camera, the upper third infrared camera and the lower third infrared camera are arranged successively at equal intervals. Compared with the invention a power line aging infrared detection device and detection method, the infrared visual inspection device oriented to cable aging position detection eliminates the rotation functions of the upper annular ring and the middle annular ring, and the lower annular ring, and the three cameras of the middle annular ring so that the complexity of the device can be reduced and the cost of the device can be reduced.

Description

technical field [0001] The invention relates to an infrared visual detection device for cable aging position detection, which belongs to the technical field of electric power and infrared detection. Background technique [0002] The cable is usually made of two or more wires twisted, each group of wires is insulated from each other, and the outside is covered with an insulating coating. The cable has the characteristics of internal electrification and external insulation. [0003] This structure is beneficial to protect the cable and prolong its service life, but it still cannot completely avoid aging problems such as oxidation of the conductors in the cable. Once the wires in the cable have aging problems such as oxidation, it will affect the transmission function of the line, and in severe cases, the cable will fail. [0004] Aiming at aging problems such as wire oxidation in the cable, the service life of the cable is specified. After the service life is reached, the ca...
