Abstract

The invention discloses an infrared detection device and a detection method for cable aging, which belong to the technical field of power infrared detection devices and methods. The infrared detection device for cable aging comprises the following elements arranged successively from the top to the bottom: an upper ring, a middle ring and a lower ring as well as infrared cameras uniformly distributed on the rings. The output signals of all cameras are connected to a signal processor; the infrared detection method for cable aging comprises: firstly, determining the horizontal location of aging; and then determining the axial position of the aging, and finally determining the spatial location. The detection method of the invention can rapidly find the aging position of a conducting wire in a cable without damaging the cable, which is favorable for replacing the aged cable and reducing the cost of the cable.

Description

technical field [0001] An infrared detection device and detection method for cable aging belong to the technical field of electric power infrared detection devices and methods. 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 cable will be replaced a...
