Abstract

The invention discloses a cable-aging-position detection method based on the temperature transferring rule, and belongs to the technical field of electric power and infrared detection. The cable-aging-position detection method based on the temperature transferring rule is differentially characterized in that a series of gray level data are obtained from six cameras on a middle annular ring, the difference between the gray level data of the two adjacent cameras is solved, six sets of difference data is obtained, the maximum value of the two adjacent or apart differences from the differences is selected, and the aging horizontal position is directly determined. Compared with The Power-Line-Aging Infrared Detection Device And Method, the calculating comparing judging step of the series of gray level data is obviously simplified; as the six cameras are evenly arranged on the middle annular ring, a one-sixth area can only need to be covered through each camera, the aging horizontal position can be determined in the one-sixth circumference range, and the detection accuracy is increased by one time.

Description

technical field [0001] A cable aging position detection method based on temperature transfer law 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 cable will be replaced as a who...
