Abstract

The invention provides a cable ageing position infrared-detection device based on heat-conducting property detection and belongs to the technical field of power and infrared detection. The cable ageing position infrared-detection device based on heat-conducting property detection comprises an upper annular ring, a middle annular ring, a lower annular ring and infrared cameras evenly distributed on each annular ring, wherein the upper annular ring, the middle annular ring and the lower annular ring are sequentially arranged from top to bottom, and output signals of the cameras are connected with a signal process. The cable ageing position infrared-detection device is characterized in that projection is conducted towards the cross section of a cable, the infrared cameras at the corresponding positions on the three annular rings are sequentially arranged at a fixed angle, and the upper annular ring, the middle annular ring and the lower annular ring do not have a rotating function. Compared with a power line ageing infrared-detection device and method of an invention patient, the complexity of the device can be simplified, detection steps can be omitted, and the device has the technical advantages of reducing the cost and simplifying usage by adopting the special structure of the cable ageing position infrared-detection device based on heat-conducting property detection.

Description

technical field [0001] An infrared detection device for cable aging position based on thermal conductivity detection belongs to the technical fields 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...
