Abstract

The invention relates to equipment for detecting internal defects of a high-voltage cable. The equipment comprises a slide rail base; the cable butt joint mechanism is used for limiting the sliding rail base and the to-be-tested cable; the base plate is fixed on the sliding rail base, an arc-shaped guide rail is arranged on the base plate, and the arc-shaped guide rail is located in the radial plane of the cable to be detected; the radiation source mounting plate is movably mounted on the arc-shaped guide rail; the radiation source is fixed on the radiation source mounting plate; the driving part is used for driving the radiation source to rotate along the arc-shaped guide rail; and the detector is fixed on the radiation source mounting plate, takes the circle center of the arc-shaped guide rail as a boundary, is positioned on the opposite side of the radiation source, and can receive light rays irradiated by the radiation source. The internal defect detection of the high-voltage cable is realized by scanning the inner circumferential cone beam at a certain angle, the detection effect is good, and the efficiency is high.

Description

technical field [0001] The application belongs to the technical field of cable detection, and in particular relates to a high-voltage cable internal defect detection device. Background technique [0002] High-voltage cables are important carriers and tools for power transmission in today's society. Faults on high-voltage lines, such as short-circuits and discharges caused by ultra-high-voltage lines, occur from time to time, posing a great threat to people's lives and property. Therefore, it is necessary to carry out regular inspections on the transmission line, to keep abreast of the operation of the transmission line and the changes in the surrounding environment of the line, to discover and eliminate hidden dangers in time, and to prevent accidents. [0003] The inspection of high-voltage cables is a labor-intensive and wide-ranging task. At home and abroad, inspection personnel mainly rely on inspection personnel to use inspection equipment to perform inspection tasks a...
