Surface defect scanning device for outer insulating sleeve

Abstract

The invention discloses a surface defect scanning device for an outer insulating sleeve, relates to the technical field of electric power inspection, and mainly aims to solve the problem that an existing scanning device is hard to comprehensively inspect the outer surface of the sleeve of electric equipment. The surface defect scanning device mainly comprises a clamp, a longitudinal moving device,an arc moving device, a leakage detector, a camera and a mainframe, wherein the leakage detector and the camera are mounted on the clamp, the clamp is mounted on the arc moving device, the arc movingdevice is mounted on the longitudinal moving device, the mainframe controls the longitudinal moving device to move vertically and controls the arc moving device to perform horizontal circumferentialmovement so as to scan and detect the cylindrical surface of the outer insulating sleeve through the leakage detector and the camera. By the surface defect scanning device, the observation of the surface defects of the outer insulating sleeve can be facilitated, and manual gas leakage detection can be replaced.

Description

technical field [0001] The invention relates to the technical field of electric power detection, in particular to a device for scanning surface defects of an outer insulating sleeve. Background technique [0002] The outer insulating bushing of power equipment is the insulating bushing that leads the internal high-voltage lead wire of the power equipment to the outside of the bushing, so that the lead wire is insulated from the ground. The bushing is often filled with transformer oil or SF 6 Gas acts as an insulating medium. When the outer surface of the bushing is dirty, the insulation is damaged, and rain flashes, creepage, etc. will occur. When there are cracks on the outer surface of the bushing or the flanges and joints are not well sealed, oil or air leakage will occur. The internal insulation is reduced, whether it is surface dirt or air leakage and other defects, it may cause accidents such as short circuit to ground and insulation failure of power equipment.

AI Technical Summary

Problems solved by technology

When the outer surface of the bushing is dirty, the insulation is damaged, and rain flashes, creepage, etc. will occur. When there are cracks on the outer surface of the bushing or the flanges and joints are not well sealed, oil or air leakage will occur. The internal insulation is reduced, whether it is surface dirt or air leakage and other defects, it may cause accidents such as short circuit to ground and insulation failure of power equipment

[0003] At present, the inspection of the casing mainly relies on infrared detection, naked eye observation, sound discrimination, etc. None of the above methods can scan the outer surface of the casing, which may easily lead to omissions or failure to observe, and the accuracy of naked eye observation and sound discrimination is not good. High, and it is difficult to accurately determine the location of the defect, the infrared imaging leak detector is not suitable for air leak detection in windy, night and other environments

It is difficult to realize a comprehensive inspection of the outer surface of the bushing in the existing equipment, which brings potential hidden dangers to the normal use of power equipment
