Applying X-ray inspection technology, achieve precise and visualized judgment for power equipment status in power grid.
With the continuous development of non-destructive testing methods, using X-rays to conduct non-contact non-destructive testing on equipment can observe structural abnormalities inside the equipment under live operation conditions. The test results are intuitive and accurate. X-ray inspection technology can accurately identify mechanical defects inside the closed shell of gas insulated substation (GIS) equipment, successfully detecting defects such as damaged closing resistors, broken spring contacts, and internal detachment of polytetrafluoroethylene strips in ultra-high and extra-high voltage GIS, effectively avoiding main equipment failure trips and ensuring reliable operation of the equipment.
Inspection personnel can use portable X-ray digital imaging inspection equipment to accurately, efficiently and visually identify typical defects such as incomplete opening and closing, foreign objects, loose bolts and component fractures inside GIS. Through safe and reliable on-site inspection standards, standardized defect classification diagrams, high-resolution X-ray imaging image enhancement software, miniaturized and lightweight inspection devices, automated inspection processes, intelligent automatic defect recognition, X-ray inspection analysis platform AI inspection and remote expert re-inspection, the quality and efficiency of inspection technology can be improved simultaneously.
A variety of digital flat panel detectors and X-ray sources can be combined to achieve refined applications in different scenarios:
7MeV betatron with flat panel detector, high-energy betatron X-ray DR system, ultra-high voltage GIS substation combined electrical apparatus.
300kV high-frequency constant voltage directional portable radio-graphic machine with flat panel detector, 300kV high-frequency portable X-ray flaw detector DR system, suitable for internal foreign object defects, component defects, and poor assembly processes of GIS circuit breakers, disconnectors, grounding switches, busbars, and current transformers.
270kV ultra-light pulsed X-ray machine with flat panel detector, pulsed portable X-ray source DR system, internal cavity defects of porcelain insulators or core rod defects of composite insulators can be detected by X-ray inspection of tension clamps on transmission lines carried by drones.
