Abstract

The medical computed tomography (CT) technique cannot be directly applied to power equipment, such as gas-insulated switchgear (GIS), because of its huge size and immovability. In this research, a three-dimensional X-ray imaging system is developed for GIS equipment. The three-dimensional X-ray imaging system includes machinery, motion control, data acquisition, image reconstruction and three-dimensional image display subsystems. The principle of three-dimensional X-ray imaging is based on the Radon transform and the inverse transform. The rotary scanning device successfully collects 360 sets of projection data. The tomographic image is reconstructed using the acquired projection data. Shown in this paper is what is believed to be the world's first three-dimensional structure photograph of GIS that can be sliced and displayed using X-ray imaging. The application of the three-dimensional X-ray imaging system to the 110 kV GIS equipment at the Shayao Station of the Dongguan Power Supply Bureau shows that the overall accuracy of the system can reach up to 200 microns and the highest resolution of the output tomogram can reach up to 3160 × 3160 pixels.
