The Application of X-ray Digital Real-time Imaging Technology in GIS Defect Diagnosis

Gas insulated switchgear (GIS) is now a major product that is widely used by power system .The running state of GIS is very important for electric power systems because a power system failure will result in an enormous loss of life and property. X-ray imaging technique, which has been studied intensively for the past decades, can be very efficient tools for the application. X-ray digital real-time imaging technology is proposed for detecting GIS equipment. The internal defects of the equipment can be achieved by X-Ray digital real-time imaging technology in the case of without dismantling the device and electrification. Besides, the detection technology is a supplement and refinement to partial discharge detection methods. Moreover, it provides a basis for the condition-based maintenance and assistant decision-making of grid equipment.
