Abstract
GIS is widely used in high voltage transmission and transformation system due to its small area and good insulation performance. As an important component of GIS, basin insulators play the role of supporting conductors, isolating gas chambers and electrical insulation. If there are cracks, bubbles and other defects in the basin insulator, partial discharge will be caused, which seriously threatens the safe and stable operation of the equipment. In order to conveniently and timely detect the cracks and bubbles of basin insulator, the GIS imaging method enhanced by laser focused ultrasound is proposed. This method can not only detect defects but also image, providing intuitive image information for power grid operation and maintenance personnel.
