[0002] In recent years, with the rapid development of the national economy, the development of the power system has also ushered in a period of high quantity and high quality. Faced with the explosive growth in the number and types of power equipment, the contradiction in the power grid production field is manifested as the contradiction between the growing total number of equipment in the power grid and the zero growth of operation and maintenance personnel, and more importantly, the contradiction between the current relatively extensive operation and maintenance status and the urgent need for efficient and refined operation and maintenance during the transition period. Faced with the national call for "reducing costs and increasing efficiency", how to carry out efficient operation and maintenance management of equipment and how to improve the power supply reliability of operating equipment have become the main challenges faced by power grid companies. With the trend of substation operation and maintenance positions turning into "general practitioners", it is urgent to carry out live detection skills training for GIS equipment.
