[0002] Substations, as a crucial component of the power supply system, play a vital role in high-voltage power systems, primarily fulfilling functions such as voltage leveling, transmission line interconnection, and power transmission and distribution. However, the operation and management of substations presents certain safety risks, mainly due to the complexity of substation equipment, harsh environments, vast areas, and human factors. Traditional substation inspections rely heavily on manual labor, which is inefficient and risky in harsh environments; inspectors also depend on experience, potentially leading to missed inspections, misjudgments, or delays in handling issues. With the development of the power industry and the continuous expansion of the power grid, the importance of substations in the power system is increasingly prominent, and their safe and stable operation is fundamental to ensuring reliable power supply. Therefore, regular inspections of substation equipment to minimize equipment failures and avoid corresponding economic losses have become crucial.
