[0002] With the rapid development of social economy and the acceleration of urbanization, the demand for electricity is growing, which puts higher requirements on the reliability and stability of the power system. As an important part of the modern power system, box-type substations have been widely used in urban power grid construction and transformation, industrial production and temporary power use scenarios due to their compact structure, flexible installation and easy maintenance.

[0003] However, a major challenge faced by traditional box-type substations during operation is that when a transformer, high-voltage cabinet or low-voltage cabinet inside it fails, professionals are required to perform on-site diagnosis and repair. In order to ensure personal and equipment safety, it is usually necessary to power off the transformer, high-voltage cabinet or low-voltage cabinet. Since it often takes a long time for professionals to perform diagnosis and repair, this not only affects the continuity of power supply, but also increases maintenance costs. Summary of the invention
