[0002] Electric power dispatching automation equipment is an automated system used in the power system dispatching center to monitor, control and manage power grid operations. These devices include computer systems, communication equipment, data acquisition and monitoring systems, energy management systems, dispatcher training simulation systems, etc. They can collect power grid operation data in real time, analyze and process it, and help dispatchers make quick and accurate decisions to ensure the safe, stable and economical operation of the power grid.

[0003] At present, electric power dispatching automation equipment needs regular inspection and maintenance to improve the stability of equipment operation. However, existing inspection staff generally need multiple people to operate collaboratively. It is often time-consuming and laborious to carry different inspection equipment to the construction site. In addition, it is inconvenient to take tools for inspection and maintenance after a fault is found, which affects the efficiency of inspection and maintenance. Based on these problems, Chinese patent CN114843915A discloses a maintenance device for electric power dispatching automation equipment. A first partition and a second partition are arranged in a cylinder, and an assembly cavity is formed between the first partition and the second partition. A multimeter tester is arranged above the first partition, an insulation resistance tester is arranged below the second partition, and a test pen and a test clip are arranged in the assembly cavity; an assembly port corresponding to the assembly cavity is arranged on the cylinder, and a transparent panel is arranged on the cylinder at positions corresponding to the multimeter tester and the insulation resistance tester.

[0004] When the device is in use, it can only detect and maintain the electric power dispatching automation equipment that the staff can access. When the equipment is installed at a higher position, it is not only difficult for the staff to detect and maintain it, but it will also bring many difficulties to the staff's work. Secondly, when the detection component and the maintenance component in the protective box move upward at the same time, the entire device will appear to be heavy on top and light on the bottom. At this time, the device is easily knocked over by external objects. Summary of the invention
