Description

Technical Field

[0001] The utility model relates to the technical field of relay testing, in particular to a mobile relay protection testing platform. Background Art

[0002] Relay protection equipment plays a vital role in existing power systems. Its primary function is to monitor faults or abnormalities in the power system in real time and quickly issue signals or perform disconnection operations, thereby isolating and disconnecting the faulty component. This is a crucial protection mechanism for ensuring the continued normal operation of the power system. According to the operating procedures for relay protection equipment, a comprehensive inspection is required before commissioning. A corrective overhaul should be conducted in the second year of operation; a partial inspection in the third year; and a comprehensive inspection in the sixth year. Afterwards, regular maintenance is carried out according to this cycle mode. For example, a mobile relay protection test platform (publication number CN215768826U) is a representative prior art in the comparative document. This patented technology arranges wheels at the bottom of a hollow box body. The test line drawer, drawing drawer, power supply tray storage area and tool storage area are located on the same side of the box body. The upper side of the box body is provided with a tester placement area and a debugging notebook placement area. A drawing board and a screwdriver hanger are also provided on the side of the debugging notebook placement area. The tools and equipment for relay testing are integrated into a single platform, which is easy to move, has low labor intensity, is not easy to cause confusion in the lines, is safe and reliable during transfer, and is simple and convenient to operate, thereby effectively solving the problems of the prior art. However, its structure still needs to be improved, as follows:

[0003] In this solution, when the relay protection test platform performs inspection tasks on relay protection equipment, wheels are usually installed at the bottom of the box for easy movement. When only a few items are stored in the box, the overall mass is light and it is relatively easy to push. However, due to the heavy weight of the electrical equipment itself, when more objects are loaded in the box, its total mass increases significantly, making the pushing process time-consuming and labor-intensive. In addition, the height of the test platform is fixed and cannot be flexibly adjusted, which makes it difficult for testers of different heights and body shapes to maintain a comfortable working posture when performing relay protection tests, affecting the practicality and efficiency of relay protection tests. In order to better inspect relay protection equipment, a mobile relay protection test platform is needed to improve the above problems. Utility Model Content
