[0002] The functions of the main system in the electrical cabinet of subway vehicles are becoming more and more powerful, and the installation requirements are becoming higher and higher. When designing the electrical cabinet, it is necessary not only to consider the installation of the equipment, but also to consider the disassembly and wiring of the equipment after operation, so as to facilitate the later maintenance of the operating personnel and save maintenance time.

[0003] In the existing technology, the electrical cabinet equipment installation and maintenance structure fixes the electrical equipment inside the structure, fixes the equipment and the bracket by fixings, and fixes the equipment by installing an L bracket between the side mounting hole and the equipment mounting base, so as to facilitate subsequent maintenance and installation. However, in actual use, the electrical equipment is extremely inconvenient to install due to the different sizes of the electrical equipment, and when the connecting wires are installed with the electrical equipment, the connecting wires have no fixing devices, which can easily cause them to be detached from the electrical equipment during the dragging process, and the wires are crisscrossed inside the device, which can easily cause inconvenience in subsequent inspection and maintenance. In addition, the internal space of the electrical cabinet is limited, and the electrical cabinet can only be touched from the front. It is necessary to install an L bracket between the side of the equipment and the mounting hole and the bottom of the equipment for fixing. This structure first requires a large width direction to ensure construction space. At the same time, during later maintenance, the fasteners need to be loosened to take out the equipment and the bracket together, and the maintainability is poor. Therefore, it is necessary to improve a structure that facilitates the installation and maintenance of equipment in the electrical cabinet. Utility Model Content
