Description

Technical Field

[0001] The utility model relates to the technical field of AC power supply cabinets, and more specifically, to an AC power supply cabinet which is convenient for maintenance. Background Art

[0002] AC power distribution cabinet is an important power distribution equipment in the power system. Its main function is to convert high-voltage electricity into low-voltage electricity and distribute it to various electrical equipment. In order to ensure the safe operation of the power distribution cabinet and the personal safety of maintenance personnel, it is usually necessary to install a protective plate on the power distribution cabinet. The function of the protective plate is to isolate the live parts to prevent accidental contact or short circuit. It can also play a role in dustproof, waterproof and rat-proof. However, there are some inconveniences in the existing installation method of the protective plate. In particular, when it is necessary to repair or replace components, the protective plate needs to be removed first. This process is often time-consuming and cumbersome, and special tools such as screwdrivers or wrenches are required. In addition, care must be taken not to damage the protective plate or other components during the disassembly process. This greatly reduces the efficiency and convenience of maintenance, prolongs the downtime of the equipment, and affects the normal power supply.

[0003] In addition to the installation and removal of the protective plate, the existing AC power cabinets also have some shortcomings in terms of wiring. There are usually a large number of cables and wires inside the power cabinet, which are used to connect various components and terminal blocks. The layout and fixing method of these cables directly affect the reliability and safety of the power cabinet. At present, many power cabinets use traditional bundling or binding methods to fix cables. This method is not only complicated to operate, time-consuming and labor-intensive, but also easy to cause damage or loosening of the cables. After long-term use, faults such as disconnection or short circuit may occur. Utility Model Content
