[0002] As an indispensable and important part of the power system, the distribution cabinet bears the important tasks of power distribution, control and protection. However, with the long-term use of the power system, the electrical components in the distribution cabinet will inevitably age and be damaged. This requires regular maintenance of the electrical components inside the distribution cabinet.

[0003] During the maintenance process, maintenance personnel usually need to put their hands or lean into the distribution cabinet for maintenance. Due to the small space and complex layout inside the distribution cabinet, and most of the electrical components are working with power on, if the maintenance personnel are not careful, they may touch the live parts, resulting in electric shock accidents, which seriously threaten their lives. After searching, the announcement number is "CN219874570U". The disclosed group of distribution cabinets with maintenance and protection against electric shock are carried out by manually pulling the connecting plate out of the main body of the distribution cabinet for maintenance and replacement, so that maintenance personnel can repair and replace the electrical components outside the distribution cabinet, thereby expanding the maintenance space and reducing the risk of electric shock. However, this design still has certain shortcomings. For example, when there are many electrical components installed in the distribution cabinet and the weight is too large, the operation of manually pulling out the connecting plate may become difficult; in addition, if the electrical components are not powered off in time before moving the connecting plate, there is still a potential risk of electric shock. Therefore, we propose an anti-electric shock distribution cabinet. Utility Model Content
