Its core part adopts load switch and fuse, which has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in urban residential areas, high-rise buildings, large public buildings, factories and enterprises and other load centers.

[0003] After searching, the existing patent (publication number: CN220605307U) discloses an outdoor ring network cabinet that is easy to repair. During use, the internal cables are fixed by the limit mechanism and the limit hole on the baffle to prevent the cable installation from being affected by the pulling process when the installation plate is pulled out for maintenance, causing the cable interface to loosen. However, the inventor found that the prior art has the following problems in the process of realizing the utility model: in order to meet the effect that the installation plate can be pulled out to facilitate maintenance, the above-mentioned outdoor ring network cabinet that is easy to repair needs to reserve extra length for the cable when the electrical equipment on the surface of the installation plate is installed with the cable to meet the needs of the pulling and pulling activities of the installation plate. However, the above-mentioned ring network cabinet lacks a structure for storing the reserved length of cables, resulting in some cables being scattered inside the ring network cabinet during use, causing the internal lines of the ring network cabinet to be arranged irregularly, and then hindering the maintenance work of the staff during the subsequent maintenance of the cabinet body.
