Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to an outdoor ring network cabinet. Background Art

[0002] The ring main unit is a group of electrical equipment installed in a metal or non-metallic insulating cabinet or made into an assembled interval ring main unit. Its core part uses load switches and fuses, which have 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 load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises. The existing patent announcement number CN220475258U records a protective outdoor ring main unit, which includes a mounting plate and a cabinet fixedly connected to the top wall of the mounting plate.
