Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, and more specifically, to a splicing mechanism of a ring network cabinet. Background Art

[0002] The ring main unit is a group of electrical equipment (high-voltage switchgear) 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 urban residential areas, high-rise buildings, large public buildings, factories and enterprises and other load centers. Usually, the ring main units are assembled and connected to make assembled interval ring main unit, but most of the existing ring main units do not have the function of fixing peripheral connections. Since the ring main unit cannot be fixedly connected, it is very inconvenient to connect and assemble the ring main unit, making it impossible to effectively assemble the ring main units together. Therefore, we have made improvements to this and proposed a ring main unit. Utility Model Content
