Description
Technical Field

[0002] A ring main unit is an electrical device that is a group of high-voltage switchgear installed in a steel plate metal cabinet or made into an assembled interval ring main unit. Its core part uses load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. A ring network refers to a ring distribution network, that is, the power supply trunk line forms a closed ring. The power supply supplies power to this ring trunk line, and then distributes power to the outside through high-voltage switches on the trunk line. It continues to receive power from the left trunk line. In this way, although the total power supply is single-phase, each distribution branch gets benefits similar to dual-circuit power supply, thereby improving the reliability of power supply.
[0003] When the ring network box that is easy to maintain in the existing technology is in use, the ring network box without a tarp is directly exposed to rainwater, and its outer shell, internal electrical components and connection parts are easily corroded by rainwater, leading to problems such as rust, corrosion and short circuit. Rainwater intrusion into the ring network box may cause the electrical components to become damp, short-circuit or degrade the insulation performance, thereby causing electrical failure. After rainwater intrudes into the ring network box, frequent inspection and maintenance may be required, increasing the operation and maintenance cost and workload. Since the internal components may be damaged, the inspection process may also be more complicated and difficult. Therefore, we need a ring network box that is easy to maintain. Utility Model Content
