Description

Technical Field

[0001] The present invention relates to the technical field of a primary and secondary fused complete ring network box, in particular to a high-reliability primary and secondary fused complete ring network box. Background Art

[0002] As an essential core device in distribution networks, ring main units (RMEs) are primarily used for energy distribution, conversion, and interconnection within urban power grids, industrial parks, and other areas, playing a key role in ensuring a stable power supply. Traditional RMUs consist of multiple compartments, each of which can house primary equipment such as circuit breakers, load switches, and fuses, enabling circuit disconnection and protection. In actual operation, when a line fault occurs, the RMU can isolate the faulty line by switching the interconnecting switch and redirecting power from other lines, thereby minimizing the scope of the outage and improving power supply reliability.

[0003] For example, the Chinese invention patent with application number 202311040008.6 discloses a ring mesh box that can dissipate heat from the box body. Under the action of the driving component, the fan blades rotate to draw air from the outside into the box body, thereby accelerating the air flow inside the box body and dissipating heat inside the box body. As the air circulates, the ventilation holes will gradually be blocked, so the ventilation holes need to be unblocked. At this time, the driving component controls the fan blades to reverse and blow air toward the ventilation holes, and under the action of the one-way transmission component, drives the rotating cleaning mechanism to move to drive the cleaning plate to move, thereby unblocking the ventilation holes. In order to ensure that the ventilation holes are fully unblocked, under the action of the adjustment mechanism, the cleaning plates are moved in directions away from each other to increase the cleaning area of ​​the ventilation holes and ensure that the ventilation holes are fully cleaned. However, the device still has certain defects; When cooling the ring network box, the cooling effect is achieved only through fans, which is relatively limited. Once the fan fails due to long-term high-load operation or dust accumulation, the circuit breakers, fuses and other equipment in the ring network box will continue to operate in a high-temperature environment, accelerating the insulation aging of electrical components, reducing the service life of the equipment, and even causing short circuits, tripping and other faults, which seriously threaten the safe and stable operation of the distribution network.

[0004] Therefore, we proposed a high-reliability primary and secondary integrated ring network box to solve the above problems. Summary of the Invention
