[0002] High-voltage ring main units (HNMUs) are key equipment in power systems used for distributing and controlling high-voltage electrical energy. They are widely used in urban power distribution networks, industrial facilities, and commercial buildings, providing crucial protection for the safe and stable operation of power systems. HNMUs, through their built-in switching devices, enable the opening and closing of power lines, ensuring the safety and reliability of power supply. They detect and isolate grounding faults, reducing the risk of electric shock and improving safety. Each functional unit is encapsulated in an independent chamber, reducing mutual interference and improving the overall reliability of the system. High-voltage ring main units use high-quality insulation materials to ensure electrical isolation between high-voltage components, preventing leakage and arcing. As a critical node in the power system, the HNMU undertakes the task of power distribution and control, directly affecting the stable operation of the entire system. Different projects have vastly different power load requirements, ranging from single users to large-scale industrial facilities or commercial buildings, requiring varying distribution capacities. By splicing multiple HNMU modules, flexible configuration can be made according to specific needs, avoiding resource waste. By rationally planning the location and size of each chamber, the limited space can be utilized to the maximum extent. The independent chamber facilitates inspection and maintenance, eliminating the need to disassemble the entire equipment and reducing downtime.

Rotating the rotating shaft causes the connecting fixing block to rotate, allowing one end of the connecting fixing block to rotate into the fixed slot, thus splicing and fixing the cabinets on both sides. When a cabinet needs to be removed for replacement, rotating the rotating shaft rotates the connecting fixing block into the rotating groove, facilitating the removal of the cabinet. The connecting block is then inserted into the connecting groove, and the rotating shaft is rotated again to rotate the connecting fixing block into the fixed slot, achieving the splicing of the cabinets on both sides. This simplifies the disassembly and assembly process, facilitating maintenance and replacement, ensuring a secure connection between the cabinets, preventing loosening or detachment due to vibration or other external forces, and improving system safety. Disassembly can be completed without tools, reducing operational difficulty and risk. The cabinets can be freely combined, enhancing the system's scalability and flexibility. Modules can be gradually added according to future electricity consumption growth, maximizing the use of limited space. Attached Figure Description

The insertion 4 slides into the limiting grooves 17 via the limiting blocks 14, and the self-locking mechanism of the insert 4 achieves [the desired effect]. The upper cabinet 1 can be quickly installed and fixed without tools, aligning and fixing the upper and lower cabinets 1, significantly shortening installation time, simplifying the connection steps between cabinets 1, reducing on-site construction time and labor costs, and improving installation efficiency. When it is necessary to remove the upper cabinet 1, push the pressing block 41 downwards to release the spring 31 and push the push block 3. The push block 3 pushes the cabinet 1 to facilitate the removal of the upper cabinet 1. The left and right cabinets 1 are then inserted into the connecting groove 13 through the connecting block 12 for splicing. The connecting block 12 slides... When the rotating shaft 21 moves to the bottom of the connecting groove 13, the rotating groove 121 aligns with the fixing groove 131, forming a circular structure. Rotating the rotating shaft 21 causes the connecting fixing block 2 to rotate, so that one end of the connecting fixing block 2 rotates into the fixing groove 131, thus splicing and fixing the cabinets 1 on the left and right sides. When the cabinet 1 needs to be removed for replacement, rotating the rotating shaft 21 causes the connecting fixing block 2 to rotate into the rotating groove 121, facilitating the removal of the cabinet 1. The connecting block 12 is then inserted into the connecting groove 13 and rotated.
