[0002] With the continuous development of power systems, the automation and intelligence of distribution networks are increasing. Integrated primary and secondary ring main units (RMUs), as important electrical equipment in distribution network systems, are widely used in urban power grids, industrial parks, and residential areas, primarily for the segmentation, interconnection, protection, and control of distribution lines. With the development of smart grids, higher requirements are being placed on the functional integration, operational stability, and ease of installation and maintenance of RMUs.

[0003] Existing integrated primary and secondary ring main units have several shortcomings that require improvement. Traditional ring main units typically use fixed installation for the terminals, making it impossible to adjust them according to on-site cable connection requirements, leading to wiring difficulties. Traditional ring main units also lack stable sliding guides and locking mechanisms, causing the terminals to easily shift after adjustment, affecting connection reliability. Furthermore, the slide rail installation method is relatively simple and difficult to adapt to different on-site installation environments. In addition, existing integrated ring main units lack effective cable routing structures, easily causing cable crossing and tangling.

[0004] In summary, existing integrated primary and secondary ring main units have significant shortcomings in terms of wiring flexibility, cable management, structural stability, and installation adaptability. Therefore, we propose an improved integrated primary and secondary ring main unit. Utility Model Content

[0033] The cable pass-through holes 9 on the L-shaped cable management rack 7 are used to pass cables through, allowing them to be arranged in an orderly manner, preventing them from getting tangled, and facilitating cable management and maintenance. A connecting rod is inserted into the connecting hole 8 to connect the comb rack connecting crossbar 6 and the L-shaped cable management rack 7, ensuring the stability of the entire cable management mechanism. Terminal blocks 10 are installed on the left side of the frame 2 inside the housing for connecting cables, and terminal wiring holes 11 provide interfaces for cable connections.

[0034] Terminal 10 is connected to a terminal sliding adjustment mechanism, and the adjusting sliding block 12 of the mechanism can slide on the sliding block sliding rail 13. The slider sliding buckle 14 at the top of the adjusting sliding block 12 cooperates with the slider locking groove 15. When it is necessary to fix the position of the adjusting sliding block 12, the slider sliding buckle 14 is engaged in the slider locking groove 15.

[0035] The U-shaped positioning groove 16 at the bottom of the slider locking groove 15 is used to install the sliding locking pad 17. The sliding locking pad 17 works together with the sliding clamping plates 18 on both sides of the adjusting slider 12. By connecting with the sliding guide grooves 19 on both sides of the sliding rail 13, the adjusting slider 12 can be stably slid and positioned on the sliding rail 13.

[0036] The elliptical keyway 20 on the outer plate of the sliding block slide rail 13 is used to install the sliding block slide rail 13 in a suitable position, ensuring the stable installation of the entire terminal sliding adjustment mechanism. By adjusting the position of the sliding block 12 on the sliding block slide rail 13, the position of the terminal 10 can be flexibly adjusted, facilitating cable connection and wiring.

[0042] Regularly inspect the appearance of the fusion ring network enclosure 1 for damage or deformation to ensure its protective function is normal. Check the sealing of the front panel 3 of the ring network enclosure and the flexibility of the panel handle 4. Check that the heat dissipation holes 5 are unobstructed and free from blockages to ensure effective heat dissipation. Check the arrangement of the cables in the cable distribution mechanism to ensure that the cables are not loose, displaced, or tangled. Check that the connection between the cables and the terminals 10 is secure and free from looseness or abnormal overheating. Check the operation of the terminal sliding adjustment mechanism, including whether the sliding block 12 slides smoothly on the sliding block slide rail 13, whether the sliding block latch 14 and the sliding block locking groove 15 cooperate well, and whether the connection between the sliding locking pad 17 and the sliding clamping plate 18 and the sliding guide groove 19 is stable. If necessary, clean and lubricate the sliding parts to ensure the normal operation of the adjustment mechanism. If any equipment malfunction is found during the inspection, such as damaged cables or loose terminals, repair or replace them promptly. For cases where the terminal position needs to be adjusted, operate according to the position adjustment method for the operating stage.
