Description

Technical Field

[0001] This utility model relates to a solid-insulated ring main unit. Background Technology

[0002] Solid-insulated ring main units (RMMs) are fully sealed high-voltage switchgear that uses solid insulation materials instead of traditional SF6 gas. Their core function is to distribute and control electrical energy. Existing RMMs lack a buffer structure between the door and the cabinet body during opening and closing. If the door is accidentally closed too close, the excessive impact can easily damage the door and internal components. The high-decibel noise generated by direct metal-to-metal collision can cause hearing damage to operators, resulting in a poor user experience. Improvements and optimizations are needed to address these issues. Utility Model Content

[0023] like Figure 1-10 As shown, the solid-insulated ring main unit of this utility model includes a ring main unit side panel assembly 1 and a ring main unit door 2 that is connected to the ring main unit side panel assembly 1. The ring main unit side panel assembly 1 includes a ring main unit side panel 4, a door buffer device 5, and a fixing plate 6 for installing and fixing the door buffer device 5. The ring main unit side panel 4 includes a side panel body 7, the front end of which is bent inward vertically to form a side panel mating part 8. The ring main unit door 2 includes a door body 10, the side end of which is bent inward vertically to form a door mating part 11 that contacts the side panel mating part 8. The door buffer device 5 includes a buffer seat 14, a rubber pad 15, a magnet 16, and a buffer spring 17. The buffer seat 14 has a main body cavity 20 divided by a first partition plate 19 and a second partition plate 18, and seat adsorption cavities 21 located at the upper and lower ends of the main body cavity 20. The rubber pad 15 is placed... Within the main cavity 20 of the seat body, the front end of the main cavity 20 is provided with a main clearance opening 22 for the rubber pad 15 to pass through. One end of the buffer spring 17 abuts against the rubber pad 15 and the other end abuts against the rear end of the main cavity 20 of the seat body. The magnet 16 is placed in the seat body adsorption cavity 21, and the front end of the seat body adsorption cavity 21 is provided with a seat clearance hole 23. The side plate connecting part 8 is provided with a side plate main through-hole 30 for the rubber pad 15 to make way during buffering and a side plate through-hole 31 for the magnet 16 to make way during adsorption. During the closing process of the ring network cabinet door 2, the door connecting part 11 first contacts the rubber pad 15. Under the action of the buffer spring, the impact force when closing the door is dissipated. At the same time, the magnet 16 guides the side plate connecting part 8 and the door connecting part 11 to connect accurately and smoothly. The buffer seat body 14 directly connects with the ring network cabinet door 2. The modular design is simple in structure and easy to install and disassemble the components, resulting in low cost.

[0024] The fixing plate 6 includes a fixing plate mounting part 33 fixed to the side plate body 7. The front end of the fixing plate mounting part 33 is vertically bent to form a fixing plate mating part 34 that fits against the rear end of the buffer seat 14. The fixing plate mating part 34 is provided with a fixing plate mating hole 35. The rear end of the buffer seat 14 is provided with a seat mating hole 40. The second partition plate 18 is provided with a seat internal threaded hole 41 at the rear end of the seat adsorption cavity 21. The screw passes through the fixing plate mating hole 35 and the seat mating hole 40 in sequence and is threadedly connected to the seat internal threaded hole 41. The connection is reliable and the screw action can ensure that the magnet 16 does not shift during the adsorption process, ensuring the stability and reliability of the adsorption.

[0025] The front end of the fixing plate docking part 34 is vertically bent to form a fixing plate wrapping part 36 that wraps around the upper end of the buffer seat 14. The rear end of the fixing plate mounting part 33 is vertically bent to form a fixing plate positioning part 37. The side plate body 7 is provided with a side plate positioning port 38 corresponding to the fixing plate positioning part 37, which effectively prevents the buffer seat 14 from shifting and ensures a firm and stable installation.

[0026] The first partition plate 19 is higher than the outer wall of the buffer seat 14, and the side plate body 7 is provided with a side plate anti-displacement opening 43 for limiting the first partition plate 19, thereby strengthening the connection tightness of the buffer seat 14.

[0027] The rubber pad 15 includes a rubber pad limiting part 44 placed in the main cavity 20 of the seat body and a rubber pad contact part 45 passing through the main clearance opening 22 of the seat body and contacting the cabinet door docking part 11. The rubber pad limiting part 44 is provided with a spring positioning groove 46 for positioning the buffer spring 17.

[0028] The magnet 16 includes a magnet limiting part 47 placed in the adsorption cavity 21 of the seat and a magnet adsorption part 48 placed in the clearance hole 23 of the seat, which effectively prevents the magnet 16 from falling off.

[0029] The cabinet door docking part 11 is provided with a cabinet door protrusion 12 that is aligned with the seat clearance hole 23, further enhancing the precise docking of the ring network cabinet door 2 and the ring network cabinet side panel 4.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
