Description

Technical Field

[0001] This utility model relates to a dual busbar type incoming line cabinet. Background Technology

[0002] The double busbar type incoming line cabinet is a type of high-voltage switchgear, which is equipped with two independent busbars (a total of 6 copper busbars) inside the cabinet. Each busbar can be connected to different power sources or loads. The existing double busbar type incoming line cabinet includes an incoming line cabinet body and an incoming line cabinet door. The incoming line cabinet door is connected to the incoming line cabinet body by a hinge. The hinge is not removable. When inspecting or maintaining the inside of the double busbar type incoming line cabinet, the cabinet door cannot be completely separated because it cannot be removed. It can only be opened to a limited angle. Maintenance personnel have to operate in a confined space, which may obstruct the view or limit the use of tools. It is particularly difficult to inspect the busbar connections and insulation components deep inside the cabinet. Improvements and optimizations are made to address this issue. Utility Model Content

[0020] like Figure 1-9 As shown, the dual-busbar type incoming line cabinet of this utility model includes an incoming line cabinet body 1 and an incoming line cabinet door 2 that is swayably connected to the incoming line cabinet body 1 via a hinge assembly 3. The incoming line cabinet body 1 includes a vertically arranged main beam 9. The hinge assembly 3 includes a door support plate 4, a door pointing component 5, a support spring 6, and a support plate mounting assembly 7. The door support plate 4 includes a horizontally arranged support plate receiving part 12, a support plate fixing part 13, and a support plate connecting post 14 riveted to the support plate receiving part 12. The front of the support plate receiving part 12 is provided with a spring receiving groove 15. The support plate fixing part 13 is... Part 13 is fixed to the main beam 9 of the cabinet body by the support plate mounting assembly 7. The cabinet door pointing component 5 includes a pointing component plate 17 fixed to the support plate receiving part 12. The support spring 6 is placed in the spring receiving groove 15 and its upper end abuts against the pointing component plate 17. The front of the pointing component plate 17 is provided with a pointing component arc sleeve 18 and a pointing component positioning post 19 sleeved on the upper end of the support plate docking post 14. The pointing component arc sleeve 18 is provided with arc sleeve cutouts 20 on both sides. The cabinet door 2 of the incoming line cabinet includes a cabinet door body 22. The lower end of the cabinet door body 22 is bent inward vertically to form the lower part 2 of the cabinet door. 3. The lower part 23 of the cabinet door is provided with a cabinet door positioning hole 24 that is opposite to the pointing member positioning post 19, a cabinet door limiting socket 26 for inserting the pointing member arc sleeve 18, and a cabinet door arc hole 25 that communicates with the cabinet door limiting socket 26 and is used for rotating the pointing member arc sleeve 18. The downward pressing of the cabinet door pointing member 5 provides cabinet door installation space. The pointing member arc sleeve 18 is much higher than the pointing member positioning post 19. The pointing member positioning post 19 is aligned with the cabinet door positioning hole 24. At the same time, the cabinet door limiting socket 26 of the incoming line cabinet door 2 is aligned with the direction of the pointing member arc sleeve 18 and inserted. Then the pointing member arc sleeve 18 is rotated. Insert the door into the arc hole 25 of the cabinet door, release the door guide 5, and the cabinet door 2 of the incoming line cabinet is installed and restricted. The cabinet door 2 of the incoming line cabinet can swing on the door guide 5. The same applies when disassembling the cabinet door 2 of the incoming line cabinet. The cabinet door guide 5 and the support spring 6 realize the detachable design of the cabinet door 2 of the incoming line cabinet, while ensuring the connection reliability of the cabinet door 2 after installation. The cabinet door 2 of the incoming line cabinet can be quickly assembled and disassembled. This design effectively solves the problem of traditional hinges not being detachable, so that the cabinet door 2 of the incoming line cabinet can be completely separated when needed, which greatly expands the operating space during maintenance and facilitates access to the busbar connection or insulation components deep in the cabinet.

[0021] The spring receiving groove 15 is provided with a support plate threaded hole 16, and the pointing plate 17 is provided with a plate recessed groove 28. The plate recessed groove 28 is provided with a plate through hole 29.

The installation is simple and ensures that there is no jamming on the contact surface, ensuring that the door of the incoming line cabinet 2 swings smoothly.

[0022] The support plate receiving part 12 is provided with the spring receiving groove 15 on the right side of the support plate docking column 14, and the support plate receiving part 12 is provided with the support plate positioning groove 30 on the left side of the support plate docking column 14. The back of the pointing plate body 17 is provided with the pointing part stabilizing protrusion 31 placed in the support plate positioning groove 30, which enhances the stability of the structure and the anti-shaking ability. The pointing part stabilizing protrusion 31 cooperates with the support spring 6 to ensure that the connection point can maintain stable contact even when the cabinet door is swinging, avoiding loosening or misalignment caused by cabinet door vibration or impact, and improving the overall safety and reliability.

[0023] The support plate mounting assembly 7 includes an upper fixing plate 10 and a lower fixing plate 11. Both the upper fixing plate 10 and the lower fixing plate 11 include a fixing plate mating part 34 that fits into the support plate fixing part 13. One end of the fixing plate mating part 34 is vertically bent to form a fixing plate mounting part 35. The fixing plate mounting part 35 is provided with a fixing plate mounting hole 36 for fixing to the main beam 9 of the cabinet. The upper fixing plate 10 and the lower fixing plate 11 are respectively disposed at the upper and lower ends of the support plate fixing part 13. The upper fixing plate 10, the support plate fixing part 13 and the lower fixing plate 11 are connected in sequence by rivets to ensure the stability and reliability of the connection between the cabinet door support plate 4 and the main beam 9 of the cabinet.

[0024] The other end of the fixing plate mating part 34 is bent vertically outward to form the fixing plate outer baffle 37, which enhances the structural support strength.
