Detailed implementation manners

[0020] The present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0021] As Figures 1-3 shown, the power distribution cabinet facilitating load interchange includes a rectangular frame 100, a three-phase busbar copper row 200, a vertical load plate 300, and a horizontal wire rack 400.

[0022] Specifically, the rectangular frame 100, as the framework of the power distribution cabinet, provides overall structural support and fixation. At the same time, the rectangular frame 100 is externally coated with a power distribution cabinet housing for protecting internal electrical components. The rectangular frame 100 includes a rectangular outer contour frame body and a plurality of first support crossbars 110 and a plurality of second support crossbars 120 connected horizontally to the rectangular outer contour frame body. The first support crossbars 110 are arranged close to the side walls of the power distribution cabinet housing, and the first support crossbars 110 are distributed at positions close to the left side wall, the right side wall, and the rear side wall of the power distribution cabinet housing. The second support crossbars 120 are arranged close to the top wall of the power distribution cabinet housing.

[0023] The three-phase busbar copper row 200 includes a phase A, a phase B, and a phase C, and is arranged in a directionally bent manner within the internal space of the rectangular frame 100. The three-phase busbar copper rows 200 are arranged in parallel at intervals and are bent in a U shape along the direction close to the left side wall, the top wall, and the rear side wall, effectively saving the space inside the power distribution cabinet, making the wiring work more convenient and efficient, enabling the busbars to adapt to the layout of the power distribution cabinet. There are ceramic insulating columns 210 between the three-phase busbar copper rows 200, and the three-phase busbar copper rows 200 are connected to the first support crossbars 110 on the left side wall, the first support crossbars 110 on the rear side wall, and the second support crossbars 120 on the top wall at corresponding positions through the ceramic insulating columns 210. The main function of the ceramic insulating columns 210 in the power distribution cabinet is to provide electrical insulation to ensure that no electrical short circuit or other arc discharge phenomena occur between the three-phase busbar copper row and the support crossbar, protecting the safety of personnel and equipment. The presence of the insulating columns also helps with heat dissipation, guiding the flow of hot air, thereby taking away the heat generated by the busbar copper row during operation. The outlet ends of the three-phase busbar copper row 200 are arranged horizontally.

[0024] There are two vertical load plates 300, which are arranged parallel to each other on the left and right and are vertically connected to the rectangular frame 100. On the vertical load plates 300, there are points for installing the load 500 from top to bottom; used to fix and support various load devices, usually fixed on the vertical load plates 300 by screws, and the load 500 faces the front door of the power distribution cabinet.

[0025] The horizontal wire rack 400, as Figure 4 shown, has a plurality of load bars 410 connected horizontally to the rectangular frame. Each horizontal wire rack 400 is arranged corresponding to the side of the point for load installation on the vertical load plate 300. On the left and right sides of the horizontal wire rack 400, there are three guiding components 420 each for guiding the wires between the load and the three-phase busbar copper row 200. The guiding component 420 includes a rotating column 421, the rotating column 421 has an external thread and is helically installed on the load bar 410 of the horizontal wire rack 400. The end of the rotating column 421 is connected with the guiding component 420. The guiding component 420 includes a first plate body 422 and a second plate body 423 connected to the rotating column 421. The semi-circular groove of the first plate body 422 and the semi-circular groove of the second plate body 423 form a round hole for guiding the wire after being overlapped. The first plate body and the second plate body are detachably connected by screws. The wire can be smoothly connected to the terminal of the three-phase busbar copper row 200, enabling the current to flow efficiently and safely. Through the rotating column 421 and the guiding component 420 installed on the load bar 410 by threads, the wire can be fixed and guided at variable angles, improving the flexibility of the wire layout and the convenience of maintenance. The semi-circular groove of the first plate body 422 and the semi-circular groove of the second plate body 423 of the guiding component 420 form a round hole for guiding the wire after being overlapped, making each wire orderly and avoiding chaos.

[0026] When a certain load device in the power distribution cabinet needs to be replaced, cut off the power supply and disconnect the relevant connections as required. For the wires that need to be replaced, unlock the corresponding guiding components and loosen the screw connections; adjust the direction and position of the wires by rotating the rotating column 421 as required; pass the wires that need to be replaced through the round holes of the guiding component 420 and reinstall them along the specified path; newly fix the guiding components to ensure the stability and orderliness of the wires; connect the new load device to the corresponding points to ensure correct installation. Connect the power supply and relevant connections: restore the power supply and reconnect the circuit connections related to the load device. Therefore, the power distribution cabinet facilitating load interchange has the characteristic of facilitating load interchange. The design of this kind of power distribution cabinet solves the problem of inconvenient load interchange. It provides a platform for supporting and fixing the load device, and wiring is carried out on the side close to the three-phase busbar copper row, ensuring the orderly layout of the wires. This makes the load replacement work simpler and more efficient, and does not require the participation of professional personnel and complex tools. Through the combined design of the vertical load plate, horizontal wire rack and guiding component, the utility model solves the problem that the load is not convenient to replace. The vertical load plate provides a supporting and fixing platform for the load device, and the guiding component ensures the orderliness of wire installation and wiring; at the same time, the detachable connection design of the guiding component facilitates the maintenance and replacement of wires, ensuring the flexibility and convenience of wiring. Such a design makes the load interchange of the power distribution cabinet more convenient and reliable.

[0027] The above embodiments are not limitations to the present utility model, and the present utility model is not limited to the above examples either. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model also belong to the protection scope of the present utility model.
