Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and in particular relates to a bus duct connection device. Background Art

[0002] Busbar ducting, as an efficient and flexible power distribution system, is widely used in high-rise buildings, industrial plants, and large-scale facilities. It utilizes copper or aluminum busbars as conductors, enclosed within a metal casing, creating a continuous current path that effectively reduces power transmission losses and electromagnetic interference. Busbar ducting offers a compact design and easy installation, adapting to various complex wiring requirements and enhancing the overall aesthetics and safety of the distribution system. Its modular design facilitates future maintenance and expansion, meeting the demands of power load growth at different stages.

[0003] Chinese patent publication number CN210092815U discloses a copper-aluminum alloy busbar duct having a metal shell and a conductive bar, the conductive bar including a plurality of aluminum conductive sheets arranged side by side. An electrical insulating medium is provided within the metal shell for achieving electrical insulation between the aluminum conductive sheets and between the aluminum conductive sheets and the metal shell. The aluminum conductive sheet comprises a main section located within the metal shell, a connecting section located outside the metal shell, and a bent section connecting the main section and the connecting section. Transition connecting sheets are provided on both main surfaces of the connecting section. The transition connecting sheets include an aluminum foil layer and a copper foil layer stacked on the aluminum foil layer. The aluminum foil layer is resistance-fused-welded to the aluminum conductive sheet, and the sum of the thickness of the connecting section of the aluminum conductive sheet and the transition connecting sheets located on both sides of the connecting section is equal to the thickness of the main section of the aluminum conductive sheet.

[0004] Although the copper-aluminum alloy bus duct in the above-mentioned prior art can basically meet the connection and installation requirements between bus ducts, there are still some shortcomings in actual use. For example, traditional bus ducts are generally fixed with a single bolt during connection, which has low installation strength, weak stability, and a single structure and function, and cannot provide more effective heat dissipation protection for the busbar.

The symmetrical double fixing bolt structure used in this structure can greatly ensure the stability and strength of the connection between the busbar bodies.

[0018] Second, by opening the first ventilation slot and the second ventilation slot on the aluminum cover, the ventilation and heat dissipation effect of the aluminum cover can be improved. By using the aluminum sheet corresponding to the second ventilation slot, the heat dissipation surface can be expanded to further improve the heat dissipation effect. At the same time, the ventilation holes on the aluminum sheet corresponding to the first ventilation slot can further enhance the heat dissipation effect of the aluminum cover on the busbar body.
