[0002] In the prior art, the bus duct is a power supply system commonly used power transmission and distribution equipment. For a long time, when the bus is loaded, the bus temperature rises too high, and the skin effect is large, which causes the physical resistance of the bus conductor material to increase, thereby hindering and limiting the normal passage of current, resulting in power loss on the bus resistance and causing waste of national power energy.

[0003] A large amount of energy is consumed on the resistance every year around the world. We cannot change the physical properties of the conductor material, but we can change the conductor structure to control the physical properties of the material. The combined structure of the easy-to-heat bus has a significant physical heat dissipation effect when air convection cooling, mainly solves the problem of bus temperature rise, and prevents the bus resistance from rising to achieve the effect of physical consumption reduction.

[0015] The embodiments are further described in the preferred manner with reference to the accompanying drawings.

[0016] Reference is made to Figures 1-4 ​The present application mainly solves the following three problems: one is the easy heat dissipation busbar; one is the mutual embedding combination arrangement structure of the busbar; and one is the assembly structure of the combined energy-saving busbar duct.

[0017] 1. The easy heat dissipation busbar: the easy heat dissipation busbar is a busbar with a C-shaped conductor combined with fin structure, which is referred to as A-phase busbar 1, B-phase busbar 2, C-phase busbar 3 and N-phase busbar 4. The cross section of the busbar is a C-shaped conductor, and the upper and lower horizontal surfaces of the C-shaped conductor each have a plurality of fin structures. The unique structural advantage can achieve a large heat exchange area and a large convective heat transfer amount. In the air convection cooling, the physical heat dissipation effect is significant, so that the temperature rise of the busbar conductor is reduced to achieve the best physical properties.

[0018] 2. The mutual embedding combination arrangement structure of the busbar: the A-phase busbar 1 is embedded into the B-phase busbar 2, and the N-phase busbar 4 is embedded into the C-phase busbar 3, forming an embedding combination arrangement structure of the A-phase busbar 1, the B-phase busbar 2, the C-phase busbar 3 and the N-phase busbar 4. Thus, the horizontal and vertical conductive surfaces of the A-phase busbar 1 and the B-phase busbar 2 and the C-phase busbar 3 and the N-phase busbar 4 form a comprehensive phase-to-phase reactance cancellation and a combined arrangement of mutual reactance cancellation. This makes the combined energy-saving busbar duct have low reactance and resistance, and achieves the effect of physical consumption reduction when electric energy works.

[0019] 3. The assembly structure of the combined energy-saving busbar duct: the A-phase busbar 1 and the B-phase busbar 2 are fixed and insulated apart by the inter-phase insulation pad 9, the C-phase busbar 3 and the N-phase busbar 4 are fixed and insulated apart by the inter-phase insulation pad 9, and the bottom of the B-phase busbar 2 and the C-phase busbar 3 and the support frame 7 are fixed and insulated apart by the support insulation plate 8. After the combined bolt 12 is sleeved with the insulation pad 11 and the insulation sleeve 10, it is sequentially threaded through the A-phase busbar 1 and the B-phase busbar 2, the inter-phase insulation pad 9, the support insulation plate 8 and the support frame 7, and then installed on the upper surface of the support frame 7 by the fastening nut 13. After the combined bolt 12 is sleeved with the insulation pad 11 and the insulation sleeve 10, it is sequentially threaded through the C-phase busbar 3 and the N-phase busbar 4, the inter-phase insulation pad 9, the support insulation plate 8 and the support frame 7, and then installed on the upper surface of the support frame 7 by the fastening nut 13. The PE wire 5 is installed on the upper surface of the support frame 7 by the PE wire bolt 14. Finally, the support frame 7 is welded in the busbar duct shell 6, forming a combined energy-saving busbar duct.

[0020] After the above measures are taken, physical heat dissipation is achieved, the resistance of the busbar conductor is reduced, and the best physical properties and the best electrical performance are achieved. The problem of poor heat dissipation and large electric energy loss of the busbar duct has been solved for a long time, and the application prospect is wide.

[0021] The above Figures 1-4The application is shown in the preferred embodiment, showing the substantial features and significant progress of the application, and can be modified in shape, structure, etc. according to the actual use needs, under the technical inspiration of the application, but all within the protection scope of the technical scheme.
