Embodiment

[0035] A copper-aluminum interface alloy composite conductor internal wave tube used in tubular bus ducts, such as figure 1 and figure 2 As shown, it includes an aluminum pipe 3 and a copper pipe 1 set outside the aluminum pipe. The side wall where the inner diameter of the aluminum pipe 3 is located is provided with several convex and concave waves 4 . The conductance of the inner wave expansion area of ​​the inner wave tube busbar is synchronized with the conductance of the outer surface. The efficient auxiliary section carries a large current, and the load heat dissipation performance is better.

[0036] Further requirements are made on the performance of the conductor to ensure the performance of the inner wave tube of the conductor. In one specific embodiment, the copper pipe 1 is a copper material of GB / T5231 national standard, and the copper content is not less than 99.9%. Made of. Further preferably, the aluminum pipe 3 is made of GB / T1196 national standard aluminum...

Abstract

The invention discloses a tubular busbar, especially a copper aluminum interface alloy composite conductor internal wave tube used in a tubular bus duct, and belongs to the technical field of power distribution equipment. The copper aluminum interface alloy composite conductor internal wave tube comprises a main conductor aluminum pipe and a copper pipe sleeved at the outer wall of the aluminum pipe; and the inner wall of the aluminum pipe is provided with a plurality of convex-concave wavelike convex strips. The copper aluminum interface alloy composite conductor internal wave tube used in the tubular bus duct provided by the invention greatly increases the conductivity of the inner surface of the conductor, reduces the temperature rise during current carrying capacity, and has a good heat dissipation and convection function, thereby ensuring the long load operation of the safety production of a large current tubular busbar.

Description

technical field [0001] The invention relates to a tubular bus bar, in particular to a copper-aluminum interface alloy composite conductor internal wave tube used in a tubular bus bar, and belongs to the technical field of power distribution devices. Background technique [0002] At present, the busbar conductor adopts a rectangular structure made of high-conductivity copper and aluminum materials. In actual work, this design method has the following problems: [0003] 1. Conventional busbar conductors have low load heat dissipation performance and high temperature rise when they are practical; [0004] 2. Conventional busbar conductors have a large power loss, which is not conducive to saving power and cannot make full use of power. [0005] Therefore, there is a need for a design optimized for the heat dissipation and power loss of the busbar conductors in use, so as to replace the traditional rectangular busbar. Contents of the invention [0006] The object of the pres...
