Problems solved by technology

[0003] In addition, the defects of the original busbar: the insulation treatment of the busbar cannot be mechanized, the whole insulation process is made by hand, and the reliability of the insulation is difficult to guarantee. Since the length of the original busbar is within 13 meters, the busbar is rigid and cannot be bent freely, not like a cable continuous production on the production line
[0004] In addition, the compounding of the existing copper tube busbar and aluminum tube busbar has not yet realized the composite of metal and metal welding together, and the actual use of copper-aluminum tube busbar has not yet been realized.

Embodiment Construction

[0031] 1. As shown in Figure 1, the multi-split copper or aluminum busbar (pipe busbar) adopts multi-split conductors, and there is an insulating layer between the conductors, and each conductor has two conductive surfaces.

[0032] Example: ①The rated current is 3150A, the wall thickness of the copper pipe bus conductor is 3mm, and it is composed of two layers of 1.5mm conductors. There is an insulating layer between the conductors and the conductors. Diameter 90mm, cross-sectional area 820mm 2 , weight 7.3kg per meter, current density: 3.8(A / mm 2 ), temperature rise 40k.

[0033] Its (pipe bus) manufacturing method: according to the current carrying capacity requirements, select the appropriate thin copper or aluminum plate (thickness 0.1mm ~ 5mm), use the welded pipe production line to produce copper or aluminum pipes first, and then insulate the copper or aluminum pipes Treatment (according to the requirements of operating temperature, the selection of insulating materia...

Abstract

This invention relates to multiple split Cu or Al bus lines, in which, multiple split conductors constitute a bus pipe line, an insulation layer is set between two conductors and each conductor includes two conducting sides, 2, a rectangle bus line includes multiple conductors with insulation layers set in between and each conductor has two conductive sides and so on so forth, 3, each section of conductors of the Cu and Al strand cable includes an insulation layer in great carry flow, slow temperature-rising, light weight and energy-saving.

Description

technical field [0001] The invention relates to the use of power generation, power transmission and transformation, and power consumption units for conveying various voltage levels and large currents, and belongs to a new invention technology. Background technique [0002] The conductor material used for the existing high-current busbar is copper or aluminum, and the conductor shapes include tubular, rectangular, copper stranded wire, and aluminum stranded wire, and the above conductors are integral conductors. Example 1: The specification of the insulated copper tube bus bar with a transmission current of 3150A is Φ100mm×5mm, and the total cross-sectional area is 1491 2 , the total weight of the busbar per meter is 13.3kg, the current density: 2.1(A / mm 2 ), the temperature rise is 57k; Example 2: The conductor (copper bar) of a rectangular busbar carrying a current of 3150A, the specification width is 2×100mm×10mm, and the cross-sectional area is 2000mm 2 , the total weig...
