Embodiment Construction

[0029] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing 1 .

[0030] As shown in Figure 1, the insulating thin-walled copper tube bus bar of the present invention, according to the requirement of carrying capacity, the bus bar adopts thin-walled copper tubes with a thickness below 4mm, and the copper tubes adopt cold drawing, and the specifications are as follows:

[0031] ①The 8000A busbar adopts copper pipe with a wall thickness of 4mm and Ф300mm.

[0032] ②The 6300A busbar adopts copper pipe with a wall thickness of 4mm and Ф240mm.

[0033] ③The 6300A bus adopts copper pipes with a wall thickness of 3mm and a diameter of Ф290mm.

[0034] ④ 5000A bus adopts copper pipe with wall thickness of 4mm and Ф200mm.

[0035] ⑤The 5000A busbar adopts copper pipe with a wall thickness of 3mm and Ф220mm.

[0036] ⑥The 5000A busbar adopts copper pipe with wall thickness of 2mm and Ф270mm.

[0037] ⑦The 4000A bus...

Abstract

This invention relates to insulation thin-wall copper pipe bus bar, in which, less than 4mm thickness of a copper wall is applied as the bus bar to the rated current of the bus bar under 8000A, and the current density can reach to 2.0(A/mm2) with 4mm thick of the wall of the bar and the current density can reach to 2.5(A/mm2) when the thickness is 3mm and the density can be 3.0(A/mm2) while the thickness of the bar is 2mm, then insulation process is done to the copper tube according to the voltage level of the bar, and the voltage level over 1KV needs shield process, potential of the surface of the insulation layer is zero and a metal protection shield layer is processed out of the insulation layer.

Description

technical field [0001] The invention relates to the use of substations and power plants for transmitting high voltage and high current in the technical field of power transmission and transformation, and belongs to a new invention technology. Background technique [0002] Existing high-current copper tube busbar conductors above 4000A, the current density is less than 1.5A / mm 2 , the waste of copper is particularly serious, the cost is particularly high, and the heat is serious. According to the comparison of the following five rated current temperature rise tests, the results can be obtained. The thicker the tube wall, the smaller the current density, the serious waste of copper, and the more serious the heat. [0003] Rated current temperature rise test (1) [0004] Test items results of testing Product Name: Insulated Copper Tube Busbar Model specification: Ф100×10×6000mm Loaded 2826 mm 2 Weight per meter: 25kg Test current: 4...
