Abstract

The invention relates to an insulated thin-walled copper tube busbar. The busbar with a rated current of the insulated copper tube busbar below 8000A is suitable to use a copper tube with a wall thickness of less than 4mm as the busbar. Insulated copper pipe busbar with a wall thickness of 4mm copper pipe, the current density can reach 2.0 (A / mm2), the insulated copper pipe busbar wall thickness 3mm copper pipe, the current density can reach 2.5 (A / mm2), the insulated copper pipe busbar wall thickness 2mm copper tube, the current density can reach 3.0 (A / mm2), and then according to the voltage level of the bus, the copper tube is insulated and an insulating layer is added. The voltage level above 1kV needs to be shielded, and the surface potential of the insulating layer is zero. Make a metal protective shielding layer outside the insulating layer (the metal material is stainless steel, aluminum sheet, pipe, soft metal pipe).

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] [0005] Rated current temperature rise test (2) [0006] [0007] Rated current temperature rise test (3) [0008] [0009] Rated current temperature rise test (4) [0010] [0011] Rated cur...
