Description

Technical Field

[0001] The utility model is applicable to the technical field of copper tube busbar cooling, and particularly relates to a copper tube busbar cooling device. Background Art

[0002] At present, copper tube bus plays an important role in power transmission and distribution systems. It can provide reliable power supply and meet high load and high power requirements. When using it, copper tube bus is required for power transmission.

[0003] However, when copper tube busbars are used to transmit electricity, a large amount of heat will accumulate inside the busbars. In this process, as the heat accumulates, the high temperature will damage the insulation layer and reduce the service life of the tube busbars. The high temperature of the busbars will heat the metal conductors of the busbars, thereby reducing the mechanical strength. In addition, there are multiple groups of heat dissipation slots on the outside of the busbars, which cannot discharge the excessive heat. Therefore, we propose a copper tube busbar cooling device.
