Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and in particular relates to a closed bus with built-in graphene. Background Art

[0002] The bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. In the indoor low-voltage power transmission trunk line engineering projects, it has increasingly replaced wires and cables. Plug-in bus ducts have emerged as a new type of distribution conductor. Compared with traditional cables, it fully demonstrates its superiority in large current transmission. At the same time, due to the use of new technologies and new processes, the contact resistance and temperature rise of the connection points at both ends of the bus duct and the plug-in points of the branch ports are greatly reduced, and high-quality insulating materials are used in the bus duct, thereby improving the safety and reliability of the bus duct and making the entire system more perfect.

[0003] At present, during the use of the existing closed busbar, since the busbar is in a closed state in the bus duct, the heat dissipation function of the busbar itself is limited and cannot achieve rapid heat dissipation. Most of the heat is transferred through the metal shell of the bus duct itself, which can easily cause the temperature in the bus duct to be too high, thereby causing damage to the busbar. For this reason, we propose a closed busbar with built-in graphene. Utility Model Content
