Description

Technical Field

[0001] The invention relates to a bus duct, in particular to a bus duct which is convenient for positioning and protecting an internal conductive copper bar and a rapid assembly method thereof, belonging to the technical field of bus ducts. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of all walks of life has increased rapidly, especially the emergence of numerous high-rise buildings and large workshops. Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in bus ducts have emerged as a new type of distribution conductor. Compared with traditional cables, they fully demonstrate their superiority in high-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] Bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. It is generally made into a plug-in closed bus duct with connecting joints at intervals. The section where the conductive bar is located in the protective shell is generally wrapped with a layer of insulating material.

[0004] There are several conductive copper bars distributed inside the bus duct, which are used for conducting electricity between the bus ducts, so as to achieve the effect of electrifying the bus duct after connection;
