Description

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large factories and 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 connections. Bus ducts have emerged as a new type of distribution conductor. They are a closed metal device composed of copper and aluminum busbars. They are used to distribute large power to various components of the distributed system. They have increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] When using existing bus ducts, due to environmental or work needs, multiple bus ducts need to be connected. When splicing, the metal conductor connecting plates between the bus ducts need to be docked first, and then the metal conductor connecting plates are fixed by bolts, and finally the bus duct protective covers are docked by multiple bolts. Therefore, when splicing the bus duct protective covers, the staff needs to tighten the bolts multiple times, which makes the installation more troublesome, thereby greatly reducing the convenience of the bus duct when connecting. In order to solve the above problems, we propose a fire-resistant bus duct that can be quickly docked. Utility Model Content
