Description

Technical Field

[0001] The utility model relates to the technical field of application of intensive bus ducts, in particular to a direct current bus duct based on an intensive structure. Background Art

[0002] The DC bus duct is a distribution equipment used for power transmission. It is mainly used to install and protect cables or copper bars. The main function of the bus duct is to enclose the distribution cables therein, thereby protecting the cables from the influence of the external environment. At the same time, it is also for safety reasons to prevent electric shock accidents. In the AC power supply system of high-rise buildings, bus ducts are particularly common. The use of bus ducts can reduce line losses and improve the transmission efficiency of electric energy. Therefore, they have certain advantages in terms of economy. At the same time, they can meet the high standards required in special scenarios.

[0003] When the existing bus duct is in use, the copper bar inside it will generate high temperature when it is powered on. Therefore, the traditional heat dissipation method generally uses a heat conduction cooling treatment method, which causes the high temperature generated inside to not be discharged in a timely and effective manner, reducing the service life of the bus duct. At the same time, when the bus duct is hoisted, installed and fixed, it is generally connected and fixed with a large number of bolts and screws, which makes the work operation of the staff more cumbersome, thereby reducing the installation efficiency of the bus duct. Therefore, the utility model proposes a DC bus duct based on a intensive structure. Utility Model Content
