We are still using traditional power supply systems in some parts of the project,which can make the project very complex,especially in high-rise buildings where power demand is high.To avoid excessive cable laying and coordination difficulties during the use of bus ducts,it is recommended to use a one-time method to transfer DC power from the power room to the load room side.To meet the requirements of such projects,it is necessary to use bus ducts.Today,we will talk about the many conveniences that bus ducts bring to the power system.

　　The use of bus ducts in high-rise buildings allows for easy wiring and simplifies the entire power system,making the building more aesthetically pleasing.Secondly,bus ducts have strong safety performance due to their unique structural characteristics.The use of blocked bus ducts in the DC power supply system of the computer room is an effective way to reduce the usage of cables.It has the characteristics of strong heat dissipation,environmentally friendly products,and flexible wiring.It has practical application significance in comprehensive buildings with centralized power supply mode.Provided support for large-scale power systems.Moreover,it is important to note that the use of bus ducts does not increase the cost of the project.On the contrary,when calculated from the overall work schedule,the use of bus ducts is a more cost-effective way,so it is worth promoting vigorously.

　　Bus duct is commonly used in the AC power supply system of high-rise buildings.Bus duct is a bus system composed of metal plates(steel plates or aluminum magnesium alloy plates)as protective shells,conductive bars,insulation materials,and related accessories.Bus ducts can be divided into three types according to insulation methods:air type bus ducts,dense insulated bus ducts,and high-strength bus ducts.By analyzing successful application cases of bus ducts in AC systems,operators choose dense insulated bus ducts as the transmission medium for electrical energy in DC power supply systems,which can more reliably and safely deliver electrical energy to the load side.Install one or two high-capacity DC split screens in the exchange room,and set up large circuit outputs inside the DC split screens;Install a busbar in the DC power supply system of the power room,which functions as a dedicated busbar output and does not have an output circuit inside the cabinet;Connect the DC split screen to the bus tie screen using a closed bus duct;The power supply of the DC column head cabinet in the exchange room is all from the DC distribution screen in this room.

　　The enclosed busbar is produced by the manufacturer as a complete set,with guaranteed quality,low operation and maintenance workload,and easy construction and installation.In addition,the dense insulated bus duct shell adopts multi-point grounding,which makes the shell basically in an equipotential grounding mode,greatly simplifying the structure and eliminating the risk of personal electric shock.In general,a DC power supply system consists of an AC screen,a rectifier screen,and a DC screen.After adopting a closed bus duct,adjustments need to be made to the conventional DC power supply system.
