Information
At present, some old information network complex buildings mostly use centralized power supply. The general power equipment room is set on one floor, and the information load is on the upper floor. The distance between the power equipment room and the information load is too large, and the number of DC cables used in the information room is huge. On the other hand, there are some computer buildings that China Mobile and China Unicom use together. During the construction process, it is inevitable to lay cables through the China Unicom engine room. For example, China Mobile Switch House is on the fourth floor, while the power room is on the first floor, two and three. The layer is China Unicom engine room. In the implementation phase of the project, it is necessary to negotiate with China Unicom. Each construction needs to be negotiated once. Since the two companies are in a competitive relationship, communication and coordination difficulties are encountered, which affects the progress of the project.
 
In order to avoid excessive cable laying and coordination difficulties, it is recommended to use a one-time method to transfer DC power from the power room to the load room side. The dense busbar slot is used in the DC power supply system of the equipment room. It is a choice that can effectively reduce the cable usage. It has the characteristics of strong heat dissipation, environmental protection and flexible wiring. It has practical applications in the integrated building with centralized power supply mode. significance. At present, the solution has been increasingly used in the operator's computer room.
 
The busway is commonly used in the AC power supply system of high-rise buildings. The busway is a busbar system consisting of a metal plate (steel plate or aluminum-magnesium alloy plate), a protective casing, a conductive row, an insulating material and related accessories. The busway can be divided into air busbars, dense busbars and high-strength busbars according to the insulation method.
 
By analyzing the successful application of the busway in the AC system, the operator selects the dense insulated busway as the transmission medium of the electric energy in the DC power supply system, which can transmit the electric energy to the load side more reliably and safely.
 
The intensive busbar trunking busbar is produced by the factory, with guaranteed quality, small operation and maintenance workload, and simple construction and installation. In addition, the dense insulated busway housing is multi-point grounded, so that the housing is basically in the same potential grounding mode, which greatly simplifies the structure and eliminates the risk of personal electric shock.
 
Under normal circumstances, the DC power supply system consists of an AC screen, a rectification screen, and a DC screen. After the dense busway is used, the conventional DC power supply system needs to be adjusted: one or two large-capacity DC split screens are installed in the switch room, and a large loop output is set in the DC split screen; a mother is installed in the DC power supply system of the power equipment room. The joint screen, its function is the dedicated bus output, the output loop is not set in the cabinet; the DC split screen is connected with the mother screen by the dense busway; the DC head cabinet of the switch room is taken from the DC branch in the room. Screen.
