[Energy Conservation Institute] Comparative analysis of smart small busbar and column head cabinet solutions in data room

Introduction
In recent years, China's information technology industry has developed rapidly.Thanks to strong support from national policies, government finance, Internet companies, operators and other customers continue to build and upgrade data centers to match the growth rate of their data business.China's data center IT market has maintained a sustained and rapid growth trend.The vigorous construction and development of domestic data centers has also put forward higher requirements for its infrastructure.It is in this situation that the intelligent small busbar system of the data center appears and is gradually promoted.

Comparison of solutions
Before 2010, the cabinets in the computer room of the domestic data center were powered by the column head cabinet, and the column head cabinet was placed at the head of a row of IT cabinetsIt is used as a terminal distribution cabinet for power distribution and protection of one or more rows of IT cabinets.The column head cabinet usually uses the main circuit breaker UPS from the front end and then relies on multiple miniature circuit breakers and each miniature circuit breaker to energize the PDU terminal of the IT cabinet to form a data center.Generally speaking, the capacity of each column head cabinet is within 400A.

In recent years, with the rapid development of data center construction, traditional head cabinet solutions have been gradually replaced by intelligent small busbar systems.Compared with the traditional low-voltage busbar, the smart small busbar has the advantages of low current, convenient plug and high degree of intelligence. Its current specification is 630A within this range, which can meet the power distribution system of more than 90% of data center computer rooms in China.The intelligent small busbar from the front end through the end box UPS power transmission structure is composed of a busbar system of copper bar material, which adopts a plug-and-play method to distribute power to the PDU in each cabinet.The monitoring module is set in the head end box and the plug-in box, which can monitor the power consumption and temperature data of each cabinet, and has the function of communication to the dynamic ring monitoring.
Advantages of the smart small busbar solution
The smart small busbar has high flexibility
The traditional power distribution method of the head cabinet is to connect the power distribution column head cabinet after the UPS outlet cabinet, and then connect the equipment in each cabinet through cablespowered by.The radioactive power supply and distribution structure is adopted, that is, each cabinet is connected one-to-one with the cables of the column head distribution cabinet through cables, and the cables need to be re-discharged in the future.
Intelligent small busbar gets rid of the difficult wiring problem of traditional head cabinet, and the deployment is simple and quick.Deployment can be accomplished simply by installing the busway above all intended cabinets, and can be installed according to user access.It is not necessary to change the busway to increase the output capacity or the number of circuits of individual cabinets, just add or change the plug box, which can be plugged and unplugged with power.
Intelligent small busbar has quick investment and short construction period
Using track small busbar system to quickly install and deploy.For example, using the traditional head cabinet and cable mode, the typical construction period of the equipment room is about 40-50 days, which involves tedious processes such as distribution cabinets in place, cable tray installation, cable cutting and laying, and cable docking.It only takes 10-15 days to deploy the busbar system to complete the delivery of the machine room, saving a lot of construction time and labor investment, as well as the need for bridges and cables.Customers can deliver nearly a month in advance.
The safety of the small busbar system is higher and the service life is longer
Because the main structure of the small busbar is "aluminum alloy shell + grade B and above insulation sheath + copper busbar" On the one hand, the electricalGreater stability (including short-term withstand current and overload capacity): On the other hand, the entire busbar system has good heat dissipation, reasonably preventing the risk of short circuit caused by thermal accumulation, and greatly improving the service life.The service life of the busbar is about 30 years, while the service life of the cable is generally 10-15 years.
The busbar improves the utilization rate and income of the equipment room.
Because the busbar method is used to eliminate the need for the high-power column head cabinet, an IT cabinet can be added to the position of the original column head cabinet.Usually every 20 or so.The IT cabinet is equipped with a high-power column head cabinet. After removing the column head cabinet, the number of IT cabinets can be increased by about 1/20. Taking 1,000 cabinets in the computer room as an example, 50 head cabinets were originally required.The rental profit of each cabinet is 20,000 yuan/year, and the annual profit is 1 million yuan.
Therefore, as a rising star in the terminal power distribution of the data center computer room, the intelligent small busbar can gradually affect the traditional head cabinet solution and continue to grow at a rate of more than 20% per year.It is because of the above advantages.
