Solution of low voltage distribution in data center

The power distribution system of the data center distribues the power supply of the electricity, generator and UPS to the related load safely and reliably. Therefore, the power distribution system of data center should be designed according to the following points:

1, feasibility, distribution system is the complex of receiving and distributing power, its composition is influenced by many factors such as space, temperature, humidity and so on. It is necessary to consider the feasibility of distribution system in distribution system.

2, reliability, power supply reliability refers to the reliability of the power supply system uninterrupted power supply. The different reliability should be guaranteed according to the load level. In design, double accidents are not considered.

3. Safety and flexibility. The line of power supply system should ensure that operation and maintenance are convenient, and operation and maintenance are safe and reliable during normal operation and accident. To this end, we should simplify the line, reduce the level of power supply and operation procedures.

4, economy, the distribution scheme should be simple to meet the requirements of production and guarantee the quality of power supply, so as to reduce the cost of investment and operation, and to improve the safety of power supply.

5, forward-looking, the power distribution plan should ensure that it is easy to develop in the future, and at the same time, it can meet the needs of phased construction.

Based on the characteristics of the distribution system of data center and the experience of accumulating in the data center for many years, a complete set of data center distribution equipment is designed to meet the demand of all the electrical equipment used in the data center. It covers the front end receiving unit, the middle end feeding unit and the terminal power distribution unit.
