Center of 800V dc data builds: Distribution framework and equipment type selecting
As the flying development of IT, data center already became those who support contemporary company operation " cerebrum " . In pursuit efficient, green, safe setting falls, construction of center of 800V dc data becomes industry heat. The distribution framework that the article will construct around center of 800V dc data and equipment type selecting undertake be discussinged deep.
800V sheds the dominant position of data center continuously
relatively the communication data center at the tradition, center of 800V dc data has the following and distinct advantage:
1.Reduce loss: Dc system reduced the energy loss of the equipment such as transformer, switch, raised energy utilization rate.
2.Simplify framework: Dc system need not communicate complexly - dc changeover, simplified distribution framework, reduced construction cost.
3.Raise dependability: Because communication changes brought trouble to nod,dc system decreased, raised the dependability of data center.
4.Energy-saving environmental protection: Dc system reduced specific power consumption, conduce to the goal that achieves green data center.
Distribution framework is designed
The distribution framework design of center of 800V dc data should follow the following principle:
1.Modular design: Use modular design, facilitating system expands and safeguard.
2.Redundant design: Crucial equipment uses redundant design, the stability that ensures the system falls in the circumstance such as high load capacity, breakdown moves.
3.Security: Ensure the security of distribution system, prevent electric fire to wait for accident happening.
The 800V that is a kind of model below sheds framework of data center distribution continuously:
- input side: Use high-pressured dc to input, receive data center through ark of high-pressured dc switch.
- allocate side: Through dc allocation changeover of dc of ark general high pressure is low-pressure dc, allocate to each equipment.
- laden side: Each equipment accepts low-pressure dc system through module of direct current source.
Equipment type selecting
Type selecting of facility of center of 800V dc data should consider the following factor:
1.Power source equipment: Choose module of efficient, reliable direct current source, be like batteries group, UPS (UPS) etc.
2.Distribution facilities: Choose the dc distribution facilities of high-powered, small loss, if shed switch ark, dc distribution ark continuously,wait.
3.Supervisory equipment: The choice has real time monitoring, breakdown to diagnose functional supervisory system, ensure stability of data center security moves.
It is a few kinds of common equipment type selecting below:
- module of direct current source: Introduce high density, efficient batteries series, contented data center is right the steady demand of power source.
- dc switch ark: Use modular design, facilitate expand and safeguard, have the function such as overload protection, short circuit protection at the same time.
- dc distribution ark: Use the dc distribution device of high-powered, small loss, the safety that ensures power transmission process is medium and stability.
Conclusion
Center of 800V dc data builds the important way that is development of prospective data center. Through optimizing distribution framework and equipment type selecting, can enhance the energy utilization rate of data center, dependability and security. In building a course, enterprise should the element such as trend of mature technology development, cost effectiveness, choose appropriate plan, realize green, efficient, safe data center construction.
In the course that pursues data center construction, we are held to from beginning to end " green, efficient, safe " concept, provide professional, excellent service for the client. Believe to be in before long in the future, center of 800V dc data will be construction of our country informatization to offer prop up strongly.
