In our daily life, we may not know much about modular data center, in fact, like cabinets, sealed channels, cooling systems, intelligent monitoring systems, etc., these combinations have become the modular data center in our mouth, then for the modular data center do you know its main components? Let me give you a brief introduction of its main components!
Modular data center is mainly composed of cabinets, closed channels, power supply and distribution system, cooling system, intelligent monitoring system, comprehensive wiring and fire protection system. The number of cabinets can be reduced in pairs according to customers' requirements. The composition of modular data center is shown in the figure.
The closed channel of modular data center mainly consists of end doors and skylights.
(1) End doors
The end doors of the closed channel are divided into two options: sliding doors and double doors, which can be matched according to the customer's needs.
Sliding door size: H×W×D = 2050mm×1600mm×42mm.
The sliding door adopts the sliding structure, takes the cabinet as the carrier and installs the upper and lower tracks to ensure the independence of the closed channel system itself. The door panel is bent from 1.5mm cold-rolled steel plate, and tempered glass is installed in the middle to ensure the visibility of the area inside the channel.
(2) Skylight
The enclosed passage adopts flat roof structure scheme.
Flat roof skylight size: H×W×D=350mm×1350mm×600mm.
The flat roof skylight consists of side panel, top panel and rotating skylight, with a single cabinet as the expansion module unit. The rotating skylight is connected to the top plate through FuseLink pins. The skylight is in a horizontal state under working condition, and the FuseLink is fused under fire fighting condition, and the skylight will open automatically under the action of gravity to ensure that the fire extinguishing gas enters the channel.
The modular data center has two types of power distribution schemes, including 380V/50Hz voltage system and 480V/60Hz industrial voltage system. The power supply and distribution system includes UPS (Uninterrupted Power Supply), PDF (Power Distribution Frame) and PDU (Power Distribution Unit).
1、Overview
Modular data center external power output through the UPS to the PDF, PDF output three-phase power to each cabinet PDU, PDU output power to the cabinet equipment .
2、UPS
UPS provides uninterrupted power supply for modular data center, when the utility/oil power supply emergency power failure, through the battery power supply, can meet the single server cabinet maximum power 9kW application scenario.
380V voltage system: modular data center configuration 360kVA modular UPS, consisting of three 120kVA UPS, can be flexibly configured within the capacity range of 20kVA ~ 360kVA, to meet the needs of single server cabinets 3kW, 6kW, 9kW.
480V voltage system: modular data center configuration 400kVA modular UPS, consisting of two 200kVA UPS, can be flexibly configured in the capacity range of 125kVA ~ 400kVA, to meet the needs of single server cabinets 3kW, 6kW, 9kW.
3、PDU
PDF cabinet with a power tester each way, used to measure the input three-phase AC parameters (voltage, current, frequency, power, power factor, etc.), uploaded to the monitoring system through the RS485 interface. PDF output open in accordance with the maximum 14 server cabinets in a single line configuration, to support the server power smoothly up to 9kW.
