The company’s main product series have been widely used in multiple areas such as IDC building, cloud platform, communication network, medical field, national high-speed railway and railway transportation construction. It has long been the supplier and strategic partner of China Telecom, China Mobile, China Unicom, Radio and Television, Wasu Medica and is also the high-end products supplier for renowned brand such as Germany Rittal, Japan Toshiba, Holland Phillip, GE, Alibaba, etc.
IDC server rack is the carrier of user-hosted devices in the data center, and it is an important aspect in the IDC room building. IDC server racks are mainly used to place all kinds of user-hosted servers, routers and other active equipment, therefore they need to supply the power distribution equipment used by these devices, besides the good thermal performance, it also should be user-friendly service usage management.
The classification, characteristics and requirements of IDC server rack
——By frame structure: welded cabinets and assembled cabinets;
——By wind entering method: forward wind cabinet, bottom wind cabinet and top wind cabinet;
—— By power: AC cabinet and DC cabinet;
The main difference between welded cabinets and enclosures Assembled frame is welded inside the cabinet can be equipped with a complete installation package after delivery, more convenient post-construction; and the advantages of assembled cabinets that site assembly, parts delivery, saving packaging, transport costs;
Features forward wind cabinet before the wind for the mesh door or plain door, cold air from the front of the enclosure through the device, so the device cool down, this type of approach to be equipped with a cold air intake channel use; at the inlet of the cabinet is characterized by the front door closed steel doors or glass doors, air intake from the bottom of the cabinet to the cabinet interior air intake into the sealed space, the internal cooling equipment; diagram is as follows：
3.1 Environmental Requirements
Working temperature: -5 ℃ ~ + 40 ℃ Relative humidity: ≤85% (@+ 35 ℃) Atmospheric pressure: 76 ~ 106kpa Normal transport trains, ships, cars and aircraft and other transportation tools: transport. Packaged products can be adapted to normal conditions of transport, the situation is detrimental to the appearance and performance of the device does not appear.
Configuration Standard laminates or L-bracket.
3.3 Requirements of protection grounding and working grounding
The back or bottom of the cabinet by cabinet column should be set close to one for communication equipment protection grounding copper strips, ground copper strip cross-sectional area of not less than 36mm2, the cabinet and other metal parts inside should be reliable grounding device connectivity.
Ground copper strip 10-15pcs holes for 6mm2 copper lug.
3.4 Electrical performance requirements
Insulation resistance: between all live circuits or cabinet, insulation resistance of not less than 10MΩ.
Withstand voltage: between each live circuit or charging circuit of two non-cabinet and electrical connections, should be able to withstand 2500V, 50Hz sinusoidal test voltage 1min, no breakdown or flashover occurs, the leakage current is less than 10mA.
3.5 Cabinet seismic and load requirements
Cabinet load ≥800kg, base load ≥900kg;
The communication industry standard design, and meet the seismic requirements YD5059-2005. Cabinet should improve once according to local seismic intensity seismic fortification.
