The Internet data center is the core hub of modern information technology. As a key carrier of massive data, it is not only a data storage center, but also a data circulation center and a core place for informatization. Its complexity and importance are self-evident.
The equipment in the computer room is diverse and sensitive. Transient overvoltage is one of the root causes of electronic system failures. They will spread in the building and damage sensitive equipment such as servers and storage racks, security systems, inverters and air conditioning equipment, causing irreparable losses such as communication blockage, so the protection of the data center is crucial.
Eyzao provides a comprehensive and efficient surge protection solution based on the characteristics of the data center computer room.
According to the IEC 62305 series of standards and GB 50174:2008 special protection requirements for data center rooms, the lightning protection zones of data center rooms and the installation and selection of SPDs must be determined by considering:
- Lightning protection zone (LPZ 0…3);
- Test current waveform that SPD complies with (8/20μs waveform and 10/350 μs waveform, etc.);
- Voltage protection level (UP value of SPD);
- Power supply system voltage and standard (230/400V and 400/690V systems, TN and TT, etc.);
- Harmonic interference, etc.
According to the standard
- IEC 623504″Lightning Protection” series of standards
- IEC 61312 “Protection against Lightning Electromagnetic Pulses”
- IEC 61643-11 “Surge Protective Devices Connected to Low Voltage Power Distribution Systems”
- GB 50174 “Design Specifications for Computer Rooms of Electronic Information Systems”
- GB 50057 “Lightning Protection Design Specifications for Buildings”
