How to choose lightning protection cabinet PDU products for data centers?

The PDU lightning protection socket is designed for installation in standard cabinets. It mainly protects important equipment such as communication and electronics in the cabinet to avoid equipment damage due to overvoltage and lightning induction. This type of PDU perfectly combines a lightning protector with a power strip. It is equipped with multiple output jacks and is compatible with plug standards of many countries. It can protect multiple power supplies at the same time. It is safe and reliable to use, simple and convenient, and has replaceable lightning protection modules and easy maintenance. Etc.

With the development of modern science and technology and the progress of society, various industries are constantly introducing and using a large number of advanced automation control equipment, office networks, and industrial television monitoring systems, and the systems are becoming more and more complex and intelligent. . As the cornerstone of promoting digitalization, data centers ensure information transmission and data storage. Whether social networks, entertainment, public health, energy, telecommunications, transportation or government agencies, they are inseparable from the services provided by data centers.

However, a data center containing a large number of integrated circuits and precision microelectronic devices is a relatively fragile system. Due to the increase in the integration of these devices, the withstand voltage level is reduced, and it is very sensitive to operating overvoltage and electrostatic interference, lightning strikes and surges. The resulting overcurrent, overvoltage effects or even breakdown. According to statistics and research, in actual operation, more than 60% of electronic and electrical equipment suffers from data loss, malfunction, crash, malfunction or even damage, which is related to operating overvoltage and electrostatic discharge.

There are two main sources of surges in the power supply and distribution system inside the data center:

(1) Transient surges caused by direct lightning strikes or induced lightning strikes;

(2) Operation overvoltage in the power supply system caused by dual-channel power switching and short circuit.

Therefore, lightning protection in data centers is very important. Currently, the internationally mainstream classification of data center computer rooms is the Tier level standard formulated by the American company Uptime Institute. The Tier level standard is divided into four levels, namely Tier I, Tier II, Tier III, and Tier IV. Tier IV is The highest level, but a level that is divided into design certification and construction certification. my country's "Electronic Information System Room Design Standard" (GB50174-2021) stipulates that my country's data centers can be divided into four levels: A, B, C, and D based on the nature of use, governance requirements, and their importance in the economy and society.

Level A: Fault-tolerant type, which means that during the period when the system needs to run, its site equipment should not cause the operation of the electronic information system to be interrupted due to operating errors, equipment failures, external power interruptions, maintenance and repairs. It is the highest level, such as the national information center, Computing centers, bank head offices, emergency command centers, etc. all fall into this category. Level B: Redundant type, which means that during the period when the system needs to run, its site equipment is within the redundancy level, and the operation of the electronic information system should not be interrupted due to equipment failure, such as universities, tertiary hospitals, and provincial and ministerial offices. Buildings, large and medium-sized city meteorological stations, etc. belong to Class B computer rooms. Level C: basic type, which means that when the site equipment is operating normally, the electronic information system should be guaranteed to operate without interruption. Class D: General-purpose electronic information equipment other than Class A, B, and C.

For data centers, we generally focus more on Class A national computing centers and Class B medium-sized computing centers. As shown in the figure below, Class A lightning protection is divided into four levels, and Class B lightning protection is divided into three levels. Levels are rated according to the nominal discharge current of the lightning protection device. As shown in the table below, Class A lightning protection In is divided into four levels: 80kA, 40kA, 20kA, and 10kA.

According to relevant standards, the placement locations of the four levels of lightning protection facilities under Level A are as follows. Among them, LP4 should be placed on the PDU, In=10kA.

By using lightning-proof PDU cabinet sockets, it can prevent overload and high temperature, lightning strikes, surges and other hazards, and maximize the safety factor of server products in data center computer rooms. At the same time, the combination of lightning protection and anti-surge functions with communication, storage, and control modules can also realize the Internet of Things for lightning protection cabinet PDU products, helping users achieve unattended operation, save labor costs, and effectively reduce management and maintenance costs. Great value for money.
