As we all know, the lightning protection device is very powerful, it can enhance safety and prevent us from external damage. Next, let's explain the details of the lightning protection method of the PDU current device system.
We have learned that the signal lightning protection device is passively protected in the 0-level protection zone, mainly with lightning rods and grounding devices. Protection principle: When the thundercloud discharge is close to the ground, it causes the ground electric field to be distorted. At the top of the lightning rod, the inter-exchange electric field strength distortion is formed to affect the development direction of the lightning pilot discharge, guide the lightning discharge to the lightning rod, and then pass the grounding down conductor, and the grounding device introduces the lightning current into the earth, thereby protecting the protected object from lightning strikes.
Regarding the protection of the power supply part, the lightning infringement is mainly invaded through the power supply line. The "power surge protector" is connected to the power line to contain transient overvoltages and bleed surge currents. From the total incoming line to the end of the powered device, three levels of protection are usually configured. After step-by-step voltage limiting and discharging, the lightning energy is gradually eliminated to ensure the safety of the electrical equipment.
As for the signal part protection of the cabinet power supply, for various types of signal systems, it should be divided into rough protection and fine protection. The coarse protection level is determined according to the level of the protected area, and the fine protection is determined according to the sensitivity of the electronic device. After the "signal lightning arrester" is connected to the signal line, on the one hand, it is necessary to cut off the passage of lightning into the equipment, and at the same time, it must be able to discharge to the ground quickly. On the other hand, it must ensure that the signal through the lightning protection device is not under normal conditions. Damage, so that the equipment can work properly.
Processed in place. In the construction of computer rooms and various types of weak motor rooms, a good grounding system is required. Because all lightning protection equipment needs to discharge lightning current into the earth through the grounding system, thus protecting equipment and personal safety. If the grounding system of the equipment room is not well done, it will not only cause equipment failure, but also burn out the components, which will seriously endanger the safety of the workers.
In short, we have clearly explained the lightning protection method of the PDU current equipment system. We need to study and explore, continue to innovate, and promote the development of the industry better and faster.
