Lightning wave intrusion is due to the action of lightning on overhead lines or metal pipes, lightning waves may invade the room along these lines, endangering personal safety and damaging equipment. According to lightning electromagnetic pulse protection theory and practical experience has proved that the main cause of damage to electronic information equipment is caused by lightning induced surge voltage. It can be introduced into the electronic information equipment through a variety of leads induced surge voltage waves inside, damaging its chips and interfaces.
Data centers pay great attention to the continuity of the power supply, so lightning protection can not be ignored, the better performance of the network equipment itself comes with lightning protection, in the power coming in on the line, there is used to absorb high-voltage surge line design. Although the product with lightning protection, but the lightning generated by the induced voltage of several thousand volts or tens of thousands of volts or even higher, regardless of which brand of router, the router alone comes with its own lightning protection function may only solve part of the harm caused by lightning, want to further reduce the harm caused by lightning should be equipped with the appropriate lightning protection equipment.
Should be installed independent lightning rod or overhead lightning line, is protected by the building and the wind cap, dispersion pipe and other objects protruding from the roof are in the scope of protection of the flash catcher.
Discharge of explosive hazardous gases, steam or dust dispersion pipe, breathing valve and exhaust pipe outside the mouth of the following space should be in the scope of protection of the flash catcher.
Independent lightning rod of the tower, the end of the overhead lightning line and overhead lightning network at each pillar, should be set up at least one lead wire. For made of metal or welded, tied to connect the steel tower, pillar, to use it as the next lead.
Independent lightning rod, overhead lightning line application independent grounding device, each lead wire impact grounding resistance should not be greater than 10 Ω. In areas of high soil resistivity, can be appropriate to increase the impact grounding resistance.
When the tree is higher than the building and not within the scope of the flash catcher protection, the net distance between the tree and the building should not be less than 5cm.
