Description
Technical field
The utility model belongs to technical field of electricity, relates to the servicing unit of a kind of network center machine room, particularly relates to a kind of Lightning Protection System about Network Center Machine Room.
Background technology
Thunder and lightning is a kind of very grand natural phenomena, and it has great destructive power, causes huge harm to the life of the mankind, property safety.The intrusion feature of lightning overvoltage is generally divided into several: 1, direct lightning strike, and thunder and lightning directly attacks on equipment in the open and causes damage.2, mine transmitting device, power line, signal transmssion line or the metal pipe line entering Control Room be struck by lightning or by lightning induction time, lightning wave invades equipment along these plain conductors, causes current potential official post device damage.3, induced lightening, when thunderbolt lightning rod, can produce very strong transient electromagnetic field around downlead.The watch-dog and the transmission line that are in elect magnetic field can induce larger electromotive force, and this phenomenon is electromagnetic induction.When there being charged thundercloud to occur, the building below thundercloud and transmission line all can induce the electric charge contrary with thundercloud.This charge inducing reaches 100kv at low-voltage overhead line Lu Shangke, can 40-60kv on signal line.This phenomenon is electrostatic induction.Electromagnetic induction and electrostatic induction are called induced lightening, are again secondary thunder.It does not have direct lightning strike suddenly to the infringement of equipment, but the probability that it occurs than direct lightning strike is much bigger.
Along with the develop rapidly of electronic technology in recent years, the networking degree of computer system is more and more higher, and the dependence of the mankind to computer network facility is more and more serious.The built-in a large amount of semiconductor integration module of these high-precision microelectronic computer network equipments, cause overvoltage, overcurrent protection ability extremely fragile, cannot ensure still can safe operation when being struck by lightning in specific space.
Network center's machine room is the hinge of network.Machine room, except suffering except direct lightning strike, is also likely destroyed by the lightning current transmitted along various circuit to machine room.If once there occurs device damage accident, just likely cause large area network paralysis, its consequence is very serious.But current existing lightning-protection system is difficult to carry out precision protection to the various sophisticated electronicses in machine room.
For this reason, needing specially is the lightning protection system that network center's Design of Machine Room is suitable, blocks all thunderbolt leaks, guarantees that the network equipment does not damage by thunder and lightning.
