Abstract
The present invention relates to a fire-new lightning protection method and a device thereof. In the method, a protective top cover made of insulating materials with large resistance is used for the lighting protection of objects needing lighting protection, thunderbolt is led into the ground by traditional lightning rods, and inversely, thunderbolt is blocked outside the insulating top cover. The protective top cover of the device can be made of any insulation material such as epoxy phenolic laminated glass or other materials, can be attached to an insulating material or can be singly used. Cables in communication or Internet equipment can be protected by materials which are identical to materials of the protective top cover. The lightning protection of the method and the device is better than lightning protection devices in the prior art, and the present invention has better effect on induction thunderbolt.
Description
Technical field
The invention belongs to the shocking preventing technology field, relate in particular to insulation lightening arresting method and device.
Background technology
The thunder and lightning disaster is one of ten kinds of the most serious natural calamities of " the United Nations's IDNDR " announcement.
China is thunder country more than.Annual once, February audible thunder, still have thunderbolt to the November and take place.The thunder and lightning disaster has caused massive losses to national economy.Only according to Guangdong Province's incomplete statistics: in the period of 1996 to 1999 4,6143 of lightning strike accidents take place altogether, injures and deaths 699 people, 70 of fire, 1,500,000,000 yuan of economic losses.How lightning protection? till settled the present, the shocking preventing technology of traditional lightning protection theory may be summarized to be in short " draw thunder and go into ground " both at home and abroad.The rocket lightning protection of traditional lightning rod, lighting proof strip and up-to-date test, the laser lightning protection all is the road of " draw thunder and go into ground " of walking, proposed to use lightning rod from Franklin in 1750 and come in lightning protection 250 years till now, various lightning protection experts is studying " drawing thunder " problem with " going into ground " this respect.It is correct with the lightning rod to be that the theory of representative " draw thunder and go into ground " is undoubtedly, but there are the following problems in the practice:
The first, behind the dress lightning rod, near the lightning strike probability the protected district can increase greatly.Following example can illustrate:
The runway head on airport, Guilin in 1999 and airport, Liuzhou is struck by lightning, and I find that to field investigation the diameter in the hole of thunderbolt generally has only the 20-30 centimetre.Calculate that by this near probability that is struck by lightning building should be very little very little.But repeatedly thunderstruck situation in a year has but appearred in some station of having adorned lightning rod:
West suburb in Beijing airdrome synoptic station in 1998 is struck by lightning with regard to four times from the surface weather observation system that Finland introduces.An airport area is very big very big.Why always attack this area?
Eight observation stations that State Seismological Bureau in 1999 is provided with in the reservoir area of Three Gorges have five to be struck by lightning, and one of them station has suffered three thunderbolts in 1 year.The reservoir area of Three Gorges also is very big very big, and after this proved absolutely the dress lightning rod, lightning strike probability increased greatly.
The second, behind the dress lightning rod, the probability of protected district and near round indirect lightning strike thereof increases, and the intensity of induction thunder is also very big.Though protected building is not directly hit in thunderbolt, the internal electric device is destroyed.As:
June nineteen ninety-five, the command tower of Guangzhou's Baiyun International Airport on the 29th suffered thunderbolt to cause communication equipment fault, and the incident of seriously missing flight takes place, and the visitor that stagnates is up to ten thousand.
On June 20th, 1992 RSMC of Chinese weather bureau building thunderbolt, the building of lightning protection is intact, but mainframe computer and minicomputer network interrupt, and causes the meteorological newspaper of Chinese Central Television's next day to become blank.
No. 5 petroleum tanks in Qingdao City on the 20th Huang Island area August in 1989 are on fire because of thunderbolt sets off an explosion, and soon, No. 1, No. 2, No. 3, No. 4 oil tanks also cause and catch fire.Big fire has been burnt 104 hours fully, causes 19 people's death, and 78 people are injured, and economic loss is up to 7,000 ten thousand yuan, and the group investigation thinks that landing electromagnetic induction and the electrostatic induction that thunder produced is the unique real reason that causes big fire according to investigations.Above situation shows: over nearly 20 years, because the employing of large scale integrated circuit, the anti-thunderbolt ability of many electronic equipments weakens greatly, adds networked devices and increases, and outdoor circuit is crypto set more also, and these all are the true causes that very easily suffers indirect lightning strike.
Summary of the invention
Purpose of the present invention just provides a kind of brand-new lightening arresting method and shocking preventing technology.Make lightning protection effect be better than existing thunder resisting equipment.
The present invention finishes according to following technical scheme: because thunder and lightning does not have randomness with going into; it always looks for the passage of resistance minimum to go into ground (conventional lightning conductor is promptly according to this theoretical design) therefore; the present invention proposes to manage to strengthen resistance on protected object; the way that adopts insulation to isolate just can stop thunder and lightning " to go into ground ", has fundamentally eliminated and has drawn the possibility that thunder is gone into ground.
The present invention specifically adopts on protected building, installs big resistance insulation material protection overhead guard additional, and this protective top cap can be attached to above the Insulating frame, or supports with Insulating frame.
Beneficial effect of the present invention:
1. lightning-arrest effect is better than lightning rod, the lighting proof strip of prior art;
2. effectively reduce the probability of happening of induction thunder, to have large scale integrated circuit equipment place and internet, communication place, the lightning protection effect is better.
