Description
Technical field
The utility model relates to the lightning protection technical field, especially relates to the reinforced direct lighting stroke protective device of further minimizing direct lightning strike.
Background technology
With the formation of thunder and lightning, the explanation of majority's approval at present is: when the air motion thundercloud forms, often positive charge on top, and negative electrical charge is in bottom, about 1～4Km apart from ground.Form highfield between ground and cloud, its potential difference can reach 100,000,000 volts.
When above-mentioned potential difference can bear above the air ionization impedance, thunder and lightning just takes place, generally be that a thunder and lightning guide moves earthward in the early stage, be loaded with the very high quantity of electric charge, ground is formed highfield, its descending guide to ground the electric charge built on stilts (upward leader) of responding to a certain amount of opposite in sign and the thunder and lightning that descends is met, forms a passage and make electric charge scattering earthward on the thunder and lightning guide, fight back and generation heat energy and luminous energy so just produce.
The application in existing more than 200 year of Franklin conventional lightning conductor, it is a kind of device that thunder is gone into ground that draws, the popularization and application of lightning rod has reduced injury and the destruction of thunder and lightning to people, animal, thing greatly.
With lightning rod as the anti-thunder and lightning principle of arrester be: lightning rod inserts underground by earth lead.When charged cloud layer appearred in the sky, lightning rod utilized the height of self, and the thunder and lightning cloud electric field that makes electric field strength be increased to limiting value distorts, beginning ionization and descending guide discharge; Lightning rod produces point discharge under the highfield effect, form upwards guide's discharge; Both join and form the thunder and lightning path, spew out into the earth thereupon, reach lightning-arrest effect.In fact, lightning rod is an attracting thunder needle, thunder and lightning on every side can be attracted and discharge in advance, and the earthing conductor of lightning current by self passed to underground, avoids object of protection directly to be struck by lightning.On this basis, the nineties initial stage has been released the lightning rod (Fig. 1) that discharges in advance both at home and abroad again, and it is to utilize thundercloud to earth electric field, induced voltage in the device of lightning rod that discharges in advance, in the generation high-frequency and high-voltage concussion down that imposes a condition, make and produce the upward leader discharge in advance.The lightning rod that discharges in advance is the same with common lightning rod, also is to draw the notion that thunder is gone into ground.
The lightning arrester of direct striking thunder prevention electricity generally is made up of three parts, i.e. arrester, downlead and earth electrode; Arrester is divided into again connecing and dodges lightning rod, lightning conducter, lighting proof strip, lightning conduction.Usually above high-voltage line, adopted lightning conducter in the ultra-high-tension power transmission line.It is that commanding elevation by protection object (high-voltage line) connects to other commanding elevation and draws metal wire, and its protective action is equal to that every bit all is a contour lightning rod on lightning conducter.Since it connect that to dodge area big, connect sudden strain of a muscle equipment near space electric field intensity relatively strong, easier attraction thunder and lightning guide, near the probability that especially is struck by lightning than its low object making significantly reduces.
The conventional lightning conductor application table in more than 200 year in Franklin reveals its limitation: it can not solve thunder and lightning and go into the indirect lightning strike that produces in the ground process.
Have and use in the corona layer and the dissipation array device of thunder and lightning.Owing to damaged by thunderbolt, thereby negated by the user.
(patent No.: ZL200620115493.4 patent name: " anti-lightning backflash protective device ", its function is anti-lightning backflash to 2006 domestic utility model patents, can reach to prevent to take place in the protected district direct stroke.This CPD backflash protective device electric current through-current capability 65KA.The deficiency that its exists is " move to the thunder and lightning guide and descend the quantity of electric charge of region of discharge when being not enough to block towards the thunder and lightning guide that advanced by zone of protection ", exists the possibility that lightning backflash protective device is struck by lightning.This CPD backflash protective device electric current through-current capability 65KA.Therefore, this function is waited to research and solve.。
