Abstract
The utility model relates to a grid-shielding lightning device, which comprises six (3-18) metal circular fencing curtain rods, a circular arc-shaped grid cover and an earthing device. The utility model is made by using the poly-skin effect principle and the shielding principle. The utility model is characterized in that the metal circular fencing curtain rods approximately forming cylindrical barrels are connected with fencing curtain lines, the top of each metal circular fencing curtain rod is connected with the circular arc-shaped metal grid cover, and the bottom is connected with a copper plate and a charcoal powder earthing device. The utility model integrates the cylindrical grid barrel, the circular arc-shaped grid cover and the earthing device, has the advantage of the 100% reliability of the lightning shielding and is suitable for being used for various power devices, telecom devices, television and electric appliances and other crowding locations of people and livestock.
Description
The utility model relates to a kind of grid-shielding lightning-shielding device
Along with developing rapidly of electric power, telecommunications, TV tech, the application of lightning arrester is very extensive.Adopt the lightning rod utilize the point discharge principle to make for a long time always, neutralize and reach relative lightning-arrest in the certain limit by drawing thunder and lightning energy and the earth, modern age, rocket drew the success of thunder technology, had also proved the thunder effect of drawing of lightning rod.Yet owing to the thunder and lightning cloud is to interact in the violent air motion to produce and have the gas electrified body of suitable volume, it has certain horizontal component, also has certain vertical field intensity simultaneously, and the motion irregular is fast changing.Adopt lightning rod to draw thunder and only can only cut moment part of horizontal electromagnetic component, can not effectively intercept and capture the vertical component of thunder and lightning thin clouds body electrified body.Fix owing to lightning rod again simultaneously, and the direction of attacking of thunder and lightning cloud is changeable indefinite.So lightning rod comprises that spininess all differs and effectively draws thunder surely, thereby reaches lightning-arrest relatively purpose.When especially lightning rod releases the lightening pulse electric energy huge in moment, around it, will produce very strong electromagnetic field, not have the safety zone at all.When testing in the electric wire of 1: hundreds of thousands volt by certain alternating current, just will produce very strong electromagnetic field around the lead, electric magnetisation, magnetic are given birth to electric again, and all possibility is sensed and get an electric shock, be magnetized and attract when its 1-2 rice is far away for people and animals.When lightning-arrest single needle draws thunder, huge pulse current wants conducting lightning arrester self hinged arm to be conducting to the earth neutralization, just in moment of this section " ideal wire that ground connection is good " conducting, will produce impayable huge electromagnetic field around it, this field intensity has substantially exceeded the limit that human body and general electric equipment can bear.So, lightning rod can only draw thunder and can not be effectively, lightning-arrest reliably.Experiment 2: plant the lightning-arrest single needle of the triangle tower of establishing three high 25 meters on about 6,000 square metres level land, the sea of fire that all produces about 15 meters radiuses when successively drawing thunder is smashed apart from lightning-arrest only about 3 meters far away tens of kilovolts of high voltage source transformers and the large-scale controller switching equipment of single needle.Only the television set, telephone set (external unsettled line is all arranged) etc. of 2 meters indoor storages far away are not all escaped misfortune with a lightning-arrest single needle wherein.The height of these desire protection equipment is all below 3 meters, and none is lucky.Put down in writing according to interrelated data: the television tower on the Red Square in Moscow, Russia though adopted lightning rod, is attacked more than 140 time by thunder and lightning still; New York, Pekinese's television tower have all adopted lightning rod, attacked by thunder and lightning tens of times, suffer heavy losses, and catch people's attention.In sum, lightning rod is exactly a lightning lead-in, does not have the safety zone around it, is when it draws thunder or all not have directly lightning-arrest electric effect when not drawing thunder.
The purpose of this utility model is that a kind of reliably grid-shielding lightning-shielding device of lightning-arrest electricity of various electric power, electric equipment that is fit to is provided for fear of the deficiency of above-mentioned existing lightning rod technology.
The purpose of this utility model can realize by following measure: a kind of grid-shielding lightning-shielding device, contain 6 (3-18) constitute approximate garden tubular perpendicular to ground metal garden bar, garden camber or interior drift angle are 120 °-180 ° grid cover metal cap, the main framing of metal cap with link to each other perpendicular to top on the metal garden bar on ground, the copper coin of termination 1-2 millimeters thick, about 2000 sq under the bar of metal garden, be embedded in underground 0.5-1 rice depths, add some charcoal foams around the copper coin, guarantee reliable ground.Around metal garden bar and garden camber cap on diameter about 5 millimeters bare copper wire at interval about 1 meter socket into the aperture plate shape and get final product.
The purpose of this utility model also can realize by following measure:
The grid-shielding lightning-shielding device, its interior diameter should be greater than pre-protection zone 3-4 rice, and promptly the protection zone is apart from grid cover 1.5-2 rice; Spatial altitude should be higher than pre-protection thing more than 1 meter in it; Can be according to the size of required lightning-arrest electric safety zone, just, form the grid cover arbitrarily.
The utility model has following advantage compared to existing technology:
1 the utility model can protect various electric power, telecommunications, television equipment to exempt from thunder and lightning and smash, and security reliability reaches 100% in the protection zone.
The poly-skin effect principle of 2 the utility model utilizations and shielding principle is isolated automatically, in and the thunder and lightning energy, reach the protection purpose.
3 the utility model height of devices are more much lower than the height of lightning rod, make that draw the possibility that thunder hit reduces significantly.
Concrete structure of the present utility model is provided by the following drawings:
1--metal garden type curtain bar
2--ground connection charcoal foam
The 3--copper earth plate
The 4--above-ground route
5--fence curtain line
6--garden camber metal gate guard cap
7--aperture plate cover cap skeleton
8--aperture plate cover metal curtain line
Operation principle of the present utility model is as follows:
Fig. 1 is the utility model theory structure schematic diagram; Fig. 2 is a top plan view,
With reference to Fig. 1; 2 when thunder and lightning thin clouds body electrified body from pre-protection zone around any direction when attacking; metal garden type curtain bar (1) will intercept the poly-skin of its horizontal component; shielding and the earth neutralization; the fence curtain line (3) of the level connection on the metal garden type curtain bar (1) will intercept the vertical component of its electrified body simultaneously; poly-skin, shielding neutralize with the earth: when thunder and lightning thin clouds body electrified body when top, pre-protection zone attacks; garden camber metal grid mesh cap (6) will intercept the level and the vertical component of its electrified body, poly-skin, shielding and the earth neutralization.Make thunder and lightning thin clouds body electrified body to smash thereby the electric equipment in the pre-protection zone of very reliable assurance exempts from thunder and lightning near the electric equipment in the pre-protection zone.
