The utility model discloses simple structure increases thunder and lightning electromagnetic pulse safeguard function on the basis of conventional franklin lightning rod, reduce near the thunder and lightning electromagnetic pulse intensity in lightning arrester to reduce the risk that near its electron electric installation was hurtd by thunder and lightning electromagnetic pulse, but wide application in the lightning protection of various facilities and equipment such as building, removal equipment, oil depot.
Description
Technical field
The utility model relates to a kind of direct lightning strike shielding lightning arrester.
Background technology
Thunder and lightning is large public hazards of current era, particularly forms very large threat, every year all because thunder calamity causes heavy losses to the safety in the highest priority regions such as oil depot, space launching center, airport, scenic spot.According to statistics, the economic loss that annual China causes because of thunderbolt reaches several hundred million unit.Franklin lightning rod is most popular thunderstorm electricity protective device, in direct lightning strike protection, serve irreplaceable effect.But Franklin lightning rod is while playing direct lightning strike protective action, add install terminal location by lightning strike probability, thus make the electric facility near lightning rod easily suffer Lightning Electromagnetic Pulse and cause and injure.
Utility model content
The purpose of this utility model there is provided a kind of direct lightning strike shielding lightning arrester, reduces the Lightning Electromagnetic Pulse intensity near lightning arrester.
For reaching the purpose of this utility model, the utility model adopts following technical scheme: a kind of direct lightning strike shielding lightning arrester, and it comprises: the screen use the arrester of Franklin principle, the downlead be connected with arrester, the earth electrode be connected with downlead, shielding to downlead, the insulation filler between downlead with screen and the shielding layer grounding body be connected with screen.
On the basis of technique scheme, comprise following attached technical scheme further:
Described arrester, downlead, earth electrode, screen and shielding layer grounding body all adopt the material with excellent conductive performance, and adopt welding, screw thread or securing member to be connected between arrester with downlead.
Described material is copper, steel, iron.
Described screen is placed in insulation filler completely, and the top of insulation filler is provided with insulative water-proof cover.
Described earth electrode and shielding layer grounding body keep gap.
Described downlead, screen, insulation filler are segmented design, and screen adopts reed to compress connection between respectively saving.
Described downlead is middle reinforcing bar, screen be around middle steel-bar arrangement multiple reinforcing bar and be wound around the wire netting of these reinforcing bars, and insulation filler is the concrete of building.
The utility model advantage is:
The utility model structure is simple, the basis of conventional Franklin lightning rod increases Lightning Electromagnetic Pulse safeguard function, reduce the Lightning Electromagnetic Pulse intensity near lightning arrester, thus reduce the risk that near it, electric facility is injured by Lightning Electromagnetic Pulse, the lightning protection of the various facilities and equipment such as building, Mobile Equipment, oil depot can be widely used in.

Embodiment
Embodiment: as shown in Figure 1-2, the utility model provides a kind of direct lightning strike to shield the specific embodiment of lightning arrester, and it comprises: the screen 4 use the arrester 1 of Franklin principle, the downlead 2 be connected with arrester 1, the earth electrode 3 be connected with downlead 2, shielding to downlead 2, the insulation filler 5 between downlead 2 with screen 4 and the shielding layer grounding body 6 be connected with screen 4.
Arrester 1, downlead 2, earth electrode 3, screen 4 and shielding layer grounding body 6 all adopt the material with excellent conductive performance to make, as the material such as copper, steel, size should meet the lightning current through-current capability requirement of design, can adopt between arrester 1 with downlead 2 weld, screw thread or securing member be connected, and ensures to have good electrical connection and through-current capability.Earth electrode 3 and shielding layer grounding body 6 can adopt general lightning-proof grounding body (as copper covered steel earth rod), adopt to weld or securing member is connected between downlead 2 with earth electrode 3, ensure to have good electrical connection and through-current capability.Good insulation property should be had between screen 4 and downlead 2, to ensure can not puncture when lightning current is released, insulation filler 5 is adopted to insulate between screen 4 and downlead 2, and insulation filler 5 has good water resistance, screen 4 top and outside are placed in insulation filler 5 completely, to prevent rainwater conducting screen 4 and downlead 2.The top of insulation filler 5 is provided with insulative water-proof cover 8, forms the electrically conducting between arrester 1 and ground when avoiding rainy outside insulation filler 5 because of rainwater.Screen 4 has independent shielding layer grounding body 6, has certain distance between shielding layer grounding body 6 and earth electrode 3.
As shown in Figure 3-4, when adopting segmented design, downlead 2 is divided into more piece, during merogenesis, downlead 2, screen 4, insulation filler 5 merogenesis together, junction, downlead 2 can adopt and be threaded, and reed 7 can be adopted to compress connect between each joint of screen 4.
As shown in Figure 5, the present embodiment is applied to building when taking shelter from the thunder, utilize the reinforcing bar of support column as downlead and screen, it comprise use the arrester 10 of Franklin principle, the downlead 20 be connected with arrester 10, the earth electrode 30 be connected with downlead 20, screen 40 that downlead 20 is shielded, insulation filler 50 between downlead 20 with screen 40 and the shielding layer grounding body 60 that is connected with screen 40.Namely in the middle of setting one, reinforcing bar is as downlead 20, and the outside reinforcing bar of surrounding adds the webbed screen 40 of wire netting shape, and concrete is as insulation filler 50.
