On the basis of above-mentioned technical proposal, following attached technical scheme is further included：
The arrester, downlead, building grounded screen, screen layer use conductive material, the resistance to dielectric that punctures to adopt
With with the material compared with high breakdown field strength and good insulation properties.
The arrester, downlead, screen layer use stainless steel or copper, the lower end connection of the lower end and screen layer of downlead
In the grounded screen of building, building grounded screen is resistance to puncture insulation Jie using reinforced concrete structure and with smaller earth resistance
Matter includes two-layer, and internal layer uses one layer of epoxy resin, and it is concrete that outer layer is then poured.
The cross sectional shape of the screen layer is circular for semicircle or a quarter, under arrester and the drawing being connected with arrester
Line is located at the center of circle of screen layer.
The arrester is with downlead, downlead and building grounded screen, screen layer and building grounded screen by welding
Good electrical through-current capability is kept etc. mode.
The downlead lower end keeps electrically conducting and equipotential with screen layer lower end.
The arrester has cuspidated round steel using top, and downlead uses the heart yearn of shielded cable, around downlead
Screen layer using below aperture 1m welded steel fabric.
It is arranged on the edge of building etc. or corner, and the screen layer center of circle outwards, and place building side
Sufficiently large spacing is kept with other buildings.
The utility model advantage is：
The utility model is easily achieved, and lightning rod and its downlead are carried out to shield the electricity that can weaken when lightning current is released
Magnetic field impulse is radiated, so that it is sensitive electronic equipment to protect interior of building.Additionally, present apparatus installation site in building side or
Person corner, can increase the space of interior of building low electromagnetic, by the reflection of Semi-shielded layer by Electro-Magnetic pulse Shielding
Beyond building.Compared with conventional full-shield formula shielding lightning arrester, the utility model can save the original of more than half
Material cost, installation site is more flexible, with broader practice prospect, can be widely applied to building, warehouse, oil depot
Deng being particularly well-suited to the isolated Architectural Equipment of comparing.

Specific embodiment
Embodiment：As Figure 1-3, the utility model provides a kind of the first reality of Semi-shielded formula lightning rod screening arrangement
Example is applied, it includes：Downlead 2 that arrester 1 is connected with arrester 1, the screen layer 5 shielded to downlead 2, positioned at drawing
The resistance to building for puncturing dielectric 4 and being connected with the lower end of downlead 2 and the lower end of screen layer 5 between offline 2 and screen layer 5
Thing grounded screen 3.Arrester 1, downlead 2, screen layer 5 are made it have good electric using the metal material such as stainless steel or copper
Ducting capacity.Downlead 2 and the lower end of screen layer 5 are connected to building grounded screen 3, and building grounded screen 3 uses reinforced concrete knot
Structure and with smaller earth resistance, the resistance to dielectric 4 that punctures includes two-layer, and internal layer uses one layer of very thin epoxy resin to resist
Electrical breakdown, outer layer casting concrete is insulating.The section of screen layer 5 is semicircle, under arrester 1 and the drawing being connected with arrester 1
Line 2 is located at the center of circle of semicircle screen layer 5.Arrester 1 and downlead 2, downlead 2 and building grounded screen 3, screen layer 5 with
