Abstract
The utility model relates to a lightning-proof grounding net of a nuclear power station, belonging to the technical field of corona discharge devices. The lightning-proof grounding net comprises round steels, wherein the round steels are arranged at the outer side of a building and is grounded; one group of longitudinally-arranged round steels and another group of horizontally-arranged round steels are crossed to form a steel net; the steel net forms a steel cage enveloping the outer side of the building; and the steel cage is provided with a group of spaced fixed-connecting points with structural steel bars on the building. The lightning-proof grounding net has the advantages of high protection capability and good shielding effect.
Description
Technical field
The utility model relates to a kind of nuclear power station lightning protection grounding network, belongs to the corona discharge assembly technical field.
Background technology
At present, building lightning protection ground connection is by the energy of its top lightning rod according to point discharge principle absorption thunder and lightning, and in the energy importing the earth of earthing conductor with thunder and lightning by its connection.Lightning rod generally is located at the top of building.The building that nuclear power station requires as high security protection, its protection to thunder and lightning need to be accomplished how redundant perfectly safe to realize, the lightning rod that install on traditional top only can be realized the lightning protection at top, contingent middle part and bottom thunderbolt there is not protective capacities, the electromagnetic interference that may cause thunder and lightning does not possess screening ability yet, can't satisfy the needs of nuclear power station lighting protection.
The utility model content
The technical problems to be solved in the utility model is to propose a kind of nuclear power station lightning protection grounding network that possesses better lightning protection and screening ability.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of nuclear power station lightning protection grounding network, comprise the round steel of being located at building outside ground connection, one group of round steel longitudinal arrangement and another transversely arranged group intersect to form steel mesh, steel mesh consists of envelope in the steel cage in the building outside, and steel cage and architectural structure reinforcing bars have the affixed point at one group of interval.
Preferably, the spacing of one group of affixed point is 1m.
Preferably, round steel is the galvanizing by dipping round steel of diameter 10mm.
Preferably, build and be factory building, the mesh spacing of steel cage is not more than 5m*5m.
Preferably, build and be gallery, the mesh spacing of steel cage is not more than 1m*10m.
Preferably, build and be electric, electronic equipment room, the mesh spacing of steel cage is not more than 2m*2m.
Lightning protection grounding network of the present utility model can be chosen the building that rational mesh spacing is protected obstructed degree of protection owing to adopted network structure, and the beneficial effect that has is:
1, the degree of protection to thunder and lightning is high, can not only protect thunder and lightning hitting and destroying, all right contingent thunder disaster of disposition all directions building top.
2, preferred round steel diameter reaches the different mesh spacings of taking for different building types, can reduce to greatest extent the consumption of round steel when realizing best lightning protection effect, has saved cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment
The lightning protection grounding network of present embodiment as shown in Figure 1, the round steel that comprises ground connection on the outer wall of being located at building, the galvanizing by dipping round steel of preferred diameter 10mm, one group of round steel and another transversely arranged group round steel of longitudinal arrangement have intersected to form steel mesh, steel mesh closely is laid in the outside of architectural structure reinforcing bars, the total reinforcing bar forms a cube along the profile of building, and the steel mesh that lays has thereon also just formed a cubical steel cage, every the spacing of 1m steel cage and structure reinforcing bars is welded.
When lightning protection grounding network was located at the structure reinforcing bars outside of factory building, the mesh spacing of steel cage was not more than 5m*5m.
When lightning protection grounding network was located at the structure reinforcing bars outside of gallery, the mesh spacing of steel cage was not more than 1m*10m.
When lightning protection grounding network was located at the structure reinforcing bars outside in electric, electronic equipment room, the mesh spacing of steel cage was not more than 2m*2m.
According to faraday's cylinder mould shielding principle; the nuclear power station lightning protection grounding network of present embodiment can carry out effective lightning protection to factory building; can collect, guide and be dispersed in the earth by the most direct loop transient current that produces that will be struck by lightning; consisted of the equipotential environment in the Nuclear Power Station Factory Building structure, for Nuclear Power Station Factory Building provides enough effectively shielding.
The above only is preferred embodiment of the present utility model, as long as adopt the technical solution of the utility model, perhaps modification or the equivalent variations made based on conventional means on it of those skilled in the art all drops in the protection range of the utility model requirement.
