Abstract
The invention discloses a well group grounding net which comprises seven grounding electrodes and a grounding lead-up wire, wherein one of the grounding electrodes is arranged in the middle; the other six grounding electrodes are positioned around the grounding electrode; and the six surrounding grounding electrodes are not directly connected with one another, and are connected with the middle grounding electrode, respectively. The grounding net has the advantages of high security, high land utilization rate, convenience in maintenance and replacement and the like.
Description
Technical field
The present invention relates to a kind of gang of wells ground network.
Background technology
The ground network of locating for power plant, electric substation etc. both at home and abroad all adopts grid square or the pane ground network of decussation at present, the ground network of these shapes is because horizontal arrangement, not only waste a large amount of earthing materials, and engineering is huge, the corrosion back is changed very difficult.Moreover, because that present earth mat is buried underground is more shallow, also brought an earth resistance ground step voltage more high difficult problem high and that form thus thus.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of gang of wells ground network in order to address the above problem, and it has safe, land use rate height, be convenient to advantage such as maintain and replace.
To achieve these goals, the present invention adopts following technical scheme:
A kind of gang of wells ground network comprises that seven earth electrodes and ground connection drawing reach the standard grade; In the middle of described seven earth electrodes, one of them earth electrode were located at, all the other six earth electrodes were positioned at around it; Described directly connection between six earth electrodes on every side, and be connected with the described earth electrode that is positioned at the centre respectively.
Connection between the described earth electrode is to interconnect by conductor under thin solum.
Described six earth electrodes around being positioned at are evenly distributed on around the earth electrode in the middle of described being positioned at: any two around earth electrode and the earth electrode in the centre between be wired to 60 °; All equate to the distance between the earth electrode in the centre at earth electrode on every side.
Described earth electrode comprises well body, earth electrode and auxiliary packing material, and earth electrode is located in the well body, and middle the employing assists packing material to fill.
Described ground connection drawing reaches the standard grade and draws from being positioned at middle earth electrode.
Beneficial effect of the present invention:
1. introducing is underground rapidly with big impact earth current for the deep-wall type earth electrode, has increased ground integrity;
2. the gang of wells shape stereochemical structure on the space farthest increases ground connection density, has increased land use efficient;
3. in the higher area of specific soil conductivities such as mountain area, desert, high density gang of wells shape ground network is because having the maximum density of arranging, floor space is less, is conducive to select a best earth point to bury ground network underground;
4. after using in many years, each earth electrode can check one by one, safeguards, change, and need not have a power failure, stop production;
5. the direct-to-ground capacitance of this ground network is little, when being used for the neutral ground net then neutral point coupling effect is little over the ground, more be conducive to power grid security.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of single earth electrode.
Wherein, 1. well body; 2. assist packing material; 3. earth electrode; 4. earth electrode; 5. ground connection drawing reaches the standard grade; 6. conductor.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, 2, a kind of gang of wells ground network comprises that seven earth electrodes 4 and ground connection drawing reach the standard grade 5; In the middle of described seven earth electrodes 4, one of them earth electrode 4 were located at, all the other six earth electrodes 4 were positioned at around it; Described directly connection between six earth electrodes 4 on every side, and be connected with the described earth electrode 4 that is positioned at the centre respectively.
Connection between the described earth electrode 4 is to interconnect by conductor 6 under thin solum.
Described six earth electrodes 4 around being positioned at are evenly distributed on around the earth electrode 4 in the middle of described being positioned at: any two around earth electrode 4 and the earth electrode 4 in the centre between be wired to 60 °; All equate to the distance between the earth electrode 4 in the centre at earth electrode on every side 4.
Described earth electrode 4 comprises well body 1, earth electrode 3 and auxiliary packing material 2, and earth electrode 3 is located in the well body 1, and middle the employing assists packing material 2 to fill.
Described, ground connection drawing 5 the earth electrodes 4 in the middle of be positioned at of reaching the standard grade are drawn.
When building this gang of wells ground network, at first select the lower place of electric resistance of soil resistivity, select rational spacing to beat deep-well.Again will the earth electrode 4 of centre with around earth electrode 4 between be connected with conductor 6, draw ground network at the earth electrode 4 that is positioned at the centre and draw and reach the standard grade 5.At last with the ground network landfill.
It is the above corrosion resisting alloy steel pipe of 25mm that each earth electrode 4 has all adopted diameter, is graphite compositing conducting material in the steel pipe.The degree of depth of each well body 1 is 1.5~5 meters, can be divided into 2~20 meters with distance between other earth electrodes 4 according to different electric pressures at the earth electrode 4 of centre, and it is the above common rib steel of 25mm that conductor 6 is selected diameter for use.When building earth electrode 4, use the above trepan drilling well of diameter 20cm earlier, after earth electrode 3 is put down, fill composite materials such as graphite and bentonite around as auxiliary packing material 2, the sealing of pouring water at last.
Though above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not construed as limiting the scope of the present invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
