Cathode protection electrolyte is filled in the grounding pipes and seeps into soil through the seepage holes (6) to keep the soil wet constantly and increase the free ions in the soil. The device has the advantages of obviously reducing grounding resistance and effectively ensuring the reliability of a grounding network. Particularly in areas and seasons of high soil resistance and he device has obvious effects.
Description
Technical field
The present invention relates to the special arrangement that a kind of lightning protection and electrical grounding engineering are used, specifically, but is a kind of monitoring low-resistance module grounding device.
Background technology
At present, all lightning protection and electrical grounding engineerings such as power plant, transformer station, control machine room adopt zinc-plated round steel, band steel, angle steel etc. as horizontal grounding and vertical grounding electrode more, imbed in the following soil of underground 0.8-3.0m.And in high soil resistivity and arid area, owing to lack the additional conductive effect of free ion in the soil, the earth resistance of grounding system is difficult to reach requirement, usually adopt soil removal and replacement, add chemistry or physics resistance reducing agent, bore deep-well and bury vertical electrode underground, extend measures such as ground network area, to reduce earth resistance.These method workloads are big, waste time and energy, and difficulty of construction is big, the cost height, and also because soil and resistance reducing agent have corrosivity, and earth electrode very easily is corroded, and makes the ground network decreased performance, shorten useful life.
Summary of the invention
Technical problem to be solved by this invention is: but by a kind of monitoring low-resistance module grounding device is provided, not only can significantly reduce earth resistance, and can carry out monitoring automatically to earth resistance.The grounding system long service life, construction is simple, and engineering cost is low.To overcome the defective of above-mentioned prior art.
In order to solve these technical problems, the present invention has adopted following technical scheme.
But a kind of monitoring low-resistance module grounding device comprises the earth electrode that is connected with down conductor, it is characterized in that: described earth electrode comprises some the horizontal grounding pipes and the some vertical ground pipes that are communicated with respectively with the horizontal grounding pipe that are communicated with successively; All offer some liquid-leadage holes on horizontal grounding pipe and the vertical ground pipe; Also comprise the reservoir that is used to contain liquid, it is communicated with above-mentioned ground pipe by liquid injection pipe.
Also comprise watch-dog, it is by detection line and a plurality of earth resistance points that are connected earth electrode.
What pour in reservoir and the ground pipe is cathodic protection electrolyte.
Good effect of the present invention is:
The first, underground hollow tube ground network and liquid injection pipe and on the ground reservoir link to each other.Annotate cathodic protection electrolyte in the ground pipe, infiltrate soil, make soil keep moisture state for a long time, increased the free ion in the soil by permeability hole.Significantly reduce earth resistance, effectively guaranteed the reliability of ground network.Especially in high soil resistivity and arid area and season, effect is particularly remarkable.
Simultaneously earth electrode is played a protective role, effectively the protective earthing body increases the service life.
The second, the hollow tube grounding system is equipped with the earth resistance automatic monitoring controller, sets the earth resistance definite value on request.Select a plurality of earth resistance points, the earth resistance numerical value of surveying feeds back to watch-dog automatically, and when resistance during greater than set point, watch-dog is reported to the police, and can realize replenishing automatically electrolyte.
Three, this grounding system is imbedded between the underground 0.8-3.0m, and construction volume is few, and simple installation can effectively reduce cost.

Further specify the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1,2, equipment supporter 7 connects earth electrode by down conductor 8, and described earth electrode comprises some the horizontal grounding pipes 4 and the some vertical ground pipes 5 that are communicated with respectively with horizontal grounding pipe 4 that are communicated with successively.Above-mentioned ground pipe all adopts the metal tube of high conductivity or multiple tube to make electric conductor, all offers some liquid-leadage holes 6 on horizontal grounding pipe 4 and the vertical ground pipe 5.Use threeway 1, four-way, elbow 3, the pipe fittings such as straight-through 2 of identical material,, be arbitrarily made with various forms of hollow tube ground networks, implant the underground 0.8-3.0m degree of depth according to different requirements.
The reservoir 10 that is used to contain liquid is communicated with above-mentioned ground pipe by liquid injection pipe 9.What pour in reservoir 10 and the ground pipe is cathodic protection electrolyte, such as copper-bath.
Watch-dog 11 is by detection line 12 and a plurality of earth resistance points that are connected earth electrode.
The construction and installation step is as follows:
One, ditching 0.8-1.2m is dark, the auxilliary horizontal grounding body of establishing.
Two, press certain distance boring, bury the vertical junction terrain underground.
Three, horizontal grounding body and vertical junction ground body and function pipe fitting transition, the scene is welded or is threaded.
Four, earthing, compacting, fluid injection.
