Technical field
The present invention relates to a kind of earthing device, particularly relate to a kind of environment protective leakage-resisting humidity-preserving type earthing device and construction method, be applicable to large-scale substation and resistance reducing agent or graphite ground connection carbon-point must be used to reach in the construction reducing grounded screen electric resistance value.In addition, the earthing device being also applicable to the communication apparatus such as mobile communication tower, television tower, microwave tower, radio station, radar station, railway needs to use in the construction of resistance reducing agent, belongs to electric power system electrical equipment grounding net construction field.
Background technology
Grounding net of transformer substation is to guarantee power equipment safety stable operation and ensure that running patrol officer plays safely very important effect, and the main electrical parameters of grounding net of transformer substation is earth resistance, contact potential difference and step potential difference.A lot of transformer station is had to plough and mountain forest in order to avoid destroying, often all build on discarded riverbed, with on the ditch of sandstone backfill and on half way up the mountain, because geological state is bad, its soil resistivity is general all very high, grounded screen electric resistance is finally caused to be above standard requirement, in order to reduce soil resistivity, inorganic resistance reducing agent or organic resistance reducing agent in ground network construction, is generally all used to reach the object reducing soil resistivity in transformer station.
Find by detecting the grounding net of transformer substation of 60 66kV and above and lightning rod, newly-built or transformation grounding net of transformer substation or lightning rod test number very little, generally equal can meet " code " requires or design standard, but run 1 year or again test after the longer time, find that test data has the trend of obviously increase than front once surveyed data, have the ground network of 21 transformer stations or lightning rod defective.By using resistance reducing agent or graphite ground connection carbon-point earthing device to excavate inspection to 13 places, the resistance reducing agent thrown in of finding to construct originally reaches 30% ~ 50% along with rain water runoff, the graphite ground connection carbon-point used is suspended in sandstone, surrounding soil resistivity increases, soil property dries up, and has crops or weeds around the outer earthing device leading to use resistance reducing agent in cropland of part to occur withered phenomenon.As everyone knows, all resistance reducing agents are generally all made up of inorganic chemistry or organic chemical, although some manufacturer can claim that the resistance reducing agent produced can not pollute the Nature, but we know, the pH value of the major part soil water is 6 ~ 6.75, namely aobvious neutral, also have pH value be 7.5 ~ 9.5 saline-alkali soil, also have pH value to be the acid soil of 3 ~ 6.And the use of resistance reducing agent makes resistivity around soil reduce by increasing pH value (9 ~ 12), finally reach the object reducing grounded screen electric resistance.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of environment protective leakage-resisting humidity-preserving type earthing device, solve in prior art the problem using the place of resistance reducing agent or graphite ground connection carbon-point easily to cause environmental pollution, and resistance reducing agent can be prevented to run off.
Another object of the present invention is to the construction method providing a kind of environment protective leakage-resisting humidity-preserving type earthing device.
Technical scheme of the present invention is as follows:
The outer surface of container arranges hot galvanized layer, and container is provided with electrical connection soldering tip.
Described container is truncated cone-shaped metal bucket or rectangle metal trough.
Construction method of the present invention comprises the steps;
According to vertical-type or the requirement of horizontal type construction method, after original sandstone or back fill course dig a truncated cone-shaped or rectangle dell, a hot galvanizing truncated cone-shaped metal bucket or hot galvanizing rectangle metal trough are put into the bottom in hole, then the resistance reducing agent of use or graphite ground connection carbon-point are put into the bottom of metal bucket or metal trough, truncated cone-shaped heatable adobe sleeping platform put into by metal bucket, and metal trough puts into rectangle trench, when using resistance reducing agent or graphite ground connection carbon-point, bottom connecting line on metal bucket or metal trough being welded on graphite ground connection carbon-point is drawn on galvanized sheet, graphite ground connection carbon-point top lead-out wire and major network zinc-coated flat steel sheet weld together, then the resistance reducing agent be stirred in advance or graphite ground connection carbon-point are poured in metal bucket or metal trough, the number that resistance reducing agent is put into should lower than metal bucket or 30 millimeters, metal trough upper end, if resistance reducing agent uses time different from graphite ground connection carbon-point, and when being only used alone graphite ground connection carbon-point, can the mixture of the moistening fine earth be stirred in advance and iron ore be inserted in metal bucket or metal trough, how much insert should lower than metal bucket or 30 millimeters, metal trough upper end, then the yellow clay compacting of 100 millimeters thick is covered in the above, backfill fine earth compacting is subsequently also concordant with peripheral ground.
Advantageous effect of the present invention is as follows:
The present invention is applicable to all use resistance reducing agent or graphite ground connection carbon-points of needing and reaches in the construction reducing ground network main electrical parameters, this device can reduce resistance reducing agent and to leak the pollution range caused the Nature, can reach again the effect such as moisturizing around earth electrode, anti-resistance reducing agent loss.
