Grounding net of transformer substation is patrolled and examined personal security with the assurance operation and is played important effect guaranteeing power equipment safety stable operation, and the main electrical parameters of grounding net of transformer substation is earth resistance, contact potential difference and the potential difference that strides.There are a lot of transformer stations to plough and mountain forest for fear of destroying; Often all build on the discarded riverbed, with on the ditch of sandstone backfill and on the half way up the mountain; Because geological state is bad, its soil resistivity is generally all very high, finally causes the grounded screen electric resistance requirement that is above standard; In order to reduce soil resistivity, generally all use inorganic resistance reducing agent or organic resistance reducing agent to reach the purpose that reduces soil resistivity in the transformer station in the ground network construction.
Grounding net of transformer substation and lightning rod through to 60 66kV and above electric pressure detect discovery; Grounding net of transformer substation or lightning rod test number newly-built or that transform are very little; General equal can meet " rules " require or design standard; But moved 1 year or test once more after longer time, find that test data has the trend of obvious increase than the preceding once data of surveying, and has the ground network of 21 transformer stations or lightning rod defective.Through using resistance reducing agent or graphite ground connection carbon-point earthing device to excavate inspection to 13 places; Find that the resistance reducing agent that construction is originally thrown in reaches 30%～50% along with rainwater runs off; The graphite ground connection carbon-point that uses is suspended in the sandstone; Surrounding soil resistivity increases, soil property is withered, has that part is outer to lead to around the earthing device that uses resistance reducing agent in the cropland crops or withered phenomenon appears in weeds.As everyone knows; All resistance reducing agents generally all are made up of inorganic chemistry or organic chemistry material, can not pollute the Nature although the resistance reducing agent of producing can be claimed by some manufacturer, and we know; The pH value of most of soil water is 6～6.75; Promptly show neutral, it is 7.5～9.5 saline-alkali soil that pH value is also arranged, and also having pH value is 3～6 acid soil.And the use of resistance reducing agent is to make soil resistivity reduction on every side through increasing pH value (9～12), finally reaches the purpose that reduces grounded screen electric resistance.
Summary of the invention
The utility model is to the problem that exists in the above-mentioned prior art; A kind of environmental protection leakproof humidity-preserving type earthing device is provided; Solved and used the place of resistance reducing agent or graphite ground connection carbon-point to be prone to cause environmental pollution problems in the prior art, and can prevent that resistance reducing agent runs off.
The technical scheme of the utility model is following:
The outer surface of container is provided with hot galvanized layer, and container is provided with and is electrically connected soldering tip.
Described container is truncated cone-shaped metal bucket or rectangle metal trough.
The utility model has the advantages of as follows:
The utility model is applicable to that all need use resistance reducing agent or graphite ground connection carbon-point to reach and reduce in the construction of ground network main electrical parameters; This device can dwindle the pollution range that resistance reducing agent leaks the Nature is caused, and can reach effects such as earth electrode is preserved moisture, anti-resistance reducing agent loss again on every side.

Embodiment
Combine specific embodiment to describe the utility model in detail with reference to the accompanying drawings.
Embodiment
Shown in Fig. 1-4, environmental protection leakproof humidity-preserving type earthing device is according to the desert method principle that plants tree seedlings.In vertical earthing device is used; Make the hot galvanizing truncated cone-shaped metal bucket that a charged gas connects soldering tip; On the metal bucket diameter 600 millimeters, following 300 millimeters, high 500 millimeters, thick 0.5 millimeter; This earthing device is put into the truncated cone-shaped hole that needs use resistance reducing agent or graphite ground connection carbon-point, and construction gets final product as requested again.In the horizontal grounding device is used; Make the hot galvanizing rectangle metal trough that a charged gas connects soldering tip; High 300 millimeters, wide 300 millimeters, thick 0.5 millimeter of metal trough; Length can be decided according to the graphite ground connection carbon-point quantity of using, and this device is put into the rectangle hole that needs use resistance reducing agent or graphite ground connection carbon-point, and construction all can as requested.
During the utility model is applicable to that all earth resistances that need use resistance reducing agent 6 or graphite ground connection carbon-point 3 to reach reduction grounding net of transformer substation or lightning rod are constructed.Particularly be applicable to build on the backfill soil bed thickness, the earthing device of the communication apparatus such as transformer station, mobile communication tower, microwave tower, radar station, railway on around on the riverbed, on the mountain and the mountain need use in the construction of resistance reducing agent 6 or graphite ground connection carbon-point 3.
