Description
Technical field
The utility model relates to the electric power facility technical field, is a kind of ground network specifically with the corrosion-resistant ion earthing rod of filling.
Background technology
For ensureing the safety of electric power system power transmission and distribution; transmission line and electric equipment all must be installed earth electrode; earth electrode comprises again vertically buries earth electrode and horizontally embedded ground network underground; these grounding apparatuss are the indispensable facilities that are used for working earthing, lightning protection, protective earthing; also be the important step of guaranteeing the person, equipment, system safety, it plays a part earial drainage and all presses at aspects such as anti-thunder and lightning, static and fault currents.
Along with the continuous increase of electric power system capacity, the requirement of ground network safe operation is more and more stricter, and is also just high more to the thermal stability requirement of earth electrode, in China, owing to resource, economic dispatch reason, earth electrode is embedded in underground, can't directly change its ground connection effect.In case after earth electrode put into operation for a long time, problem with grounding will come out.
Provide in for 03205158.1 utility application text a kind of name to be called the technical scheme of " ion earthing rod " in the patent No., it comprises the barred body of a hollow circuit cylinder body structure, the two ends of barred body are separately installed with cap and following cap, be filled with in the barred body and can absorb the reactive electro ionic compound that water in air is divided, be evenly equipped with spiracle on the barred body body wall, be provided with the ground wire connector on last cap, the ground wire connector is connected with an earth connection that the external equipment that is grounded is extended out.Deliquescent effect by filler in the barred body in the work effectively is discharged into the reactive electro ion in the soil and soil and airborne water function, promotes the outside slowly-releasing of conductor to fall resistance and keep the resistance long-term stability; And the colloid pellucidity progressively is combined in the prolongation in time of the compound of conductor inside, can by the spiracle on the barred body wall constantly towards periphery environment discharge a large amount of conductive ions.
Application number is 200910182317.0 patent of invention anti-corrosion type energy-storage ionic earthing array, relate to a kind of anti-corrosion type energy-storage ionic earthing array, feature is: adopt the stainless steel ball conductor to be provided with the ion barred body and the screen that catchments, strengthened the contact area with soil, reduced earth resistance; Be equipped with the level gauging device, satisfied solion Level Detection in the spheroid; Setting up the screen that catchments and to collect in the soil hydrone in spheroid; Can the moment energy storage absorb the thunderbolt pulse current, the lightning surge electromagnetic pulse is reduced at double, better meet the lightning protection requirement; And can be grounded the anticorrosion energy storage slowly-releasing and the low function of earth resistance of the utmost point.
Removed above-mentioned patent, existing ion grounding electrode product also has three problems in actual applications: the etching problem of first earth electrode.Existing ion grounding electrode is metallic article, and main body pipe inside is electrolyte, and the material that produces in the process of its reaction can quicken corrosion of metal; The 2nd, the consumption problem of resistance-lowering material.Because the degree of the reduction of soil resistivity and useful life and filler dosage are proportional substantially, along with prolong service time, resistance-lowering material does not arrhea mistake, causes it to fall the resistance ability and weakens; It three is that to fall the resistance process be a passive process.Can soil resistivity be effectively reduced, not only relevant with the character of sustained release agent, and it is closely related with the moisture in the soil, because absorbing moisture, this earth rod comes down to a passive process, when moisture in the soil is very low, its ability that absorbs moisture must be subjected to limiting to greatly, therefore might cause the reduction degree of soil resistivity can not reach designing requirement.
Summary of the invention
The purpose of this utility model is the problem that prior art exists is solved, so provide a kind of easy to use, resistance and obvious results ground network are fallen lastingly with the corrosion-resistant ion earthing rod of filling.
The technical solution of the utility model is achieved in that
Has a corrosion-resistant non-metallic pipe of hollow, be equipped with and composite high-molecular resistance-lowering material and the carbon-point that is connected with ground network inside, the corrosion-resistant non-metallic pipe of hollow top is provided with filling cap, has the permeability hole for the conductive ion turnover in the middle and lower part of the corrosion-resistant non-metallic pipe of hollow.
The corrosion-resistant non-metallic pipe material of hollow is one of phenolic resins, neoprene, polyvinyl chloride, butadiene-styrene rubber, polyamide, melamine, polyethylene, polypropylene, a polytetrafluoroethylene material.
The composite high-molecular resistance-lowering material is filled repeatedly.
Compared with prior art, the advantage of the utility model technology is: 1. the corrosion resistance of earth electrode is strong, and prolong useful life; 2. the use of earth electrode is not subjected to the influence of local edaphic condition, can guarantee to be issued to the design objective requirement in any high resistant soil environment; 3. this ion grounding electrode compound resistance-lowering material of filling can be filled repeatedly, useful life in theory can be identical with transformer station and render a service lasting.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Number in the figure 1 is the corrosion-resistant non-metallic pipe of hollow, and 2 is the composite high-molecular resistance-lowering material, and 3 is filling cap, and 4 is carbon-point, and 5 is permeability hole.
Embodiment
Below with reference to drawings and Examples content of the present utility model is described further, but actual fabrication structure of the present utility model is not limited in following embodiment.
Referring to accompanying drawing, ground network described in the utility model comprises a corrosion-resistant non-metallic pipe of hollow (1) with the corrosion-resistant ion earthing rod of filling, be equipped with and composite high-molecular resistance-lowering material (2) and the carbon-point that is connected with ground network (4) inside, and the corrosion-resistant non-metallic pipe of hollow (1) top can have the permeability hole (5) that passes in and out for conductive ion for the filling cap (3) of filling resistance-lowering material in the middle and lower part of the corrosion-resistant non-metallic pipe of hollow (1).During concrete the application, can partly be embedded in the corrosion-resistant non-metallic pipe of hollow (1) in the soil, and ground connection carbon-point (4) linked to each other with ground network by lead, moisture interacts in composite high-molecular resistance-lowering material (2) and soil, form conductive ion, slowly be discharged in the soil the electrolyte dissolution in the resistance-lowering material and by the permeability hole infiltration equably.Along with the continuous infiltration of electrolyte ion, but the conductive ion quantity that enters soil constantly increase, play the effect that reduces soil resistivity.
When dry so that with compound resistance-lowering material in water-keeping material be not enough to effectively provide moisture, when reducing earth resistance, can open filling cap, suitably pour into moisture to earth electrode; When the prolongation along with service time, compound resistance-lowering material consumption can replenish compound resistance-lowering material and moisture at any time to earth electrode more for a long time, is in the resistance state that falls of long-acting efficient to guarantee it.
