Description
Technical field
The utility model relates to the electric power facility technical field, is a kind of with refilling type high-efficiency environment friendly ion grounding electrode specifically.
Background technology
Grounding net of transformer substation is the indispensable facility that is used for working earthing, lightning protection, protective earthing, also is the important step of guaranteeing the person, equipment, system safety, and it plays a part earial drainage and all presses at aspects such as anti-thunder and lightning, static and fault currents.When earth resistance is excessive, short circuit current will cause the ground network current potential to raise owing to can't fully spread in soil; make the metal shell band high voltage of grounding apparatus and jeopardize personal safety and puncture the second protection device and insulate; even damage equipment, the expansion accident, it is stable to destroy network system.The excessive phenomenon of earth resistance often appears in high soil resistivity areas such as northern China and hills, mountain area, has brought big hidden danger for device security, personal safety; In addition, in recent years, the district arranges compactness along with the transformer station station, and floor space is more and more littler, makes the earth resistance of traditional form more be difficult to satisfy design and construction requirement.
The patent No. is called the technical scheme of " ion earthing rod " for a kind of name is provided in 03205158.1 the utility application text, 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.
The utility model patent ionic earthing array ionic earthing array of application number 200820120553.0, in the contact tube of closed at both ends, hold the electrolytic ion compound, on the tube wall of contact tube, weld lead-out wire, on the tube wall of the middle and lower part of contact tube, offer the ion-exchange hole, on the tube wall of the top of contact tube, offer air-vent, envelope has adhesive plaster on ion-exchange hole and air-vent, is furnished with filler outside contact tube.
There are common problem in actual applications in above-mentioned ion earthing product and unlisted patented product: first problem in useful life.Because the degree of the reduction of soil resistivity and useful life and filler dosage are proportional substantially.In high soil resistivity, the soil resistivity long-term stability is reduced in the rules claimed range, and reach useful life more than 30 years, fixedly the ion earthing rod of filler is difficult to meet the demands; It two is hydrolysis problem of conductive ion.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; It three is problem of environmental pollutions.Filler in this barred body has certain contamination to environment, may cause environment difficulties; It four is etching problems of earth electrode case material.Because the residing environment of ion grounding electrode material is serious corrosive environment, the housing life-span that brings thus also is affected.As adopting anti-corrosion copper material or stainless steel to cause costing an arm and a leg, cost rises, and can not prevent the generation of corroding.
Summary of the invention
The purpose of this utility model is the problem that prior art exists is solved, and a kind of refilling type, simple in structure, easy to use, environmental friendliness and the significant ground network of resistance reducing effect high-efficiency environment friendly ion grounding electrode are provided.
Realize that the above-mentioned purpose technical scheme is:
Has a hollow corrosion resistant metal tube body; hollow corrosion resistant metal tube body inside is filled with the resistance-lowering material of compound prescription; be provided with the earth terminal that links to each other with ground network and anti-corrosion protection device at metal tube main body outer wall, have on metal tube main body top for filling cap of filling resistance-lowering material and the insulation stake that is enclosed within the top.
Hollow corrosion resistant metal tube body adopts galvanic anode protection, perhaps adopts impressed current cathodic protection.
Described hollow corrosion resistant metal tube cylinder bottom has the some little permeability hole that makes conductive ion and moisture turnover.
The utility model has the advantages that: 1. this ion grounding electrode compound resistance-lowering material of filling can be filled repeatedly, useful life in theory can with the same life-span of transformer station; 2. the result of 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. the loading of compound resistance-lowering material and proportioning can be regulated according to the height of earth resistance, guarantee the conductivity effect of soil; 4. compound resistance-lowering material composition with make land used soil and underground water composition roughly the same, so can guarantee environmental nonpollution; 5. useful life, overlength and effectiveness were lasting.
