Description
Technical field
The utility model relates to field of power, particularly a kind of 10 KV distribution net earth rods.
Background technology
Earth rod, has another name called earth electrode, ground network.Earth rod is to improve earthing conductor inner conductive performance, reduces the outside soil resistivity of earthing conductor and be the designed production of theoretical foundation.Product has that easy construction, floor space are little, non-environmental-pollution, long service life and the advantage such as resistance is low.Due to Rural Power Distribution Network engineering, point is many, wide, and each local landform, soil property are different, soil resistivity difference, and earth resistance again cannot Accurate Determining.So must take to reduce the technical measures of earth resistance, can increase like this earial drainage area of earth electrode, the surface that reduces earth electrode is in contact with it the contact resistance between soil, falls low-resistance object thereby reach.Common earth electrode dryness contact, when dry and moist, earth resistance big rise and fall; Due to corrosiveness, As time goes on earth resistance rises comparatively fast, anticorrosion poor in addition, every 3 to 5 years, need re-start soil transformation.At present, there is no the earth rod of stable performance.
Along with the development of electric power system, also more and more higher to the requirement of ground connection.For a long time, reliable, stable grounding system, is to maintain equipment stable operation, the basic guarantee of guarantee equipment and personal security, the material that the key of grounding system long-term safety reliability service is to select quality better be connected reliably.
Utility model content
The purpose of this utility model is in order to be grounded system long-term safety reliability service, and spy provides a kind of 10 KV distribution net earth rods.
The utility model provides a kind of 10 KV distribution net earth rods, it is characterized in that: 10 described KV distribution net earth rods, comprise barred body 1, cross bar 2, Wiring device 3, protective layer 4;
Wherein: barred body 1 is connected with cross bar 2 is vertical, Wiring device 3 is fixedly mounted on cross bar 2, and protective layer 4 is coated on barred body 1 surface.
Described barred body 1 surface is with helical raised structure.
Described barred body 1 bottom is pointed structure.
Described cross bar 2 is two, is threaded connection respectively with barred body 1.
Described Wiring device 3 is platy structure with holes, or screw lock structure.
Described barred body 1 is 1 to 10 bar structure, unnecessary 1 o'clock of radical, between with jockey.
Described protective layer 4 is zinc coat, and thickness is divided into four kinds of 0.127mm, 0.25mm, 0.33mm, 0.50mm, 1.0mm, and for adapting to different soils, resistivity, lower than 0.059 Ω mm, meets the low-resistance requirement of special occasions.
Cross bar 2 is easy for installation, uses for handle or while knocking.
Advantage of the present utility model:
Increase the contact area of earth rod and the earth, effectively lowered earth resistance, avoided induced voltage, the injury to workmen such as Leakage Current.Can improve earthing conductor inner conductive performance, reduce the outside soil resistivity of earthing conductor.Easy construction, floor space are little, non-environmental-pollution, long service life.By the ion release effects of electrode interior and outside packing material, improve the contact environment of electrode and Soil Surrounding, reach the object of falling resistance, implement common earthing method and reach low earth resistance.
Ground connection stability, zinc-plated have an impact anticorrosion, that climate does not change well, and earth resistance enters continual and steady state after construction completes one week, not affected by the dry wet of soil, can not rise along with the time.Reduce soil resistivity zinc-coated spiral earth rod resistance reducing effect obvious, construction is simple, and quantities is little, and comprehensive cost is lower compared with low technical level, and quantities is little, has technology ensuring.It is convenient to install, and construction is simple, can craft or mechanical execution, and cheap.Due to kelvin effect and the zinc material exclusive Anticorrosive Character of electric current in conductor, therefore conductance, anticorrosive rate is better than other ground connection product; Cost is low, most widely used.Be applicable to rural power grids 10KV distribution engineering, application surface is the widest.Surface zinc layer, corrosion resistance is strong, is applicable to the soil environment of different PH, resistivity, humidity, temperature, construct simple and easy, convenient transportation, special welding manner connects, and quick and easy, joint is firm, good stability.Zinc-coated spiral earth rod is because this zinc layer can not come off or split when the deep drilling, even if gap can not occur when bending rod yet.Good and the useful low earth resistance of galvanized steel earth rod anticorrosion function.
