The ground electrode body comprises a metal tube and electrolysis ion compounds; the metal tube is provided with a liquid outlet communicated with the electrolysis ion compounds in the metal tube. The anticorrosion and resistance-reducing ground electrode has the advantages of preventing the ground electrode from eroding and reducing the earth resistivity.
Description
Technical field
The utility model relates to a kind of corrosion-preventing and resistance-reducing earth polar.
Background technology
Earth electrode is the earth electrode that is exclusively used in earth resistances such as reducing electric equipment earthing device, ground network.Make the working earthing, safety ground, protective earthing etc. of electric equipment reach good ground connection effect, effectively guarantee the safety of electric equipment and the person under various service conditionss.It is widely used in electric power systems such as power plant, transformer station, transmission line; Industrial and mining enterprises such as metallurgy, chemical industry, oil coal; Communal facilitys such as communication, machine station, building.
Along with the high speed development of microelectric technique and the extensive use of computer technology, the requirement of electronic equipment earth resistance is improved day by day.And that earth electrode is embedded in is underground, the acid-base value of soil and the earth polar is produced ionization, decomposition with the existence meeting that is embedded in other underground metal.So under the condition without any protection, earth electrode can be corroded rapidly.Simultaneously, because earth electrode buries underground underground, so corrosion situation that can't the real-time inspection earth electrode is difficult to keep in repair timely or change.
Solution is the useful life that as far as possible prolongs earth electrode.Traditional method is at earth electrode surface plating anti-corrosion material, as hot galvanizing; This mode is just slowed down corrosion rate relatively, and in the high area of acid-base value, this earth electrode life-span only is 1 year; If weld bond is dealt with improperly, corrosion rate will be faster.Also the someone adopts the method for sacrificial anode, promptly uses with respect to strong, the active material of earth electrode reproducibility as anode, as zinc, magnesium etc.; At this moment, because of the difference of activity, ground connection is negative electrode very, and zinc, magnesium are anode, and the earth soil is electrolyte, constitutes a storage battery.In equipment running process, if exist corrosion promptly oxidized, then at first be that the high anode of reproducibility is earlier oxidized, i.e. elder generation's corrosion anode.Just corrode negative electrode after anodic attack is intact, thereby prolong the useful life of earth electrode.
But, as the earth electrode of electronic equipment,, require the earth resistance resistance very low because of the power consumption equipment withstand voltage level is low, in order to avoid when the leakage failure electric current, earth potential does not raise and causes counterattack to equipment too much.And actual earthing device, ground network seldom can take the good farmland with the layout of electrical network and electric equipment, usually run into salt-soda soil, the high soil of mountain region constant resistance rate, and this moment, earth resistance just can't reach design parameter.The method that solves manages to fall resistance exactly.Though sacrificial anode protection can prolong the useful life of earth electrode, can't realize falling resistance.
Traditional resistance method one of falling is the quantity that increases earth electrode, and in the high area of resistivity, effect is bad.Method two is to adopt the electrolysis earth polar.The electrolysis compound is injected tube electrode make the electrolysis earth polar of containing electrolyte.Electrolyte can make the high mountain geologic structure of original conductance extreme difference form good " passage of the tree root shape of conduction " to the depth direction infiltration of tor, and contact area is increased relatively, and soil resistivity is reduced, and discharge capacity improves.Though but resistance can fall in this method, can not change the corrosion of earth electrode, prolong the useful life of earth electrode.
The utility model content
The above-mentioned technical problem of the utility model for existing in the solution background technology, and a kind of corrosion-preventing and resistance-reducing earth polar that had both prevented that the earth electrode corrosion from can reduce soil resistivity is provided.
Technical solution of the present utility model is: the utility model is a kind of corrosion-preventing and resistance-reducing earth polar, its special character is: this corrosion-preventing and resistance-reducing earth polar comprises the earth polar body, the earth polar body comprises metal body and electrolytic ion compound, the electrolytic ion compound is arranged in the metal body, and the metal body is provided with the leakage opening that is communicated with electrolytic ion compound in the metal body.
Above-mentioned metal body is zinc matter body or magnesia body.
Above-mentioned metal tube end of body is provided with opening.
Above-mentioned metal tube end of body opening part is provided with end cap.
Above-mentioned earth polar body is one or more.
When above-mentioned earth polar body is a plurality of, connect by lead between the body of described earth polar.
Above-mentioned metal body is being provided with leakage opening near the place, end.
Above-mentioned leakage opening is one or more.
When being a plurality of, above-mentioned leakage opening becomes symmetric arrays.
The utlity model has following advantage:
1, effectively the protective earthing utmost point is not corroded.The utility model adopts the material of the metal body of zinc, magnesium conduct; therefore metal body itself has just constituted an expendable anode with respect to earth electrode; effectively the earth electrode of protective earthing device or ground network is not corroded; and can require the time of use according to earth electrode; the casting different-thickness also can connect a plurality of such metal bodys, so the utility model can effectively guarantee the time limit that earth electrode is not corroded as required.
2, can reduce near the resistivity of the soil of earth electrode.Electrolytic ion compound in the utility model metal body, by the moisture in the leakage opening absorption soil, become electrolytic solution through deliquescence and go into the soil, thereby surrounding soil resistance is reduced, make earth electrode better to the soil earth current of releasing from this leakage opening discharge currents.
