The non-metallic ion grounding body comprises a body and two metal electrodes; a closed ion cabin (4) is arranged in the body (2); conductive ion powder (5) is filled in the ion cabin; the two electrodes (1) are fixedly inserted on the body (2). The non-metallic ion grounding body has the advantages of low grounding resistance rate, no influence by the change of soil humidity, high capacity for bearing large-current impact, good current radiating effect, high corrosion resistance capacity of the electrodes, convenient exchange, and the like. The invention relates to a grounding protection device which can be broadly applied to the industries like broadcasting, communication, electric power, railways, civil aviation, oil and gas transmitting, chemical engineering, and the like, and is especially suitable for the areas with higher soil resistance rates like highest peaks, deserts, and the like.
Description
Technical field:
The present invention relates to a kind of earth protective device, relate in particular to a kind of earth electrode.
Background technology:
As everyone knows, traditional material that earth electrode adopted mostly is shaped steel greatly, because the condition restriction of edaphic condition and earth mat construction site only is difficult to reach desired grounding resistance with traditional earthing material, therefore having to lay resistance-lowering material reduces earth resistance; But relatively more difficult at the local site operation that conditions such as mountain region, desert are more abominable, resistance reducing effect is also undesirable, and resistance-lowering material is also very fast to corrosion of metal.For this reason, at present many producers all are that mode by die casting is wrapped in resistance-lowering material and constitutes earthing module on the shaped steel.
Earthing module is used widely rapidly because of it has characteristics such as easy construction, earth resistance be low; But in the process that reality is used, earthing module has also exposed some problems gradually:
1) it is undesirable to bear high current impulse withstanding capability;
2) owing to adopted whole electrode to pass the structure of resistance-lowering material, the corrosion rate that therefore is wrapped in the electrode cores in the resistance-lowering material is very fast, and the grounding resistance bounce-back is bigger, and shorten useful life greatly;
3) resistance reducing effect is not obvious.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the present invention aim to provide a kind of earth resistance little, bear that high current impulse withstanding capability is strong, the non-metallic ion grounding body of long service life.
To achieve these goals, the present invention by the following technical solutions: it comprises body and metal electrode; Be provided with airtight ion bin in the body, be filled with the conductive ion powder in this ion bin; Two electrodes fixedly are inserted on the body.
Ion bin has two at least; Electrode is fixed on the body by screw thread; Be provided with the separator of conduction between electrode and the body; Ion bin is sealed by hatchcover.
Compared with the prior art, the present invention is owing to changed the body of original entity structure into be provided with closed cavity (ion bin) hollow-core construction on the basis of traditional earthing module, and in this cavity, load the conductive ion powder, therefore can reduce the earth resistance rate effectively; Simultaneously and since will be originally one whole metal electrode in the body changed two electrodes separated from one another into, and between electrode and body, set up separator, therefore not only saved metal electrode consumption, but also delayed time of electrode corrosion greatly.Make a concrete analysis of as follows:
1) the self-resistance rate is low
Because body is formed by the graphite material high temperature sintering, so the earth resistance rate of body is very low, has only 5～15 μ Ω .m.
2) the tolerance high current impulse withstanding capability is strong
Because whole body is a good conductor, and the contact resistance of body and soil is very little, thus to electric current to dredge performance strong, the impact that can carry hundreds of kiloampere thunder-strike currents or thousands of amperes of short circuit currents.
3) resistivity is not subjected to the influence that soil moisture changes
Owing on the body many pores are arranged, the conductive ion powder has very strong water absorption simultaneously, therefore body can absorb and store moisture when soil moisture is big, when soil during drying body can keep the skin wet by peripherad soil, thereby the humidity that can keep or improve soil is with the raising electric conductivity; Resistivity is highly stable.
4) diffusing stream is effective
Owing to can therefore can around body, form lasting, good some conductive channels by the peripherad soil slowly-releasing of the pore on the body, infiltration conductive ion after the hydrolysis of conductive ion powder; When heavy current impact, electric current can discharge rapidly and can not produce high earth potential counterattack by going deep into tree root shape conductive channel in the soil, enlarges contact area, further reduces the purpose of earth resistance thereby reach.
5) strong, the long service life of electrode resistance to corrosion, replacing are convenient
Owing to adopted the separator of conduction that electrode and body are isolated, can prevent that therefore moisture and conductive ion from infiltrating between electrode and the body, thereby slow down the extent of corrosion of that part of electrode that contacts with body effectively; Because electrode has adopted the mode that is threaded with body,, thoroughly overcome traditional earthing module causes whole failure of apparatus because of electrode defective in addition even if therefore electrode corrosion also can be convenient for changing later on.
Therefore 6), thoroughly overcome the variation of environmental factors such as traditional earthing module Yin Wendu, humidity and the defective of breaking easily, being out of shape even disintegrating because body has adopted high-sintering process.
7) because ion bin is sealed by hatchcover, can add the conductive ion powder very easily, therefore reusable.
