Description
Technical field
The utility model relates to Lightning protection, espespecially a kind of corrosion-preventing and resistance-reducing grounding pole.It is widely used in the conglomerate grounding system engineerings such as electric power, track traffic, military project, communication, oil, petrochemical industry, municipal administration, especially for solve the mountain area rock of high soil resistivity in grounding system engineering, dry sandy soil area resistance problem is fallen, and solve high corrosion the adverse circumstances such as seashore, salt lakeside resistance and Anticorrosion Problems fall.
Background technology
Earthing device is the important component part of lightning protection facility, by earthing device, the overcurrent scurried into from arrester downlead is imported the earth.The electric conductivity of earthing device and permanent dependability are to available protecting electric installation and build the very crucial safely of thing structural steelwork.
The adverse circumstances such as mountain area rock, dry sandy soil, the forthright soil of high burn into high resistance are the difficult problems in grounding system always, relative under other environment, above-mentioned adverse circumstances cause usually as the corrosion aggravation of earthing material, earth resistance cannot reach the stubborn problems such as regulation requirement.
1, the corrosion aggravation problem of earthing material:
In order to solve the problem of the main Grounding Grid aggravation of highly corrosive soil, present stage adopts two kinds of methods-----usually
Method one, strengthens the sectional area of Steel material, to tackle the reality of its aggravation corrosion.But corrosion is uneven, strengthen the sectional area of Steel material just based on anticorrosion in theory, corrosion occur time normally a certain section be corroded after, can continue to increase the weight of this section of corrosion, thus cause that earthing material partial cross section is long-pending very littlely even to rupture, make grounding system lose the ability of releasing to overcurrent, thus cause great potential safety hazard, inadvisable.
Method two, adopts the resistant material such as copper material or copper facing material to substitute steel.We know that copper material has corrosion-resistant, the advantage such as conductance is high, Heat stability is good relative to steel, but substitute steel costly with copper material or copper facing material, although earth electrode corrosion effect slows down, life-span increases, but will reliably be connected with building, when the reinforcing bar in building concrete is connected with the main earth mat of copper material due to main earth mat, reinforcing bar forms electrolytic cell reaction as anode, exacerbate the corrosion of building reinforcing bar, therefore greatly jeopardize safety and the life-span of building, inadvisable.
2, earth resistance cannot reach regulation requirement problem:
Earth resistance is the whether satisfactory most important index of measurement grounding system, but above-mentioned severe soil environment, there is high resistivity, engineering generally has for the solution of high soil resistivity and increases earth mat level or vertical contact area and lay and soil removal and replacement.
About increase earth mat level or vertical contact area, we know that composite earthing network can not increase contact area simply, and the first, because ground network lays limited area, relates to the problems such as expropriation of land, usually can only lay earth mat within the specific limits.Its two be because impulse current effective length be limited, as everyone knows, ground network earial drainage function function in impulse current effective length is maximum, when ground network is greater than its effective length, ground network earial drainage function will significantly weaken, and substantially can ignore the function of its earial drainage.Therefore it is inadvisable.
About soil removal and replacement, the native stone excavation difficulty of soil removal and replacement is large, engineering drops into huge, and effect is often just temporary transient, because we can only change the soil of a part, but regional soil all can not be changed, this just causes along with soil change for many years, soil erosion, the generation of the situations such as crustal movement, soil returns the adverse circumstances of highly corrosive high resistivity.Huge investment is wasted, therefore it is inadvisable.
