Abstract
The utility model discloses a conducting grounding rod, which belongs to the field of grounding devices. The conventional grounding rod products have the defects of short service life, easiness for corrosion, and the like. The conducting grounding rod comprises a steel core, a copper layer and a zinc-base alloy layer; the diameter of the steel core is 5.0-20.0 mm; the copper layer covers the steel core; the thickness of the copper layer is 0.2-0.5 mm; the zinc-base alloy layer covers an external surface of the copper layer; and the thickness of the zinc-base alloy layer reaches 0.5-1.5 mm. By the utility model, the corrosion prevention and conduction performances are enhanced; the service life is prolonged; and the tensile strength is also improved simultaneously.
Description
Technical field
The utility model belongs to the conductive grounding device field, and is especially relevant with a kind of conductive earthing rod.
Background technology
Conductive grounding device is the key facility of electric power grounding grid and building ground network, buries underground undergroundly because of main body facility, so its corrosion is the problem that needs emphasis to solve always.The existing earth rod barred body that is used for provided underground mostly covers steel or zinc by single iron, copper and covers steel and constitute, in the above-mentioned earthing material, at first, ferrous material contacts with surrounding soil or water environment, cause the earth electrode corrosion very fast, can not reach long-term safety effective grounding purpose.Secondly, uses a large amount of copper as steel core cover the body material, because of copper can cause heavy metal pollution, and cost an arm and a leg, therefore also use on a large scale as yet.Once more, be that the zinc of characteristics covers steel with the cathodic protection, the specific area of having relatively high expectations at antiseptic property can't meet the demands.
The utility model content
The purpose of this utility model is at existing deficiency short, that easily be corroded etc. and to have proposed a kind of anticorrosion electric conductivity excellent and the earth rod of better tensile strength arranged in useful life in the above-mentioned prior art.For this reason, the utility model is by the following technical solutions:
A kind of conductive earthing rod, comprise that steel core and founding are coated on the copper layer on the steel core, is characterized in that: described conductive earthing rod also comprises the zinc-containing alloy layer, the zinc-containing alloy layer is coated on described copper layer outer surface.
As to technique scheme further replenish and perfect, the utility model also comprises following supplementary technology scheme:
Described steel core diameter is 5.0～20.0mm, and described copper layer thickness is 0.2～0.5mm, and described zinc-containing alloy layer thickness is 0.5～1.5mm.
Further, described steel core diameter is 9.0mm, can also be 15.0mm.
Further, described copper layer thickness is 0.3mm, and when described zinc-containing alloy layer thickness was 0.5mm, earth rod reached best rust-proof effect.
Use the utility model can reach following beneficial effect: the utility model is because of using steel core, and makes the tensile strength height of earth rod; Mandrel body covers the form of copper in adopting, and is prolonged the useful life of earth rod greatly, and strengthened the big electric current safety discharge capacity of earth rod greatly; Zinc-containing alloy secondary coating, wherein alloying component has influenced the polarization and the passivation behavior of anode and cathode, thereby impels the corrosion resistance of earth rod to obtain raising greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the Fig. 1 in the accompanying drawing, embodiment of the present utility model is described in detail.

2, the steel core 1 after polishing is carried out the founding of copper layer 2, make copper layer 2 reach the coating thickness of 0.3mm;
3, copper is covered the rod iron body and carries out the secondary sanding and polishing after, carry out the continuous casting of the outer zinc-containing alloy of barred body again, and make the thickness of coating zinc-containing alloy layer 3 reach 0.5mm, and after twice metallic cover, finally become the ground connection barred body of bimetallic coating.
Embodiment 2:
1, cut-off directly carries out alkali cleaning pickling grinding process for the steel core 1 of 9.0mm;
2, the steel core 1 after polishing is carried out the founding of copper layer 2, make copper layer 2 reach the coating thickness of 0.3mm;
3, copper is covered the steel wire body and carries out the secondary sanding and polishing after, carry out the continuous casting of the outer zinc-containing alloy of barred body again, and make the thickness of coating zinc-containing alloy layer 3 reach 0.5mm, and after twice metallic cover, finally become the ground connection barred body of bimetallic coating.
