Description
Technical field
The utility model relates to a kind of ground connection and falls resistance module metal electrode erosion protection system.
Background technology
Facilities such as transmission line, communications tower, microwave tower; Often be in the environment of high soil resistivities such as high mountain, sand ground, Gobi desert; Its ground network plays lightning protection, earial drainage; The middle effect of protection installations and facilities safety, and the earth resistance of ground network height has determined directly whether the protective effect of ground network is effective.Usually the earth resistance of ground network need reach below 10 Ω, could effectively prevent thunderbolt.Area at high soil resistivity; Ground network must adopt suitably falls the resistance measure and could guarantee that the earth resistance of ground network is in below 10 Ω; Thereby, fall the place that resistance facility and material be widely used in high soil resistivities such as high mountain, Gobi desert, sand ground like earthing module, grounded resistance reducing agent, earth rod etc. and come on the ground network of facilities such as reduction equipment, building.
Because it is underground that ground network and these resistance-lowering materials all are embedded in, soil environment must be brought certain corrosion to these materials.Usually be positioned at subsurface 30-80cm place in ground network and ground connection resistance-lowering material, this place is because interior moisture of soil and oxygen freedom are unobstructed, so the corrosion situation is serious relatively.
Earthing module is to be processed by the material of low-resistivity, metal electrode, and metal electrode material and low-resistance module body storeroom can form potential difference by nature, in case when the aqueous vapor condition maturity, very easily form galvanic effect.And metal electrode must corrode as anode material.
The metal electrode of earthing module is as the bridge that connects earthing module body and ground network; If the stability that heavy corrosion or fracture will inevitably influence the earth resistance of ground network takes place; Even have influence on the safe operation of building, equipment, facility, bring potential safety hazard and causality loss.
In the metal electrode of earthing module is come in and gone out a segment limit of earthing module body, be exactly the key area that corrosion galvanic cell forms, very easily corrode under the aqueous vapor effect in this zone, the metal electrode of damage earthing module.
The utility model content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of ground connection to fall resistance module metal electrode erosion protection system, effectively solves grounding electrode anticorrosion problem.
For realizing above-mentioned purpose; The concrete scheme of the utility model is: resistance module metal electrode erosion protection system falls in a kind of ground connection; It comprises earthing module body and earthing module metal electrode; Earthing module metal electrode discrepancy earthing module body position is in this section metal electrode and is provided with one or more layers insulating corrosion material, and the insulating corrosion material is fixed on the position that is connected with the earthing module body on the metal electrode of earthing module.
The beneficial effect of the utility model is: possess protective earthing module metal electrode and avoid the corrosion of earthing module body, do not influence original earthing module construction, can not increase workload than the construction of existing ground network; Cost is lower, can too much not increase the investment level; Prolong earthing module and use useful life, guarantee the resistance reducing effect continuity of ground network, reduce the situation that ground network repeats to construct.Improve ground network overall operation security reliability; Can not reduce requirement to the electrical characteristic of ground network.

The structural representation of resistance module metal electrode erosion protection system falls in Fig. 1 for the utility model ground connection.
Embodiment
For the technological means that makes the utility model is easy to understand understanding with reaching purpose, further set forth the utility model below in conjunction with specific embodiment.
Referring to Fig. 1; Resistance module metal electrode erosion protection system falls in a kind of ground connection; It comprises earthing module body 1, earthing module metal electrode 2; Saidly on earthing module metal electrode 2 is come in and gone out one section metal electrode of earthing module bodies 1, be provided with a kind of insulating corrosion material 3, insulating corrosion material 3 is fixed on the metal electrode 2 of earthing module.
Earthing module body on earthing module round metal steel electrode and metal electrode intersection; On one section heat-shrinkable T bush of pyrocondensation; Adopt super glue stationary heat Heat-Shrinkable Tubings then; Utilize this metal electrode processed finished products earthing module, promptly prepare a kind of ground connection and fall the etch-proof measure of resistance module metal electrode.
This novel another scheme; Earthing module body on earthing module round metal steel electrode and metal electrode intersection; Brushing one deck insulation glue; At one section heat-shrinkable T bush of this place's pyrocondensation, utilize this metal electrode processed finished products earthing module again, promptly prepare a kind of ground connection and fall the etch-proof measure of resistance module metal electrode.
Insulating material can be a kind of, multiple structure, can be other insulating material such as heat-shrinkable T bush, heat shrinkage film, insulating cement.Fixed form can adopt modes such as pyrocondensation, stickup, gluing, welding, riveted joint, compacting, colligation, and the earthing module metal electrode can be other materials such as galvanizing by dipping round steel, galvanizing by dipping band steel, steel galvanizing by dipping screw-thread steel, copper covered steel, copper, stainless steel, zinc Baogang.The earthing module body also can be plum blossom cylinder, other shape such as cylindrical, square.
The utility model is not restricted to the described embodiments, and the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.
