Abstract
The utility model discloses a novel anti-corrosion resistance reducing module, which relates to the technical field of grounding corrosion resistance and resistance reducing of an electric system. The technical scheme is that the anti-corrosion resistance reducing module comprises a feed connecting rod, a conducting module main body and an anti-corrosion electrode, wherein a feed connecting rod lead wire connecting end is an L-shaped structure, the conduction module main body is in a cylindrical shape or an oblong shape, the anti-corrosion electrode is in a ball-lack shaped structure, a rod core penetrates through the conducting module main body and is connected with the anti-corrosion electrode, the anti-corrosion electrode and the feed connecting rod are connected with the conducting module main body through a bolt, wherein grooves are fully distributed on the surface of the conducting module main body. The anti-corrosion resistance reducing module simultaneously has the behaviors of corrosion resistance and resistance reducing of an earth screen, has convenient construction, greatly lowers running and maintenance cost, has excellent stability, can reach 20 years of service span, has stronger water-absorbing quality and water-retention property, can keep water and gradually release water for long term, and leads the resistance reducing effect to keep relatively stable.
Description
Technical field
The utility model relates to the electric power system grounding anti-corrosion and falls the resistance technical field, the resistance module falls in specifically a kind of ground connection with anti-corrosion function, be mainly used in substation ground network and tower grounding device, play the effect that prevents the earth mat material corrosion and reduce earth resistance.
Background technology
Before the utility model proposes, various earth mat anti-corrosive apparatus are used widely, replace steel as national expenditures resistant material such as: U.S. such as copper, are used for ground system to make earth electrode, though improve 1～2 times of earth mat life-span, increase by 5～6 times of costs of investment; The anticorrosion employing hot galvanizing of earth mat steel, diffuse to form zinc-iron alloy layer between zinc and the iron and steel, be metallurgical binding, more firm than general coating combination, the zinc layer many decades that is exposed in the atmospheric environment can not come off, shortcoming be zinc coat when ingress of air and water, can produce slight electrochemical corrosion, in industrial pollution district and coastal area, the service life of zinc coat is very short; The mechanism of brushing anticorrosive paint is that ground network metal and soil media are isolated by coating, but do not influence ground network current drainage in soil media, the anticorrosive paint of brushing possesses the corrosion resistance to acid, alkali, salt, but, be difficult on large-scale newly-built ground network and use old ground network for many years, use because this technology is had relatively high expectations to the electric conductivity and the physicochemical property of coating.
Summary of the invention
The purpose of this utility model is exactly the defective at prior art, provides a kind of and be mainly used in the earth mat anti-corrosion protection, falls that the resistance ability is good, long service life, the stable and low corrosion-preventing and resistance-reducing module of construction maintenance cost.
At above-mentioned purpose, novel corrosion-preventing and resistance-reducing module provided by the utility model, its technical scheme is: comprise the feed pitman, conductive module body and anticorrosion electrode three parts are formed, the L-shaped structure of feed pitman lead-in wire link, cylindrical or the rectangle of conductive module body, anticorrosion electrode is segment shape structure, the rod core passes the conductive module body and is connected with anticorrosion electrode, anticorrosion electrode is connected with this body and function of conductive module bolt with the feed pitman, described conductive module body surface evenly is covered with a lot of groove, this plurality of grooves has increased the contact area of conductive module body and soil greatly, thereby increased diffusing flow area, and then reduced contact resistance.
Described conductive module body both sides are provided with 2～4 micropores, and anticorrosion electrode tip is provided with 1 micropore, and this micropore has strengthened the water absorption and the seepage of water of this utility model, and resistance reducing effect is kept relative stability.
Described anticorrosion electrode adopts active metal Mg, Zn alloy material; with provide cathodic protection current after earth mat is connected; make the ground net materials avoid corrosion; thereby be applicable to the area of low soil resistivity, seriously corroded; as coastal, salt-soda soil etc.; prolong useful life, guaranteed its safe operation, greatly reduced the construction maintenance cost simultaneously.
Operation principle of the present utility model is:
Anticorrosion electrode adopts the reactive metal composition to make, and plays the protective effect of sacrificial anode.In protected earth mat metal and the formed the earth battery of sacrificial anode, sacrificial anode is an anode, and its current potential is defeated by the current potential of protected metallic object;, protected earth mat metal is a negative electrode, like this; the anode metal consumption that is corroded, thus protected the earth mat metal not corroded.
The utility model is compared with the prior art, and shows that fully its superiority is:
At first, it is anticorrosion and fall the resistance effect that the utility model has earth mat simultaneously, and easy construction reduces operation expense greatly; Secondly, have advantages of excellent stability, can reach 20 years useful life; At last, have stronger water absorption and water-retaining property, can keep moisture and release gradually for a long time, resistance reducing effect is kept relative stability.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail,
Description of reference numerals is as follows:
1-feed pitman
2-conductive module body
The anticorrosion electrode of 3-
The utility model embodiment is as follows:
1) can carry out vertical embeddingly or level is embedding, burried depth should not be less than 0.8 meter, can suitably buried (it is following that extremely frigid zones should be embedded in frozen soil layer) for the less area of the area of high soil resistivity or deep soil resistivity;
2) under soil resistivity＜100 Ω m conditions, antiseptic effect is more good.To high soil resistivity (more than the 500 Ω m), should take other to fall the resistance measure and be used;
3) connecting line will carry out preservative treatment, can adopt corrosion-resistant conductive coating, electroconductive cement, resistance reducing agent etc.Also can directly use anticorrosive (copper, copper covered steel, selenium soil material etc.) consistent service life with module with the service life that guarantees connecting line;
Should inject sufficient moisture when 4) embedding, allow the abundant moisture absorption of module and soil, reach optimum efficiency as early as possible with the assurance module;
5) pole piece of conductive earthing module is connected to each other or when being connected with ground wire, should adopts two-sided welding, and weld length must not be less than 100mm.Do not allow rosin joint, leak weldering, guarantee the reliability that connects.
