Description
Technical field
The utility model relates to a kind of zinc-copper Baogang body anodize lightning protection anti electrostatic grounding system ground system of covering.
Background technology
The anodize lightning protection, antistatic, instrument and electrical ground system, be for protect that building etc. avoids thunderbolt with power equipment antistatic, the device of anticorrosion and instrument.Lightning protection electrical equipment and electric, instrumentation anodize grounding system is widely used in communications industry, electric power system, building system, oil, chemical industry, army's construction is executed, and the railway system waits a plurality of industries.At building; electric; the instrumentation grounding end; with metal wire be embedded in underground one and couple together, utilize the earth electrode electric discharge of metal bar, thus make cloud layer with electricity or the static of electric meter directly import the earth protective device and instrument; thereby high-rise can be not accidents caused; simultaneously because cover the zinc-copper coated grounded pole, in the zinc layer anodic protection effect is arranged, can protect electric equipment not to be subject to electrochemical effect and corrosion is corroded.The anodize lightning protection, antistatic, instrument and electrical ground system specification must meet the GB standard, and the lightning protection earthing system specification that other lightning protection of each grade needs is different.
Traditional lightning protection earthing system is all irony, irony gets rusty easily, and not corrosion-resistant, conductive effect is bad, stability is very poor, the electric conductivity of copper is fine, corrosion resistance, but the price of copper is more expensive, poor toughness, can not directly be driven underground because of the ground prime factor in the most areas of China, so cause operating expenses large, be difficult for promoting.
The utility model content
The technical problem that the utility model solves is providing a kind of zinc-copper Baogang body lightning protection earthing system that covers, to solve the shortcoming in the above-mentioned background technology.
It is a kind of novel ground connection product that my company researches and develops according to the petrochemical system market demand that TD-DDTX covers the zinc-copper coated grounded pole, and it take cathode copper special steel and special zinc is raw material, by special process, forms double metallic composite material Baogang.This product combines the advantage of zinc band anode and traditional zinc-plated steel earthing material; both there is the high strength of steel, higher thermal stability; the function that there is again cathodic protection; contact resistance is less than 0.5Q; the corrosion resistance of copper far away higher than steel matter and than ground connection and cathodic protection separate do more scientific, more economical, service life is longer, the life-span generally can reach more than 50 years.The copper covered steel earth electrode adopts international state-of-the-art composite electroformed technique, the cathode copper molecule that is 99.9% by purity covers low charcoal steel core surface and is made, its surface copper coating degree is 0.254rVIm, steel core is the bar that meets the diameter requirement, there is the tensile strength up to 600N/mm for the steel tool used, so that earth rod light depths at the bottom of arrival point under the impulsive force by external, and guarantee normally to use more than at least 50 years.Cover the compound earth electrode of zinc-copper Baogang and can be widely used in ground connection and the common occasion existed of cathodic protection, also can be respectively as ground connection product and cathodic protection product.
A kind of zinc-copper Baogang body lightning protection earthing system that covers; comprise steel core, copper layer, zinc layer, earth electrode; cross layer of copper on described steel core; the appearance of copper layer is covered one deck zinc; the earth terminal of lightning protection anti electrostatic grounding system is provided with earth electrode; earth electrode is for the protection of the lightning protection anti electrostatic grounding system, and the thickness of described copper layer is 0.5--5mm, and the thickness of described zinc layer is 0.5--5mm.
When the utility model is used, earth electrode is imbedded underground, the other end is arranged on the facility top that building maybe will be protected.
Beneficial effect:
The utility model electrical conductivity is good, and corrosion resistance is strong, and copper layer and steel core perfect adaptation are of a specified duration useful life.
1, TD-DDTX covers the compound earth electrode of zinc-copper Baogang and take special steel as steel core, has intensity and the thermal stability of steel, guarantees ground connection earial drainage function;
2, zinc is as the coating metal, and its electric conductivity is 2.5 times of steel, and conductivity is more excellent;
3, zinc, as the coating metal, has stronger corrosion resistance, greatly increases the service life;
4, because certain thickness zinc layer can be used as the sacrificial anode body, protection earth mat, underground metal structures and relevant steel equipment etc.The heat release welding point;
5, the copper layer that covers the copper covered steel below zinc reaches the 0.3mm. anti-corrosive properties far above steel.Conductivity is splendid.Greatly extended the life-span of earth electrode.Equal to have had to earth electrode anticorrosion, the dual fail-safe of cathodic protection.Start the industry beginning.Real anticorrosion grounding body.
The uniform thickness of copper plate---earth electrode copper plate each point uniform thickness 0.254rnm.This thickness guarantees that the latter made bottom of thread of copper facing is all covered.
The strong degree of adhesion of copper plate---earth electrode to be measured is clipped between the tiger’s jaw pincers, and the diameter that the distance between jaw equals the utmost point deducts 1-2mm.When polar region is extruded, the tiger’s jaw pincers can cut with it the coating of contact, and the remainder coating on surface can not peel off, but such coating can guarantee earth electrode screw thread in rolling after copper facing.
The plasticity of coating---will extremely crooked 30 degree.After tested, crack and peeling off does not appear.Electroformed copper earthing pole utilizes electrolysis tech, makes steel core and copper electroplating layer reach the combination of molecule, has solved with regard to effective the problem that steel core easily is corroded like this.
In same time, three kinds of utmost points is subject to extent of corrosion (the copper electroforming coated grounded pole that rod iron, hot dip zincode, copper layer thickness are 0.254mm), copper electroforming coated grounded pole 10 annual corrosion rates 11%, 20 to be only be 25%, and rod iron corrosion in 20 years is that 70% zinc-plated rod is 60%.
Through contrast, experiment conclusion, when the copper electroforming coated grounded pole has reduced mounting cost, also compare and have the following advantages with other earth rod: 1, dark 4, the long service life of strong by 2, the simple installation 3 of corrosion resistance, ground connection.
