Abstract
The utility model relates to an earthing bar, which comprises a steel core and a copper layer which is molded at the outer side of the steel core through an extrusion method, wherein the thickness of the copper layer is 0.7-0.8mm, and the cross sectional area of the copper layer accounts for 13-21 percent of the cross sectional area of the earthing bar. In the utility model, a copper-clad steel structure is adopted by the earthing bar, therefore, the material cost can be effectively reduced, electroplating is not needed and the environment cannot be polluted; and moreover, the copper-clad steel earthing bar not only has high strength and high heat resistance of steel but also has high electrical conductivity and good corrosion resistance, and the service life of the earthing bar can be prolonged.
Description
Technical field
The utility model relates to a kind of device power ground, particularly a kind of ground connection busbar.
Background technology
For preventing that building from suffering that thunder and lightning destroys, usually ground connection row is embedded in the building below in the prior art, and links to each other with lightning rod by lead-in wire, when building connect dodge thunderbolt after, the thunderbolt energy will be put in the earth along going between to the ground connection drainage.Widely used in the market ground connection row is the cathode copper material, and its material cost is higher, and the method that also has partial earthing row to adopt aluminium row or employing galvanoplastic to electroplate the copper layer of 0.2～0.3mm in the steel core outside is made, thereby reduces material cost.Yet adopt the row of galvanoplastic production of copper Baogang, owing to will use electrolyte, therefore can cause the pollution of serious environment, in addition, the finished product top layer that this method is produced still can residual fraction electrolyte, also can pollute ambient soil when underground when burying underground; In addition, the copper covered steel row's that galvanoplastic are produced copper layer thickness is very thin, not corrosion-resistant, and after the copper layer corrosion on top layer, the steel core of internal layer will soon be corroded, and therefore often can't reach ground connection row's design period-20 year.
Summary of the invention
The purpose of this utility model provide a kind of pollution-free, cost is low and corrosion resistant ground connection row.
For achieving the above object, the technical solution adopted in the utility model is: a kind of ground connection row, it comprises steel core and is molded over the copper layer in the described steel core outside by extrusion that described copper layer thickness is 0.7～0.8mm.
Further, the cross-sectional area of described copper layer account for described ground connection row cross-sectional area 13%～21%.
Preferably, the cross-sectional area of described copper layer account for described ground connection row cross-sectional area 15%.
Further, the material of described steel core is a mild steel, and preferably, the material of described steel core is the Q195 steel.
Further, described ground connection row's cross section is a rectangle.
Because the technique scheme utilization, the utility model compared with prior art has following advantage: ground connection row of the present utility model adopts the copper covered steel structure, can either effectively reduce material cost, does not need again to electroplate, and can not pollute environment; In addition, copper covered steel ground connection row not only has the high strength and the high-fire resistance energy of steel, and the thickness of copper layer reaches 0.7～0.8mm, therefore has high conduction and good corrosion resistance, can improve the useful life that ground connection is arranged.Can reach ground connection row's parameters standard through the advance copy utility model, the cross-sectional area that the cross-sectional area of copper layer accounts for ground connection row is that 15% copper covered steel ground connection row's electric conductivity is compared with fine copper ground connection row, it exchanges ampacity is fine copper ground connection row's 85%, is more or less the same.
Description of drawings
Accompanying drawing 1 is a sectional view of the present utility model;
Wherein: 1, steel core; 2, copper layer.
Embodiment
Shown in accompanying drawing 1, a kind of ground connection row, it comprises steel core 1 and passes through the copper layer 2 of extruder extrusion modling in described steel core 1 outside, the copper layer of being told 2 forms a week of sealing in described steel core 1 outside, described copper layer 2 and described steel core 1 metallurgical binding, described copper layer thickness is 0.7～0.8mm.
Described copper covered steel horizontal row cross section is a rectangle as shown in the figure, and it improves mechanical strength, and it is simple to lay welding operation, and has improved contact area, makes the easier rapid release of electric current.And the cross-sectional area of described copper layer 2 account for described copper covered steel row cross-sectional area 13%～21%.Preferably, the cross-sectional area of described copper layer account for described ground connection row cross-sectional area 15%.
Described steel core is the Q195 steel.
Copper covered steel ground connection of the present utility model row's price is than cheap many of fine copper ground connection row, and complete alternative fine copper ground connection row reaches the purpose that reduces product cost.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
