Description
Technical field
The utility model belongs to power system security device technology field, relates to a kind of earth connection, relates in particular to three layers of compound earth connection of a kind of zinc magnesium alloy copper clad steel.
Background technology
Zinc magnesium alloy has excellent corrosion resistance, under extraneous environmental corrosion, zinc can produce the coating layer of one deck densification under the effect of magnesium, extraneous electrolyte solution further contact and infiltration have been intercepted, and the corrosion potential of kirsite is shuffled, corrosion current obviously descends, and has delayed largely the corrosion process of zinc.And copper is as the earth connection material, has good electric conductivity, if copper and zinc magnesium alloy are combined with each other, also can strengthen the corrosion resistance of zinc magnesium alloy, because in electrochemistry, copper than hydrogen have higher positive potential (+3.5V), therefore copper has higher thermodynamic stability, the unpolarizing of hydrogen can not occur, so the complex earthing material has superpower corrosion resistance, in addition, its resistance is also far below common galvanized steel.Moreover, the intensity of steel, and can greatly save project cost when assurance is safe and reliable, therefore can satisfy the requirement of all kinds of grounding safeties designs fully.
Summary of the invention
The purpose of this utility model is that to overcome in prior art corrosion resistance and electric conductivity undesirable, perhaps be subject to the restriction of range of application, and expensive, the defectives such as useful life is short, a kind of have simultaneously extra-strong corrosion resistant and superior electrical conductivity energy are provided, can be applicable to various grounding safety occasions, greatly lengthen useful life again, and have the intensity of steel, can greatly save three layers of compound earth connection of zinc magnesium alloy copper clad steel of project cost when assurance is safe and reliable.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Three layers of compound earth connection of a kind of zinc magnesium alloy copper clad steel comprise three-layer composite structure, are respectively from the inside to the outside steel core, copper layer and zinc magnesium alloy layer.Zinc magnesium alloy has excellent corrosion resistance, and under extraneous environmental corrosion, zinc can generate the coating layer ZnCl of one deck densification under the effect of magnesium

6, having intercepted extraneous electrolyte solution further contact and infiltration, and the corrosion potential of kirsite is shuffled, corrosion current obviously descends, and has delayed largely the corrosion process of zinc.And copper is as the earth connection material, has good electric conductivity, if copper and zinc magnesium alloy are combined with each other, also can strengthen the corrosion resistance of zinc magnesium alloy, because in electrochemistry, copper than hydrogen have higher positive potential (+3.5V), therefore copper has higher thermodynamic stability, the unpolarizing of hydrogen can not occur, so the complex earthing material has superpower corrosion resistance, in addition, its resistance is also far below common galvanized steel.Moreover, the intensity of steel, and can greatly save project cost when assurance is safe and reliable, therefore can satisfy the requirement of all kinds of grounding safeties designs fully.
As preferably, the zinc magnesium alloy layer thickness is 0.5～20.0mm.
As preferably, the thickness of zinc magnesium alloy layer further is chosen as 1.0～10.0mm.
As preferably, the thickness of copper layer is 0.025～10.0mm.
As preferably, the thickness of copper layer further is chosen as 0.25～1.0mm.
As preferably, between steel core and copper layer, be combined with each other by horizontal casting between copper layer and zinc magnesium alloy layer.Horizontal casting can be integral steel core and copper layer, copper layer and the combination of zinc magnesium alloy layer, and performance advantage separately, be greatly enhanced the combination property of earth connection mutually.
It is undesirable that the utility model has overcome in prior art corrosion resistance and electric conductivity, perhaps be subject to the defectives such as restriction of range of application, a kind of have simultaneously extra-strong corrosion resistant and superior electrical conductivity energy are provided, can be applicable to various grounding safety occasions, greatly lengthen useful life again, and have the intensity of steel, can greatly save three layers of compound earth connection of zinc magnesium alloy copper clad steel of project cost when assurance is safe and reliable.The utility model has good application prospect in power system security device technology field.
