The invention utilizes the skin effect of large current, the inner shaping material can be composed of low-price hard components and is used for supporting the outer copper stranded wire, the area of the outer enclosure of the copper stranded wire is enlarged, and the current is released to the maximum extent. The external material uses the copper stranded wire as a medium for discharging current, so that the corrosion resistance is excellent, and the periodic maintenance cost is avoided; the conductive material has good conductivity and can well discharge current; in addition, the copper stranded wire has flexibility and good tensile property, and can avoid the snapping caused by foundation settlement and external force.
Description
Technical field
The present invention relates to grounding net of transformer substation technical fields, and web frame is grounded more particularly to a kind of steel core copper stranded conductor.
Background technology
Can grounding net of transformer substation be the important device of electric power safety operation, effectively run the peace for being related to electric system
It is complete to stablize.
Currently, the material of grounded screen mainly has two kinds of copper and steel.Wherein, Steel material grounded screen is cheap, but corrosion-resistant
Property it is poor, need periodically to be safeguarded, maintenance cost is high；And copper product grounded screen corrosion resistance and good, it need not be periodically
It safeguards, inductive effect is small, and its aerial drainage effect is better than steel, but price is high.
Invention content
The technical issues of solution of the present invention, is, provides a kind of steel core copper stranded conductor ground connection web frame, has very
Good corrosion-resistant and water conservancy diversion effect, and it is cheap.
In order to solve the above technical problems, the technical solution adopted in the present invention is, a kind of steel core copper stranded conductor ground connection is provided
Web frame comprising：The steel strand wires of internal layer are set to, and are set to the copper stranded conductor of outer layer.
Wherein, the steel strand wires include the steel conducting wire that multiply is mutually wound.
Wherein, the steel strand wires for being set to internal layer form shaping material, and the copper stranded conductor uniform fold of the outer layer simultaneously wraps
It is rolled on the outside of steel strand wires.
Wherein, the copper stranded conductor of the outer layer includes multiply copper wires arranged side by side, and the multiply copper wires are with one
Fixed angle is wrapped circumferentially around on the periphery of steel strand wires.
Wherein, it the angle ranging from the acute angle between axial direction.
Implement the embodiment of the present invention, there is following advantageous effect：
Steel core copper stranded conductor provided by the invention is grounded web frame, is made of the copper stranded conductor and internal steel strand wires of outer layer, this hair
The bright kelvin effect that high current is utilized, internal layer are made of low-cost steel strand wires, and it acts as support external copper
Twisted wire expands the outer ring of encirclement area of copper stranded conductor, only discharges the electric current of fraction；And exterior material is using copper stranded conductor as releasing
The medium of electric current has splendid corrosion resistance, avoids periodic maintenance cost；And have and good flow conductivity
Can, it can be very good leakage current.
In addition, since copper stranded conductor and steel strand wires are curve forms, the two has preferable flexibility, and tensile property is good,
It can be broken to avoid caused by settlement of foundation and external force.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is the Facad structure signal in a kind of one embodiment of steel core copper stranded conductor ground connection web frame provided by the invention
Figure；
Fig. 2 is the schematic cross-section of Fig. 1.
Specific implementation mode
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground describes.
As shown in Figure 1, showing in a kind of one embodiment of steel core copper stranded conductor ground connection web frame provided by the invention
Positive structure schematic；Referring also to shown in Fig. 2.In the present embodiment, the steel core copper stranded conductor ground connection web frame includes：
The steel strand wires 1 of internal layer are set to, and are set to the copper stranded conductor 2 of outer layer.
Wherein, the steel strand wires 1 include the steel conducting wire that multiply is mutually wound.1 shape of steel strand wires for being set to internal layer
At shaping material, 2 uniform fold of copper stranded conductor of the outer layer is simultaneously wrapped in 1 outside of steel strand wires.
Wherein, the copper stranded conductor 2 of the outer layer includes the copper wires that multiply is arranged side by side, and the multiply copper wires are with one
Fixed angle is wrapped circumferentially around on the periphery of steel strand wires 1.In one embodiment, it the angle ranging from the acute angle between axial direction.
It is understood that wherein, steel strand wires 1 play sizing supporting role, copper stranded conductor 2 can be strutted and only let out
Put the effect of fraction electric current.And copper stranded conductor 2 plays the role of most of electric current of releasing.
Simultaneously as the steel strand wires 1 of internal layer and the copper stranded conductor 2 of outer layer are whole in flexuosity, therefore in practical applications,
It has preferably flexible ability in the longitudinal direction, i.e. tensile capacity is very good, though be in the presence of settlement of foundation when
The performance of grounded screen is not interfered with.
Implement the embodiment of the present invention, there is following advantageous effect：
Steel core copper stranded conductor provided by the invention is grounded web frame, is made of the copper stranded conductor and internal steel strand wires of outer layer, this hair
The bright kelvin effect that high current is utilized（Most of electric current is flowed through from outer surface）, internal layer is by low-cost steel strand wires group
At it acts as the copper stranded conductors for supporting outside, expand the outer ring of encirclement area of copper stranded conductor, only discharge the electric current of fraction；And
Exterior material uses medium of the copper stranded conductor as leakage current, has splendid corrosion resistance, avoids periodic maintenance
Cost；And have and good guide performance, it can be very good leakage current.
In addition, since copper stranded conductor and steel strand wires are curve forms, the two has preferable flexibility, and tensile property is good,
It can be broken to avoid caused by settlement of foundation and external force.
It is above disclosed to be only a preferred embodiment of the present invention, the power of the present invention cannot be limited with this certainly
Sharp range, therefore equivalent changes made in accordance with the claims of the present invention, are still within the scope of the present invention.
