Description
Technical field
The utility model relates to a kind of cable, the copper alloy contact wire of particularly a kind of electric railway.
Background technology
Along with the develop rapidly of Chinese national economy, the continuous speed-raising of electric railway, more and more higher to the requirement of electric locomotive contact wire material, not only require that contact wire has good electric conductivity, to meet the big current load of electric express locomotive, and requiring that it has higher tensile strength, stronger material hardness and the mechanical performance such as high temperature resistant, wear-resistant, to ensure speed and the safety of train operation.China's high-speed electric railway copper alloy wire material used is mainly from developed country's imports such as Germany, Sweden, Japan.Because fine copper wire stretch-proof intensity is lower, hot mastication poor-performing, in order to improving SNR people become to assign to increase mechanical strength and the resistance to wear of copper alloys by adding silver, tin, magnesium etc., wherein, and copper silver contact wire, better, but intensity is little for electric conductivity; Cu-Sn contact wire, tensile strength is higher than copper silver contact wire, but conductivity is low; Copper magnesium alloy contact wire tensile strength is at present higher than Cu-Sn contact wire, but corrosion resistance is inadequate again.Therefore the characteristic of comprehensive above Prospect of Contact Wire Materials for Electrical Railway, is necessary design one, existing high conductivity at present, not only has high tensile strength and but also the novel Prospect of Contact Wire Materials for Electrical Railway of environmental corrosion resisting.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high conductivity, high-tensile, wear-resistant, environmental corrosion resisting, ensures the Graphene copper alloy contact wire of the electric railway of electrification railway contact net safety.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of Graphene copper alloy contact wire of electric railway, comprise contact wire line body, the cross section of described contact wire line body is Pear-Shaped, and described contact wire line body is Graphene copper alloy conductor.
Longitudinal head of contact wire line body described in the utility model is provided with identification groove.
The utility model compared with prior art, adopt the copper alloy conductor of graphene-containing, while guarantee high conductivity, its tensile strength strengthens and resistance to wear improves, corrosion resistance under severe atmospheric environment have also been obtained raising, can further improve circuit life-span and high ferro reliability of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in Figure 1, the Graphene copper alloy contact wire of the utility model electric railway, comprise contact wire line body 1, wherein, the cross section of contact wire line body 1 is Pear-Shaped, Pear-Shaped cross section is adopted first to be shape style and the physical dimension (TBT 2809-2005) that national standard has regulation contact wire, secondly, the object that contact wire makes Pear-Shaped is the side grooves of contact wire is for ease of installing contact wire wire clamp, make it in high ferro high-speed cruising process, contact wire bottom surface and pantograph arc contact surface are fitted more.Contact wire line body 1 is Graphene copper alloy conductor.Meanwhile, longitudinal head of contact wire line body 1 is provided with and identifies groove 2.
The utility model takes full advantage of the outstanding mechanical and physical performance of Graphene and Anticorrosive Character and graphene nano level material and has the features such as surface activity state, as the packing material of copper alloy contact wire, its resistance to stress ability and resistance to wear are increased, the intensity of basic material is strengthened along with the raising of resistance to stress ability after interpolation Graphene.Graphene also has very high conductive characteristic, and its specific insulation only has an appointment 10
-6Ω cm, can not affect the electric conductivity of copper alloy after interpolation.
The utility model can adopt advanced continuous up-casting continuous extruding technology technology, evenly hybrid nanoscale graphene powder is added under copper alloy molten condition, the adding proportion of nanoscale graphite alkene powder is between 0.2% ~ 1%, produce the copper alloy contact wire of superfine grained structure, i.e. Graphene copper alloy conductor.After adding Graphene, its tensile strength and resistance to wear are further improved, excellent performance.While guarantee high conductivity, not only tensile strength strengthens and resistance to wear raising, and the corrosion resistance under severe atmospheric environment have also been obtained raising, can further improve circuit life-span and high ferro reliability of operation and fail safe.
