Abstract
The utility model discloses a kind of railway electrification catenary, comprise catenary body, described catenary adopts total number of share of stock/copper covered steel number of share of stock to be the twisted wire of 19/7, described copper clad steel wire is 7 strands, be put in the nexine of twisted wire, alloyed copper wire is 12 strands, is put in the skin of twisted wire.The have the following advantages structure of this railway electrification catenary of catenary of the present utility model be twisted wire skin is be that base material is at Surface coating one deck oxygen-free copper with alloyed copper, it has very high electric conductivity and high-frequency transmission performance, also can not erosion corrosion even if had again very high decay resistance and resistance to abrasion external copper layer to be worn; The internal layer of twisted wire is copper covered steel material, and the maximum intensity of copper covered steel is that intensity is high, also has the advantages such as good conductivity.
Description
Technical field
The utility model relates to electrified railway and urban rail transit contact network metal material field, specifically a kind of railway electrification China catenary.
Background technology
In recent years, the metallic material that catenary is used in China's electrified railway and urban track traffic contact wire mainly contains following several; Galvanized strand wires, aluminum-cladding stranded wire (or aluminium bag aluminum-steel hybrid twisted wire), full copper stranded conductor etc.Although wherein galvanized strand wires tensile strength is high, cheap, poor electric conductivity, increase contact system crushing and energy consumption, and resistance to corrosion difference and being eliminated gradually; Aluminum-cladding stranded wire or aluminium bag aluminum-steel hybrid twisted wire because of the mechanical strength of aluminium poor, under acid or alkaline environment, resistance to corrosion is poor, and makes contact system complex structure and other problems and affect its use for preventing from producing electrochemical corrosion between itself and copper contact wire; The electric conductivity of full copper stranded conductor is good, and corrosion stability is good, but its mechanical strength is poor, and during temperature traverse, relaxivity change greatly, and copper is expensive especially entirely, causes engineering cost high.
Utility model content
The purpose of this utility model overcomes catenary of the prior art to there is pulling strengrth, cost and corrosion resistance balance not in place, affect the use of Railway Electric, a kind of catenary combined with the intensity of the electric conductivity of copper and steel is provided, there is high conductivity, high strength, the catenary of highly corrosion resistant, to replace current full copper, constantan, the catenary product of copper covered steel.
The technical solution of the utility model is achieved in that a kind of railway electrification catenary, comprise catenary body, described catenary adopts total number of share of stock/copper covered steel number of share of stock to be the twisted wire of 19/7, described copper clad steel wire is 7 strands, be put in the nexine of twisted wire, alloyed copper wire is 12 strands, is put in the skin of twisted wire.
As preferably, the outer field alloyed copper wire of described twisted wire is take alloyed copper as inner substrate, at the coated one deck oxygen-free copper of substrate surface.With alloyed copper be base material at Surface coating one deck oxygen-free copper, it has very high electric conductivity and high-frequency transmission performance, also can not erosion corrosion even if had again very high decay resistance and resistance to abrasion external copper layer to be worn.
Compared with prior art, the have the following advantages structure of this railway electrification catenary of catenary of the present utility model is that twisted wire skin adopts copper-clad copper material, copper-clad copper material is that base material is at Surface coating one deck oxygen-free copper with alloyed copper, it has very high electric conductivity and high-frequency transmission performance, also can not erosion corrosion even if had again very high decay resistance and resistance to abrasion external copper layer to be worn; The internal layer of twisted wire is copper covered steel material, and the maximum intensity of copper covered steel is that intensity is high, also has the advantages such as good conductivity.Electrified its advantage of catenary of novel railway and copper covered steel catenary, aluminium Baogang catenary is compared and is had good resistance to corrosion, resistance to abrasion and electric conductivity, the advantages such as long service life.Can provide full copper inaccessiable intensity with full copper this catenary of comparing with constantan, light specific gravity, the advantages such as engineering cost is low.

Detailed description of the invention
Detailed description of the invention of the present utility model is as follows:
Embodiment: as shown in Figure 1: a kind of railway electrification catenary, comprises catenary body, described catenary adopts total number of share of stock/copper covered steel number of share of stock to be the twisted wire of 19/7, described copper clad steel wire 1 is 7 strands, be put in the nexine of twisted wire, alloyed copper wire 2 is 12 strands, is put in the skin of twisted wire.The outer field alloyed copper wire of described twisted wire is with alloyed copper first 2.1 for inner substrate, at the coated one deck oxygen-free copper-wire 2.1 of substrate surface.
The have the following advantages structure of this railway electrification catenary of above-mentioned catenary is that twisted wire skin adopts copper-clad copper material, copper-clad copper material is that base material is at Surface coating one deck oxygen-free copper with alloyed copper, it has very high electric conductivity and high-frequency transmission performance, also can not erosion corrosion even if had again very high decay resistance and resistance to abrasion external copper layer to be worn; The internal layer of twisted wire is copper covered steel material, and the maximum intensity of copper covered steel is that intensity is high, also has the advantages such as good conductivity.Electrified its advantage of catenary of novel railway and copper covered steel catenary, aluminium Baogang catenary is compared and is had good resistance to corrosion, resistance to abrasion and electric conductivity, the advantages such as long service life.Can provide full copper inaccessiable intensity with full copper this catenary of comparing with constantan, light specific gravity, the advantages such as engineering cost is low.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to above-described embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive from content disclosed in the utility model or associate, all should think protection domain of the present utility model.
