Abstract
The utility model relates to tinned copper-magnesium alloy stranded wire for an electrified railway contact net, which is characterized in that the stranded wire is formed by 17 metal wires (1); the outside of each metal wire is provided with a tinned layer (2); and the metal wires (1) are copper-magnesium alloy wires. For the tinned copper-magnesium alloy stranded wire for the electrified railway contact net, the tinned layer has good anti-oxidation capability so as to avoid the contact between the metal wire and the air, the copper-magnesium alloy wire has better antiseptic effect and strong conductivity, and the tinned stranded wire better solves the corrosion problem caused by the contact between the copper stranded wire and the aluminum conductor.
Description
(1) technical field
The utility model relates to a kind of electrification railway contact net tin-coated copper magnesium alloy strand.
(2) background technology
Continuous speed-raising along with electric railway and urban track traffic, requirement to contact line is more and more higher, not only require twisted wire to have advantages of higher tensile strength, and require it to have excellent conducting performance, to satisfy the big current load of electric express locomotive, to guarantee the speed and the safety of train operation.And the baffler that contacts with contact line uses aluminum products in a large number, when the copper twisted wire directly is connected with aluminium conductor, the contact-making surface of these two kinds of metals very easily forms electrolyte under the effect of water in air branch, carbon dioxide and other impurity, thereby what form is that negative pole, copper are anodal primary cell with aluminium, make aluminium produce couple corrosion, cause the contact resistance of copper, aluminium junction to increase.In addition,, be in operation after cold cycling (energising and outage) repeatedly, can make the contact point place produce bigger gap and influence contact, also increased contact resistance because the modulus of elasticity and the thermal coefficient of expansion of copper, aluminium differ greatly.The increase of contact resistance, the temperature that will cause in service raises.Corrosion oxidation will aggravate under the high temperature, produces vicious circle, and quality of connection is further worsened, and causes the contact point temperature too high even accident such as can smolder, burn at last, causes whole contact net system paralysis.According to railway systems regulations, be 30 years the useful life of twisted wire, therefore is necessary to design a kind of novel twisted wire that can the contact corrosion of fine solution copper aluminium, thereby guarantees railway contact line safety.
(3) summary of the invention
The purpose of this utility model is an etching problem in order to overcome copper contact wire and to contact with aluminium conductor, provides a kind of simple in structure, and small investment is easy to suitability for industrialized production, lower-cost electrification railway contact net tin-coated copper magnesium alloy strand.
The purpose of this utility model is achieved in that a kind of electrification railway contact net tin-coated copper magnesium alloy strand, it is characterized in that: described twisted wire is combined by 17 one metal wires, described every one metal wire is outside equipped with tin coating, and described wire is a Cu-Mg alloy wire.
The utility model electrification railway contact net with the beneficial effect of tin-coated copper magnesium alloy strand is:
1) tin coating has good anti-aging capability, the possibility that has stoped wire to contact with air, and Cu-Mg alloy wire has better antiseptic effect, and electric conductivity is strong.
2) zinc-plated twisted wire has well solved the copper twisted wire and has contacted the possibility that corrosion occurs with aluminium conductor.
(4) description of drawings
Fig. 1 is the utility model electrification railway contact net tin-coated copper magnesium alloy strand structural representation.
Among the figure:
Wire 1, tin coating 2.
(5) embodiment
Referring to Fig. 1, a kind of electrification railway contact net tin-coated copper magnesium alloy strand that the utility model relates to, described twisted wire is combined by 17 one metal wires 1, and described every one metal wire 1 is outside equipped with tin coating 2, and described wire 1 is a Cu-Mg alloy wire.
During making, the copper magnesium alloy that pulls into monofilament is advanced electrolysis tank carry out zinc-plated processing, the copper magnesium alloy that will reach the tin coating thickness requirement then advances stranding machine and carries out stranded processing, makes zinc-plated twisted wire finished product.
