Abstract
The utility model relates to a high -speed railway is with contact cable of area control includes optical fiber unit, carbon fiber complex core, alloy -layer by interior outside to in proper order, the transposition of optical fiber unit and carbon fiber complex core is in the same place, the alloy -layer presses the cladding press packed bale to wrap up in on optical fiber unit and carbon fiber complex core through pricking, both sides symmetrical arrangement is fluted about the alloy -layer. The utility model discloses solved the problem that the optical fiber unit diameter is little, intensity is low well, the operation conditions of ability on -line monitoring wire under different situation, through the regulation, ability furthest's performance wire transmittability.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, the contact cable taking of particularly a kind of band monitoring used for high-speed railway.
Background technology
Along with railway significantly raises speed, increasing the weight of and competition of operations task, Heavy-Haul Railway, high speed have become the development trend of world's railway systems, and the contact wire used in railway operation is one of critical equipment of wheel-track type railway high speed.Fine copper used at present and Kufil contact wire intensity are only 350-400MPa, are suitable only for middle low speed railway, are difficult to the service condition meeting high-speed railway.
Domestic and international existing in the contact wire of low speed railway, generally adopt continuous up-casting, coordinate cold-work strengthening, make its intensity can reach the requirement of railway operation.Material composition is mainly that main centre adds wire-core with fine copper, Kufil, signal bronze and copper magnesium alloy etc., strong in order to the stretching improving contact cable taking.The technological method for processing of this kind of basic cable is simply efficient, but its fatal weakness to be material structure fine and close not, cable deadweight is comparatively large, seriously sagging after cable erection, and cable metaplasia in drawing process is thorough, and core structure crystal grain is thicker; And updraft continuous casting process is used for producing simple alloy mostly, for complex alloys, continuous up-casting is difficult to carry out, and therefore defect is a lot.Along with railway high speedization is run, simple cold-work strengthening cannot meet its requirement.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of contact cable taking of band monitoring used for high-speed railway.
Technical solution of the present utility model: a kind of contact cable taking of band monitoring used for high-speed railway, comprises, fiber unit, carbon fiber complex core, alloy-layer from inside to outside successively; Described fiber unit and carbon fiber complex core twist together; Described alloy-layer is wrapped on fiber unit and carbon fiber complex core by pressure coating machine; Described alloy-layer the right and left is arranged symmetrically with fluted.
Further, the material of described alloy-layer is aluminium alloy.
beneficial effect:
Compared with prior art; the contact cable taking of band monitoring used for high-speed railway of the present utility model; due to the advantage that carbon fibre material is intrinsic; this contact cable taking is compared with the ACSR cable of same diameter; the weight of cable obtains and significantly alleviates; double current-carrying capacity can be provided, effectively solve cable sagging problem; Can work at higher temperatures, reach as high as 200 degrees Celsius; Core can be anticorrosive, and do not have etching problem between bimetallic; Because can provide higher current-carrying capacity, so also effectively reduce engineering cost simultaneously, can hold the conductor of 28% compared with same diameter traditional cable, high strength core can effectively reduce cable rack quantity more, or reduces the height of cable rack; Effective minimizing cable is sagging, makes ground biology safer.。
accompanying drawing illustrates:
Fig. 1 is structure chart of the present utility model;
In figure, 1-fiber unit, 2-carbon fiber complex core, 3-alloy-layer, 4-groove.
Embodiment
As shown in Figure 1, the contact cable taking of a kind of band monitoring used for high-speed railway of the present utility model, comprises, fiber unit 1, carbon fiber complex core 2, alloy-layer 3 from inside to outside successively; Described fiber unit 1 and carbon fiber complex core 2 twist together; Described alloy-layer 3 is wrapped on fiber unit 1 and carbon fiber complex core 2 by pressure coating machine; Described alloy-layer 3 the right and left is arranged symmetrically with fluted 4.
Wherein, the material of described alloy-layer 3 is aluminium alloy.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
Claims (2)
