Embodiment 1

[0034] See figure 1 with figure 2 , figure 1 A schematic structural diagram of a smart strand for an electrorating railway contact network is drawn. As shown, a smart strand for an electrified railway contact network comprising a smart stranded body 1, the intelligent stranded body 1 is a monofilament with a multi-single wire. A single-core multilayer stranded wire, the peripheral monofilament including a copper alloy monofilament 4 and a carbon fiber composite monofilament 6, the central monofilament including the rubber material 3 and the optical fiber 2, the center of the rubber material 3 is set one Optical fiber 2, the optical fiber 2 is present in the core of the rubber material 3.

[0035] The surface of the copper alloy monofilament 4 has a preservative coating 5.

[0036] The optical fiber 2 is covered with the rubber material 3 by a heat squeeze.

[0037] The diameter of the peripheral monofilament is greater than the diameter of the peripheral monofilament.

[0038] The...

Embodiment 2

[0047] See figure 1 with image 3 , figure 1 A schematic structural diagram of a smart strand for an electrorating railway contact network is drawn. As shown, in fact, the peripheral monofilament includes two laps surrounding the center monofilament, wherein the inner ring of the inner ring close to the center monofilament is made of a copper alloy monofilament 4 and a carbon fiber composite material. Single wire 6 is uniformly spaced apart, and the outer ring of the outer ring away from the central monofilament is a copper alloy monofilament 4.

[0048] SeeFigure 4 The structures of the intelligent strand 1 include, but are not limited to Figure 4 The species shown, that is, 1 * 7, 1 * 19, 1 * 37, 1 * 7 * (1 + 6), 1 * 7 * (3 + 9), according to the actual use, copper with anti-corrosion coating 5 The alloy monofilament 4 and the carbon fiber composite monofilament 6 are distributed in any position of the strand.

Abstract

The invention relates to an intelligent stranded wire for a contact network of an electrified railway and a preparation method of the intelligent stranded wire. The intelligent stranded wire comprises an intelligent stranded wire body (1), wherein the intelligent stranded wire body (1) is a single-core multi-layer stranded wire formed by stranding a plurality of peripheral monofilaments around a central monofilament, the peripheral monofilaments comprise copper alloy monofilaments (4) and carbon fiber composite monofilaments (6), the central monofilament comprises a rubber material (3) and an optical fiber (2), and the optical fiber (2) is arranged in the center of the rubber material (3). The intelligent stranded wire has the advantages of high sensitivity, good stability, long test distance, simple structure and the like, realizes intelligent monitoring of the overhead line system, can remarkably improve the safety and reliability of the overhead line system of the high-speed electrified railway, reduces the labor intensity of manual line patrol, and greatly reduces operation and maintenance cost.

Description

Technical field [0001] The present invention relates to the technical field of electrified railway contact network, and more particularly to an intelligent strand for an electrified railway contact network and a preparation method thereof. Background technique [0002] The domestic electrified railway contact network has an overhead manner, and the stranded dual role is a dual role in which the contact line is suspended and the power locomotive is indispensable. It is an indispensable part in the contact network, and its structure is the same as the same diameter copper alloy line through the strand Comparable. Because of the diversity of the service environment, the intersection of the spatial structure, it is easy to cause damage to the shares under mechanical and electrical action. If the corresponding measures are not taken in time, the locomotive will be used to operate safety hazards. The environmental pollution causes the air quality of some cities to decrease, and the sur...
