Abstract
The utility model discloses an intelligent cable for a subway. The cable comprises form interior to exterior in sequence: a copper conductor, a conductor shielding layer, a crosslinking polyethylene insulation layer, an insulation shielding layer, a copper wire shielding layer, a wrapping belt, a plastic-aluminum composite belt, a comprehensive waterproof layer, an armored copper belt, and a ratproof antproof ultraviolet-proof halogen-free low-smoke sheath, wherein the copper wire shielding layer is provided with two temperature measurement optical fibers and two communication optical fibers. According to the intelligent cable for subway, the temperature measurement optical fibers and the communication optical fibers are disposed in the copper wire shielding layer, so that the actual operation situation, the heat distribution, and the abnormality of the cable can be monitored in real time, and therefore the object of guard against gradual creeping is achieved, problems can be noticed and solved immediately before the cable and a power system is damaged, the service lives of the cable and the power system are prolonged, and power transferring and communication are achieved on one line, thus purchasing and laying costs are reduced.
Description
Technical field
The utility model relates to a kind of subway intelligent cable that urban track traffic electric power transfer is used that is applicable to.
Background technology
Government's official announcement, ended for the end of the year 2013, and China has 36 cities and gets permission to build city rail traffic route, and according to " planning of " 12 " overall transportation system ", by 2015, National urban orbit construction mileage will reach 3000 kilometers.Along with administrative examination and approval power and open infusion of financial resources among the people, urban track traffic will occur building tide in the recent period, the coming years, increase every year mileage 500 kilometers of left and right.In conjunction with current various places Construction of Urban Rail Traffic present situation, expect the year two thousand twenty, National urban track operation mileage will reach 6000 kilometers, and the investment aspect track traffic will reach 3-4 trillion yuan.Track traffic has that freight volume is large, speed is fast, low energy consumption, safety, on schedule, the feature such as protection of the environment, green low-carbon, energy savings and land used, play vital effect solving current Chinese each big city problem of blocking up.
Future, subway and the people's daily life is more and more closely bound up, the fail safe of subway is also just more and more important, if cable self energy Real-Time Monitoring operation conditions, there is temperaturing lifting abnormality energy and alarm, just can reduce the operation troubles of cable, can not cause the unexpected power-off of subway or control signal, thereby cause accident to occur, guarantee to make the punctual safe operation of subway, ensure that the people's lives and properties are without prejudice, in addition if can transmission communication information in transferring electric power, just can reduce the cost that again lays communication line.
Chinese patent literature CN201698824U disclosed " 35kV power cable for rail transit " and CN201655399U disclosed " power cable for rail transit ", although these two kinds of cable physical properties are pretty good, do not possess the function of intelligent temperature measurement or communication.
Utility model content
The purpose of this utility model is to provide a kind of security performance that can effectively improve circuit operation and useful life and transmission communication information can transferring electric power time, the subway intelligent cable that intelligent temperature measurement and photoelectricity transmission are integrated.
The technical scheme that realizes the utility model object is a kind of subway intelligent cable, sets gradually from the inside to the outside copper conductor, conductor shield, crosslinked polyetylene insulated layer, insulation screen, shielding layer of copper wires, twining package tape, aluminium-plastic tape, Comprehensive Preventing water layer, armouring copper strips and termite-resistant rodent-resistant antiultraviolet low smoke, zero halogen sheath; At described shielding layer of copper wires, two temperature-measuring optical fibers and two communication optical fibers are set.
Described two temperature-measuring optical fibers are symmetrical arranged; Described two communication optical fibers are symmetrical arranged.
The copper wire of described shielding layer of copper wires is put for dredging winding.
The longitudinal wrapped setting of described aluminium-plastic tape.
Adopt technique scheme, the utlity model has following beneficial effect: (1) cable of the present utility model is provided with temperature-measuring optical fiber and communication optical fiber in shielding layer of copper wires, thereby practical operation situation that can Real-Time Monitoring cable, monitoring cable heat distributes and is abnormal, check erroneous ideas at the outset to accomplishing in cable running, cable and electric power system destroyed before, just can pinpoint the problems and can deal with problems rapidly, improve the useful life of cable and electric power system, can accomplish transferring electric power and the communication simultaneously of a circuit, reduce buying and laid down cost simultaneously.
(2) cable of the present utility model arranges Comprehensive Preventing water layer, can improve cable block-water performance, and the dual anti-biological destruction structure of protection against rodents armour and termite-resistant rodent-resistant antiultraviolet sheath is set, and makes this product more can adapt to severe operational environment.
(3) shielding layer of copper wires of the present utility model adopts and dredges around copper wire, increases metallic shield cross section, improves cable short circuit current passage, improves cable security performance.Copper wire aspect ratio optical fiber is high, can provide peripheral mechanical protection for optical fiber.
(4) the longitudinal wrapped setting of aluminium-plastic tape of the present utility model, can improve the water resistance of cable.
(5) cable of the present utility model has low cigarette, Halogen, nontoxic, waterproof, weather-proof, high flame retardant, intelligent temperature measurement monitoring, the characteristic of the common transmission of communication and electric power, therefore can not only ensure that electric power supply system for subway is as fire, non-toxic and corrosive gas discharges, and the amount of being fuming is little, be beneficial to passenger evacuation, thereby guarantee the security of the lives and property of Metro Passenger, intelligent temperature measurement optical fiber in the product heat distribution of monitoring cable at any time simultaneously, concentrate if any abnormal heat, can be delivered to control and monitor console by Fiber Optical Communication System, can fast finding to abnormity point and process, can effectively extend cable life and reduce the failure rate of electric power system.
