The flexible mineral fire-proof photoelectric composite cable additionally has an optical cable signal transmission function based on a fire-proof cable and is internally provided with the multimode fibers as temperature sensors; the latest DTS is applied for real-time monitoring of the internal temperature of the cable; a fire risk caused by the cable can be eliminated; the special cable has a certain intelligent application basis.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of flexible mineral fireproofing photoelectric composite rope.
Background technology
No matter be that the fail safe of electric wiring is most important in factory or building.According to national departments concerned statistics, the fire caused due to electric wiring in fire cause accounts for about 70%.And cable is the main body in electric wiring, it is again the link being difficult to carry out fire protection.Miscellaneous fire-resistant, fireproof cable in the market, all only there is the ability of " fire-resistant ", effectively can not monitor the ambient temperature of self, also cannot prevent and stop the generation of fire in advance, this brings great restriction to the application of this type of cable.How on the basis of cable fire function, increasing the fire preventing function of cable, is the direction that these those skilled in the art make great efforts.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of flexible mineral fireproofing photoelectric composite rope, it does not singly have fire-resistant performance, real time environment temperature monitoring can also be made to become possibility simultaneously, can effectively fire preventing occur.
A kind of technical scheme realizing above-mentioned purpose is:
A kind of flexible mineral fireproofing photoelectric composite rope, comprises the oversheath of radial coaxial setting successively from outside to inside, band and layer mineral, and is arranged in described layer mineral at least one cable and at least one optical cable, wherein:
Above-mentioned optical cable comprises gapless stainless steel tube, and is wrapped in the optical fiber of described gapless stainless steel tube radially inner side; Wherein have at least one optical cable, its gapless stainless steel tube radially inner side wraps up the core multimode fiber and at least one core monomode fiber that kink together.
The waterproof insulating layer that above-mentioned cable is set gradually from outside to inside by radial direction, mica belt and conductor bundle form.Above-mentioned conductor bundle is the tow of copper free wire.Above-mentioned layer mineral uses compound potter's clay mineral powder to fill.The material of the waterproof insulating layer of above-mentioned cable is crosslinked polyethylene.Above-mentioned band material is glass tape.Above-mentioned jacket material is fire retardant polyolefin.
The excircle of the stainless steel tube of above-mentioned optical cable is wound with mica tape.
Above-mentioned cable and optical cable are circumferentially alternately arranged successively in above-mentioned layer mineral.
The technical scheme of a kind of flexible mineral fireproofing photoelectric composite rope of the present invention, namely optical cable is added in the inside of flexible mineral fireproof cable, optical cable internal package optical fiber, wherein at least one optical cable internal package kinks a core multimode fiber together and at least one core monomode fiber, its technique effect makes fire prevention cable have the function of Signal transmissions concurrently transmitting electricity while, especially multimode optical cable can be connected with DTS temperature monitoring system, the ambient temperature of Real-Time Monitoring cable is made to become possibility, cable is made to obtain the function of initiatively fire preventing, there is certain intelligent Application basis.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of flexible mineral fireproofing photoelectric composite rope of the present invention;
Embodiment
In order to understand technical scheme of the present invention better, be described in detail by reference to the accompanying drawings below by embodiment particularly:
A kind of flexible mineral fireproofing photoelectric composite rope of the present invention, comprise the radial coaxial oversheath 1, band 3 and the layer mineral 2 that arrange and be arranged in the multimode optical cable 40 that layer mineral 2 multi-cable 5 and Duo Gen optical cable 4, wherein optical cable 4 have wrapped up thermometric successively from outside to inside, and monomode fiber 41.Layer mineral 2 carries out filling with the inorganic mineral powder that can sinter at 950 DEG C.
Optical cable is arranged in layer mineral 2 two large benefits: one is the temperature of optical fiber is exactly the temperature of cable inner, just in time may be used for DTS temperature monitoring; But optical cable is equivalent to embedded in cable, cable portion is subject to External Force Acting hardly, can effectively reduce fiber stress impaired.
Cable 5 is by conductor bundle 51, and mica belt 52 and waterproof insulating layer 50 form, and conductor bundle 51 is oxygen-free copper tow, is wrapped up by mica belt 52, and mica belt 52 plays heat insulation effect.Mica belt 52 outer wrapping waterproof insulating layer 50, and the material of waterproof insulating layer is crosslinked polyethylene.
The structure of optical cable 4 is the form of gapless stainless steel tube parcel optical fiber.What wrap up in the gapless stainless steel tube of optical cable 4 is multimode fiber 40 and monomode fiber 41, and the gapless stainless steel tube outside of optical cable 4 is wound around mica tape 42 and plays heat insulation effect.Single mode 41 optical fiber is used to provide the Signal transmissions of equipment.Multimode fiber 40 is connected with DTS temperature monitoring system, is used by multimode fiber 40 itself, be used to provide temperature monitoring and the fire-fighting early warning of cable entirety as temperature sensor.Gapless stainless steel tube can stop flame to directly act on optical fiber, and simultaneously gapless stainless steel tube also has the fast feature of heat transfer, is convenient to the temperature monitoring that multimode temperature-measuring optical fiber and DTS system carry out cable.High-temperature resistant optical fiber makes cable optical fiber under 950 DEG C of flame conditions also can keep normal work 3 hours.When temperature anomaly or breaking out of fire appear in cable part, the DTS main frame connected by multimode optical cable can thermometric alarm failure position, allows user make counter-measure in time, makes cable be provided with certain intelligentized basis.
Cable and be provided with described layer mineral 2 between optical cable and oversheath 1, relies on band 3 to be fixed.Layer mineral 2 uses magnesium hydroxide to fill for mineral powder.The material of band 3 is glass tape.The material of oversheath 3 is fire retardant polyolefin.
Layer mineral fire compartment wall has been made owing to have employed composite ceramic soil material, under Fire Conditions, the conductor wire core of cable and optical fiber can work in, fireproof porcelain tube heat insulation having of being formed by layer mineral safely, make cable of the present invention under load 1000V condition of work, still can bear burning in 950 DEG C, three hours, optical fiber does not rupture simultaneously, can keep normal work.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
