Embodiment
In order to understand the technical solution of the utility model better, be described in detail by reference to the accompanying drawings below by embodiment particularly:
A kind of flexible mineral fireproofing photoelectric composite rope temperature monitoring system of the present utility model, comprises a kind of flexible mineral fireproofing photoelectric composite rope and a kind of DTS temperature monitoring system.Above-mentioned flexible mineral fireproofing photoelectric composite rope comprises the radial coaxial oversheath 1, band 3 and the layer mineral 2 that arrange and be arranged in layer mineral 2 multi-cable 5 and Duo Gen optical cable, wherein optical cable 4 radially inner side have wrapped up the multimode optical cable 40 of 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.The multimode fiber 40 wrapped up in the gapless stainless steel tube of optical cable 4 and monomode fiber 41.Be wound around mica tape 42 in the gapless stainless steel tube outside of optical cable 4 and play heat insulation effect.Monomode fiber 41 is used to provide device signal transmission, and multimode optical cable 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 layer mineral 2 between optical cable and oversheath 1, relies on band 3 to be fixed.Layer mineral 2 uses compound potter's clay mineral powder to fill.The material of band 3 is glass tape.The material of oversheath 3 is fire retardant polyolefin.
Owing to have employed composite ceramic soil material powder filling mineral layer 2 as fire compartment wall, under Fire Conditions, cable and optical cable can being sintered by layer mineral 2, having of being formed be heat insulation, work safely in fireproof porcelain tube, make a kind of flexible mineral fireproofing photoelectric composite rope under load 1000V condition of work, still can bear burning in 950 DEG C, three hours, optical cable does not rupture simultaneously, can keep normal work.
A kind of flexible mineral fireproofing photoelectric composite rope temperature monitoring system of the present utility model applies up-to-date distributed optical fiber temperature monitoring system DTS Real-Time Monitoring cable inner temperature, utilize the multimode optical cable of flexible mineral fireproofing photoelectric composite rope inside as temperature sensor, can play fire-fighting forewarning function to whole cable, be a kind of can elimination by the system possessing certain intelligent Application basis of cable institute initiation fire risk own.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
