Embodiment
As shown in Figure 1, a kind of high purity carbon fiberreinforced aluminium alloy high pressure compound cable for measuring temperature, its core comprises many stranded aluminium alloy conductors 1, conductor shield 2, crosslinked polyetylene insulated layer 3, insulation screen 4, waterstop lapping layers 9; Core is coated with wrinkle aluminium alloy protecting jacket layer 6, PVC sheath layer 7, graphite semi-conductive layer 8 outward successively, and described wrinkle aluminium alloy protecting jacket layer 6 welds with core.
Flame retardant 10 is filled in space between described aluminium alloy conductor 1 and conductor shield 2, a fibre reinforced core 11 is provided with in described flame retardant 10, described fibre reinforced core 11 comprises carbon fiber wire and ceramic fibre silk, after the carbon fiber wire and ceramic fibre skein silk that become stock are closed, adopt resin-dipping, then adopt curing oven to form.In the present embodiment, described carbon fiber wire is one, and described ceramic fibre silk is the six roots of sensation.
A light unit 5 is also provided with in described flame retardant 10, as shown in Figure 2, described light unit 5 comprises multifiber 51 and the Loose tube 52 set gradually from inside to outside, non-metal reinforced layer 53 and sheath 54, Loose tube 52 is enclosed within outside optical fiber 51, full dry type water-blocking material 55 is filled in Loose tube 52, be provided with many equally distributed water blocking yarns 56 in non-metal reinforced layer 53, be embedded with between non-metal reinforced layer 53 and sheath 54 and tear rope 57; At least one optical fiber is inscribe the grating fibers having thermometric grating, and grating fibers forms a grating point for measuring temperature at interval of predetermined distance, and predetermined distance is 300-500 rice.
The present invention adopts the method directly making imprinting grating on optical fiber to carry out the manufacture of thermometric conductor.Be the light sensitivity utilizing fiber optic materials with the grating fibers that optical fiber imprinting becomes, by special processing mode, make to form space phase grating in fibre core, be partially formed the mirror surface of an arrowband, reflection is formed to the light of specific wavelength.When the temperature of optical fiber changes, the surrounding of grating can change along with expanding with heat and contract with cold of optical fiber, and this change can change reflection wavelength, by measuring the wavelength change of reverberation, just can measure the optical fiber temperature sensor of grating present position.Equally, by measuring the delay of reverberation, the position of grating can be learnt.Here it is utilizes the principle of grating fibers thermometric.
Direct quarter, the mode of grating did not produce supplementary load loss, and can not affect measuring distance, this production method is better than the production method of welding.The grating fibers thermometric mode become by optical fiber imprinting is owing to being special optical fiber targetedly, and reflected signal is strong, therefore requires all lower than Raman reflection thermometric mode to the transmitting power of equipment and receiving sensitivity, and the good stability of equipment.The benefit simultaneously brought is far measuring distance, and measuring distance can at more than 100km, and certainty of measurement is within ± 2 DEG C.
At least one optical fiber in these optical fiber carries out inscription grating, carries out inscription grating, by the temperature sensor of utilizing emitted light signal measurement diverse location grating in the position of setting.Here it is achieves and utilizes grating fibers thermometric.The present invention does not need the continuous temperature distribution of measuring whole piece circuit, every 300 ~ 500 meters of measurement points can be selected, or strengthen distribution optical grating point in sag minimum point, select the thermometric mode monitoring circuit variations in temperature of grating fibers, defeated biography capacity can be adjusted by the temperature grasped at any time.Preferably, 300 meters, 400 meters, the 500 meters spacing distances as adjacent point for measuring temperature can be selected.
According to a specific embodiment of the present invention, light unit inside is installed with 24 optical fiber, and 8 optical fiber in these 24 optical fiber carry out inscription grating.All imprinting 15 gratings on every root in these 8 optical fiber, i.e. totally 15 points for measuring temperature on every root.In this embodiment, use 16 optical fiber in 24 optical fiber to carry out communication, utilize 8 imprintings in 24 optical fiber to have the optical fiber of grating to carry out thermometric.Facts have proved, the method can reach good effect.
As used cable of the present invention in actual production, both can normal transmission of electric energy, can communication be carried out again, self can also carry out temperature survey.Which offers a saving the equipment such as ADSL, the OPGW increased in order to power communication, also can reduce the accidents such as the thunderbolt caused because of OPGW and threaten.The GPS wire temperature measuring equipment of the use taked at present work very high cost can also be saved in addition, save huge cost.Using cable of the present invention as the circuit of transferring electric power time, staff directly can determine the actual bearer situation of circuit according to the line temperature measured.
