Fig. 2 is the structural representation of stainless steel light of the present invention unit.
Embodiment
As shown in Figure 1, a kind of flexible insulation is from cable for measuring temperature, comprise four conductor wire cores, at described four conductor wire cores, be coated with successively insulation lining 5, metallic sheath 6 and non metallic sheath 7 outward, between described four conductor wire cores and insulation lining 5, be filled with magnesium oxide insulated filler 4; Described conductor wire core center is copper conductor 1, is coated with successively insulating barrier 2 and protective layer 3 outside described copper conductor 1; Also include stainless steel light unit 8, described stainless steel light unit 8 is contained in described magnesium oxide insulated filler 4.
As shown in Figure 2, stainless steel light unit 8 is for being placed in stainless steel protection pipe 9 interior composition by some optical fiber 12, and stainless steel protection pipe 9 adopts loose tube structures, and optical fiber 12 is played mechanical damping, prevents the lateral pressure of metal wire and play thermal insulation protection effect; In stainless steel protection pipe 9 spaces, fill continuously suitable water-blocking material 11, water-blocking material 11 can effectively prevent that moisture or moisture content from infiltering light unit, does not damage optical fiber 12 transmission characteristics and useful life; Stainless steel protection pipe 9 outer cladding layer of copper layers 10, effectively prevent the potential corrosion that different materials forms.Described stainless steel light unit 8 extends along described conductor wire core, and at least one optical fiber is for inscribing the grating fibers that has thermometric grating; On grating fibers, at interval of predetermined distance, form a grating point for measuring temperature, predetermined distance is 300-500 rice.
The present invention adopts the method for directly making imprinting grating on optical fiber to carry out the manufacture of thermometric conductor.With the grating fibers that optical fiber imprinting becomes, be the light sensitivity of utilizing fiber optic materials, by special processing mode, make to form space phase grating in fibre core, the local mirror surface that forms an arrowband, forms reflection 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 changes can change reflection wavelength, by measuring catoptrical wavelength change, just can measure the optical fiber temperature sensor of grating present position.Equally, by measuring catoptrical delay, the position that can learn grating.Here it is utilizes the principle of grating fibers thermometric.
The mode of directly carving grating does not produce supplementary load loss, can not affect measuring distance, and this production method is better than the production method of welding.The grating fibers thermometric mode becoming by optical fiber imprinting is owing to being special optical fiber targetedly, and reflected signal is strong, therefore the transmitting power of equipment and receiving sensitivity are required all lower than Raman, to reflect thermometric mode, and the good stability of equipment.The benefit of simultaneously bringing is far measuring distance, and measuring distance can be more than 100km, and certainty of measurement is in ± 2 ℃.
On at least one optical fiber in these optical fiber, inscribe grating, in the position of setting, inscribe grating, by the temperature sensor of utilizing emitted light signal measurement diverse location grating.Here it is has realized and has utilized grating fibers thermometric.The present invention does not need the continuous temperature of measuring whole piece circuit to distribute, can select every 300～500 meters of measurement points, or strengthen distribution optical grating point in sag minimum point, and select the thermometric mode monitoring circuit variations in temperature of grating fibers, can by the temperature of grasping, adjust defeated biography capacity at any time.Preferably, can select 300 meters, 400 meters, the 500 meters spacing distances as adjacent point for measuring temperature.
According to a specific embodiment of the present invention, inside, stainless steel light unit is installed with 24 optical fiber, on 8 optical fiber in these 24 optical fiber, inscribes grating.15 gratings of imprinting all on every in these 8 optical fiber, i.e. totally 15 points for measuring temperature on every.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.
In actual production as use cable of the present invention, both normal transmission of electric energy, can carry out communication again, can also self carry out temperature survey.So just saved the equipment such as ADSL, OPGW that increase for power communication, also can reduce because the accidents such as the thunderbolt that OPGW causes threaten.Can also save in addition the very expensive GPS wire temperature measuring equipment of use of taking in current work, save huge cost.When the circuit using cable of the present invention as transferring electric power, staff can be according to the actual bearer situation that measures end line temperature and directly determine circuit.
