Abstract
A cable with optical fibers therein, comprising: cable core, insulating layer and cable buffer layer from interior to exterior set gradually in the outside of cable core, and the embedded optic fibre that sets up of cable buffer layer outside the insulating layer, above-mentioned optic fibre are the heliciform winding or snakelike laying in the cable. The utility model discloses an in the cable that inside has optic fibre, with optic fibre embedded at the cable buffer layer, can effectively reduce various external factors in cable laying and the measurement process to temperature measurement optic fibre and measurement accuracy's influence, improve monitoring accuracy, still reduce the construction degree of difficulty in addition. The optical fiber is wound in the cable according to a certain proportion, and the optical fiber is not easy to break when the cable expands with heat and contracts with cold or is bent, so that the service life of the cable is prolonged, and the product reliability of the cable is improved.
Description
Technical field
The utility model relates to the technical field of cable, is that a kind of inside that can Measurement accuracy cable insulation temperature is with the cable of optical fiber specifically.
Background technology
Great-leap-forward development along with Chinese national economy, every profession and trade and the also sharp increase of residential electricity consumption demand, for bringing into play to greatest extent the power supply capacity of existing power cable, make the economic operation cost of power supply enterprise reach optimization, in the urgent need to grasping at any time power cable ruuning situation, to guaranteeing, under the prerequisite of power supply safety, farthest to excavate the power supply capacity of existing power cable.In addition, cable lay environment and there is very big-difference in mode, the temperature rise along the line of whole piece cable is different, the key that affects current-carrying capacity of cable is the temperature bottleneck of cable, finds and solve the ampacity that temperature bottleneck can improve whole piece cable greatly.Have the relevant report that distributed optical fiber temperature measurement technology is applied to cable temperature on-line monitoring both at home and abroad, but adopt is laid in by optical fiber the monitoring that cable surface carries out cable operating temperature more, not only difficulty of construction is large, and measurement data is subject to extraneous factor impact, affects certainty of measurement.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of inside that can Measurement accuracy cable insulation temperature with the cable of optical fiber.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
Inside of the present utility model is with the cable of optical fiber, comprise: cable core, insulating barrier and cable resilient coating, insulating barrier and cable resilient coating are successively set on the outside of cable core from the inside to the outside, the embedded optical fiber that arranges of cable resilient coating outside insulating barrier, above-mentioned optical fiber be wound around in the shape of a spiral or snake laying in cable.
The utility model can also adopt following technical measures:
Described optical fibre packages overlays in two waterstops.
When described optical fiber is wound around in the cable that is laid in the shape of a spiral, distance and the ratio between cable core diameter between adjacent two circle optical fiber are 1～1.5: 1.
Advantage and the good effect that the utlity model has are:
In the cable of inside of the present utility model with optical fiber, optical fiber is embedded in to cable resilient coating, can effectively reduces the impact of various extraneous factors on temperature-measuring optical fiber and certainty of measurement in cable laying and measuring process, improve monitoring accuracy, also reduce in addition difficulty of construction.Optical fiber is wrapped in cable according to a certain percentage, can guarantee that cable expands with heat and contract with cold or optical fiber frangibility not crooked time, thereby has extended the useful life of cable, has improved the product reliability of cable.
Accompanying drawing explanation
Fig. 1 is that inside of the present utility model is with the schematic diagram of the cable internal structure of optical fiber.
Embodiment
Referring to drawings and Examples, the utility model is described in detail.
Fig. 1 is that inside of the present utility model is with the schematic diagram of the cable internal structure of optical fiber.
As shown in Figure 1, inside of the present utility model is with the cable of optical fiber, comprise: cable core, insulating barrier 2 and cable resilient coating 3, insulating barrier and cable resilient coating are successively set on the outside of cable core from the inside to the outside, the embedded optical fiber 4 that arranges of cable resilient coating outside insulating barrier, above-mentioned optical fiber be wound around in the shape of a spiral or snake laying in cable.
Optical fibre packages overlays in two waterstops.
When optical fiber is wound around in the cable that is laid in the shape of a spiral, distance and the ratio between cable core diameter between adjacent two circle optical fiber are 1.2: 1.
In the cable of inside of the present utility model with optical fiber, optical fiber is embedded in to cable resilient coating, can effectively reduces the impact of various extraneous factors on temperature-measuring optical fiber and certainty of measurement in cable laying and measuring process, improve monitoring accuracy, also reduce in addition difficulty of construction.Optical fiber is wrapped in cable according to a certain percentage, can guarantee that cable expands with heat and contract with cold or optical fiber frangibility not crooked time, thereby has extended the useful life of cable, has improved the product reliability of cable.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model with preferred embodiment openly as above, yet any those skilled in the art, do not departing within the scope of technical solutions of the utility model, certainly can utilize the technology contents of announcement to make a little change or modification, become the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
