Abstract
The utility model provides a railway photoelectricity is synthesized cable, it includes optical unit, electric unit and outer protective layer, optical unit include by interior and outer fibre core, adhesive linkage, foaming buffer layer, the outer jacket that sets up, electric unit including shielding four-wire set, signal line, electric unit still include by interior to outer cladding in proper order the shielding four-wire set and the insulating layer in the signal line outside, metal covering sheath, armor, the outer protective layer cladding in optical unit with electric unit's the outside. Therefore, the optical unit is used as an information channel in the distributed optical fiber sensing positioning system, has the characteristics of high sensitivity and capability of quickly and accurately responding to the change of an external space physical field, and greatly improves the precision and distance of monitoring and positioning. In addition, because the photoelectric composite cable simultaneously comprises the optical unit and the electric unit, the secondary repeated laying of the traditional optical cable and the traditional electric cable is avoided, and the optical unit has a certain monitoring effect on the electric unit.
Description
Technical field
The utility model relates to a kind of railway photoelectric comprehensive cable.
Background technology
In the prior art; the photoelectric comprehensive digital signal cable of using in the railway system is made up of light unit, electric unit, metallic sheath and external protection usually, and the effect of light unit and electric unit is exactly for TDCS and disperses self-discipline dispatching concentration system transmissions signal, data and electric power.Can only guarantee railway operation in the existing railway system, when running into fault or having potential safety hazard, can't accomplish monitoring, still not accomplish informationization, still need the cooperation of manpower the potential safety hazard of railway.Can cause whole system function to descend in case go wrong, even paralysis.
In order to address the above problem, the distributing optical fiber sensing navigation system can be used in adverse circumstances safely and effectively, solved the technical barrier that many industries exist for many years always, has the very big market demand, for example the monitoring of the railway monitoring of railway and fault location, environmental monitoring, communication line and fault location, the monitoring of building structure (bridge, culvert, tunnel etc.), the monitoring of sensitizing range.Original optoelectrical cable is the sandwich layer that light unit and electric unit is laid on cable, arranged outside at sandwich layer has armour and outer jacket etc., therefore when comprehensive cable is subjected to faint STRESS VARIATION, it is very faint to be laid on the STRESS VARIATION of the light unit of sandwich layer experiencing, so sensitivity is not high.
Summary of the invention
The purpose of this utility model provides a kind of railway photoelectric comprehensive cable with sensitivity preferably, and it can be the distributing optical fiber sensing navigation system monitor signal and transferring electric power are provided.
The utility model can be implemented by the following technical programs: a kind of railway photoelectric comprehensive cable; it comprises light unit, electric unit and external protection; described smooth unit comprises fibre core, adhesive linkage, foamed damping layer, the outer jacket that from inside to outside is provided with; described electric unit comprises shielding quad, holding wire; described electric unit also comprises thermal insulation layer, metallic sheath sheath, the armour that is coated on the described shielding quad and the holding wire outside from inside to outside successively, and described external protection is coated on the outside of described smooth unit and described electric unit.
Described electric unit also comprises many holding wires.
Described electric unit also comprises the inner covering that is arranged between described metallic sheath sheath and the described armour.
Described shielding quad is by being followed successively by coat of metal, belting layer, insulated single wire group in outer the reaching.
Described insulated single wire group is by being followed successively by exodermis, foaming layer, endodermis, metal core in outer the reaching.
Compared with the prior art the utility model has following advantage: because the light unit of railway photoelectric comprehensive cable is arranged on the outside of electric unit, the light unit is as information channel in the distributing optical fiber sensing navigation system, have high sensitivity, to external world the variation of space physics field can make rapidly, the characteristics of accurate response, make monitoring locating accuracy and distance improve greatly.And,, avoided the secondary of traditional optical cable and cable to repeat to lay, and the light unit has the effect of certain monitoring to electric unit owing to comprise light unit and electric unit simultaneously in the optoelectrical cable.
