Abstract
The utility model relates to a multifunctional cable with functions of communication and temperature monitoring, comprising a conductor, an insulating sheath, a metal sheath and an outer sheath, wherein the conductor, the insulating layer, the metal sheath and the outer sheath are arranged from inner side to outer side in order, and also comprising a temperature measuring optical cable and a communication optical cable, wherein the temperature measuring optical cable and the communication optical cable are arranged inside the insulating layer. Compared with the prior art, the multifunctional cable with functions of communication and temperature monitoring has the advantages of satisfying the demand of communication and temperature measuring, and simultaneously satisfying the demand of laying the temperature measuring optical cable at special zone such as rack pipe where the temperature measuring optical cable is difficult to lay secondarily.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of multi-functional cable with communication and temperature monitoring.
Background technology
Because cable line is owing to the needs of reliability, with the cable installation connection now.Consider on-line monitoring of cable monitoring cable temperature at any time simultaneously, find fault, a lot of cable installation temperature monitoring optical cables.And lay communication cable and on-line monitoring temperature optical cable, can increase additional workload.Some special laying under the environment, during like seabed and directly buried installation, communication cable and on-line monitoring temperature optical cable are difficult to lay simultaneously.
Lay again after present most of cable communication line and temperature measuring optical cable are cable laying, so both increased workload, influenced project progress again.If can develop a kind of cable, then can address the above problem with thermometric and communication function.
The utility model content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of multi-functional cable with communication and temperature monitoring to be provided.
The purpose of the utility model can realize through following technical scheme:
A kind of multi-functional cable with communication and temperature monitoring; Comprise conductor, insulating barrier, metallic sheath, oversheath; Described conductor, insulating barrier, metallic sheath, oversheath set gradually from the inside to surface; It is characterized in that also comprise temperature measuring optical cable, communication cable, described temperature measuring optical cable, communication cable are located in the insulating barrier.
Described temperature measuring optical cable, communication cable are two, and wherein one as subsequent use.
Compared with prior art, the utlity model has following advantage:
1, when producing, temperature measuring optical cable and communication cable are put into cable insulation; After laying the completion cable like this; Only need drawn connection with corresponding optical cable, just can satisfy communication and thermometric requirement, have also satisfied simultaneously in special location is laid like comb, to be difficult to the requirement that secondary lays temperature measuring optical cable;
2, place 1 reserve cable, in order to avoid can't repair after damaging.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Existing consider communication cable and on-line temperature monitoring optical cable and high-tension cable are merged, this kind optical cable can satisfy the power supply needs, can satisfy communication and on-line temperature monitoring needs again.As shown in Figure 1; Concrete structure comprises conductor 1, insulating barrier 2, metallic sheath 3, oversheath 4, temperature measuring optical cable 5, communication cable 6; Described conductor 1, insulating barrier 2, metallic sheath 3, oversheath 4 set gradually from the inside to surface, and described temperature measuring optical cable 5, communication cable 6 are located in the insulating barrier.Described temperature measuring optical cable 5, communication cable 6 are two, and wherein one as subsequent use.
Because the needs of the city appearance of the city and environment, domestic each big city are all making great efforts to improve the underground cable rate, when making the city more attractive in appearance, also strengthen the reliability of sending electricity.Along with the continuous lifting of urban construction up-to-dateness and the fast development of economic construction, the electric pressure of cable is also improving constantly.Quantity and the importance of cable line in electrical network is increasingly high, and the operational management of power cable, monitoring become more and more important.
Prevent that cable fire from being the importance that guarantees the operation of electric power system economic security.Because receive the constraint of urban planning and investment, common design is in cable tunnel or raceway groove, to lay some loops.And this design has tangible fragility when obtaining good maintainability, draws the utility model fire in case certain root cable fault worsens, and possibly bring disaster to cable and building structure on every side rapidly, causes all circuit paralysis in this pipeline.Underground ultrahigh-voltage XLPE cable work involves great expense, and in the tens million of units of every km, fire can cause great direct property loss, and repairing efficiency is long usually.
The power cable operating temperature is the very important factor of its current capacity of restriction in addition.The type selecting of power cable with lay the stage; Basically all carry out according to standard ambient temperature; The result who does like this is owing to can not comprehensively consider actual motion environment and ambient temperature; To cause cable when ambient temperature is high, to run on superheat state, reduce the service life of cable.So, monitor through operating temperature cable, can guarantee that cable system reaches best and safest current capacity.
The cable temp measuring system is mainly used in the security monitoring of the cable of the underground superhigh pressure in city with strategic importance.In distribution type fiber-optic cable temperature monitoring system; Along every cable laying detection optical fiber; Analyzing and processing through systems soft ware; Just can realize following two functions: 1. cable abnormity point early warning: through following the tracks of the slight change of the temperature of every bit on the cable overall length, find the early stage sign of fault, incipient fault is controlled in early days; 2. optimize the power transmission and distribution data and instruct power expansion: according to the temperature information of the high-tension cable every bit that obtains; The real-time thermal model of the cable of employing standard (like IEc60287) can obtain the situation of the dynamic current-carrying capacity of cable; And then can under the prerequisite of the load safety that guarantees cable, improve the utilance of these expensive assets.
