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.
Communication cable and on-line temperature monitoring optical cable and carbon fiber are merged, and this kind thermometric carbon fiber photoelectricity composite 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 carbon fiber compound wire core 1, insulating barrier 2, metallic sheath 3, oversheath 4, temperature measuring optical cable 5, communication cable 6; Described carbon fiber compound wire core 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 2.Described temperature measuring optical cable 5, communication cable 6 are two, and wherein one as subsequent use.Said carbon fiber compound wire core 1 by epoxy resin, expansion multiple at the nano expanded graphite more than 100 times with strengthen the high-strength conducting composite material that the body carbon fiber forms and constitute; Said enhancing body carbon fiber is the carbon fiber composite filament that carbon fiber wire, ceramic fibre silk and glass mat are processed by thermosetting resin cured typing, and wherein said carbon fiber wire is the filament of being processed by polyacrylonitrile-based carbon fibre cellulose mixture carbon fiber.
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.
