Description
Technical field
The utility model relates to a kind of cable, especially relates to the crosslinked polyetylene insulated full intelligent cleaning cable of a kind of 66～750kV.
Background technology
As everyone knows, at present except each large hydroelectric power generation of China, wind-force, waterpower and nuclear power station development are rapidly, except " two horizontal two is vertical " intelligent electrical network of national grid, in each province and city, built again intelligent electrical networks such as " three horizontal two vertical rings or one horizontal two vertical four stations ", the construction of these large-scale power grids and development, improve and higher requirement the transmission of the supervision of the operation conditions in electric power transfer process and information.Requirement being to whole distract, transprovincially the electrical network delivery of electrical energy situation in district is systematically supervised and regulates and controls, and except each aerial condutor and built on stilts expanded conductor, also needs the crosslinked power cable with cross-linked polyethylene insulation of 66～750 kV to carry out electric power transfer.Because 66～750kV electric pressure crosslinked polyetylene insulated has that environment for use is severe, system is complicated, with high content of technology, manufacturing technique requirent is harsh and the feature such as complicated.Need professional VCV fabricating tools, accessory kit etc. simultaneously.And most of 66kV of manufacturer and above high pressure, ultra-high voltage cross-linking polyethylene-insulated power cable be in product use procedure, the safety that all cannot align the operation of a cable is effectively supervised.Traditional method for supervising, for detect the thermometric mode that position is carried out point-to-point observing and controlling or bundled ground at jacket surface at cable emphasis, cannot meet the requirement to functions such as temperature-time monitoring, prevention of accident, fault alarms in crosslinked cable running.
So, crosslinked cable is in the monitoring of use procedure and be maintained into nose heave wanting, in the past, crosslinked cable generally adopts point-to-point or the measurement of jacket surface cluster or monitor mode in running, and this mode is product laid after, distributed temperature measuring optical unit is banded in to the surface of product (sheath), can not feeds back truly the practical operation situation of product.Add again the impact of cable laying and surrounding environment, can not guarantee the safe operation of cable system.Traditional sheath material is pvc sheathing compound, flame-proof polyvinyl chloride sheath material or low smoke and low halogen pvc sheathing compound, in material, contain the harmful substances such as halogen (poly-bromo biphenyl, poly-bromo biphenyl ether), in fire proofing, adopt the series materials such as lead, bromine as fire retardant, not only environmental protection is had to pollution to a certain degree, but also can be to causing eyes spasm, have a running nose, sneeze, the symptom such as skin dermexanthesis, skin abnormality.
Summary of the invention
The utility model is mainly for the existing above-mentioned technical problem of prior art, and a kind of precise monitoring that can be to temperature, insulating barrier temperature outside in conductor running is provided; The crosslinked polyetylene insulated full intelligent cleaning cable of 66～750kV with excellent fire-retardant, heat resistance, UV resistant irradiation performance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the crosslinked polyetylene insulated full intelligent cleaning cable of a kind of 66～750kV, comprise conductor and be arranged on the conductor shield outside conductor, conductor shield is arranged with insulating barrier and insulation screen outward, it is characterized in that described insulation screen is arranged with buffering water blocking layer outward, described conductor middle part and the outside of buffering water blocking layer are symmetrical arranged one-to-many mode fiber unit, described buffering water blocking layer is arranged with metallic sheath outward, described metallic sheath, in metallic sheath, be symmetrically arranged with a pair of monomode fiber unit.The utility model is a kind of crosslinked polyetylene insulated full intelligent cleaning cable of 66～750kV that delivery of electrical energy, efficient monitoring temperature and fiber-optic communications traffic are combined, this crosslinked full intelligent cleaning cable not only can complete normal cable transmission and safe optical communication transmission, and can be in cable running, conductor operating temperature, the monitoring of surface of insulating layer temperature-time, prevention of accident, fault alarm function.Different according to the function realizing, adopt different fiber types, in the middle of conductor, with the symmetrical one-to-many mode fiber unit of placing, the outside of cushioning water blocking layer, realized the precise monitoring to temperature, insulating barrier temperature outside in conductor running; What another was placed symmetry is monomode fiber unit, has realized the communications between end and end.Light unit core number can be 2,4,6,8 cores.Monomode fiber attenuation coefficient for communications: attenuation coefficient maximum is 0.36dB/km when using wavelength 1310nm, when using wavelength 1550nm, attenuation coefficient maximum is 0.22dB/km; And the multimode fiber attenuation coefficient of monitoring for thermometric: when using wavelength 850nm, attenuation coefficient maximum is 3.0dB/km, and when using wavelength 1300nm, attenuation coefficient maximum is 1.0 dB/km.
As preferably, described metallic sheath is provided with asphalt corrosion resistant layer outward.Pitch generally adopts the operation anticorrosive coat of high-melting-point, high adhesion, resistance to embrittlement special asphalt.
As preferably, described asphalt corrosion resistant layer is provided with clean restrictive coating outward.Clean sheath is: not halogen-containing polyolefine material, as: high-density polyethylene material, fire-retardant halogen-free polyolefin material or, the clean sheath materials such as ethylene propylene rubber insulated level protective cover material, can in sheath material, add the environment-friendly type compositions such as appropriate carbon black, protection against rodents, anti-ant, make sheath there is excellent fire-retardant, heat resistance, UV resistant irradiation performance, 90 ℃ of long-term work temperature; And there is excellent non-water absorbing properties, in formula, suitably add the processing aid of certain content, effectively improved the mobility of material, improved its production efficiency, realize high efficiency manufacture simultaneously.
