Description
Technical field
The present invention relates to reactor with 1E level K1 class flexible power cable, refer in particular to the 1E level K1 class power cable that can be used for (nuclear power station, nuclear-powered submarine etc.) nuclear island inside.
Background technology
By 2009, only 9,080,000 kilowatts of China's nuclear power installation amounts by the medium-term and long-term development plan of nuclear power that China in 2007 works out, were planned the construction of the year two thousand twenty nuclear power and will be reached 4,000 ten thousand kilowatts (also only account for total installed capacity amount 4%).But it is extremely rapid that I am stranded actual nuclear power construction development, and this nuclear power installation amount will be advanced to " 12 " and finish, and totally carry the first five years.China's project in construction is 10 at present, and that establishes has 21, expects before the year two thousand twenty, with the nuclear power generating sets of newly-built 27 million kilowatts.In view of the above, the nuclear power developing speed of China is exceedingly fast, and the space is very big, will form up to the market space more than trillion.China National Nuclear Corporation wishes that the average localization rate of parts and components of newly-built nuclear power station can reach 60%, so have the nuclear power construction production domesticization of 6,000 hundred million RMB at least, this has brought fabulous opportunity for the production domesticization research and development of China 1E level K1 class cable.1E level K1 class cable is near the cable that uses (especially advanced lines rank) of nuclear island particularly, mainly relies on import.Conservative estimation, used in nuclear power station 1E level cable access every year is up to 12,000,000,000 yuan.
Along with the integral body raising of equipment technology, the construction of nuclear power station is to third and fourth generation, even the development of the 5th generation.Fail safe, reliability requirement to nuclear power station are more and more higher, and corresponding cable requires also corresponding raising.From requiring to change early stage 40 years working lives of 1E level K1 class cable requirement, 90 ℃ of long-term work temperature, accumulative total irradiation dose 2.5 * 10
5Gy; 1E level K1 class cable requires 50 years working lives (even 60 years) now, 180 ℃ of long-term work temperature, accumulative total irradiation dose 3.5 * 10
6Gy, performance requirement improve very fast, therefore need a kind ofly novel not only satisfied serviceability and require but also make things convenient for the power cable of laying installation to replace the cable of existing type.Polyether-ether-ketone insulation and sheath flexible power cable are a kind of excellent selections of satisfying this type of high request.
The polyetheretherketonematerials materials rigidity is bigger, still has 12～13MPa in 250 ℃ of following bending strengths and compressive strength, is in close proximity to metallic aluminum material.Therefore, select for use polyetheretherketonematerials materials to make the insulation and the sheath of power cable, if adopt conventional technical scheme, the conventional construction of cable and production technology, can face the very big caused cable of this kind material hardness can't be crooked and directly cause and can't use.Therefore, the power cable of insulation of polyether-ether-ketone flexible compound and sheath just arises at the historic moment.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of used in nuclear power station 1E level K1 class power cable, refers in particular to the inner power cable that uses of nuclear island.This cable can satisfy 250 ℃ of long-term work temperature, largest cumulative irradiation dose 1.0 * 10
7Working life is 50 years under the situation of Gy; Environment for use relative humidity 90% (nominal situation) and 100% (accident conditions); The LSOH anti-flaming of cable own, asepsis environment-protecting; Can pass through vertical bunched burning test.When greatly improving cable performance, the also laying installation (especially in limited space, such as occasions such as nuclear-powered submarines) that greatly makes things convenient for cable because of the flexibility and the flexible of cable itself.
The technical problem that the present invention solves is to be achieved through the following technical solutions: cable comprises fexible conductor, the insulation of polyether-ether-ketone flexible compound layer, metallic shield (optional) and polyether-ether-ketone flexible compound outer jacket (optional) from inside to outside.
Described fexible conductor coats the insulation of polyether-ether-ketone flexible compound layer outward, forms polyether-ether-ketone insulation heart yearn.Single or many polyether-ether-ketone insulation heart yearns are twisted into cable core by stranding equipment.Cable core behind the stranding is outer can directly to coat polyether-ether-ketone flexible compound outer jacket; Or clad metal always shields as required, the outer polyether-ether-ketone flexible compound outer jacket that coats again of total shielding.
Wherein said conductor is by the silver-gilt copper wire or the nickel plating copper wire that adopt the 5th class conductor structure, and adopt flexible preparation technology (each layer strand is to the different of, twisting pitch and cooperate) multilayer to twist again and form, the outward appearance rounding can keep cable to have good bending property and electrical property.
Wherein said metal screen layer adopts silver-gilt copper wire, the braiding of nickel plating copper wire.Count should make cable have good shielding properties greater than 80%.
Wherein said polyether-ether-ketone flexible compound insulating barrier and polyether-ether-ketone flexible compound outer jacket adopt the comprehensive softening technology of another proprietary technology-cable CSCT (Composite-Soft-Cable-Technology contains special tooling mould, insulating sleeve softening design and MULTILAYER COMPOSITE preparation technology etc.) design and make, with flexibility and the flexible that guarantees whole cable.
The present invention selects compound inslation, the composite jacket of polyether-ether-ketone as cable for use, and therefore, this cable has excellent especially performance, has greatly satisfied the requirement of advanced lines nuclear power to 1E level K1 class power cable; Because this cable has adopted the CSCT proprietary technology, reduced the outside diameter of cable (more than 20%) again, greatly improved the flexibility and the flexible of cable, its flexibility and bending property are equivalent to or are better than other type power cable of same specification.
The existing relatively 1E level of cable of the present invention K1 class power cable, performance advantage is obvious:
1. 250 ℃ of long-term work temperature;
2. the largest cumulative irradiation dose 1.0 * 10
7Working life can reach more than 50 years during Gy;
3. but environment for use relative humidity 90% (nominal situation) and 100% (accident conditions);
4. the LSOH anti-flaming of cable own, asepsis environment-protecting;
5. can spread test by the bunched cables vertical combustion;
6. littler more than 20% than the same specification outside diameter of cable, the cable deadweight is also little about more than 10%, uses the advantage that has more on nuclear-powered submarine;
7. processing technology is simple, and technology is easily grasped, and can save energy in the production;
