Description
Technical field
The present invention relates to the cable technology field, relate generally to a kind of cable making method that is used for HTGR.
Background technology
HTGR is made cooling agent with helium, and the nuclear reactor HTGR that outlet temperature is high adopts coated particle fuel, makes moderator with graphite.Core exit temperature is 850 ~ 1000 ℃, even higher.HTGR has that the heat efficiency is high by 40% ~ 41%, and burnup is dark, and is maximum up to 20MWd/t uranium, and conversion is than advantage such as high 0.7 ~ 0.8.Because the helium chemical stability is good, good heat-transfer, and also it is little to induce radioactivity, can waste heat safety be taken out of after the shutdown, and security performance is good.The cable of using at HTGR CRDM rod position measuring system, stepping motor and driver; Require high; Can be high at 250 ℃ of high temperature, humidity, relative humidity 90%, normal operation there are under the condition of certain radiation dosage 60 years, promptly cable need reach the requirement of nuclear safe level 1E level K1; And this occasion use cable to lay the space less, require cable that higher conductivity and less external diameter are arranged, so that laying installation.In this type occasion, can cause heavy losses to equipment, life, property safety in case have an accident.So various device, control system, measuring system are required all very strict, can't permit least bit mishap, and it is just higher to control the requirement of cable of these equipment, will rectificate useful life.At present, the cable that use in existing traditional core power station is to adopt zinc-plated soft copper conductor as master core, and conductivity is low, and conducting effect is poor, and temperature resistant grade also can only reach 125 ℃.
Publication number is CN 1760996; A kind of production method of fire resistant communication cable was disclosed for the Chinese patent document of 2006.04.19 in open day; The production method that it is characterized in that said cable is: the first step, select PC base-material polyethylene and two kinds of cable insulation materials of crosslinking agent for use, just by being fit to high polyethylene and a kind of suitable crosslinking agent of low-k, low dielectric loss angle, voltage withstand class that real core is fit to the physical blowing extrusion again; Second goes on foot, above-mentioned polyethylene and crosslinking agent is mixed on mixing roll according to a certain ratio; The 3rd step, after guaranteeing that each component mixes, extruding pelletization; The 4th step, with this polyethylene particles that has added crosslinking agent extrusion insulation heart yearn that on the physical blowing board, foams; The insulation heart yearn of the 5th step, this foaming extrusion is that the electron irradiation of 100KGY is crosslinked to produce through irradiation dose; The 6th the step, outside crosslinked good foamed insulation heart yearn, make screen; By operation, so far, accomplished the whole process of production of fire resistant communication cable outside the 7th step, the completion at last.Still there is following shortcoming in this technical scheme: make the coaxial cable of insulating material through crosslinked polyethylene foamed, temperature resistant grade can only reach 105 ℃.Can't satisfy adaptability, particularly relate to and be higher than the above hot environment of 200 degree Celsius, cause the insulating barrier easy ageing, influence cable useful life ambient temperature.Therefore, the cable of this technical scheme production can't reach the requirement of nuclear safe level 1E level K1.
Summary of the invention
The present invention is intended to can't satisfy ambient temperature to the cable of prior art manufacturing; Especially the adaptive defective that is higher than the above hot environment of 200 degree Celsius; A kind of cable making method that is used for HTGR is provided; It is strong to adopt the produced cable of this method to have environmental adaptability, and conductivity is high, the characteristics that electromagnetic compatibility is strong.
In order to realize the foregoing invention purpose, the technical scheme that the present invention adopts is:
A kind of cable making method that is used for HTGR comprises selecting materials-wire drawing-conductor is stranded-finished product manufacturing-finished product packing warehouse-in technological process, it is characterized in that: also comprise annealing-insulating barrier extrude-oversheath extrudes manufacturing process flow; Said annealing is meant that annealed silver plating machine is 6～20 μ m silver at copper monofilament surface plating thickness; Described insulating barrier is extruded with oversheath and is extruded the screw rod that is meant employing high compression ratio 3.5:1～5.0:1; Extrusion equipment has good cooling device; It is extruded processing temperature and is controlled at 360～420 ℃, and its extrusion die is selected the crowded pipe mold of high draw ratio configuration for use, and the apolegamy draw ratio is 30～50.
Described wire drawing is meant that a plurality of wire-drawing dies by electrician's round copper rod process drawing device are drawn into the copper monofilament.
Described conductor is stranded to be meant by the multiply silver-gilt copper wire strandedly according to concentric type, and the twisting pitch scope is 10～40mm.
The present invention is in the twisted wire process; Adopt the doubling mould in 1.0～4.0mm aperture, than the little 2～5%d of doubling mould size of the common twisted wire of same specification, wherein d is a mould sizing area diameter; Make the conductor thread core outward appearance rounding, tight, bright and clean of strand system, and help insulating extrude effect.
The present invention adopts the screw rod of high compression ratio, its objective is in order to satisfy polyetheretherketonematerials materials to be difficult to plastify good particularity, and makes it fully plastify compacting, can not produce pore because of high temperature.
The present invention adopts the crowded pipe mold of high draw ratio configuration, its objective is and satisfies the polyetheretherketonematerials materials processing characteristics, is generally 30-50 because polyetheretherketonematerials materials gets draw ratio.

Compared with prior art, beneficial effect of the present invention mainly shows the following aspects:
One, insulating barrier and outer jacket are polyether-ether-ketone, make that cable can normally operation in ambient temperature-10 ℃～250 ℃ scopes, have very strong environmental adaptability; And because polyether-ether-ketone has excellent mechanical and physical performance, higher specific insulation, and good thermal stress cracking and radiation resistance, insulating barrier and outer jacket thickness can reduce, and it is little by 20～40% that the outside diameter of cable is compared other similar cables.Prolonged useful life.
Two, conductor adopts the silver-plated copper conductor, and its conductivity improves 3～5% than zinc-plated soft copper conductor.
Three, cable is provided with silver-coated copper wire braiding sub-shield and silver-coated copper wire weaves total screen; Has better electromagnetic compatibility; Play good effect to suppressing electromagnetic interference, effectively controlled the interference between the external world and the core, improved accuracy Equipment Control, measurement; Reliability is high, and the cost of operation control is low.
Four, the present invention is in the twisted wire process; Adopt the doubling mould in 1.0～4.0mm aperture, than the little 2～5%d of doubling mould size of the common twisted wire of same specification, wherein d is a mould sizing area diameter; Make the conductor thread core outward appearance rounding, tight, bright and clean of strand system, and help insulating extrude effect.
Five, the present invention adopts the screw rod of high compression ratio, its objective is in order to satisfy polyetheretherketonematerials materials to be difficult to plastify good particularity, and makes it fully plastify compacting, can not produce pore because of high temperature.
Six, the present invention adopts the crowded pipe mold of high draw ratio configuration, can satisfy the polyetheretherketonematerials materials processing characteristics, is generally 30-50 because polyetheretherketonematerials materials gets draw ratio.
