Description
Technical field
The present invention is to the improvement of aerial condutor with load-bearing component continuous high-intensity fiber resin-based composite core and preparation method, relates in particular to a kind of good bandability, and the aerial condutor that can bear radially grip pressure power is with composite core and preparation method.
Background technology
Continuous high-intensity fiber resin-based composite core, with in light weight, stretching resistance is strong, the coefficient of expansion is little, can bear high temperature (for example more than 180 ℃) operation, sag is little, replaces zinc-coated wire as the aerial condutor load-bearing component, draw anharmonic ratio, low arc drop, low sag, low creep, low line loss, high temperature resistant greatly with what realize aerial condutor, obtained domestic and international power industry favor.
Prior art for preparing aerial condutor load-bearing component---continuous high-intensity fiber resin-based composite core, for example the applicant formerly applies for a patent CN2847470, and the described aluminium conductor of Chinese patent CN1649718 strengthens cable composite core, Chinese patent CN101572132 transmission pressure glass fibre and carbon fiber complex core, the compound strengthening core of Chinese patent CN101325098 high-intensity fiber, Chinese patent CN201237921 power transmission cable are with composite core etc.Its inside and outside core all adopts with a kind of high temperature resistant thermosetting resin (for example vitrification point 〉=180 ℃ epoxy resin) heat of immersion curing molding, and the ectonexine fibre core is all to bear pulling force.The high temperature resistant thermosetting resin, the crisp hard attitude that is similar pottery after the curing, all solidify the continuous high-strength fiber composite core that obtains by this class by the thermosetting animi resin, found some inevitable inherent defects in actual use: the one, the hardness of solidifying the back core is big, cause the composite core bending radius big, minimum bending radius is about 50 times of diameters, makes troubles for production, payingoff construction; The 2nd, it is crisp rigid big to solidify the back resin, fracture toughness, and poor impact resistance, damage tolerance is lower, it is stressed that vertically easy to crack (longitudinal cracking can cause the composite core performance to descend significantly, lose the composite core meaning), easily cause potential safety hazard, radial mechanical performance extreme difference particularly, can not bear radially grip pressure power, cause in erection process, can not adopt common steel core lead mainly with the connection gold utensil of crimping mode, need to be equipped with the carrying pulling force and rely on mainly that frictional force is main special-purpose gold utensil between composite core and gold utensil.And the special-purpose common crimping armor clamp of gold utensil that connects costs an arm and a leg, and a cover often needs much to connect gold utensil about 5000-6000 unit on the circuit, increased construction of line cost greatly, has limited applying of compound core conducting wire.
The applicant once proposed the composite core structure that outer layer fiber adopts canoe in Chinese patent CN200962340, but resin still is unified thermosetting resin.Though improved composite core radial strength and resisting longitudinal cracking behavior to a certain extent.Yet because the sclerosis and the fragility defective of thermosetting resin do not improve usually, therefore above-mentioned shortcoming still exists.
Above-mentioned deficiency still has is worth improved place.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, a kind of not only good bandability is provided, and can bears radially grip pressure power, damage tolerance than big aerial condutor with continuous high-intensity fiber resin-based composite core.
Another purpose of the present invention is to provide a kind of preparation method of above-mentioned composite core.
The present invention's first purpose realizes, the main improvement: one is to use the stranded composite core of the many stranded compositions of single composite core of composite core employing, to improve the bending property of composite core; The 2nd, the outermost resin of the single composite core of stranded usefulness, use the flexible resin of vitrification point 〉=180 ℃ instead, bear radially grip pressure power to improve composite core, increase the damage tolerance ratio, making it to adapt to aerial condutor does not ftracture with the grip pressure power of gold utensil with common connection, thereby overcome above-mentioned prior art deficiency, realize the object of the invention.Specifically, aerial condutor of the present invention is with continuous high-intensity fiber resin-based composite core, comprise ℃ resin solidification polymerization of at least a continuous high-intensity fiber through vitrification point 〉=180, it is characterized in that composite core is by many stranded the forming of single composite core, described single composite core is at least by inner fiber resin core and outer layer fiber resin core concentric compound composition, wherein the outer layer fiber cured resin except that sandwich layer is the flexible resin of vitrification point 〉=180 ℃ at least, outer layer thickness 0.5～3mm.
Among the present invention:
Dan Fuxin; at least by inside and outside bilaminar fiber resin concentric compound composition; the center internal layer is mainly to bear pulling force; still adopt prior art thermosetting resin cured; to give full play to all high-intensity fiber performances; outer (can comprise time outer) tries hard to keep and protects core mainly as bearing grip pressure in the present invention; do not make it ftractureed by the gold utensil compression; improve the damage tolerance ratio; simultaneously to improving bending property; strengthen tension respective action is also arranged; its resin adopts and is different from the existing animi resin that is hard attitude after prior art is solidified, and changes into and adopts the flexible resin that has certain flexibility after the curing.Be that the present invention is except that outer resin difference; All the other all can be identical with the prior art composite core, for example the ectonexine fiber can adopt the identical high-intensity fiber of former composite core (such as but not limited to carbon, Kev draw, basalt, glass, aramid fiber, aluminium oxide, carborundum, boron, aromatic polyamides, liquid crystal fiber, high-performance polyethylene fibres, high-performance finer wire, alloy silk etc.), internal layer core resin adopts former composite core same resin.Each layer continuous fiber can be single fiber, also can be two kinds or above fiber mixing, and fiber volume fraction is more than 50%, 50-80% for example, and they are prior art.Consider that the Dan Fuxin force way changes to some extent than the prior art composite core, the whole tensile strength of internal layer core fibre, better 〉=2500Mpa, for example tensile strength 2500～4000Mpa; Outer layer fiber tensile strength then allows to select suitably to hang down the fiber (can certainly be identical with inner fiber) of some, to reduce cost.The outer layer fiber form can be that continuous fiber vertically coats and/or twines, and also can be coatings such as fiber cloth, felt, net.Outer core thickness 0.5～3mm, for preferred values is determined in the test of different-diameter lead, too small then might causing of thickness compresses at gold utensil under (pressure satisfies tractive effort) power to internal layer core resistance to compression protection inadequately, can cause destruction, also just lose meaning of the present invention the internal layer core; Blocked up not only do not have a practical significance, can cause the increase in core cross section under the identical pulling force on the contrary.Look diameter of wire, skin can be that one deck also can be a multilayer, for example 1～2 layer.
Outer core flexible resin, with respect to being hard fragility (similar pottery) cured resin after the curing that existing composite core is used for example for the thermosetting resin, refer to have after it solidifies thermosetting that existing relatively composite core uses for example epoxy resin certain compressive strain amount is arranged, can bear and connect the gold utensil compression and indehiscent resin, solidify the back percentage elongation greater than the internal layer core, compression strength is lower than the internal layer core, for example solidify back percentage elongation 〉=8%, compression strength 〉=50MPA, less than the internal layer core, the flexible resin of vitrification point 〉=180 ℃.If the resin percentage elongation is low excessively behind the solid, be subjected to big pressure still easy to crack; Pressure resistance is spent low, and then external force is difficult for being passed to inner core, causes enough tractive effort by holding with a firm grip.The outer flexible resin that uses, make connection gold utensil and composite core stressed, by original main dependence and composite core frictional force is main, becomes to adopt commonly to be connected to main (compression is a main stress) to compress, and connects gold utensil and adopts the general gold utensil of aerial condutor thereby can make.Flexible resin, it can be a thermoplastic resin, it also can be thermosetting resin, as long as satisfy to use vitrification point is required (for example vitrification point 〉=180 ℃), can adopt the commercially available curable flexible resin that serviceability temperature requires that meets, also can adopt the existing resin that composite core is used that meets, epoxy for example, phenolic aldehyde, polyether-ether-ketone, polysulfones, polyimides, fluoroplastics, nylon, modified poly ethylene, modified polypropene, modified poly ester, Merlon, polyphenylene sulfides etc. carry out flexible modification to be handled, it is curing agent modified for example to add flexibility, and this belongs to prior art.They for example are the flexible polyurethanes (NP1851) of ALH SYSTEMS company; Guangzhou is the acrylic acid modified polymer (SG-1155) of state's industrial chemicals Co., Ltd still; the phenol-formaldehyde resin modified of Shanghai poly-good fortune chemistry Co., Ltd; the modified organic silicone resin (WD-304) of Gao Anwande organosilicon material Co., Ltd; the modified epoxy (PLM-3203) of Zhuzhou generation woods polymer Co., Ltd, the lucky agate in the Shanghai Co., Ltd's epoxy resin (G40122) etc. of refining.
Ectonexine plexiglas temperature requirement is mainly considered from lead long-time running temperature angle, if the vitrification point of cured resin is low excessively, then can reduce the operating temperature of lead, has also just lost the meaning of composite core as the lead load-bearing component.For making lead that higher ampacity be arranged, ectonexine plexiglas temperature, more preferably 〉=200 ℃, be preferably 〉=210 ℃, the vitrification point of resin is high more, the operating temperature that lead can bear is also just high more, and its ampacity of same conductor cross section is also high more, and the superiority of compound core conducting wire is also just obvious more.
The stranded composite core of the present invention, for convenient stranded and help bendability and improve, test determines that the single composite core sectional area of stranded usefulness better adopts 3～15mm
2Single composite core is meticulous, and the one, existing pultrude process realizes that difficulty is relatively large, the 2nd, can influence tensile strength, can not give full play to the high-intensity fiber effect; If cross slightly, be unfavorable for the follow-up core that is twisted into.
The single composite core cross sectional shape of stranded usefulness is not limit, can be common circle, zigzag, ellipse, also can be the special-shaped non-round structure of similar molded lines conductor, as trapezoidal, quincunx, watt shape, fan-shaped, Z-shaped (it is valueless that non-stranded single core is done form wire, so be the circular section).Lay configuration, a kind of outermost layer that is preferably adopts non-round line, can bear more high radial grip pressure power.
In above-mentioned single composite core diameter range, the stranded number of plies is comparatively suitable with layer 2-4, and 5～25 times of stranded lay ratios, and from inside to outside stranded lay ratio reduces help the Stability Analysis of Structures after stranded.The stranded number of plies is too much, stranded complex process, and stranded difficulty increases, and does not also have practical significance.Stranded composite core structure can be that the single composite core of same cross-sectional is regular or informal stranded, also can be that different cross section list composite core is informal stranded.A kind of better twisted cores structure of the present invention, outermost layer adopt molded lines list composite core, and helping reducing the gap increases the cross section, makes can reduce the twisted cores cross section under identical tensile strength, and can improve the twisted cores surface smoothness.
Composite core preparation of the present invention can be adopted the single composite core of pultrusion and be stranded in the technological process and finish, and for example is used for few number of plies as 2 layers of twisted cores; Also can adopt the single composite core of moulding to separate with multicore is stranded, this method can be used for for example twisted cores more than 3 layers of multilayer.Wherein maximum is different from prior art, and for single composite core moulding is divided into regelate, i.e. semi-solid preparation moulding is finally finished curing after stranded.Specifically, aerial condutor of the present invention comprises the high-intensity fiber impregnating resin with continuous high-intensity fiber resin-based composite core preparation method, the hot curing typing, it is characterized in that fiber impregnated resin heating obtains semi-solid preparation list composite core, many stranded after, be heated to full solidification.
In the inventive method:
The fiber resin matrix composite core, being heating and curing was divided into for two steps, and pre-profiling heating is the semi-solid preparation core, heats to full solidification after stranded again.The pre-profiling semi-solid preparation, with respect to the prior art for preparing composite core be heating and curing once finalize the design for, refer to the fiber impregnated resin pultrusion, be heated into semi-cured state (mainly playing styling), be heating and curing as long as a condition does not reach solidifying requirements in curing time and/or the temperature, products obtained therefrom is semi-solid preparation (the equal semi-solid preparation of ectonexine).The present invention adopts semi-solid preparation typing composite core stranded, be heated to the full solidification mode after the stranded moulding again, mainly be to consider from helping being twisted into core, not only semi-solid preparation helps stranded (if stranded again after single core full solidification, then can cause back twist when stranded), and further solidify by resin after stranded, helping cohesive force raising between stranded each single core, the composite core globality is better.Its single composite core preparation, except that outer resin adopted curable flexible resin and regelate, all the other were all same as the prior art, for example are heating and curing by the impregnating resin pultrusion.
Stranded mode can adopt incorgruous stranded mode between common lead stranded layer, because interlayer has resin-bondedly, also can adopt the stranded in the same way mode of interlayer, and can not cause stranded in the same way back loose.Single core is twisted into core, and potting resin can not be filled with and outer identical flexible resin yet, floods flexible resin when promptly multicore is stranded again.The present invention better adopts flexible resin to fill, and both can play stronger mutual cementation, also helps further improving radially anti-pressure ability of twisted cores, can better protect the internal layer sclerosis core of each single composite core not ftracture.
For this reason, ectonexine resin of the present invention is better selected long relatively resin curing time, for example 2-5 minute curing time, if curing time is too short, is unfavorable for regelate; Curing time is long, can influence speed of production and efficient again.
In addition, be further to improve radially anti-pressure ability of composite core, a kind of better is at the outer wrapped or vertical bag one deck low modulus of twisted cores, resistant to elevated temperatures filament, net, felt, cloth, is impregnated with flexible resin during more preferably wrapped or vertical bag.
Aerial condutor of the present invention is with continuous high-intensity fiber resin-based composite core, with respect to prior art, because one adopts many thin relatively composite core lay configuration, two each single composite core outermost layer at least adopt flexible resin to solidify, not only make gained composite core integrally bending performance be improved significantly, minimum bending radius is stranded back 40 times of diameters or littler, has obviously than the single composite core of prior art to reduce, both make things convenient for production, transportation, and made things convenient for wiring to set up again; And because of after the flexible resin curing certain pressure distortion amount being arranged, can bear radial compressive stress, damage tolerance is than big, thereby can adopt lead directly to be connected with the construction gold utensil in the crimping mode with common gold utensil (each about about 200 yuan), and can not taking place, composite core do not ftracture, test uses common aerial condutor not find cracking with gold utensil crimping (satisfying pulling force), greatly reduces to use to set up cost and operating expenses, more helps applying.Damage tolerance has also improved safety in utilization than big.The moulding of semi-solid preparation mode is adopted in single composite core preparation, and pultrusion speed can be accelerated greatly, and because of stranded holding time not substantially, therefore whole composite core speed of production can adopt animi resin to improve 20-50% more originally.Initiate the compound outer flexible resin that adopts and solidify, and adopt the stranded composition composite core of multicore, this is different from two main innovate point of prior art for the present invention.
Below in conjunction with some specific embodiments; essence of the present invention is further understood in exemplary illustration and help; but the embodiment detail only is for the present invention is described; do not represent the present invention to conceive whole technical schemes down; therefore should not be construed as the technical scheme qualification total to the present invention, some are In the view of the technical staff, and the unsubstantiality that does not depart from the present invention's design increases and/or change; for example simple the change or replacement of technical characterictic to have same or similar technique effect all belongs to protection range of the present invention.
