Abstract
The invention discloses a glass fiber and carbon fiber composite core for a wire of a transmission line, which is characterized by consisting of 50 to 55 percent of carbon fibers, 10 to 15 percent of glass fibers and 30 to 40 percent of resin and auxiliary materials. Carbon fiber yarns pass through fibers-converging stander to be converged into a rounded body to be drawn outward; glass fibers cover the carbon fiber rounded body from a plurality of layers of creels and are drawn outward; and the carbon fiber rounded body covered by glass fiber yearns is synchronously drawn outward to pass through a mould. A well-stirred resin raw material can be poured into a resin storage tank 5 after being sieved by an 80 mesh sieve. The temperatures of a curing region and a forming region in the heating mould are set to be 200+/-10 DEG C and 140+/-10 DEG C respectively, and the heating mould is electrically heated. A heating system of an extruder is started, and the temperatures of heating areas are adjusted according to process requirements. The class fiber and carbon fiber composite core can well solve the problem of the combination of a thermosetting process and a thermoplastic process, thereby achieving excellent product quality and fulfilling a preset technical solution target.
Description
Technical field
The present invention relates to the overhead transmission line conductor field, concrete relate to transmission line wire glass fibre and carbon fiber complex core.
Background technology
Along with the continuous progress of material technology, people's trial in 20 end of the centurys replaces metal material to make the core of lead with organic composite material, has developed the synthetic core lead of advanced composite material (ACM).This lead has been given full play to the characteristics of organic composite material, compare with present various aerial condutors, have in light weight, intensity is high, Heat stability is good, degree of speeding is low, ampacity is big, corrosion resistant characteristics, from energy-conservation, save land, aspect such as material-saving, environmental protection, raising ability to transmit electricity, have good application prospects, be specially adapted to the transformation of old circuit.The nineties in 20th century, Japan developed the synthetic core lead of composite material, and product is divided into two kinds of carbon fiber core aluminium stranded conductor (ACFR) and heat-resisting carbon fiber core heat-resisting aluminium alloy twisted wires (TACFR), and the former has tested more than 4 years at actual track.Composite material core wire mainly is made of carbon fiber and thermosetting resin.Coat unhardened thermosetting resin strand together with the PAN based carbon fiber that 12000 diameters are 7 μ,, be twisted into compound twisted wire with 7 strands then being wrapped with strand of organic fiber formation.Through last heat treatment resin is hardened fully again, form composite material core wire at last.The composite core line mass is the about 1/5 of conventional steel core, and coefficient of linear expansion is about 1/12.Evidence, the tensile strength of this advanced composite material (ACM) core lead is considerably beyond ACSR, and stress at normal temperatures---elongation characteristics presents elastomer, does not have the plastic degeneration, and the elongation when disrumpent feelings is littler than steel strand wire, is about 1.6%.Thermal endurance is basic identical with ACSR.
What the synthetic core lead developmental research of U.S.'s advanced composite material (ACM) was comparatively successful is CTC company, and it is synthetic core lead---the carbon fiber complex core aluminium stranded conductor of composite material of ACCC that the said firm in 2003 has released model again.Its heart yearn is to be that central core and glass fibre coat the single plug of making by carbon fiber, and carbon fiber adopts polyamide refractory process, carbonization to form; The epoxy resin of high strength, high tenacity prescription has very strong resistance to impact, anti-tension stress and bending stress.After carbon fiber and glass fibre carried out pre-stretching, epoxy resin impregnated, curing molding was a composite material core wire in the high temperature mould then.Outer and the adjacent skin of heart yearn is a trapezoid cross section aluminum steel thigh.Lead has been finished conventional type approval test, has favorable mechanical characteristic and electrical characteristic.ACCC carbon fiber compound wire is the new product of traditional steel core aluminium hinge lead, aluminium Baogang lead, aluminium alloy conductor and import Yin Gang lead of the desirable replacement of present bulk of worldwide electricity power transmission and transformation system, ACCC carbon fiber compound wire compare with conventional wires have big, the low line loss of in light weight, intensity, sag is little, high temperature resistant, corrosion-resistant, with advantages such as environment is affine, realized the energy-saving and environmental protection and the safety of electric power transfer.
Domestic existing lead all is to be formed by wire that conducts electricity very well or bonding jumper.This lead tensile strength is low and not soft, uses frangibility.Owing to the characteristic of metal, expand with heat and contract with cold seriously with the variation of ambient temperature with metal lead, simultaneously to such an extent as to frequent lead self is broken when it is cold.Domestic also someone begin one's study carbon fiber complex core aluminium stranded conductor and carbon fiber complex core aluminium stranded conductor, but do not have concrete practical parameter, do not obtain substantial progress.The domestic people of having fiberglass reinforced plastics on probation is made strengthening core (FRP) with carbon fiber complex core though have high-strength light, corrosion-resistant, antistatic and anti-advantage such as nibble, and throughput rate is expired, and bending radius is bigger.
Summary of the invention
In order to overcome above-mentioned deficiency, main purpose of the present invention aims to provide a kind of novel, high-intensity, and the more glass fibre that is used for overhead transmission line conductor and the carbon fiber complex core of high practicability can be provided.
The basic problem that the present invention need solve is: select for use appropriate resin to combine with glass fibre as basis material; Form web frame plug in the lead jointly with the carbon fiber that is wrapped in inner core; Adopt new technology the combination in addition of above material.
The technical solution used in the present invention is: adopt epoxide resin material can obtain preferably associativity with glass fibre; Form web frame plug in the lead jointly by plating grid mold and the carbon fiber that is wrapped in inner core, specifically through strict temperature control heating, through drawing the bridge technological forming continuously and applying sheath section through plastic extruding machine, can better solve thermosetting technology and thermoplastic process in conjunction with problem, thereby obtain than the good quality production quality, reach predetermined technique and solve target.
The glass fibre of transmission line wire of the present invention and carbon fiber complex core are to adopt thermosetting technology composite glass fiber and thermosetting resin, and its diameter is 8mm～25mm; The carbon fiber complex core diameter is 6mm～20mm.
Glass fibre of the present invention and epoxy resin wrap carbon fiber strengthening core are to adopt thermoplastic process that PE is coated on the body of rod of the interior wrap carbon fiber strengthening core that glass fibre and thermosetting resin be composited.
In the heat curing process of glass optical cable strengthening core of the present invention mold heated is carried out strictness control, 140 ± 10 ℃ in 200 ± 10 ℃ in slaking zone and typing zone.
Basis material of the present invention is epoxy resin and vinylite.
The fine composite core of glass and resin and carbon is to be basis material with the glass fibre carbon fiber, and thermosetting resin is a kind of NEW TYPE OF COMPOSITE core of binding material.Its basic technology principle is consistent with the glass fiber cable strengthening core, has stronger operability technically, but glass fibre, carbon fiber have better mechanical property and physicochemical property than glass fibre, can overcome big, the heavier shortcoming of quality of glass fiber cable strengthening core bending radius largely, and have higher hot strength and anti-fracture characteristics, be the good substitute products of glass fibre strengthening core.
