The high enamel paint has light weight and 40% lower cost than copper wire. More importantly, the motor made of the high-magnetic enameled wire can save more than 20% of electric power, is beneficial to energy saving and carbon reduction, and is a novel invention in the scientific and technological industry.
Description
Technical field
The present disclosure generally relates to enameled wire composite conductor and its manufacture method, it is characterized in that using kelvin effect (skin
Efficiency) principle, by the high conductor arrangement of electric conductivity in enameled wire composite conductor outer, and accounts for the high conductor of the electric conductivity
60~65% (P≤60~65%A) of composite conductor gross area A.The relatively low conductor of electric conductivity, then be arranged in the composite conductor
Internal layer, accounts for 40~35% (Q=40~35%A) of composite conductor gross area A.P is the area of the high conductor of electric conductivity, and Q is to lead
The area of electrical relatively low conductor.
It has been found that using the function of kelvin effect, electric power is made uneven distribution in conductor propagation, work as outer
Conductor carry most electric power, and close to the conductor carrying fraction at conductor center electric power when, can so make compound
Conductor is with the current-carrying capacity for having identical copper conductor area during area equality of temperature, but its D.C. resistance is bigger than copper conductor by 20%.Therefore
The flux density of enameled wire its flux density ratio equal area copper enameled wire made by composite conductor is big by 20%.Since flux is close
Spending big by more than 20%, opposite torque also increases by 20%, with produce the horsepower of bigger or can reduce more than 20% electric power, thus
Rewrite the rule of every horsepower of consumption 0.746Kwh electric power.
Background technology
In the case where electronic industry constantly flourishes, whether have in terms of product function or the correlation technique of electronic component
Significant progress, the enameled wire so closed are still used based on traditional copper material, never changed over 100 years.It is in the streets even to have using copper-clad
Aluminium enamel-covered wire, but non-targeted mountain vallage product is only limitted to, sales volume is very little.It is main reasons is that the enamel-cover of copper-clad aluminum conductor
Line, its current-carrying capacity only has the 70% of copper, therefore cannot substitute copper enameled wire.
It is known that motor, generator, transformer are made of enameled wire.Flux density is bigger, and magnetic force is just stronger, shadow
The torque that bandit reaches is far-reaching.The length and resistance of enameled wire are to determine the principal element of flux density.
High enamel paint envelope curve is the composite conductor made by with two kinds of copper, aluminium metals, is experimentally verified that：In same area, with long
Degree, with temperature rise under conditions of, the current-carrying capacity of composite conductor is equal with copper wire, it is unique the difference is that D.C. resistance than copper wire direct current
Resistance is big, is its characteristic.It is stronger than the magnetic force of copper wire enameled wire that magnetic force caused by enameled wire is made with composite conductor.
Using existing motor, generator, transformer as model, copper is substituted with high enamel paint envelope curve by identical line footpath, length
Line, not only increases the enhancing of flux density magnetic force, can separately save electric power.Since high enamel paint envelope curve density ratio copper wire is small by 1/3, horse
The torque addend reached can infer.
Motor is that the magnetic fields generation strength of applied current makes the principle of coil motion.Generator is applied in magnetic field
Placement coil, flux is changed, coil will produce electric current electromagnetic induction effect.
Light-weight, the price cheaper than copper wire about 30% of high enamel paint envelope curve, based on its resistance characteristic, if using high enamel paint bag
Line produces motor, generator or can save electric energy, increase generated energy.Therefore just save cost, improve quality, carbon reduction speech,
It is preferable green product.
Enameled wire species is various, and not lower more than 20 plant, and the purpose is to depending on adapting to similar demand.Such as PD enameled wires, its characteristic
It is directly to weld；SS-NY enameled wires, heat-resisting 130 DEG C；ML enameled wires, heatproof are too numerous to enumerate up to 220 DEG C, etc. species.Enamel-cover
The method of line production, first with 100% conductive copper material, journey (dipping process) is soaked first with up-drawing method, SCR or be stained with
Be made 8mm Tong Wilsonii, it is secondary through slightly stretching, in stretch, carefully stretch the copper wire that various different sizes are made.After softened, then with insulated paint through more
Secondary application, drying, completion.Insulated paint used, can be depending on the preceding classification.
United States Patent (USP) US 3,777,361 discloses a kind of method for manufacturing covering filament, with the copper with lengthwise locking suture
Cover, wind the aluminum pole of unlimited length, drawing-in hydrostatic device.Copper is incorporated into aluminium by the heat and pressure of Extrusion, and works as copper
When cladding aluminum pole is extruded, welding locking suture, the copper clad aluminum steel silk of indefinitely long is made.
Other, United States Patent (USP) US 5,496,969 discloses a kind of invention of the strands of more filaments, has central stratum, at least by one
Filament is formed, and an additional layer, the filament containing plural number winding central stratum.
The content of the invention
Present invention system discloses a kind of high enamel paint envelope curve and its manufacture method first, be using copper aluminium as raw material, with pack or
Composite conductor made of method is staked on, its characteristic is：Under same area, the situation with temperature rise, the current-carrying of composite conductor and copper conductor
Amount is identical, but D.C. resistance is bigger than copper wire resistance by more than 20%.Industry knows that motor, generator, transformer are by enamel-cover
Thread, flux density is bigger, and magnetic force is stronger.Due to the D.C. resistance of composite conductor bigger than the D.C. resistance of copper wire 20% with
On, therefore the coil made by with high enamel paint envelope curve, the flux density of its flux density ratio copper wire are big by 20%.Due to high enamel paint matter
Amount is light, cost lower than copper wire 40%.Importantly, using motor made of high enamel paint envelope curve, electric power more than 20% can be saved,
There is very big benifit to carbon reduction, there is utility value in industry, be a big brand-new invention of science and technology.
