Enamel-cover multichannel is parallel parallel assembled highly-effective energy-saving paint envelope curve and manufacture using method thereof side by side

Technical field

The all trades and professions of China and the family life of people all be unable to do without electric energy.Widely using of electric energy, causes nervous situation also to the production supply of electric energy.The production of electric energy and use procedure also have contaminated environment to a certain degree, also exacerbate warming of weather.So how more effectively to produce delivery of electrical energy electric energy and use electric energy, effectively utilize electric energy, saves energy just becomes current extremely urgent significant problem.The electric energy that most of generator sends first flows to step-up transformer, gives So Far Away by ultra-high-tension power transmission line, to transformer station's step-down transformer, then gives distribution transformer, through switch to factories and miness, workshop and avenue.The transformer switchgear house in rural area gives each user, motor, electric equipment are for people to use.Electric current all be unable to do without wire through circuit remote like this, motor, transformer and electric equipment.Wire is the cradle of generating.Being the highway of transmission of electricity, is the ocean of electricity consumption.Ionization is not burst at the seams.But electric current all can produce thermal effect because of having resistance in the process of wire.Make a part of electric energy become heat to distribute in vain in atmosphere.Add temperature to our ambient air, exacerbate climate warming.Can so why they generate heat? that is exactly that the conductor of electric current in conduction has resistance to cause.So-called conductor is exactly the object with free electron.That is the conduction of electric energy is mainly transmitted by free electron.Our common wire is all the round conductor of copper, aluminium and their alloys.Copper aluminium has good electric conductivity.This invention relates to the problem that conductor cross-section girth increases, and inventive features changes round conductor in existing technology into oval wire.Single enamelled wire is changed into the thin core enamelled wire of many, make electric current divide multidiameter delay to run.Object wants to improve the efficiency of generator, motor, transformer and all power consumption equipments.

Background technology

We more extensively more in depth must be familiar with basic law and its particular law that research and probe sums up alternating current.People are often compared to the electric current of electronics in conductor the current of water pipe.I thinks a misunderstanding, water pipe is under identical hydraulic pressure, the water yield in the sectional area larger unit interval of water-supply-pipe internal diameter is larger, and be along with the increase of water pipe internal diameter sectional area is directly proportional increase, alternating current is not then along with the direct proportion that increases to of sectional area of wire increases, this is because the reason of the skin effect of alternating current.Skin effect is exactly that electronic current transmits in moving process in the conductor, and electronics, current convergence are in epidermis, the surface portion of conductor.Skin effect be by the fundamental characteristics two like magnetic poles repel each other of electricity, there is a natural attraction between the sexes determine, be also is determined by the free electron of conductor, free electron is also the outermost electron of constituting atom, and atomic nucleus is relatively weak to its attraction, it could freely activity.Conductor is molecular by many atomic buildings.If electronics is at the center of conductor or inner mobile, the nuclear constraint that it will be subject to inner periphery attracts, also can with colliding at the metallic atom doing thermal vibration in dot matrix, and this just hinders the directed movement of electronics.So, also cause the free electron easily movement of conductive surface.We first use seven 1mm ²round naked copper wire do such experiment, compare, look at that what kind of their sectional area and girth there occurs and change and change.If figure is 1 1mm ²round naked copper wire, one, the left side, one, the right, their sectional area and girth are the same, and they allow the maximum current passed through to be 19 peaces separately; Fig. 2 is two 1mm ²round naked copper wire, the left side does not get together, and their sectional area sum and girth sum are all one, Fig. 1 left side 1mm ²2 times of round naked copper wire; On the right of Fig. 2, two is the 1mm tightly got together ²round naked copper wire.Their sectional area sum and the right are the same, are also one, Fig. 1 left side 1mm ²2 times of round naked copper wire, two 1mm on the right of Fig. 2 ²the perimeter of section sum of round naked copper wire be not just one, Fig. 1 left side 1mm ²2 times of round naked copper wire, it is less than a 1mm ²2 times of round naked copper wire because they have had a tangent line to make their girth sum reduce between two.Therefore allow the maximum current passed through neither one, Fig. 1 left side 1mm ²2 times of round naked copper wire.It is less than 2 times; Fig. 3 is three 1mm ²round naked copper wire, the left side does not get together, and the right tightly gets together, and three, left side sectional area and girth sum are one, Fig. 1 left side 1mm respectively ²3 times that justify naked copper wire, the sectional area sum on three, the right is also one, Fig. 1 left side 1mm ²3 times that justify naked copper wire.And the perimeter of section of the three every roots in the right is reduced 1/6, every root only has one, Fig. 1 left side 1mm ²justify 5/6 of naked copper wire girth, so three, the right perimeter of section sum only has one, Fig. 1 left side 1mm ²2.5 times of circle naked copper wire girth, they allow the maximum current passed through also to only have one, Fig. 1 left side 1mm ²justify 2.5 times of naked copper wire.By that analogy, Fig. 4 is 7 1mm ²circle naked copper wire, the left side does not get together, and the right tightly gets together, 7, left side 1mm ²circle naked copper sectional area of wire sum and perimeter of section sum are one, Fig. 1 left side 1mm respectively ²7 times that justify naked copper wire, their allow the maximum current passed through also to be one, Fig. 1 left side 1mm ²7 times that justify naked copper wire, and 7, the right 1mm ²circle naked copper wire cross-section area sum is also Fig. 1 left side 1mm ²7 times that justify naked copper sectional area of wire.7 1mm in the right ²circle naked copper conductor cross-section girth reduces a lot especially, and around 6 every roots reduce 1/3, and perimeter of section only has one, Fig. 1 left side 1mm ²2/3 of circle naked copper wire girth, in the middle of center that root for 7 with together with naked copper wire it does not have outer surface girth, become zero.So 7, the right 1mm ²the perimeter of section of circle naked copper wire only has one, Fig. 1 left side 1mm ²justify 4 times of naked copper conductor cross-section girth, the maximum current that their permissions are passed through i.e. one, Fig. 1 left side 1mm ²justify 4 times of naked copper wire.By this experiment, I finds that conductor allows the maximum current passed through to be ever-increasing along with the increase of the perimeter of section of conductor, and be increase in direct ratio, sum up this to test us and draw such conclusion: at the same temperature, in the uniform conductor that commaterial is made, conductor allows the maximum current passed through to follow the perimeter of section of conductor to be directly proportional.Research and development for more efficiently producing utilization of power electric energy and cable are laid a good foundation by the discovery of this rule and the research of theory.Conductor allows the maximum current passed through to follow its perimeter of section to be directly proportional.This is that (discussion about skin effect can consult Theoretical Physics the 3rd electromagnetism the 217th page to the inevitable outcome produced due to the skin effect of alternating current, Wu great You nineteen eighty-three Science Press publishes, or institution of higher education tries out teaching material electromagnetism volume two the 15th page, Zhao Kaihua, Chen Ximou work, people education publishing house in 1978) skin effect determines by these two aspects of the performance of the person's character of alternating current and conductor.We can also illustrate this problem for some examples.Open rural power handbook (832 pages, table 12-30 polyvinyl chloride wire lays the ampacity under long-term load in atmosphere, core working temperature+65 DEG C, ambient temperature+25 DEG C).0.5mm ²copper cash ampacity be 12.5 peaces, two 0.5mm ²ampacity be exactly 25 peaces, an and 1mm ²copper cash ampacity really only have 19 peaces.Two 0.5mm ²copper cash with a 0.5mm ²copper cash compare, its sectional area adds one times, and its perimeter of section adds one times, so its ampacity also will double, i.e. 25 peaces, an and 1mm ²copper cash with a 0.5mm ²copper cash compare, its sectional area adds one times, but perimeter of section is not increased to one times, thus its ampacity also far below 25 peace, only have 19 peaces; A 1mm ²the ampacity of copper cash be 19 peaces, 4 1mm ²the ampacity of copper cash be 76 peaces.4 1mm ²copper cash with a 1mm ²copper cash compare, its sectional area is increased to 4 times, and its perimeter of section also increases 4 times, so its ampacity also will be increased to 4 times, namely 76 peace.And a 4mm ²copper cash with a 1mm ²copper cash compare, although sectional area increases 4 times, perimeter of section is far from being increased to a 1mm ²4 times of copper cash, so ampacity also far increases less than a 1mm ²4 times of copper cash.I.e. 42 peace.By that analogy, conductor cross-section girth is the key factor determining ampacity.That just idea should expand the perimeter of section increasing it on the basis not increasing sectional area of wire as far as possible, and increase surface area, we still do from most basic single line.When length constant or certain, its perimeter of section is depended in the increase of surface area.At the long-pending round conductor of same cross-sectional with oval wire, the perimeter of section being undoubtedly oval wire is the longest.So oval wire is best selection.Fig. 5 is the comparison of a round enamelled wire and oval enamelled wire cross-sectional view; Be a legend being exaggerated 100 times, the sectional area of circle enamelled wire is equal with the sectional area of oval enamelled wire, and the diameter of section of circle enamelled wire is 0.4mm, and radius is 0.2mm; The major axis A B=0.6mm=2a in the cross section of oval enamelled wire, minor axis a=0.3mm, ratio of semi-minor axis length is (9: 4), and the sectional area and the perimeter of section that calculate them respectively compare; Circle enamelled wire diameter 0.4mm, radius r=0.2mm, area S _circle=r ²π=0.2 ²π=0.04 π mm ².∵ S _circle=r ²π=S _ellipse=π ab ∴ r ²π=π ab ∴ ab=r ²ab=0.04 $\stackrel{\·}{\·\·}a=\frac{0.04}{b},b=\frac{0.04}{a}\underset{\·}{\·\·}\frac{a}{b}=\frac{9}{4}\stackrel{\·}{\·\·}a=\frac{9b}{4},b=\frac{4a}{9}\stackrel{\·}{\·\·}\frac{0.04}{b}=\frac{9b}{4}\stackrel{\·}{\·\·}$ $b=\sqrt{\frac{4\×0.04}{9}}=\frac{2}{15},\stackrel{\·}{\·\·}a=\sqrt{\frac{4\×0.04}{9}}=0.3,$ sectional area with circle enamelled wire is equal. so the perimeter of section of oval enamelled wire has grown 12.5% than the girth of the round enamelled wire of same cross-sectional,

The increase of girth increases the transit passage of just widening and increasing electronic current, improves the efficiency of wire conduct electrical power switching energy.So its electric conductivity also will improve 12.5%.This example sufficient proof of Fig. 5 is when sectional area is identical, oval enamelled wire has the technical characteristic increasing girth than round enamelled wire, the increase of girth, increase its surface area greatly, the increase of surface area is just in time for the skin that becomes of alternating current should create condition, and this just makes the alternating current of skin effect more straightway current.Along with the increase of ellipse long and short shaft ratio, the difference of the girth of the Elliptical Ratio circle of same cross-sectional will be larger.That is oval major axis is longer, and minor axis is shorter, and its girth is longer than the girth of the round enamelled wire of same cross-sectional.Due to the skin effect (kelvin effect) of alternating current, the effective resistance of round conductor is increased, reduces its effective area, thus also reduce its conductive capability.Oval wire has the technical characteristic increasing girth.Compensate for the deficiency of round conductor.Oval enamelled wire it have the effect of increasing section girth, thus expand its surface area, reduce its effective resistance, improve its conductive capability.Ellipse has more good electric property and electric conductivity thus.Core ellipse is cable the most basic the most basic most important essential characteristic.It is the key technical feature of electric wire.Should be familiar with it fully, excavate it, develop it, utilize its characteristic superiority, to make full use of it to save material, save the in vain consumption of electric energy in the line, in equipment, in motor.Benefit future generations all ages.Because the Elliptical Ratio circle enamelled wire that same cross-sectional is amassed has the effect increasing girth, greatly increase its surface area.The increase of surface area, this makes the skin effect of alternating current be fully utilized, thus reduces its effective resistance, improves its electrical efficiency, reduces electric current consume in the line.Improve the quality of voltage, improve the utilance of wire; Because oval enamelled wire is longer than round enamelled wire girth, considerably increase its surface area, due to the increase of surface area, substantially increase again the radiating efficiency of oval wire, oval enamelled wire temperature is reduced, and this adds again its ability to transmit electricity to a certain extent; Because oval enamelled wire is longer than round enamelled wire perimeter of section, substantially increase its conductive capability, if motor transformer and electric equipment are when power output is certain, enamelled wire sectional area can adapt to reduce, and can reduce 5-20% raw material like this; Because oval enamelled wire outer surface is tending towards flat, contact area is large, and the little good wiring of contact resistance, easily welds, not easily loosen, not easily break, be easily wound around, easy moulding, be wound around closely, arrange intensive, make to twine the number of turns in certain wire casing and space more, improve current density, add efficiency.If technique can be widely applied, huge economic benefit and social benefit will be produced in China.Use the most extensive because electric energy is one, the energy resource system that use amount is maximum.Clamor from all generators, transformation, the motor of transportion wire road to all and the energy-conservation process of electric equipment overall process.So not only can save the raw material of much electricity and wire, a lot of fire coals can also be saved, the primary energy of the generating such as fuel oil, also can reduce blowdown heat radiation, reduce environmental pollution, alleviate climate warming.

Summary of the invention

On the basis of the skin effect phenomenon theory of alternating current, particularly under the guidance of the conductor current law theory of alternating current, still there is certain defect in the enamelled wire winding wire lapped wire observing close examination generator, motor, transformation and all power consumption equipments: diameter heavy in section is large, girth is little, it increases the resistance of enamelled wire on the one hand, limit the transit passage of enamelled wire electronic current, reduce enamelled wire conduction conversion efficiency.Particularly round enamelled wire due to girth little, cross section is large, and it not only reduces the transit passage of electronic current, but also reduce the radiating and cooling of enamelled wire, add enamelled wire temperature rise, increase the resistance of enamelled wire, reduce further again the conduction conversion usefulness of enamelled wire.

A large-scale generating set, its electric power supply of relating to huge numbers of families of large-scale transformer even relates to the supply of the electric power of a city or a region.If again can improve this great scientific and technological behave beyond doubt of efficiency of the production electric energy converting electrical energy of generator transformer, we have been proposed the energy-efficient enamelled wire of a special type, i.e. oval enamelled wire.Current law according to conductor: conductor allows that the maximum current passed through follows the perimeter of section of conductor to be directly proportional.Oval enamelled wire has the technical characteristic than same cross-sectional circle enamelled wire increasing section girth.The increase of girth increases meaning increases the transit passage increasing and broaden electronic current.Which reduce resistance, improve the functional efficiency of the wire conduction conversion energy.For metallic conductor, because the increase of the perimeter of section of conductor increases, increase the surface area of conductor, the increase of surface area increases the ventilation and heat efficiency that just improve conductor.Thus reduce conductor temperature.The reduction of temperature turn reduces the resistance of conductor, and it just further improves the efficiency of the conduction conversion energy of conductor.If we want the efficiency continuing raising or perhaps raising generator transformer motor by a larger margin.Just can adopt the enamel-cover multichannel parallel energy-conservation enameled electric wires of parallel assembled highly-effective side by side.It comprises the oval enamel-cover multichannel parallel energy-conservation enameled electric wires of parallel assembled highly-effective side by side; Circle enamel-cover multichannel is the parallel energy-conservation enameled electric wires of parallel assembled highly-effective and oblate (lenticular wire) enamel-cover multichannel type such as the parallel energy-conservation enameled electric wires of parallel assembled highly-effective side by side side by side.It in fact mainly utilizes undergauge extraneous root to increase the product of the method for the perimeter of section of enamelled wire, and it increases the technical method of girth and the technical method of the parallel parallel squeezed tight of layering from inside to outside adhered arrangement arranged side by side containing having covered insulation isolation.Because what we related to is all multichannel many conductor wire cores is all the conductor wire core of separate conductive, if they are wound around mutually stranded, every root single line core will form a helix tube core, will produce very large inductance, produce magnetic field, hinder the circulation of electric current to produce impedance.So just must emphasize the arrangement mode of parallel parallel side-by-side, it is also a kind of well technical scheme concerning the wire be combined into by multichannel many conductor wire cores.It is minimum that it can make inductive impedance drop to.If the thin single line core that undergauge extraneous root increases girth is oval core, it is just containing having covered oval growth method, if the thin single line core that undergauge extraneous root increases girth is square, rectangle, oblate core, it is just containing having covered square, rectangle, oblate growth method.

Because round conductor is that in the various wires of various same cross-sectional different cross section shape, girth is minimum the shortest.So the technical method that we utilize undergauge extraneous root to increase girth transforms generator of the prior art, motor, the basic wire enamelled wire of transformer and all power consumption equipments, electromagnetic wire lapped wire winding wire, by the thick enamelled wire winding wire of single single core of the prior art by undergauge extraneous root become two or the fine enamelled wire winding core of many, make total sectional area of the fine enamelled wire winding wire of many equal with the sectional area of the thick enamelled wire winding wire of single single core, although total sectional area of the fine enamelled wire winding wire of many is equal with the thick enamelled wire winding wire sectional area of single single core, but the girth of the fine enamelled wire winding wire of many really adds a lot than the girth of the thick enamelled wire winding wire of single single core, it is more that thin wire radical increases, its total perimeter of section is more with regard to what increase.The increase of total perimeter of section increases, and just adds the transit passage increasing and broaden and increase electronic current.The increase of perimeter of section increases the all-in resistance also reducing the assemble line be made up of many fine rule cores, improves conduction translation function and the efficiency of combination enamelled wire winding wire.Combine for by many multichannel fine rule cores the enameled conducting wire formed, the textural association of the parallel side-by-side parallel of winding conducting wire layering squeezed tight bonding is from inside to outside a kind of well technical scheme.To ensureing that the length of each root list enamel-cover core is consistent, resistance is equal, and the electric current and voltage of conversion is equal identical very important, can not mutually be wound around stranded.If the basic single line core after undergauge extraneous root is round enamelled wire, adopt two, four, seven ... it is very suitable to combine, because the fundamental figure of the cross section of the compositions such as two, four, seven is flat, square and circular, be convenient to winding roll off the production line, arrangement close clearance is between the lines reduced, increases the density of wire; If the basic single line core after undergauge extraneous root is ellipse enamelled wire, adopt two, four, seven, nine ... very suitable, because the fundamental figure of the cross sections be combined into such as two, four, seven, nine is the shape of flat, square, rhombus, easily make the tight intensive winding of coil, make arrange closely between the lines.If it is square, rectangle, flat oblateness that undergauge increases the basic single line core extremely, adopt two four ... comparatively suitable.Because the fundamental figure of the cross section of the compositions such as two, four is rectangle, square shape, making carefully to enclose between wire can tight intensive windings arrangement, and make gap between the lines little, arrangement is tight.Manufacture or use undergauge extraneous root parallel parallel combination enamelled wire is all more equal with former slightly single cross section by its total cross section of designing and calculating side by side theoretically.The efficiency of the many fine enamelled wire conduct electrical power conversion energy can improve much exactly.Manufacture enamel-cover many multichannels side by side parallel parallel assembled highly-effective energy-conservation enameled conducting wire time first should calculate and design and manufacture required various cross sectional shape and the long-pending thin single line core of section of diameter, then first after slender core spray insulation paint baking airing, they are become the thin single line core of enamel-cover.Again need arranged side by side parallel of many slender enamel-cover cores or parallelly toast airing by inner layering squeezed tight outward together.If want that carefully two spray insulation paints also can directly complete with parallel bonding by circle, the parallel combination of thin oval single line core together two.Because the tack of insulating varnish and adhesiveness are very strong.Even if two thin single line core close contacts also can not have too much influence by the perimeter of section total to these two thin single line cores.If you are by calculating design with thin single enamelled wire of two or many and to be coiled into coil to replace single thick enamelled wire be also completely passable, it directly applies a kind of method that undergauge extraneous root increases the perimeter of section of enameled conducting wire, it should be noted and will make many equal laid out in parallel of fine enamelled wire length, arranged in parallel, be not wound around mutually, it is difficult to accomplish for tight ordered arrangement mode in addition, if breaking down in motor transformation local causes certain difficulty to maintenance.Or the energy-efficient enameled conducting wire of enamel-cover multichannel the parallel combined arranged side by side is even better.

The cross-sectional view of Fig. 6 to be a diameter be round copper enamelled wire of 4mm.So, its sectional area and girth respectively: S=r ²π=2 ²π=4 π mm ², π=4, l=2r π=2 × 2 π mm.The cross-sectional view of Fig. 7 to be four diameters be round copper enamelled wire of 2mm.Its sectional area and total perimeter of section be respectively: S ₄=4r ²π=4 × 1 ²π=4 π mm ², l _four=42r π=4 × 2 × 1 × π=8 π mm.Although the sectional area that cross-sectional area and a diameter that four diameters are the round copper enamelled wire of 2mm are the round copper enamelled wire of 4mm is equal, the girth of four diameters to be the girth of the round enamelled wire of 2mm than a diameter be really round copper enamelled wire of 4mm adds one times.This just means that Fig. 7 tetra-diameters are the electronic current of the round copper enamelled wire of 2mm, the transit passage circulated is that the transit passage of the electronic current of the round copper enamelled wire of 4mm broadens one times than Fig. 6 diameter, Fig. 7 tetra-diameters are that the resistance of the round copper enamelled wire of 2mm is also little one times than the resistance of the round copper enamelled wire of Fig. 6 diameter 4mm, and Fig. 7 will double than the functional efficiency of Fig. 6 circle copper enamelled wire conduct electrical power conversion energy.If the diameter continuing to reduce enamelled wire increases the radical of basic core, it is more that its total cross section girth will increase, ten six roots of sensation diameters be the sectional area of the round copper enamelled wire of 1mm and girth respectively: S ₁₆=16 × r ²π=16 × 0.5 ²π=4 π mm ², l ₁₆π=16 ,=16 × 2r π=16 × 2 × 0.5 π mm, 16 diameters are the round copper enamelled wire of 1mm is equal with the cross-sectional area that 1 diameter is the round copper enamelled wire of 4mm, if their length is equal, their volume is also just equal.But the girth that the perimeter of section that 16 diameters are the round copper enamelled wire of 1mm is really the round copper enamelled wire of 4mm than a diameter increases 4 times.The increase at double of its girth increases, and increases the transit passage broadening and add electronic current greatly.Reduce greatly after undergauge extraneous root by total resistance of ten six roots of sensation carefully round copper enamelled wire, greatly increase the transmission conduct electrical power conversion energy functional efficiency of enamel-cover multichannel parallel parallel combination enamelled wire side by side.Current law according to conductor: conductor allows that the maximum current passed through follows the perimeter of section of conductor to be directly proportional.Conductor allows that the maximum current passed through is determined by the girth of conductor, and the girth of conductor is less, and it allows that the maximum current passed through is less, and the girth of conductor is larger, and it allows that the maximum current passed through is larger, and is directly proportional increase.It is the method increasing in Zhou Changfa the most the highest the best of prevalent effects that undergauge extraneous root increases the method for girth, the application that it walks abreast in parallel combination enamelled wire side by side in enamel-cover multichannel, the girth of enamel-cover multidiameter delay assembled highly-effective energy-saving paint envelope curve will be increased widely, greatly improve the functional efficiency of enamelled wire.It brings unprecedented historical revolution to change will to the manufacture of generator, motor, transformer and all power consumption equipments.My basic conception is still wanted to improve all wires.The output line that electricity is transported to step-up transformer is sent from the winding wire of generator to generator, copper, aluminium stranded conductor from the enamelled wire of first and second coil of step-up transformer to high-pressure delivery, arrive again two of transformer station's step-down transformer, secondary coil, arrive again the distribution transformer of each factories and miness user, then be transported to workshop, the electric wire of user, cable to the omnidistance reformed AHP of enamelled wire of motor, equipment.If this brand-new section technical ability is applied in the whole nation, all parts of the world.The new way that mankind's (generating power transmission and transformation distribution, motor, electric equipment and all power consumption equipments) are energy-efficient will be opened up.Start new era that the mankind are energy-conservation, economize on electricity.This ground-breaking innovation and creation really.It is a directivity, and it is a kind of approach of a road.The developing innovation and creation of a territoriality.It, to the economic development close relation of China and even the people of the world and impetus gravely, involves the interests of the state and the people, relation country vital interests.Also be physical once great discovery simultaneously.Make the development from now on of electric wire, cable winding wire have a clear and definite direction, there is great economic benefit and social benefit.

Embodiment

Because alternating current movement conduction in conductor has skin effect, the result of skin effect increases its effective resistance, reduces the utilance of the effective cross-section of alternating current in round conductor, reduces the transfer passage of alternating current in conductor.Increase the resistance of wire.Limit the current of some electronics.The skin effect of alternating current is more and more similar to our automobile on the run on a highway, but it to be a three-dimensional surface pass through.And automobile be on a highway a plane truly pass through.If we are the unfolded surface of conductor, it is exactly a very thin very long rectangular electronic highway.If expressway widening is increased track, the automobile that nature can pass through is more.Wire is the high speed runway of electronics, do we really add wide multiple spot to it? circle enamelled wire is compared with oval enamelled wire, if surface area is identical, the volume of circle enamelled wire is greater than the volume of oval enamelled wire.If the oval enamelled wire that sectional area is identical compares with the round enamelled wire that sectional area is identical, the girth in oval enamelled wire cross section is greater than the girth in round enamelled wire cross section, onesize sectional area, and oval enamelled wire has the technical characteristic increasing girth than round enamelled wire.The increase of oval enamelled wire girth means the three-dimensional runway broadening electronics.This is how similar with automobile on the run on highway! Reason is identical, I thinks the best way realizing this invention, that insulation isolation is increased Zhou Changfa, oval increase Zhou Changfa, undergauge extraneous root increase Zhou Changfa and the straight line side by side parallel method integrated use best results reducing inductance by the inner squeezed tight of layering outward glued construction combination arranged in parallel are preferably the highest.Particularly the method for undergauge extraneous root has more the most significant the most outstanding effect.Embodiment 1, Fig. 8 is a 7mm ²the cross-sectional view of round copper enamelled wire.So

L _{7 circles}÷ l _greatly=24.8143539123 ÷ 9.3789441996=2.64575131104 doubly.Figure 10 is seven 1mm ²the cross-sectional view of oval copper enamelled wire, the ratio of ellipse long and short shaft is 9: 4, so the cross section of each root ellipse of Figure 10 is: r ²π=π ab=1 ∵ π ab=1, ∵ a: b=9: 4 ∴ 4a=qb $\stackrel{\·}{\·\·}a=\frac{qb}{4},b=\frac{4a}{q},$ $\stackrel{\·}{\·\·}\frac{1}{\mathrm{\π}b}=\frac{qb}{4}\stackrel{\·}{\·\·}b=\sqrt{\frac{4}{9\mathrm{\π}}}=0.37612638902\stackrel{\·}{\·\·}\frac{1}{\mathrm{\π}a}=\frac{4a}{q}\stackrel{\·}{\·\·}4{\mathrm{\πa}}^2=9\stackrel{\·}{\·\·}a=\sqrt{\frac{9}{4\mathrm{\π}}}=0.84628437531$

So the perimeter of section of the oval enamelled wire of each root of Figure 10 so Figure 10 seven 1mm ²total perimeter of section of oval copper enamelled wire, l _{7 is ellipse}=4.05085301757 × 7=28.3559711229mm,

so Figure 10 seven 1mm ²total perimeter of section of oval copper enamelled wire than Fig. 9 seven 1mm ²total perimeter of section of round copper enamelled wire add 14.3% girth.

L _{7 is ellipse}÷ l _greatly=28.3559711229 ÷ 9.3789441996=3.02336494592 doubly.By undergauge extraneous root, by a 7mm ²round copper enamelled wire become 7 1mm ²round copper enamelled wire, its perimeter of section is just increased to a 7mm ²3.02336494592 times of round copper enamelled wire girth.The perimeter of section of the significant raising wire that undergauge extraneous root can significantly be given prominence to especially, it is the method for the raising wire girth that the highest effect of a kind of effect is the most outstanding.If seven of undergauge extraneous root 1mm ²round copper enamelled wire change seven 1mm into ²oval enamelled wire, and make its ratio of semi-minor axis length be 9: 4.It just improves total perimeter of section of enamelled wire more, and it just can bring up to a 7mm ²3.02336494592 times of round copper enamelled wire girth.Current law according to conductor: because conductor allows that the maximum current passed through follows the perimeter of section of conductor to be directly proportional.The size of the girth of sectional area of wire determines that the factor determined by the key factor of maximum current size allowed by wire.So the size of the girth of enamelled wire determines that the decisive factor by maximum current allowed by enamelled wire.The increase greatly of the girth of enamelled wire, just broadens the transit passage adding the electronic current increasing enamelled wire widely.Reduce the resistance of enamelled wire, greatly increase the functional efficiency of the enamelled wire conduct electrical power conversion energy.Walk abreast side by side in the manufacture process of parallel assembled highly-effective energy-saving paint envelope curve at enamel-cover multichannel straight line, although we did not specially propose the method for isolating and increasing girth that insulate, but in whole manufacture process all in the method using insulation isolation, because the inherently enamelled wire of our research, so the core of fine enamelled wire core in any case after undergauge extraneous root necessarily enamel-cover.This just means that it is insulation isolation.This is a self-evident problem.

Although we manufacture the thin circle of undergauge extraneous root, thin oval enamel-cover core complete.Their permutation and combination structure is also a technical scheme: their core with must be that straight line parallel parallel that tightly get together or from inside to outside the tight honey of layering arranged side by side that insulate bonds and extrudes being arranged to form of being integrated between core.The function of guarantee every root single line core and efficiency.It twists together formation unlike the naked twisted conductor cable of single core.Because their each root single line cores are all wires of separate conductive.Stranded winding will form toroidal winding and produce inductance mutual inductance, and the induction reactance increasing every root single line core hinders the current circulation of electronic current.Reduce conduction translation function and the efficiency of overall enamelled wire.So want the linear array that straight line parallel arranges, walks abreast side by side, and be bonded together closely.Reduce the induction reactance of enamelled wire as far as possible, and force them to bond adult closely by means of the adhesiveness of insulating varnish, also corrosive adhesive can not had to make them be bonded into a multicore enamel insulated wire to insulating varnish with other.Improve the allomeric function of enamelled wire.Improve the functional efficiency of the conduct electrical power conversion energy of enamelled wire.Powerful effect of the energy-efficient enamelled wire closely combined of enamel-cover multidiameter delay side-by-side parallel.Manufacture most important for generator, motor, transformer and all power consumption equipments.It is regenerated to electrical equipment and electrical renewal of the equipment, saves material to raise the efficiency and it is produced effective transmission to the cheapness of electric energy and utilizes and produce historical change.There is great economic benefit and social benefit.There is great environment protection significance.
