Background of the invention

1. Field of the invention

The present invention relates to a high conductivity wire having improved electrical conductivity and a manufacturing method thereof.

2. Description of the Related Art

Any form of energy used by consumers goes through different states, including the production or collection, transportation, storage, transformation or transformation into a more appropriate form and consumption. In the transition from one phase to another, energy loss inevitably occurs from a few percent to a few tens of percent. According to the law of entropy, energy is gradually transformed into an unusable low-quality form (eg, heat) that is distributed in space, causing energy loss as well as environmental pollution.

Electrical energy is also lost during generation, conversion and transportation from one point to another point in space, minimizing this loss is very important in terms of cost reduction and environmental protection.

Electrical conductivity is a factor in the transmission of electrical energy. The electrical conductivity is a measure of the ability of an electrical conductor (eg, an electrical wire) to conduct an electrical current. If the electrical conductivity is high, the electric current flows well; on the other hand, when the electric conductivity is low, the electric current is poorly flowing. The electrical conductivity can be expressed as the reciprocal of the electrical resistance. The electrical conductivity L of an electrical conductor can therefore be expressed by the following equation:

As can be seen from the above equation, the electrical conductivity L of an electrical conductor depends on a length l, a cross-sectional area S, and an electrical resistance ρ of the electrical conductor.

Super conductivity is an example of a phenomenon that causes a change in the electrical resistance ρ. Super conductivity is a phenomenon in which the electrical resistance of a metal or alloy becomes zero when the metal or alloy is cooled to a temperature close to 0K (-273.16 ° C). Recently, high pressure has been made in the field of super conductivity phenomenon. In particular, research is being conducted extensively on superconductive materials that may be superconducting at relatively high temperatures, a superconductivity phenomenon produced by conductors having relatively high critical temperatures, etc. However, superconductive materials are subject to a variety of limitations in their widespread use They still need to be cooled down to a relatively low temperature to show a superconducting phenomenon.

On the other hand, the electrical conductivity of a lead wire may be affected by the length or thickness of the lead wire. However, the electrical conductivity of a wire after the production of the lead wire is no longer changeable.

Detailed description of the invention

The present invention will be described in more detail below with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. Although, for ease of description, a line through which current flows is referred to as a wire and an arrangement in which wires are wound is referred to as an electric wire, the invention is not limited thereto. In addition, in the drawings, the thickness or size of each layer is exaggerated, omitted or schematically illustrated for ease of description and clarity.

The 1A to 1F show a method for producing a high conductivity electric wire (hereinafter referred to as "electric wire") according to an embodiment of the present invention. 2 FIG. 12 is a diagram showing a configuration of an electric wire manufactured according to an embodiment of the present invention. FIG. 3 shows a sectional view along a line aa 'in 2 , In the present embodiment, a method of manufacturing an electric wire by winding five lead wires will be described.

The five lead wires according to the present embodiments may be arranged side by side. The lead wires may each be a wire clad with an insulating material. For example, one or more of the lead wires, for. B. a lead wire 3 be a blind wire in which no current flows. Also, you can use a conductor wire 1 and a lead wire 2 on the left side of 1A positive wires (+), and a lead wire 4 and a conductor wire 5 on the right side of 1A can be negative wires (-).

The lead wires may be made of a metal such as copper, silver, gold, aluminum or an alloy thereof. A dummy wire may consist of a conductor, an insulator, a semiconductor or a flammable material. When a dummy wire is formed of a flammable material, the flammable material may be burned to remove the dummy wire. The lead wires may each have the same thickness or different thicknesses.

A method of winding the five lead wires may be as follows:
First, the left most lead wire is over the lead wires 2 and 3 guided and between the wires 3 and 4 arranged.

Second is the rightmost lead wire 5 over the wires 4 and 1 guided and between the wires 3 and 1 arranged.

Third is the leftmost lead wire 2 over the wires 3 and 5 guided and between the wires 5 and 1 arranged.

Fourth, the rightmost lead wire becomes 4 over the wires 1 and 2 guided and between the wires 2 and 5 arranged.

Fifth, the leftmost lead wire 3 over the wires 5 and 4 guided and between the wires 4 and 2 arranged.

That is, the process described above repeats the positioning of either the rightmost or leftmost lead wire in the middle of the other four wires.

When the lead wires are wound according to the methods described above, the lead wires from the left side become in the decreasing row 5 . 4 . 3 . 2 and 1 , as in 1F shown, arranged. This means that the order of the wires is reversed.

When the process is repeated again, the lead wires may be in increasing order 1 . 2 . 3 . 4 and 5 be arranged, which corresponds to the original arrangement. That is, by winding the lead wires as described above, the plurality of lead wires may have a regularly wound shape as in FIG 2 and the plurality of lead wires have a three-dimensionally wound shape as in FIG 3 shown. The arrangement of the lead wires can be repeated periodically by the uniform winding. In the formation of the wound form, the lead wires may be formed to cross each other. This shows 3 a cross section along a line aa 'the 2 However, the embodiments are not limited to the shape of the cross section of 3 limited. That is, the shape of the cross section may vary depending on the arrangement of the cross section.

The present invention has been described with the inclusion of a dummy wire, however, the embodiments are not limited thereto. For example, the electric wire may also be formed only of lead wires in which current flows. Even if the electric wire contains a dummy wire, the dummy wire can be removed later.

On the other hand, terminals at both ends of the electric wire may include a positive terminal and a negative terminal. In the present embodiment, the positive terminal and the negative terminal may each comprise two lead wires. The number of lead wires included in the respective terminals may vary depending on the lead wires contained in the electric wire. However, the number of lead wires included in each terminal must be equal to each other. If the number of lead wires in the electric wire is odd, the number of dummy wires may be odd.

As described above, five lead wires in different shapes have been three-dimensionally wound, however, the present embodiment is not limited thereto, and three or more lead wires may be three-dimensionally wound. In addition, the wound lead wires can maintain a constant distance from each other while crossing each other. Therefore, the electrical conductivity of the electric wire can be increased and its resistance can be reduced, whereby the efficiency of power transmission can be maximized.

Experimental data of the conductivity detected using a high conductivity electric wire according to an embodiment of the present invention are described in Table 1. input voltage 2 mm copper wire (single wire) 2 mm copper wire (four wires) Wire according to an executionshowsform (2 mm kander wire, five wires (one blind wire)) 12V 2.3 A, 27.6 W 12A, 144W 14.3 A, 171.6 W 24V 2.9 A, 69.6 W 12.4 A, 297.6 W 15.2 A, 364.8 W Table 1

Data acquisition was performed using a digital multimeter from Rhode & Sehwarts Inc.

The following steps were all performed under the same conditions. When a voltage of about 12 V was applied to an input terminal of a copper wire having a diameter of about 2 mm, a current of about 2.3 A flowed in the copper wire. With four wires of copper wires, a current of about 12 A flowed through them. On the other hand, when an electric wire according to the embodiment of the present invention was charged with 12 V, a current of about 14.3 A flowed. According to the present embodiment, five wires were used, and one of the five wires could be a dummy wire in which no current flows. The blind wire can be used to adjust the distance between the wires.

When a voltage of 24 V was applied to the input terminal of the copper wire with a diameter of about 2 mm, a current of about 2.9 A flowed through it. With four wires of copper wires, a current of about 12.4 A, about four times as large as 2.9 A, flowed. On the other hand, when 24 V was applied to the electric wire according to the embodiment of the present invention, a current of about 15.2 A flowed this. All electrical wires used here were disguised electrical wires. The port included two input ports and two output ports. The terminals were each formed by connecting two of the four electric wires.

As shown in Table 1, when an electric wire according to the embodiment of the present invention is used, the electric conductivity can be increased by 19% to 21% as compared with a conventional method.

As described above, when an electric wire according to an embodiment of the present invention is used, the electrical conductivity of the electric wire may be increased. Accordingly, the current can flow more easily, and the power consumed by the electric wire can be reduced due to a low resistance, thereby enabling a more efficient power transmission.

Although the electric wire has been described as winding five lead wires, the embodiments are not limited thereto. That is, the number of lead wires and the number of dummy wires included therein can be varied variably.

4 shows a configuration of a wire made according to another embodiment of the present invention. The 5A and 5B are sectional views along lines bb 'and cc' of 4 ,

Referring to 4 For example, the electric wire according to the present embodiment may include three lead wires (hereinafter referred to as "ground core wires"). 12 to 14 include. The electric wire can further two lead wires 11 and 15 in a particular pattern.

The three Grundachsendrähte 12 to 14 can be spaced from each other at a certain distance. The baseline wires 12 to 14 of the 4 have been shown arranged in a straight line, but may also be arranged three-dimensionally. For example, the cross sections of the Grundachsendrähte 12 to 14 have a polygonal shape, for example triangular.

The distances between the Grundachsendrähte 12 to 14 can be about twenty times the thickness of the baseline wires 12 to 14 correspond. The baseline wires 12 to 14 can be covered with an insulating material.

The two additional wires 11 and 15 may be formed to a three-dimensional and uniformly wound pattern with respect to the Grundachsendrähte 12 to 14 exhibit. In the present embodiment, the two additional lead wires 11 and 15 be arranged so as not to cross each other, however, the embodiments are not limited thereto. The two additional wires 11 and 15 can cross each other.

The additional wires 11 and 15 may be made of a metal such as copper, silver, gold, aluminum or an alloy thereof. The additional lead wires may be coated with an insulating material.

Each of the basic axis wires 12 to 14 or the additional lead wires 11 and 15 can be a blind wire. The blind wire may consist of a conductor, an insulator, a semiconductor or a flammable material. If a blind wire is formed of a flammable material, the flammable material may also be burned to remove the blind wire. The baseline wires 12 to 14 or the additional wires 11 and 15 may have the same thickness or different thicknesses.

Looking at the cross sections along the lines bb 'and cc' in the 5A and 5B , the basic axis wires can 12 to 14 and the additional wires 11 and 15 which are wound around the same, be arranged in three dimensions.

Although three basic axis wires have been described as being present in the present embodiment, the embodiment is not limited thereto. For example, it is possible to form an electric wire using two or more fundamental axes wires. In addition, when three or more ground-axis wires are used, the ground-axis wires may be formed on a straight line or in a three-dimensional pattern. Here, the three-dimensional pattern means that the cross sections of the fundamental axes instead of the straight line have different patterns, such as a circle, an oval, a polygon, the number eight (∞) or a peanut shape.

Terminals at both ends of the electrical wire may include two terminals, that is, a positive terminal (+) and a negative terminal (-). The terminals may comprise a ground wire as well as a bundle of lead wires wound therearound. Each of the terminals may comprise half of all the wires present in the electrical wire. For example, if two ground wires and two additional wires are provided, the positive terminal may comprise a bundle of one ground wire and one additional wire, and the negative terminal may comprise a bundle of the other ground wire and the other wire. If three fundamental wires and two additional wires are provided, the positive and negative terminals may each comprise a ground wire and an additional wire. The remaining ground wire may be a blind wire.

In addition, when the formation of the ground-core wires and the additional lead wires wound therearound is completed, the electric wire may be coated with a plastic or rubber to maintain the shape of the electric wire.

The formation of the ground core wires and the additional lead wires wound around them may increase the electrical conductivity of the electric wire and may allow a current to flow more easily in the electrical wire. That is, it is possible to reduce the power consumed in the electric wire and to transport power more efficiently by reducing the resistance of the electric wire.

The theoretical background for improving the conduction transfer efficiency by winding individual electric wires in an electric wire is based on concepts such as Maxwell's equations, harmonic oscillations and power factor theories, the presence of a maximum allowable value and the saturation capacity of a transmission line according to a power generation source and the electromagnetic interaction of current carrying wires ,

Harmonic oscillations are periodically repeated waveforms that can be reduced to a sine wave that has a fundamental frequency and sinusoidal vibrations that have frequencies that are integer multiples of the fundamental frequency. In this case, the harmonic vibrations may refer to sine waves that have no fundamental vibration. For example, a vibration having a frequency of n times the fundamental frequency may be called an nth order vibration. In the case of noises, the vibrations may correspond to harmonics and may be used in electrical vibrations, electromagnetic waves and the like. The vibrations may also be referred to as second or third harmonic oscillations according to the multiple of the fundamental frequency. When a vibration is a modified vibration and not a sine vibration, the vibration may include a harmonic vibration. For example, the tones of a musical instrument may vary with contained harmonic vibrations.

The power factor refers to a ratio of active power to apparent power in an alternating current (AC) circuit. While the electric power is expressed as the product of the voltage and the current in the direct current (DC) circuit, the product of the current and the effective value (RMS) does not necessarily become the electric power in the AC circuit. In an AC circuit, the product of voltage and current is called apparent power. Electrical power can be obtained by multiplying the pigtail by the power factor. This is because the current and voltage of the AC circuit are changed to sinusoidal, and the phases of the two sinusoids are not necessarily coincident with each other. The active power can be expressed as V Icos Φ, where Φ is a difference in the phase angle, V is a voltage, and I is a current. Since the apparent power is equal to VI, the power factor can be expressed as VIcos Φ / VI = cos Φ, active power divided by apparent power, and can generally be represented as a percentage. If Φ = 0, cos Φ equals 1 represents the maximum amount of electric power. That is, the power factor ranges from 0 to 1. When electrical energy is converted into thermal energy by, for example, an electric heater or an incandescent lamp, the Power Factor 1. However, if a portion of a current flowing in an iron core of an AC power generator generates a magnetic current to magnetically store energy, such as a motor or transformer with an iron core, or if energy is stored electrostatically, for example a capacitor, the power factor can be reduced. A low power factor may be referred to as a poor power factor.

A current flows through an electric wire when electricity is generated. A magnetic field is created around the wire in which the current flows. In an electric wire having a plurality of lead wires, unlike an electric wire having only a single lead wire, the lead wires may be influenced by magnetic fields generated by current flowing in adjacent lead wires. The flow direction of the stream, d. H. the direction of the lead wires may have an effect on the direction of the magnetic field and may further have an effect on the currents in other lead wires, more specifically on the movement (moving speed) of the electric charges. This means that the phases of the currents flowing in the lead wires are affected, resulting in variations of the power factor.

In other words, when the plurality of lead wires are three-dimensionally wound to form an electric wire, the interaction between magnetic fields generated in the respective lead wires can facilitate the movement of the electric charge in the lead wires and thereby increase the electrical conductivity.

On the other hand, the high-conductivity wire according to an embodiment of the present invention can be applied particularly favorably to photovoltaic power generators such as silicon solar cells, thin-film solar cells, dye-sensitized solar cells and organic solar cells, microbial power generators and fuel cell generators become.

For example, when the electric power generated by a photovoltaic power generator is transmitted to storage batteries via electric wires according to the embodiments of the present invention, the electricity generated in the solar cell can be more efficiently transported to the storage batteries.

In a photovoltaic power generator, carriers generated by irradiating a p-n compound material with sunlight can be stored. In this case, due to the irradiation with sunlight, the number of carriers in the p-n compound material increases, thereby lowering the generation efficiency of the carriers. Accordingly, it is necessary to discharge the generated carriers faster to the outside. However, the speed of movement, that is, the drift velocity of the free electrons, the carrier is very low (eg, a movement of about one meter takes about one hour and ten minutes). Therefore, it is expected that the electric wire according to the embodiment of the present invention accelerates the movement of the electrons according to various theories described above, and therefore increases the power generation efficiency by rapidly removing newly generated carriers in the p-n compound material.

The power generation regions described above are merely examples. Accordingly, the present invention can be applied to all areas of power generation whose power generation efficiency can be improved by facilitating the movement of electric charges.

While the invention has been particularly shown and described with reference to exemplary embodiments, it will be apparent to those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the present invention as defined in the following claims.
