Description

[0001] APPARATUS FOR ENHANCING POWER EFFICIENCY [0002]

The present invention relates to a power efficiency improving device capable of improving conductivity of a conductor and reducing heat loss due to resistance.

Due to the delay in the development of environmentally friendly alternative energy technologies, the energy shortage is a common problem all over the world. In order to solve the energy shortage, 1) environmentally friendly alternative energy and 2) high efficiency power device have been developed. In addition, recently, interest in improving the efficiency of the electric device through external devices has increased .

However, the circuit technology that maintains the waveform of the alternating current supplied by the electric power facility is a help to improve the efficiency of the electric device, but it can not be a solution to the fundamental improvement of the electric device efficiency. The reason for this is that the main factor that deteriorates the efficiency of the electric device is the random motion of the free electrons advancing in the conductor and therefore the collision with other atomic oscillation motions. Therefore, in order to improve the efficiency of the electric device, it is considered to arrange the free electrons of the random motion in a predetermined direction to reduce the probability of collision with other atoms or free electrons, thereby increasing the drift velocity of the free electrons .

Referring to FIGS. 1 and 2, a power efficiency improving apparatus 200 according to an embodiment of the present invention will be described. FIG. 1 is a block diagram of a power efficiency improvement apparatus 200 according to an embodiment of the present invention, and FIG. 2 is a perspective view of a magnetic field generator 210 of FIG. 1 according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the power efficiency improving apparatus 200 may be connected in parallel to the power line 120 between the power source unit 100 and the load unit 110. The power supply unit 100 supplies power to the load unit 110 and the load unit 110 operates by receiving power from the power supply unit 100. The load section 110 may be any device that uses electric power such as, for example, production facilities, machinery, buildings, and the like.

The power line 120 connects the power source unit 100 and the load unit 110 and supplies power to the load unit 110. An AC voltage may be applied to the power line 120. The power line 120 may include first to fourth power lines 121, 123, 125, and 127. The first to fourth power lines 121, 123, 125, and 127 have the same voltage and may have different phases. 1, the power line 120 is three-phase four-wire and includes four power lines 121, 123, 125 and 127. However, the present invention is not limited thereto. For example, the power line 120 ) Is a three-phase three-wire wire, and may include three power lines, and may be a four-phase wire other than the three-phase wire.

The power efficiency improving apparatus 200 may include a magnetic field generating unit 210, a lead wire 220, and a control unit 230.

The magnetic field generating unit 210 generates a strong magnetic field. The generated magnetic field may increase the flow rate of free electrons in the power line 120 and the power lines disposed in the load section 110 to improve the conductivity of the power line 120 and the conductors disposed in the load section 110.

The magnetic field generating section 210 can generate a magnetic field of 0.1T to 1T. A magnetic field less than 0.1T is somewhat insufficient to improve the power efficiency of the load section 110, and a magnetic field exceeding 1T is not easy to generate. In addition, the greater the intensity of the magnetic field, the lower the conductivity of the conductor and the shorter the life expectancy of the magnetic field generator 210.

The wire 220 is necessary to have a magnetic field effect on the load 110 and the power line 120. One end of the lead 220 is connected to the power line 120 and the other end of the lead 220 is connected to the control unit 230. The conductor 220 is not directly connected to the magnetic field generator 210 and passes through the magnetic field generated by the magnetic field generator 210.

The control unit 230 is connected to the other end of the lead wire 220. The control unit 230 can control the voltage and current flowing through the wire 220. Specifically, the control unit 230 may apply an AC voltage identical to the AC voltage applied to the power line 120 to the conductor 220, thereby preventing the overcurrent of the conductor 220.

The number of the magnetic field generator 210 and the number of the wires 220 may correspond to the number of the power lines 120. For example, when four power lines 120 are used, four magnetic field generators 210 and four conductors 220 may be used. The magnetic field generator 210 is also provided with four power lines 121, 123, 125, and 127 corresponding to the power lines 121 and 123, and the power line 120 is also connected to each power line 121 , 123, 125, 127). Specifically, one end of the first sub-conductor 221 is connected to the first power line 121, the first sub-conductor 221 passes through the magnetic field generated by the first magnetic field generator 241, The other end of the lead 221 may be connected to the control unit 230. One end of the second sub-conductor 223 is connected to the second power line 123, the second sub-conductor 223 passes through the magnetic field generated by the second magnetic field generator 243, and the second sub- May be connected to the control unit 230. One end of the third sub lead 225 is connected to the third power line 125 and the third sub lead 225 passes through the magnetic field generated by the third magnetic field generator 245 and the third sub lead 225 May be connected to the control unit 230. One end of the fourth sub-conductor 227 is connected to the fourth power line 127, the fourth sub-conductor 227 passes through the magnetic field generated by the fourth magnetic field generator 247, and the fourth sub-conductor 227 May be connected to the control unit 230.

The magnetic field generator 210 will be described with reference to FIG. In FIG. 1, four magnetic field generators 241, 243, 245, and 247 are illustrated. Since four magnetic field generators 241, 243, 245, and 247 have the same shape, they will be described only once.

The magnetic field generating unit 210 may include a magnetic body 310 and a fixing unit 330. The magnetic body 310 can generate a strong magnetic field 320. [ The magnetic body 310 can generate the magnetic field 320 having a size of 0.1T to 1T. Although the magnetic body 310 is shown as being circular, the present invention is not limited thereto.

The fixing portion 330 may be disposed between the conductive plate 410 and the magnetic body 310 to prevent the conductive plate 410 from contacting the magnetic body 310. The conductive plate 410 may be disposed apart from the magnetic body 310 by the fixing portion 330. In addition, the fixing portion 330 can be fixed so that the conductive plate 410 can be positioned inside the magnetic field 320.

The magnetic substance 310 and the conductive plate 410 may be applied to the fixing portion 330 by applying an adhesive to the surface of the fixing portion 330. However, the present invention is not limited thereto. The fixing portion 330 may be made of a material other than a conductor.

The conductor 220 passing through the magnetic field generator 210 may include a conductive plate 410, a first conductive line 420, and a second conductive line 430. The first lead wire portion 420 may be covered with the first insulating member 423 to prevent a short circuit and to protect the first lead wire portion 420 from the external environment. The first wire portion 420 may be connected to the power line 120.

The second conductive line 430 may be covered with a second insulation member 433 to prevent a short circuit and protect the second conductive line 430 from the external environment. The second wire portion 430 may be connected to the control portion 230.

A conductive plate 410 may be disposed between the first conductive line portion 420 and the second conductive line portion 430. The conductive plate 410 may be influenced by the magnetic field 320 through the space in which the magnetic field 320 is generated. The conductive plate 410 may be formed to have a larger area than the first and second conductive parts 420 and 430 to maximally receive the influence of the magnetic field 320. Specifically, the first width W1 of the conductive plate 410 is larger than the second width W2 of the first and second lead portions 420 and 430. The area occupying the space in which the magnetic field 420 is formed may be larger than that of the first and second lead portions 420 and 430 because the area of the conductive plate 410 is large. The conductive plate 410 may be disposed apart from the magnetic body 310 in the magnetic field 320 by the fixing portion 330. The present invention is not limited thereto and may be applied to a case where the fixing part 330 and the conductive plate 410 are stacked on the magnetic material 310, As shown in FIG.

When the conductive plate 410 is influenced by the magnetic field 320, the flow rate of free electrons in the conductors of the first and second conductive lines 420 and 430, the power line 120, and the load unit 110 is increased .

The encapsulant 500 may be molded to protect the magnetic body 310, the fixing portion 330, the conductive plate 410, etc. from the external environment, external impact, or the like. The encapsulant 500 may be a nonconductive material, for example, but is not limited to, an epoxy. The encapsulant 500 is shown to have a cylindrical shape, but the present invention is not limited thereto, and the encapsulant 500 may have various shapes.

On the other hand, when the encapsulant 500 is formed, the fixing portion 330 can be unseated. That is, the sealant 500 can mold the place where the fixing portion 330 is disposed. Therefore, the sealing member 500 may perform the function of separating the conductive plate 410 from the magnetic body 310 and fixing the conductive plate 410 in place of the fixing portion 330.

Referring to FIG. 3, the magnetic field generation unit 211 according to another embodiment will be described. The description overlapping with the above description will be omitted, and differences will be mainly described. 3 is a perspective view of a magnetic field generator 211 according to another embodiment of FIG.

Referring to FIG. 3, the magnetic field generating unit 211 according to another embodiment may include a plurality of magnetic bodies 311 and 312. For example, the first magnetic body 311 may be disposed, and the second magnetic body 312 may be disposed apart from the first magnetic body 311. In FIG. 3, the first and second magnetic bodies 311 and 312 are arranged vertically, but the present invention is not limited thereto. In addition, for example, three or more magnetic bodies may be disposed.

The first magnetic body 311 may generate the first magnetic field 321 and the second magnetic body 312 may generate the second magnetic field 322. [ The first magnetic field 321 and the second magnetic field 322 overlap each other to increase the strength of the magnetic field so that the first magnetic field 311 and the second magnetic body 312 are in contact with the first magnetic field 321 and the second magnetic field 322, Are spaced enough to overlap. Between one surface of the first magnetic body 311 facing the first magnetic body 311 and one surface of the second magnetic body 312 facing the first magnetic body 321 and the second magnetic field 322 between the first and second magnetic bodies 311, May have different polarities. 2, the lower surface of the facing first magnetic body 311 is S-pole and the upper surface of the second magnetic body 312 is N-pole.

Since the magnetic field is greatest between the first and second magnetic bodies 311 and 312, the conductor 220 can pass between the first and second magnetic bodies 311 and 312. A first fixing portion 331 is provided between the conductive plate 410 and the first magnetic body 311 to dispose the conductive plate 410 on the first and second magnetic bodies 311 and 312, A second fixing portion 332 may be disposed between the second magnetic bodies 312. The first and second fixing parts 331 and 332 may be made of a material other than a conductor.

The sum of the intensities of the first and second magnetic fields 321 and 322 generated by the first and second magnetic materials 311 and 312 may be 0.1T to 1T.

The encapsulant 500 may be formed to mold the first and second magnetic bodies 311 and 312, the conductive plate 410, and the first and second fixing portions 331 and 332.

Referring to FIG. 4, the magnetic field generator 212 according to another embodiment will be described. The description overlapping with the above description will be omitted, and differences will be mainly described. 4 is a perspective view of a magnetic field generating unit 211 according to another embodiment of FIG.

Referring to FIG. 4, the magnetic field generator 213 may generate the magnetic field 323 using the solenoid 313. Specifically, the solenoid 313 may include a solenoid paddle 313_1 and a solenoid lead 313_2 surrounding the solenoid paddle 313_1. The solenoid paddle 313_1 may be, for example, a ferromagnetic material. The solenoid wire 313_2 may be connected to the control unit 230 to receive power. When electric current is supplied to the solenoid wire 313_2, a magnetic field 323 is generated in the solenoid 313 as shown in FIG. The conductive plate 410 may be disposed so as to pass through the magnetic field 323 and the fixing portion 330 may be disposed between the solenoid 313 and the conductive plate 410 to place the conductive plate 410 in the magnetic field 323 The fixing part 330 may be fixed to be spaced apart from the solenoid 313.

Unlike the magnetic field generator 210 of FIG. 2, when a magnetic body is used as the solenoid 313, power is supplied to the solenoid 313 to generate the magnetic field 323, so that additional power consumption occurs. However, the amount of power saved in the load section 110 is much larger than the amount of power required to generate the magnetic field 323. In addition, the magnetic field 320 of the magnetic body 310 may decrease with time, but when the solenoid 313 is used, the intensity of the magnetic field 323 does not change over time.

The intensity of the magnetic field 323 of the solenoid 313 may be 0.1T to 1T.

Referring to FIG. 5, the magnetic field generator 213 according to another embodiment will be described.

For example, the first solenoid 313 may be disposed and the second solenoid 314 may be disposed apart from the first solenoid 313. In FIG. 5, the first and second solenoids 313 and 314 are arranged vertically, but the present invention is not limited thereto. Further, for example, three or more solenoids may be arranged. The first and second solenoids 313 and 314 include first and second solenoid shims 313_1 and 314_1 and first and second solenoid wires 313_2 and 313_3 which surround the first and second solenoid shims 313_1 and 314_1, , 314_2).

The first solenoid 313 may generate the first magnetic field 323 and the second solenoid 314 may generate the second magnetic field 324. [ The first solenoid 313 and the second solenoid 314 are in contact with the first magnetic field 323 and the second magnetic field 324 because the first magnetic field 323 and the second magnetic field 324 are combined to increase the strength of the magnetic field. They are spaced enough to overlap. Between one surface of the first solenoid 313 facing the first solenoid 313 and the other surface of the second solenoid 314 between the first and second solenoids 313 and 314 in order to join the first magnetic field 323 and the second magnetic field 324, May have different polarities. 5, the lower surface of the facing first solenoid 313 is S-pole and the upper surface of the second solenoid 314 is N-pole.

Since the magnetic field is greatest between the first and second solenoids 313 and 314, the lead wire 220 can pass between the first and second solenoids 313 and 314. A first fixing part 331 is formed between the conductive plate 410 and the first solenoid 313 in order to dispose the conductive plate 410 between the first and second solenoids 313 and 314, The second fixing part 332 may be disposed between the first solenoid 314 and the second solenoid 314.

For example, the solenoid 313 may be disposed, and the magnetic body 310 may be disposed apart from the first solenoid 313. Although the solenoid 313 is illustrated as being disposed on the magnetic body 310 in FIG. 6, the solenoid 313 may be disposed under the magnetic body 310, though not limited thereto.

The solenoid 313 may include a solenoid lead 313_1 and a solenoid lead 313_2 surrounding the solenoid lead 313_1. The solenoid wire 313_2 may be connected to the control unit 230 to receive power.

The solenoid 313 and the magnetic body 310 can generate the magnetic fields 323 and 320, respectively. In order for each of the magnetic fields 323 and 320 to coincide with each other, one side of the first solenoid 313 facing the first side and the first side of the magnetic body 310 may have different polarities. 6, the lower surface of the facing solenoid 313 is an S pole, and the upper surface of the magnetic body 310 is an N pole.

The conductive line 220, particularly the conductive plate 410, can pass between the solenoid 313 and the magnetic body 310. A conductive member 410 is interposed between the conductive plate 410 and the solenoid 313 and between the conductive plate 410 and the solenoid 310 in order to arrange the conductive plate 410 between the solenoid 313 and the magnetic body 310, May be disposed.

The effect of the power efficiency improvement apparatus 200 according to an embodiment of the present invention will be described with reference to FIGS. 8 and 9. FIG. 8 and 9 are views for explaining the effect of the power efficiency improvement apparatus 200 according to an embodiment of the present invention. Specifically, FIG. 8 is a line graph for Table 1, and FIG. 9 is a bar graph showing the effect of the present invention on a weekly basis.

In order to investigate the effect of the power efficiency improvement device 200, the following experiment was conducted. The power efficiency improving apparatus 200 is connected to a power line (three-phase four-wire, 380V) supplied to the entire production line facility (corresponding to the load section 110 in FIG. 1) The line facility produced a daily output. Through this, we calculated how much electricity was used in relation to the output. Because the amount of electricity used per day and the amount of production used in the production line facilities are slightly different from day to day, the power consumption per production amount was obtained in order to accurately grasp the effect. The production unit of the production line is ton (ton) and the unit of power is kwh.

FIG. 8 is a graph showing the contents of [Table 1].

Referring to [Table 1] and FIG. 8, when the power efficiency improvement device 200 is installed in the production line equipment, it can be seen that the power consumption is decreased in relation to the production amount in the production line equipment. The power efficiency improving apparatus 200 improves the flow speed of the free electrons flowing through the power line 120 and the load line 110. This improvement is made sequentially from the power factor improving apparatus 200 side. Therefore, it takes a certain period of time to exhibit the power efficiency improvement effect in the entire production line facility. Therefore, immediately after the power efficiency improvement apparatus 200 is installed, the improvement effect does not appear immediately, and the effect gradually begins to appear over time.

In FIG. 9, averaging is performed on a weekly basis, and the power consumption versus the post-installation production amount is compared with the power consumption before the installation.

The average power consumption per week after installation was 0.0334 kwh / t, which was 0.6% lower than 0.0336 kwh / t before installation. However, the power consumption was 0.0318 kwh / t compared with the average production during the two weeks after installation, and the power consumption was 0.0311 kwh / t compared to the average production during the three weeks after installation. Respectively. Considering that the daily power used by the production line equipment is several thousand kwh, the power efficiency improvement device 200 has excellent power saving effect.

A power efficiency improving apparatus 201 according to another embodiment of the present invention will be described with reference to FIG. The description overlapping with the above-described ones will be omitted and the differences will be mainly described. 10 is a block diagram of a power efficiency improvement device 201 according to another embodiment of the present invention.

The power efficiency improving apparatus 201 of FIG. 10 is connected in series between the power source unit 100 and the load unit 110, unlike the power efficiency improving apparatus 200 of FIG. Specifically, the power efficiency improving apparatus 201 includes a first lead 220a, a second lead 220b, a magnetic field generating unit 210, and a control unit 230. In FIG. 10, the power supply unit 100 exemplarily supplies electric power to three-phase four-wire. The first wire 220a includes four wires 221_1, 223_1, 225_1 and 227_1 and the second wire 220b includes four wires 221_2, 223_2, 225_2 and 227_2 . The number of the first conductor 220a and the second conductor 220b may vary depending on the voltage provided by the power source unit 100. [

The first lead wire 220a is connected to the power source unit 100 and is connected to the control unit 230 through the magnetic field generator 241. [ More specifically, the first sub-conductor 221_1 passes through the first magnetic field generator 241 and is connected to the controller 230. The second sub conductor 223_1 passes through the second magnetic field generator 243 The third sub-conductor 225_1 is connected to the control unit 230 through the third magnetic field generator 245 and the fourth sub-conductor 227_1 is connected to the control unit 230. The fourth sub- (247) and connected to the control unit (230).

The second lead wire 220b connects between the control unit 230 and the load unit 110. Specifically, since the first conductor 220a includes the first through fourth sub-conductors 221_1, 223_1, 225_1, and 227_1, the second conductor 220b includes the fifth through eighth sub-conductors 221_2, 223_2, , 227_2). In other words, the number of the first wires 220a and the number of the second wires 220b are the same. The fifth sub-conductor 221_2 is connected to the first sub-conductor 221_1 through the control unit 230 and the sixth sub-conductor 223_2 is connected to the second sub-conductor 223_1 through the control unit 230 The seventh sub lead 225-2 is connected to the third sub lead 225_1 through the control unit 230 and the eighth sub lead 227_2 is connected to the fourth sub lead 227_1 and the control unit 230 Lt; / RTI >

As shown in FIG. 10, when the power efficiency improving apparatus 201 is connected in series between the power source unit 100 and the load unit 110, the power efficiency improvement effect may be displayed more quickly. When the power efficiency improving apparatus 200 is connected in parallel between the power supply unit 100 and the load unit 110 as shown in FIG. 2, the power efficiency improving apparatus 200 has a remarkable effect after about two weeks as shown in FIG. However, when the power efficiency improving apparatus 201 is connected in series between the power source unit 100 and the load unit 110 as shown in FIG. 10, a remarkable effect can be obtained from two weeks before. Since the resistance of the power efficiency improving apparatus 201 is very small as compared with the resistance of the load unit 110, the operation of the load unit 110 is not affected even when the apparatus is connected in series.

The shape of the magnetic field generating portion 210 of the power efficiency improving apparatus 201 of FIG. 10 and the shape of the first conductor 220a passing through the magnetic field generating portion 210 are the same as those shown in FIGS. 2 to 7 A description thereof will be omitted.

The control unit 230 can control voltage and current flowing through the first and second wires 220a and 220b. For example, the control unit 230 may prevent an overcurrent of the first and second leads 220a and 220b. While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
