Description

Power saving device, power saving system, and power saving multitap

The present invention provides a power-saving device technology that reduces current loss by removing heat generated by harmonic noise, starting current, three-phase imbalance, phase difference of mechanical equipment, inductive load, and thermal action of current, and a power-saving device using this technology , a power-saving system, and a power-saving multi-tap.

More specifically, the present invention relates to a current loss due to heat generated by harmonic noise generated due to a commercial frequency of 60 Hz (or 50 Hz) used in an AC power source, a current loss due to heat generated by the starting current, Current loss due to heat generated by three-phase imbalance, current loss due to heat generated from machinery in the factory, current loss due to heat generated by phase difference of inductive load, Motion generated due to heat generated when current flows through an electric line The present invention relates to a power-saving device technology capable of solving a current loss problem caused by thermal energy, which is energy, and a power-saving device, a power-saving system, and a power-saving multi-tap using the technology.

There are only two conventional technologies for power saving, a voltage drop method and a power factor improvement method, and various products to which this principle is applied are available. The voltage drop method is a general power saving method of most power saving devices installed in the past, and uses the principle of saving power by artificially lowering the voltage (V) within a natural variation value. Also called winding type or transformer type, it is similar to the principle of transformer. However, in the case of the voltage drop method, after installation, the voltage drops to more than the natural fluctuation value (10%), so the brightness of lighting is lowered, noise from electrical equipment or equipment, noise from electrical equipment or equipment, reduced motor rotational speed, and abrasion occur. In the event of a failure of the power saving device itself, there may be electrical hazards and damage to the power system, such as a power outage accident. Therefore, it is not suitable for the facilities of industrial factories that use large power, and it is not used because the problem of reducing the number of revolutions occurs.

Another method is a power factor improvement method. Here, the power factor refers to the difference between the active power used by the load and the apparent power supplied to the load. As an inductive load, a motor is a typical facility, and since the voltage and current (phase difference) differ by 90 degrees and the reactive power is large, reducing it increases the active power and improves the power factor, thereby reducing power loss. . It is usually solved by using an intrinsic capacitor for power factor improvement.

When the phase difference between voltage and current is 0, it is expressed as a power factor of 1.0. When the power factor is 1.0, the ideal state of reactive power is 0, and the reactive power is reduced by advancing the phase of the current. For example, in an electric consumer with a load capacity of 1,000 kW, if the power factor is 1.0, the capacity of the main transformer becomes 1,000 kW / 1.0 = 1,000 kVA, but when the power factor is 0.8, it becomes 1,000 kW / 0.8 = 1,250 kV A About 25% more power loss than 1.0. Therefore, in order to prevent such loss, a power factor improvement method is used. However, in the case of this method, as the function of the capacitor deteriorates, the slowing power factor and the leading power factor fluctuate every 30 minutes, so power loss increases by more than 15% to 20%, or power consumption increases depending on the number of machine operations. do. Therefore, in order to prevent this, measures such as shutting off the power itself are being taken during the evening hours when no operation is being performed.

In the conventional power-saving device technology, in addition to the method of artificially lowering the voltage or reducing the phase difference of the inductive load as described above, the current loss due to the heat action generated when the current flows, the current loss due to harmonic noise, and the current loss due to the starting current However, it was a situation in which energy-saving technology could not be found for the current loss due to the heat generated by the three-phase imbalance and the heat generated by the mechanical device.

The six causes of current loss described above will be described in detail as follows.

(1) In a motor that is an inductive load, the voltage is 90 degrees faster than the current, so power loss due to the phase difference basically occurs. 100% of the power cannot be utilized due to this phase difference. When a current flows through the coil, the frequency increases and heat is generated, so that the flow of current is disturbed. Therefore, the loss of the waveform is converted into heat, which not only shortens the life of the component, but also consumes more power.

(2) The thermal action of electric current is caused by the collision of free electrons and atoms when electric current flows, and the heat (Q) ∝ E (= VIt) increases in proportion to the increase of voltage, current, and time. Typical examples are irons, electric stoves, and hair dryers.

(3) Harmonics are noises generated from the control of equipment and power supply (especially SMPS), which interfere with the flow of free electrons due to the increase in resistance in the conductor and cause current loss.

(4) In the case of starting current, it is a phenomenon that occurs because the resistance value of the motor in the stop state is different from the resistance value of the motor in operation. The resistance value of the motor is very small in the stop state, so when the motor starts operating, a huge amount of current flows. This is called the starting current. A lot of starting current flows due to the sudden start of compressors, compressors and evaporators of refrigerators and air conditioners using motors that are inductive loads (L). As this occurs, the resistance value of the coil gradually increases and the amount of current flowing decreases. Even when the same voltage is applied, the current flows 6 to 10 times higher than in the stationary state where the resistance value is relatively small, and at this time, the current loss occurs excessively.

(5) In the case of 3-phase unbalance, for example, if R phase is 42A, S phase is 15A, and T phase is 2A unbalanced, the voltage drop will be severe where a lot of current flows in the same thickness wire, resulting in power loss. .

(6) Heat generated from mechanical devices (home appliances at home) flows into the electric line and increases the temperature, increasing the resistance component in the line, causing current loss.

The causes of current loss revealed so far are roughly six as described above. The power factor improvement method of compensating for the phase difference of the double inductive load has been developed and used universally. However, current loss due to the heat generated by the phase difference, harmonic distortion, starting current, three-phase unbalance, A solution for preventing current loss caused by heat generated in mechanical equipment and heat energy in the line generated by heat due to the heat action of electric current has not yet been found. Therefore, research is needed to solve this problem.

An object of the present invention to solve the above problems is current loss due to heat generated by harmonic distortion, current loss due to heat generated by starting current, and current loss due to heat generated by three-phase imbalance. , It is to provide a technology that can block current loss due to heat generated in mechanical devices, current loss due to heat generated by the phase difference of inductive load, and current loss due to thermal energy generated due to thermal action that occurs when current flows in an electric line. .

The technology to block current loss is to remove the thermal energy generated due to harmonic noise, starting current, three-phase unbalance, phase difference of equipment, inductive load, thermal action of current, and heat generated by mechanical devices.

Thermal energy refers to kinetic energy existing in lines and systems generated by temperature. Thermal energy originates from random or disordered motion, and in an ideal monoatomic gas, thermal energy refers exclusively to kinetic energy. Heat and thermal energy are distinctly different. Heat is a method of transferring energy, but thermal energy is a type of energy. Therefore, thermal energy has a size (strength, density) according to the total amount of energy.

The present invention provides a technology for stably removing thermal energy existing in electric lines and mechanical devices as described above, and a circuitless power saving device, a power saving system, and a power saving type multi-tap capable of saving power by reducing current loss regardless of impedance using the technique would like to provide

In the method of removing thermal energy according to the present invention, the internal temperature of the electric line (or electric wire) increases to 24° C. to 29° C. when the mechanical device is operated, and if the number of machine operation is constant, this temperature is always maintained. Even if the temperature inside the factory exceeds 60℃, the temperature of the electric line is maintained at the level of 24℃~29℃. The reason is that the electric wire has a plastic (PE: polyethylene) sheath, so the outside temperature does not flow in. 24 ℃ ~ 29 ℃ can be said to be generated by the above six heat generating causes. This temperature varies depending on the amount of current used, but both high-voltage and low-voltage facilities do not exceed this range. The low pressure is 24℃~25℃, and the high pressure (3,300V, 6,600V) is 27℃~29℃. The reason the electric line has only this level of temperature is that the power system does not use transistor components that generate heat over 70℃.

According to the technical idea of the present invention, in order to radiate the thermal energy in the electric line to the outside, a conduction method is used. What can be used here is to use a metal with excellent conduction properties, and to release the internal thermal energy of the electric line to the outside by using the inherent thermal equilibrium characteristic of the metal. Because the temperature inside the line is high, but the temperature of the power-saving device is low, thermal energy is conducted through the metal material inside. Conducted thermal energy is transferred to the power saving device steel plate case and discharged to the outside, so that the temperature in the line can be kept low.

However, all metals with excellent conduction properties have a characteristic of allowing current to pass well, and thus cannot be used because a short circuit problem occurs. Accordingly, the present invention uses a material in which current does not flow while retaining thermal conductivity. The present application uses metal oxides as materials having such properties, and in particular, the applicant has discovered that aluminum oxide, iron oxide, and silicon dioxide can remove thermal energy inside an electric line without a short circuit problem.

In order to remove thermal energy, it must have three representative characteristics. First, it must have excellent insulation properties. Generally, in case of low voltage, the dielectric strength between terminals (R, S, T) should be 10MΩ or more, and high voltage should be 100MΩ or more. Insulation breakdown is also called insulation resistance and is a criterion for determining whether electricity can be conducted between terminals (R, S, T). The device according to the present invention has very excellent insulation properties, with a low voltage of 1,000 MΩ and a high voltage of 14 x 10 ^{4 MΩ.} Second, it must have excellent specific heat characteristics (ability to absorb heat quickly). The metal oxide used according to the present invention does not have worse specific heat properties than any other cooling material. Metal oxide has 5%~7% lower specific heat characteristics compared to normal pure metal, but there is no problem in processing it because the temperature inside the electric line is not high. Third, it must be chemically and thermodynamically stable. Insulation oil in transformer, which is a typical insulator, should be replaced once every 3 to 4 years due to acidification. However, since the metal oxide used in the present invention is already in a state of being combined with oxygen, oxidation progresses when it is continuously in contact with oxygen in the air. Is there a problem that the thermal conductivity properties are lowered? When manufacturing an electric power saving device, it is mixed with an epoxy-based binder (Binder) and molded inside the case, so an epoxy film is formed and further oxidation is not performed. Therefore, the molded metal oxide does not require replacement like insulating oil and does not generate gas, so it can be used semi-permanently for a long time.

According to the present invention, it is possible to minimize current loss due to thermal energy by installing an electric power saving device. In the past, there was no way to remove the thermal energy in the electric line, so current loss due to heat generated by harmonic distortion, current loss due to heat generated by starting current, and heat generated by three-phase imbalance. Current loss, current loss due to heat generated by mechanical devices, current loss due to heat generated by the phase difference of inductive load, and current loss due to thermal action that occurs when current flows through the line. It was possible to cut off the power loss of 10% level. In the case of equipment or factories with low voltage quality or aging, power loss of 12% to 20% can be prevented. In particular, a higher power saving rate can be achieved in factories with more starting current or harmonics.

In addition, since all conventional power saving devices are manufactured using electric circuits, failures or deterioration of functions of components have been provided. However, the electrical power saving devices manufactured according to the present invention are integrated with electrical circuits. As it is not used, there are no problems such as a decrease in the speed (RPM) of the load equipment or a decrease in the illuminance of the lighting. Furthermore, since no electronic components are used in the electric power saving device itself, there is no power consumption element, so power saving is performed stably, and failure does not occur unless artificial damage is applied. Therefore, it can be used semi-permanently for more than 30 years.

In addition, according to the present invention, the power saving device according to the present technology can lower the intensity of harmonic noise due to the removal of thermal energy from the electric line. That is, it is possible to remove harmonic noise in the electric line. Therefore, it is possible to prevent a lot of damage caused by harmonic noise. In addition to current loss, harmonic noise causes a fire by flowing excessive current to the neutral wire, stopping the production line by interfering with the stable operation of the sensor, damaging the PCB and components of the control panel, and accelerating the deterioration of the control panel electronic components. causing damage, etc. If the electric power saving device according to the present invention is installed in the machine, control panel, or the entire factory, the failure rate can be reduced by 80% or more. This means that the situation in which the production line of the automobile parts production plant stops for no reason 3 to 4 times a month is reduced to about once every 6 months if the electric power saving device according to the present invention is installed. In addition, unlike the existing harmonic filter, it is not affected by impedance and can be used in all frequency bands, and high-frequency noise other than harmonics can be removed.

According to the present invention, a power saving device such as a multi-tap outlet power saving device can be used by directly inserting it into a home or office wall outlet without the need to lower the cut-off switch in the distribution box, so there is an advantage that a separate installation process is not required. In addition, a power saving device such as a multi-tap outlet power saving device according to the present invention is a product that adopts a method in which current passes through a load (home appliance, PC, etc.), and functions as a power-saving device by itself even when plugged into a wall outlet. When home appliances such as a PC, air conditioner, or refrigerator are connected to the power saving device slot, this also has a structure that saves power.

The thermal energy removal technology according to the present invention is a necessary technology for the stable operation of various sensors used in autonomous vehicles, electric vehicles, smart cities, and smart factories in the era of the 4th industrial revolution. Distortion & Noise is a typical example of harmonic noise. As described above, since the power saving device of the present invention can remove harmonic noise, stable sensor operation can be implemented.

In addition to improving the power efficiency of electric vehicles, it is possible to improve power quality by improving the power efficiency of autonomous vehicles, smart cities, and smart factories, and to prevent human casualties through stable sensor operation, and to prevent blackouts due to sensor malfunction. There will be. Since it is made of only oxide without an electric circuit, it is strong against impact and does not cause functional deterioration, so it can be used semi-permanently for a long time.

The electric power saving device according to the present invention can be manufactured in various shapes and sizes according to the power consumption capacity, so that it can be manufactured without changing the equipment or circuit of the facility. If necessary, it can be used by inserting it in the middle of the charging cable like a laptop adapter.

Accordingly, embodiments of the present invention should not be construed as limited to the specific shape of the region shown herein, but should include, for example, changes in shape caused by manufacturing.

1 is a table of materials for removing thermal energy according to embodiments according to the spirit of the present invention.

In more detail, this table refers to materials that can be used from an electrical point of view. First, iron (Fe) is a representative material that has magnetism and conducts electricity well. Second, aluminum (Al) and copper (Cu) are materials that do not have magnetism but flow easily. They are mainly used as conductors of electric wires or inner and outer conductors of communication lines. Although the material having the above two characteristics has excellent conductivity, it cannot be used for the purpose of removing thermal energy from the conductor inside the electric wire because a short circuit occurs through the current. The reason is that it is a short circuit.

The third is a material that is magnetic but does not conduct electric current, and a representative example is metal oxide. In other words, these materials have a structure in which oxygen and metal atoms are combined, and these materials do not allow current to flow. The fourth is a material that has no magnetism and does not conduct current, and is often called an insulator. Representative examples include glass, plastic, and rubber. Since these materials do not have conductive properties, they cannot be used to dissipate heat energy in electric lines to the outside.

Accordingly, a material having a third magnetic property but no current flows among the above-mentioned four materials can be used as a conductor necessary for dissipating thermal energy inside the line to the outside in the present invention. Compared to general aluminum or copper, the thermal conductivity is lowered by 7% to 10%, but since the temperature inside the electric line is not as high as 24°C to 29°C, there is no difficulty in using it as a heat energy conductive material. Although the metal used here is already oxidized by contact with oxygen in the air, it is mixed with an epoxy-based binder and molded in the case of the power-saving device to form a film, preventing further oxidation. The conductivity does not deteriorate even after long-term use.

2 is a diagram illustrating a principle of removing thermal energy according to an embodiment of the present invention. More specifically, FIG. 2 is a diagram illustrating the relationship between harmonics, which are representative noises of electric lines, and thermal energy. This cannot be confirmed with an oscilloscope and can be acquired through a spectrum analyzer. The X-axis represents the frequency band, and the Y-axis represents the amplitude (magnitude).

Referring to Figure 2a, the form of harmonics generated by one machine is shown. In this state, the energy density is low, so it has little effect on mechanical equipment or current loss. Harmonics are parasitic waveforms that are multiplied by commercial frequencies (60Hz, 50Hz) used to transmit electricity in AC, and play a role as noise in electrical lines. Generally, harmonics up to the 50th order (3KHz) are called harmonics, and it can affect the quality of electricity up to the 37th order (2.2KHz).

Harmonics are mainly generated during operation in the non-linear characteristics of semiconductor power conversion facilities, transformers and rotating machines, and these facilities include SCR AC phase controller (Heater), UPS (Uninterruptible Power Systems), lighting equipment (DIMMER), and inverter (VVVF). ), DC power system/charger, AC/DC inverter, frequency converter, arc furnace, induction furnace, welding machine, office equipment, home appliance, etc.

Referring to FIG. 2B , it can be seen that the harmonics generated from a plurality of mechanical devices in the factory are overlapped to increase the energy density, and the harmonic level is amplified and sharply increased. There are current harmonics and voltage harmonics in harmonics. In the case of current harmonics, the International Organization (IEC) stipulates that individual harmonics are within 2% to 4%, and THD (Total Harmonic Distortion) standards are within 5%. For voltage harmonics, 5% of individual harmonics and 8% of total harmonic noise (THD) are regulated.

In the case of harmonics, current harmonics are more serious than voltage harmonics. Current harmonics are generated because they are introduced into the power system by the customer's harmonic sources (controllers, motors, inverters, etc.). However, since voltage harmonics are generated by current harmonics and impedance, damage can be reduced by first removing current harmonics.

If the harmonics have higher energy density than specified, it causes serious problems such as breakdown of machinery and production line stoppage, but the biggest damage is that the current loss occurs. It is for this reason that the higher the harmonic generation, the higher the power saving rate.

Referring back to FIG. 2B , the harmonic noise level 200 generated by the single mechanical system in FIG. 2A is relatively low, whereas the harmonics generated by the multiple mechanical system overlap each other and thereby the harmonic level 210 is lowered. It can be seen that increased In this state, the energy density of harmonics is increased, and the kinetic energy is rapidly increased, and the current loss in the line is rapidly increased.

FIG. 2c is an example in which the high level 210 harmonic noise shown in FIG. 2b is removed by installing the electric power saving device according to the embodiments of the present invention. As a result of reducing the kinetic energy of harmonics by removing thermal energy in the line, it can be seen that the level of the amplified harmonics is also greatly reduced.

When the power saving device according to the embodiments according to the technical idea of the present invention is installed for each harmonic generating source in a factory or office, since the harmonic noise force generated in the corresponding zone is primarily reduced, a plurality of harmonics are generated in the power system. Even if multiple overlapping occurs, high-level harmonic noise does not occur. In other words, as shown in FIG. 2c , since the harmonic power of the entire factory is weakened, the resistive component due to the harmonic is reduced, thereby reducing the current loss and solving a lot of damage caused by the harmonic.

Harmonics and power saving are correlated with each other, so removing harmonics naturally results in power saving. When the electric power saving device according to the present invention is installed, it is possible to remove more than 50% of harmonics based on the instantaneous value, thereby increasing the power saving efficiency by 7% to 10%. In addition, more than 80% of failure damage caused by harmonics can be prevented.

3 is a diagram illustrating a process of conducting thermal energy using a power saving device according to embodiments according to the technical idea of the present invention. More specifically, FIG. 3 shows a state in which an electric power saving device is installed on the secondary side of a cut-off switch in a factory so that thermal energy in an electric line is conducted to the power saving device.

Referring to FIG. 3A , when the primary terminal 300 of the cut-off switch in the factory is photographed with a thermal imaging camera, the temperature inside the electric line can be known. The temperature of the electric line connected to the electric load is 24.9 °C and 26.9 °C, respectively. In general, a line electrically connected to an electrical load may have a temperature of 20° C. to 30° C., and the power saving device according to embodiments according to the technical idea of the present invention can realize a power saving effect for a line having such a temperature. let it be

After that, when a power-saving device is installed in the secondary terminal 310 of the cut-off switch and taken with a thermal imaging camera, the temperature inside the electric line can be known. The temperature of the electrical line of the secondary terminal 310 is also 24.9 ℃, 26.9 ℃, respectively. The temperature of the primary side terminal 300 and the temperature of the secondary side terminal 310 are almost the same.

If the surface 320 of the power saving device installed in the secondary terminal 310 is photographed with a thermal imaging camera, the temperature inside the electric line can be known. The photographed surface temperatures were 24.9°C and 26.9°C, respectively. It is almost the same as the primary and secondary side temperatures with only a difference of less than a decimal point. This means that the temperature inside the line is transferred to the power-saving device as it is and heat is conducted.

Although the inside of the line is 24.9°C and 26.9°C, the initial surface temperature of the power-saving device is 12.2°C and 11.2°C, so the thermal energy in the line with a relatively high temperature flows toward the low-temperature power saving device. That is, due to the contact between the line and the insulating heat-conducting material of the power saving device, the insulating heat-conducting material and the line may have the same temperature. With this method and this principle, thermal energy can be released to the outside.

3B is an experimental result comparing the surface temperature of the power saving device before and after the installation of the power saving device measured at two sites. First, at the first site, the surface temperature of the power saving device measured with a thermal imaging camera at room temperature before the power saving device is installed on the electrical load is 12.2°C. After connecting the power saving device to the secondary side of the cut-off switch, the temperature measured by the thermal imaging camera was 24.9℃. That is, when comparing before and after the installation of the power saving device, it can be seen that the surface temperature of the power saving device increased by 12.7°C.

Second, at the second site, the surface temperature of the power saving device measured by a thermal imaging camera at room temperature before the power saving device is installed on the electric load is 11.2°C. After connecting the power saving device to the secondary side of the cut-off switch, the temperature measured by the thermal imaging camera was 26.9℃. That is, when comparing before and after the installation of the power saving device, it can be seen that the surface temperature of the power saving device increased by 15.7°C.

In this way, the thermal energy in the electric line may be conducted to the power saving device according to the embodiments according to the technical idea of the present invention. 90% of the thermal energy introduced into the power saving device is dissipated while being dispersed and absorbed through the oxide inside the power saving device, and about 5% to 10% is emitted to the outside through the steel case of the electrical power saving device. The reason that the heat absorbed inside is dissipated by itself is because the oxide has a volume above a certain level, which depends on the current capacity.

As will be described later, the power saving device may be used at home, and may be implemented as, for example, a multi-tap power saving device. That is, by plugging the multi-tap outlet into the wall outlet, the power saving effect as described above can be achieved.

4 shows a power-saving device to which a thermal energy removal technology according to an embodiment of the present invention is applied.

4A is a diagram illustrating a structure of a parallel type power saving device 400 . The parallel type refers to a structure in which only voltage is applied and no current passes. That is, the load (mechanical device) is not directly connected. The parallel type is mainly used for installation in an existing factory or office building. Since it is not directly connected to the load, it can be installed regardless of the capacity of the machine regardless of low or high pressure. Another reason for using the parallel type is that the distribution box construction is easy.

In general, in the case of a parallel power-saving device according to the present invention, 7% to 8% for a heating furnace, 7% to 8% for an induction type electric furnace, 6% to 7% for a compressor, 8% for an air conditioner, 3% for a general air conditioner %~3.5%, refrigerator 7%~8%, circulation pump 2.5%~3.5%, and bakery oven 20% power saving is possible. When installed in all industrial factories, on average 7%~10%, supermarkets, marts It is possible to save 7% to 8% of energy consumption, 8% to 9% for ice cream stores, 6% to 8% for a flat month, and 9% to 10% for summer.

In order to transmit electricity without loss, the input impedance Zin and the output impedance Zout must be the same. However, the input and output impedances cannot be the same except for superconductors. This is due to the resistive component and reactance component, which causes current loss and ultimately leads to power loss. Reactance refers to the magnitude indicating the magnitude of the disturbance in the flow of current. It is called inductive resistance or responsive resistance, and when current flows through the coil, a magnetic induction action (inductance) occurs, and resistance that prevents the flow of alternating current occurs. This degree of disturbance is called reactance. There are two types of reactance: inductive and capacitive. Inductive reactance (L) is related to the magnetic field generated around a current flowing wire or coil, and capacitive reactance (C) is related to the change in electric field, resulting from two separate conductor plates mediated by an insulating material. . As the frequency increases or decreases, the current value also changes.

A power saving device according to embodiments according to the technical idea of the present invention is a method of removing thermal energy in an electric line generated due to heat, which is a cause of an increase in impedance component caused by external factors, by reducing current loss due to increased impedance. Disclosed is a power saving method for reducing power consumption.

Referring again to FIG. 4 , in FIG. 4A , a parallel power saving device 400 is shown, and in FIG. 4B , a serial power saving device 450 is shown.

Referring to FIG. 4A , a parallel type power saving device having an input line but no output line is illustrated. That is, the conductive wire part 420 is connected to a power system such as an electric load, and the conductive wire part 420 is electrically connected to one end of the electrode part 410 inside the power saving device, but the other part of the electrode part 410 is connected to the other end of the electrode part 410 . The end remains open. The parallel-type power-saving device has a 30% lower power saving rate than the serial-type power-saving device, but it is a necessary structure to facilitate the installation of the power-saving device in a place where electrical facilities are already completed.

With respect to the electrode unit 410 of the parallel-type power saving device, when the power system is single-phase, the two electrode units 410 are implemented, and when the power system is three-phase, the three electrode units 410 can be implemented. . The parallel type power saving device does not need a grounding wire because the power saving principle that is not related to impedance is applied. Similarly, the conducting wire 420 to which the voltage of the power saving device is applied is also composed of two single-phase and three three-phase. Also, in the case of the conducting wire 420 , a grounding wire is not required because the power saving principle that is not related to the impedance is applied.

A thermal energy removal unit 430 is implemented inside the parallel power saving device. The thermal energy removal unit 430 may be configured to remove thermal energy existing in a line such as the electrode part 410 or the conductive wire part 420 . The thermal energy removal unit 430 may include an insulating heat-conducting material disposed to be in contact with the line.

In an embodiment, the thermal energy removal unit 430 may be filled in the parallel-type power saving device and may include an oxide material, particularly an oxide material having dielectric characteristics without applying electricity.

For example, the thermal energy removal unit 430 may include a metal oxide material. The metal oxide material can be obtained from natural minerals or processed products. For example, the metal oxide may be obtained from bauxite or tourmaline. Bauxite or tourmaline may include components necessary to implement a thermal energy removal unit of a power saving device according to embodiments according to the inventive concept.

More specifically, in some embodiments, the conductive oxide material may include aluminum oxide (Al ₂ O ₃ ), iron oxide (Fe ₂ O ₃ ), silicon dioxide (SiO ₂ ), and magnesium oxide (MgO). These substances are also available from bauxite or tourmaline. Bauxite can be used as a mixture of aluminum oxide (Al ₂ O ₃ ), iron oxide (Fe ₂ O ₃ ), silicon dioxide (SiO ₂ ), and other metal salt impurities, and also through tourmaline called tourmaline. It is possible to obtain a metal oxide material having thermal conductivity properties, and may further include one or more materials.

In some embodiments, the insulating heat-conducting material may comprise at least 30% aluminum oxide by weight. A more effective thermal energy removal effect can be achieved with at least 30% by weight of aluminum oxide. For example, for the manufacture of a power saving device, the step of selecting a mineral having a predetermined weight percentage from a plurality of bauxites or a plurality of tourmalines may be performed, and in this case, the mineral having a predetermined weight percentage is at least 30% by weight aluminum oxide.

In a further embodiment, the insulating heat-conducting material may further include iron oxide and silicon dioxide. The insulating heat-conducting material must have insulating properties in addition to thermal conductivity, and iron oxide and silicon dioxide may be materials contributing to such insulating properties. For example, if the material consists only of iron oxide and/or silicon dioxide, insulation may be achieved, but thermal conductivity properties may not be realized.

For example, in order to ensure proper thermal conductivity and insulation, the insulating heat-conducting material is 30-40 wt% aluminum oxide, 10-15 wt% iron oxide, 20-25 wt% silicon dioxide, and 5%-10% magnesium oxide, % by weight. In another example, the insulating conductive material may include 40 to 50% by weight of aluminum oxide, 20 to 30% by weight of silicon dioxide, 5 to 10% by weight of iron oxide, and 5% to 10% by weight of magnesium oxide. In another example, the insulating conductive material may include 50 to 60% by weight of aluminum oxide, 20 to 30% by weight of silicon dioxide, and 5 to 10% by weight of iron oxide. According to these embodiments, the insulating heat conductive material may be manufactured through a simple process without a firing process or an oxidation (drying) process of the pulverized mineral material (ie, insulating heat conductive material).

Meanwhile, bauxite or tourmaline may be used to implement the insulating heat-conducting material having the above-described weight% ratio. For example, bauxite, tourmaline, or a combination thereof satisfying the above-described weight % ratio may be selected from a plurality of bauxite and/or tourmaline by using a component analysis technique such as XRF to AAS. That is, the insulating conductive material may include at least one of a bauxite-based material and a tourmaline-based material. The bauxite or tourmaline may include components necessary to implement the thermal energy removal unit of the power saving device according to embodiments according to the inventive concept.

In some optional embodiments, the insulating heat-conducting material may further include shungite. By adding the pure jite, the compressive strength of the insulating heat-conducting material may be enhanced. In addition, through the fullerene component included in Sunjit, the insulation and thermal conductivity of the insulating heat-conducting material may be enhanced. In addition, Sunjit can perform a noise absorption (filter) function. When pure cheat is added, the weight percent ratio of pure cheat may be less than 10 weight percent.

In another optional embodiment, the insulating heat-conducting material may further include at least one of magnesium oxide and calcium oxide. By adding magnesium oxide and/or calcium oxide, shrinkage of the insulating heat-conducting material that may occur during manufacture of the insulating device can be prevented. That is, magnesium oxide and/or calcium oxide may function as a shrinkage inhibitor of the insulating heat-conducting material.

Magnesium oxide and/or calcium oxide may be included in tourmaline or bauxite. When the components contained in tourmaline or bauxite are small, magnesium oxide and/or calcium oxide may be artificially added. On the other hand, when magnesium oxide and / or calcium oxide is added in excess, the voids may become larger than the critical range due to excessive expansion of the insulating thermal conductivity material, so the added magnesium oxide and / or calcium oxide may be less than 3 wt%.

Referring back to FIG. 4A , the parallel type power saving device according to the present invention has a structure in which current does not flow, and there is no electronic circuit or parts, so no power consumption occurs inside. Therefore, it does not generate noise such as harmonics, and even if the electric power saving device according to the present invention is installed and operated, the power consumption is zero.

4B is a diagram illustrating a structure of a series type power saving device 450 . The series type is the opposite of the parallel type, and the load (mechanical device) is connected to the output line and the current passes through it. It can conduct more thermal energy, so the power saving efficiency is 30% higher than that of a parallel power saving device. Therefore, even in the case of an electric rice cooker, which is a resistive load that is not a power saving target, 5.3% power saving is possible during cooking, and 2.5% power saving is possible in the case of keeping warm. This is an unpredictable number for a parallel power-saving device. When this power saving device is installed as an integral part in the distribution box in the early stage when electrical facilities are not yet built, great power saving efficiency can be expected. It can also be applied to machinery and equipment using large power (up to 6,600V).

Referring to FIG. 4B , the serial type power saving device 450 may include an input line 460 and an output line 470 . This is a structure in which a load (mechanical device) is connected and current flows. For example, an input line 460 may be connected to one end of an electric wire to which a load is connected, and an output line 470 may be connected to the other end of the electric wire. The input line 460 and the output line 470 may be composed of two in the case of a single phase and three in the case of a three phase. In the case of a series type power saving device, there is no need for a separate ground wire because the power saving principle that is not related to impedance is applied.

The conductive wire part 480 through which the voltage and current of the series-type power saving device pass may be connected between the input line 460 and the output line 470 . In one example, the conductive wire unit 480 may be composed of two in the case of a single phase, and three in the case of a three phase. This conductor also has a structure that does not require a grounding wire because the power saving principle that is not related to impedance is applied. In the case of a factory, since the R, S, T lines and the ground wire are placed separately, it may not be possible to accommodate the ground wire separately inside the series type power saving device. That is, it was not accepted because there is no role of the grounding wire in the electric power saving device.

A thermal energy removal unit 490 such as an oxidizing material may be filled in the serial type power saving device. The oxidizing material included in the thermal energy removal unit 490 may be manufactured as a natural mineral (particularly, bauxite and/or tourmaline) or a processed product as described above. The oxide used for the parallel type and the series type may be the same. In some embodiments, even if the oxides used in the parallel type and the series type are the same, their composition ratios may be different from each other.

5 shows a structural diagram of a multi-tap outlet power saving device to which thermal energy removal technology is applied. The multi-tap outlet power saver is a series-type structure through which current passes. The series type is the opposite of the parallel type, and it is a structure in which a load (mechanical device) can be connected to the output line, and current flows through it. Since it can conduct more thermal energy, the power saving efficiency is 30% higher than that of the parallel type. Therefore, in the case of an electric rice cooker, which is a resistive load that is not a power saving target, 5.3% power saving is possible during cooking, and 2.5% power saving is possible in the case of keeping warm. This power saving figure (power saving rate) is relatively high compared to the power saving rate of parallel type power savers.

Referring to FIG. 5 , the power saving device 700 has a single-phase structure including two conductive wires and one ground wire. For example, the power saving device 700 includes a power plug 710 , a first plug insertion hole P1 , a second plug insertion hole P2 , a first conductive wire part 720 , a second conductive wire part 730 , and a grounding part. 740 , and a thermal energy removal unit 750 .

The power plug 710 may be implemented in a 220V structure that can be plugged into a wall outlet, for example. The power plug 710 may include a first terminal T1 and a second terminal T2 . Single-phase AC power may be introduced through the first terminal T1 and the second terminal T2 . AC power introduced through the power plug 710 may be transferred to the plug insertion holes P1 and P2 through the thermal energy removal unit 750 .

The first plug insertion hole P1 may include a third terminal T3 and a fourth terminal T4 . Similarly, the second plug insertion hole P2 may include a fifth terminal T5 and a sixth terminal T6. The first conductive wire unit 720 as a first line may electrically connect the first terminal T1 , the third terminal T3 , and the fifth terminal T5 . The second conductive wire 730 as a second line may electrically connect the second terminal T2 , the fourth terminal T4 , and the sixth terminal T6 . For example, the first conductive wire part 720 and the second conductive wire part 730 are conductive wire parts through which power flows in a single phase, and may be implemented with a copper plate having a purity of 99.8%, and transfer the introduced thermal energy to an oxide, which is a conductor. can play a role.

In some embodiments, the power plug 710 may further include a ground terminal (not shown). In this case, the ground terminal may be connected to the home ground line through the ground unit 740 .

The thermal energy removal unit 750 may be configured to remove thermal energy present in the first conductive wire part 720 and the second conductive wire part 730 . To this end, the thermal energy removal unit 750 may include an insulating heat-conducting material disposed to contact the first conductive wire part 720 and the second conductive wire part 730 . Such an insulating heat-conducting material may be implemented to have the above-described types of materials and their composition ratios.

As the thermal energy inherent in the AC power introduced through the power plug 710 is conducted through the thermal energy removal unit 750, the temperature in the line is lowered and the noise level due to harmonics is also reduced, so that the thermal energy is lowered. This results in lower resistance. At home, an average of 6% to 7% power saving is achieved, and in summer, 8% to 10% power saving is achieved due to the increase in air conditioner use.

6 is a flowchart illustrating a method of manufacturing a power saving device according to embodiments according to the inventive concept.

Referring to FIG. 6 , a mineral having a predetermined weight percentage is selected from a plurality of minerals ( 600 ). For example, from among the plurality of bauxite, bauxite including at least 30% by weight of aluminum oxide may be selected. In another example, from among the plurality of tourmalines, a tourmaline including at least 30% by weight of aluminum oxide may be selected. In an alternative embodiment, a combination of selected minerals (or individual metal oxides) can be made to achieve a specified percentage by weight.

Thereafter, the selected mineral is pulverized (for example, the mineral is pulverized into 100 to 120 mesh), and the pulverized mineral is mixed with a binder to produce a liquid mixture (610). According to embodiments according to the technical spirit of the present invention, the step of generating the liquid mixture may be performed without a separate treatment after the step of pulverizing the mineral. More specifically, the step of generating the liquid mixture may be performed without drying or sintering the pulverized mineral after the step of pulverizing the mineral.

A stirrer may be used to mix the crushed mineral and the binder to form a liquid mixture. For example, a step of mixing the pulverized mineral material and the binder evenly until liquefied using a stirrer may be performed.

Thereafter, the liquid mixture is filled into the case in which the line is disposed ( 620 ). For example, if you want to implement a multi-tap outlet as a power-saving device, pour the liquefied mixture into the multi-tap case. At this time, care should be taken not to form an air layer.

After that, in a state in which the liquid mixture is filled in the case, a drying process is performed at room temperature for about 72 hours (630). Be careful not to crack the surface of the mineral and binder mixture during the drying process.

After drying, a quality check is performed (640). For example, it can be checked whether the surface of the dried mixture has cracks and whether there is a layer of air bubbles. If the quality inspection is not passed, the manufactured device is discarded (650).

If the quality inspection is passed, the manufactured device is used as a finished product. That is, the cover of the power saving device is assembled (660) and an electrical characteristic test (withstanding voltage, insulation resistance, and continuity) is performed.

In order to clearly understand the present invention, it should be understood that the shape of each part in the accompanying drawings is exemplary. It should be noted that it may be deformed into various shapes other than the illustrated shape.

It is common in the art to which the present invention pertains that the present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications and changes are possible within the scope without departing from the technical spirit of the present invention. It will be clear to those who have the knowledge of
