Description

TECHNICAL FIELD [0001] The present invention relates to an improved multi-stage high voltage generator having a plurality of coil holders,

The present invention relates to a high voltage generator (hereinafter referred to as "multi-stage high voltage generator") having a plurality of coil holders. More specifically, the present invention is a non-magnetic coil fixing body in which three or more winding coils are inserted at regular intervals along the circumferential direction, wherein the winding coils comprise a coil wound without a bobbin, At least two coil fixing bodies, in which the wound coils are arranged so as to be wholly aligned with each other in the axial cross section of the winding coils, and a center hole having a predetermined first diameter is formed in the central portion of the coil fixing body; A common rotating shaft having a predetermined second diameter equal to or smaller than the predetermined first diameter so as to freely rotate within the center hole; And a plurality of N pole and S pole permanent magnets alternately inserted at regular intervals along the circumferential direction and spaced from each other by a predetermined distance on both sides of the coil fixing body, To a multi-stage high voltage generator including at least three magnet rotating bodies through which the common rotating shaft is fixedly inserted.

Conventional air-core generators generate electricity by electromagnetic interaction between a rotating body and a fixed body, and take a method of achieving high efficiency of power generation by removing an iron core.

As a coil used in an actual generator, an iron core type coil in which an iron core is inserted as a core of the coil is used more than an air core type coil simply winding a wire. An iron core refers to a main component having magnetic properties made of an iron-based metal. Such an iron core is used for the purpose of increasing the inductance of the coil. This is related to the coefficient of permeability (specific magnetic permeability) among the characteristics of the core. In the case of an air core type coil, the core is air, so μ = 1. On the other hand, in the case of an iron core, mu is several tens or more, and in some cases, up to 10,000 can be obtained, so that a high inductance can be obtained even with a small number of coils and small coils. For example, the field-type generator disclosed in U.S. Patent No. 5,930,392 uses a coil wound around a toroidal core.

On the other hand, air core type coils have a disadvantage in that the permanent magnet linear type synchronous motor has a magnetic gap much larger than that of the iron core type coils and the thrust density is lowered. On the other hand, detent force force is removed fundamentally, the thrust ripple hardly occurs, and the vertical force is small, so that the control performance is excellent.

However, since a constant circulating magnetic field is not formed in the air core type coil, it is necessary to prevent a voltage drop of the generator. In the low voltage power generation, the charging voltage of the air core type coil is low. A voltage drop occurs. In order to solve this problem, the present invention adopts a method of generating a high charging potential at the coil portion by minimizing the voltage drop by generating a high voltage.

On the other hand, the technique disclosed in Korean Patent Registration No. 10-0683472 is disadvantageous in that the coil is wound around the bobbin to separate the coil fixed by the thickness of the bobbin and the rotating magnet, Thereby eliminating such a technical problem. Another disadvantage of this prior art is that the stationary coil support plate is fixed to the bottom surface of the coil plate and fixed, and there is a possibility that the generator will be severely shaken during the rotation operation of the generator. This is because there is a risk that the magnet will come off.

The technique disclosed in Korean Patent Publication No. 10-2013-002013 relates to a plate-type generator in which magnets are arranged on a magnet rotating plate. Since the coil fixing plate of this plate-type generator is provided with the same number of winding coils as magnets, As shown in the detailed description and the drawings, it is suitable for low-pressure single-phase power generation but has a disadvantage that it is not suitable for high-voltage three-phase power generation. Another disadvantage of this prior art is that when the plate-type generator is operated at a low voltage, a voltage drop may occur depending on the load power when the load is applied to the generated power as in the conventional air-conditioner generator.

The inventor of the present invention intends to provide a detailed technical content of the structure and material according to the present invention which can obtain power energy with high output power by solving the problems of these prior arts and which includes a plan for reducing the size and weight of the generator .

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

1A is a longitudinal cross-sectional view of a multi-stage high voltage generator according to an embodiment of the present invention, FIG. 1B is a rear view of the multi-stage high voltage generator of FIG. 1A as viewed from left to right in FIG. 1A, Is a cross-sectional perspective view of the multi-stage high voltage generator of FIG. 1A.

2A is a longitudinal cross-sectional view of the coil fixing body included in the multi-stage high voltage generator according to the embodiment, FIG. 2B is a front view of the coil fixing body of FIG. 2A, Fig.

1A to 1C and FIGS. 2A to 2C, a multi-stage high voltage generator according to the present invention includes at least two non-magnetic bodies each having at least three winding coils 13 inserted at regular intervals along the circumferential direction Wherein the winding coils (13) comprise a coil wound without bobbins, the winding coils being arranged so as to be wholly aligned with one another in the axial cross section of the winding coils, And a center hole having a predetermined first diameter is formed in the center.

Preferably, the at least two coil fixtures may be spaced apart from each other by a predetermined distance in the axial direction.

Although the term 'high voltage' is used herein to refer to a voltage of usually 0.75 kV to 66 kV, it will be understood by those of ordinary skill in the art that the high voltage does not necessarily have to be limited to the above range.

In one embodiment, the three or more winding coils 13 are three winding coils, and may be inserted into the coil fixing body 120 degrees apart in the circumferential direction.

In one embodiment, the winding coils 13 are configured to have the same height as the coil fixing body, so that the upper end surface of the coil fixing body and the one end face of the winding coils are aligned with each other, The lower end surface and the other end surface of the winding coils can be aligned with each other.

Advantageously, the wound coil included in the wound coil body may be an insulated coil. In the present invention, various insulators may be used to reach a high voltage without causing a short circuit of the coil.

Here, 'insulator' is a term that refers to a nonconductive material that interferes with the movement of electric charge. Even such an insulator can flow a current in an alternating current other than direct current. Since an insulator also has a dielectric constant, if an alternating current is applied, the displacement current or the polarization current flows in proportion to the magnitude of the dielectric constant. The reason why electromagnetic waves can travel into the insulator air is the existence of such a polarization current. In short, an insulator having a very good insulating property refers to a dielectric material having an extremely small dielectric constant.

5 is a cross-sectional view of an exemplary wound coiler according to the present invention.

As one of the methods of forming the insulating coil in the present invention, a quartz glass coating may be applied to the copper wire to prevent the coil from being burned even under a high voltage. This is because the glass- And is an insulating coil 101 which is wrapped around a copper wire and sealed. Here, the polyester mixed material is melted at a high temperature and is coated with a glass coating of at least 0.020 mm to a maximum of 0.135 mm on a copper wire through an extrusion nozzle, so that it is referred to as an optical fiber glass insulation. It is a polyester mixed glass quartz glass coating formed on a copper wire, and it is advantageous that the glass coating is not broken even at 300 degrees Celsius for durability, insulation strength, mechanical strength, flexibility, moisture resistance, chemical resistance and heat resistance.

Since such a glass insulation can be wound to a practical thickness by holding a coil with a thin thickness, the utilization of the glass insulation is very high. Therefore, the leakage potential does not occur until a high voltage of 66 kV and the insulation is not destroyed. ≪ / RTI > As a result, the table showing the relationship between the characteristics of the copper wire forming the insulating coil, the thickness of the glass film, the insulation of the insulating coil, resistance, current, and voltage is shown in Table 1 below.

As shown in Table 1, the insulation coil passed the insulation breakdown test for a small generator coil of 3.3 to 14 kV, and it was tested for a large generator of 25 to 35 kV, 35 to 66 kV, and 66 to 220 kV as well as a medium- It is understood by those skilled in the art that the insulation breakdown test on the coil has also passed and that the insulation coil is suitable for use in the multi-stage high voltage generator according to the present invention.

On the other hand, conventionally used copper varnish films of polyester are formed by coating an insulating varnish having various properties according to the use of copper wire having good electrical conductivity and molding it many times at a high temperature. Such a polyester varnish film Has a heat resistance limit of 220 deg. C, and has a disadvantage that the chemical resistance is excellent in oil resistance and solvent resistance, but is insufficient in film scratch resistance and poor in flexibility. In addition, the withstand voltage is about 10 kV, and the high-voltage insulation treatment of 10 kV or more requires a separate insulation film. If the thickness of the insulation film is increased, the coil volume becomes too large and an efficient winding method can not be achieved. In order to increase the withstand voltage, the volume of the coil is increased, so it is suitable for low voltage and it is used in winding method of transformer.

The glass-film insulation according to the present invention exhibits the characteristics shown in Table 1, so that the cross-sections of the coils are aligned to be hexagonal (a) or square (b) When the winding coils are formed through the winding method, the magnetic force lines are not distorted at the time of high-voltage power generation, and a current higher than the rated load current value can be prevented from flowing to the coils when a load is applied to the coils.

When a coil is wound around a bobbin for winding using a conventional enameled copper wire or the like in a conventional manner without taking such a winding method, a magnetic current line between the coils is distorted at the time of low-voltage power generation so that a current higher than the rated current flows through the coil, However, at high voltage power generation, the coil insulation breaks down and a short circuit occurs due to an interlayer short circuit. Also, in the case of low-voltage power generation, when the coils are wound without being aligned, losses due to resistance are generated as described above due to the induced electromotive force between the coils. In short, it is a good way to increase the efficiency of the generator by adopting a winding system that is fully aligned for both low voltage and high voltage.

Referring again to FIG. 5, the winding coils may further include an insulator formed by an epoxy carburization insulator 102 on the periphery of the wound coil. This is because if a corona is generated between the coil and the magnet rotating body due to a high voltage that can be generated in the insulating coil, the coil may be damaged due to the arc of the coil and the magnet. In order to prevent this, This is because the coil needs to be sealed with a mold.

Insulating materials that can be used for the high voltage generator of the present invention include the following.

First, the glass laminate is laminated with a thin resin sheet and heated under pressure. The resin is mainly made of thermosetting resin (phenol, epoxy, silicone, polyester, etc.) and various reinforcing materials (paper, cotton fabric, glass fiber fabric, non- , It has high heat resistance, excellent mechanical strength and electric insulation and is widely used as an insulating material, a sheathing material, a reinforcing material, and the like. Among them, flame retardant epoxy glass laminate (bakelite) and epoxy plate are typical, and a thin reinforcing sheet of a woven / non-woven form is impregnated with a resin and a thickness chamfering is performed after molding to obtain a desired thickness. The flame-retardant epoxy glass laminate has a volume resistivity of 10-20? Cm and an impact strength of 10 Kgcm / cm or more with an azod or notch. The shielding effect is maintained for a long time, and the mechanical and electrical strength characteristics are excellent. Further, the electrical insulation of the flame-retardant epoxy glass laminate sheet is 100 (KV / mm) or less at low and high pressures, the heat resistance is excellent at 180 degrees Celsius or less, and the abrasion resistance is good.

Next, ceramic is used as a product that is formed by molding non-metallic inorganic compound into raw material and subjected to heat treatment process. Ceramic is a product made by processing or molding a non-metallic or inorganic material at high temperature. There are various types of ceramic, such as a course ceramic using the raw material as it is, and a fine ceramic processed by refining. The characteristics of such ceramics are such that they make sound when they are insulated, stored or electricity, they sense humidity, oxygen content, they are resistant to high heat, they are light and have high strength, and their applications are low voltage, high voltage , Electrical insulators such as ultra-high voltage, magnetic, mechanical, chemical, optical, and biotechnology.

Unlike metals and plastics, such ceramics do not melt or decompose until they reach a very high temperature. In other words, it is excellent in heat resistance or fire resistance and is utilized in various fields as a heat resistant material such as a blast furnace and a stern part of a space ship. This is because, as mentioned above, it has a characteristic that it has a high melting point, is hardly oxidized at a high temperature and is safe at a high temperature. Ceramics and glass are used as insulating materials because ceramics and glass have almost no electricity, and when combined properly, materials with lower conductivity and higher conductivity than insulators can be made.

Such electrical properties of ceramics are utilized in heat exchangers, solar cells, fuel cells, thermoelectric devices, gas turbines, gas materials, optical materials, piezoelectric devices, semiconductors, and dielectric materials. Electrical insulation can maintain insulation up to 746 kV from low voltage to very high voltage. It has high heat resistance and its tensile strength does not change even at 1400 degrees Celsius. The mechanical strength of the ceramic is excellent, but it is fragile. Despite these drawbacks, ceramics are still in widespread use, and their properties have been continually improved.

In the multi-stage high voltage generator of the present invention, the use of the insulator may be different depending on the use, and in particular, the application may be different depending on the voltage. Actually, the present inventor used Beckrite as an insulator in the range of 3.3 kV to 55 kV in the test of the multi-stage high voltage generator of the present invention. It can be understood that a ceramic can also be used as an insulator in the range of 3.3 kV to 345 kV will be.

In one embodiment of the present invention, the non-magnetic material used in the coil fixture may be a processed ceramic having an insulation breakdown voltage of 1500 kV or less.

Referring again to Figs. 2A to 2C, the winding coils 13 according to the present invention can be mounted in the insulating member 12 of the coil fixing body. The winding coils 13, as exemplarily shown in the drawings of the coil fixture shown in Figs. 2B to 2D, can be composed of three, in which case they are generated by the multi-stage high voltage generator according to the invention The winding coils are connected to the three phases of? Or Y. In this case,

Next, referring to FIG. 1A, a multi-stage high voltage generator according to the present invention includes a common rotary shaft (not shown) having a predetermined second diameter equal to or smaller than the predetermined first diameter so as to freely rotate in the center hole 1).

In the multi-stage high voltage generator according to the present invention, the number of the above-mentioned magnet rotating bodies is one more than the number of the above-described coil fixing bodies. This is because the magnet rotating body and the coil fixing bodies are arranged alternately in the axial direction This is because the magnet rotating body is disposed at both ends in the axial direction. For example, in the case of two coil fixtures, there are three magnet rotators. In the case of three coil fixtures, four magnet rotators are provided. In the case of four coil fixtures, the number of magnet rotators is five.

According to one embodiment of the multi-stage high voltage generator of the present invention, when the winding coils are connected in three phases of? Or Y, the number of winding coils which are connected in series corresponding to the number n of the fixed coils is n Dogs.

According to this embodiment, as the number of fixed coils increases by one, the upper limit of the output voltage can be increased by 60 kV. It should be understood, however, that the output voltage according to the number of fixed coils is not necessarily limited to such a range.

The number of the permanent magnets inserted into the magnet rotating body may be four, eight, twelve, sixteen, twenty, etc. In this case, the multi-stage high voltage generator has four poles, 8 poles, 12 poles, 16 poles, 20 poles and so on.

In addition, in one embodiment of the present invention, the number of revolutions of the common rotation shaft 1 is not less than 120 RPM (rotations per minute) and not more than 3,600 RPM, so that the rated frequency of the power generated by the multi- To 120 Hz.

Preferably, the three or more winding coils may have the same dimensions as each other, and the even number of permanent magnets may have the same dimensions. In this case, more preferably, the radius of the permanent magnet may be equal to or larger than the radius of the winding coils. This is to position the winding coils within the magnetic lines of force by the permanent magnets to achieve efficient power generation.

6 is a diagram illustrating a method of superimposing individual magnets in order to configure a permanent magnet to be inserted into a magnet rotating body according to the present invention.

Representative strong magnets used for the individual magnets (indicated by N / S poles) shown in Fig. 6 include neodymium magnets and samarium cobalt magnets. All of them have a strong magnetic force of 3,000 Gauss or more, but it will be understood by a person skilled in the art that the characteristics such as the temperature characteristics and the intensity are different from each other and the characteristics can be compared and a suitable magnet can be selected according to the application.

Among them, neodymium magnets are the most powerful magnets that exert 5,500 gauss of magnetic force. However, they have poor temperature characteristics and their magnetic force can be weakened when they are used at temperatures of 60 to 80 degrees Celsius. However, it is possible to utilize a neodymium magnet having a heat resistance of 220 degrees Celsius, that is, a high-temperature neodymium magnet, through special processing. On the other hand, the samarium cobalt magnet has a magnetic force of 2,000 ~ 3,500 gauss which is 10 ~ 20% weaker than the neodymium magnet, but its temperature characteristic is excellent and it does not lose its magnetic force even at a high temperature of 350 degrees Celsius maximum.

Neodymium magnets through special machining may be used, but in order to obtain a stronger magnetic force, the present inventors have found that by arranging and compressing several neodymium magnets or samarium cobalt magnets in a thin stainless steel case, as schematically shown in Fig. 6 The obtained magnet was used.

4A is a longitudinal sectional view showing a state in which a common rotating shaft, the coil fixing body and the magnet rotating body included in the multi-stage high voltage generator according to the embodiment are assembled, and FIG. 4B is a cross- FIG. 4C is a cross-sectional perspective view of the assembled state of FIG. 4A. FIG.

4A to 4C, the common rotating shaft 1 is fixed to the central portion of the magnet rotating body so as to be freely rotatable in the center hole drilled at the central portion of the coil fixing body, The rotating body is assembled. 4A to 4C also show a rotating insulator 8 for supporting the magnet rotating body fixed to the common rotating shaft 1 and a circular washer 7 for fixing the rotating insulating body 8. [

At this time, the minimum distance between the magnet rotating body and the coil fixing body is preferably 0.7 mm or more and 15 mm or less. As the distance between the winding coils and the permanent magnets increases, the power generation efficiency decreases. By reducing the minimum distance, the generator can be miniaturized and power generation efficiency can be improved. However, kinetic energy loss due to contact due to breakdown or shaking can be prevented It is necessary to appropriately secure the minimum distance to be used. Therefore, the minimum value selected by the inventor through the test operation is 0.7 mm.

It will be appreciated, however, by one of ordinary skill in the art that attempts may be made to lower the minimum distance to less than 0.7 mm, without departing from the gist of the present invention.
