Description

Resonant generator

The present invention relates to a generator, in particular to a resonance type generator.

1, a conventional low-speed generator 1 is mainly composed of a stator 11 and a rotor 12 surrounded by the stator 11. The stator 11 has an iron core 111 in the shape of a circular ring, and the iron core 111 faces the rotor 12 One side has a plurality of salient poles 112 arranged at equal intervals and three-phase coils U, V, W wound on the salient poles 112. In addition, the iron core of the stator 11 is usually made of conductive iron or silicon steel sheet. Therefore, when the three-phase coils U, V, and W on the stator 11 are connected to a load and the induced current generated is output to the load, the stator 11 At the same time, eddy currents are also generated on the upper side to generate heat, which causes the resistance of the stator 11 to increase and affects the power generation efficiency.

Moreover, in order to accelerate the excitation, the rotor 12 usually uses a permanent magnet with strong magnetism, such as a neodymium iron boron permanent magnet, but this kind of permanent magnet has conductivity and will induce the eddy current generated on the stator 11 to generate heat, causing the stator 12 to accelerate the demagnetization. And affect the power generation efficiency. And the electric energy (output power) produced by the low-speed generator 1 after operation is fixed and will not change with the change of the connected external load 2. Therefore, as shown in Figure 2, when When the low-speed generator 1 supplies power to the external load 2 through the three-phase coils U, V, and W, but the external load 2 receiving the power fails to consume the electric energy generated by the low-speed generator 1, each of the low-speed generator 1 The phase coils U, V, and W will dissipate the unconsumed electrical energy in the form of heat (heating), which will cause the low-speed generator 1 to heat up and the temperature is higher than a normal value. Therefore, the conventional method must be installed separately The heat dissipation system or cooling system 20 dissipates heat or cools the stator, the rotor and the coils U, V, and W of each phase to cool down the low-speed generator 1. However, the cooling system 20, such as the known water cooling system, gas (hydrogen) cooling system, oil cooling system, water-hydrogen cooling system, or chemical cooling system using liquid nitrogen or liquid hydrogen, is quite bulky, but it is A large amount of energy is also consumed during operation (the power consumption is at least half of the power generated by the low-speed generator 1), so an additional power device 21 (such as another generator set) that provides power to the cooling system 20 is required. ), resulting in lower power generation efficiency.

Therefore, the object of the present invention is to provide a resonant generator that is not easy to raise temperature and generate heat without using an additional cooling system for cooling.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numbers.

3 to 7 are schematic diagrams of the structure of an embodiment of the resonant generator of the present invention, which mainly includes an inner rotor 31, an outer stator 32 and at least one dummy load circuit 33 (see FIG. 7).

The inner rotor 31 includes a circular tubular iron material 311 and 2M (M≧1) permanent magnet units 312 adsorbed on the outer surface of the circular tubular iron material 311 and arranged axially to cover the circular tubular iron material 311, each The permanent magnet unit 312 includes 2N (N≧1) surrounding ferrite permanent magnets 3121 that are adsorbed on the outer surface of the circular tubular iron material 311 and are non-conductive, and the magnetic phases of the ferrite permanent magnets 3121 adjacent to each other Attract each other. For example, as shown in FIG. 3, taking M=1 and N=1 as an example, the inner rotor 31 shown in FIG. 3 has two permanent magnet units 312, and each permanent magnet unit 312 is attracted by two different magnetic fields. It consists of a semi-circular arc-shaped ferrite permanent magnet 3121. The ferrite permanent magnet 3121 is an isotropic permanent magnet sintered from ferrite, and its opposite surfaces are magnetically different. Take Figure 3 as an example. If the outer surface of the ferrite permanent magnet 3121 is N If the ferrite permanent magnet 3121 has an S pole, its inner surface is an S pole. On the contrary, if the ferrite permanent magnet 3121 has an S pole on its outer surface, its inner surface is an N pole.

For another example, as shown in Fig. 4, taking M=1 and N=2 as an example, the inner part shown in Fig. 4 The rotor 31 has two permanent magnet units 312, and each permanent magnet unit 312 is composed of four adjacent arc-shaped ferrite permanent magnets 3121 that are magnetically different and attract each other. For another example, as shown in Figures 5 and 6, it is the case where M>1 and N>2 (Figure 5 takes N=12 as an example), in which each permanent magnet unit 312 is attracted by twelve adjacent magnetic fields. The curved ferrite permanent magnet 3121 is composed. It can be seen that the inner rotor 31 can determine the number of the permanent magnet units 312 to be used and the number of the ferrite permanent magnets 3121 that constitute each permanent magnet unit 312 according to actual application requirements. For example, if used as a high-speed generator, the ferrite permanent magnets 3121 in each permanent magnet unit 312 have a larger area and a small number, and if used as a low-speed generator, each permanent magnet The ferrite permanent magnet 3121 in the unit 312 has a smaller area and a larger number.

As shown in Figures 3 and 4, the outer stator 32 includes at least one sensing unit 321 (Figures 3 and 4 take two sensing units 321 as an example), and the sensing unit 321 has M (M≧1) arranged in a straight line. ) One coil winding 3211, each coil winding 3211 corresponds to two axially adjacent permanent magnet units 312, and each coil winding 3211 includes a magnetically non-conductive nickel-zinc ferrite core 3212 and a winding set in the The coil 3213 on the nickel-zinc ferrite core 3212.

Take Fig. 3 and Fig. 4 as an example, M=1, that is, each induction unit 321 has only one coil winding 3211, and the nickel-zinc ferrite core 3212 is in the shape of "[", and its two ends correspond to the axial direction of the inner rotor 31 Two adjacent ferrite permanent magnets 3121 with opposite magnetic properties. Taking Fig. 5 and Fig. 6 as an example again, the outer stator 32 has three induction units 321, and M>1, That is, each induction unit 321 has a plurality of coil windings 3211, and the nickel-zinc ferrite cores 3212 in the coil windings 3211 are arranged in a straight line along the axial extension direction of the inner rotor 31, and are attached to the inner rotor 31 respectively. The two adjacent permanent magnet units 312 on the circular tubular iron material 311 in the axial direction correspond to each other, that is, one nickel-zinc ferrite core 3212 corresponds to the two axially adjacent permanent magnet units 312. In addition, the coils 3213 of the coil windings 3211 of the induction units 321 are connected in series to form a single-phase coil. Therefore, the three induction units 321 will form three-phase coils R, S, and T. In this embodiment, the outer stator 32 can form three-phase coils R, S, and T as an example. The three-phase coils R, S, and T can be connected into a Y-shaped structure or a delta-shaped structure according to actual application requirements.

Thus, as shown in FIGS. 3 to 6, when the inner rotor 31 rotates relative to the outer stator 32, the permanent magnet units 312 on the inner rotor 31 passing through the sensing units 321 of the outer stator 32 The generated magnetic field will continuously alternately change, so that the coil 3213 in each of the coil windings 3211 of each of the induction units 321 on the outer stator 32 will continuously cut the alternating magnetic field to generate an induced current, which is shown in FIG. 6 The three-phase coils R, S, T will induce current respectively to achieve the purpose of generating electricity.

In addition, as shown in FIG. 7, when the three-phase coils R, S, and T of this embodiment are connected to an external load 5, since the outer stator 32 uses a magnetically conductive and non-conductive nickel-zinc ferrite core 3212, it is not easy to An eddy current is generated on the nickel-zinc ferrite core 3212, and it is not easy to cause the outer stator 32 to generate heat. Therefore, the resistance of the outer stator 32 is not increased, and the power generation efficiency of the generator is not affected or reduced. Furthermore, since the inner rotor 31 uses no The ferrite permanent magnet 3121 is conductive, so the inner rotor 31 is not easy to induce the eddy current generated on the outer stator 32 during the rotation process, so it will not generate heat due to the induced current, so it will not accelerate the demagnetization without affecting The power generation efficiency of the generator. Moreover, since the inner rotor 31 and the outer stator 32 are not easy to generate heat, there is no need to install a heat dissipating system or a cooling system to dissipate heat, so no additional power is consumed, and the power generation efficiency of the generator is not reduced.

And as shown in FIG. 7, this embodiment also has three dummy load circuits 33 correspondingly connected to the three-phase coils R, S, and T. Specifically, the three-phase coils R, S, T are connected in parallel with the three dummy load circuits 33, and each dummy load circuit 33 includes a first non-polar low frequency capacitor C1, a transformer T, A first electrical damper R1, a second non-polar low frequency capacitor C2, and a second electrical damper R2. One end of the first non-polar low-frequency capacitor C1 is electrically connected to one end of the corresponding coil R (S, T). The transformer T is a general 1:1 transformer and has a primary side coil L1 and a secondary side coil L2. One end of the primary side coil L1 is connected to the other end of the first non-polar low frequency capacitor C1.

One end of the first electrical damper R1 is connected to the other end of the primary coil L1, and the other end is connected to the other end of the corresponding coil R (S, T). The second non-polar low frequency capacitor C2 is connected in parallel with the secondary winding L2 of the transformer T. The second electrical damper R2 is connected in parallel with the second non-polar low frequency capacitor C2. And the first and second electrical dampers R1 and R2 are dynamic resistance elements whose resistance values change with frequency, that is, The first and second electrical dampers R1 and R2 are AC resistances with frequency response, such as magnetoresistance, but not limited to this, including dielectric capacitance whose impedance (capacitive reactance) increases with increasing frequency The dielectric inductance (damping capacitor) and impedance (inductive reactance) decrease with the increase of frequency (damping inductance). The detailed working principle can be found in Taiwan Patent No. I423272.

And as shown in Figure 8, the first electrical damper R1 has a reluctance iron core I and a first coil L3 wound on the reluctance iron core, the reluctance iron core I is composed of a silicon steel sheet group I1 and An amorphous iron core I2 is overlapped and combined to form a "mouth"-shaped iron core; one end of the first coil L3 is connected to the other end of the primary coil L1, and the other end of the first coil L3 is connected to the corresponding one The other end of the coil R (S, T) is connected.

Furthermore, as shown in FIG. 9, the magnetoresistive iron core I can also be an inverted "day"-shaped iron core formed by overlapping a silicon steel sheet group I1 and an amorphous iron core I2, and has a vertical and opposite arrangement. The two straight columns, a horizontal column connected to the two straight columns and arranged in parallel, and a middle column arranged between the two straight columns and parallel to the two straight columns, and the first coil L3 is wound On the center pillar. In addition, the detailed structure of the magnetoresistive core I can also refer to the core unit disclosed in Taiwan Patent No. I608694.

The second electrical damper R2 has the same structure as the first electrical damper R1, and also has the magnetoresistive core I as shown in FIG. 8 or 9 and a magnet wound on the magnetoresistive core I The second coil L4, and both ends of the second coil L4 are connected in parallel with the second non-polar low-frequency capacitor C2.

And as shown in Figure 7, both ends of the primary side coil L1 are respectively connected in series with the first non-polar low frequency capacitor C1 and the first electrical damper R1 to form a series resonant circuit, and both ends of the secondary side coil L2 In parallel with the second non-polar low frequency capacitor C2 and the second electrical damper R2, a parallel resonant circuit is formed. And by appropriately selecting the capacitance values of the first non-polar low-frequency capacitor C1 and the second non-polar low-frequency capacitor C2, appropriately selecting the inductance values of the primary side coil L1 and the secondary side coil L2, and appropriately designing the first 2. The second electrical dampers R1 and R2 enable the series resonant circuit and the parallel resonant circuit to have the same resonant frequency, and the resonant frequency is the same as the frequency of the AC power generated by the resonant generator 3, such as 60 Hz .

As a result, as shown in FIG. 7, when the resonance generator 3 is operated, the three-phase coils R, S, T generate induced current and output AC power to the external load connected to the three-phase coils R, S, T. At 5 o'clock, since the electric energy (output power) generated by the resonance generator 3 after operation is fixed, it will not change with the change of the connected external load 5, and the internal resistance of the external load 5 is much smaller than the false The impedance of the resonant load circuit 33, so the electric energy generated by the resonance generator 3 will be preferentially supplied to the external load 5, unless the external load 5 fails to consume the AC power supplied by the resonance generator 3. Each of the coils R, S, and T corresponds to the series resonance circuit in each of the dummy load circuits 33 in parallel to generate series resonance, the impedance of the primary side coil L1 and the first non-polar low frequency capacitor C1 in series is zero, and the first non-polar low frequency capacitor C1 has zero impedance. The resistance of an electrical damper R1 at the resonant frequency is zero, each of the series resonant circuits is equivalent to a short-circuit state, so each of the series resonant circuits will cause the external The remaining AC power (electric energy) that the load 5 fails to consume is completely absorbed, and the absorbed electric energy is coupled to the secondary coil L2 via the primary coil L1 of the transformer T, and temporarily stored in each of the dummy loads In the parallel resonant circuit of the circuit 33, at the same time, since the parallel resonant circuit in each of the dummy load circuits 33 also generates parallel resonance, the secondary side coil L2 and the second non-polar low frequency capacitor C2 form a resonant cavity, The resistance of the second electrical damper R2 at the resonant frequency is zero. Therefore, the electrical energy temporarily stored in the parallel resonant circuit (resonant cavity) will be stored in the secondary coil L2 (electric field energy to magnetic field energy) or The second non-polar low-frequency capacitor C2 (magnetic field energy is converted to electric field energy), and oscillates back and forth between the secondary side coil L2 and the second non-polar low-frequency capacitor C2, and when electric energy is stored in the second non-polar low-frequency capacitor At C2, since the second electrical damper R2 is equivalent to a short circuit at the resonance frequency (resistance is zero), the second non-polar low-frequency capacitor C2 will discharge the second electrical damper R2 to accelerate the energy Dissipation, so that the electric energy entering each of the dummy load circuits 33 is consumed after 5 time constants.

And referring to the hysteresis curve of the silicon steel sheet group I1 and the amorphous iron core I2 shown in Figure 10, it can be seen that compared to the silicon steel sheet, the amorphous iron core has very small hysteresis and eddy current loss, so its iron loss is compared with that of the silicon steel sheet. The iron core is greatly reduced, so that the reluctance iron core I converts electrical energy (from the primary side coil L1) into magnetic energy (the reluctance iron core I is magnetized by the current from the primary side coil L1) and then into electrical energy (secondary side) The coil L2 induces the magnetic flux of the magnetoresistive core I and converts it into electrical energy), which is not easy to heat up. Furthermore, the silicon steel sheet group I1 is wound with a coil and exhibits the characteristics of inductance (that is, the above-mentioned damping inductance), but after the amorphous iron core I2 and the silicon steel sheet group I1 are overlapped and combined to form the reluctance iron core I, it is measured It is found that the amorphous iron core I2 will _{reduce the reactance (X L} ) of the silicon steel sheet group I1. In other words, it will reduce the inductance of the silicon steel sheet group I1. Therefore, it can be inferred that the amorphous iron core I2 has the characteristic of capacitance (ie The above-mentioned damping capacitor), that is, the increase in the susceptance of the capacitor (Y _C , the reciprocal of the reactance X _L ) will reduce the reactance of the inductance, making the magnetoresistive core I less likely to generate a lot of heat and heat up during the magnetoelectric conversion process .

Moreover, because the dummy load formed by the dummy load circuit 33 absorbs electric energy, and converts the electric energy into magnetic energy and then into electric energy, and the electric energy is consumed in the form of oscillation, rather than in the form of heat generation, Therefore, each of the dummy load circuits 33 will not heat up or generate a large amount of heat during the process of consuming electric energy, so there is no need to additionally use a heat dissipation system or a cooling system for heat dissipation.

In summary, the resonant generator 3 of the above embodiment uses a non-conductive ferrite permanent magnet 3121 for the inner rotor 31 and a magnetically conductive, non-conductive nickel-zinc ferrite core 3212 for the outer stator 32, so that the inner rotor 31 The rotor 31 and the outer stator 32 are not easy to generate heat due to the induced current. In addition to not affecting the power generation efficiency due to heat generation, there is no need to additionally use a cooling system for cooling; in addition, by corresponding to the three-phase coils R, S, T The dummy load circuit 33 connected in parallel generates series resonance to absorb the remaining electric energy that is not consumed by the external load 5, and generates parallel resonance through the dummy load circuit 33, so that electric energy is temporarily stored in the parallel resonance circuit and continuously oscillates and passes through the second The electrical damper R2 accelerates the dissipation of electrical energy, so that it does not heat up or generate a large amount of heat during the process of consuming electrical energy, and does not require additional energy. The external use of a cooling system for heat dissipation can indeed achieve the effects and objectives of the present invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
