Description

Technical Field

[0001] The present invention relates to the technical field of generators, in particular to a mutual induction regenerative generator. Background Art

[0002] Energy issues have always accompanied human progress, significantly reflecting the progress of human civilization. Modern electric energy development has reached considerable advancements. However, both theoretical and practical achievements in physics have focused on converting other forms of energy into electricity, leaving limited research and development of both unknown and known potential within power system operations. In a sense, capacitor reactive power compensation in power systems is a form of potential development and utilization. However, the greatest potential in power systems lies in transformers. This potential can be demonstrated in several ways: 1. The power of a transformer's primary current is equal to the no-load current plus the induced current. This current is induced by and equal to the power of the secondary current. Therefore, no matter how large the secondary current is, it is generated by the primary no-load current, preventing the paradox of the original excitation current being generated by an induced current. 2. According to the second law of magnetic circuits, the magnetomotive force F = lZ. The magnetomotive force is proportional to the primary current l and the number of turns Z in the primary coil. Assuming zero reluctance, the secondary magnetic flux is equal to the magnetomotive force lZ. According to Faraday's law of electromagnetic induction, assuming the secondary circuit resistance is zero and the coil has one turn, then the secondary current is equal to the magnetomotive force, lZ. 3. Faraday's law of electromagnetic induction labels the secondary induced electromotive force as a negative value because the self-inductance back electromotive force of the secondary coil exists. The secondary current always stimulates an increase in the primary current, so the high potential magnetomotive force generated by the transformer's primary winding cannot be utilized and is wasted.

[0003] The conclusion of the above analysis is: no matter how large the transformer load is, it is generated by the transformer primary no-load current, and the no-load current is only about 10% of the transformer rated current.

[0004] Therefore, it is of great significance to develop and utilize these regenerative electrical potentials. Eliminating the self-inductance back electromotive force of the transformer secondary coil and synchronizing the secondary coil current with the primary coil current can eliminate the secondary self-inductance back electromotive force and achieve the purpose of developing and utilizing these potentials. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to eliminate the self-inductance back electromotive force of the transformer secondary winding, provide a method for generating a large magnetic flux potential by utilizing the no-load current of the primary winding, replace the mechanical energy of the synchronous generator rotor with an alternating magnetic field, and equivalently generate an alternating magnetic flux.

[0006] In order to solve the above problems, the technical solution of the present invention is as follows: a mutual induction regenerative electric generator, comprising two U-shaped iron cores and a U-shaped back-to-back iron core;

[0007] The two U-shaped iron cores are located on both sides of the U-shaped back-to-back iron core, and iron core slots are provided in the two U-shaped iron cores. A closed magnetic circuit along the silicon steel sheets is formed between the two U-shaped iron cores and the U-shaped back-to-back iron cores. The two U-shaped iron cores are stacked by silicon steel sheets to form rectangular iron cores of the same length. The notches of the iron core slots are connected to the notches of the U-shaped back-to-back iron cores. The two iron core slots are wound with coil windings in series, which serve as the secondary of the power generation device, that is, the output winding; the U-shaped back-to-back iron core slots are formed by stacking U-shaped back-to-back silicon steel sheets, and the coils wound in the iron core slots are the primary of the device, that is, the excitation winding.

[0008] The technical advancement of the present invention is:

[0009] The excitation winding of the present invention retains the self-inductance back electromotive force of the primary coil of the transformer and the function of the no-load current of the primary winding of the transformer to generate a strong magnetomotive force, because the U-shaped transformation of the iron core also has the ability to provide alternating magnetic flux to the output winding, using the alternating magnetic flux to replace the mechanical force of the generator to do work. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The specific embodiments of the present invention are further described below with reference to the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0013] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0014] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0015] Specific embodiment Figure 1As shown, a mutual inductance regenerative electric generator includes two U-shaped iron cores 1 and a U-shaped back-to-back iron core 2; the two U-shaped iron cores 1 are located on both sides of the U-shaped back-to-back iron core 2, and iron core slots 3 are provided in the two U-shaped iron cores 1. A closed magnetic circuit of silicon steel sheets is formed between the two U-shaped iron cores 1 and the U-shaped back-to-back iron cores 2. The two U-shaped iron cores 1 are stacked by silicon steel sheets to form rectangular iron cores of the same length. The notches of the iron core slots 3 are connected to the notches of the primary iron core. The two iron core slots 3 are wound with coil windings in series as the secondary of the power generation device, that is, the output winding. The U-shaped back-to-back iron cores 2 are stacked by U-shaped back-to-back silicon steel sheets, and the coils wound along the iron core slots serve as the primary of the device, that is, the excitation winding.

[0016] The purpose of this modification to the primary of this device is, firstly, to utilize the self-inductance of the primary winding to generate back EMF and reduce the current. According to the formula for magnetomotive force F = lZ, reducing the current l and increasing the number of winding turns Z can generate the same magnetomotive force while reducing the current, thus creating conditions for the utilization of regenerative electricity. Secondly, by converting the iron core into a slot-type design, alternating magnetic flux can be provided to the output secondary according to the principles of motor generator windings, thereby generating an induced EMF or induced current in the secondary. Because the output winding is on both sides of the excitation winding, it is equivalent to the stator winding of a synchronous generator being on both sides of the rotor, without the self-induced back EMF. Therefore, the self-induced back EMF of the secondary winding is eliminated, which is equivalent to using the no-load current of the transformer primary to generate full-load output power.

[0017] Most current macroscopic laws of physics are natural laws derived from macroscopic experimental results and lack a detailed description of the microscopic laws of electron motion. The mutual inductance regenerative generator we're describing is based on the observation that the direction of electron microscopic motion is nearly perpendicular to the macroscopic direction of current. Why does the secondary current magnetic field of a conventional transformer always prevent changes in the main magnetic field and always stimulate an increase in primary winding current? This is because the back EMF generated by the secondary self-inductance causes the secondary current to lag the voltage by 90 degrees. While microscopic analysis is complex, it's sufficient to understand that the described technology, by converting the secondary winding into a synchronous generator stator winding pattern, eliminates the self-inductance back EMF.

[0018] In the specific implementation process, the primary iron core is stacked with U-shaped back-to-back silicon steel sheets to form a cuboid, and the coil is wound in the slot. This not only retains the properties of the wire wrapped around the iron core, the transformer primary generating self-inductance back electromotive force to control the current and increase the number of winding turns to generate a strong magnetic flux potential, but also has the advantages of the generator rotor core gathering the alternating magnetic field and generating electromagnetic induction with the secondary; the secondary winding and secondary iron core simulate the generator stator winding and iron core and are placed on both sides of the primary, which has the conditions to eliminate the self-inductance back electromotive force of the transformer secondary winding.

[0019] When the primary winding is connected to the excitation power supply, the alternating magnetic flux generated by the primary winding replaces the process in which the generator rotor relies on mechanical force to drive the magnetic field to cut through the stator winding to generate magnetic flux. For example, a synchronous generator generating 50 Hz AC power requires mechanical force to drive the rotor to maintain a speed of 3000 rpm. However, the present invention only needs to provide 50 Hz AC power equivalent to the synchronous generator's excitation DC power to generate an equivalent amount of alternating magnetic flux in the secondary winding, generating an equivalent amount of voltage and current.

[0020] The magnetic field of this current can no longer offset the primary self-inductance back electromotive force and increase the primary current, and there is no need to consider the blocking effect on the rotor.

[0021] According to the magnetomotive force F=lZ, l is the current per turn of the primary coil, and Z is the number of primary turns; according to the second law of magnetic circuit, the magnetic flux of the secondary coil is equal to the magnetomotive force divided by the magnetic resistance; and according to the secondary induced electromotive force is proportional to the rate of change of the magnetic flux, the primary winding has the theoretical basis for the primary small alternating current to provide a large alternating magnetic flux to the secondary while maintaining a small current multi-turn coil.

[0022] According to the fact that the stator winding voltage of the synchronous generator is proportional to the number of stator winding turns and the effective wire length, it provides practical evidence and theoretical basis for the gain of the power generation device.

[0023] It is important to point out that this technical solution goes beyond the conventional drawing rules. Figure 1 The input and output terminals are not marked, but this does not affect the natural existence and use of the input and output terminals in actual operation; there is no special marking of the silicon steel sheet superposition, but this does not affect the understanding of professionals based on the magnetic circuit description; the width of the silicon steel sheets of all superimposed iron cores is consistent to maintain the uniformity of the magnetic resistance of the magnetic circuit, but it does not rule out the possibility of width modification. Figure 1 It is just a schematic diagram and does not represent the asymmetry and uneven magnetic resistance of different parts of the core.

[0024] The specific core cross-sectional area and many related design calculations are based on the gradual improvement of current synchronous generator designs. Because the primary current is small and the secondary current is large, the primary core slot should be designed to be relatively shallow. The secondary current core slot can adopt a C-shaped core slot to increase the slot area to accommodate the high-current conductor.

[0025] Specific embodiment 2: Not only does the transformer primary winding magnetomotive force F=lZ have potential for development and utilization, the transformer secondary winding electromotive force E is proportional to the rate of change of magnetic flux and the number of winding turns, providing a theoretical basis for a small iron core to generate high power.

[0026] As the excitation current of the synchronous generator is about 10% of the output current, the alternating magnetic flux of the 50 Hz alternating current replaces the 50 Hz of the mechanical force rotating magnetic field at 3000 revolutions per minute. In addition, the secondary winding of this device is equivalent to the stator winding of the synchronous generator, and there is no self-inductance back electromotive force, which provides an experimental theoretical basis for achieving the purpose.

[0027] Assume that the core of a 1 kW transformer, the excitation current

[0028] The current is 0.5A, the voltage is 220V, the number of winding turns is 1000 turns, the secondary winding is also 1000 turns, and the voltage is also 220V. Assuming that the leakage magnetic reluctance and secondary resistance are zero, then the secondary current power is 0.5A multiplied by 1000 and then multiplied by 220, which is equal to 110,000 VA, which is equal to 110 kilovolt-amperes.

[0029] A mathematical paradox occurs here in the physical sense: a denominator of 0 is correct, but a denominator of 1 is wrong. Of course, we cannot achieve zero leakage magnetic reluctance resistance, nor can we eliminate the error in the above data, but there is no problem in achieving high power with a small core.

[0030] The development of this technology will greatly reduce the weight of the device and provide considerable convenience for mobile electricity use.

[0031] Specific embodiment three The present invention provides a single-phase AC generator. If a three-phase generator is needed, three groups of devices can be connected in parallel, and the AC excitation current of the corresponding phase can be input respectively.

[0032] The iron core of stacked silicon steel sheets described in the fourth specific embodiment is suitable for low-frequency mutual induction regenerative power generation. After the high-frequency magnetic core is modified in the same way, it is also suitable for high-frequency mutual induction regenerative power generation.

[0033] Specific embodiment 5 has proposed using four U-shaped iron core slots to form a rectangle outward, and winding coils inside and outside the slots as the primary; for other models, the four U-shaped iron core slots are corresponding inward, and the coils wound inside the slots are the secondary output. However, this is only a transitional principle derivation attempt and can be discontinued.

[0034] Specific embodiment six: Based on the current experience that the secondary current of the transformer can feed back the primary to stabilize the voltage, the output current of the present invention can also be processed to meet the frequency and phase requirements to feed back the primary, and it is also possible to supplement or replace the excitation power supply current. The above describes the present invention and its implementation methods. This description is not restrictive. What is shown in the accompanying drawings is only one of the implementation methods of the present invention, and the actual structure is not limited to this. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention, without creatively designing structural methods and embodiments similar to the technical solution, they should all fall within the scope of protection of the present invention.
