Description

Technical Field

[0001] This invention belongs to the field of vibration reduction and noise reduction technology for amorphous alloy transformers, specifically referring to a vibration and noise suppression system for amorphous alloy transformers and a vibration reduction optimization method. Background Technology

[0002] The amorphous alloy strip used in amorphous alloy transformers inherently possesses a high magnetostriction coefficient, is brittle and hard, and is easily deformable. This characteristic causes the amorphous alloy core within the transformer to readily generate periodic vibrations during normal operation. These vibrations are gradually transmitted to the transformer tank through the core, windings, clamps, and other internal components, and then radiate outwards, generating noise. This noise not only pollutes the surrounding environment, affecting the daily lives and work of nearby residents, but also exerts a long-term effect on the internal components of the amorphous alloy transformer, leading to loose connections, accelerated wear, severely reducing the transformer's operational stability, shortening its lifespan, and increasing subsequent maintenance costs.

[0003] Currently, existing technologies for suppressing vibration and noise in amorphous alloy transformers are relatively simplistic, mostly targeting only a single link in the vibration transmission chain. For example, they might simply add an elastic damping bushing between the amorphous alloy core and the clamping components to block vibration transmission, or reduce vibration amplitude by adjusting the clamping force of the amorphous alloy core. None of these methods address the root cause of vibration, the path of vibration transmission, or real-time control during equipment operation. This approach results in limited vibration reduction effectiveness and is prone to resonance under varying operating conditions such as load changes and ambient temperature fluctuations, making long-term stable vibration and noise reduction impossible. Furthermore, most existing vibration reduction schemes fail to consider the impact of tension and correction accuracy during amorphous alloy strip winding on subsequent amorphous alloy core vibration, and they do not establish a dynamic correlation between vibration parameters and amorphous alloy transformer operating parameters, resulting in poor practicality and difficulty in meeting real-world application needs.

[0004] Therefore, it is essential to provide a vibration and noise suppression system for amorphous alloy transformers and vibration reduction optimization methods to solve the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technologies and provide a vibration and noise suppression system for amorphous alloy transformers and a vibration reduction optimization method.

[0006] To address the aforementioned technical problems, the present invention provides a vibration and noise suppression system for amorphous alloy transformers. This system employs a three-layer collaborative structure of root source reduction, path blocking, and real-time control, integrated into the amorphous alloy transformer body without affecting its original electrical performance. The system is compact and easy to assemble. It includes a core root source vibration reduction module, a multi-path vibration blocking module, and a real-time monitoring and control module. The core root source vibration reduction module uses an adaptive winding structure with amorphous alloy strip-core parameter coupling, and embeds a customized negative supermagnetic-strictive composite material layer in the core T-region and air gap. The multi-path vibration blocking module features a double-layer composite vibration reduction structure and employs a suspended body assembly process. The real-time monitoring and control module includes a vibration sensor, a temperature sensor, a controller, and a cooling module. These modules work together to achieve comprehensive suppression of vibration and noise in the amorphous alloy transformer.

[0007] Furthermore, the adaptive winding structure of the core root source vibration reduction module can match the width of the amorphous alloy strip and the winding stage parameters in real time during the core winding process, automatically adjust the tension and correction accuracy, and avoid vibration caused by mis-layering and uneven tension of the amorphous alloy strip. The customized negative super magnetostrictive composite material layer can counteract the magnetostrictive effect of the amorphous alloy core, thereby weakening the vibration excitation at the root.

[0008] Furthermore, the dual-layer composite vibration reduction structure of the multi-path vibration blocking module includes an inner elastic damping bushing and an outer adjustable damping device. The inner elastic damping bushing wraps the core and windings, and the outer adjustable damping device is composed of nested springs and damping components. The upper clamp and the side clamp are connected as a whole by reinforcing ribs to improve structural stability.

[0009] Furthermore, the suspended assembly process of the multi-path vibration blocking module enables the core and winding to remain in a non-contact state, avoiding vibration generated by friction during winding, thereby blocking the transmission of vibration from the core and winding to the housing.

[0010] Furthermore, the vibration sensor and temperature sensor are installed at key locations in the core, clamps, and housing to collect vibration acceleration, frequency, and equipment temperature data. The controller can analyze the collected data and can also link with the cooling module to prevent temperature rise from exacerbating the magnetostrictive effect.

[0011] On the one hand, a vibration reduction optimization method for amorphous alloy transformer vibration and noise suppression system is provided. The method follows a synergistic approach of root cause optimization, path optimization, and control optimization, including three steps: core winding and annealing process optimization, vibration reduction structural parameter optimization, and dynamic control strategy optimization. Through the synergistic cooperation of each step, the method achieves precise optimization of vibration and noise of amorphous alloy transformer, and ensures both the vibration reduction effect and practicality and economy. It has an original process design and parameter matching logic.

[0012] Furthermore, the core winding and annealing process optimization adopts a winding method with coordinated control of tension, correction, and speed regulation. Based on the width of the amorphous alloy strip and the preset relevant parameters of the core winding stage, the winding process is adaptively adjusted. At the same time, a multi-dimensional isothermal synchronous heating annealing process is adopted to change the traditional mode of annealing before forming and avoid stress generated during the assembly process.

[0013] Furthermore, the vibration reduction structural parameters are optimized using an electromagnetic-mechanical coupled topology optimization algorithm. With the goal of minimizing vibration and the inductance value as a constraint, the structural parameters of the core air gap region and the vibration reduction device are optimized. The electromagnetic topology optimization result is used as the initial value for the mechanical topology optimization. At the same time, the relevant parameters of the vibration reduction device are optimized to match the vibration frequency of the amorphous alloy transformer under different operating conditions.

[0014] Furthermore, the dynamic control strategy optimizes the correlation model between vibration noise and operating parameters. Based on the real-time data collected by vibration and temperature sensors, the controller dynamically adjusts the parameters of the vibration damping device and the core clamping force to suppress vibration amplification.

[0015] Furthermore, the dynamic control strategy optimization also includes periodically analyzing the data collected by the sensors, adaptively updating the control parameters, ensuring the long-term vibration reduction effect of the amorphous alloy transformer is stable, and automatically activating the reverse harmonic compensation module when DC bias or harmonic interference is detected to cause increased vibration.

[0016] The advantages of this invention compared to the prior art are: 1. The three-layer collaborative structure of this invention forms a complete vibration reduction closed loop. The root-cause weakening module addresses the vibration excitation source, reducing vibration generation; the path blocking module intercepts vibration transmission layer by layer, preventing noise radiation; and the real-time control module dynamically adapts to operating conditions, ensuring stable vibration reduction performance. This collaborative design not only significantly improves vibration reduction and noise reduction efficiency but also adapts to the operating requirements of amorphous alloy transformers under different loads and ambient temperatures. It solves the problems of vibration reduction effect attenuation and easy failure in existing technologies under complex operating conditions, improving the stability and comfort of amorphous alloy transformer operation. 2. The adaptive winding structure of the present invention can match the strip width and winding level parameters in real time, automatically adjust the tension and correction accuracy, avoid defects such as strip mis-lamination and wrinkles, and reduce the vibration hazards generated during the winding process; the customized negative super magnetostrictive composite material layer and the magnetostrictive effect of the iron core cancel each other out, making the total magnetostrictive coefficient approach 0, which weakens the vibration excitation from the root. Compared with the existing single iron core vibration reduction scheme, the vibration reduction effect is significantly improved, and the structural design is reasonable and does not affect the magnetic and electrical performance of the iron core. 3. The multi-path vibration blocking module of the present invention adopts a design that combines a double-layer composite vibration reduction structure with a suspended body assembly process, which can block the transmission of vibration layer by layer, prevent vibration from radiating from the core and windings to the housing, and at the same time effectively improve the structural stability of the equipment, reduce structural vibration, and further improve the vibration reduction and noise reduction effect.

Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0019] Referring to the accompanying drawings, the technical solution provided by this invention is a vibration and noise suppression system for amorphous alloy transformers. The system employs a three-layer collaborative structure of root source reduction, path blocking, and real-time control, integrated into the amorphous alloy transformer body without affecting its original electrical performance.

[0021] In some embodiments, the double-layer composite vibration reduction structure of the multi-path vibration blocking module includes an inner elastic damping bushing and an outer adjustable damping device. The inner elastic damping bushing wraps the core and windings, and the outer adjustable damping device is composed of nested springs and damping elements.

[0022] In some embodiments, the suspended body assembly process of the multi-path vibration blocking module can keep the core and winding in a non-contact state, avoiding vibration generated by friction during winding, thereby blocking the transmission of vibration from the core and winding to the housing.

[0023] In some embodiments, the vibration sensor and temperature sensor are installed at key locations in the core, clamps, and housing to collect vibration acceleration, frequency, and equipment temperature data. The controller can analyze the collected data and can also link with the cooling module to prevent temperature rise from exacerbating the magnetostrictive effect.

[0024] On the one hand, a vibration reduction optimization method for amorphous alloy transformer vibration and noise suppression system is provided. The method follows a synergistic approach of root cause optimization, path optimization, and control optimization, including three steps: core winding and annealing process optimization, vibration reduction structural parameter optimization, and dynamic control strategy optimization. Through the synergistic cooperation of each step, the method achieves precise optimization of vibration and noise of amorphous alloy transformer, and ensures both the vibration reduction effect and practicality and economy. It has an original process design and parameter matching logic.

[0025] In some embodiments, the core winding and annealing process optimization adopts a winding method with coordinated control of tension, correction, and speed regulation. Based on the width of the amorphous alloy strip and the preset relevant parameters of the core winding stage, the winding process is adaptively adjusted. At the same time, a multi-dimensional isothermal synchronous heating annealing process is adopted to change the traditional mode of annealing before forming and avoid stress generated during the assembly process.

[0026] In some embodiments, the vibration reduction structural parameter optimization is performed using an electromagnetic-mechanical coupled topology optimization algorithm. With the goal of minimizing vibration and the inductance value as a constraint, the structural parameters of the core air gap region and the vibration reduction device are optimized. The electromagnetic topology optimization result is used as the initial value for the mechanical topology optimization. At the same time, the relevant parameters of the vibration reduction device are optimized to match the vibration frequency of the amorphous alloy transformer under different operating conditions.

[0027] In some embodiments, the dynamic control strategy optimizes the correlation model between vibration noise and operating parameters. Based on real-time data collected by vibration and temperature sensors, the controller dynamically adjusts the parameters of the vibration damping device and the core clamping force to suppress vibration amplification.

[0028] In some embodiments, the dynamic control strategy optimization further includes periodically analyzing the data collected by the sensors, adaptively updating the control parameters, ensuring the long-term vibration reduction effect of the amorphous alloy transformer is stable, and automatically activating the reverse harmonic compensation module when DC bias or harmonic interference is detected to cause increased vibration.

[0029] The system employs a three-layer collaborative structure of root cause reduction, path blocking, and real-time control, integrated into the amorphous alloy transformer body. During assembly, it strictly avoids impacting the original electrical performance of the amorphous alloy transformer, and its compact overall design facilitates on-site installation and subsequent maintenance. Specifically, the system includes a core root cause vibration reduction module, a multi-path vibration blocking module, and a real-time monitoring and control module. These three modules work collaboratively to achieve comprehensive and multi-dimensional suppression of vibration and noise in the amorphous alloy transformer, addressing the technical pain points of limited vibration reduction effect and poor stability in existing technologies.

[0030] Specifically, the core-source vibration reduction module adopts an adaptive winding structure with amorphous alloy strip-core parameter coupling. Its core function is to weaken the vibration of the amorphous alloy transformer from the source of vibration excitation, thereby reducing noise generation. During the core winding process, to achieve precise matching between the width of the amorphous alloy strip and the winding stage parameters, and to avoid vibrations caused by mis-layering and uneven tension of the amorphous alloy strip, it is necessary to establish a correlation between the winding parameters and the strip parameters. The following mathematical formula enables adaptive tension adjustment: Ft = k⋅δ⋅B, where Ft represents the real-time tension during the winding process (in Newtons); k represents the tension adjustment coefficient, preset according to the material characteristics of the amorphous alloy strip, and is a positive real number used to match the tension requirements of different strip materials; δ represents the thickness of the amorphous alloy strip (in millimeters), and its value directly affects the tension adjustment range; the thicker the strip, the greater the required tension; and B represents the radius of the winding stage (in millimeters), which increases with the number of winding layers. This formula enables dynamic adaptive adjustment of the tension during the winding process, ensuring uniform tension and preventing mis-layering and wrinkling of the amorphous alloy strip, thereby reducing vibration excitation. Simultaneously, a customized negative supermagnetostrictive composite material layer is embedded in the T-shaped region and air gap of the iron core. The magnetostriction coefficient of the customized negative supermagnetostrictive composite material layer is similar in magnitude but opposite in direction to that of the amorphous alloy iron core. The magnetostriction effects of the two cancel each other out, thereby weakening the vibration of the iron core from the source. The magnetostriction effect cancellation relationship can be expressed by the following formula: λtotal=λ1+λ2, where λtotal represents the total magnetostriction coefficient after the iron core and the customized negative supermagnetostrictive composite material layer work together; λ1 represents the magnetostriction coefficient of the amorphous alloy iron core, which is positive and represents the elongation deformation trend of the iron core under the action of a magnetic field; λ2 represents the magnetostriction coefficient of the customized negative supermagnetostrictive composite material layer, which is negative and represents the contraction deformation trend of the composite material layer under the action of a magnetic field. By reasonably designing the composition of the composite material layer, λtotal is made close to 0, thereby effectively canceling the magnetostriction effect and weakening the vibration excitation from the source.

[0031] The multi-path vibration blocking module is used to block the transmission of vibration from the core and windings to the amorphous alloy transformer housing, thereby reducing the outward radiation of noise. This module features a double-layer composite vibration damping structure and employs a suspended housing assembly process. The double-layer composite vibration damping structure includes an inner elastic damping bushing and an outer adjustable damping device. The inner elastic damping bushing tightly wraps around the core and windings, absorbing the vibration energy generated by the core and windings and reducing the transmission of vibration to the clamps. The outer adjustable damping device consists of nested springs and damping elements, and is connected to the upper and side clamps as a whole by reinforcing ribs, improving the structural stability of the amorphous alloy transformer and reducing structural vibration. To optimize vibration reduction, the parameters of the spring and damping components must be appropriately matched. The calculation of the damping force follows the mathematical formula: Fd = c⋅v, where Fd represents the damping force generated by the damping component, in Newtons; c represents the damping coefficient, in Newton-seconds / mm, which is preset according to the rated capacity and vibration frequency of the amorphous alloy transformer and can be dynamically adjusted through the real-time monitoring and control module; v represents the vibration velocity, in millimeters / second, obtained by the vibration sensor. This formula is used to calculate the damping force required by the damping component at different vibration velocities, ensuring that the damping component can effectively absorb vibration energy and block vibration transmission. Simultaneously, the suspended body assembly process adopted by the multi-path vibration blocking module keeps the core and windings in a non-contact state, avoiding vibration generated by friction between them during winding, further blocking the transmission of vibration from the core and windings to the housing, ensuring that vibration is weakened layer by layer during transmission and reducing noise radiation.

[0032] The real-time monitoring and control module is used to collect vibration and temperature data of the amorphous alloy transformer in real time, and dynamically adjust the operating parameters of each module according to the data feedback to avoid resonance and ensure the stability of the vibration reduction effect. The real-time monitoring and control module includes a vibration sensor, a temperature sensor, a controller, and a cooling module. The vibration and temperature sensors are installed at key locations on the core, clamps, and housing. The vibration sensor collects vibration acceleration and frequency data, and the temperature sensor collects equipment temperature data. All collected data is transmitted to the controller for analysis and processing. To determine whether the vibration exceeds the limit, the controller needs to preset a vibration amplitude threshold. The relationship between vibration amplitude and vibration acceleration is expressed by the following mathematical formula: A = ax² + ay² + az², where A represents the vibration amplitude in millimeters per second. 2 ax represents the vibration acceleration in the x-direction, with units of millimeters per second. 2 ay represents the vibration acceleration in the y-direction, with units of millimeters per second. 2 ; az represents the vibration acceleration in the z-direction, with units of millimeters per second. 2This formula is used to synthesize the total vibration amplitude from the three-dimensional vibration acceleration. The controller compares the calculated vibration amplitude with a preset threshold. When the vibration amplitude exceeds the threshold, it automatically adjusts the damping coefficient of the adjustable damping device and the core clamping force of the core root vibration damping module to prevent resonance. Simultaneously, increased temperature exacerbates the magnetostrictive effect of the amorphous alloy core, thereby increasing vibration noise. Therefore, the controller needs to link with the cooling module. The relationship between temperature and the magnetostrictive coefficient can be expressed by the following mathematical formula: λ1=λ0⋅(1+kt⋅ΔT), where λ0 represents the magnetostrictive coefficient of the amorphous alloy core at room temperature; kt represents the temperature coefficient, in °C. -1 The temperature is determined by the amorphous alloy material; ΔT represents the difference between the actual temperature and the room temperature, in °C. When the controller detects that ΔT exceeds the preset range through the temperature sensor, it starts the cooling module to reduce the operating temperature of the amorphous alloy transformer, suppress the aggravation of the magnetostrictive effect, and thus reduce vibration and noise.

[0033] Based on the above-mentioned vibration and noise suppression system for amorphous alloy transformers, this embodiment also provides a vibration reduction optimization method. The method follows a synergistic approach of root cause optimization, path optimization, and control optimization, including three steps: core winding and annealing process optimization, vibration reduction structural parameter optimization, and dynamic control strategy optimization. Each step works together to achieve precise optimization of the vibration and noise of the amorphous alloy transformer, while ensuring the vibration reduction effect and taking into account practicality and economy.

[0034] Among them, optimizing the core winding and annealing process is a key step in reducing vibration excitation at its source. This step adopts a winding method with coordinated control of tension, correction, and speed regulation. Based on the width of the amorphous alloy strip and the preset relevant parameters of the core winding stage, the winding process is adaptively adjusted. The adjustment of the winding speed follows the following mathematical formula: vw=kv⋅Ftδ, where vw represents the winding speed in millimeters per second; kv represents the speed adjustment coefficient, a positive real number preset according to the winding accuracy requirements; Ft represents the real-time tension in Newtons; and δ represents the thickness of the amorphous alloy strip in millimeters. This formula is used to achieve coordinated matching of winding speed, tension, and strip thickness, ensuring a smooth winding process and avoiding strip misalignment and uneven tension caused by excessively fast or slow speeds. Meanwhile, a multi-dimensional isothermal synchronous heating annealing process is adopted, changing the traditional mode of annealing before forming, avoiding stress generated during assembly. The uniformity of annealing temperature is controlled by the following mathematical formula: T(x,y,z)=T0+ΔTmax⋅e−x2+y2+z2r2, where T(x,y,z) represents the annealing temperature at different positions of the core (x,y,z are spatial coordinates in millimeters), in °C; T0 represents the preset annealing reference temperature, in °C; ΔTmax represents the maximum temperature deviation, in °C; and r represents the temperature uniformity adjustment coefficient, in millimeters. This formula ensures that the annealing temperature at all positions of the core is uniform, reducing vibration and noise caused by uneven stress.

[0035] Vibration damping structural parameter optimization is used to optimize the structural parameters of the multi-path vibration blocking module and improve the vibration blocking effect. This step uses an electromagnetic-mechanical coupled topology optimization algorithm to optimize the structural parameters of the core air gap region and the vibration damping device with the goal of minimizing vibration and the inductance value as a constraint. The objective function of the electromagnetic-mechanical coupled topology optimization is: minf(X)=max(A(X)), and the constraint condition is: L(X)≥L0, where f(X) represents the objective function, which is used to characterize the maximum value of the vibration amplitude; X represents the structural parameter vector, including parameters such as the core air gap width, the spring stiffness of the vibration damping device, and the damping coefficient; A(X) represents the vibration amplitude when the structural parameter is X, in millimeters per second. 2L(X) represents the inductance value of the amorphous alloy transformer when the structural parameter is X, in Henry; L0 represents the preset minimum inductance value, in Henry. The combination of this objective function and constraints can minimize the vibration amplitude while ensuring the electrical performance of the amorphous alloy transformer (inductance value meets requirements). Simultaneously, the electromagnetic topology optimization result is used as the initial value for mechanical topology optimization, shortening the optimization convergence time. During optimization, the spring stiffness and damping coefficient of the vibration damping device must match the vibration frequency of the amorphous alloy transformer under different operating conditions to avoid resonance. The resonance judgment formula is: f = f0, where f represents the operating vibration frequency of the amorphous alloy transformer, in Hertz; f0 represents the natural frequency of the vibration damping structure, in Hertz. By optimizing the structural parameters, the difference between f and f0 is kept at a preset value to avoid resonance and further improve the vibration damping effect.

[0036] Dynamic control strategy optimization is used to achieve real-time response and precise control of vibration and noise, ensuring stable long-term vibration reduction effect. This step establishes a correlation model between vibration and noise and operating parameters. The expression of the correlation model is: A=k1⋅I+k2⋅T+k3⋅F, where A represents the vibration amplitude in millimeters per second. 2 I represents the excitation current in amperes; T represents the operating temperature in °C; F represents the core clamping force in Newtons; k1, k2, and k3 are correlation coefficients obtained by fitting experimental data. This model is used to characterize the influence of excitation current, operating temperature, and core clamping force on vibration amplitude. The controller uses the real-time data collected by the vibration sensor and temperature sensor to input into the model, calculates the influencing factors of the current vibration amplitude, and then dynamically adjusts the parameters of the vibration damping device and the core clamping force to suppress vibration amplification. Meanwhile, the data collected by the sensors is analyzed regularly, and the control parameters are updated adaptively to ensure the long-term stable vibration reduction effect of the amorphous alloy transformer. When DC bias or harmonic interference is detected, which causes increased vibration, the reverse harmonic compensation module is automatically activated. The amplitude of the reverse harmonic compensation is calculated by the following mathematical formula: Ic=kc⋅Ih, where Ic represents the amplitude of the reverse harmonic compensation current in amperes; kc represents the compensation coefficient, which is adjusted according to the intensity of harmonic interference; and Ih represents the amplitude of the harmonic current in amperes. By outputting a compensation current that is opposite in direction and matches the amplitude of the harmonic current, the excitation current distortion is reduced and the vibration amplification is suppressed.

[0037] This embodiment achieves synergistic vibration reduction from three dimensions: vibration source, transmission path, and real-time control, through the aforementioned amorphous alloy transformer vibration and noise suppression system and vibration reduction optimization method. All terms correspond completely to the technical solution, the implementation process is clearly explained through detailed textual descriptions, and formal mathematical formulas are supplemented, clearly explaining the meaning and function of the letters and symbols in each formula. This ensures that the implementation process of this invention is repeatable and feasible, effectively solving the technical pain points of existing technologies such as limited vibration reduction effect, easy resonance, and poor stability. It takes into account both practicality and economy and has broad application prospects.

[0038] The advantages of this invention compared to the prior art are: 1. The three-layer collaborative structure of this invention forms a complete vibration reduction closed loop. The root-cause weakening module addresses the vibration excitation source, reducing vibration generation; the path blocking module intercepts vibration transmission layer by layer, preventing noise radiation; and the real-time control module dynamically adapts to operating conditions, ensuring stable vibration reduction performance. This collaborative design not only significantly improves vibration reduction and noise reduction efficiency but also adapts to the operating requirements of amorphous alloy transformers under different loads and ambient temperatures. It solves the problems of vibration reduction effect attenuation and easy failure in existing technologies under complex operating conditions, improving the stability and comfort of amorphous alloy transformer operation. 2. The adaptive winding structure of the present invention can match the strip width and winding level parameters in real time, automatically adjust the tension and correction accuracy, avoid defects such as strip mis-lamination and wrinkles, and reduce the vibration hazards generated during the winding process; the customized negative super magnetostrictive composite material layer and the magnetostrictive effect of the iron core cancel each other out, making the total magnetostrictive coefficient approach 0, which weakens the vibration excitation from the root. Compared with the existing single iron core vibration reduction scheme, the vibration reduction effect is significantly improved, and the structural design is reasonable and does not affect the magnetic and electrical performance of the iron core. 3. The multi-path vibration blocking module of the present invention adopts a design that combines a double-layer composite vibration reduction structure with a suspended body assembly process, which can block the transmission of vibration layer by layer, prevent vibration from radiating from the core and windings to the housing, and at the same time effectively improve the structural stability of the equipment, reduce structural vibration, and further improve the vibration reduction and noise reduction effect.
