供參考與說明用，並非用來對本發明加以限制者。 6/20 201135764 【實施方式】 本發明提出一種低噪音變壓器之製造方法，其係調整 鐵心製作過程的條件參數，以改善變壓器鐵心本身的特 性，而降低變壓器運轉時的噪音值；同時，配合外部置件 的改良，以降低變壓器鐵心與外部殼體之共振所產生的共 振噪音。換言之，本發明所提出之製造方法係從鐵心本身 的特性與外在組裝的態樣等兩方面著手，以製作低噪音變 壓器裝置。 φ 請配合第一圖至第七B圖，本發明所提出之低噪音變 壓器之製造方法可包括以下步驟： 步驟一：製作非晶質合金鐵心，並進行適當的退火製 程（S101)。在此步驟中，非晶質合金鐵心的兩端各具有 一連接端部，每一該非晶質合金鐵心係彎折環繞並藉由每 一該非晶質合金鐵心兩端之該連接端部彼此連接以形成 一封閉鐵心迴圈，並將上述非晶質合金鐵心進行一退火製 程。本發明係先進行多組實驗，以選取最佳化的製程條 • 件，以得到噪音特性最佳的非晶質合金鐵心。請先參考第 二A圖，其顯示經過不同退火溫度之後的鐵心進行XRD . 之繞射角度圖，由XRD之繞射角度圖分析得知，XRD之 繞射之布拉格繞射主峰（接近2 0 = 45° )，經過退火溫度 為390°C以上之退火製程後，鐵心具有較強的鐵及α鐵的 體心立方體（Body-Centered Cubic, BCC)結晶相情形，而 350°C及320°C之退火製程的鐵心之主峰鐵及〇：鐵結晶相 較為微弱，因此致使經過350°C及320°C之退火製程之鐵 心磁滯損失較小（可配合後述之說明）。因此，由材料結 7/20 201135764 晶性的觀點視之，退火溫度不高於350°C係為較佳的退火 條件。然而，根據後述的實驗，為達成低噪音的要求，退 火溫度則較佳為攝氏350度至380度（詳見後述說明）， 換言之，鐵心的退火溫度對於不同鐵心特性會有相斥的選 擇性，故必須依照產品的要求特性選擇適當的製程條件。 同樣的，第二B圖所顯示退火溫度為350°C，配合不同退 · 火時間之製程後，鐵心所呈現的XRD之繞射角度圖，由 圖分析可知，經過較長時間之退火製程的鐵心之主峰鐵及 鐵結晶相較為微弱，纟如10小時與50小時，但越長時間 · 的退火代表能源與製作成本的大幅增加，此亦為生產端必 須考量的問題。 請參考第一圖，其為經過不同退火條件後之鐵心進行 磁力儀（VSM)的測試曲線，主要用於巨觀磁特性的量測。 一般藉由VSM來量測矯頑磁力（Hc)、飽和磁化強度（亦 稱飽和磁通密度，Ms )、磁滯曲線之方形比（squareness, Br/Bs)等性質，而根據第二圖可整理出表1的各項數據。 一般而言，變壓器鐵心其磁滯損失應愈小愈好，以提高 鲁 能量轉換效能，故可得到較小的矯頑磁力（He )及剩磁 (Mr);再者，為了提高磁能密度，高的飽和磁化強度（Ms) 以及高的導磁率亦是較佳磁特性之一。 表1 飽和磁通密度 Saturation magnetization Bs (emu/g) 剩磁 Remanent magnetizatio n Br (emu/g) 矯頑磁力 Coercivit y He (Oe) 方形比 Br/ Bs, squarenes s 電阻率 Resistively p

Description of the Invention: [Technical Field] The present invention relates to a method and apparatus for manufacturing a low-noise transformer, and more particularly to a method for reducing noise of an iron core by using annealing conditions, and using a fixing portion of the mounting frame and The structure in which the ribs of the outer casing member are fixed to each other, and the device of the transformer which reduces the essential noise and resonance noise of the core. Long [Prior Art] The main purpose of the transformer is to change the voltage, change the impedance, and the circuit. In the power transportation, the transformer acts as a heavy knife. The transformer can convert the electric energy into a high voltage and low current form, and the bran is converted back. Therefore, the electrical energy is greatly reduced during the transportation process (1) = the variable pressure n is mainly composed of a main coil, an insulating material, and a core for providing a magnetic circuit, and the transformer core is used to reduce loss (iron loss). Pin Li = made of thin Shishishan steel sheets; or made of amorphous: genus & gold to make the above-mentioned transformer core. Amorphous iron core is a newly developed transformer core. In order to achieve better electrical characteristics, after the group is twisted into a core, it is necessary to: An annealing operation to stabilize its physical and electromagnetic properties. In recent years, in order to achieve the miniaturization of power supply devices, the development of high frequency has been increasing, and the demand for low and high rates has also increased. However, in the conventional structure (4), the winding core is formed around the core. Place the coil and the core in the second:: body 'When the shoe is running, the running sound will resonate with the shell title Γ 4/20 201135764; in addition, because the transformer structure is to fix the multiple cores to each other' ^ Individual iron'. The assembly structure plus the power of high-frequency electromagnetic vibration: easy to generate vibration or resonance, so the transformer sound often causes trouble. D shell! ·Shenmu® This is how the 'magnetic characteristics of the core itself are changed by the pressure. It is a change-production system. The second case of Maoyue has a lack of use in the above-mentioned steaming page display system, and accumulated personal work. Relevant industry development; The structure of the problem is finally rationalized and effectively improved. [Inventive content] dm is to provide a low-noise transformer, which is different from the fine annealing conditions, to change: : Magnetic 1 Temple, which can solve the noise problem of the transformer first; then: Step, the 3 is completely changed _ body material:: The operating noise of the transformer body can be directly transmitted to the variable star;;;: External 'to avoid Produce resonance beer sound, start too 夂^ device white, nest structure to improve the noise problem of the device, core characteristics and " system two: to the present invention provides a low noise transformer heart, each cough is not two Step: providing a plurality of amorphous alloys of iron-junction "iron" (four) each having a connecting end portion, each gold = ΓΛ surface 'final material surrounding the wire (four) - the amorphous junction U and the money end portions are connected to each other To form - closed iron core back 5/20 201135764 a ring, and the amorphous alloy core is annealed at a temperature of 350 to 380 degrees Celsius for two hours; at least one coil is provided, and the coil is wound around the transformer pin formed by the amorphous alloy core to form a transformer body; and performing an assembly step. The assembly step includes the following sub-steps: assembling a mounting frame to the transformer body, and having a fixing portion on the mounting frame; and housing the transformer body and the mounting frame in a housing The inner wall surface of the outer casing member is provided with a rib corresponding to the fixing portion, and the fixing portion is fixed to the rib to stably erect the transformer body in the outer casing member. The invention further provides a low noise transformer. The device comprises: a transformer body comprising an amorphous alloy core and at least one coil, and the amorphous alloy core is annealed at a temperature of 350 to 380 degrees Celsius for two hours; a mounting frame is assembled Fixed to the transformer body, the mounting frame has a fixing portion; and a housing member, the transformer body and the mounting frame The inner wall surface of the outer casing member is provided with a rib corresponding to the fixing portion, and the fixing portion is fixed to the rib to stably erect the transformer body in the outer casing member. The invention has the following Advantageous Effects: The present invention can improve the noise by the magnetic properties of the core, and with the fixed strength of the external structure, so as to reduce the vibration of the transformer body, so that the primary and secondary noise of the transformer can be solved at the same time, so that a low can be obtained. For a better understanding of the features and technical aspects of the present invention, reference should be made to the detailed description of the invention and the accompanying drawings. 6/20 201135764 [Embodiment] The present invention provides a method for manufacturing a low-noise transformer, which adjusts condition parameters of a core manufacturing process to improve the characteristics of the transformer core itself and reduce the noise value during operation of the transformer; With the improvement of external parts, to reduce the resonance between the transformer core and the outer casing The resonance noise. In other words, the manufacturing method proposed by the present invention starts from the characteristics of the core itself and the aspect of external assembly to fabricate a low noise transformer device. φ Please cooperate with the first to seventh B drawings. The manufacturing method of the low noise transformer proposed by the present invention may include the following steps: Step 1: Prepare an amorphous alloy core and perform an appropriate annealing process (S101). In this step, each end of the amorphous alloy core has a connecting end, and each of the amorphous alloy cores is bent around and connected to each other by the connecting ends of each of the amorphous alloy cores. To form a closed core loop, and to perform an annealing process on the amorphous alloy core. The present invention performs multiple sets of experiments to select an optimized process strip to obtain an amorphous alloy core having the best noise characteristics. Please refer to the second A picture, which shows the diffraction angle of the XRD after the different annealing temperatures. The diffraction angle of XRD shows that the main diffraction peak of the diffraction of XRD is close to 2 0 = 45°), after an annealing process with an annealing temperature of 390 ° C or higher, the core has a strong iron- and iron-based body-centered Cubic (BCC) crystal phase, and 350 ° C and 320 ° The main peak of iron and enthalpy of the core of the annealing process of C: the iron crystal phase is relatively weak, so that the core hysteresis loss of the annealing process at 350 ° C and 320 ° C is small (can be described later). Therefore, from the viewpoint of crystallinity of the material layer 7/20 201135764, an annealing temperature of not higher than 350 ° C is a preferable annealing condition. However, according to the experiment described later, in order to achieve low noise requirements, the annealing temperature is preferably from 350 to 380 degrees Celsius (see description below). In other words, the annealing temperature of the core may have a repulsive selectivity for different core characteristics. Therefore, the appropriate process conditions must be selected according to the required characteristics of the product. Similarly, the annealing temperature shown in Figure B is 350 °C. After the process of different annealing time, the XRD diffraction angle diagram of the iron core is analyzed by the graph. After a long period of annealing process, The main peak of iron and iron crystals of iron core are relatively weak, such as 10 hours and 50 hours, but the longer the annealing represents a significant increase in energy and production costs, which is also a problem that must be considered at the production end. Please refer to the first figure, which is a test curve of a magnetometer (VSM) for iron cores subjected to different annealing conditions, and is mainly used for measurement of giant magnetic properties. Generally, the VSM is used to measure the coercive force (Hc), the saturation magnetization (also called the saturation magnetic flux density, Ms), and the squareness (Br/Bs) of the hysteresis curve, and according to the second figure. Sort out the data in Table 1. In general, the transformer core should have a hysteresis loss as small as possible to improve the Lu energy conversion efficiency, so that a smaller coercive force (He) and remanence (Mr) can be obtained; in addition, in order to increase the magnetic energy density, High saturation magnetization (Ms) and high magnetic permeability are also one of the preferred magnetic characteristics.

Furthermore, thirst flow loss is the heat loss caused by the induced current in the core, and its magnitude is inversely proportional to the iron resistance value. Therefore, in order to reduce the thirst loss, the material with lower resistance should be selected. Therefore, according to the table, the iron core of the 320 C, 350 C annealing process has a lower resistance value, which can be used to reduce the eddy current loss and further reduce the iron loss. For the analysis of the % tone characteristics, the square ratio of the hysteresis curve is (8). The noise response caused by the magnetic material is because the magnetic material is in the magnetic field and the magnetic moment (the magnetic claw (10) is deleted in the phase change. The magnetic conversion in the process will cause the magnetic material to generate vibration noise. Therefore, the larger the square ratio, the smaller the noise. Therefore, the core of the 35〇T, i hour and timely annealing process has a larger square ratio.
