Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to a transformer with a PQ vertical adjustable inductor coil. Background Art
[0002] A transformer is an electrical device used to change AC voltage. It uses the principle of electromagnetic induction to achieve voltage conversion between the input and output ends. The transformer is mainly composed of two or more coils (usually called primary coils and secondary coils) and an iron core.
[0003] However, in situations where power filtering requirements are high and space is limited, conventional transformers do not have adjustable inductors. Most winding structures install a fixed inductor on the PCB board of the power supply to filter out other noises, and the filter occupies a relatively large space. In response to the above problems, the inventors propose a transformer with a PQ vertical adjustable inductor to solve the above problems. Utility Model Content
[0004] In order to solve the problem that when power filtering requirements are high and space is limited, there is no adjustable inductor in a conventional transformer, and it is usually necessary to additionally install a fixed inductor on the PCB board of the power supply to achieve filtering, which will take up a large space; the purpose of the utility model is to provide a transformer with a PQ vertical adjustable inductor.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solution: a transformer with a PQ vertical adjustable inductor coil, comprising a skeleton, wherein there are two skeletons, ferrite cores and pins are installed on the inner sides of the two skeletons, and the pins are located below the ferrite cores. Adjustable inductor coils are installed in the two skeletons, and an adjustable inductor is installed in the adjustable inductor coil.
[0006] Preferably, the adjustable inductance coil added in the middle of the ferrite core is a nickel-zinc material inductor.
[0007] Preferably, the adjustable inductance coil is connected to the adjustable inductor via threads.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] 1. The structure of the utility model saves space and reduces costs: by combining ferrite and nickel-zinc adjustable inductor into one, the functions of inductance adjustment and transformer operating frequency adjustment are realized, avoiding the need for additional components, saving space and reducing costs;
[0010] 2. The utility model improves efficiency and filtering effect: by adding a nickel-zinc inductor in the middle of the ferrite core, the inductance can be adjusted to improve the saturation current capacity and frequency of the transformer. At the same time, the internal nickel-zinc filter is adjusted according to the size of the adjusted inductance to make the magnetic field distribution more concentrated and effectively filter out high-frequency noise, thereby improving the system's efficiency and performance.

[0017] like Figure 1-3 As shown, the utility model provides a transformer with a PQ vertical adjustable inductor, including a skeleton 1, two skeletons 1, a ferrite core 2 and a pin 3 are installed inside the two skeletons 1, the pin 3 is located below the ferrite core 2, an adjustable inductor 4 is installed inside the two skeletons 1, and an adjustable inductor 5 is installed inside the adjustable inductor 4. This new type of PQ vertical adjustable inductor 4 and the transformer adopt a compact vertical design, with a simple and efficient structure. The ferrite core 2 and the adjustable inductor 4 are installed in the two skeletons 1 to achieve precise adjustment of the inductance and improve performance; the pin 3 is reasonably located, easy to connect and maintain, multifunctional, and has a wide range of applications.
[0018] The adjustable inductor coil 4 added in the middle of the ferrite core 2 is a nickel-zinc inductor material.
[0019] By adopting the above technical solution, adding nickel-zinc tunable inductor material to the ferrite core 2 can achieve flexible adjustment of the inductance value, improve its adaptability and performance, work more effectively at different frequencies, optimize circuit performance, and save cost and space.
[0020] The adjustable inductance coil 4 is connected to the adjustable inductance 5 via threads.
[0021] By adopting the above technical solution, the adjustable inductance coil 4 and the adjustable inductor 5 are connected by threads to achieve a simple and reliable connection method, ensuring a stable connection between them, thereby improving the stability and reliability of the entire circuit. This connection method also makes it more convenient to adjust the inductance value, and the height of the adjustable inductor 5 can be adjusted, which can quickly and accurately achieve the required parameter adjustment, and is also convenient for maintenance and replacement.
[0022] Working principle: The ferrite core 2 and the nickel-zinc adjustable inductor are combined into one, which can save space and has the function of adjusting the inductance and changing the operating frequency of the transformer. Since the nickel-zinc material inductor is added in the middle of the ferrite core 2, the inductance can be adjusted and changed to improve the saturation current capacity and frequency of the transformer. The internal nickel-zinc filter is changed according to the size of the adjusted inductance, and the magnetic field distribution will be more concentrated, which can more efficiently filter out high-frequency noise, thereby saving space, reducing costs, and improving utilization efficiency. Through the threaded connection between the adjustable inductance coil 4 and the adjustable inductor 5, the adjustable electric cylinder 5 can be easily installed, and its height can be adjusted, so that the required parameter adjustment can be achieved quickly and accurately, and it is also convenient for maintenance and replacement.
