Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a winding structure with a magnetic field shielding component. Background Technology

[0002] With the continuous development of power systems, transformers, as key equipment for power transmission and distribution, are crucial for their safe and stable operation. However, transformers generate leakage magnetic fields during operation, which not only interfere with surrounding electrical equipment but also affect the transformer's own performance and lifespan. Furthermore, transformers are susceptible to external electromagnetic waves, reducing their operational stability.

[0003] Currently, although some methods exist to reduce transformer leakage magnetic fields and external electromagnetic interference, these methods often suffer from problems such as complex installation, high cost, and unsatisfactory results. Therefore, there is a need for a shielding protection device that is simple and convenient to install and manufacture, and can effectively reduce the influence of transformer leakage magnetic fields and external electromagnetic waves. Utility Model Content

[0004] The purpose of this invention is to provide a winding structure with a magnetic field shielding component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a winding structure with a magnetic field shielding component, comprising an annular body, the annular body having a notch, the annular body having a connector, the annular body being made of a 2mm thick aluminum plate, used for installation at the lower end of a transformer coil winding, and the annular body being grounded.

[0006] Preferably, the shape of the annular body is designed according to the shape of the transformer winding.

[0007] Preferably, the surface of the annular body is coated with insulating varnish or treated with an anti-oxidation coating.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model effectively reduces the leakage magnetic field of the transformer: by using an annular body made of aluminum plate, it can effectively block and reflect the leakage magnetic field generated inside the transformer, reduce its interference to surrounding electrical equipment, and improve the performance and stability of the transformer; the shielding protection device can block the interference of external electromagnetic waves to the transformer, ensuring the stable operation of the transformer in a complex electromagnetic environment; reducing the influence of leakage magnetic field and external electromagnetic waves reduces the risk of transformer failure and improves its safety and stability; the good shielding effect can reduce the electromagnetic loss and heat generation inside the transformer, and extend its service life; only a 2mm thick aluminum plate is needed to make the annular body, which is installed at the lower end of the transformer winding and reliably grounded. The process is simple, easy to operate, and reduces installation costs and maintenance difficulties. Attached Figure Description
