Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer provided with a shielding member. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It primarily consists of an iron core and coils. Transformers increase or decrease voltage by varying the turns ratio of the coils, thereby meeting the varying needs of power transmission, distribution, and use. Specifically, when AC current passes through the transformer's primary coil, it generates AC magnetic flux in the iron core. This flux induces voltage or current in the secondary coil, thereby achieving voltage change. Transformers are widely designed and applied, including power transformers, test transformers, instrument transformers, and special-purpose transformers. Power transformers are essential equipment for power transmission and distribution, while test transformers are used for performing withstand voltage tests on electrical equipment. The structure and principles of transformers involve not only the fundamental principles of electromagnetics but also a variety of design and manufacturing techniques used in engineering applications to ensure their safe and efficient operation.

[0003] Conventional transformers have a relatively integrated structure. Once the internal structure is damaged, they need to be replaced as a whole, which makes the maintenance cost relatively high. At the same time, the structure lacks a certain degree of shielding protection and is easily affected by external electromagnetic interference, which affects the operational stability.
