Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer with a built-in lightning protection device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. In the power system, transformers are basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields.

[0003] A transformer with lightning protection function disclosed in the Chinese utility model patent application disclosure CN217881062U has a lightning protection mechanism. During the installation of the lightning protection mechanism, the grounding component is screwed into the underground contact ground grid. During daily use, if struck by lightning, the lightning rod will first contact the lightning, and after stable drainage through the lightning ball, impedance support rod and support, it will flow into the ground grid through the lightning wiring and the grounding component, thus achieving the lightning protection effect. It should be noted here that the basic components of the lightning protection mechanism should all be made of conductive metal materials to ensure the normal function of the lightning protection mechanism. The lightning protection mechanism is highly practical and indirectly ensures the service life of the electrical appliance. However, the existing transformer structure is relatively simple and is easily struck by lightning in thunderstorms, thereby causing damage. Utility Model Content
