Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields. Its specific structure is a transformer protection device proposed in patent announcement No. CN220731280U, which includes a mounting plate, a protection box is provided on the top of the mounting plate, and the protection box is fixedly connected to the mounting plate; a bearing plate is provided in the protection box, and the bearing plate is fixedly connected to the protection box; a battery is provided on the top of the bearing plate, and the battery is abutted against the bearing plate; an exhaust fan is provided at the bottom of the bearing plate, and the exhaust fan is fixedly connected to the bearing plate, and the exhaust fan is electrically connected to the battery; a placement plate is provided on the inner bottom wall of the protection box, and the placement plate is slidably connected to the protection box.

[0003] Through the above settings, the transformer of the prior art is equipped with an exhaust fan, a battery, a solar panel and an awning. By starting the exhaust fan, it can not only ventilate the inside of the protective box and prevent excessive humidity, but also reduce the internal temperature. When the weather is hot, the awning effectively avoids direct sunlight on the protective box. At the same time, by arranging a solar panel on the top of the awning, the solar panel generates electricity through sunlight, and the battery collects electricity to provide it to the exhaust fan for use, thereby saving energy.

[0004] However, the transformer of the prior art solution has the following defects during operation:
