[0002] Transformer refers to a device that uses the principle of electromagnetic induction to change the AC voltage. Transformers can be divided into power transformers and special transformers according to their uses. Power transformers are mainly used in power transmission and distribution lines to change the AC voltage to meet the needs of different users. Special transformers are used in special fields such as smelting, electrical processing, electric traction, communication, and automatic control. Its main components are primary coils, secondary coils, and iron cores (magnetic cores). The main functions of transformers are: 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 industries such as industry, agriculture, transportation, and urban communities. Medium-frequency transformers are transformers that work within a specific frequency range.

[0016] (3) When the side wall of the transformer body is hit, the present invention first squeezes the side wall of the protective plate and the soft pad. The protective plate and the soft pad can initially mitigate the impact, thereby protecting the side wall of the transformer body and facilitating the operator to better use the device.

[0017] (4) When the protective plate of the present invention moves, it also drives the position of the connecting column to move. The connecting column squeezes the side wall of the moving block, and the moving block squeezes one end of the connecting rod. The connecting rod drives the slider to slide on the side wall of the long rod, and the slider squeezes one end of the compression spring. The compression spring can further reduce the impact and increase the service life of the transformer body. BRIEF DESCRIPTION OF THE DRAWINGS
