[0002] Transformer is the basic equipment for power transmission and distribution, and is widely used in industries, agriculture, transportation, urban communities and other fields. Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, secondary coil and iron core. The main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization and so on.

[0003] When the existing transformer is used, the function of the transformer is to change the AC voltage by using the principle of electromagnetic induction. During the operation of the existing transformer, due to the change of the magnetic field inside the transformer, vibration will be generated. This vibration not only affects the operation safety of the transformer, but also affects the power grid. Usually, a vibration detector or vibration sensor is installed to reduce the vibration, but this method will increase the overall cost and is prone to damage, which increases the maintenance cost.
