How is transformer noise generated? How to reduce noise?

First of all, let's understand the source of transformer noise. Transformer noise mainly comes from two aspects: one is mechanical vibration, and the other is magnetic field vibration. Mechanical vibration is caused by the mechanical force acting on components such as the core, coil and heat sink inside the transformer during operation. And magnetic field vibration is caused by the interaction of magnetic force lines with magnetic conductive materials such as coils and iron cores when the magnetic field inside the transformer changes. These vibrations and sounds are transmitted to the external environment through components such as the transformer shell and heat sink, forming the noise we hear.

So, how to reduce the noise of the transformer? Here are some effective methods:

    Damping measures: Installing shock absorbers or rubber pads at the bottom of the transformer can effectively reduce the impact of mechanical vibration on other components, thereby reducing noise.
    Optimization design: By optimizing the internal structure of the transformer, the mechanical force distribution and heat dissipation performance can be improved, unnecessary mechanical vibration and thermal stress can be reduced, and noise can be reduced.
    Choosing high-quality materials: Using high-permeability, low-loss magnetic materials can reduce magnetic field vibration and energy loss, thus reducing noise.
    Install sound insulation facilities: Installing sound insulation walls, doors, and other facilities around the transformer can effectively isolate the transmission of noise and reduce the impact on the surrounding environment.
    Regular maintenance: Regularly perform maintenance on the transformer, check the fastening and lubrication of various components, etc., to ensure the normal operation of the equipment and reduce unnecessary mechanical vibration and noise.

In short, reducing the noise of transformers requires many aspects, including shock absorption measures, optimized design, selection of high-quality materials, installation of sound insulation facilities, and regular maintenance. By applying these methods comprehensively, the noise of transformers can be effectively reduced, the stability and reliability of equipment operation can be improved, and a more comfortable and quiet living environment can be created for people.
