Transformer noise control method:
1. Change the door normally used for operation and maintenance personnel to a special fireproof soundproof door. Close the windows that do not need to be open, or change to soundproof windows.
2. Install a ventilation muffler at the exit of the transformer's original fire-fighting exhaust cooling exhaust passage.
3, room walls, ceilings all do sound absorption.
4. Transformer and ancillary equipment are installed on the basis of damper pedestal, and the suspended part is equipped with elastic vibration-damping hanger.
5, single or small transformer equipment or consider the installation of sound enclosures or anechoic chamber governance measures.
Special attention: The noise of transformer equipment has obvious spectrum characteristics. When designing noise control, we must fully consider the different spectral characteristics of the sound source,
