How to deal with transformer noise

First of all, we need to understand the source and transmission mode of transformer noise. The main noise source of transformer is caused by vibration, so the main means of noise reduction is vibration reduction. The way of communication is through the ground, building structure, doors and windows. Therefore, we should consider these aspects. The basic idea is to reduce the vibration of the transformer, and to absorb and reduce the noise on the ground, walls, doors and windows of the transformer room.

1. Set shock absorber at the bottom of transformer

In order to reduce the structural noise of transformer caused by vibration, it is necessary to adopt high-efficiency and low-frequency vibration isolation treatment for the unit, that is, to set a damper at the bottom of the transformer. Under this measure, the vibration transmissibility can be controlled below 0.2%. The damper used for noise control of transformer must be selected according to the actual situation of different sites.

2. Add noise proof cover outside transformer

In order to further effectively reduce the noise of the transformer, sometimes it is necessary to take strengthening measures, that is, to carry out sound insulation treatment for the transformer room, mainly from the three aspects of doors and windows, ventilation vents, and the ground, through the use of sound insulation doors and windows, noise elimination equipment, floating floor damping pad and other sound insulation products to achieve sound insulation and noise reduction effect.
