Solution of noise during installation of power transformer

Power transformer installation is not suitable or affected by the installation environment will produce noise, affect the normal use of equipment, resulting in people’s aversion, so solve the power transformer noise is imminent, the following are relevant solutions.

Reason: The installation of the power transformer will exacerbate the vibration of the transformer and amplify the noise of the transformer.

Judging method:

1, the power transformer foundation is not strong or uneven (an Angle hanging), or the bottom plate is too thin.

2, the use of channel steel to frame the power transformer, will increase the noise.

The solution:

1. The original installation method is modified by the installation unit.

2, the power transformer car under the shock-proof rubber pad, can solve some noise.

Installation environment impact:

Cause: The operating environment affects the noise of the power transformer, and the unfavorable environment increases the noise of the transformer by 3dB~7dB.

Judging method:

1, the power transformer room is very large and very empty, no other equipment, there is an echo.

2, the power transformer is too close to the wall, less than 1 meter. The power transformer is placed at the corner, and the wall reflection noise is superimposed with the transformer noise, making the noise increase.

3, the original use of oil change, dry change will affect the transformer noise. The reason is that the crude oil transformer is relatively small, and there is an oil leakage chamber and an oil leakage hole, and the transformer is like placed on a speaker.

The causes of power transformer noise and solutions have been told to everyone, if your power transformer noise generation, may wish to analyze from the above reasons, do a good job of timely treatment, does not affect the normal use of equipment.
