High-rise residential basement transformer noise is too large, how to solve, whether the need to shift, there is no other way to solve!
Thank you as much as possible! If you have to do this project also please educated us!
You can consider doing transformer oil, and add noise equipment.
Since it is installed in the basement of high-rise residential, the transformer must be dry-type transformers.
First check the fasteners on the transformer and re-tighten if loosened. Especially the core of the upper and lower clamp, if loose, can not clamp the core noise will be significantly increased.
In addition, if the installation of the foot is stable, etc. also check it.
Note that the transformer must be de-energized when checking and tightening, and then ground properly.
If you really can not reduce the noise of the transformer itself, take sound insulation measures can also have a very significant effect.
For example, in the transformer room wall paste sound-absorbing panels. Or install a cushioning rubber pad underneath the foot of the transformer. If you want to achieve better results you can use a special shock absorber to the top of the transformer, so that it does not directly contact the ground. Can play a very good sound insulation effect (using the above sound insulation measures, basically can make the transformer room next door noise reduction 5 ~ 6dB, or even better)
Transformer noise is mainly caused by magnetostriction of silicon steel sheet.
method:
1, choose a reasonable magnetic density;
2, core clamping;
3, pad to take shock measures;
4, the tank within the parts fastening, does not allow loose metal parts or standard;
5, all the accessories on the tank must be tightened;
6, the use of low noise fan;
7, the installation of the basic level.
Dry-type transformers do not have fuel tanks, remove the other 5, the same, because the dry-type transformers do not have the mailbox, the core magnetic choice, parts fastening, installation foundation leveling is more important
