In recent years

with the rapid development of power system

the demand of reactor product keep increasing. However

the noise pollution of reactor generated during the operation is more and more concerned. Therefore

how to analyze the sources of the noise

formulate the noise estimation method and study the noise reduction measures of the reactor equipment have become the key point to the electrical researchers. As for the noise of bridge arm reactor for flexible DC transmission

the noise spectrum characteristic of the bridge arm reactor is analyzed by the Matlab through site test and selection of sampling point and the the noise test is performed in the factory

finding that the low noise situation is indeed more remarkable. It is therefore necessary to take the noise reduction measures at the bottom of the reactor. Finally

from the perspective of the bridge arm reactor body

the corresponding noise reduction measures

including making the natural frequency of the reactor far away from the electromagnetic force frequency

installing protective cover

using locking nuts

are proposed.
