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.
