Research on noise reduction technology of 500kV parallel reactor based on a new composite damping plate

Abstract The requirements for noise control at the boundary of communication substations have been further improved, and it is necessary to meet the Class 2 standard of the Emission Standard for Industrial Enterprise Boundary Environmental Noise (GB12348-2008) . The source control method for the noise of parallel reactors still needs to be further developed. In this context, this paper studies and develops a rubber-based composite damping plate material and completes the noise reduction test of a certain type of parallel reactor with the composite damping plate. The experimental results have verified the effectiveness of this composite damping plate in noise reduction of reactors, with a comprehensive noise reduction of over 8dB (A), providing a new technical solution for noise control of parallel reactors.
