Abstract

In order to effectively suppress the radiated noise of transformers, borrowing the acoustic package design concept from electric vehicle parts, we used the test methods to get aluminum silicate wool porous material Johnson-Allard acoustic parameters (JCA parameters: porosity, flow resistance, tortuosity, visco-thermal characters), and built the transformers with acoustic package model based on the FEA (finite element analysis) method to get the noise reduction performance. For verify the acoustic package simulation model and concept performance on transformer, a 500kV transformer noise reduction test is done. The study results show that the measured results are highly consistent with the simulation results, laying a solid application foundation for the acoustic package design of noise reduction schemes for other power equipment in the future.
