Abstract

Power transformer is the main noise source of substation. In order to reduce the noise of transformer, this paper presents a double layer sound insulation wall structure of transformer tank. The sound insulation performance test of the sample based on the double wall panel structure is completed. Through the measured data and numerical simulation, the results show that the double-layer sound insulation panel has better sound insulation effect. When the air inside the sandwich space is pumped, the sound insulation volume is not significantly improved due to the deformation factor. The feasibility of this method is verified by experiments, which provides technical reference and experimental basis for noise control of oil-immersed transformer.
