摘　　要：由于变压器噪声污染越来越严重,降低变压器噪声迫在眉睫。从理论上阐述了降低油浸式电力变压器噪声的方法,采用一种降低变压器噪声有效的措施—在器身与油箱刚性连接处安装金属橡胶垫,并在变压器振动和噪声试验的基础上验证其效果,为不同类型变压器降噪提供有益参考,并为分析新的降噪方法提供理论依据。The noise pollution of transformer has become increasingly serious, so reducing transformer noise is imminent. This paper theoretically elaborates the oil-immersed power transformer noise reduction methods, adopting an effective measure of reducing transformer noise-installing metal rubber on the rigid joint of the body and the oil tank,and validating its effect on the basis of vibration and noise test of the transformer. It provides benefit reference for noise reduction of different types of transformer and which could help analyze new way to noise reduction.
