摘　　要：变压器作为电力系统中的关键设备,承担着电能变换的重任,是变电站的主要噪声源之一。针对变压器的铁芯和绕组这两个主要组成部分进行振动的相关机理分析,通过磁场与电动力场的耦合理论分析变压器铁芯和绕组在电磁力作用下产生的应力和形变,探索变压器噪声的产生机理、传播特性及传播规律,并从本体降噪和噪声传播阻隔等方面提出相应的降噪方法。As the key equipment in the power system,the transformer undertakes the important task of electric energy conversion,and is also one of the main noise sources in the substation.In this paper,the vibration mechanism of the core and winding of the transformer is analyzed.The stress and deformation of transformer core and winding under the action of electromagnetic force are analyzed through the coupling theory of magnetic field and electric force field,so as to explore the generation mechanism,propagation characteristics and propagation law of the transformer noise.The corresponding noise reduction methods are proposed from the aspects of body noise reduction and noise propagation barrier.
