摘要
本文在简要分析变压器振动和噪声产生的机理、传播途径和各种影响因素的基础上 ,论述了通过改变变压器油箱的动力特性来控制大型电力变压器振动和噪声的措施。
This paper presents a met hods o f reducing vibration and noise of large power transformers by adjusting dynamic behaviours of the oil tank.It bases on a nalyzing the principle of transformer vi bration and noise generation,propagation path and various kinds of influencing factors.
