摘要

为了降低变压器噪声给人们工作和生活带来的影响

笔者较全面地阐述了变压器噪声控制的重要意义和这些年来国内外的研究成果

说明了振动是产生变压器本体噪声和冷却装置噪声的原因。归纳了变压器噪声的研究方法:变压器远场辐射噪声可以通过实测数据统计和建立计算模型两类方法进行分析

变压器辐射噪声的测量用声强法比传统的声压法更加接近真实情况。详细介绍了变压器的噪声控制方法

在噪声源控制上选用优质高取向硅钢片

在设计、工艺和安装等诸多方面采取有效措施降低噪声;在噪声传播过程中采用缓冲装置、消声法、设置隔音层、隔音室等方法增大噪声在传播过程中的衰减以降低噪声。最后

对变压器噪声控制的发展趋势提出了一些看法。

Abstract

The importance and recent achievements in the field of noise control of power transformer are discussed.Vibration causes the noises of transformer and cooling system.The far-field radiation noise can be analyzed with statistic method of measured data or with calculating model.The sound intensity method is more accurate than the traditional sound pressure method in measuring radiation noise of a transformer.The methods for controlling transformer noise are introduced: for noise source control

using high-quality silicon-steel sheet

and adopting effective measures in transformer design

techniques and installation;for noise propagation control

adopting muffler device

sound insulation board and isolation booth

etc.to enhance noise attenuation.In addition

the trend of the power transformer noise control is prospected.
