Analysis and Research on Influence Factors of Power Transformer Noise

本文探讨了电力变电器的噪声产生机理,并对变压器噪声的影响因素进行了分析。通过实验测得实验数据,运用MATLAB仿真软件得出磁通密度与硅钢片磁致伸缩值之间的关系曲线,最后通过对数据的整合分析,得出磁通密度对变压器噪声值的影响变化情况。

As one of the three major public hazards,noise has attracted people′s attention.Electricity is one of the essential energy in people′s daily life and work.In the process of power construction,how to reduce the noise of power transformer to the minimum is one of the most concerned problems of power transformer manufacturing enter prises.Firstly,this paper discusses the noise generation mechanism of power transformer,and analyzes the influen cing factors of transformer noiseThen,use it learn professional knowledge,measure the experimental data,and ob tain the magnetic flux density by the MATLAB simulation software,the relationship curve between the magnetic strictive value of the silicon steel sheet is obtained by the integrated analysis of the data,the influence change of the noise value.
