电力变压器噪声分析与有源降噪探讨

Noise analysis and active noise reduction of power transformers

近年来,在国民经济发展速度不断加快的背景下,大部分高压大容量变压器安装的位置与市区距离逐渐缩小,直接影响了人们正常工作与生活,同样也诱发了大型变压器噪声控制的系列问题。在现代控制技术发展的背景下,控制芯片成本降低,使得有源降噪技术被广泛应用于变压器噪声控制过程中。基于此,文章将电力变压器作为主要研究对象,阐述了噪声分析和有源降噪的措施,希望有所帮助。

In recent years,with the rapid development of national economy,the location of most high-voltage and large-capacity transformers is gradually narrowing,which directly affects peoples normal work and life,and also induces a series of noise control problems of large transformers.With the development of modern control technology,the cost of control chip is reduced,which makes active noise reduction technology widely used in transformer noise control process.Based on this,this paper takes power transformer as the main research object,and expounds the noise analysis and active noise reduction measures,hoping to be helpful.
