摘要
针对电力变压器运行产生的噪音问题,从变压器的设计结构及工作原理入手,分析了噪音的形成机理。除了变压器自身产生的稳定震动之外,谐波电流、直流电流对噪声的产生影响较为明显,通过对谐波电流、直流电流产生的机理进行研究,提出采用串联电阻或串联电容的方式来降低谐波、直流电流对噪声的影响。
Aiming at the problem of noise generated by the operation of power transformer, the paper analyzes the formation mechanism of the noise from the design structure and working principle of the transformer. In addition to the stability of the transformer itself, the harmonic current and the DC current have obvious influence on the noise. The mechanism of the harmonic current and the DC current is studied. The influence of series resistance orseries capacitor is presented.
