谐波对电容器容值变化影响的试验研究

摘要

文章制定了10 kV条件下研究谐波幅值和相位、基波大小以及反映谐波和基波特性的电压方均根值、电压峰值及电压波形3个系数对电容器容值变化影响的试验方案，进行了谐波与电容器容值变化关联性试验研究。在试验研究的基础上，对试验前后电容器容值变化与谐波电压大小与相位，基波电压大小，以及反映基波与谐波特性的3个系数之间的关系进行了详细的量化分析，给出了电容器容值变化与3个系数间的定性关系。%A testing program of researching on the impact on the change of capacitor capacity value of harmonic ampli-tude and phase, the size of the fundamental wave and the voltage RMS, peak and waveform factors which reflect the characters of the harmonic and fundamental wave in 10kV is formulated in this paper.And the study of relevance be-tween harmonic and change of capacitor capacity value has been carried out.On the basis of the experimental study, this paper quantitatively analyzed the relationship between the change of capacity value and the harmonic amplitude and phase, the size of fundamental wave and the three factors which reflect the characters of the fundamental and har-monic wave before and after the test in detail, and then the qualitative relationship between the change of capacitor ca-pacity value and the three factors is given.
