In order to improve the reliability of large oil-immersed power transformers,the frequency domain spectroscopy for oil-immersed transformer insulation condition and aging diagnosis was introduced,a domestic 220 kV transformer was measured using FDS methods,and the tan δ-f curves of the transformer insulation system before and after maintenance were obtained and compared.
为了提高大型油浸式电力变压器的运行可靠性,提出了基于频域谱技术进行油浸式变压器绝缘状态及老化诊断的方法,利用该方法对国内某220kV变压器进行了测量,得到了其检修前后绝缘系统的介损频率特性曲线,并将频域谱测量方法与预防性试验数据进行了对比,验证了二者在变压器电容测量上的一致性。
