电力绝缘气体SF6红外光谱的小波去噪方法

摘要

将小波软阈值去噪方法应用在电力绝缘气体SF6的红外光谱去噪中。实验表示，这种方法可以有将地去除红外光谱信号中的噪声并保留光谱的特征信息，将为基于光谱分析的电气设备故障诊断研究打下基础。%In this paper, the denoising method of Wavelet soft threshold is used in infrared spectra of power insulated gas SF6.Experiments indicated that this approach can be to remove the noise signal in infrared spectrum and reserve the characteristics spectrum peaks,which should make foundation for fault diagnosis of electrical equipment.
