摘要：

On-line monitoring technology of dissolved gas in transformer oil is one of the most effective methods for detecting the operating status of the transformer. Since Raman-based technique has obvious advantages of non-contact measurement and multi-gas detection simultaneously, it is proposed to be used in this paper. In the lab, a laser Raman spectroscopy gas analysis test platform was built. The Raman spectroscopic characteristics of the dissolved fault gases in the transformer oil was analyzed through multi-peak fitting. The wave number of 1324 cm(-1) and 2914 cm(-1) corresponds to the Raman shift spectrum of methane, and the wave number of 1469 cm(-1) and 2945 cm(-1) corresponds to the Raman shift spectrum of ethane. The feasibility of the direct detection of the fault gas in the oil by the Raman spectroscopy method is verified. Therefore, it is a potential choice to the on-line monitoring of the dissolved gas in the transformer oil based on Raman spectroscopy.
