摘要
讨论了光声光谱应用于实现变压器油中气体在线监测的原理。探讨了利用光激发的声波速度测量氢气含量的实现途径;在光声光谱的检测指标、技术特点等与在线色谱、在线傅立叶红外光谱进行了比较。
The principle to apply photoacoustic spectroscopy in the online monitoring of dissolved gasses in transformer oil is discussed. The way to measure hydrogen contentration with the velocity of sound excited by light is presented. The comparison between photoacoustic spectroscopy and online gas chromatography and online FTIR spectroscopy in detectable parameters and technical characteristics is made.
