Research on on-line monitoring system of transformer insulating oil fault gas based on laser photoacoustic spectroscopy

研制基于半导体激光器光声光谱技术的变压器绝缘油故障气体在线监测系统,替代传统的油色谱测量和传统的光声光谱油气测量装置。相比传统技术测量装置,激光光声光谱变压器绝缘油故障气体在线监测系统具有使用寿命长、维护量低、测量无交叉干扰及重复性好等优点,可在实际在线监测中提供更准确、及时的预警机制,从而带来可观的经济效益。

An on-line monitoring system of transformer insulating oil fault gas based on the photoacoustic spectroscopy of semiconductor laser is developed,which can replace the traditional measuring device of oil spectrum and photoacoustic spectrum.Compared with the traditional measuring device,the on-line monitoring system of the transformer insulating oil fault gas of laser photoacoustic spectroscopy has the advantages of long service life,low maintenance,no cross interference and good repeatability in measurement.It can provide more accurate and timely warning mechanism in the actual online monitoring,and brings considerable economic benefts.
