摘要
构建了基于光声光谱技术的变压器油中溶解气体的在线监测系统,给出了光声光谱测量、气体池的设计、特征吸收频率的确定及采用超声波技术的光声测量等关键技术方法,从而利用了光声光谱技术对变压器油中溶解气体进行分析,实现对变压器故障在线监测。
The online monitoring system for monitoring dissolved gas in transformer insulation oil was built based on photoacoustic spectroscopy technique.Key technical methods were presented including the measurement of photoacoustic spectroscopy,the design of gas cell,the identification of characteristic absorbing frequency and photoacoustic measurement with ultrasonic technique.The dissolved gas in transformer insulation oil was then analyzed through photoacoustic spectroscopy technique,and the online fault monitoring of the transformer faults was realized.
