Abstract
The online monitoring device for dissolved gases in transformer oil adopts advanced infrared pho-toacoustic spectroscopy technology.In response to the demand for detection instruments for dissolved gases in transformer oil in the development of China's smart grid industry,research on the detection of fault gases in transformer oil has been conducted.Through the optimal selection of spectral lines and the integrated design of the chopper filter wheel,the detection sensitivity of this detection system for CO,CO2,CH4,C2 H2,C2 H4,C2 H6,and H2 is 0.22ppm,0.03ppm,0.3ppm,0.3ppm,0.95ppm,0.1ppm,and 1.2ppm,respectively.This study has addressed the issues of transformer accidents and the resulting power outages,ensuring the long-term stable operation of China's power system.
