Transformer oil system

      Huaai Chromatographic Analysis Technology Co., Ltd. the new launch a dedicated to power with insulating oil dissolved gas component content determination of special gas chromatograph, the instrument uses advanced three detector processes, with TCD detector and a FID detector and a, 7 minutes can complete insulation of 8 kinds of gases dissolved in oil group total analysis of the content of the GC-9560-HD transformer oil exclusive chromatograph. The H2 and O2 were detected by TCD; hydrocarbon gases (CH4, C2H4, C2H6, C2H2) detected by FID1, CO and CO2 were detected by FID2 and overcome the influence of large amount of CO and CO2 on hydrocarbon gas, especially the influence of C2H2 and shorten the detection time, at the same time also greatly improve the detection sensitivity.
