Profile
YJJ-208 Power system Dedicated Insulation Oil and Gas Chromatography Analyser Manual runs by computer automatic
control, all-keyboard operation and large-screen liquid crystal display according to the requirements of power system
«dissolved gas component determination in insulation oil (chromatography)» ,and is characterized by high-precision
temperature control, stable and reliable performance, high sensitivity, good reproducibility and so on.
The analyzer adopts double-pillar parallel shunt system ,equipped with TCD, double FID and methane conversion oven, and could achieve total analysis of nine components (H2,O2,N2,CH4, C2H2,C2H4,C2H6,CO, CO2)
of dissolved gas in insulation oil by one time. The analyzer can be employed for internal fault detection of power system oil
and gas equipments, cooling medium analysis of hydrogen-cooled generators, impurity analysis of sulfur hexafluoride,
the boiler flue gas analysis, gas analysis and environmental monitoring analysis. Due to its employment not only for special analysis,
but also for general analysis, the analyzer becomes the most effective gas analytical instrument in petroleum, chemical engineering,
mining and other systems. Application YJJ-208 adopts dissolved gas chromatorgraphy analysis system, runs by computer automatic control,
