Dissolved Gas System Analyzer

Transformer oil sample analysis is a useful, predictive, maintenance tool for determining transformer health. Along with the oil sample quality tests, performing a dissolved gas analysis (DGA) of the insulating oil is useful in evaluating transformer health. The breakdown of electrical insulating materials and related components inside a transformer generates gas within the transformer. The identity of the gas being generated can be very useful information in any preventive maintenance program.

SXQS Power system Dedicated Insulation Oil and Gas Chromatography Analyzer 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.

SXQS adopts dissolved gas chromatorgraphy analysis system, runs by computer automatic control, all-keyboard operation and large LCDscreen 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 etc.

It 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.  It 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.
