Introduction: In order to meet the needs of power system analysts who need to carry instruments to the fault site away from the laboratory for transformer oil analysis, our company has designed a GC-9760A transformer oil special portable chromatograph, which integrates all components such as computer and gas source. Together, the number of parts of the entire system is compressed to 2 pieces, which makes it truly portable. The instrument adopts the classic three-detector process to complete the analysis of the contents of seven gas components such as H2, CO, CO2, CH4, C2H4, C2H6 and C2H2 dissolved in the insulating oil in one injection. If necessary, The content of O2 and N2 can be detected. Executive Standard: GB/T 17623-1998 "Gas Chromatographic Determination of Dissolved Gas Components in Insulating Oils" GB/T 7252-2001 "Guidelines for Analysis and Judgment of Dissolved Gases in Transformer Oils" DL/T 703-1999 "Insulation Gas chromatographic determination of gas content in oil Technical Parameters: Detection range and detection limit (in μL/L): Component: Detection range H2: 2-10000 CO: 2-50000 CO2: 2-50000 CH4: 0.1-2000 C2H4: 0.1-2000 C2H6: 0.1-2000 C2H2: 0.1-2000 Detector specifications: Thermal Conductivity Detector (TCD): Hydrogen Flame Ionization Detector (FID) Semi-diffused structure: cylindrical collector structure design, quartz nozzle, extremely high response The power supply adopts constant current control mode: automatic ignition; stabilization time: ten minutes Sensitivity: ≥2500mV•ml/mg (n-hexadecane/isooctane) Detection limit: ≤8×10-12g/s (n-hexadecane/isooctane) Baseline noise: ≤20μV Baseline noise: ≤2×10-13A Baseline drift: ≤100μV/30min Baseline drift: ≤2×10-12A/30min Linearity: ≥104 Linear: ≥106 Temperature control indicators: Oven: 8 ° C ~ 400 ° C ± 0.1 ° C at room temperature Hydrogen Flame (FID) Detector: 8 ° C ~ 400 ° C ± 0.1 ° C at room temperature Thermal Conductivity (TCD) Detector: 8 ° C ~ 400 ° C ± 0.1 ° C at room temperature Ni catalyst converter: 8 ° C ~ 400 ° C ± 0.1 ° C at room temperature Dimensions: 380*450*180mm Weight: <15kg Power supply: AC220V±10 50Hz
