Introduction DGA2013-1 power system dedicated insulation oil and gas chromatographruns by computer automatic control, all-keyboard operation andlarge-screen liquid crystal displayaccording 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 equipment, 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 othersystems.
1. Technical parameters 1.1Temperature control ① Temperature range Column chamber: room temperature+15℃—399℃ Vaporizing chamber: room temperature+30℃—399℃ Conversion furnace :room temperature+30℃—399℃ Thermal conductivity detector: room temperature+30℃—399℃ Hydrogen flame detector :room temperature+30℃—399℃ ②Temperaturecontrol precision: ±0.1℃ 1.2 Thermal conductivity detector ① Sensitivity: minimum detectable concentrationof hydrogen≥5μl/L ②Noise:≤0.05mv ③Drift:≤0.15mv/30min 1.3 Hydrogen flame detector ①Minimum detectable concentration of hydrocarbon≥5μl/L ②Minimum detectable concentration of CO、CO2≥5μl/L ③Noise: ≤0.05mv ④Drift: ≤0.15mv/30min 1.4Whole machine start-up time: less than 3 hours
2. Features 2.1 Computer-keyboard operation This realizes five heating zone temperature control, detector control, over-temperature protection, "zero" degree protection, air break protection and other functions, so as to protect the chromatographic column and thermal conductivity rhenium tungsten filament most effectively. 2.2 Large-screen liquid crystal display It could display a large amount of information intuitively and clearly. 2.3 Advanced chromatography process Based on only one injection and three-detectors analytical process, the analyzer greatly increases detection sensitivity of hydrocarbon gas. Doublehydrogen flame setting also reduces the detection impact caused by the gas content differences. 3.Working conditions 3.1 Normal instrument working conditions ①Environmental condition：5℃—35℃ ② Relative Humidity：≤80% ③Power supply：220V±10% 50Hz±0.5Hz ④ 3KW power provided. ⑤No strong electromagnetic interference, corrosive gas and strong shock in the surroundings. 3.2 Gas source ①Air purity: ensure the purity of carrier gas and hydrogen is more than 99.99%, the air to be used is purifiedand air generator function in dust, oil and water removal. ②Output pressure of steel cylinder relief valve: nitrogen 0.35MPa, hydrogen 0.25MPa, air 0.35MPa ③Please replace steel cylinder timely when output pressure fell below 2MPa. 3.3Ground wire To ensure personal safety and instrument performance, the instrument must be reliably linked to the land. It is suggested to bury the ground wire in the soil 1 meter below.
