Model Dga2013-1 Oil Dissolved Gas Tester, CE& ISO Standard, Reasonable Price

Model NO.:Model DGA2013-1 Colour:Any
Model DGA2013-1 Transformer Oil Dissolved Gas Analyzer, CE& ISO standard
I.Introduction:

DGA2013-1 Power system Dedicated Insulation Oil and Gas Chromatography Analysis System 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.

2.Main performance characteristics

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. Double hydrogen flame setting also reduces the detection impact caused by the gas content differences.

3.Working conditions

3.1 Normal instrument working conditions

Environmental condition:5ºC—35ºC
Relative Humidity:≤80%
Power supply:220V±10%  50Hz±0.5Hz
3KW power provided.
No strong electromagnetic interference, corrosive gas and strong shock in the surroundings.

3.2 Gas source

    Air purity: ensure the purity of carrier gas and hydrogen is more than 99.99%, the air to be used is purified and air generator function in dust, oil and water removal.
    Output pressure of steel cylinder relief valve: nitrogen 0.35MPa, hydrogen 0.25MPa, air 0.35MPa
    Please replace steel cylinder timely when output pressure fell below 2MPa.

3.3 Ground 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.
