HCGC-9800 chromatographic analysis system

Detailed introduction:

To meet the needs of popularizing transformer oil chromatographic analysis in the power industry, Shenzhen Huachang Haitai Technology Co., Ltd. has launched a high-performance and economical power system specific chromatographic analysis system——HCGC-9800Dissolved Gas Chromatography Analysis System for Transformer Oil.

Main features:

1．Instrument operation Analysts only need to inject injections and samples, combined with simple computer operations, to print and analyze-The results and fault diagnosis are easy to operate.

2．Advanced analysis process

Suitable for transformer oil and gas analysisHC-TOGAP-1Single column analysis process;

Developed by Shenzhen Huachang Haitai Technology Co., LtdHC-TOGAP-1Single column analysis process, using patented technology from Huachang Haitai Company, can be in8Completely separate transformer oil within minutes8Dissolved gas components:H2、O2、CO、CO2、CH4、C2H4、C2H6、C2H2This process greatly improves the detection sensitivity of hydrocarbon gases and enhancesCO、CO2The conversion efficiency has been expandedCO、CO2The linear range. Excellent separation performance（R>1.5）SatisfyGB/T 7252-2001requirement.

3． Chromatograph host

3.1 Column box, converterFID、TCDThe temperature control adopts a single-chip digital display system with over temperature protection function.

3.2 The thermal conductivity cell adopts high ohm rhenium tungsten wire, and the measurement circuit has amplification function. Greatly improvedTCDSensitivity detection. When the sensitivity meets the requirements, the bridge current is greatly reduced, thereby extendingTCDservice life.

3.3 The hydrogen flame ionization detection circuit adopts a high-performance integrated block amplification circuit, which increases stability and reliability.

3.4 sensitivity

TCD：S≥2800mv.ml/mg（C6H6）

FID：Mt≤1×10^-11g/s

Measurable concentration in transformer oil:

H2＜5μL/L

C2H2＜0.1μL/L

CO＜5μL/L

CO2＜10μL/L

Meet national standardsGB/T7252-2001The requirements.

3.5 stability 60minwithinBaseline stability

3.6 Temp Accuracy ±0.1℃

3.7 Temperature range Above room temperature10℃~400℃

4． Chromatography workstation

The system adopts Huachang Haitai CompanyHCW-3000The type chromatography workstation achieves full automation of data processing, realizing paperless modern database management for chromatographic data, chromatograms, and data, equipment, etc. for ten projects of transformer oil quality detection.

The fault diagnosis system can diagnose the type, degree, location, and development trend of faults in transformer operation based on chromatographic data.
