Special gas chromatograph for transformer oil analysis

SHSP-15B typeTransformer oil chromatography analyzerIt is the latest specialized gas chromatograph launched by our company for the determination of dissolved gas components in insulation oil for power use. The instrument adopts a three detector process, equipped with TCD detector and two FID detectors. With one injection, the full analysis of the content of 9 dissolved gas components in insulation oil can be completed within 10 minutes. H2, O2, and N2 were detected by TCD; Hydrocarbon gases (CH4, C2H4, C2H6, C2H2) are detected by FID1, while CO and CO2 are detected by FID2, overcoming the impact of a large amount of CO and CO2 on hydrocarbon gases, especially on C2H2. This not only shortens the detection time but also greatly improves the detection sensitivity.

The instrument adopts a dual column parallel, series thermal conductivity detector, methane conversion furnace, and dual hydrogen flame detector gas path process, and uses three signal simultaneous output technology to complete the full analysis of dissolved gas components such as H2, CO, CO2, CH4, C2H4, C2H6, C2H2 in insulation oil in one injection. It has the characteristics of * function, good separation effect, high sensitivity, good reproducibility, simple operation, low failure rate, and beautiful appearance, which can meet the needs of multi task detection and analysis of insulation oil. All performance indicators are superior to national standards and it is a user of insulation oil analysis. The.

Special gas chromatograph for transformer oil analysisPerformance characteristics:

1. The transformer gas chromatography analyzer (touch color screen) adopts * reverse control and high-precision temperature control, combined with optimized column temperature box and sampler design, providing an excellent chromatographic separation system with excellent performance

2. Automatic monitoring will be implemented for each heating zone, and the heating power will be automatically cut off when the heating zone exceeds the temperature limit.

3. It has a gas cut-off protection function. When the carrier gas pressure is below 0.1MPa, the instrument will automatically alarm and cut off the heating power supply and thermal bridge current.

4. It has parameter storage function. After the instrument is turned off, the next time it is turned on, simply turn on the main power switch of the instrument, and the instrument will automatically run in the state before the last shutdown, achieving the true "power on and use" function. Alternatively, when the power is restored after a power failure, the instrument will automatically return to the operating state before the power failure.

5. It has a fault self diagnosis function, and the instrument detects various operating parameters in real time. When the system encounters abnormalities, the microcomputer system will automatically protect the instrument.

6. The pressure stabilization process design adopted by the gas path system reduces the impact of pressure fluctuations on the detector during gas injection, thereby minimizing the influence of shock peaks on analysis and ensuring high reproducibility and accuracy of analysis results.

7. The classic two box design of the whole machine adopts a * circuit and air circuit isolation design, which is easy to operate and maintain, making the appearance of the instrument cleaner and more beautiful, and improving the safety of instrument operation.

8. Pressure gauges are used to indicate the carrier gas, hydrogen gas, and air, making it easy for operators to understand the chromatographic analysis conditions at a glance and operate.

9. The main and key components are all made of national standard components, which extends the service life of the whole machine and reduces maintenance costs.

10. The instrument undergoes sufficient debugging before leaving the factory. After arriving at the usage site, users only need to ventilate and turn on the power to use it, making the operation extremely simple.

11. The injection port, detector, and converter are all designed with modularity, making disassembly and assembly very convenient. Even those without any experience in operating chromatography instruments can easily disassemble and replace them.

12. The oversized column box makes it more convenient to disassemble and assemble the chromatographic column.
