Transformer Oil Chromatography Analysis and Testing Instrument for Power Generation and Supply SelectionMain technical features:

The Shanghai Suhuo Transformer Oil (Insulation Oil) Analysis Special Gas Chromatography Instrument is a multifunctional gas chromatography instrument specifically designed for analyzing the dissolved gas content in insulation oil. 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. Insulation oil analysis for users.

Performance 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.

This method is suitable for the inspection and detection of various samples such as gas mixtures, liquids, and volatile solids, but the more complex the mixture, the longer the separation time required. In the process of using a gas chromatograph, if the components of the mixture are driven by a gas or liquid mobile phase, the transformer oil chromatography analyzer passes through another solid or liquid stationary phase, and the fixed forces on each component are different, including desorption ability, adsorption ability, and dissolution ability. Therefore, there are differences in the retention time of each component in the stationary phase, which can achieve the purpose of separating the mixture. After the separation of each component, non electric conversion is carried out in the system in the order of flow direction to obtain electronic signals proportional to the concentration of the components. The system records and calculates these signals and plots them.

Transformer oil chromatography analyzerPreparation before installation:

1. Preparation before installation

(1) Studio and Workbench. There should be no flammable or explosive gases, electromagnetic fields, or electrical sparks around the studio, and the indoor air should be kept dry and well ventilated. The workbench should be level, stable, and free from strong vibrations.

(2) Power supply. The instrument uses a 220V, 50HZ AC power supply. The input line of the power supply should withstand a power greater than 2KW, and the power supply voltage should be stable. Otherwise, a voltage regulator of 3KW or more should be added, and the power junction box should have reliable contact.

(3) Ground wire. To ensure the performance of the instrument and personal safety, the instrument must be reliably connected to the earth. It is recommended to use copper mesh or copper plate to bury the grounding wire in wet soil below one meter deep. It is not allowed to use power neutral wire instead of grounding wire, and it is not allowed to connect it

On the water pipe or radiator.
