Product brief
The determination of dissolved gas content in insulating oil by gas chromatography is an effective means for power generation and supply enterprises to determine whether there are latent overheating, discharge and other faults in oil filled power equipment during operation, in order to ensure the safe and effective operation of the power grid. It is also a necessary means for oil filled electrical equipment manufacturers to conduct factory inspections of their equipment.

YGC2002 Transformer Oil Special Chromatography Instrument is a specialized gas chromatograph launched by our company for the determination of dissolved gas components in power insulation oil. The instrument adopts an advanced three detector process, equipped with TCD detector and two FID detectors. With one injection, the full analysis of the content of seven gas components dissolved in insulation oil can be completed within 8 minutes. It can be controlled by computer and remotely operated. It has the characteristics of high detection sensitivity, easy use, and compact structure.

YGC2002 networked power specific gas chromatograph features:1Full microcomputer control system, computer reverse control, one computer can control

N (N ≤ 253) chromatographs with six temperature control systems and four time programs.2The chromatograph adopts advanced technology

10/100M Ethernet communication interface, capable of remote control of instruments and remote data transmission processing and supervision.

3. The workstation is built-in with digital signal output, and the signal is directly transmitted to the computer via Ethernet cable, making it easy to operate.

4. Color LCD touch screen display, intuitive human-machine dialogue, excellent user experience.

5. The chromatographic workstation is equipped with specialized software for analyzing dissolved gases in power transformer oil.

6. The independent gas extraction system ensures that gas oscillation during analysis does not affect the analysis and is easy to operate.

7. One injection, seven component peaks appear on the same spectrum, easy to operate.8Large capacity column box with automatic rear door, can be operated

8-level program temperature rise setting, 8-channel external event time program.

9. It has a self diagnostic function for fixing obstacles, displaying the location and nature of the fault at any time, and has an over temperature protection function. If any temperature exceeds the set temperature, the heating will automatically stop.
