In recent years, China's 330KV and above voltage class oil-filled equipment has become more and more popular, and the determination of the gas content of insulating oil is becoming more and more important.
At present, the carbon dioxide elution method developed according to the DL/T450-1991 method is only applicable to the determination of oil products without acid gas, and the vacuum differential pressure method developed according to the DL/T423-91 method is also disadvantageous due to the difficulty in popularizing vacuum instruments. Limitations. With the development of China's oil quality supervision technology and the improvement of gas chromatography technology, the determination of gas content by gas chromatography has become a necessary means.
The process design of the GC-9560-HD
transformer oil chromatography system is in full compliance with the regulations of the People's Republic of China Power Industry Standard DL/T 703-1999 "Gas Chromatography for Gas Content in Insulating Oils". The machine is equipped with a highly sensitive thermal conductivity detector and a hydrogen flame ionization detector, as well as a nickel catalyst converter to achieve five gas components dissolved in the transformer oil: hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide. All measurements. Its performance meets the requirements of the gas chromatograph in DL/T 703-1999 "Gas Chromatography for Gas Content in Insulating Oils".
