Description

technical field [0001] The invention relates to a method for using an oil sample chromatographic analysis quantitative sampling device with a dust-proof plug. Background technique [0002] During the daily operation of power transformers, insulating oil is subjected to strong electric fields, electromagnetic environments, and various external environments to produce gas dissolved in insulating oil. Insulating oil chromatography is a diagnostic technique for condition assessment of oil-filled equipment . It provides effective insulation supervision for electrical equipment to ensure the safe and stable operation of electrical equipment. Specifically, gas chromatography is used to measure the component content of dissolved gas in insulating oil. The measurement results are used by power supply companies to judge whether there are latent overheating, discharge and other faults in the oil-filled power equipment in operation, so as to ensure the safe and effective operation of t...
