On-line Purification Technology of SF6 Gas

In order to improve the stability and safety of electrical equipment operation , SF_６?gas purification technology was studied．The pressure state of SF_６ gas is collected through the state detection process．The collection results enter the background display interface through the datatransmission link．The current status trend of SF_６ gas instrument is analyzed according to the historical data curve , and the function of early warning and triggering SF_６ gas purification control is realized．In the process of SF_６ gas purification treatment , the high-pressure liquefied SF_６ liquid is converted into low-pressure gas and transferred to the purification treatment unit．The impurities are absorbed by the adsorber , and then the tail gas in the cold container of the cryogenic separation unit is extracted by the power unit．After cooling treatment , the tail gas is stored in the gas storage tank and transferred to the cylinder through the cryogenic liquid pump．On this basis , the separation technology is used to optimize the purification effect according to the difference between the gas ignition point and the boiling point．The experimental results show that the purification effect of this technology conforms to the relevant national standards , and can significantly reduce the frequency and cost of electrical equipment maintenance．
