Online detection device for quality of SF6 gas in electrical equipment

The utility model discloses an online detection device for the quality of SF6 gas in electrical equipment. The online detection device comprises a direct sample feeding system, a photoelectron ionization source, a mass analyzer and a signal receiving and detecting system. The online detection device has the advantages that by detecting the pollutant content in SF6 gas in the electrical equipment by virtue of the online detection device, the problem that the total pollutant content in SF6 gas in the electrical equipment cannot be measured by virtue of an existing detection device is solved; the online detection device has the characteristics of no sample pretreatment, high detection speed and sensitivity and the like and can meet complex detection requirements on the spot.
