Combined carrier gas supply device of insulating oil chromatography on-line monitoring system

According to the combined carrier gas supply device of the insulating oil chromatography on-line monitoring system, three functions of air purification, air transmission and control and air storage are separately combined and designed, and the combined carrier gas supply device is conveniently installed in insulating oil chromatography on-line monitoring devices of different specifications and isnot limited by space. The metal powder sintering filter and the semiconductor drying device are used for dehumidifying air, purified air is stored in the air storage tank, compressed air with reliablequality can be provided, and it is ensured that the quality of the compressed air meets the chromatographic column separation requirement. The device is further provided with a gas accumulation flowmeter, and when the gas accumulation flow meter achieves a set value, the purified air is used for carrying out reverse blowing on the metal powder sintering filter, so that the system is automatically cleaned and free of maint
