's.
Moisture predominantly detects index as SF6 gases, larger to SF6 gas-insulated performance impacts, works as moisture
When too high, may cause SF6 gases decreasing insulating or moisture in vessel surface direct liquefaction, therefore charger
Measurement of moisture content of gas has strict control standard in handing-over or prerun code, therefore controls the moisture of SF6 gases in GIS device
Content has great importance.And the existing drying system used exist intelligence degree it is low, operation inconvenience, volume it is larger, dry
The problems such as dry speed is slow, drying effect is bad.
The content of the invention
The purpose of the present invention is the shortcomings that overcoming above-mentioned prior art, there is provided it is a kind of simple in construction, it is easy to operate, and it is reliable real
Sulfur hexafluoride Quick drying system.
The present invention is achieved through the following technical solutions：
Sulfur hexafluoride Quick drying system, including first gas surge tank, second gas surge tank, the first vavuum pump,
Two vavuum pumps, booster pump, drier, pressure gas source, magnetic valve D1, magnetic valve D2, magnetic valve D3, magnetic valve D4, magnetic valve
D5, magnetic valve D6；Described magnetic valve D2 connects exhaust outlet by pipeline one end, and the other end is sequentially connected booster pump, first true
Empty pump, magnetic valve D4, magnetic valve D5, the second vavuum pump, first gas surge tank, magnetic valve D6, magnetic valve D1, magnetic valve D3,
Magnetic valve D2 forms loop；Magnetic valve D4 towards magnetic valve D5 one end are sequentially connected second gas surge tank, drier is followed by
Enter magnetic valve D1 towards magnetic valve D6 one end；Described pressure gas source by pipeline access magnetic valve D1 and magnetic valve D3 it
Between.
As the improvement of such scheme, in addition to pressure sensor, dew point transducer；Described pressure sensor is set respectively
Put on drier and second gas surge tank；Described dew point transducer is separately positioned on first gas surge tank and pressure gas
The exit in body source.
As the improvement of such scheme, in addition to PLC, described PLC is used to control first gas to delay
Rush tank, second gas surge tank, the first vavuum pump, the second vavuum pump, booster pump, drier, pressure gas source, magnetic valve D1,
Magnetic valve D2, magnetic valve D3, magnetic valve D4, magnetic valve D5, magnetic valve D6 and the information to pressure sensor, dew point transducer
It is acquired.
As the improvement of such scheme, described first gas surge tank, the volume of second gas surge tank are 5L.Dry
Internal system pressure scope is 250-300Kpa.
As the improvement of such scheme, described first gas surge tank, the volume of second gas surge tank are 12L.It is dry
Drying system internal pressure scope is 300-600Kpa.
The invention has the advantages that：Drying efficiency is fast and safe and reliable, and automaticity is high, compact-sized letter
Single, production and running cost are low.Advantage carries out gas drying to be directly connected to SF6 gas inflateds equipment, and traditional method is handle
All gas is first fully drawn out coming, and after equipment is dried, is re-filled with new SF6 gases, cycle length, expends many SF6
Gas.Therefore this method has bigger advantage.
