Adsorbent absorbs the important component of gas moisture as air insulating device, and adsorbent reaches necessary after saturation
Changed, and traditional adsorbent is installed in air insulating device closing metallic walls, absorber is connected with device interior,
When changing, it is necessary to reclaim the gas of whole section of air chamber, its gas recovery amount is more, and recovery speed is also slow, in Renewal process
In, it is necessary to the electrical equipment of more air-exchanging chamber is stopped transport, have a strong impact on the power supply of equipment, because adsorbent installation number is more, change
Duration is longer, and power off time is long, and input cost is high.
The content of the invention
It is an object of the invention to provide the online replacing options of air insulating device adsorbent, mainly solve in the prior art
It is cumbersome, change long in time limit, power off time length, the problems such as input cost is high.
To achieve these goals, the technical solution adopted by the present invention is as follows：
The online replacing options of air insulating device adsorbent, including air insulating device, be connected on air insulating device,
For pressure monitoring and it is online change the four-way valve of adsorbent, and be connected on four-way valve, the absorption for placing adsorbent
Device.Wherein, main valve of the four-way valve including being connected on air insulating device, for cutting off extraneous connection, is connected on main valve
Valve seat, and pressure gauge valve, note air bleeding valve, the inlet valve being connected with valve seat.Absorber includes being connected to the back box of inlet valve,
Filter screen installed in back box bottom, for isolating adsorbent, and the closure at the top of back box.Pressure gauge valve outlet peace
Fill the pressure gauge for monitoring air insulating device pressure.
This method comprises the following steps：
I) gas in absorber is reclaimed：Close inside main valve, air insulating device and absorber completely cuts off, gas is reclaimed and filled
Put and be connected on note air bleeding valve, start gas concentration unit, open note air bleeding valve and reclaim absorber gas.
II) adsorbent is changed to the absorber of gas recovery：Change adsorber operation：The closure of absorber is opened,
The adsorbent of saturation is taken out, qualified adsorbent is placed, and close closure.
III) gas injection is vacuumized to the absorber for having changed adsorbent：Vacuumize gas injection operation：Vacuum extractor is connected to
Note on air bleeding valve, closing presure table valve, be evacuated to standard value, keep pressure 1~2 hour, close note air bleeding valve, remove and take out true
Empty device, qualified gas is injected from note air bleeding valve, and Opening pressure table valve closes note air bleeding valve.
IV) absorber of gas injection is put into operation：Measurement water content is qualified after new gas in absorber is stood, and opens main valve.
Compared with prior art, the invention has the advantages that：
The present invention is in communication with the outside by operating inside four-way valve, cut-out air insulating device, to the absorption in absorber
Agent is changed, and adsorber volume is small, gas recovery, vacuumize, the gas injection operating time reduces significantly.This method has operation
Simply, without having a power failure, short time limit is changed, gas injection rate is few, low cost and other advantages, there is higher popularization in air insulating device field
Application value.
