The present invention application method be：The first step：Sulfur hexafluoride gas cylinder is installed to gas concentration unit（1）On, it opens Sulfur hexafluoride gas retracting device；
Second step：The solenoid valve end for measuring shutdown module is forwarded to sulfur hexafluoride gas retracting device gas by Open control module Body pipeline, pressure transmitter end are forwarded to GIS inflation/deflation interfaces；
Third walks：Press display screen（5）On release button carry out bleed air operation, atmospheric pressure value is deflated to for non-breaker gas chamber For 0.315MPa, it is 0.485MPa that breaker gas chamber, which is deflated to atmospheric pressure value, by PLC programmable logic controller (PLC)s（4）Control electromagnetism Valve（2）Shutdown, then manually switch off gas concentration unit（1）Deflation air valve stops to the gas-insulating and fully-enclosed combined electrical apparatuses of GIS （7）It deflates；
4th step：Press display screen（5）On inflation button, open gas concentration unit（1）Gas-filled switching tube may be programmed by PLC Logic controller（4）Control solenoid valve（2）It opens, starts to the gas-insulating and fully-enclosed combined electrical apparatuses of GIS（7）Inflation, non-open circuit Device chamber inflated to atmospheric pressure value is 0.4MPa, and breaker chamber inflated to atmospheric pressure value is 0.6MPa, turns off solenoid valve（2）, manually Turn off gas concentration unit（1）Inflating air valve stops to the gas-insulating and fully-enclosed combined electrical apparatuses of GIS（7）Inflation；
5th step：After standing 30 minutes, third step and the 4th step are repeated；
6th step：According to the gas-insulating and fully-enclosed combined electrical apparatuses of GIS（7）Initial humidity, decision repeat the 5th step five to ten times not Deng；
7th step：Press display screen（5）Reset button so that the gas-insulating and fully-enclosed combined electrical apparatuses of GIS（7）Air chamber pressure restores Setting value；
8th step：After standing 24 hours, the gas-insulating and fully-enclosed combined electrical apparatuses of GIS are tested（7）Whether humidity meets regulatory requirements, If meeting flow to terminate, if not meeting, above step is repeated.
The beneficial effects of the present invention are：
GIS gas replacements can be carried out in the case where not having a power failure, and reduce the risk of the unreliable operation of grid equipment；Simplify GIS Gas replaces flow, shortens working hours；Rational gas pressure signal is set, opening for airflow line can be automatically controlled Logical, shutdown, ensures the stability of GIS and the personal safety of staff.
