The present invention also provides a kind of gas-insulated switch sulfur hexafluoride gas leakage detection methods, and (1) is with doubtful
Adhesive is smeared around the doubtful leak source of the column combined electric equipment of leak source, (2) are by the bonding muzzle of closed plastic sack
Be located in the column combined electric equipment for smearing adhesive, (3) using tight twist cable to column combined electric equipment with
And closed plastic sack abutting edge is realized and is fastened and fixed, and after (4) wait for 2-3 days, closed modeling is directed at sulfur hexafluoride detecting instrument
The setting of material bag upper end can pull type detection mouth, opening rapidly can go deep into sulfur hexafluoride detecting instrument after pull type detection mouth
In closed plastic sack, (5) prove that the doubtful leak source is implicitly present in if sulfur hexafluoride detecting instrument sends out drop drop alarm
Leakage.
The advantage of the invention is that：
The present invention can more accurately easily hunt leak to sulfur hexafluoride equipment by the application of the tool, cost
It is cheap, relative to no advanced leakage detecting instrument equipment in the case of, quickly cheap preliminary judgement can be made to status of equipment.
