If case lid has gas leak phenomenon, it is necessary to which by case lid, counter remove is repaired or changed from cabinet；Then it is assembled into again
Cover on switch cabinet, carry out airtight test.First case cover screw to be checked or manual elbow folder are fixed on during airtight test
In the good cavity type frock of air-tightness, airtight test then is carried out to the charge valve on case lid, main method is：Bubble
Method, pressure differential method, leak detector suction gun method.
Bubble method：There is the mode of two kinds of lookup leak sources, (nitrogen or compression are empty by certain barotropic gas in workpiece to be checked
Gas) after, integrally it is put into transparent water tank, or it is breakthrough to be sprayed at position to be checked at suds, visual observations bubbling.
Pressure differential method：After certain barotropic gas (nitrogen or compressed air) in workpiece to be checked, a period of time, pressure are stood
Decline and show that the part has leakage.
Leak detector suction gun method：Workpiece screw thread to be checked or manual elbow folder are fixed in cavity type frock, then toward cavity
Filled in frock after certain malleation dielectric gas (sulfur hexafluoride gas or helium etc.), with the suction gun of leak detector at position to be checked
Moved with probe suction gun against seepage place is possible to, when leakage detection apparatus sends alarm, that is, show there is leakage herein；Treating
After inspection workpiece is separated with cavity type frock, dielectric gas is discharged into environment.
But, case cover screw or manual elbow folder to be checked is fixed on the shortcoming in the good cavity type frock of air-tightness：
Fixed and flexible is poor when output is big, speed is slow, inefficiency.
The shortcoming of bubble method is：Eye-observation, the human factor accounting of its result is larger, and the reliability of inspection result is low；
Workpiece surface, which has, after inundation gets rusty or soap stain.
The shortcoming of pressure differential method is：Stand and wait pressure change, if the time is shorter, it is impossible to accurate judged result, the time compared with
It is long, check inefficiency.
The shortcoming of leak detector suction gun method：After having checked, check that medium is discharged into working environment naturally, output is big
When, environment is contaminated, and influences inspection result, easily causes erroneous judgement.
