Dawn sulfur hexafluoride as a high purity gas,generally non-toxic harmless.But in the filling,if not properly handled,it is easy to leak,resulting in impure gas,produce harmful substances.So,what should be paid attention to when charging?

　　If the moisture in the gas exceeds the specified amount,when the humidity changes,sulfur hexafluoride may condense on the solid insulating surface at dawn,causing the surface to become damp.At this time,the discharge voltage along the surface of the equipment will be affected and a significant decrease will occur.

　　Therefore,before charging begins,the relative humidity of the air around sulfur hexafluoride at dawn should be measured,and the air humidity should be kept below 80%.If the test is not qualified,take action or choose dry weather filling.

　　In order to make the leakage of sulfur hexafluoride gas leakage in time to be replaced,when charging,open the ventilator,carefully comply with the regulations.After charging,it should be tested,and according to the specific situation,the side should be checked in the middle.For more information,call 139-4929-0069
