Analysis of Failure Cases of High Voltage Export Insulation Joint Weld Leakage in Natural Gas Station
This article analyzed the reasons for the leakage of insulation joint welds in a certain station,and studied its failure mechanism.The leakage cause of the insulation joint was analyzed using macroscopic analysis,non-destructive testing,microscopic physical and chemical performance analysis,insulation resistance testing,electrical insulation strength testing and other methods,and the cause of the leakage of the insulation joint was determined,providing technical support for the safe opera-tion of natural gas stations and experience for preventing similar situations.
