| Abstract: | The development history of SF6 gas detection technology, SF6 gas decomposition mechanism, common detection methods and the relationship between product and the type of insulation are reviewed. M eanwhile it is proposed to use SF6 gas decomposition component ratio to identify the type of defect, and then to do the fault diagnosis and condition assessment for equipment internal insulation. Finally, it is pointed out that the next step is to solve the problems in combination with the latest research progress. |
