要約(英語): In the SF6 gas disconnector, a loose connection and an abnormal overheating of the contact may be caused by aging and multi-frequency operation. To detect the loose connection of the disconnector, we developed the condition assessment method that used the SF6 decomposition gas. The proposal technique uses the amount of CF4 in an internal insulation gas with the operation frequency of the disconnector, and we investigated the insulation gas of the disconnector in the actual substation. When the developed method was applied for field apparatus, it was judged that five apparatuses were abnormal. Therefore, the major inspection was executed later for four apparatuses of them, and, as a result, internal abnormalities were discovered at all apparatuses.
