| Abstract;There are contained some ones with longer worked term of 25 to 30 years in the gas circuit breakers (GCBs) under operation at present. To evaluate fair lives of these power apparatuses, here was carried out a subdivision survey on longer worked removal objected apparatuses of the double pressurized tank type GCBs, to evaluate a deterioration evaluation at their parts levels. As a result, it could be found that for their extremely deteriorated parts, packings, greases, contacts, and so on were extracted. |
