| Abstract: | A 220 kV transformer?s on-load decomposition switch burn-out accident is analyzed, through on-site inspection and re?turned disintegration, the cause of the accident is identified as transformer internal discharge and breakdown caused by impurities in oil, the accident further development is avoided. The experience for the safe operation and technical supervision of the 220 kV trans?former is accumulated. |
