要約(英語): The hollow porcelain insulator is widely used in the gas-insulated power apparatus and oil-filled power apparatus. Previously, it had been thought that the aged deterioration does not occur in the hollow porcelain insulator. However, the gas leaks and oil leaks because of alkali silica reaction in the porcelain of cementing part have been reported in recent years.We experimentally verified the generation process of the alkali silica reaction by using the hollow porcelain insulator removed from the substation, and examined the inhibition method of alkali silica reaction that used the lithium nitrite. As the result, it was clarified that the alkali silica reaction occurs in the hollow porcelain insulator and the lithium nitrite is effective for inhibition of alkali silica reaction.
