- Abstract
SUMMARY Hollow porcelain insulators are widely used in gas-insulated power apparatus and oil-filled power apparatus. Previously, it was thought that hollow porcelain insulators are not subject to aging deterioration. However, gas and oil leaks caused by the alkali-silica reaction in the porcelain where it is in contact with cementing parts have been reported in recent years. We experimentally verified the generation process of the alkali-silica reaction by using a hollow porcelain insulator removed from the substation, and examined an inhibition method of alkali-silica reaction based on the use of lithium nitrite. It was found that the alkali-silica reaction occurs in the hollow porcelain insulator and that lithium nitrite is effective for inhibition of the alkali-silica reaction.
