Analysis on alarm of higher sealing oil level of generator and treatment

Abstract

Abstract:

Abstract:The often repeated alarm of higher sealing oil level of the generator in a power plant was introduced. The reason of the clogged oil return was analyzed, and it was pointed out that the reason is too small gradient of the oil return tube. The sealing oil return tube was reformed, and the hidden trouble of the sealing oil system of the generator was eliminated.

Key words: Key words:generator, sealing oil, alarm of higher oil level, clogged oil return, gradient, solution
