DIAGNOSTIC APPARATUS FOR AN ELECTRIC GENERATOR SEAL OIL SYSTEM

摘要

A conventional hydrogen-cooled electric generator having gland seals prevents the escape of hydrogen gas from the generator housing. A conventional seal oil system provides the gland seals with the necessary oil so as to perform their sealing function. Diagnostic apparatus is provided for the arrangement and includes a plurality of sensors which provide output signals indicative of certain parameters such as temperatures and pressures throughout the seal oil system. The output signals are provided to a diagnostic computer which, in a preferred embodiment, utilizes an expert system diagnostic routine for examining the sensor signals and deriving certain conclusions relative to the operating condition of the seal oil system. Various conclusions are additionally reached using operator-entered information from off-line sensors.
