摘要
It is a hydrogen-cooled generator (10) with a system for diagnosing of problems in connection with a seal oil system is provided. Includes a shaft (14) with a turbine end (30) and a (collector) end (32); a about the shaft (14) on the turbine end (30) arranged around the first shaft seal (16); a about the shaft (14) on the (collector) end (32) arranged around the second shaft seal (16); a first set of sensors (22a, 22c) for measuring of seal oil - pressure differences by means of two shaft seals; a second set of sensors (24a, 26a) for measuring of seal oil - temperature differences over two shaft seals (16); a third sensor (34a, 34b) for measuring a water material for strength (18) seal oil - flow rate; and a system for analyzing of at least two sensors the collected data (48), the shaft seals (16) in order to diagnose.
