Abstract:This paper analyzed a case of gas turbine automatic shutdown caused by the accidental fault alarm of hydraulic torque
converter at the tripping speed stage during the starting process of PG9171E gas turbine. By installing temporary pressure gauges to monitor the oil pressure in the lubricating oil main pipe of the hydraulic torque converter，as well as the oil pressure at the inlet of the pump wheel and the outlet of tlie turbine，the fault points can be accurately identified and promptly eliminated，providing reference for
similar units.
