特徴とするタービンの前部心棒異常検出装置。A front mandrel abnormality detection device for a turbine that detects an abnormality in a front mandrel disposed at one end of a turbine rotor, comprising: a rotor-side vibration detector that detects a vibration amplitude of the front mandrel on the turbine rotor side; Vibration amplitudes are input from a tip-side vibration detector that detects the vibration amplitude of the tip of the front mandrel, the rotor-side vibration detector, and the tip-side vibration detector, and the difference between these vibration amplitudes is determined in advance. A front shaft abnormality detection device for a turbine, comprising a control device that outputs an alarm signal when a certain value is exceeded.
