Abstract

PURPOSE:To surely detect the abnormal consumption of hydrogen gas by calculating the hydrogen gas consumption from the data before and after the sealing of the hydrogen gas by using the signals for the temp. in a turbine generator, the pressure therein, atmospheric pressure and hydrogen gas sealing valve. CONSTITUTION:The signals from the interior temp. sensor 33, interior pressue sensor 31 and atmospheric sensor 32 of a turbine generator 1 and the open-close state signals of a hydrogen gas sealing valve 22 are inputted via an inlet circuit 40 to an arithmetic processing circuit 41. In the circuit 41, the hydrogen sealing time is detected and from the data just before the sealing (after consumption) and the data at the previous sealing, the hydrogen gas consumption is calculated, and when any abnormal consumption is detected, it is displayed 42 or an alarm is outputted 42. Thereby, the abnormal consumption of the hydrogen gas is detected surely.
