PURPOSE:To improve the reliability of a gas system by providing a temperature sensor and an atmospheric sensor in addition to a pressure sensor and always automatically monitoring. CONSTITUTION:A frame 1 which covers the outside of a hydrogen cooling turbine generator is formed in an airtight structure to seal hydrogen gas, and a sealing unit 3 is provided. Sealing oil is supplied from a sealing oil reservoir 4 to the gap between the unit 3 and the shaft of a rotor 2. Hydrogen gas is supplied from a bomb 6, the gas pressure is measured and indicated by sensors 5, 9. In this case, a temperature sensor 10 for measuring the gas temperature in the frame 1 and an atmospheric pressure sensor 11 are added, the output signals of these and the sensors 5 are inputted to a calculator 12, and the output signal of the sensor 9 is inputted to a calculator 13. The output signals of the calculators 12, 13 are fed to an indicating recorder 1 and an alarm generator 15, thereby indicating, recording and warning. |
