Title:
EMERGENCY GAS HELIUM DISCHARGING DEVICE OF SUPERCONDUCTIVE ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS6077665
Kind Code:
A
Abstract:
PURPOSE:To optimize the shape and sectional area of a discharge passage by providing a discharge valve in a helium discharge passage formed in a driving machine side shaft which communicates with a liquid helium storage unit. CONSTITUTION:A discharge valve 30 is provided in an emergency helium discharge passage 25 in a shaft 13a, and an outlet 31 communicating with the exterior is formed at the end side of the passage 25. When an abnormal boiling occurs in a liquid helium storage unit 33, the discharge amount is limited in the gas helium discharge passage at the normal time. Accordingly, the pressure in the unit 33 rises. When reaching the prescribed value, the valve 30 is opened, gas helium is discharged from the outlet 31 through a thin-walled pipe 32 to the exterior of the rotor. Thus, emergency gas helium discharge passage and the valve are mounted at the drive side, and the sectional area of the gas helium passage can be increased, to smoothly discharge the gas helium.
