Title: Enclosed vertical electric rotating machine
Inventor: IMOTO HIDECHIKA
IPC: H02K9/02
Filed: 1990-06-06
Abstract: PURPOSE:To suppress pressure rise in an electric rotating machine due to soffocative high pressure fire extinguishing gas ejected at the time of fire extinguishing by disposing a pressure reducing unit in proximate to the center of the electric rotating machine and on the inside of at least a rotor coil. CONSTITUTION:Fire extinguishing gas, i.e. CO2 gas, is ejected through a gas ejection port 4 into an electric rotating machine, and an interface layer 10 between the CO2 gas and inner air is produced through centrifugal function of a rotary section 5. Fire in the electric rotating machine generally occurs at a rotor coil 6 and a stator coil 8 disposed on the inside of stator section 7, but the interface layer 10 covers the rotor coil 6 and the stator coil 8 to extinguish fire and only the inner air is discharged through a pressure reducing window 9 thus reducing the pressure in the machine. Since the pressure reducing window 9 is disposed in an inside wind tunnel 2 on the inside of the rotor coil 6 arranged in the proximity of the center of electric rotating machine, the CO2 gas is effectively concentrated at the firing part and only the air is discharged to the outside. Consequently, harmful CO2 gas is prevented from being discharged to the outside.
