冷却回転電機の軸封油供給装置。 In order to supply pressure oil to the shaft oil sealing device of a hydrogen-cooled rotating electrical machine, there is a vacuum tank that stores and depressurizes oil that is pumped through a main pipe from a separate oil supply device, and a main oil supply pipe from this vacuum tank to the shaft oil sealing device. A regular pump that supplies pressure oil via a line, an emergency pump installed in an emergency oil supply line parallel to the main oil supply line of this regular pump, and an upstream side of the vacuum tank from the main line of the oil supply system. An emergency branch pipe that branches off and connects to the emergency pump suction side of the emergency oil supply pipe, and this emergency branch pipe or emergency oil supply pipe is connected to the main pipe and the emergency pump while the regular pump is in operation. At the same time, the vacuum tank and the emergency pump are closed, and after the regular pump stops and the emergency pump is operated, a predetermined shaft seal oil pressure is maintained, and then the main pipe and the emergency pump are closed. A shaft sealing oil supply device for a hydrogen-cooled rotating electrical machine, characterized by comprising a valve that is closed and communicates between a vacuum tank and an emergency pump.
