摘要： A diagnosis device for diagnosing loosening of a stator core of a rotary electrical machine. The diagnosis device has: excitation means for vibrating the stator core in the radial direction; vibration detection means for detecting the vibration of the stator core in the radial direction; means for frequency-analyzing an output signal of the vibration detection means that detects vibration generated in the stator core when the stator core is vibrated by the excitation means so as to extract a measurement natural vibration mode of the stator core in a circular ring natural vibration mode; means for estimating a circular ring natural vibration mode of the stator core from shape data of the stator core; and means for determining a clamping state of the stator core by comparing the measurement natural vibration mode and a determination criterion obtained based on the estimated natural vibration mode.

摘要： According to one embodiment, a seal oil feeding apparatus includes a hydrogen detraining tank, a float trap tank, and an air detraining tank. The hydrogen detraining tank is configured to collect and reserve seal oil that has flowed out to the inside of a housing from a sealing unit. The float trap tank is provided integrated with the hydrogen detraining tank in horizontally, and is connected to the hydrogen detraining tank, so that the liquid level of the seal oil becomes substantially the same as the height of the hydrogen detraining tank. The float trap tank includes a float valve. The air detraining tank is placed at a position lower than the hydrogen detraining tank and float trap tank, and reserves seal oil that has flowed out from the float valve.
