In other words, the in-flight cooling water system (A:) consisting of the stator winding (1), the insulated connection pipe, and the in-flight cooling water piping (15+) is constantly under pressure of 1 to 3+ cgr/CIIt. If the in-flight cooling water system is damaged due to an abnormality, hydrogen gas will leak into the in-flight cooling system through the damaged area, pass through the outlet pipe (4), and enter the cooling water tank (6).

released into the atmosphere. Maintenance and operation of rotating electrical machines-1-1
Hydrogen gas consumption is constantly monitored, and if there is a significant increase, the cause will be investigated immediately. However, if the cause is within the in-flight cooling water system (A) and the damage is relatively minor, the leakage of hydrogen gas will be much faster than normal hydrogen gas consumption (about 10 m'/day). Therefore, by means of consumption monitoring, it is not possible to detect a failure until the damage progresses and the amount of hydrogen gas consumed clearly increases. The hydrogen gas that has entered the cooling water tank (6) is only released into the atmosphere by the action of one breath caused by a slight change in the water level in the cooling water tank (6), and is not sufficiently released. Therefore, even if the in-flight cooling water system (A) ruptures 111 and there is little hydrogen leakage or discharge, hydrogen gas will accumulate in the cooling water tank (6) and the water gas concentration will explode. Damage to the in-flight cooling water system must be detected early, as it is extremely dangerous for maintenance and operation as it is possible that the concentration could reach the limit concentration. This also applies to the rotor winding in-machine cooling system (not shown).

Therefore, a hydrogen gas concentration detector was attached to the atmosphere discharge pipe (O), and a fan was used to connect the atmosphere discharge pipe (161) to the cooling water tank (
6) Attempts were made to remove the internal gas and use a hydrogen gas concentration detector to detect hydrogen gas leaking into the cooling water. However, with this method, it is easy to cause excessive air flow.
As a result, it is difficult to detect hydrogen gas when its concentration is low, and skill is required to adjust the fan air volume to provide the appropriate amount of ventilation.
Improvements were requested.
