It is concluded that the causes of sudden vibration are oil film whirl and thermal unbalance of generator rotor resulting from interturn short-circuit and hindered winding expansion etc.
认为突发性振动原因是运行中转子的油膜涡动和匝间短路、线圈膨胀受阻等引起的热不平衡。
The main vibration reason is considered to be thermal unbalance of generator rotor.
主要原因是由转子的热不平衡引起的。
