三峡左岸5#机组推力瓦烧瓦原因分析及处理

三峡左岸5#发电机在机组运行时突然发生了烧瓦情况，对烧瓦原因进行了分析,并制定了改进措施，为今后700MW级以上巨型机组推力轴承的设计提供了借鉴。

The paper introduces the details of the thrust pad burning-out in 5# unit the Three Gorges left bank when the unit is running. The reasons of the thrust pad burning-out are also analyzed and the suggestions for improvement are presented . Some references are accumulated to the thrust bearing design of over 700MW large-scale generators.
