Cause Analysis and its Treatment to 600 MW Unit Temperature Thrust Bearing Shoe Raising

600MW超临界机组推力瓦温度升高原因分析与处理

During the operation of thrust bearing shoe, served as an index of malfunction, oil temperature is more effective than thrust bearing shoe temperature.

在推力瓦的运行中，油温反映故障比瓦温更有效。

Measures for lowering the thrust bearing shoe etc.

降低推力瓦块措施。

What is tested by trial in this paper is using the discontinuity of thrust bearing shoe and then limiting the error action of protection by making characteristic quantities to restrict with each other.

本文尝试用油温的突变量来描述推力瓦的故障过程，并且用多种特征量相互制约来限制保护误动。

The former has a double-layer bearing structure with small supports that make such separation between thrust bearing shoe and bearing pillow that asymmetrical temperature distribution on the thrust bearing shoe has minimum impact on the bearing pillow with a lower thermal deformation.

巴氏合金瓦推力承轴采取小支柱双层瓦的结构形式，由于小支柱将推力瓦和托瓦分开了，使推力瓦的不均匀温度分布对托瓦影响极小，不会引起较大的热变形。
