摘要
文章介绍了LCZ40-6.77/0.98/0.45型汽轮机危急遮断系统的工作原理,并对汽轮机危急遮断系统的故障进行了分析概括,得出原因为调整螺栓经过加热后产生了形变,从而导致了汽轮机机械超速出现误动,为同类型机组以及类似故障的处理提供了一定的指导意义。
This paper introduces the working principle of LCZ40-6.77/0.98/0.45 type emergency blocking system of steam turbine,and analyzes and summarizes the faults of the emergency blocking system of steam turbine,thus,the misoperation of turbine machinery overspeed is caused,which provides some guidance for the treatment of similar units and similar faults.
