防飞逸措施
protective measures againt runaway
fong fely}euosh-防飞逸措施(proteetive measures against:un-away)为防止机组转速过度升高而采取的措施。机组事故甩负荷的同时，调速系统发生故障使导叶不能及时关闭，机组将会发生转速的过度升高，甚至达到水轮机飞逸转速，时间过长会使机组转动部分产生不同程度的损坏。防飞逸措施有3种:①在引水道的进水口设快速闸门或蜗壳前设进口间。②在水轮机调速器中采用过速限制器。过速限制器的工作原理是当机组转速升高至某一预先设定值而导叶不能关闭时则切断主配压阀与导叶接力器间的油路，直接把压力油引人导叶接力器的关闭腔使导叶迅速关闭。为了使大型机组导叶接力器或调速环故障也能关闭导叶，可在每个导叶上装设由过速限制器动作的单独的事故接力器。过速限制器的油源可以引自相邻机组的油压装里或设里专用的事故油压装里。过速限制器还应有可靠的备用压力油源。③在机组本体的设计中利用作用于导叶上的水力矩或附加一些其他作用力使得在机组事故甩负荷且调速系统故障时实现导叶的自关闭。还可以采用制动叶片来限制机组转速的过度升高。正常运行时这些制动叶片处于转轮体内，转速上升到某一定值后张开，增加制动力矩来限制转速升高。
