| 摘 要： | 本文提出了一个三重冗余的汽轮机保安系统，它且有三个安全独立的超速保护电液控制通道，三个通道的输出压力经一个三中取二液压表决器表决处理，表决结果再由一个高可靠及高响应平板式液压阀进行液压放大，最终利用这个放大了的液压信号去控制汽轮机进汽口的快关阀图３，参２

| Abstract: | This paper proposes a triple redundant safety system for steam turbine.The safety system has three independent electro-hyduaulic over-speed protection channels,and the output pressures are processed by a two out of three hydraulic voter.The voting result is then amplified by a plate-type hydraulic valve,which is of high response and reliability.Finally this amplified hydraulic signal is used to control the rapid-action-stop valve in the steam admission port of the turbine.3figs.,2refs. |
