摘　　要：介绍了一种新型汽轮机高压遮断及超速限制装置,以及应用于该装置上的一种高频电磁截止式换向阀的结构及工作原理。在虚拟仿真平台建立了该装置的数字化孪生模型,并且模拟在汽轮机各种工况下该装置需要完成的相关动作。结果表明:该新型汽轮机高压遮断及超速限制装置具有良好的可靠性和较好的动态特性。The structure and working principle of a high-frequency electromagnetic cut-off directional valve applied to a new type of high-pressure trip and overspeed limit device for steam turbine were introduced. A digital twin simulation model of the device was established through virtual simulation platform, and the relevant actions required by the device under various working conditions of the steam turbine was simulated. Results show that, the new type of high-pressure trip and overspeed limit device for steam turbine has good reliability and dynamic characteristics.
