危急遮断转速装置的校验研究

Research on the calibration of emergency trip rotational speed devices

危急遮断器可防止汽轮机超速,准确、快速追忆汽轮机撞击子的机械飞出的瞬间实际转速,保证机组安全运行。对危急遮断转速装置的校验,应该模拟现场实际情况。为撞击子传感器安装提供可靠的理论依据,是我们迫切需要解决的问题。

Emergency trip systems can prevent over-speed of steam turbines and recall the actual speeds of centrifugal stop bolts of turbines at the flying-out moments rapidly and accurately to ensure the safe operation of systems.The calibration of emergency trip rotational speed devices should simulate the actual situation in the fields to provide reliable theoretical basis for sensor installation.
