摘要：PURPOSE:To facilitate confirmation of trip function by storing/displaying the overspeed signal level upon function of a function confirming overspeed switch in a turbine overspeed trip while providing an interlock means. CONSTITUTION:Speed signals Na-Nc from the speed detecting section 100 in a turbine 5 are fed through adders 36a-36c to overspeed switches 30a-30c. Upon reception of overspeed signals from more than two of said switches 30a-30c, an overspeed trip circuit 31 will function a master trip solenoid 32 to trip the turbine. In order to confirm the function, test switches 35a-35c are turned on to provide the setting signal of a bias setter 34 to the adder 36 while to provide the overspeed signal 51 and operating signal 52 to a memory 37 and to display the overspeed signal on a display 38. Here, the solenoid 32 will never function because of interlock means.
