    • A trip oil system automatically controls the fuel shut-off valves in an industrial gas turbine. The trip oil system applies hydraulic pressure to actuate and hold open a fuel shut-off valve so that fuel flows to the combustor of the gas turbine. When the trip oil system relieves the hydraulic pressure, the fuel shut-off valve closes and stops the fuel flow to the combustor. A bank of three solenoid valves controls the application of hydraulic pressure to each fuel shut-off valve. Hydraulic fluid conduits interconnect the three solenoid valves such that no single valve by itself can relieve the hydraulic pressure applied to the fuel shut-off valve. During normal operation of the gas turbine, all three redundant solenoid valves are activated. For the trip oil system to cause the fuel shut-off valve to close, at least two of the solenoid valves must de-energize to relieve pressure to the fuel shut-off valve.
    • 跳闸油系统自动控制工业燃气轮机中的燃料切断阀。 跳闸油系统应用液压来启动并保持打开燃料切断阀,使得燃料流入燃气轮机的燃烧器。 当跳闸油系统释放液压时,燃油关闭阀关闭并停止燃油流向燃烧器。 一组三个电磁阀控制向每个燃料截止阀施加液压。 液压流体导管将三个电磁阀互连,使得单独的阀本身不能释放施加到燃料截止阀的液​​压。 在燃气轮机正常运行期间,所有三个冗余电磁阀都启动。 为了使跳闸油系统导致燃料切断阀关闭,至少两个电磁阀必须断电以释放对燃料切断阀的压力。
