摘　　要：合成抗燃油以其优越的抗燃性能在大型汽轮机控制系统中得到了广泛应用。然而系统泄漏以及杂质卡涩已成为应用中的突出问题,机组的事故率也因此大大增加。在系统改造过程中,探索了减少抗燃油系统泄漏、减少机组事故跳闸率的途径。Because of its superior fire resistant property, synthetic fire resistant hydraulic oils are widely used in control systems of large steam turbine sets. But leakage and seizures caused by impurities have become striking problems in its application, causing accidental failures to occur remarkably more frequently. By way of retrofitting the system, means of reducing tripping failures and oil leakages have been probed,
