为减轻水电站运行人员和检修人员的工作量 ,降低运行成本 ,研制了大型水轮机调速器逻辑式电液调节系统 ,系统由插装阀、数字阀等元件组成 .文中介绍了系统的构成原理、系统特点及静动态性能检测结果 ;指出了用该系统取代传统的主配压阀式结构 ,具有结构简单、制造成本低、抗污染能力强等优点 . In order to reduce the workload of operators and maintenance personnel and to reduce the operating cost, a logic electro-hydraulic control system for large hydraulic turbine governor was developed.The system consists of cartridge valves, digital valves and other components.In this paper, the principle, System characteristics and static and dynamic performance test results; pointed out that the system to replace the traditional main pressure valve structure, with a simple structure, low manufacturing costs, anti-pollution ability and so on.
