摘　　要：介绍了汽轮机控制系统中一种自容式电液执行器的结构和工作原理。由于这种执行器为一个独立的部件,有自己的油源和电液伺服系统,通过接收指令能够控制油动机的动作,具有集成度高、可靠性高、应用简便、节能、环保和耐污染等特点,为汽轮机数字电液控制系统的设计、改造提供了新的途径。The structure and working principle of a self-contained electro-hydraulic actuator for turbine control systems are being illustrated. As an independent component, the actuator has its own oil source and electro-hydraulic servo system, and can control the action of an oil servo motor according to instructions it receives. Featured by high integration, high reliability, convenient application, energy saving, environmental protection and high stain resistance, the actuator may serve as a new approach for design and retrofit of relevant digital electro-hydraulic control systems of turbines.
