液压传动技术在电力系统中的应用及展望

Application and Perspective of Hydraulic Technology in Electric Power System

简述了电力系统的构成及其功能,介绍了油压传动技术在电力系统中一些成功应用的实例,包括汽轮发电机组的油润滑系统及数字电液控制系统、大型电力变压器的排油注氮消防系统等。展望了水压传动技术在电力系统中的应用可能性,包括发电环节的抗燃油替代、输电环节的输电线路山火水基型扑救、变电环节的变压器水压消防、配电环节的电力电缆敷设区域细水雾灭火,以及用电环节的重要电力场所水消防隔幕等。

Composition and function of electric power system is briefly described, Examples of oil hydraulic applied to electric power system successfully which includes lubrication system of turbine generator, digital electro- hydraulic control system of turbine generator, oil evacuation and nitrogen injection equipment of transformer etc. are introduced. A vision of application probability of water hydraulic in all the procedures of electric power system is carried, which consist of substitute for fire-resistant oil during generation, water-based transmission line forest fire extinguishing during transmission, transformer fire-fighting during transformation, water-mist fire put-out of electric cable during distribution, and water curtain of major electric sites during consumption.
