摘　　要：在电厂现场对大功率汽轮机隔板挠度进行测量,可以为隔板刚度状态检测和安全性评定提供技术手段。介绍了高中压隔板挠度测试装置和现场测量步骤。数据采集系统由百分表、切换开关、模数转换器及计算机组成,还包括加载系统中的超压报警断电装置,确保了汽轮机隔板挠度测试过程安全,测量数据可信。Power plant on site measurement, of diaphragm deflcetions of large turbines, provides a way for evaluating the stiffness of diaphrams and therewith their safety in operation. Measuring equipment and the measuring procedure are here described. The data acquisition system eonsists of dial indicators, switches, converters and a computer, including a current cutting alarm device in case the pressure in the pressurizing system exceeds alowable values. Safety and credibility of measurements are herewith warrented.
