摘要
汽轮机真空监测设备的配置和校验各个电厂差异较大,压力变送器检定规程(JJG882—2004)中也没有针对真空监测设备的规范说明,而电厂汽轮机真空是涉及汽轮机安全运行和经济性分析的重要参数,有必要对其进行规范。研究和讨论电厂汽轮机真空监测设备的配置和校验方法,提出真空检测设备校验的量程修正方法。
For the configuration and calibration of steam turbine vacuum monitoring equipment,there are differences among different power plants.Verification regulation of the pressure transmitter（JJG882-2004） has not stipulated the standard procedure for vacuum monitoring devices.Steam turbine vacuum is an important parameter for safe operation and economic analysis.It is necessary to regulate and standardize calibration practice and set up standard.The steam turbine vacuum monitoring equipment configuration and verification methods are studied and discussed.It is expected to be of certain reference value and guiding significance.
