摘要
通过数值计算评估了HL-2M装置磁测量传感器安装精度的要求,其中磁通环坐标(R,Z)的安装偏差要求达到±2.0mm以内,磁探针的(R,Z)偏差要求在±1.0mm以内、角度偏差在±0.1°以内。定位安装采用高精度激光跟踪仪和关节测量臂结合,设备定位精度在±0.3mm。根据不同种类的磁测量传感器的定位安装特点,优化设计了包括磁通环、磁探针阵列、逆磁同心圆等的定位结构,将HL-2M磁测量传感器的安装精度控制到在±0.5mm水平。
The installation precision order of magnetic sensors is analyzed by numerical evaluation.The R and Z coordinate error of the flux loops is within±2.0mm,and the R,Z error of the magnetic probes is within±1.0mm andθerror±0.1°.The locator devices adopt the high-precision laser tracker and the arm-measuring machine,which have a positioning accuracy of 0.3mm.According to the installation characteristics of different kinds of magnetic sensors,the location structures of sensors including the flux loops,magnetic probe arrays,diamagnetic loops,are optimized and designed.The installation accuracy of magnetic measurement sensors on the HL-2M tokamak is controlled within 0.5mm.
