摘　　要：针对HL-2M装置可拆卸的环向场(TF)线圈结构,在“D”形TF线圈外侧上、下两端分别采用水平的预紧机构对TF线圈实施预紧,使TF线圈在大电流承受较大电磁力的情况下,与TF线圈连接螺栓的预应力一起保证连接面不发生分离。由于同步性和一致性的要求,该系统采用液压同步顶升机构,并且采用压力传感器实时检测该预应力值,保证TF线圈在整个放电实验阶段的安全,为HL-2M装置整体的安全提供保障。According to the detachable toroidal field(TF)coil structure of HL-2M tokamak,horizontal preloading mechanism is adopted to preload the TF coil at the upper and lower ends of the"D"shaped coil.When the TF coil carries large current and endures large electromagnetic force,the preload and prestress of TF coil connecting bolts can ensure that the connection surface does not separate.Due to the requirements of synchronization and consistency,the system adopts hydraulic synchronous lifting mechanism,and uses pressure sensor to monitor the preload value in real time.The system ensures the safety of TF coil in the whole discharge experiment stage and provides the overall safety of HL-2M tokamak.
