摘　　要：针对Definition型双源64层CT系统断电后无法开机的故障案例,采用故障树分析法,通过故障现象确定CT系统供电电路故障,再根据设备启动流程及电路原理逐级查找出1个交流接触器和1个继电器共两处故障点,最终更换损坏配件排除故障。Aiming at the fault case that the Definition dual-source 64-slice CT system cannot start up after power failure, the fault tree analysis method was adopted to determine the fault of power supply circuit of CT system through the fault phenomenon. Then according to start-up flow and circuit principle of the equipment, two fault points, one AC contactor and one relay, were found out step by step, and finally the damaged parts were replaced, and the faults were removed.

关 键 词：双源CT 故障树分析法 交流接触器 继电器 维修
