摘要
目的本文通过对医用磁共振成像(MRI)设备滤波电源的故障分析,提出有效的解决方案,提升维修保养人员对核磁共振电源的保障技能。方法描述我院西门子核磁共振在使用过程中遇到的电源故障的现象,进行现场排查,发现有源滤波器的线路上互感器安装方向错误,导致MRI电源故障。结果调整有源滤波器互感器安装方向后,MRI恢复运行正常。结论滤波器安装后,在负载设备使用前需要进行调试。稳定可靠的滤波器,是MRI电源的重要保障。
【Objective】To promote maintenance personnel＇s troubleshooting skills by means of the troubleshooting analysis in filter fault of magnetic resonance imaging（MRI） power.【Methods】The power failure of our SIEMENS MRI was described in this paper.Through on-site investigation,it was found that the wrong installation direction of transformer on active power filter circuit caused the MRI power failure.【Results】After adjusting the installation direction of the transformer on the power line,MRI started working normally.【Conclusion】It＇s necessary to debug the filter before the filter and MRI were set to work.Stable and reliable filter is an important guarantee for MRI power supply.
