摘　　要：为明晰油流继电器断裂的裂片或脱落的部件的运动轨迹问题,针对一起发电机变压器油流继电器的软铁探针断裂故障,基于多体动力学软件和CFD软件开展裂片运动轨迹仿真,发现裂片留于管道的某个角落,不会对变压器的安全运行造成威胁。In order to find out the movement track of the oil flow relay′s broken pieces or falling parts,aiming at a soft iron probe fracture fault of generator transformer oil flow relay,based on the multi-body dynamics software and CFD software,the movement trajectory simulation of the lobes is carried out.It is found that the crack is left in a corner of the pipeline,which will not pose a threat to the safe operation of the transformer.

关 键 词：油流继电器 运动轨迹 CFD 多体动力学
