摘　　要：针对某换流站一组500 kV并联交流滤波器组中多台同型号额定电压为7.34 kV的滤波电容器故障情况,结合返厂解剖情况进行了细致分析,判断是由于设备本身存在问题而导致故障,并提出了对同型号在运行电容器组的事故预防措施及相关建议。In this paper, for the fault of several sets of same type of filter capacitors at 7.34 kV in a set of 500 kV parallel AC filter bank of certain substation, and combined with return to factory disas- sembled, detailed analysis and judgment have been carried out. It is concluded that the fault is due to the equipment itself, the corresponding prevention measures and suggestions on the same type of capacitors in the operation are proposed.
