摘　　要：介绍了无功补偿电容器组发生"群爆"故障的几种不同案例,不同原因的"群爆"具有不同的故障特征,通过分析揭示了谐波涌动、单台电容元件的贯穿性击穿、开关断口重燃、人为因素、熔丝保护和继电保护整定等方面存在的问题,提出了相应的预防措施。Several different cases of reactive compensation capacitor units occurring ＂group explosion＂ faults were described.The group explosions with different causes had different fault characteristics.The problems existing on the aspects of the harmonic spouts,the penetrative breakdown of each capacitor element,the switch fracture reigniting,human factor,fuse protection and relay protection setting were revealed by analyzing,and the corresponding preventive measurements were proposed.
