摘　　要：介绍几例火电厂辅机变频器故障事故,从多个角度对变频器事故原因进行分析,指出变频器采购验收不严、安装质量差、参数和逻辑设置不合理、检修维护不到位、事故预案不完善等因素是导致变频器事故发生的主要原因,并提出了预防变频器事故的可行性方法。Based on the simple introductions of some auxiliary converters for thermal power generating units in Hunan province, the possible causes are discussed form different aspects. And it is concluded that unreasonable procurement and acceptance, wrong fixing mode, bad parameter settings, deficient repair and maintenance, imperfect construction design are the major causes for the converter accidents. Moreover, the corresponding countermeasures against the converter accidents are given .
