摘　　要：对于低水头大容量轴流转桨式机组,在常规设计中通常以设置事故油罐的方式来防止调速器压力油罐失压时导致的机组飞逸。文章首先从设置事故油罐的必要性,分析事故油罐在防飞逸措施中所起的作用,并说明设置该装置的优势及弊端,进而从技术上论证替代事故油罐的有效措施,并最终选用设置直流事故油泵代替事故压力油罐。For low water head and large capacity axial flow feathering unit,it commonly installs fault oil tank to avoid unit running away caused by pressure oil tank decompression of speed governor,the paper firstly analyzes the effect of fault oil tank for avoiding running away measure from necessity of setting fault oil tank,then it demonstrates effective measure to replacing fault tank technically,thus finally selects direct current fault oil pump replacing fault pressure oil tank.
