摘　　要：对某M701F3燃气-蒸汽联合循环机组启动过程中凝汽器真空度急剧下降的原因进行了分析,结果表明:低压缸冷却蒸汽管道安全阀是导致凝汽器真空度下降的主要因素,并提出了应对预防措施,为同类型机组故障分析提供了技术参考。By analyzing the reasons leading to the fast decline of condenser vacuum in an M701 F3 gassteam combined cycle unit during start-up process,the problem was found to be caused mainly by the relief valve in the low-pressure cylinder cooling steam pipeline,and subsequently corresponding countermeasures were put forward,which may serve as a reference for trouble shooting of similar units.
