摘　　要：以礼河四级复建电站装机容量为130MW,共设有4台单机容量为32.5MW的冲击式水轮机组,出线竖井规模高达281m。消防系统可靠是电站设备稳定运行及人员安全撤离的前提保障,简要介绍了电站建筑与机电设备消防灭火系统布置的概况,分析了施工洞室永临结合使用的可行性,针对无竖向封堵的高落差电缆竖井,优化提出了采用高压细水雾灭火系统辅以通风隔断措施的解决方案。The installed capacity of Yilihe Fourth Cascade Reconstruction Power Station is 130MW and there are 4 impact turbine units with a single capacity of 32.5MW.The outgoing shaft scale is as high as 281m.Reliability of fire protection system is the precondition for stable operation of plant equipment and safe evacuation of personnel.This paper briefly introduces the general layout of fire protection system for power plant buildings and electromechanical equipment,and analyses the feasibility of permanent combination of construction tunnel.Aiming at high drop cable shaft without vertical plugging,a solution using high-pressure water mist fire protection system supplemented by ventilation and partition measures is put forward.
