摘　　要：与常规水电站地面式厂房的结构形式不同,春场坝抽水蓄能电站安装层位于2294.90 m高程地面,主机层位于2253.63 m高程的地下竖井井底,高差达41.00 m,自然通风无法满足要求。因此,采用机械送风方式通过风机和风管送风至井底主机层工作面,排风通过井内、外的压力差排出井外;笔者考虑到井壁的自然吸热功能及主机层的发电设备散热、散湿,湿度过大将影响机电设备的正常运行,设置升温性除湿机对井底主机层进行温湿度调节;根据现行规范,需要对井底主机层进行机械送风及机械排烟。经上述措施,充分满足电站温湿度的控制要求并达到消防安全的目的。Different from the structure of conventional ground-type powerhouse of hydropower station,the installation floor of Chunchangba pumped storage power station is located on the ground with an elevation of 2294.90m,while the main engine floor is located at the bottom of the underground shaft with an elevation of 2253.63m and there is a height difference of 41 meters.Natural ventilation cannot meet the requirements.Therefore,mechanical air supply is adopted on the working face of the main engine floor at the bottom of the shaft through the fans and air ducts,and the exhaust air is discharged out of the shaft through the pressure difference between inside and outside of the shaft.Considering the natural heat absorption function of the well wall and the heat dissipation and dehumidification function of the power generation equipment on the main engine floor,which will affect the normal operation of the mechanical and electrical equipment,a temperature-raising dehumidifier is set at the bottom of the well to adjust the temperature and humidity of the main engine floor.According to the current regulations,the mechanical air supply and smoke exhaust are required for the main engine floor at the bottom of the well.Through the above measures,the temperature and humidity control requirements of the power station can be fully met to achieve the purpose of fire safety.
