摘　　要：水喷雾灭火系统是水电站主变压器发生火灾时的主要灭火手段,但近年来因雨淋阀误动而导致水喷雾装置误喷淋的情况时有发生。结合某水电站一起主变水喷雾灭火系统误喷淋事件,对误喷淋原因进行研究和分析,指出水喷雾灭火系统在实际应用中存在的隐患,通过改造排水阀、定期检查逆止阀、取下紧急手动阀操作手柄等措施,降低水喷雾灭火系统误动的风险。Water spray extinguishing system is the main means of extinguishing fire in the main transformer of hydropower station.However,in recent years,the water spray device mistakenly sprays due to the misoperation of the deluge valve.Combined with an accident of mistakenly spraying the main transformer water spray fire extinguishing system in a hydropower station,this paper studies and analyzes the causes of mistakenly spraying.It points out the hidden dangers of water spray fire extinguishing system in practical application.The risk of misoperation of the water spray fire extinguishing system is reduced through measures such as reforming the drain valve,regularly checking the check valve,and removing the operating handle of the emergency manual valve.
