摘　　要：为检验变压器水喷雾消防设计过程中水雾喷头对保护对象的覆盖情况和提升灭火效果,本文以国内某在建抽水蓄能电站为例,详细介绍了变压器水喷雾消防系统的设计过程以及水喷雾包络线计算原理。根据变压器火灾的特点以及水喷雾消防系统动作原理,本文提出了变压器绝缘子根部专门设置喷头进行保护的方法,以及水喷雾灭火系统联动时,打开雨淋阀前先开启主泵,用主泵运行后的反馈信号来开启雨淋阀的优化建议。In order to test the coverage of water spray nozzle on the protected object as well as improving the fire extinguishing effect in the design process of transformer water spray-fire fighting system,taking a pumped storage power station under construction in China as an example,this paper provides a detailed introduction of the design process of transformer water spray-fire fighting system,and the calculation principles of water spray based on its envelope curve.Adaptive to the performance of trans formers in the fire and based on the operation principle of water spray-fire fighting system,a novel approach by specially setting the water spray nozzle at the root of the insulator for protection is proposed in this paper.Moreover,an optimization suggestion is put forward,which is to open the main pump before the deluge valve is opened,so that the feedback signal of the main pump can be used to open the deluge valve,when the water spray-fire fighting system is linked.
