摘要:
为探究不同障碍物遮挡条件下室内变电站消防系统的灭火有效性，搭建全尺寸110 kV封闭空间变压器灭火测试系统，利用高压细水雾系统和压缩空气泡沫系统（CAFS）开展灭火实验。通过分析2种灭火系统的灭火过程、灭火时间、空间温度分布、热辐射强度等关键参数，研究不同障碍物遮挡条件下的灭火有效性。研究结果表明：CAFS在灭火时间和冷却效率上明显优于高压细水雾系统，但在隔绝热辐射方面，高压细水雾系统的效果更好；障碍物的遮挡比会显著影响高压细水雾系统和CAFS的灭火效率，且灭火效率与障碍物遮挡比呈负相关关系，其中障碍物遮挡比对CAFS灭火效率的影响尤为显著。研究结果可为室内变电站消防系统优化设计提供参考，保障变电站的正常运行。
Abstract:
To investigate the fire extinguishing effectiveness of fire protection systems for indoor substation under different obstacle occlusion conditions,a full-scale test system of fire extinguishing for 110 kV enclosed transformer was established,and the fire extinguishing tests were carried out using the high-pressure fine water mist and compressed air foam systems (CAFS).By analyzing the key parameters such as the fire extinguishing process,fire extinguishing time,spatial temperature distribution,and thermal radiation intensity of two fire extinguishing systems,the fire extinguishing effectiveness under different obstacle occlusion conditions was studied.The results show that the CAFS system significantly outperforms the high-pressure fine water mist system in terms of fire extinguishing time and cooling efficiency.However,in terms of thermal radiation isolation,the high-pressure fine water mist system is more effective.The occlusion ratio of obstacles significantly affects the fire extinguishing efficiencies of both the high-pressure fine water mist system and CAFS,with a negative correlation between fire extinguishing efficiency and occlusion ratio of obstacles.Notably,the influence of occlusion ratio of obstacles on the fire extinguishing efficiency of CAFS system is particularly significant.The research results can provide reference for the optimization design of indoor substation fire protection system and ensure the normal operation of substations.
