摘要： 通过缩尺灭火试验，研究压缩空气泡沫对变压器升高座溢油火灾的灭火有效性，分析提出适宜的灭火应用方式及应用参数。结果表明，压缩空气泡沫可有效扑灭变压器升高座溢油火灾，具备良好的灭火和抗复燃能力；在泡沫溶液供给强度为11.4 L/（min · m 2 ）条件下，灭火时间为 3.9 min，连续供泡 10 min，将油温降至变压器油燃点以下，且灭火后不发生复燃；提高泡沫溶液供给强度可以提高灭火与降温速度。实际工程中建议采用压缩空气泡沫喷淋系统和稳定性高的压缩空气泡沫，且释放装置与管网应采取抗爆炸冲击措施。

Abstract: The fire suppression effectiveness of compressed air foam for bushing turret spill fire of transformer was studied through reduced - scale fire extinguishing experiments. The suitable fire extinguishing application method and application parameters were analyzed and proposed. The results showed that compressed air foam could effectively extinguish the bushing turret spill fire of transformer, and had a good ability of fire extinguishing and antireigniting.Under the condition that the foam solution supply intensity was 11.4 L/(min · m 2 ), the fire extinguishing time is 3.9 min. By supplying foam for 10 min, the transformer oil temperature could be reduced to below the ignition point, and re - ignition would not occur.Increasing the supply strength of foam solution can increase the speed of fire extinguishing and cooling. In actual engineering, it’s recommended to use a compressed air foam sprinkler system and a highly stable compressed air foam. The compressed air foam release device and the pipe network should adopt anti - explosion measures.

Key words: oil - immersed transformer, bushing turret, spill fire; compressed air foam, sprinkler fire extinguishing system
