摘要: 为探究当前国网系统内大型变压器灭火系统的有效性,搭建大型变压器消防灭火真型试验平台,火灾模型选用220 kV实体变压器,并分别采用压缩空气泡沫灭火系统和泡沫喷雾灭火系统开展灭火试验研究,对比分析两种灭火系统的灭火有效性。试验结果表明:在相同的火灾燃烧条件下,压缩空气泡沫灭火系统在0.7 MPa的工作压力及6 L/(min·m2)的泡沫混合液供给强度下,34 s扑灭变压器火灾;泡沫喷雾灭火系统在0.7 MPa的工作压力及8 L/(min·m2)的泡沫混合液供给强度下,39 s仅剩高位油盘残火;试验证明压缩空气泡沫灭火系统的灭火性能优于泡沫喷雾灭火系统。本次试验为大型变压器的消防设计提供技术参数和试验依据。

Abstract: To study the effectiveness of large transformer extinguishing system in State Grid sites, the large transformer fire extinguishing test platform has been built and 220 kV transformer fire model was employed to compare the fire extinguishment capability of compressed air foam extinguishing system and foam spray system. The test results showed that: under the same fire conditions, the compressed air foam extinguishing system of 6 L/(min·m2) foam application rate at 0.7 MPa can put out fire within 34 s. The foam spray system of 8 L/(min·m2) foam application rate at 0.7 MPa could put out fire in 39 s, only remaining high level oil pan slash fire. The tests showed that the fire extinguishment capability of compressed air foam extinguishing system was better than that of foam spray system. The experiment provided technical parameters and experimental basis for fire protection design of large transformer.

Key words: large transformer, transformer fire, compressed air foam extinguishing system, foam spray system, effectiveness of fire suppression
