摘要:
针对油浸变压器火灾的高危险性，搭建了1∶1室外变压器全尺寸火灾实验平台，开展了油枕喷射火及底部油池火实体实验，并探究了高压细水雾灭火系统的效能与作用机理。通过高速摄影、热电偶阵列等设备分析火灾发展规律、温度变化曲线及高压细水雾灭火机理。结果表明，细水雾液滴在高温环境中引发了燃烧区气体体积骤增，出现显著的“火焰强化”现象；细水雾通过双重机制实现快速灭火，即与高温油接触时快速汽化以中断链式反应，同时通过液滴覆盖油面形成全淹没环境隔绝氧气；在环境风速≤3 m/s条件下，系统对喷射火与油池火均表现出高效灭火性能，灭火时间小于137 s。
Abstract:
To address the high risk of oil-immersed transformer fires, a 1∶1 full-scale outdoor experimental platform was constructed. Experiments on fire scenarios including oil conservator spray fires and bottom pool fires were conducted, with a focus on evaluating the effectiveness and mechanism of the high-pressure water mist fire extinguishing system. High-speed photography and thermocouple arrays were employed to analyze fire development patterns, temperature variation curves, and the extinguishing mechanism of the high-pressure water mist. The results showed that water mist droplets caused a sharp increase in gas volume within the combustion zone under high temperatures, leading to a significant “fire enhancement” phenomenon. The water mist achieved rapid extinguishment through a dual mechanism: rapid vaporization upon contacted with high-temperature oil to interrupt chain reactions, and coveraged of the oil surface with droplets to create a total-flooding environment that cuted off oxygen supply. Under environmental wind speeds no more than 3 m/s, the system demonstrated high-efficiency fire extinguishing performance for both spray fires and pool fires, with extinguishment times of less than 137 seconds.
