摘要: 从变压器溢油火灾的产生原因出发,开展压缩空气泡沫灭变压器全液面溢油火的缩尺实验,对压缩空气泡沫喷淋系统和泡沫枪两种灭火方式进行了研究,考察了压缩空气泡沫扑灭此类火灾的优势以及火灾变化规律。研究表明,成膜型压缩空气泡沫扑灭变压器全液面溢油火是有效的,能够在高温油面形成稳定覆盖层,防止沸溢喷溅;冷却降温是灭火的关键因素,将油温降低到燃点以下,可扑灭溢油火灾并防止发生复燃。

Abstract: Based on causes of oil spill fires in transformers,a series of small - scale experiments on compressed air foam extinguishing whole - surface spill fires in transformers were studied.With compressed air foam sprinkler system and foam gun,two types of fire extinguishing methods were applied.The advantage and variation rule of extinguishing whole - surface oil spill fires in transformers with compressed air foam were evaluated. The study showed that the film - formed compressed air foam was effective in extinguishing whole - surface oil spill fires in transformers.It could form a stable coating on the high - temperature oil surface to prevent boiling and splashing.Cooling was the key factor for extinguishing fire.It could extinguish whole - surface oil spill fires in transformers and prevent re - ignition by cooling the oil temperature below the ignition point.

Key words: oil - immersed transformer;whole - surface, compressed air foam;spill fire
