摘要： 为探讨更为有效的油浸式变压器防护方式，以户外220 kV油浸式变压器为研究对象，研制了油浸式变压器实体灭火试验平台，通过开展高压细水雾、水喷雾与泡沫喷雾灭火试验，以此分析多种灭火方式在燃烧试验中单一作用与协同作用下的不同灭火效果。通过实体火灾燃烧试验，验证多种灭火方式在户外油浸式变压器中的有效性。试验结果表明：与水喷雾灭火系统相比，高压细水雾灭火系统在灭火用水量与烟气洗消方面存在优势；协同作用下的灭火系统，与单一灭火系统相比，在灭火效率上效果更明显。

Abstract: To explore more effective way of oil-immersed transformer protection, an outdoor 220 kV oil-immersed transformer is used as the research object, and an oil-immersed transformer physical fire test platform is developed to analyze the different fire extinguishing effects of various fire extinguishing methods in the combustion test by conducting high pressure fine water mist, water spray and foam spray fire extinguishing tests as a single action and synergistic action. The effectiveness of multiple fire extinguishing methods in outdoor oil-immersed transformers was verified through physical fire combustion tests. The test results show that the high-pressure fine water mist fire extinguishing system has advantages over the water spray fire extinguishing system in terms of water consumption and smoke decontamination; and the synergistic fire extinguishing system has obvious effects on the fire extinguishing efficiency compared with the single fire extinguishing system.

Key words: 220 kV outdoor oil-immersed transformer, fire fighting system, full-scale experiment
