油浸式变压器短路故障后阴燃风险的防范

Prevention of Smoldering Risk after Short Circuit Fault of Oil-immersed Transformers

近年来对变压器短路后的明火火灾防范警惕性较高,但对大型变压器短路故障后阴燃火灾的危害认识不足。分析了一起500 kV变压器短路故障后阴燃现象及现场控制措施,为变压器消防设施设计和灾后抢修提供了一定经验。

In recent years,there has been a high level of vigilance against open fires after transformer short-circuits,but there is insufficient understanding of the hazards of smoldering fires after large-scale transformer short-circuit faults.The smoldering phenomenon and on-site control measures was analyzed after a 500kV transformer short-circuit fault,and some experience for the design of transformer fire protection facilities and emergency repair were provided.
