摘要: 为深入了解变压器油的燃爆危险性,采用可燃气体/蒸气爆炸特性测试系统和可燃液体雾滴燃爆测试系统,对 45#新鲜变压器油和废旧变压器油的油气/雾燃爆危险性进行对比研究。结果表明:随着温度从 115 ℃上升到 150 ℃,油气的爆炸下限降低,燃爆危险性变大;温度一定时,随着喷射压力从 0.8 MPa 上升到 2.4 MPa,油雾粒径变小,发生燃烧爆炸的持续时间变长,燃爆危险性变大;新鲜变压器油的燃爆危险性更大。

关键词: 变压器油, 爆炸下限, 油雾粒径, 喷射压力

Abstract: In order to understand the deflagration risk of transformer oil indepth,the deflagration characteristic of 45# fresh and waste transformer oil was studied by combustible gas/vapor explosion test system and flammable liquid droplet deflagration test system. The results showed that as the temperature rises from 115 ℃ to 150 ℃ , the lower explosion limit of oil gas decrease, and the risk of deflagration increases; When the temperature is constant, as the injection pressure rises from 0.8 MPa to 2.4 MPa,the particle size of oil droplet decreases, the duration of deflagration increases, and the risk of deflagrationupgrades;The deflagration risk of fresh transformer oil is greater.

Key words: transformer oil, lower explosion limit, oil mist particle size, injection pressure
