摘要:
为了研究不同火源条件下变压器火灾动力学过程，利用全尺寸变压器火灾试验，验证了隐蔽、立体、多尺度的变压器火灾数值模拟的有效性，模拟5，10，15，18 MW火源功率下变压器室内火灾烟气蔓延、温度分布变化。研究结果表明：火源功率对烟气蔓延速度和温度分布影响较大，当火源功率在18 MW以内时，变压器油燃烧时间在30 s内，产生的热均不会使变压器室内壁面和顶棚处的烟气温度超过300 ℃，没有达到混凝土的耐火极限。
Abstract:
The transformer oil fire is a highintensity turbulent combustion phenomenon, and its gestation, generation and development include the physical and chemical effects such as turbulent flow, phase change, heat and mass transfer, and complex chemical reactions. In order to study the dynamic process of transformer fire under different conditions of fire source, the fullscale tests of transformer fire was used to verify the validity of concealed, threedimensional and multiscale numerical simulation of transformer fire, and the smoke spreading and temperature distribution in the transformer room under the fire source power of 5, 10, 15, 18 MW were simulated. The results showed that the fire source power had great influence on the smoke spreading speed and temperature distribution. When the fire source is less than 18MW and the burning time of the transformer oil is within 30 s, the heat generated will not make the flue gas temperature at the wall and ceiling in the transformer room exceed 300 ℃, which does not reach the fire resistance limit of concrete.
