摘　　要：采用FDS数值模拟软件模拟分析典型高温高湿条件下,电缆火灾对舱室关键设备安全性的影响结果表明,火源功率及环境温度对于关键设备表面温度和表面热流的影响较大,当火源功率超过6 MW或环境温度超过50℃,邻近火源设备存在失效风险,某特殊材料温度接近失效温度,存在失效的可能性,建议控制火灾可燃物的数量和舱室初始环境温度,环境湿度及是否通风对火场温度及热流分布的影响不大。The FDS simulation software was used to study the influence of cable fire on cabin in the typical location under special environmental conditions.The numerical results showed that the fire power and ambient temperature have great influence on the surface temperature and heat flow of key equipment.When the power of the fire source exceeds 6 MW or the ambient temperature exceeds 50℃,there is a failure risk of the adjacent equipment,so the amount of combustible and the initial ambient temperature of the cabin should be controlled.The ambient humidity and ventilation have little influence on the temperature and heat flow distribution of the fire field.
