摘要
通过开展正交试验,计算分析典型核电站厂房内环境相对湿度、电缆间距和电缆布置方式对电缆火灾特性的影响规律,计算结果表明,由于其内部特殊防火结构,核电站用K3类电缆防火性能优于NC类电缆;布置间距对于电缆燃烧影响较大;电缆放置方式对火灾行为有明显影响。
The influences of ambient relative humidity,cable spacing and cable arrangement upon cable fire characteristics in a typical nuclear power plant awere studied through orthogonal experiments.The results showed that due to its special internal fire protection structure,K3 cables used in nuclear power plants have better fire protection performance than NC cables;the layout spacing has a great impact on cable combustion;and the cable arrangement has a significant impact on fire behavior.
