金属管厚度对明敷消防供配电线路保护效果的模拟研究

Simulation of Protective Effects of Metal Tube Wall Thicknesses on Unconcealed Electrical Wires for Firefighting

为研究不同厚度的金属管对明敷消防供配电线路保护效果的影响有何不同,利用ANSYS软件建立电线穿金属管涂敷防火涂料模型,通过计算得出模型温度分布以及模型内部任意节点温度随时间变化规律,同时对不同消防设备明敷配电线路穿金属管的厚度提供了数值参考。

With the use of ANSYS, a model has been built to study the different protective effect of mental tube wall with different thicknesses on the unconcealed electrical wire for firefighting. The study results show that the tempera- ture distribution and the temperature of any location inside the model change with time. This paper provides the nu- merical value reference of mental tube wall thickness for different firefighting equipment.
