城市电力电缆隧道的通风设计

Ventilation Design of Urban Power Cable Tunnel

介绍了城市电缆隧道与工业厂区及变电站电缆隧道的区别,及城市电缆隧道通风必要性,进而确定城市电缆隧道的通风方式。通过某工程通风量的两种不同计算方法验证了防火分区、通风分区的划分,通风温度等参数确定的合理性,并比较了两种计算结果差异产生的原因。

This paper introduces the difference among urban power cable tunnel,industrial cable tunnel and substation cable tunnel.It also presents the necessity of ventilation for urban cable tunnel and the type of ventilation for urban cable tunnel.Two different calculation methods were used to calculate ventilating rate of one engineering project to define the fire compartment and ventilated compartment,to justify the ventilation temperature parameters,and cause of different calculation results for the two methods were compared.
