摘　　要：消防负荷计算是选择应急电源容量的依据,博物馆建筑通常有很多高大空间,防排烟量非常大,防排烟风机在消防负荷中占比较大,计算应急柴油发电机组容量时应深入分析防排烟风机运行情况。当火灾蔓延时消防配电系统也应保证一定的连续性及可靠性。此外,不能忽视大楼中平时兼消防两用风机在火灾时的运行状态对计算结果的影响,在火灾时将非着火区域的平时兼消防两用风机切除。The calculation of fire-fighting load is the basis for selecting the capacity of emergency power supply.There are more high and large space in the museum buildings,so the smoke prevention and exhaust is very large.The firefighting fan has a large proportion in the fire-fighting load,the operation condition of the fire-fighting fan should be analyzed when calculating the emergency diesel generator capacity.When the fire spreads,the fire distribution system should also ensure a certain degree of continuity and reliability.In addition,the influence of the running state of the dual-purpose fan for peacetime and fire fighting in the building on the calculation results can not be ignored,in case of fire,the dual-purpose fan in the non fire area should be cut off.
