消防用电设备供电系统的再思考

Rethinking of Power Supply System for Fire Power Equipment

消防用电设备供电的可靠性和供电要求在现行的建筑设计防火规范中有明确的要求,包括从总配电箱或变电所至末端消防设备的配电系统要求,但是对于其上一级电源系统的要求是否存在不完善之处,值得思考。结合具体工程案例,对消防负荷供电系统提出了一些思考,希望相关规范编制单位能够考虑工程实际进一步明确做法。

The supply reliability and supply requirements of fire fighting apparatus are clearly specified in the current code for fire prevention in building design,including the distribution system requirements from the main distribution box or substation to the terminal fire fighting equipment.However,it is considering whether there is any imperfection in the requirements of its superior power supply system.Combining with specific cases,the new ideas were put forward for the power supply system of fire-fighting load.It is hoped that relevant specification compiling units can take into account the engineering practice to further clarify the practice.
