摘要
通过图文形式,详细介绍国家建筑标准设计14X505-1《〈火灾自动报警系统设计规范〉图示》中关于总线短路隔离器的相关设计内容。解析总线短路隔离器设置的意义,每只总线短路隔离器保护的消防设备不应超过32点的含义,总线短路隔离器的接线,及其在穿越防火分区时的设置等具体问题,并给出工程示例。
The paper introduces the design-related contents of bus short circuit isolator in detail in national building standard disign 14X505-1 Graphical Representation of “Code for Design of Automatic Fire Alarm System”. Concrete issues, such as the significance of setting the isolators, the meaning of the number of fire equipment protected by each isolator not exceeding 32, wiring of the isolator and setting for the bus crossing the fire compartment, are analyzed with project examples.
