剩余电流式电气火灾监控探测器的设置

摘要

根据民用建筑中通用用电设备正常泄漏电流的情况，结合GB 50116-2013《火灾自动报警系统设计规范》对剩余电流式电气火灾监控探测器设置的要求，分析不同类型负荷、供配电方式对探测器设置的影响；提出可以根据塑壳式断路器额定电流来简便地确定探测器的位置；并对消防线路中探测器的设置展开讨论。%According to normal leakage current of general electrical equipment in civil buildings and in combination with the requirements for setting of leakage current detectors for electric fire prevention in Code for Design of Automatic Fire Alarm System (GB 50116-2013), the paper analyses the influence of different loads and power supply and distribution modes, proposes a simple method to set detector with the rated current of molded case circuit breaker and discusses the setting of detector in fire line.
