摘　　要：从城市轨道交通车站剩余电流式电气火灾监控探测器的工作原理入手,分析了剩余电流式电气火灾监控探测器产生误报的共性原因及个性原因:共性原因主要为末端设备切换装置的选型有误和末端接地系统的选择有误,个性原因主要为电缆施工引发的系统误报。针对产生误报的原因提出了减少剩余电流式电气火灾监控探测器误报的建议。Starting with the fundamentals of residual current electrical fire monitoring detectors,the common reasons and individual reasons of false alarm of the residual current electrical fire monitoring detectors are analyzed.The common reasons are mainly the problems of terminal equipment switch device type selection and terminal earthing system selection,and the individual reasons are mainly the system false alarming caused by cable construction.Targeting the reasons of false alarming,reasonable measures to reduce the false alarm of residual current electrical fire monitoring detector are proposed.
