摘　　要：目前的剩余电流式电气火灾监控系统均采用固定阈值报警,在实际使用中存在误报警和漏报警问题。本文分析了该监控系统产生误报警和漏报警的原因以及固定阈值报警的局限性,并根据配电系统正常剩余电流随负荷电流变化的实测数据,提出了一种新型剩余电流式电气火灾监控系统的智能算法,该算法能够动态自动调整报警阈值,从而实现准确报警。Currently,fixed alarm threshold is introduced in the residual current monitoring system for electric fire prevention, which results in false alarm and irresponsiveness in practice. In this paper, the reasons of false alarm and irresponsiveness and the limitation of the fixed alarm threshold were analyzed. The new type of intelligent algorithm was introduced by analyzing the residual current and load current data, which was able to adjust alarm threshold automatically and achieve alarm warning accurately.
