Abstract：With help of practical tests and the applicable products and standards,this paper analyzes the residual currents of elevator loads monitored in their start,run,end and stop states to figure out the root causes of residual current false alarms. It also gives an overall solution and the software and hardware realization methods for the root cause to reduce the false alarm rate of residual current type electrical fire monitoring detectors significantly.

Key words：residual current type electrical fire monitoring detector;false alarm;elevator;frequency converter;electrical fire;power quality;filtering;algorithm

摘　要：通过实际试验，结合产品和标准分析电梯类负载在启动、运行、结束、停止等状态下监控的剩余电流，分析造成剩余电流误报警的根本原因。并就具体原因给出整体解决方案及软件、硬件的具体实现途径及方法，可大大降低剩余电流式电气火灾监控探测器的误报警率。
