漏电报警器是一个安全装置，可以通过剩余电流（漏电流）互感器（即互感线圈）采集需监测线路的漏电值，并对漏电值进行分析、比较，在达到一定预设值时发出声光报警。
Leakage alarm is a safety device. It can collect the leakage value of the line to be monitored through the residual current (leakage current) transformer (mutual inductance coil), analyze and compare the leakage value, and give sound and light alarm when it reaches a certain preset value.
随着电气火灾事故的逐年增加，新《消防法》、《高层民用建筑设计防火规范》、《火灾自动报警系统设计规范》等法规都提出了针对建筑物内防火技术的更高要求，漏电报警器已不能满足人们的需求，代之而来的是精度更高，可靠性更强，可实时显示漏电值并通过通讯总线实现远程监控的一整套系统，即“小武松电气防火监控系统”
With the increase of electric fire accidents year by year, the new Fire Protection Law, Fire Protection Code for High-rise Civil Architectural Design and Design Code for Fire Automatic Alarm System have put www.yeyadabaoji.com.cnwww.hfguoyu.cnwww.dispLay0755.com.cnwww.coron.com.cnforward higher ge.75ix.comdugebang.75ix.comrequirements for fire prevention technology in buildings. Leakage alarms can no longer meet people's needs. Instead, they have higher accuracy, stronger reliability and can display the leakage value in real time and connect them. A complete set of system for remote monitoring through communication bus, namely "Xiaowusong Electrical Fire Prevention and Control System"
