一、智(zhi)慧用电安全(quan)管理(li)系统(tong)简介

　　力安(an)科技智慧用电(dian)(dian)安(an)全管理系统是一套(tao)专(zhuan)业(ye)防(fang)范电(dian)(dian)气(qi)火(huo)灾隐患的系统，通过接入物(wu)联网、大数据进(jin)行(xing)分析处(chu)理，实现(xian)电(dian)(dian)气(qi)数据从(cong)现(xian)场传(chuan)输(shu)到云(yun)平台(tai)，再从(cong)云(yun)平台(tai)发(fa)送(song)给终端(duan)设(she)备，用户可以通过手机、电(dian)(dian)脑等实现(xian)对过线电(dian)(dian)流(liu)、线缆温度、漏(lou)电(dian)(dian)等异常数据的实时(shi)监控，预报(bao)警功能(neng)帮助(zhu)用户实现(xian)对电(dian)(dian)气(qi)火(huo)灾的及(ji)时(shi)诊(zhen)断处(chu)理，防(fang)止电(dian)(dian)气(qi)火(huo)灾的发(fa)生。

　　二、智(zhi)慧(hui)用电(dian)组成部件(jian)的介绍及原理

　　常见的漏(lou)电、短路、过载、接(jie)触(chu)不良是(shi)电气(qi)火(huo)灾的主要(yao)成因。智慧(hui)用(yong)电安全管理(li)系统，可以对电气(qi)设(she)备的日常运行(xing)进行(xing)24小(xiao)时(shi)实时(shi)监管，及(ji)时(shi)发(fa)现这些隐患(huan)(huan)，并通知相关(guan)人员及(ji)时(shi)有效消除电气(qi)设(she)备的这些上(shang)述(shu)隐患(huan)(huan)。

1、漏电，是电气(qi)火灾的(de)主(zhu)要(yao)成因。

　　剩余电(dian)流式(shi)电(dian)气(qi)火灾监控探测器(qi)，可以监测到电(dian)气(qi)回路中漏电(dian)电(dian)流的大小，超过系统预设数值，会发(fa)出报警(jing)信(xin)号。

　　在电(dian)(dian)气(qi)回路(lu)中，流(liu)经相(xiang)(xiang)(xiang)线(xian)的电(dian)(dian)流(liu)，终都会经零(ling)线(xian)回去。也就是说：A相(xiang)(xiang)(xiang)电(dian)(dian)流(liu)值(zhi)+B相(xiang)(xiang)(xiang)电(dian)(dian)流(liu)值(zhi)+C相(xiang)(xiang)(xiang)电(dian)(dian)流(liu)值(zhi)=N零(ling)线(xian)的电(dian)(dian)流(liu)。

　　注意：剩(sheng)(sheng)余(yu)电(dian)(dian)流(liu)式探测(ce)器的剩(sheng)(sheng)余(yu)电(dian)(dian)流(liu)传感器（圆孔(kong)型或(huo)长方(fang)(fang)形(xing)）在安装时，必(bi)须把3根(gen)相线和1根(gen)零线都穿入，且方(fang)(fang)向要*，如(ru)下(xia)图2所(suo)示。

　　原理：相线(xian)(xian)不漏(lou)电(dian)(dian)的(de)情(qing)况，穿过剩(sheng)余(yu)电(dian)(dian)流传(chuan)感器的(de)相线(xian)(xian)电(dian)(dian)流与(yu)零线(xian)(xian)电(dian)(dian)流，大小相等，方向相反(fan)，相互抵消，剩(sheng)余(yu)电(dian)(dian)流值为0.当相线(xian)(xian)漏(lou)电(dian)(dian)的(de)时候，回流到(dao)零线(xian)(xian)的(de)电(dian)(dian)流会变小，剩(sheng)余(yu)电(dian)(dian)流值就是相线(xian)(xian)中漏(lou)电(dian)(dian)电(dian)(dian)流的(de)值。

　　如下图所示

2、短路(lu)和接(jie)触不良，也是(shi)电气发生火(huo)灾(zai)的主要(yao)因素(su)。

　　线路短(duan)路或者接触不良，常伴有电(dian)弧（电(dian)火花）产生(sheng)，应该采(cai)用故障(zhang)电(dian)弧探测器。

　　3、当线路(lu)过载或者短路(lu)时，还伴随另外(wai)一个现(xian)象：发热(re)。

　　可以(yi)采(cai)用(yong)测温(wen)(wen)式(shi)监控探测器(qi)，对(dui)线路(lu)温(wen)(wen)度(du)进(jin)行测量。

　　三、智慧用(yong)电(dian)安(an)全(quan)管理系统的应用(yong)与设置

　　剩(sheng)余电流式智慧用电安全探测器(qi)，应遵(zun)循基本的设置(zhi)要求：

　　1、剩余电流(liu)(liu)式智(zhi)慧(hui)用电安(an)全探(tan)测器，应(ying)以(yi)设置(zhi)在(zai)低压配电系统首端为原则，宜(yi)设置(zhi)在(zai)*级配电柜的出线(xian)端。如(ru)果供(gong)电线(xian)路泄漏电流(liu)(liu)大于500mA，宜(yi)在(zai)下(xia)一级配电柜设置(zhi)。

　　2、剩余电(dian)流式智慧(hui)用电(dian)安(an)全(quan)探测器，在(zai)配电(dian)柜安(an)装时(shi)，相线和零线必须同(tong)时(shi)穿(chuan)(chuan)入，且保持同(tong)一方向穿(chuan)(chuan)入，地线不得穿(chuan)(chuan)入。

　　3、剩余电(dian)流式智慧用电(dian)安全探(tan)测(ce)器，其电(dian)源信(xin)号就(jiu)地取电(dian)，接(jie)在被保(bao)护线路的前(qian)端，禁止(zhi)从(cong)保(bao)护器下端接(jie)线。

　　智慧(hui)用电是提升(sheng)公共/安全(quan)管(guan)理的(de)有效手(shou)段(duan)，是落实企业主体责任和规避风(feng)险的(de)需(xu)要(yao)，各(ge)部门要(yao)按时(shi)间按要(yao)求在(zai)全(quan)县(xian)各(ge)个乡镇、企业进(jin)行推(tui)广；要(yao)在(zai)思想上升(sheng)级，高度重视(shi)智慧(hui)用电是社会发(fa)展的(de)大势(shi)所趋；要(yao)明确目(mu)标，对推(tui)广进(jin)度进(jin)行督(du)促(cu)、检(jian)查和考核(he)，从(cong)而(er)达到在(zai)全(quan)县(xian)推(tui)广使用智慧(hui)用电的(de)目(mu)的(de)。
