提起漏電開關，很多人(ren)并(bing)不會感到(dao)陌生，但(dan)是若真要讓你對它的細(xi)節(jie)說出(chu)個所以然來，并(bing)準(zhun)確(que)地回答出(chu)漏(lou)電開(kai)(kai)關(guan)是什么，還是讓不少(shao)人(ren)一(yi)頭霧水。想了解更多的知識嗎？下面就(jiu)請大家(jia)跟隨一(yi)起裝修網小編的腳(jiao)步(bu)一(yi)起去看看漏(lou)電開(kai)(kai)關(guan)是什么，漏(lou)電開(kai)(kai)關(guan)原理吧。

漏電開關是什么

　　漏(lou)電(dian)(dian)(dian)開(kai)關，主(zhu)(zhu)要用于(yu)防止漏(lou)電(dian)(dian)(dian)事故的(de)發生，其開(kai)關的(de)動(dong)作原理是：在(zai)(zai)一個(ge)(ge)鐵芯上(shang)有兩(liang)(liang)個(ge)(ge)繞(rao)組(zu)(zu)(zu)，主(zhu)(zhu)繞(rao)組(zu)(zu)(zu)和(he)(he)(he)副(fu)(fu)(fu)繞(rao)組(zu)(zu)(zu)。主(zhu)(zhu)繞(rao)組(zu)(zu)(zu)也有兩(liang)(liang)個(ge)(ge)繞(rao)組(zu)(zu)(zu)：分別為輸(shu)入電(dian)(dian)(dian)流繞(rao)組(zu)(zu)(zu)和(he)(he)(he)輸(shu)出電(dian)(dian)(dian)流繞(rao)組(zu)(zu)(zu)。無漏(lou)電(dian)(dian)(dian)時，輸(shu)入電(dian)(dian)(dian)流和(he)(he)(he)輸(shu)出電(dian)(dian)(dian)流相等(deng)，在(zai)(zai)鐵芯上(shang)二(er)磁通的(de)矢量和(he)(he)(he)為零(ling)，就不會(hui)在(zai)(zai)副(fu)(fu)(fu)繞(rao)組(zu)(zu)(zu)上(shang)感應出電(dian)(dian)(dian)勢(shi)，否則(ze)副(fu)(fu)(fu)繞(rao)組(zu)(zu)(zu)上(shang)就會(hui)感應電(dian)(dian)(dian)壓形成，經放大(da)器推動(dong)執行機(ji)構，使(shi)開(kai)關跳閘。

　　漏電(dian)(dian)(dian)開(kai)(kai)關的(de)接法。相(xiang)(xiang)(xiang)漏電(dian)(dian)(dian)開(kai)(kai)關是(shi)(shi)三相(xiang)(xiang)(xiang)四(si)線制是(shi)(shi)現今普遍采用的(de)，三根火(huo)線（紅、綠、黃），一(yi)根零線（藍），三根火(huo)線之間(jian)的(de)電(dian)(dian)(dian)壓是(shi)(shi)380伏(fu)，每根火(huo)線對(dui)零線間(jian)的(de)電(dian)(dian)(dian)壓是(shi)(shi)220伏(fu)。單相(xiang)(xiang)(xiang)的(de)漏電(dian)(dian)(dian)開(kai)(kai)關一(yi)般接線處，寫著左零右火(huo)，按照(zhao)接就好(hao)了(le)。不(bu)管(guan)三相(xiang)(xiang)(xiang)還是(shi)(shi)單相(xiang)(xiang)(xiang)的(de)漏電(dian)(dian)(dian)開(kai)(kai)關都是(shi)(shi)：上(shang)面進線，下面出線。

漏電開關原理

　　漏電(dian)(dian)(dian)保護開關(guan)的動作原理是：在一個(ge)(ge)(ge)鐵芯(xin)上(shang)有兩個(ge)(ge)(ge)組(zu)：一個(ge)(ge)(ge)輸入電(dian)(dian)(dian)流繞(rao)(rao)(rao)組(zu)和(he)一個(ge)(ge)(ge)輸出電(dian)(dian)(dian)流繞(rao)(rao)(rao)組(zu)，當無漏電(dian)(dian)(dian)時，輸入電(dian)(dian)(dian)流和(he)輸出電(dian)(dian)(dian)流相等，在鐵芯(xin)上(shang)二磁通的矢量(liang)和(he)為零，就不會在第三個(ge)(ge)(ge)繞(rao)(rao)(rao)組(zu)上(shang)感應出電(dian)(dian)(dian)勢，否則第三繞(rao)(rao)(rao)組(zu)上(shang)就會感應電(dian)(dian)(dian)壓形成，經放大(da)去(qu)推動執(zhi)行(xing)機(ji)構，使開關(guan)跳閘。

　　正常工作(zuo)時電(dian)(dian)(dian)路中除了工作(zuo)電(dian)(dian)(dian)流(liu)外沒有漏電(dian)(dian)(dian)流(liu)通(tong)(tong)過(guo)漏電(dian)(dian)(dian)保護(hu)(hu)器(qi)，此時流(liu)過(guo)零序互(hu)(hu)(hu)感器(qi)(檢測互(hu)(hu)(hu)感器(qi))的(de)電(dian)(dian)(dian)流(liu)大小相(xiang)等(deng)，方向相(xiang)反(fan)，總和為零，互(hu)(hu)(hu)感器(qi)鐵(tie)芯中感應磁(ci)通(tong)(tong)也等(deng)于零，二(er)次繞組無(wu)輸出(chu)(chu)，自動開(kai)關保持在接(jie)通(tong)(tong)狀態，漏電(dian)(dian)(dian)保護(hu)(hu)器(qi)處于正常運行。當(dang)被保護(hu)(hu)電(dian)(dian)(dian)器(qi)與線路發生漏電(dian)(dian)(dian)或有人觸電(dian)(dian)(dian)時，就有一個(ge)接(jie)地故(gu)障電(dian)(dian)(dian)流(liu)，使流(liu)過(guo)檢測互(hu)(hu)(hu)感器(qi)內(nei)電(dian)(dian)(dian)流(liu)量和不為零，互(hu)(hu)(hu)感器(qi)鐵(tie)芯中感應出(chu)(chu)現磁(ci)通(tong)(tong)，其二(er)次繞組有感應電(dian)(dian)(dian)流(liu)產(chan)生，經放(fang)大后輸出(chu)(chu)，使漏電(dian)(dian)(dian)脫扣器(qi)動作(zuo)推動自動開(kai)關跳閘達(da)到漏電(dian)(dian)(dian)保護(hu)(hu)的(de)目的(de)。
