　  作用：

    電(dian)流(liu)(liu)(liu)繼(ji)(ji)電(dian)器(qi)(qi)主(zhu)(zhu)要是(shi)反映電(dian)流(liu)(liu)(liu)變化，在電(dian)器(qi)(qi)設備的(de)電(dian)氣回(hui)路中可以起到(dao)電(dian)流(liu)(liu)(liu)保(bao)護(hu)和控制(zhi)(zhi)的(de)作用(yong)(yong)。電(dian)流(liu)(liu)(liu)繼(ji)(ji)電(dian)器(qi)(qi)是(shi)接在主(zhu)(zhu)回(hui)路當(dang)中，當(dang)回(hui)路中的(de)電(dian)流(liu)(liu)(liu)達(da)到(dao)電(dian)流(liu)(liu)(liu)繼(ji)(ji)電(dian)器(qi)(qi)規定范圍外的(de)電(dian)流(liu)(liu)(liu)值時(shi)這(zhe)時(shi)就會跳開(kai)主(zhu)(zhu)回(hui)路同時(shi)發生(sheng)相關信號。電(dian)流(liu)(liu)(liu)繼(ji)(ji)電(dian)器(qi)(qi)通常(chang)用(yong)(yong)于自動(dong)控制(zhi)(zhi)電(dian)器(qi)(qi)的(de)電(dian)路中，進行通過(guo)較小的(de)電(dian)流(liu)(liu)(liu)去控制(zhi)(zhi)較大(da)電(dian)流(liu)(liu)(liu)的(de)自動(dong) 開(kai)關 ，進行轉換電(dian)路起到(dao)安全(quan)保(bao)護(hu)的(de)作用(yong)(yong)。

　　電(dian)(dian)流繼(ji)電(dian)(dian)器在使用(yong)時，需要(yao)把外部(bu)的(de)殼取掉(diao)，拔出機器然后(hou)檢查是否在運輸過程中(zhong)有無產(chan)生損壞，比如電(dian)(dian)流繼(ji)電(dian)(dian)器的(de)磁板與動(dong)片相碰撞摩擦(ca)了。這時我們要(yao)將電(dian)(dian)流繼(ji)電(dian)(dian)器的(de)指針調動(dong)到(dao)第一個整點上，用(yong)手將可動(dong)系統朝向磁板轉動(dong)再放(fang)開，可動(dong)系統應當轉回到(dao)最初原來(lai)的(de)位置直到(dao)停(ting)止檔(dang)位，進行必要(yao)的(de)調整核對就可以(yi)了。

　　電(dian)流(liu)繼電(dian)器(qi)通常情況下是需要一定程度(du)的(de)電(dian)流(liu)強度(du)，剛達到一定的(de)電(dian)流(liu)強度(du)，電(dian)流(liu)繼電(dian)器(qi)才開(kai)始進(jin)行(xing)工作。

　　常用的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器有過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器和欠(qian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器。過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器是當電(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)路處在短路或是當被保(bao)護(hu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)路超過(guo)了(le)規定(ding)范(fan)(fan)圍(wei)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)額(e)定(ding)值時(shi)(shi)，過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器開(kai)始(shi)進(jin)(jin)行(xing)工(gong)作(zuo)，控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路流(liu)(liu)失(shi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，從而(er)控(kong)制(zhi) 接觸器 進(jin)(jin)行(xing)分斷轉換電(dian)(dian)(dian)(dian)(dian)(dian)路，對電(dian)(dian)(dian)(dian)(dian)(dian)路起到(dao)過(guo)流(liu)(liu)保(bao)護(hu)效果。欠(qian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)工(gong)作(zuo)原理是剛電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)低于規定(ding)范(fan)(fan)圍(wei)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)額(e)定(ding)值時(shi)(shi)，欠(qian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器便開(kai)始(shi)進(jin)(jin)行(xing)工(gong)作(zuo)將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)路進(jin)(jin)行(xing)分斷。

　　電(dian)(dian)(dian)(dian)流繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)動片與磁極之間是(shi)有縫(feng)隙的(de)(de)(de)(de)呢，我們要(yao)保證電(dian)(dian)(dian)(dian)流繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)無論處(chu)在(zai)任何一種工作狀態下，電(dian)(dian)(dian)(dian)流繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)動片和磁極都(dou)不能夠進(jin)行(xing)(xing)相碰(peng)處(chu)、電(dian)(dian)(dian)(dian)流繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)在(zai)使用時不應潤滑電(dian)(dian)(dian)(dian)流繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)軸承(cheng)、在(zai)清潔電(dian)(dian)(dian)(dian)流繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)觸(chu)點(dian)時適合使用比較(jiao)(jiao)鋒(feng)刃的(de)(de)(de)(de)刀片或(huo)是(shi)細磨石，之后再去干(gan)凈(jing)柔軟的(de)(de)(de)(de)布進(jin)行(xing)(xing)擦拭，避免能手指(zhi)接觸(chu)到電(dian)(dian)(dian)(dian)流繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)觸(chu)點(dian)，切記不要(yao)用砂紙或(huo)是(shi)其他(ta)比較(jiao)(jiao)糙的(de)(de)(de)(de)東西來清潔電(dian)(dian)(dian)(dian)流繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)觸(chu)點(dian)。
