斷路器常見的故障解決方法有哪些

　　斷路器工(gong)作(zuo)原(yuan)理(li)是(shi)當(dang)短(duan)路(lu)時(shi)
，大(da)電(dian)流(liu)產(chan)生(sheng)的(de)磁(ci)場(chang)克(ke)服(fu)反(fan)力(li)彈(dan)簧(huang)，脫(tuo)扣(kou)器(qi)拉(la)動(dong)操(cao)作(zuo)機(ji)構(gou)動(dong)作(zuo)
，開(kai)關(guan)瞬(shun)時(shi)跳(tiao)閘(zha)。當(dang)過(guo)載(zai)時(shi)，電(dian)流(liu)變(bian)大(da)，發(fa)熱(re)量(liang)加(jia)劇(ju)，雙(shuang)金(jin)屬(shu)片(pian)變(bian)形(xing)到(dao)一(yi)定(ding)程(cheng)度(du)推(tui)動(dong)機(ji)構(gou)動(dong)作(zuo)，電(dian)流(liu)越(yue)大(da)，動(dong)作(zuo)時(shi)間(jian)越(yue)短(duan)。斷(duan)路(lu)器(qi)有(you)電(dian)子(zi)型(xing)的(de)，使(shi)用(yong)互(hu)感(gan)器(qi)采(cai)集(ji)各(ge)相(xiang)電(dian)流(liu)大(da)小(xiao)
，與(yu)設(she)定(ding)值(zhi)比(bi)較(jiao)，當(dang)電(dian)流(liu)異(yi)常(chang)時(shi)微(wei)處(chu)理(li)器(qi)發(fa)出(chu)信(xin)號(hao)
，使(shi)電(dian)子(zi)脫(tuo)扣(kou)器(qi)帶(dai)動(dong)操(cao)作(zuo)機(ji)構(gou)動(dong)作(zuo)。

　　斷duan路lu器qi溫wen升sheng過guo高gao也ye是shi一yi種zhong常chang見jian故gu障zhang。其qi原yuan因yin是shi觸chu頭tou壓ya力li過guo分fen降jiang低di，此ci時shi可ke調tiao整zheng觸chu頭tou壓ya力li或huo更geng換huan彈dan簧huang。該gai故gu障zhang有you時shi也ye可ke能neng是shi由you觸chu頭tou表biao麵mian磨mo損sun嚴yan重zhong或huo者zhe是shi嚴yan重zhong接jie觸chu不bu良liang造zao成cheng的de，此ci時shi應ying更geng換huan新xin的de斷duan路lu器qi。若ruo溫wen升sheng過guo高gao，則ze是shi因yin為wei兩liang個ge導dao電dian零ling件jian的de連lian接jie螺luo釘ding鬆song動dong
，則ze應ying將jiang其qi重zhong新xin擰ning緊jin。

　　當dang發fa生sheng電dian流liu已yi達da整zheng定ding值zhi，而er斷duan路lu器qi不bu能neng正zheng常chang分fen斷duan的de故gu障zhang時shi，應ying檢jian查zha一yi下xia熱re脫tuo扣kou器qi的de雙shuang金jin屬shu片pian是shi否fou損sun壞huai，如ru損sun壞huai則ze應ying更geng換huan。然ran後hou檢jian查zha電dian磁ci脫tuo扣kou器qi的de銜xian鐵tie與yu鐵tie芯xin距ju離li是shi否fou過guo大da或huo線xian圈quan是shi否fou損sun壞huai，進jin而er調tiao整zheng銜xian鐵tie與yu鐵tie芯xin的de距ju離li或huo更geng換huan斷duan路lu器qi。有you時shi還hai會hui出chu現xian啟qi動dong電dian動dong機ji時shi斷duan路lu器qi立li即ji分fen斷duan的de情qing況kuang，這zhe有you可ke能neng是shi因yin為wei過guo電dian流liu脫tuo扣kou器qi瞬shun動dong整zheng定ding值zhi太tai小xiao
，或huo由you於yu運yun行xing中zhong的de振zhen動dong等deng，造zao成cheng整zheng定ding值zhi產chan生sheng了le變bian化hua。可ke以yi調tiao整zheng過guo電dian流liu脫tuo扣kou器qi瞬shun時shi整zheng定ding值zhi至zhi規gui定ding值zhi。如ru為wei某mou些xie零ling件jian損sun壞huai，可ke更geng換huan脫tuo扣kou器qi。

　　當(dang)低(di)壓(ya)斷(duan)路(lu)器(qi)的(de)失(shi)壓(ya)脫(tuo)扣(kou)器(qi)出(chu)現(xian)噪(zao)聲(sheng)時(shi)，可(ke)觀(guan)察(cha)鐵(tie)芯(xin)表(biao)麵(mian)有(you)無(wu)鏽(xiu)蝕(shi)斑(ban)或(huo)油(you)汙(wu)，若(ruo)有(you)則(ze)應(ying)擦(ca)去(qu)。或(huo)觀(guan)察(cha)短(duan)路(lu)環(huan)是(shi)否(fou)斷(duan)裂(lie)，斷(duan)裂(lie)的(de)要(yao)更(geng)換(huan)銜(xian)鐵(tie)及(ji)鐵(tie)芯(xin)。再(zai)可(ke)以(yi)看(kan)看(kan)反(fan)力(li)彈(dan)簧(huang)力(li)是(shi)否(fou)太(tai)大(da)
