使用斷路器要注意以下這些情況的發生

　　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)的(de)常(chang)見(jian)故(gu)障(zhang)為(wei)不(bu)能(neng)合(he)閘(zha)。這(zhe)種(zhong)故(gu)障(zhang)發(fa)生(sheng)的(de)原(yuan)因(yin)有(you)欠(qian)壓(ya)脫(tuo)扣(kou)器(qi)無(wu)電(dian)壓(ya)或(huo)者(zhe)是(shi)線(xian)圈(quan)損(sun)壞(huai)
，反(fan)作(zuo)用(yong)力(li)彈(dan)簧(huang)力(li)過(guo)大(da)
，或(huo)者(zhe)機(ji)構(gou)不(bu)能(neng)複(fu)位(wei)再(zai)扣(kou)等(deng)。修(xiu)複(fu)的(de)方(fang)法(fa)是(shi)檢(jian)查(zha)調(tiao)換(huan)電(dian)源(yuan)電(dian)壓(ya)，更(geng)換(huan)線(xian)圈(quan)或(huo)重(zhong)新(xin)調(tiao)整(zheng)彈(dan)簧(huang)，對(dui)於(yu)機(ji)構(gou)不(bu)能(neng)複(fu)位(wei)再(zai)扣(kou)的(de)情(qing)況(kuang)，應(ying)調(tiao)整(zheng)再(zai)扣(kou)接(jie)觸(chu)麵(mian)到(dao)規(gui)定(ding)值(zhi)。

　　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。
