一、造成燒黑：

    假如接線端子黑(hei)了，在其中的一種概率并(bing)不一定是燒黑(hei)，空氣氧化也很有可(ke)能黑(hei)。那(nei)麼如何去(qu)認證是否燒黑(hei)的呢(ni)?大(da)家采用的方式是用手指一擦(ca)，假如能擦(ca)下(xia)去(qu)，象香灰(hui)一樣，那(nei)便是被氧化而(er)產生的灰(hui)黑(hei)色化學物質，得(de)用打磨砂(sha)紙或是挫刀(dao)才可(ke)以磨去(qu)。

    南京市三門灣(wan)的接(jie)線端(duan)(duan)子(zi)權威專家友情提示，這兒要(yao)留意的一(yi)(yi)點是(shi)：感應起電(dian)的情況(kuang)下可千萬不要(yao)用手指(zhi)去擦！那麼(ma)此外(wai)的一(yi)(yi)種概率便是(shi)燒(shao)黑了，除開(kai)火災(zai)事故和氣功大師發(fa)功以外(wai)，僅有一(yi)(yi)種很有可能，便是(shi)接(jie)線端(duan)(duan)子(zi)超溫(wen)高溫(wen)了。

    二、柵欄式接線端子造成高溫的難題：

    有(you)二種很有(you)可能：接線(xian)端子松(song)脫導(dao)致回(hui)路電(dian)阻過(guo)大，進而(er)超溫；接線(xian)端子未松(song)脫，可是控(kong)制回(hui)路因(yin)某類(lei)不(bu)明緣(yuan)故(gu)而(er)過(guo)電(dian)流量(liang)發燙，比如電(dian)源電(dian)壓過(guo)高了，或(huo)是負荷(he)短路故(gu)障了。

    1、工作電(dian)(dian)(dian)(dian)壓(ya)過高。能夠(gou)從根源查(cha)實，變電(dian)(dian)(dian)(dian)器(qi)次級(ji)線(xian)圈(quan)工作電(dian)(dian)(dian)(dian)壓(ya)-配電(dian)(dian)(dian)(dian)柜(ju)內(nei)工作電(dian)(dian)(dian)(dian)壓(ya)-各用電(dian)(dian)(dian)(dian)量機器(qi)設備工作電(dian)(dian)(dian)(dian)壓(ya)。電(dian)(dian)(dian)(dian)源插(cha)(cha)座還可以有安(an)裝扣(kou)位(wei)和鎖(suo)住(zhu)扣(kou)位(wei)。安(an)裝扣(kou)位(wei)能夠(gou)具有更為牢(lao)固(gu)地固(gu)定(ding)不(bu)動到PCB板上，鎖(suo)住(zhu)扣(kou)位(wei)能夠(gou)在安(an)裝進行(xing)后鎖(suo)住(zhu)孕媽和電(dian)(dian)(dian)(dian)源插(cha)(cha)座。各式各樣的電(dian)(dian)(dian)(dian)源插(cha)(cha)座設計方案能夠(gou)配搭不(bu)一樣孕媽的插(cha)(cha)入方法，例如：水準、豎直或歪斜向印刷線(xian)路板等。既能夠(gou)挑選公英制線(xian)軌(gui)還可以挑選規范線(xian)軌(gui)。

    2、接(jie)(jie)地(di)(di)常見故障。還可以從變電(dian)(dian)(dian)器(qi)那(nei)邊(bian)查實(shi)，隨后到配(pei)電(dian)(dian)(dian)柜(ju)接(jie)(jie)地(di)(di)。該(gai)接(jie)(jie)地(di)(di)的要(yao)接(jie)(jie)地(di)(di)，而一切正常的火線(xian)(xian)(xian)零線(xian)(xian)(xian)則應(ying)清除接(jie)(jie)地(di)(di)常見故障。能夠(gou)關閉電(dian)(dian)(dian)源時要(yao)絕緣層表或接(jie)(jie)地(di)(di)搖表來精準測(ce)(ce)量，分段(duan)精準測(ce)(ce)量，盡(jin)可能只分段(duan)精準測(ce)(ce)量電(dian)(dian)(dian)纜線(xian)(xian)(xian)、電(dian)(dian)(dian)纜線(xian)(xian)(xian)、隔離開關、電(dian)(dian)(dian)源開關等供配(pei)電(dian)(dian)(dian)系統路線(xian)(xian)(xian)，確實(shi)無法分段(duan)的狀(zhuang)況(kuang)下，則拔出弱(ruo)電(dian)(dian)(dian)安(an)裝機(ji)器(qi)設(she)備、傳感技(ji)術機(ji)器(qi)設(she)備的保險管。
