配電柜接線端子是配(pei)電(dian)柜(ju)內部(bu)重要的(de)組成(cheng)零配(pei)件，正因為(wei)如(ru)此，配(pei)電(dian)柜(ju)內的(de)接(jie)線端子(zi)很容易(yi)造成(cheng)發(fa)熱燒損(sun)常(chang)見問題，原(yuan)文中將重要講講配(pei)電(dian)柜(ju)接(jie)線端子(zi)造成(cheng)燒損(sun)常(chang)見問題的(de)原(yuan)因分析(xi)。

    籠式彈黃接線端子走線方便快捷、結構緊湊，因為運用廣泛，但由于接線端子正中間連接緊湊，內部燒損時在表面不易發現，易造成較情況嚴重的燒損，造成歐式接線端子燒損的原因重要有以(yi)下(xia)方面：

    1、載流電(dian)(dian)(dian)(dian)導(dao)(dao)(dao)(dao)體(ti)發熱(re)方面：因電(dian)(dian)(dian)(dian)源(yuan)變壓(ya)器轉換柜(ju)里主干路(lu)(lu)簧(huang)片式籠式接(jie)(jie)線端子聯接(jie)(jie)的(de)(de)走(zou)(zou)線均為16m，簧(huang)片延展性非(fei)常大(da)，在(zai)走(zou)(zou)線接(jie)(jie)人時(shi)簧(huang)片開啟(qi)角(jiao)度不夠，造成走(zou)(zou)線一部分電(dian)(dian)(dian)(dian)導(dao)(dao)(dao)(dao)體(ti)（多銅芯電(dian)(dian)(dian)(dian)纜）未(wei)壓(ya)人簧(huang)片內，造成實(shi)際導(dao)(dao)(dao)(dao)電(dian)(dian)(dian)(dian)率占(zhan)地面積降低，依據電(dian)(dian)(dian)(dian)總(zong)流量時(shi)導(dao)(dao)(dao)(dao)致(zhi)發現(xian)異(yi)常提(ti)溫(wen)。實(shi)驗確認，金(jin)屬復合(he)材(cai)料電(dian)(dian)(dian)(dian)導(dao)(dao)(dao)(dao)體(ti)在(zai)高溫(wen)下(xia)因遭受熱(re)處理(li)從(cong)而其斷(duan)裂韌性減(jian)少，銅超過巧(qiao)0時(shi)，其斷(duan)裂韌性急劇下(xia)降，使簧(huang)片與電(dian)(dian)(dian)(dian)導(dao)(dao)(dao)(dao)體(ti)間碰觸處壓(ya)力(li)降低，回(hui)路(lu)(lu)電(dian)(dian)(dian)(dian)阻(zu)(zu)擴張，導(dao)(dao)(dao)(dao)致(zhi)發熱(re)更為情況嚴(yan)重。此外，由于發熱(re)使電(dian)(dian)(dian)(dian)導(dao)(dao)(dao)(dao)體(ti)碰觸表面顯著氧化(hua)，導(dao)(dao)(dao)(dao)致(zhi)電(dian)(dian)(dian)(dian)阻(zu)(zu)比電(dian)(dian)(dian)(dian)導(dao)(dao)(dao)(dao)體(ti)本身大(da)許多 的(de)(de)氯化(hua)銅，使回(hui)路(lu)(lu)電(dian)(dian)(dian)(dian)阻(zu)(zu)大(da)大(da)增加，造成碰觸處發熱(re)激增，造成兩極(ji)分化(hua)，使電(dian)(dian)(dian)(dian)導(dao)(dao)(dao)(dao)體(ti)碰觸處松動、變形、甚至生產率熔化(hua)情況。

    籠式(shi)接(jie)(jie)線(xian)(xian)端子(zi)回路電(dian)阻(zu)(zu)方面：因(yin)走線(xian)(xian)的電(dian)導體與(yu)簧片(pian)（插口(kou)）為線(xian)(xian)碰觸(chu)(chu)(chu)，并不是(shi)面碰觸(chu)(chu)(chu)，電(dian)導體進到簧片(pian)（插口(kou)）內(nei)(nei)太(tai)長(chang)或(huo)太(tai)短期內(nei)(nei)，簧片(pian)（插口(kou)）的卡力(li)距(ju)不能使(shi)走線(xian)(xian)電(dian)導體與(yu)籠式(shi)接(jie)(jie)線(xian)(xian)端子(zi)內(nei)(nei)部的電(dian)導體造成(cheng)優質(zhi)的碰觸(chu)(chu)(chu)，回路電(dian)阻(zu)(zu)提高，長(chang)久性依據電(dian)總流量時，易造成(cheng)籠式(shi)接(jie)(jie)線(xian)(xian)端子(zi)發(fa)現(xian)異常發(fa)熱、燒(shao)損。

    3、籠式(shi)電(dian)(dian)(dian)阻卡死(si)壓(ya)絕(jue)緣套管(guan)(guan)發(fa)(fa)熱方面：走(zou)線(xian)(xian)的(de)電(dian)(dian)(dian)導(dao)體進(jin)到簧(huang)(huang)片（插(cha)口）時，簧(huang)(huang)片（插(cha)口）壓(ya)著一(yi)部分走(zou)線(xian)(xian)的(de)絕(jue)緣套管(guan)(guan)，因(yin)絕(jue)緣套管(guan)(guan)有一(yi)定的(de)厚薄，使簧(huang)(huang)片（插(cha)口）鉚壓(ya)走(zou)線(xian)(xian)電(dian)(dian)(dian)導(dao)體的(de)卡力距不夠，回路電(dian)(dian)(dian)阻提高，長久(jiu)性依(yi)據(ju)電(dian)(dian)(dian)總(zong)流量時，易造成籠式(shi)接線(xian)(xian)端子(zi)發(fa)(fa)現異常發(fa)(fa)熱、燒損。

    除了以(yi)上(shang)的(de)(de)這(zhe)類原因以(yi)外，也是(shi)有一些其(qi)他(ta)的(de)(de)因素也會(hui)導致配電柜接線(xian)(xian)端(duan)(duan)子造(zao)成燒(shao)損常(chang)見(jian)問(wen)題，在(zai)這(zhe)兒就(jiu)沒有詳(xiang)細(xi)說(shuo)明了，避免出(chu)現配電柜接線(xian)(xian)端(duan)(duan)子造(zao)成燒(shao)損常(chang)見(jian)問(wen)題最(zui)行之有效的(de)(de)方式 就(jiu)是(shi)事前多檢查。"
