配電柜接線端子是(shi)配電柜內(nei)部重(zhong)要的(de)組(zu)成零(ling)配件，正(zheng)因(yin)為如此，配電柜內(nei)的(de)接線(xian)端子很(hen)容易造(zao)成發(fa)熱燒損(sun)常見(jian)問題，原(yuan)文(wen)中(zhong)將重(zhong)要講講配電柜接線(xian)端子造(zao)成燒損(sun)常見(jian)問題的(de)原(yuan)因(yin)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下方面：

    1、載(zai)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)導(dao)(dao)(dao)體(ti)發熱(re)方(fang)面：因電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源變壓(ya)器轉換柜里主干路簧片(pian)(pian)式籠式接(jie)線(xian)端子聯接(jie)的走線(xian)均為16m，簧片(pian)(pian)延展(zhan)性非(fei)常大(da)，在走線(xian)接(jie)人(ren)時(shi)簧片(pian)(pian)開啟角度(du)不夠(gou)，造成走線(xian)一部分電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)導(dao)(dao)(dao)體(ti)（多銅(tong)芯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜）未(wei)壓(ya)人(ren)簧片(pian)(pian)內，造成實(shi)際導(dao)(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)率占地面積降(jiang)低，依據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)總(zong)流量時(shi)導(dao)(dao)(dao)致(zhi)(zhi)發現(xian)異常提溫。實(shi)驗確認(ren)，金(jin)屬復合材料電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)導(dao)(dao)(dao)體(ti)在高溫下(xia)因遭受熱(re)處(chu)理(li)從而其(qi)斷裂(lie)韌性減少，銅(tong)超過(guo)巧0時(shi)，其(qi)斷裂(lie)韌性急劇(ju)下(xia)降(jiang)，使(shi)簧片(pian)(pian)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)導(dao)(dao)(dao)體(ti)間碰觸處(chu)壓(ya)力降(jiang)低，回路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻擴張，導(dao)(dao)(dao)致(zhi)(zhi)發熱(re)更為情況(kuang)嚴重。此外，由于發熱(re)使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)導(dao)(dao)(dao)體(ti)碰觸表(biao)面顯著氧化，導(dao)(dao)(dao)致(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)導(dao)(dao)(dao)體(ti)本身(shen)大(da)許多 的氯(lv)化銅(tong)，使(shi)回路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻大(da)大(da)增(zeng)加，造成碰觸處(chu)發熱(re)激增(zeng)，造成兩極分化，使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)導(dao)(dao)(dao)體(ti)碰觸處(chu)松動、變形、甚至生產(chan)率熔化情況(kuang)。

    籠式(shi)(shi)接(jie)(jie)線(xian)端(duan)(duan)子回路電(dian)阻方面：因走(zou)線(xian)的電(dian)導(dao)(dao)體與簧片（插口(kou)）為線(xian)碰(peng)觸(chu)，并不是面碰(peng)觸(chu)，電(dian)導(dao)(dao)體進到簧片（插口(kou)）內(nei)太長或(huo)太短(duan)期內(nei)，簧片（插口(kou)）的卡力(li)距不能使走(zou)線(xian)電(dian)導(dao)(dao)體與籠式(shi)(shi)接(jie)(jie)線(xian)端(duan)(duan)子內(nei)部的電(dian)導(dao)(dao)體造(zao)成優質的碰(peng)觸(chu)，回路電(dian)阻提高，長久性依據電(dian)總流量時，易造(zao)成籠式(shi)(shi)接(jie)(jie)線(xian)端(duan)(duan)子發現異常發熱(re)、燒損。

    3、籠(long)式(shi)電(dian)阻卡死壓(ya)絕緣套管發(fa)熱方(fang)面：走(zou)線的電(dian)導體進到簧片（插口(kou)）時(shi)，簧片（插口(kou)）壓(ya)著一部分走(zou)線的絕緣套管，因(yin)絕緣套管有一定的厚薄，使簧片（插口(kou)）鉚壓(ya)走(zou)線電(dian)導體的卡力距不夠，回路電(dian)阻提高，長久性(xing)依據電(dian)總流(liu)量時(shi)，易造成籠(long)式(shi)接線端(duan)子發(fa)現異常(chang)發(fa)熱、燒(shao)損。

    除了(le)以(yi)上的這(zhe)類原因以(yi)外，也是(shi)(shi)有(you)一些其他的因素也會導致(zhi)配電柜接(jie)(jie)線(xian)端(duan)子造(zao)成(cheng)燒損常見問題，在這(zhe)兒就(jiu)沒有(you)詳細說(shuo)明了(le)，避免出現配電柜接(jie)(jie)線(xian)端(duan)子造(zao)成(cheng)燒損常見問題最行(xing)之有(you)效的方式 就(jiu)是(shi)(shi)事前多檢查(cha)。"
