籠式接線端子有(you)耐久性(xing)(xing)高、接線時間(jian)較(jiao)短的(de)(de)(de)特性(xing)(xing)，再加其(qi)耐高溫、抗腐(fu)蝕(shi)的(de)(de)(de)特性(xing)(xing)，被普遍應用(yong)在全球(qiu)保護(hu)接地行業。殊(shu)不(bu)知(zhi)籠式彈黃端(duan)子(zi)具體應用(yong)全過程中也(ye)存有(you)一些難題，端(duan)子(zi)燒蝕(shi)的(de)(de)(de)常(chang)見故(gu)障也(ye)常(chang)常(chang)產生，關鍵狀況是接線端(duan)子(zi)的(de)(de)(de)燒蝕(shi)、熔(rong)融等。下(xia)列就籠式端(duan)子(zi)發熱原因(yin)開展深入(ru)分析。

    一、壓進(jin)接線(xian)(xian)端子導線(xian)(xian)長短不(bu)符合要求規定

    籠(long)式接線(xian)(xian)(xian)端(duan)子(zi)擁(yong)有嚴(yan)苛(ke)的(de)過線(xian)(xian)(xian)長(chang)短規定(ding)，其相(xiang)匹配的(de)套(tao)接導(dao)(dao)線(xian)(xian)(xian)的(de)截面有實(shi)際的(de)范疇規定(ding)，例(li)如(ru)型號規格為(wei)(wei)(wei)285-635的(de)接線(xian)(xian)(xian)端(duan)子(zi)的(de)容許套(tao)接導(dao)(dao)線(xian)(xian)(xian)總面積為(wei)(wei)(wei)6～35毫米2。因而，當(dang)導(dao)(dao)線(xian)(xian)(xian)太細(xi)時，因為(wei)(wei)(wei)壓進導(dao)(dao)線(xian)(xian)(xian)的(de)太長(chang)，再加導(dao)(dao)線(xian)(xian)(xian)與觸碰總面積有電(dian)(dian)纜護套(tao)，導(dao)(dao)致導(dao)(dao)線(xian)(xian)(xian)的(de)導(dao)(dao)電(dian)(dian)能力惡變，進而損壞接線(xian)(xian)(xian)端(duan)子(zi)。例(li)如(ru)在(zai)配電(dian)(dian)箱開(kai)關(guan)電(dian)(dian)源主線(xian)(xian)(xian)任(ren)務接線(xian)(xian)(xian)處(chu)，彈黃(huang)端(duan)子(zi)選用285-635，開(kai)關(guan)電(dian)(dian)源主線(xian)(xian)(xian)任(ren)務為(wei)(wei)(wei)16mm2的(de)導(dao)(dao)線(xian)(xian)(xian)，就出(chu)現過相(xiang)近(jin)狀況，危險因素(su)巨大。

    二、插進接線(xian)端子的導(dao)線(xian)剝線(xian)長短不(bu)符合規定

    籠式彈黃端子對剝(bo)(bo)線(xian)(xian)(xian)(xian)的規定(ding)也較為(wei)嚴苛(ke)。例如型號規格為(wei)281-681型的接線(xian)(xian)(xian)(xian)端子的導(dao)線(xian)(xian)(xian)(xian)剝(bo)(bo)線(xian)(xian)(xian)(xian)長短(duan)為(wei)9～10毫(hao)米。剝(bo)(bo)線(xian)(xian)(xian)(xian)過短(duan)會使(shi)彈黃套(tao)接總面積(ji)過小，非(fei)常容易導(dao)致顯著(zhu)的掉(diao)下(xia)來。針對剝(bo)(bo)線(xian)(xian)(xian)(xian)，不但要有豐(feng)富多彩(cai)的實際操作工作經(jing)驗，還(huan)務(wu)必配置專(zhuan)業的剝(bo)(bo)線(xian)(xian)(xian)(xian)專(zhuan)用工具，以固定(ding)不動剝(bo)(bo)線(xian)(xian)(xian)(xian)長短(duan)。

    三、對插進接線(xian)端子的(de)導線(xian)截面不符(fu)合(he)規定

    籠式彈黃(huang)端(duan)(duan)(duan)子(zi)對套(tao)接(jie)導線(xian)(xian)的截(jie)面擁有(you)嚴(yan)苛的范疇規定(ding)(ding)，若(ruo)超(chao)出規定(ding)(ding)的范疇，會使(shi)導線(xian)(xian)的接(jie)線(xian)(xian)邊緣不可以徹底插(cha)進(jin)(jin)接(jie)線(xian)(xian)端(duan)(duan)(duan)子(zi)孔壁，導致導電能力降低，種(zhong)下安(an)全(quan)風險。在(zai)鐵路(lu)客車上，導線(xian)(xian)總(zong)(zong)數通常較多(duo)，當籠式端(duan)(duan)(duan)子(zi)總(zong)(zong)數低于導線(xian)(xian)壓入量規定(ding)(ding)時，肯(ken)定(ding)(ding)不允(yun)許(xu)把二根導線(xian)(xian)擰在(zai)一(yi)起(qi)插(cha)進(jin)(jin)到一(yi)個接(jie)線(xian)(xian)端(duan)(duan)(duan)子(zi)插(cha)口(kou)中。
