電力電纜如何處理接頭發熱？湖北電纜生產廠家為大家詳細介紹：

1.如果發現觸(chu)點嚴重發熱(re)，請聯系變電(dian)站或(huo)應用單元，以降低該點線路(lu)的負載。

2.導線的連接(jie)應具有低(di)電阻和(he)足夠的沖擊(ji)韌性，接(jie)頭處不應有傾斜角度。

3.鉚接通(tong)常用于連(lian)接電(dian)纜導(dao)(dao)體。注：選(xuan)擇導(dao)(dao)電(dian)性和沖(chong)擊韌(ren)性合(he)適的導(dao)(dao)線連(lian)接管。

4.如果電(dian)纜本(ben)身有(you)內(nei)(nei)屏蔽(bi)層(ceng)(ceng)(ceng)，則在(zai)進行接(jie)(jie)(jie)頭(tou)時，有(you)必要重(zhong)新(xin)按壓對接(jie)(jie)(jie)導(dao)(dao)體(ti)(ti)(ti)的一(yi)部(bu)分(fen)接(jie)(jie)(jie)頭(tou)的內(nei)(nei)屏蔽(bi)層(ceng)(ceng)(ceng)，并且應空出(chu)電(dian)纜的一(yi)部(bu)分(fen)內(nei)(nei)半(ban)(ban)導(dao)(dao)體(ti)(ti)(ti)屏蔽(bi)，使連(lian)接(jie)(jie)(jie)管上接(jie)(jie)(jie)頭(tou)的內(nei)(nei)屏蔽(bi)層(ceng)(ceng)(ceng)相互連(lian)接(jie)(jie)(jie)，以保證內(nei)(nei)半(ban)(ban)導(dao)(dao)體(ti)(ti)(ti)的連(lian)續性，進而(er)使接(jie)(jie)(jie)頭(tou)對接(jie)(jie)(jie)處的磁場強度(du)均(jun)勻分(fen)布。外(wai)部(bu)半(ban)(ban)導(dao)(dao)體(ti)(ti)(ti)屏蔽(bi)層(ceng)(ceng)(ceng)是一(yi)種半(ban)(ban)導(dao)(dao)體(ti)(ti)(ti)原材料，在(zai)電(dian)纜和(he)(he)電(dian)纜接(jie)(jie)(jie)頭(tou)的絕(jue)緣層(ceng)(ceng)(ceng)外(wai)具有(you)均(jun)勻靜(jing)電(dian)場的作用。與內(nei)(nei)部(bu)半(ban)(ban)導(dao)(dao)體(ti)(ti)(ti)屏蔽(bi)一(yi)樣，它在(zai)電(dian)纜和(he)(he)接(jie)(jie)(jie)頭(tou)中起著非常關鍵的作用。外(wai)部(bu)半(ban)(ban)導(dao)(dao)體(ti)(ti)(ti)端口(kou)號必須(xu)整齊對稱(cheng)，并與絕(jue)緣層(ceng)(ceng)(ceng)平滑(hua)連(lian)接(jie)(jie)(jie)，在(zai)電(dian)纜接(jie)(jie)(jie)頭(tou)處增加半(ban)(ban)導(dao)(dao)體(ti)(ti)(ti)帶與電(dian)纜體(ti)(ti)(ti)外(wai)的半(ban)(ban)導(dao)(dao)體(ti)(ti)(ti)屏蔽(bi)鋼筋搭接(jie)(jie)(jie)連(lian)接(jie)(jie)(jie)。

5.接(jie)(jie)(jie)頭(tou)(tou)的(de)嚴密(mi)性和(he)機械(xie)設備的(de)維(wei)護(hu)是保(bao)證(zheng)接(jie)(jie)(jie)頭(tou)(tou)可靠運(yun)行的(de)保(bao)證(zheng)。應(ying)避免水和(he)水分(fen)滲入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜接(jie)(jie)(jie)頭(tou)(tou)。此(ci)外，應(ying)在接(jie)(jie)(jie)縫處修(xiu)建接(jie)(jie)(jie)縫維(wei)修(xiu)槽或(huo)混凝土維(wei)修(xiu)箱。運(yun)行經(jing)驗表明(ming)，低壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜故障(zhang)多為(wei)(wei)中間電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜接(jie)(jie)(jie)頭(tou)(tou)和(he)終端(duan)頭(tou)(tou)故障(zhang)，而中間接(jie)(jie)(jie)頭(tou)(tou)和(he)終端(duan)頭(tou)(tou)故障(zhang)多為(wei)(wei)密(mi)封不良和(he)水分(fen)侵入故障(zhang)，導致(zhi)絕緣(yuan)(yuan)強度下降(jiang)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜大部分(fen)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網絡采用樹(shu)枝狀供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)方式，具有大量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜終端(duan)。絕緣(yuan)(yuan)接(jie)(jie)(jie)頭(tou)(tou)的(de)絕緣(yuan)(yuan)結構和(he)尺寸與普通接(jie)(jie)(jie)頭(tou)(tou)相同。注(zhu)油電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜主絕緣(yuan)(yuan)接(jie)(jie)(jie)頭(tou)(tou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中，連(lian)接(jie)(jie)(jie)接(jie)(jie)(jie)頭(tou)(tou)的(de)兩端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜金屬(shu)護(hu)套或(huo)金屬(shu)屏蔽(bi)(bi)層(ceng)與半(ban)導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)層(ceng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)斷開交(jiao)叉互連(lian)，保(bao)護(hu)層(ceng)（或(huo)屏蔽(bi)(bi)層(ceng)）丟失。

電(dian)(dian)纜(lan)接(jie)頭(tou)是電(dian)(dian)纜(lan)線(xian)路中的(de)薄弱環(huan)節(jie)，施(shi)工不(bu)(bu)(bu)良引(yin)起(qi)的(de)電(dian)(dian)纜(lan)接(jie)頭(tou)破壞(huai)時有(you)發生(sheng)。在制作電(dian)(dian)纜(lan)接(jie)頭(tou)的(de)過(guo)程(cheng)中，如果接(jie)頭(tou)壓(ya)接(jie)不(bu)(bu)(bu)緊，加熱不(bu)(bu)(bu)充分，會降(jiang)低電(dian)(dian)纜(lan)頭(tou)的(de)絕(jue)緣性，造成事故。因此(ci)，封堵電(dian)(dian)纜(lan)終端和(he)中間接(jie)頭(tou)是保(bao)證電(dian)(dian)纜(lan)安(an)全可靠運行(xing)的(de)重要措施(shi)之一。
