金陽光電力電纜正常運行的重要因素是什么

     金(jin)陽光電(dian)力(li)(li)(li)電(dian)纜作(zuo)為(wei)連(lian)接各種電(dian)氣(qi)和傳(chuan)輸、分配電(dian)能的(de)設備，它的(de)穩(wen)定性(xing)高、安全維護工作(zuo)量(liang)少，能夠有效提高電(dian)能的(de)利用率和質量(liang)，并且還(huan)具有美(mei)化(hua)城市等(deng)特點。由于電(dian)力(li)(li)(li)系(xi)統正常(chang)運行的(de)重要(yao)因素就是電(dian)力(li)(li)(li)電(dian)纜，因此，在對電(dian)力(li)(li)(li)電(dian)纜進行故(gu)障(zhang)排除(chu)過程中采用的(de)技術，才能保障(zhang)電(dian)力(li)(li)(li)電(dian)纜故(gu)障(zhang)能夠及時(shi)解決。

1、負荷運行

  電(dian)流所具備的(de)熱(re)效應特點(dian)，會導(dao)致電(dian)流在通過電(dian)纜(lan)的(de)時候芯(xin)線發熱(re)，再加(jia)上電(dian)纜(lan)損(sun)(sun)耗(hao)過程中也(ye)會產生(sheng)一定(ding)的(de)熱(re)量，因此(ci)，在電(dian)纜(lan)在長期工作(zuo)中會產生(sheng)大(da)量熱(re)量，造成(cheng)溫(wen)度不斷升高，久而久之就造成(cheng)絕(jue)(jue)緣的(de)損(sun)(sun)壞，尤其是在夏季，其外部環境溫(wen)度高和(he)電(dian)纜(lan)本身溫(wen)度，通常就會造成(cheng)電(dian)纜(lan)發生(sheng)一定(ding)的(de)破(po)損(sun)(sun)現(xian)象。一般負(fu)荷運行(xing)所導(dao)致的(de)電(dian)纜(lan)損(sun)(sun)壞主要表(biao)現(xian)為以下幾點(dian)：（1）導(dao)線接點(dian)損(sun)(sun)壞;（2）電(dian)纜(lan)保(bao)護層(ceng)容易出現(xian)龜(gui)裂現(xian)象;（3）保(bao)護層(ceng)的(de)絕(jue)(jue)緣部位老化(hua)加(jia)速(su)。

2、金陽光電力電纜絕緣(yuan)介(jie)質受潮

      由于電(dian)力電(dian)纜(lan)(lan)的(de)(de)(de)(de)(de)接頭處本身(shen)的(de)(de)(de)(de)(de)質(zhi)(zhi)量(liang)問題以(yi)及安裝技術問題，通常情況下，電(dian)力電(dian)纜(lan)(lan)的(de)(de)(de)(de)(de)接頭處都(dou)會(hui)發生結構不密封(feng)的(de)(de)(de)(de)(de)現(xian)象。因此，就會(hui)導致電(dian)纜(lan)(lan)的(de)(de)(de)(de)(de)接頭處經常出現(xian)受潮的(de)(de)(de)(de)(de)現(xian)象。同時(shi)，電(dian)纜(lan)(lan)線也(ye)會(hui)存有一(yi)定(ding)的(de)(de)(de)(de)(de)缺陷，從(cong)而造成(cheng)了電(dian)纜(lan)(lan)的(de)(de)(de)(de)(de)絕緣介質(zhi)(zhi)其容易受到環(huan)境因素的(de)(de)(de)(de)(de)影響，從(cong)而使得電(dian)纜(lan)(lan)無法正常使用。

3、電力電纜過熱

      當(dang)電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)線路(lu)被鋪設到(dao)底下時，電(dian)(dian)纜(lan)(lan)(lan)的絕緣介質的內部(bu)就(jiu)(jiu)會經(jing)常出(chu)現(xian)(xian)氣隙游離的情況，進(jin)而就(jiu)(jiu)是嚴重(zhong)造成電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)出(chu)現(xian)(xian)局部(bu)過(guo)熱的問題(ti)。尤其(qi)是對于(yu)(yu)一(yi)些電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)內部(bu)通風(feng)速(su)度低于(yu)(yu)外(wai)部(bu)通風(feng)速(su)度的線路(lu)，其(qi)更加會容易(yi)出(chu)現(xian)(xian)電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)線路(lu)過(guo)熱的現(xian)(xian)象(xiang)。一(yi)旦電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)出(chu)現(xian)(xian)局部(bu)線路(lu)過(guo)熱，那么就(jiu)(jiu)容易(yi)導致線路(lu)外(wai)部(bu)絕緣體老化，從而降(jiang)低電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)外(wai)部(bu)絕緣效果。

4、機械損傷的原因

      當(dang)電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)投入到實際當(dang)中(zhong)(zhong)進行(xing)使(shi)(shi)用(yong)的(de)過程(cheng)中(zhong)(zhong)，往(wang)往(wang)會(hui)出(chu)現(xian)一些外部因素(su)造(zao)成電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)損(sun)傷的(de)情(qing)況。由于電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)接頭(tou)處或者絕緣處受(shou)到損(sun)傷，導(dao)致(zhi)嚴重影響(xiang)其(qi)正(zheng)常(chang)(chang)使(shi)(shi)用(yong)。通常(chang)(chang)情(qing)況下(xia)，電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)誤(wu)傷有以(yi)下(xia)幾方面：①其(qi)他施(shi)工(gong)項目(mu)在(zai)進行(xing)項目(mu)施(shi)工(gong)過程(cheng)中(zhong)(zhong)對電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)造(zao)成了誤(wu)傷。②在(zai)進行(xing)施(shi)工(gong)過程(cheng)中(zhong)(zhong)由于施(shi)工(gong)人(ren)員的(de)不(bu)規范操(cao)作使(shi)(shi)得電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)絕緣保護層出(chu)現(xian)了損(sun)傷。③由于一些自然因素(su)使(shi)(shi)得電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)接頭(tou)處或者是絕緣體受(shou)到傷害。
