為了(le)滿足(zu)配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)發展的(de)需求，采用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)已成為必然趨勢(shi)。通過建立以(yi)高壓開(kai)(kai)關柜(ju)配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)模式(shi)為主的(de)配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)絡，實現(xian)在復雜網(wang)架下故(gu)障(zhang)(zhang)的(de)快速(su)處理和恢復，大大縮短了(le)停電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間。目前，配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)高壓開(kai)(kai)關柜(ju)以(yi)其可(ke)靠(kao)性和經濟性成為配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)絡電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)化的(de)首選形式(shi)，與此(ci)同(tong)時(shi)，對配(pei)(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)高壓開(kai)(kai)關柜(ju)可(ke)靠(kao)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)要求也愈(yu)來愈(yu)高。隨著城(cheng)市(shi)化的(de)發展，在城(cheng)區的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)大都(dou)從(cong)架空線路(lu)轉入(ru)到地下線路(lu)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)在配(pei)(pei)(pei)(pei)網(wang)系(xi)統(tong)中廣泛(fan)應用(yong)，其安全(quan)運行對于用(yong)戶(hu)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)可(ke)靠(kao)性非(fei)常重要。根(gen)據多年來電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)故(gu)障(zhang)(zhang)的(de)數據統(tong)計可(ke)以(yi)看出，致使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)產生故(gu)障(zhang)(zhang)最根(gen)本的(de)緣由是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)中間接頭的(de)故(gu)障(zhang)(zhang)。

隧(sui)道(dao)電纜故(gu)障的原因：

1、在鋪設的(de)過程中電纜接頭(tou)常(chang)(chang)常(chang)(chang)會因(yin)施(shi)工工藝(yi)不良從而致使裝(zhuang)設的(de)中間(jian)接頭(tou)存在某些缺陷。

2、中間(jian)接(jie)頭(tou)(tou)多數處于地(di)下(xia)電(dian)纜(lan)(lan)溝中，環境較(jiao)為(wei)惡(e)劣，淤泥雨(yu)水對(dui)中間(jian)接(jie)頭(tou)(tou)的長期腐(fu)蝕，造成絕緣老化損壞，出現(xian)內部(bu)絕緣缺陷。這兩(liang)種情況均會導(dao)致(zhi)局部(bu)放電(dian)現(xian)象(xiang)的產生，進而(er)(er)不(bu)斷腐(fu)蝕電(dian)纜(lan)(lan)的絕緣層，使其絕緣性能出現(xian)大(da)幅下(xia)降，從而(er)(er)引起電(dian)纜(lan)(lan)運行故(gu)障，造成停電(dian)事(shi)故(gu)。因此針對(dui)電(dian)纜(lan)(lan)井電(dian)纜(lan)(lan)接(jie)頭(tou)(tou)的溫度監測(ce)顯得尤為(wei)重要(yao)。

日常工(gong)(gong)作(zuo)中，電(dian)力系統(tong)運維人員通過(guo)定期到(dao)場巡檢電(dian)纜(lan)(lan)接(jie)(jie)頭溫(wen)(wen)(wen)(wen)度(du)值、接(jie)(jie)頭老化(hua)情況、工(gong)(gong)作(zuo)量較(jiao)(jiao)大、且工(gong)(gong)作(zuo)效率較(jiao)(jiao)低，無法實現實時溫(wen)(wen)(wen)(wen)度(du)監測(ce)需(xu)求，也不(bu)能(neng)及(ji)時發現問(wen)題，解決問(wen)題。電(dian)纜(lan)(lan)接(jie)(jie)頭運行(xing)溫(wen)(wen)(wen)(wen)度(du)監測(ce)方(fang)法較(jiao)(jiao)多，常用方(fang)法有紅(hong)外測(ce)溫(wen)(wen)(wen)(wen)法，紅(hong)外測(ce)溫(wen)(wen)(wen)(wen)法的原理(li)是當故障(zhang)點形(xing)成溫(wen)(wen)(wen)(wen)度(du)源后，通過(guo)測(ce)量溫(wen)(wen)(wen)(wen)度(du)源紅(hong)外輻射波(bo)獲得溫(wen)(wen)(wen)(wen)度(du)變化(hua)，缺點是不(bu)能(neng)實現在線(xian)測(ce)溫(wen)(wen)(wen)(wen)，需(xu)要人工(gong)(gong)巡檢，耗工(gong)(gong)費時。

華(hua)光(guang)(guang)天銳自(zi)主(zhu)研發的電纜接(jie)頭(tou)熒光(guang)(guang)光(guang)(guang)纖(xian)測溫(wen)裝置(zhi)和變送器模塊具有更低(di)的功率消耗，更加省電，使用壽命長，耐高(gao)壓、抗干(gan)擾、絕(jue)緣、測溫(wen)探頭(tou)無金屬，光(guang)(guang)纖(xian)本質(zhi)安(an)全(quan)，便于系統(tong)的維護，降(jiang)低(di)運行成本。
