在我國北方(fang)地區，冬季地面結冰，因此當直埋(mai)電(dian)(dian)纜(lan)(lan)(lan)發生(sheng)故障(zhang)(zhang)時，實(shi)際(ji)(ji)(ji)的(de)(de)故障(zhang)(zhang)查找(zhao)和處理(li)過程(cheng)實(shi)際(ji)(ji)(ji)上(shang)是(shi)一項非常艱巨的(de)(de)工作。首先(xian)，所(suo)使用的(de)(de)電(dian)(dian)纜(lan)(lan)(lan)故障(zhang)(zhang)定位儀(yi)(yi)必須具有(you)較高(gao)的(de)(de)精度，其次(ci)，必須有(you)相應的(de)(de)人員(yuan)對(dui)(dui)(dui)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)實(shi)際(ji)(ji)(ji)敷(fu)設路線(xian)(xian)有(you)明確的(de)(de)了解(jie)。雖然一些電(dian)(dian)纜(lan)(lan)(lan)故障(zhang)(zhang)檢測(ce)儀(yi)(yi)器(qi)配(pei)備了電(dian)(dian)纜(lan)(lan)(lan)路徑測(ce)試儀(yi)(yi)，但也需要對(dui)(dui)(dui)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)大致敷(fu)設路徑了解(jie)的(de)(de)現場人員(yuan)給予(yu)配(pei)合，才能提高(gao)對(dui)(dui)(dui)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)定位精度，在實(shi)際(ji)(ji)(ji)處理(li)電(dian)(dian)纜(lan)(lan)(lan)故障(zhang)(zhang)的(de)(de)過程(cheng)中，往往是(shi)三成(cheng)靠人，七成(cheng)靠機器(qi)。

目前(qian)，市場(chang)上(shang)生產(chan)和(he)銷售電(dian)纜(lan)故(gu)(gu)障檢測(ce)儀的廠家很(hen)多(duo)，檢測(ce)儀的類型(xing)也(ye)多(duo)種多(duo)樣，但在現實(shi)(shi)操(cao)作(zuo)中，并不能對所有電(dian)纜(lan)故(gu)(gu)障進行定(ding)位。在實(shi)(shi)際(ji)使(shi)用中，它往往只對一種或幾種類型(xing)的故(gu)(gu)障定(ding)位有效，對某些故(gu)(gu)障仍然無能為力。目前(qian)電(dian)力使(shi)用部門寧(ning)愿投(tou)入大量資(zi)金，也(ye)想(xiang)購買一臺功能齊全、定(ding)位精度高的通(tong)用電(dian)纜(lan)故(gu)(gu)障測(ce)試儀，以便快速、有效地解決(jue)所有實(shi)(shi)際(ji)電(dian)纜(lan)故(gu)(gu)障，但實(shi)(shi)際(ji)上(shang)很(hen)難得到。

市(shi)場(chang)上(shang)雖有不斷更(geng)新的(de)電(dian)纜(lan)(lan)故障(zhang)檢(jian)(jian)測(ce)(ce)儀(yi)(yi)，然(ran)而(er)現場(chang)實(shi)際檢(jian)(jian)測(ce)(ce)仍然(ran)會遇到一些技術(shu)上(shang)的(de)難題(ti)。原因主要來自(zi)兩(liang)個方面：一是電(dian)纜(lan)(lan)及其附(fu)件中使用的(de)各種絕緣、填充和(he)包裝(zhuang)材料不斷發展和(he)更(geng)新，導致電(dian)纜(lan)(lan)故障(zhang)類型不斷變化。二是電(dian)纜(lan)(lan)故障(zhang)檢(jian)(jian)測(ce)(ce)儀(yi)(yi)的(de)市(shi)場(chang)需求有限，相關研發人(ren)員稀缺(que)，導致便(bian)攜式(shi)、高(gao)精(jing)度(du)、智能(neng)化、多(duo)功能(neng)電(dian)纜(lan)(lan)故障(zhang)檢(jian)(jian)測(ce)(ce)儀(yi)(yi)的(de)上(shang)市(shi)時間推(tui)遲。

相信(xin)隨著智能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)網(wang)時代的(de)(de)(de)到來和電(dian)(dian)(dian)(dian)(dian)纜(lan)故(gu)障檢(jian)測技術(shu)的(de)(de)(de)飛速發展，電(dian)(dian)(dian)(dian)(dian)纜(lan)故(gu)障定位將會成為一件(jian)非常簡單和容(rong)易的(de)(de)(de)事情(qing)。說(shuo)到這里，不(bu)難發現一個問(wen)題，也就是電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)質(zhi)量(liang)尤其關鍵，既然(ran)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)故(gu)障檢(jian)測存在很多(duo)不(bu)確定性，那(nei)我們能(neng)(neng)做的(de)(de)(de)就是在購買電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)時盡(jin)可能(neng)(neng)選擇質(zhi)量(liang)好的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)，減(jian)(jian)少電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)故(gu)障發生率(lv)，也就能(neng)(neng)減(jian)(jian)少很多(duo)不(bu)必要的(de)(de)(de)麻煩。
