高壓電(dian)(dian)力電(dian)(dian)纜(lan)在使用過程中，假如(ru)發生故(gu)障就會馬上造成短路(lu)故(gu)障，直接影(ying)響輸電(dian)(dian)工作(zuo)，因而需(xu)要(yao)及時(shi)尋找到故(gu)障點(dian)并(bing)立(li)即(ji)進(jin)行排(pai)除，需(xu)要(yao)用到電(dian)(dian)纜(lan)故(gu)障測試儀(yi)(yi)，該設備主(zhu)要(yao)是用于進(jin)行高壓電(dian)(dian)力電(dian)(dian)纜(lan)的故(gu)障點(dian)的查找工作(zuo)，具備速度快并(bing)且準確度高等特點(dian)，深(shen)受廣大客(ke)戶朋友們的歡迎(ying)，那具體來說電(dian)(dian)纜(lan)故(gu)障測試儀(yi)(yi)是如(ru)何(he)工作(zuo)的呢(ni)？給大家簡單介紹一下。

電(dian)(dian)(dian)(dian)纜(lan)故(gu)障(zhang)測(ce)(ce)試(shi)儀可以(yi)減少尺寸，降低(di)了直流(liu)電(dian)(dian)(dian)(dian)源(yuan)的(de)，電(dian)(dian)(dian)(dian)纜(lan)可以(yi)被用來(lai)檢(jian)測(ce)(ce)各種低(di)電(dian)(dian)(dian)(dian)阻，高(gao)(gao)電(dian)(dian)(dian)(dian)阻，短路(lu)故(gu)障(zhang)，開路(lu)，漏電(dian)(dian)(dian)(dian)保護故(gu)障(zhang)和閃絡故(gu)障(zhang)可以(yi)探測(ce)(ce)地下的(de)電(dian)(dian)(dian)(dian)纜(lan)故(gu)障(zhang)定位(wei)，鋪設電(dian)(dian)(dian)(dian)纜(lan)長度和電(dian)(dian)(dian)(dian)纜(lan)路(lu)徑(jing)。這就是我們一(yi)貫的(de)高(gao)(gao)科技(ji)，高(gao)(gao)精(jing)度，高(gao)(gao)品質的(de)宗(zong)旨，以(yi)提高(gao)(gao)電(dian)(dian)(dian)(dian)纜(lan)的(de)水平(ping)測(ce)(ce)試(shi)一(yi)個(ge)(ge)新的(de)境(jing)界(jie)。它(ta)有(you)一(yi)個(ge)(ge)檢(jian)測(ce)(ce)準確(que)，智能化程度高(gao)(gao)，適應面(mian)廣，相對穩定的(de)性能和輕(qing)巧便攜的(de)特(te)性。

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜故(gu)(gu)(gu)障(zhang)(zhang)測(ce)(ce)試儀主(zhu)要用的(de)(de)是(shi)沖閃法(fa)適用于(yu)(yu)進行測(ce)(ce)試高(gao)(gao)阻(zu)泄(xie)漏性(xing)故(gu)(gu)(gu)障(zhang)(zhang)，對于(yu)(yu)其他(ta)企業類型并沒有高(gao)(gao)低(di)阻(zu)故(gu)(gu)(gu)障(zhang)(zhang)也(ye)可(ke)用沖閃法(fa)檢(jian)測(ce)(ce)。檢(jian)測(ce)(ce)研究方法(fa)與(yu)直閃法(fa)相同，只不過(guo)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜不是(shi)加(jia)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源系(xi)統高(gao)(gao)壓(ya)(ya)而是(shi)可(ke)以通過(guo)球(qiu)間隙施(shi)加(jia)一定沖擊電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，使故(gu)(gu)(gu)障(zhang)(zhang)點(dian)擊穿放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而產生影響反(fan)射電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)（或者一個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)），由儀器(qi)設備記錄我們這一問題瞬(shun)間狀態的(de)(de)過(guo)程，通過(guo)不同波(bo)形圖(tu)數據分析來測(ce)(ce)定故(gu)(gu)(gu)障(zhang)(zhang)點(dian)的(de)(de)位置。它(ta)是(shi)測(ce)(ce)高(gao)(gao)阻(zu)及閃絡(luo)性(xing)故(gu)(gu)(gu)障(zhang)(zhang)的(de)(de)主(zhu)要學(xue)習方法(fa)。更(geng)加(jia)需要取(qu)(qu)(qu)樣(yang)(yang)(yang)管(guan)理(li)方式也(ye)分電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)取(qu)(qu)(qu)樣(yang)(yang)(yang)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)取(qu)(qu)(qu)樣(yang)(yang)(yang)，當然市(shi)場細分還可(ke)分為低(di)端(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)取(qu)(qu)(qu)樣(yang)(yang)(yang)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)取(qu)(qu)(qu)樣(yang)(yang)(yang)，始端(duan)(duan)與(yu)終端(duan)(duan)設備取(qu)(qu)(qu)樣(yang)(yang)(yang)等(deng)。因為我國(guo)中(zhong)低(di)端(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)取(qu)(qu)(qu)樣(yang)(yang)(yang)接(jie)線簡便(bian)(bian)、安全可(ke)靠信息安全、波(bo)形圖(tu)便(bian)(bian)于(yu)(yu)學(xue)生識別，因此他(ta)們推薦使用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)取(qu)(qu)(qu)樣(yang)(yang)(yang)法(fa)。

在使用(yong)機器設備(bei)的(de)時候根據(ju)顯(xian)示波(bo)(bo)(bo)形(xing)圖大小，調節(jie)幅度電(dian)(dian)(dian)(dian)位(wei)器，重新采(cai)樣(yang)。當0.2us脈(mo)寬輸(shu)入幅度為(wei)(wei)反(fan)射波(bo)(bo)(bo)時，選(xuan)(xuan)擇2us脈(mo)沖測試。為(wei)(wei)了能進行(xing)對比(bi)，能夠對故(gu)障相(xiang)(xiang)位(wei)和(he)其他良好相(xiang)(xiang)位(wei)進行(xing)兩次(ci)采(cai)樣(yang)。選(xuan)(xuan)擇單波(bo)(bo)(bo)形(xing)圖或(huo)(huo)雙波(bo)(bo)(bo)形(xing)圖顯(xian)示，用(yong)1/2鍵改(gai)變操(cao)作區域，選(xuan)(xuan)擇電(dian)(dian)(dian)(dian)流波(bo)(bo)(bo)形(xing)1或(huo)(huo)2。采(cai)樣(yang)后，移動(dong)(dong)光(guang)校準(zhun)起點(dian)(dian)(dian)，再將光(guang)標移動(dong)(dong)到波(bo)(bo)(bo)形(xing)圖反(fan)射點(dian)(dian)(dian)，這個時候屏幕上(shang)(shang)顯(xian)示的(de)長(chang)度為(wei)(wei)電(dian)(dian)(dian)(dian)纜(lan)(lan)全長(chang)值。相(xiang)(xiang)對于短(duan)電(dian)(dian)(dian)(dian)纜(lan)(lan)，要測量終(zhong)端設備(bei)短(duan)路(lu)(lu)故(gu)障的(de)總長(chang)度，將終(zhong)端設備(bei)反(fan)射改(gai)為(wei)(wei)負(fu)脈(mo)沖，當光(guang)標固定時，光(guang)標的(de)起點(dian)(dian)(dian)為(wei)(wei)發(fa)射正脈(mo)沖上(shang)(shang)升沿和(he)基線(xian)交點(dian)(dian)(dian)的(de)終(zhong)端設備(bei)開路(lu)(lu)電(dian)(dian)(dian)(dian)纜(lan)(lan)，用(yong)反(fan)射正脈(mo)沖上(shang)(shang)升沿和(he)基線(xian)交點(dian)(dian)(dian)確定光(guang)標終(zhong)點(dian)(dian)(dian)。
