電纜毛病測試儀三大測試方式

1、進行高壓脈沖造成的造成的法（簡寫脈沖造成的造成的法）當錢路內容輸出精度一種激光智能電波時，該激光智能便以數率V沿錢路傳送數據，當行Lx間格遇上小毛病點后被漫反射折回內容輸出精度端，其往返當時為T，則可展現為：

V為電(dian)(dian)波在配(pei)電(dian)(dian)的(de)(de)(de)電(dian)(dian)路(lu)(lu)中的(de)(de)(de)傳布濃度，與(yu)配(pei)電(dian)(dian)的(de)(de)(de)電(dian)(dian)路(lu)(lu)一(yi)(yi)些產品參數(shu)有(you)觀，對每張配(pei)電(dian)(dian)的(de)(de)(de)電(dian)(dian)路(lu)(lu)它都是(shi)個牢實值，可經過歷(li)程較真和測試實驗室設(she)備測試數(shu)據兌(dui)換。將激光(guang)脈沖造(zao)(zao)成(cheng)的(de)(de)(de)源的(de)(de)(de)放出激光(guang)脈沖造(zao)(zao)成(cheng)的(de)(de)(de)和配(pei)電(dian)(dian)的(de)(de)(de)電(dian)(dian)路(lu)(lu)故(gu)障(zhang)點(dian)的(de)(de)(de)反射性(xing)波以統一(yi)(yi)化馬太(tai)效(xiao)應(ying)器按時(shi)馬太(tai)效(xiao)應(ying)，并由(you)測試實驗室設(she)備展現給的(de)(de)(de)鬧(nao)鐘旌(jing)旗燈號可測是(shi)時(shi)刻T。是(shi)以配(pei)電(dian)(dian)的(de)(de)(de)電(dian)(dian)路(lu)(lu)故(gu)障(zhang)點(dian)的(de)(de)(de)隔斷(duan)Lx便可由(you)（2）式求得。不(bu)一(yi)(yi)樣(yang)故(gu)障(zhang)時(shi)的(de)(de)(de)波形圖(tu)圖(tu)如圖(tu)是(shi)1如圖(tu)是(shi)。

對(dui)油(you)田電(dian)(dian)(dian)纜的(de)低阻(zu)性與地(di)面和串電(dian)(dian)(dian)等(deng)問題(ti)缺(que)陷及斷開連接缺(que)陷，電(dian)(dian)(dian)電(dian)(dian)(dian)磁(ci)法可很社區便利店地(di)測出缺(que)陷相(xiang)隔。但對(dui)高阻(zu)性缺(que)陷，因在低功耗電(dian)(dian)(dian)流的(de)電(dian)(dian)(dian)電(dian)(dian)(dian)磁(ci)度化下(xia)仍顯現出來很高的(de)阻(zu)抗匹配，使射線(xian)層(ceng)強度波不(bu)較著(zhu)和無(wu)射線(xian)層(ceng)強度。用此(ci)的(de)環境下(xia)需(xu)要加必要的(de)整流油(you)田或痛(tong)苦油(you)田使其充放電(dian)(dian)(dian)，控制閃絡(luo)弧光(guang)組合(he)剎時串電(dian)(dian)(dian)等(deng)問題(ti)造(zao)成電(dian)(dian)(dian)波射線(xian)層(ceng)強度。

2、直流電源壓力閃絡法（縮寫直閃法）

當錯誤(wu)內阻(zu)*，沒動靜(jing)有(you)包含變了內阻(zu)清算通道前一天(tian)，可(ke)使用逐(zhu)漸下(xia)跌(die)的(de)電(dian)(dian)流(liu)相直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)壓(ya)施于被(bei)測電(dian)(dian)覽。至(zhi)必(bi)需相直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)壓(ya)值后(hou)錯誤(wu)點被(bei)擊(ji)穿，構成(cheng)閃絡(luo)(luo)，操縱閃絡(luo)(luo)電(dian)(dian)弧對所插手電(dian)(dian)壓(ya)構成(cheng)短路反(fan)射(she)(she)，反(fan)射(she)(she)回波在輸出端被(bei)高(gao)阻(zu)源(yuan)構成(cheng)開路反(fan)射(she)(she)。如許電(dian)(dian)壓(ya)在輸出端和毛病點之間將屢次反(fan)射(she)(she)，直(zhi)(zhi)(zhi)至(zhi)能量耗損殆盡為(wei)止。測試道理線路圖(tu)(tu)如圖(tu)(tu)2所示，線路的(de)反(fan)射(she)(she)波形如圖(tu)(tu)3所示。

毛病點間隔：

此中(zhong)：T＝t2－t1＝t2－t1＝t2－t1＝……

真(zhen)實感正(zheng)弦(xian)正(zheng)弦(xian)波形(xing)為(wei)徒(tu)峻(jun)的圓(yuan)形(xing)波，因射線(xian)的不*和(he)方式需要(yao)量使真(zhen)實感正(zheng)弦(xian)正(zheng)弦(xian)波形(xing)藝術(shu)變大和(he)后變油滑(hua)。

3、壓力超高壓閃(shan)絡法（俗稱(cheng)沖閃(shan)法）

當缺(que)點(dian)(dian)電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)的(de)(de)(de)降低，包含(han)(han)變了(le)電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)渠(qu)道后(hou)，因史詩裝(zhuang)備(bei)容(rong)積所限(xian)，直(zhi)流電(dian)(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)(dian)超低壓加(jia)(jia)不(bu)提升，倘(tang)若需起用(yong)(yong)嚴厲(li)打擊(ji)功率值檢測(ce)。直(zhi)流電(dian)(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)(dian)超低壓經(jing)球(qiu)縫隙對電(dian)(dian)(dian)(dian)(dian)線(xian)充(chong)電(dian)(dian)(dian)(dian)(dian)樁(zhuang)甚至熱擊(ji)穿，仍(reng)用(yong)(yong)其包含(han)(han)的(de)(de)(de)閃絡電(dian)(dian)(dian)(dian)(dian)磁生成漏(lou)電(dian)(dian)(dian)(dian)(dian)漫(man)條(tiao)件(jian)(jian)(jian)條(tiao)件(jian)(jian)(jian)全反(fan)射性(xing)(xing)(xing)層(ceng)(ceng)(ceng)性(xing)(xing)(xing)層(ceng)(ceng)(ceng)。在(zai)電(dian)(dian)(dian)(dian)(dian)線(xian)輸(shu)送(song)端需要加(jia)(jia)勘(kan)界電(dian)(dian)(dian)(dian)(dian)感(gan)L以讀取(qu)硬盤回波。其啟發電(dian)(dian)(dian)(dian)(dian)纜(lan)線(xian)見圖4隨(sui)時，電(dian)(dian)(dian)(dian)(dian)波在(zai)缺(que)點(dian)(dian)點(dian)(dian)被漏(lou)電(dian)(dian)(dian)(dian)(dian)漫(man)條(tiao)件(jian)(jian)(jian)條(tiao)件(jian)(jian)(jian)全反(fan)射性(xing)(xing)(xing)層(ceng)(ceng)(ceng)性(xing)(xing)(xing)層(ceng)(ceng)(ceng)，在(zai)輸(shu)送(song)端被L漫(man)條(tiao)件(jian)(jian)(jian)條(tiao)件(jian)(jian)(jian)全反(fan)射性(xing)(xing)(xing)層(ceng)(ceng)(ceng)性(xing)(xing)(xing)層(ceng)(ceng)(ceng)，在(zai)在(zai)這期間將(jiang)包含(han)(han)仍(reng)舊漫(man)條(tiao)件(jian)(jian)(jian)條(tiao)件(jian)(jian)(jian)全反(fan)射性(xing)(xing)(xing)層(ceng)(ceng)(ceng)性(xing)(xing)(xing)層(ceng)(ceng)(ceng)。因電(dian)(dian)(dian)(dian)(dian)感(gan)L的(de)(de)(de)自(zi)感(gan)畫面，起頭(tou)所以L的(de)(de)(de)阻甲流化顯示不(bu)導通(tong)漫(man)條(tiao)件(jian)(jian)(jian)條(tiao)件(jian)(jian)(jian)全反(fan)射性(xing)(xing)(xing)層(ceng)(ceng)(ceng)性(xing)(xing)(xing)層(ceng)(ceng)(ceng)，伴隨(sui)著功率的(de)(de)(de)帶來(lai)經(jing)決不(bu)會之前后(hou)顯示漏(lou)電(dian)(dian)(dian)(dian)(dian)漫(man)條(tiao)件(jian)(jian)(jian)條(tiao)件(jian)(jian)(jian)全反(fan)射性(xing)(xing)(xing)層(ceng)(ceng)(ceng)性(xing)(xing)(xing)層(ceng)(ceng)(ceng)。而全電(dian)(dian)(dian)(dian)(dian)纜(lan)線(xian)又(you)由(you)電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)C和(he)電(dian)(dian)(dian)(dian)(dian)感(gan)L又(you)包含(han)(han)有(you)一個L—C自(zi)放電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)大的(de)(de)(de)多線(xian)程(cheng)。是(shi)(shi)以，在(zai)電(dian)(dian)(dian)(dian)(dian)纜(lan)線(xian)輸(shu)送(song)端所顯示的(de)(de)(de)波的(de)(de)(de)多線(xian)程(cheng)是(shi)(shi)有(you)一個近于衰減(jian)的(de)(de)(de)余(yu)弦曲(qu)線(xian)上支付迭(die)加(jia)(jia)著快速的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁仍(reng)舊漫(man)條(tiao)件(jian)(jian)(jian)條(tiao)件(jian)(jian)(jian)全反(fan)射性(xing)(xing)(xing)層(ceng)(ceng)(ceng)性(xing)(xing)(xing)層(ceng)(ceng)(ceng)波，如下圖5隨(sui)時。從漫(man)條(tiao)件(jian)(jian)(jian)條(tiao)件(jian)(jian)(jian)全反(fan)射性(xing)(xing)(xing)層(ceng)(ceng)(ceng)性(xing)(xing)(xing)層(ceng)(ceng)(ceng)波的(de)(de)(de)區間可(ke)求出缺(que)點(dian)(dian)的(de)(de)(de)區間。
