意聯電氣專業生產電纜故障測試儀,產品(pin)型號(hao)豐富,價(jia)格合理,專業電(dian)測(ce)(ce)10年,找電(dian)纜故障(zhang)測(ce)(ce)試儀(yi),選意聯電(dian)氣,打造電(dian)測(ce)(ce)精品(pin)。
為了(le)能更好、更精(jing)準的查找(zhao)故(gu)障(zhang)(zhang)點(dian)(dian),QK8600電纜故(gu)障(zhang)(zhang)測(ce)試儀(yi),也稱探(tan)(tan)(tan)測(ce)儀(yi);在探(tan)(tan)(tan)測(ce)到(dao)故(gu)障(zhang)(zhang)點(dian)(dian)時,探(tan)(tan)(tan)測(ce)人(ren)員的雙腳要(yao)盡(jin)量拉開距離。以減(jian)小(xiao)接地(di)點(dian)(dian)的面積再探(tan)(tan)(tan)測(ce)一段時間后,如發現指示燈亮度(du)不夠時,一定要(yao)充(chong)電后再進(jin)行探(tan)(tan)(tan)測(ce)。
如(ru)地(di)埋線漏電故障點(dian)太多(duo)或對地(di)埋線不能供電時,可用(yong)B型機進行(xing)探測。用(yong)B型機進行(xing)探測時,應首先把(ba)要測的線路與高壓連線全部斷開。
然后把大功率信號發射器的紅(hong)色接(jie)線(xian)柱,接(jie)在(zai)地(di)埋(mai)線(xian)其(qi)中一(yi)根(gen)或多根(gen)線(xian)上(shang),黑色接(jie)線(xian)柱接(jie)上(shang)連(lian)線(xian),用長約(yue)5-15公(gong)分(fen)的鐵(tie)釘釘在(zai)地(di)上(shang)(好把接(jie)地(di)的地(di)方用水(shui)灑濕),然后按以上(shang)步驟,就可進行探測。
另(ling)外,使用電纜故(gu)障測(ce)試儀時,首先(xian)在探測(ce)之(zhi)前,要弄清漏電故(gu)障線(xian)的性質,向(xiang)線(xian)路(lu)送(song)電。如(ru)果只是絕緣損壞(huai)向(xiang)大地(di)漏電,線(xian)路(lu)不短路(lu),不斷(duan)線(xian)時,可用常規向(xiang)線(xian)路(lu)送(song)電;
如(ru)果線(xian)(xian)(xian)間短(duan)路且(qie)漏電(dian)或線(xian)(xian)(xian)間絕緣正常,有部分(fen)斷線(xian)(xian)(xian)且(qie)漏電(dian)時,可將本路所有的(de)線(xian)(xian)(xian)(三線(xian)(xian)(xian)或四線(xian)(xian)(xian))并接在一起(qi),向線(xian)(xian)(xian)路單(dan)相送(song)電(dian);
如果對地絕緣良好,內芯(xin)斷(duan)線(xian)故(gu)障(zhang)時,可將(jiang)所(suo)有好線(xian)及(ji)斷(duan)芯(xin)故(gu)障(zhang)線(xian)的一(yi)(yi)端(duan)一(yi)(yi)并接(jie)地,由故(gu)障(zhang)線(xian)的另一(yi)(yi)端(duan)向故(gu)障(zhang)線(xian)送(song)單(dan)相電源。
本儀器(qi)(qi)需(xu)一人操作。將電纜故障測(ce)試儀的(de)(de)(de)耳(er)機插(cha)頭插(cha)入儀器(qi)(qi)耳(er)機孔,按下開關(guan),指示(shi)燈亮。將探(tan)(tan)測(ce)板(ban)上的(de)(de)(de)連線(xian)分(fen)(fen)別接(jie)在紅黑接(jie)線(xian)柱上,然(ran)(ran)后把(ba)探(tan)(tan)測(ce)板(ban)相碰幾下,同時耳(er)機內應聽(ting)到咯叭(ba)聲,機器(qi)(qi)屬正常。把(ba)帶釘的(de)(de)(de)探(tan)(tan)測(ce)板(ban)分(fen)(fen)別扣在探(tan)(tan)測(ce)員的(de)(de)(de)左右腳上,做為(wei)探(tan)(tan)測(ce)器(qi)(qi)的(de)(de)(de)兩個(ge)接(jie)地點,然(ran)(ran)后就可(ke)以(yi)對地埋線(xian)進行(xing)探(tan)(tan)測(ce)。
在地(di)埋(mai)線(xian)上方從線(xian)路(lu)的(de)一端向另一端探測(ce),緩(huan)慢向前行走(zou),在對地(di)絕緣良好的(de)線(xian)段,耳(er)機(ji)基本無聲(sheng)(sheng),在臨近故障(zhang)點(dian)(dian)(C)時(shi),聲(sheng)(sheng)音(yin)逐漸由(you)小到大(da),到故障(zhang)點(dian)(dian)(A)時(shi),聲(sheng)(sheng)音(yin)大(da),當越過故障(zhang)點(dian)(dian)到(B)時(shi),聲(sheng)(sheng)音(yin)則由(you)大(da)變小至(zhi)無聲(sheng)(sheng),然后(hou)可退(tui)回到聲(sheng)(sheng)音(yin)zui大(da)時(shi)的(de)地(di)方(A),此點(dian)(dian)即為漏電故障(zhang)點(dian)(dian)。
