電(dian)纜故(gu)障測(ce)試儀-高壓開關(斷路器)機械特性(xing)測(ce)試儀-專(zhuan)注于電(dian)力(li)試驗設備研發! 咨詢電(dian)話:130-3714-0838
LD-2003電纜故障定點儀用于埋地電絕緣故障點的快(kuai)速(su)、精確(que)定(ding)位及電纜埋設路(lu)徑和埋設深(shen)度(du)的準確(que)探(tan)測。
LD-2003電纜(lan)故(gu)障(zhang)定點(dian)(dian)儀主要(yao)特點(dian)(dian):
1、用特(te)殊(shu)結構(gou)的聲波振動(dong)傳感器(qi)及低噪聲專用器(qi)件作前置放大(da)(da),大(da)(da)大(da)(da)提高了儀器(qi)定點(dian)(dian)和路徑探測的靈敏度。在(zai)信號處理技(ji)術上(shang),用數(shu)字顯(xian)示故障點(dian)(dian)與傳感探頭間(jian)的距離,極大(da)(da)地消除了定點(dian)(dian)時(shi)的盲目性。
2、電(dian)纜(lan)(lan)溝內架空的(de)故(gu)障(zhang)電(dian)纜(lan)(lan),過去(qu)定點時,全(quan)電(dian)纜(lan)(lan)的(de)振動聲使任何(he)定點儀(yi)束(shu)手無(wu)策,無(wu)法判定封閉性故(gu)障(zhang)的(de)具體(ti)位置(zhi)。如(ru)今,只(zhi)要(yao)將本儀(yi)器傳感器探頭接觸故(gu)障(zhang)電(dian)纜(lan)(lan)或(huo)近旁(pang)的(de)電(dian)纜(lan)(lan)上(shang),便可(ke)精確顯示故(gu)障(zhang)距離及(ji)方向(xiang),毫(hao)不費力(li)地快速確定故(gu)障(zhang)位置(zhi)。
3、工(gong)(gong)頻(pin)自適應對消理論及(ji)高工(gong)(gong)頻(pin)陷波(bo)技(ji)術,大大加強了(le)在(zai)強工(gong)(gong)頻(pin)電(dian)(dian)場(chang)環境(jing)中對50Hz工(gong)(gong)頻(pin)信號的抑制(zhi)及(ji)抗干擾能力,縮小(xiao)了(le)定(ding)點(dian)盲區。在(zai)儀器功能上,利(li)用聲電(dian)(dian)同(tong)步接收顯示技(ji)術,有效地(di)克服了(le)定(ding)點(dian)現場(chang)環境(jing)噪音干擾造(zao)成的定(ding)點(dian)困難問題。尤(you)其是故障距離的數(shu)字(zi)顯示省去了(le)操作員(yuan)對復雜波(bo)形的分析判(pan)斷,在(zai)相當程度上替代了(le)閃測(ce)(ce)儀的粗測(ce)(ce)距離功能。對于數(shu)百(bai)米長的故障電(dian)(dian)纜,一般不用粗測(ce)(ce)便可實(shi)施定(ding)點(dian),真正(zheng)實(shi)現了(le)高效、快速、準(zhun)確。利(li)用15kHz幅度調制(zhi)電(dian)(dian)磁波(bo)和幅度檢波(bo)技(ji)術作路徑(jing)探測(ce)(ce)和電(dian)(dian)纜埋設深度測(ce)(ce)定(ding),避免了(le)原等(deng)幅15kHz信號源(yuan)時(shi)電(dian)(dian)視機行(xing)頻(pin)對定(ding)點(dian)儀的干擾。
4、操作極其簡便,打開電源開關即可,無須換擋和功(gong)能選(xuan)擇。結構緊湊、小(xiao)巧(qiao)、模(mo)塊(kuai)化,便于攜帶維修,功(gong)能強大。
