一、產品概(gai)述

KTHLC-200A回路電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)試(shi)(shi)儀按新電(dian)(dian)(dian)(dian)力(li)設備預防性試(shi)(shi)驗規(gui)程(cheng)要求，各種(zhong)開(kai)(kai)(kai)關設備的導電(dian)(dian)(dian)(dian)回路電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)試(shi)(shi)是(shi)必測(ce)(ce)項目，其(qi)測(ce)(ce)試(shi)(shi)電(dian)(dian)(dian)(dian)流不(bu)得小于100A，連續電(dian)(dian)(dian)(dian)流時間不(bu)得少(shao)于一(yi)(yi)分鐘。對此，我(wo)公司設計開(kai)(kai)(kai)發出新一(yi)(yi)代回路電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)試(shi)(shi)儀系列產品，其(qi)適用(yong)(yong)(yong)于測(ce)(ce)試(shi)(shi)高(gao)低壓開(kai)(kai)(kai)關的主觸(chu)頭(tou)接觸(chu)電(dian)(dian)(dian)(dian)阻(zu)值(zhi)(zhi)，高(gao)低壓電(dian)(dian)(dian)(dian)纜線路的直流電(dian)(dian)(dian)(dian)阻(zu)值(zhi)(zhi)等。100A回路電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)試(shi)(shi)儀是(shi)采(cai)用(yong)(yong)(yong)100A恒流輸出，可采(cai)用(yong)(yong)(yong)截面較細(xi)的測(ce)(ce)試(shi)(shi)線，減輕了現場測(ce)(ce)試(shi)(shi)人員的勞動(dong)強度(du)。測(ce)(ce)試(shi)(shi)數據用(yong)(yong)(yong)帶背光(guang)的點陣式液(ye)晶顯示，適用(yong)(yong)(yong)于不(bu)同的工作環(huan)境。
