GSB-94A高壓直流數字(zi)電壓表   0～10kV  

一、概述

GSB-94高壓(ya)(ya)直流(liu)(liu)數(shu)(shu)字電(dian)(dian)(dian)(dian)壓(ya)(ya)表(biao)采(cai)用先進的(de)(de)(de)(de)集成電(dian)(dian)(dian)(dian)路(lu)技術和直流(liu)(liu)高壓(ya)(ya)分(fen)壓(ya)(ya)技術生產的(de)(de)(de)(de)直流(liu)(liu)高電(dian)(dian)(dian)(dian)壓(ya)(ya)測(ce)(ce)量(liang)(liang)(liang)儀(yi)(yi)表(biao)。它輸入電(dian)(dian)(dian)(dian)阻高（10GΩ），測(ce)(ce)量(liang)(liang)(liang)速度快，過載能力(li)強，準確度高，重量(liang)(liang)(liang)輕(qing)，攜帶方便。本儀(yi)(yi)表(biao)是(shi)測(ce)(ce)量(liang)(liang)(liang)直流(liu)(liu)高電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)(de)理想儀(yi)(yi)表(biao)。兆(zhao)歐(ou)表(biao)的(de)(de)(de)(de)工作(zuo)電(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)直流(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)，以往(wang)采(cai)用靜(jing)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)(ya)表(biao)來測(ce)(ce)量(liang)(liang)(liang)，但靜(jing)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)(ya)表(biao)是(shi)測(ce)(ce)量(liang)(liang)(liang)有(you)效值的(de)(de)(de)(de)儀(yi)(yi)表(biao)，即使兆(zhao)歐(ou)表(biao)的(de)(de)(de)(de)整流(liu)(liu)電(dian)(dian)(dian)(dian)路(lu)損壞的(de)(de)(de)(de)情況下，靜(jing)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)(ya)表(biao)仍有(you)讀數(shu)(shu)顯示。高壓(ya)(ya)直流(liu)(liu)數(shu)(shu)字電(dian)(dian)(dian)(dian)壓(ya)(ya)表(biao)正逐漸(jian)替代靜(jing)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)(ya)表(biao)來測(ce)(ce)量(liang)(liang)(liang)兆(zhao)歐(ou)表(biao)的(de)(de)(de)(de)開路(lu)電(dian)(dian)(dian)(dian)壓(ya)(ya)和中值電(dian)(dian)(dian)(dian)壓(ya)(ya)等。它將是(shi)未來的(de)(de)(de)(de)兆(zhao)歐(ou)表(biao)檢定規(gui)程中規(gui)定的(de)(de)(de)(de)測(ce)(ce)量(liang)(liang)(liang)直流(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)(de)儀(yi)(yi)表(biao)。
