開關回路電阻測量儀

簡介  

斷路(lu)(lu)(lu)器（以下簡稱開關）導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)回(hui)(hui)(hui)(hui)路(lu)(lu)(lu)的(de)(de)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)能的(de)(de)好(hao)壞，對(dui)保障(zhang)開關的(de)(de)安全運(yun)行具有(you)重要(yao)(yao)作(zuo)用(yong)(yong)。導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)能的(de)(de)優劣可以通過導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)回(hui)(hui)(hui)(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)(de)大小反映(ying)出來。因此IEC標準及制(zhi)造廠都規定(ding)(ding)應測量回(hui)(hui)(hui)(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)，并(bing)且對(dui)各(ge)種(zhong)形式的(de)(de)開關的(de)(de)回(hui)(hui)(hui)(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)有(you)明(ming)確(que)規定(ding)(ding)指標。一般(ban)過去(qu)使用(yong)(yong)雙臂電(dian)(dian)(dian)(dian)(dian)(dian)(dian)橋(qiao)。由(you)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)橋(qiao)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)都比較小，當(dang)開關的(de)(de)動(dong)靜觸頭之間(jian)有(you)雜質或(huo)表面有(you)氧化等(deng)，測試的(de)(de)數據分散性(xing)就較大。同時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)橋(qiao)的(de)(de)抗干擾性(xing)差。因此再GB50150-91和(he)DL/T596-1996中都有(you)規定(ding)(ding)“用(yong)(yong)直流(liu)壓強法(fa)"， “電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)不小于(yu)100安"。本(ben)款儀器是我公司為適應規程(cheng)要(yao)(yao)求，廣泛(fan)適用(yong)(yong)于(yu)各(ge)種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器開關的(de)(de)接觸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)、回(hui)(hui)(hui)(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線、焊縫(feng)接觸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)(de)測量。
