AR3123 高壓兆歐表

產(chan)品特點

絕緣電(dian)(dian)(dian)阻(zu)(zu)測試儀(yi)，通(tong)常被稱為兆歐表或(huo)高阻(zu)(zu)計，廣泛用于(yu)測量發(fa)電(dian)(dian)(dian)機(ji)、馬達、電(dian)(dian)(dian)源(yuan)變(bian)壓器、配線、電(dian)(dian)(dian)器和其它(ta)電(dian)(dian)(dian)氣裝置（如(ru)控制、信號、通(tong)信和電(dian)(dian)(dian)源(yuan)的電(dian)(dian)(dian)纜(lan)）的絕緣 電(dian)(dian)(dian)阻(zu)(zu)。它(ta)們往(wang)(wang)往(wang)(wang)被用于(yu)例行(xing)維護程序中來指示電(dian)(dian)(dian)機(ji)在數(shu)月或(huo)數(shu)年內絕緣電(dian)(dian)(dian)阻(zu)(zu)的變(bian)化(hua)。絕緣電(dian)(dian)(dian)阻(zu)(zu)發(fa)生大的變(bian)化(hua)，就(jiu)可能預示著潛在的故障。所以，就(jiu)需要對兆歐表進行(xing) 定(ding)期校準，以確保儀(yi)表本身沒有隨時(shi)間(jian)發(fa)生變(bian)化(hua)。
