絕緣電阻測量儀主要用于測量大型變壓器、互感器、發(fā)電機(jī)、高壓電動機(jī)、電力電容、電力電纜、避雷器等設(shè)備的絕緣電阻。 </p> <p> 絕緣電阻測量儀英文：Insulation Resistance Tester用來將其他儀器的絕緣性以電阻的形式測量出來的儀器。因為大部分生活中的絕緣體并非完美絕緣，因此儀器可以通過將高壓直流電應(yīng)用到絕緣體上的方法，測量電流并計算電阻。使用電壓一般為250~1000V，合格的絕緣體電阻一般高于2 Mega Ohm(次) </p> <p>

校準(zhǔn)這些儀器時的一個主要問題是找到合適的電阻器，當(dāng)然是首先要足夠精確；還需要電阻值足夠大，使其能夠承受高直流電壓。此外，對于應(yīng)該采用什么樣的電阻值來進(jìn)行校準(zhǔn)，兆歐表制造商并沒有統(tǒng)一的標(biāo)準(zhǔn)，所以就需要各種各樣的電阻值。通過了解各種不同的絕緣測試儀，可以知道它們需要不同的性能檢查點(diǎn)。例如，某個測試儀需要測試50kΩ，而另一款測試儀則需要測試60kΩ，再一款又需要測試100 kΩ，等等。 </p> <p> “通用”的多功能電氣/電子校準(zhǔn)器不能用于校準(zhǔn)絕緣電阻測試儀，因為它們的電阻器通常**能夠處理有限的電壓，常常比較高不過20V。絕緣電阻校準(zhǔn)器所面臨的挑戰(zhàn)是將這些特殊需要集成到一款經(jīng)濟(jì)、緊湊和便攜的解決方案中。云南電纜絕緣電阻測試儀哪種好</p><p>
