絕緣測(cè)試儀，通常被稱為數(shù)字兆歐表或高阻計(jì)，***用于測(cè)量發(fā)電機(jī)、馬達(dá)、電源變壓器、配線、電器和其它電氣裝置（如控制、信號(hào)、通信和電源的電纜）的絕緣電阻。它們往往被用于例行維護(hù)程序中來(lái)指示電機(jī)在數(shù)月或數(shù)年內(nèi)絕緣電阻的變化。絕緣電阻發(fā)生大的變化，就可能預(yù)示著潛在的故障。所以，就需要對(duì)兆歐表進(jìn)行定期校準(zhǔn)，以確保儀表本身沒(méi)有隨時(shí)間發(fā)生變化。

兆歐表通過(guò)用一個(gè)電壓激勵(lì)被測(cè)裝置或網(wǎng)絡(luò)，然后測(cè)量激勵(lì)所產(chǎn)生的電流，利用歐姆定律測(cè)量出電阻。優(yōu)良的兆歐表校準(zhǔn)器包括各種可選的電阻器，這點(diǎn)與現(xiàn)代校準(zhǔn)器利用合成電阻功能提供的電阻器差別不大。兆歐表校準(zhǔn)器與直流/低頻校準(zhǔn)器的不同之處在于所需的電阻器范圍，以及耐受的電壓能力不同。例如，與數(shù)字多用表（DMM）上配備的歐姆表功能相比，這些電氣測(cè)試器在進(jìn)行電阻測(cè)量時(shí)施加的電壓要高得多，廣西高美絕緣電阻測(cè)試儀。兆歐表采用的電壓范圍通常從50V到高達(dá)5 kV；而典型數(shù)字多用表的電壓一般小于10 V。對(duì)于絕緣測(cè)試來(lái)說(shuō)，需要測(cè)量的電阻值范圍很大，廣西高美絕緣電阻測(cè)試儀，其上限可達(dá)到10TΩ，廣西高美絕緣電阻測(cè)試儀，所需的電壓更高。 10kv絕緣電阻測(cè)試儀報(bào)價(jià)是多少_深圳茂迪。廣西高美絕緣電阻測(cè)試儀</p><div

絕緣電阻表一般采用自動(dòng)校準(zhǔn)技術(shù)，除指明可以更換的部件外，所以不要隨意更換，以免技術(shù)指標(biāo)發(fā)生偏差。一、一般的維修保養(yǎng) 1)定期用濕布及中性的清潔劑清理儀表的外殼，不要用研磨劑或溶劑。端子上和表筆端子上污垢會(huì)影響讀數(shù)，可用清潔劑清理每個(gè)端子上的污物。 2)不使用時(shí)，按power鍵關(guān)閉，長(zhǎng)期用應(yīng)取出電池。 3)存放儀表應(yīng)避免潮濕，高溫和強(qiáng)磁場(chǎng)。二、更換電池 1)按power鍵關(guān)閉電源，并從端子上把表筆或測(cè)試導(dǎo)線拆下，使測(cè)試導(dǎo)線與被測(cè)電路完全斷開(kāi)。 2)將電池蓋的兩顆螺絲拆下，并把電池蓋取下。 3)從電池盒上把電池取下。 4)用6節(jié)aa(am3/lr6)新電池(標(biāo)準(zhǔn)容量約2450mah)換上。 5)把電池蓋合上，裝上兩顆螺絲。絕緣電阻測(cè)試儀-高壓-水內(nèi)冷發(fā)電機(jī)絕緣電阻測(cè)試儀。廣西高美絕緣電阻測(cè)試儀</p><p
