27I智能絕緣電阻測試儀是我公司研制開發(fā)的、具有完全自主的知識(shí)產(chǎn)權(quán)，產(chǎn)品完全滿足DL/T845.1-2004標(biāo)準(zhǔn)要求。對(duì)電力設(shè)備的絕緣性能進(jìn)行評(píng)估時(shí)，不*要測量其絕緣電阻值，更重要的是要做吸收比和極化指數(shù)的試驗(yàn)，從而為下一步的泄漏，介質(zhì)損耗，局部放電等絕緣性能試驗(yàn)提供安全保障。 </p> <p> <br /> </p> <p> 二、產(chǎn)品特性： </p> <p> METRAHIT 27I智能絕緣電阻測試儀高壓電源部分采用模塊化設(shè)計(jì)，輸出電流大，輸出電壓穩(wěn)定，采樣電路采用檢流計(jì)比較法**高性能數(shù)字元器件，算法更加科學(xué)，即便在測試電壓發(fā)生變化時(shí)，測量結(jié)果依然正確。儀器采用微電腦控制流程，界面更具人性化，并設(shè)有欠壓提示和過壓保護(hù)，測試時(shí)間自動(dòng)顯示。內(nèi)附高性能鋰電池，為使用人員提供極大的方便，是同類儀器中的佳選擇。 </p> <p> <br /> </p><p style="text-indent:25px">有的標(biāo)準(zhǔn)規(guī)定每kV電壓，絕緣電阻不小于1MΩ等。在家用電器產(chǎn)品標(biāo)準(zhǔn)中，通常只規(guī)定熱態(tài)絕緣電阻，而不規(guī)定常態(tài)條件下的絕緣電阻值，常態(tài)條件下的絕緣電阻值由企業(yè)標(biāo)準(zhǔn)中自行制定。如果常態(tài)絕緣電阻值低，說明絕緣結(jié)構(gòu)中可能存在某種隱患或受損。如電機(jī)繞組對(duì)外殼的絕緣電阻低，可能是在嵌線時(shí)繞組的均線槽絕緣受到損傷所致。在使用電器時(shí)，由于突然上電或切斷電源或其它緣故，電路產(chǎn)生過電壓，在絕緣受損處產(chǎn)生擊穿，造成對(duì)人身的安全或威脅

500伏以下的電氣設(shè)備選用500~1000伏的兆歐表；瓷瓶、母線、刀閘應(yīng)選用2500伏以上的兆歐表。數(shù)字兆歐表測量范圍的選擇原則是：要使測量范圍適應(yīng)被測絕緣電阻的數(shù)值免讀數(shù)時(shí)產(chǎn)生較大的誤差。如有些兆歐表的讀數(shù)不是從零開始，而是從1兆歐或2兆歐開始。這種表就不適宜用于測定處在潮濕環(huán)境中的低壓電氣設(shè)備的絕緣電阻。因?yàn)檫@種設(shè)備的絕緣電阻有有可能小于1兆歐，使儀表得不到讀數(shù)，容易誤認(rèn)為絕緣電阻為零，而得出錯(cuò)誤結(jié)論
