怎樣選用數(shù)字兆歐表？兆歐表的選用，主要是選擇其電壓及測(cè)量范圍，高壓電氣設(shè)備需使用電壓高的兆歐表。低壓電氣設(shè)備需使用電壓低的兆歐表。一般選擇原則是： 500伏以下的電氣設(shè)備選用500~1000伏的兆歐表；瓷瓶、母線，河北絕緣電阻測(cè)試儀 mi2124價(jià)格、刀閘應(yīng)選用2500伏以上的兆歐表。數(shù)字兆歐表測(cè)量范圍的選擇原則是：要使測(cè)量范圍適應(yīng)被測(cè)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(cè)定處在潮濕環(huán)境中的低壓電氣設(shè)備的絕緣電阻，河北絕緣電阻測(cè)試儀 mi2124價(jià)格，河北絕緣電阻測(cè)試儀 mi2124價(jià)格。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 . </p> <p> <br /> 數(shù)字絕緣電阻表測(cè)試儀-接地電阻儀器型號(hào)。河北絕緣電阻測(cè)試儀

style="text-indent:25px">7、電阻量程選擇把“電阻量程”開關(guān)選向需要的量程或從MΩ檔向2000GΩ量程步進(jìn)，若儀表連續(xù)報(bào)警，則表示被測(cè)電阻太低，應(yīng)退低檔來測(cè)量。 8、電阻值讀數(shù) 通過“MΩ/GΩ”表讀取電阻值。秒表在高壓輸出后的15秒、60秒、每隔60秒報(bào)時(shí)，便于操作者記錄。關(guān)于吸收比、極化指數(shù)的計(jì)算公式為：吸收比=R60s/R15s，即第60秒的電阻讀數(shù)÷第15秒的電阻讀數(shù)。極化指數(shù)=R10min/R1min，即第10分鐘的電阻讀數(shù)÷第1分鐘的電阻讀數(shù)。 9、測(cè)試電壓退出將“高壓控制”按鈕退出，這時(shí)“kV”表就會(huì)緩慢回零，數(shù)字秒表也會(huì)退出顯示。如果“kV”表不緩慢回零，則應(yīng)以帶電阻的放***放電。 10、結(jié)束當(dāng)“kV”表顯示為0.00kV后，再經(jīng)過對(duì)被測(cè)物人工放***接通大地，證明安全后即可關(guān)機(jī)、拆線。測(cè)試結(jié)束。海南高壓絕緣電阻測(cè)試儀多少錢一個(gè)數(shù)字絕緣電阻測(cè)試儀的使用方法。</p><div style="width:100%;text-align:

3、無法搖動(dòng)，即發(fā)電機(jī)有卡住現(xiàn)象或者搖動(dòng)時(shí)很費(fèi)力。主要原因有兩類：*是發(fā)電機(jī)轉(zhuǎn)子與極靴相碰或者是增速齒輪嚙合不好，第二是發(fā)電機(jī)轉(zhuǎn)子已損壞。 4、機(jī)殼漏電。大致原因應(yīng)該是內(nèi)部引線碰殼或發(fā)電機(jī)彈簧引出線碰殼或是由于受潮造成絕緣不良。用數(shù)字兆歐表測(cè)量絕緣時(shí)，為什么規(guī)定搖測(cè)時(shí)間為１分鐘？用兆歐表測(cè)量絕緣電阻時(shí)，一般規(guī)定以搖測(cè)一分鐘后的讀數(shù)為準(zhǔn)備。因?yàn)樵诮^緣體上加上直流電壓后，流過絕緣體的電流（吸收電流）將隨時(shí)間的增長(zhǎng)而逐漸下降。而絕緣的直流電阻率是根據(jù)穩(wěn)態(tài)傳導(dǎo)電流確定的，并且不同材料的絕緣體，其絕緣吸收電流的衰減時(shí)間也不同。但是試驗(yàn)證明，絕大多數(shù)材料其絕緣吸收電流經(jīng)過一分鐘已趨于穩(wěn)定，所以規(guī)定以加壓一分鐘后的絕緣電阻值來確定絕緣性能的好壞。德國(guó)進(jìn)口絕緣電阻測(cè)試儀器怎么樣？</p><div
