合成電阻的方法由于受到設(shè)計成本和尺寸規(guī)格的限制被排除在外。采用的是分立式高壓電阻器矩陣的方法，組成一個陣列，能夠提供500,000多種電阻值輸出。在這種校準器中，有8個范圍的電阻值，覆蓋了10kΩ到10 GΩ的范圍，每個范圍均能提供4.5 位的穩(wěn)定輸出。 </p> <p> 收**適的高壓電阻器并將其集成到一個儀器內(nèi)又存在另一項挑戰(zhàn)。這就是與歐盟CE認證的一項強制性要求《低電壓指令》相關(guān)的安全性標準挑戰(zhàn)。與儀器制造商相關(guān)的標準是EN 61010－測量、控制和實驗室用電氣設(shè)備的安全要求。 </p> <p> 低電壓指令要求將校準器電壓限制為1,000Vrms。那么如何校準測試電壓高達5 kV 的兆歐表呢？這類儀器具有更寬的動態(tài)范圍，可測量高到10TΩ的電阻，并且提供了如上所述的保護端子，使其能夠準確測量非常高的電阻值。幸運的是，這樣的保護配置可以使其本身形成一個電阻倍增器，能夠有效地將一個已知電阻倍增為1000倍。同樣重要的是，由于倍增器是一個分立、隔離、**的設(shè)備，可以滿足倍增器所需的高電壓，它已經(jīng)不是《低電壓指令》所管轄的范圍。上海高壓絕緣電阻測試儀搖表耐壓測試儀絕緣電阻。</p><div

充電注意事項編輯1、儀表可采用交直流兩種方式供電，但在現(xiàn)場電源干擾較大或不穩(wěn)定時，推薦使用電池供電。2、***使用充電電池時，需充電6小時以上。否則儀表不能正常工作。3、充電電路采用**智能充電管理模塊，可自動停止充電。注意：充電適配器的交流輸入電壓范圍為220V±15%，以免接錯電源造成不必要的損失。4、將充電適配器的直流端插入儀表電源插孔⑨，另一端接通交流電源，充電指示燈（紅色）亮，快速充電開始。5、電池接近充滿后，充電指示燈（綠燈）亮，轉(zhuǎn)換到慢充狀態(tài)。經(jīng)過一端時間（1－2）小時可取下插頭停止充電開始使用儀表。注意：儀表不使用時，應(yīng)確保波段開關(guān)處于關(guān)閉狀態(tài)，以免電池過早用完。絕緣電阻測試儀器的概述圖V百科往期回顧詞條統(tǒng)計瀏覽次數(shù)：21717次編輯次數(shù)：7次歷史版本**近更新：w_ou（2018-07-04）突出貢獻榜 </p> <p> <br /> </p><p> 數(shù)字兆歐表4類常見故障 </p> <p> 為了保證數(shù)字兆歐表能正常工作，我們在這里簡要介紹一下4類常見的兆歐表故障： 1、電壓不穩(wěn)?？赡茉蛴腥齻€：*、調(diào)速器裝置螺絲松弛，調(diào)速輪摩擦點接觸不緊密；第二，調(diào)速器彈簧松動；第三，彈性不足。 2、無交流、直流輸出。可能原因應(yīng)該有三個：*、子線圈開路；第二、定子線圈脫焊，第三、二極管或電容器損壞。 3、無法搖動，即發(fā)電機有卡住現(xiàn)象或者搖動時很費力。主要原因有兩類：*是發(fā)電機轉(zhuǎn)子與極靴相碰或者是增速齒輪嚙合不好，第二是發(fā)電機轉(zhuǎn)子已損壞。 4、機殼漏電。大致原因應(yīng)該是內(nèi)部引線碰殼或發(fā)電機彈簧引出線碰殼或是由于受潮造成絕緣不良。用數(shù)字兆歐表測量絕緣時，為什么規(guī)定搖測時間為１分鐘？用兆歐表測量絕緣電阻時，一般規(guī)定以搖測一分鐘后的讀數(shù)為準備。因為在絕緣體上加上直流電壓后，流過絕緣體的電流（吸收電流）將隨時間的增長而逐漸下降。而絕緣的直流電阻率是根據(jù)穩(wěn)態(tài)傳導電流確定的，并且不同材料的絕緣體，其絕緣吸收電流的衰減時間也不同。但是試驗證明，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。絕緣電阻測試儀那個品牌的好？</p><div

1、試驗前應(yīng)拆除被試設(shè)備電源及一切對外連線，并將被試物短接后接地放電1min，電容量較大的應(yīng)至少放電2min以免觸電和影響測量結(jié)果。 </p> <p> 2、效驗儀表指針是否在無窮大上，否則需調(diào)整機械調(diào)零螺絲(7)。 </p> <p> 注意：在調(diào)整機械調(diào)零螺絲時，左右調(diào)整量為半圈。 </p> <p> 3、用干燥清潔的柔軟布擦去被試物的表面污垢，必要時先用汽油洗凈套管的表面積垢，以消除表面漏電電流影響測試結(jié)果。 </p> <p> 4、將帶高壓測試線（紅色）插入（2）LINE端，另一端探針或探鉤接于被試設(shè)備的高壓導體上，將測試線（綠色）插入（3）GUARD端，另一端接于被試設(shè)備的高壓護環(huán)上，以消除表面泄漏電流的影響（詳見“屏蔽端的使用方法”相關(guān)內(nèi)容。將另外一根黑色測試線插入地端（EARTH）（1）端，另一頭接于被試設(shè)備的外殼或地上。 </p> <p>
