A）電池電壓不足。電池電壓欠壓過低，造成電路不能正常工作，所以測出的讀數(shù)是不準(zhǔn)確的。 </p> <p> B）測試線接法不正確。誤將"L"、"G"、"E"三端接線接錯，或?qū)?G"、"L"連線"G"、"E"連線接在被測試品兩端。 </p> <p> C） "G"端連線未接。被測試品由于受污染潮濕等因素造成電流泄漏引起的誤差，造成測試不準(zhǔn)確，此時必須接好"G"端連線防止泄漏電流引起誤差。 </p> <p> D）干擾過大。如果被測試品受環(huán)境電磁干擾過大，造成儀表讀數(shù)跳動?；蛑羔樆蝿?。造成讀數(shù)不準(zhǔn)確。 </p> <p> E）人為讀數(shù)錯誤。在用指針式絕緣電阻測試儀測量時，由于人為視角誤差或標(biāo)度尺誤差造成示值不準(zhǔn)確。 </p> <p> F）儀表誤差。儀表本身誤差過大，需要重新校對。 </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(diǎn)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?？赡茉驊?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(jī)有卡住現(xiàn)象或者搖動時很費(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(zhǔn)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(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。智能雙顯絕緣電阻測試儀。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東耐壓絕緣電阻測試儀哪個品牌好,絕緣電阻測試儀" src="https://tyunfile.71360.com/UploadFile/szmdjd/637377741198359375/8992300.png"></div><p> 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(zhǔn)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(rèn)證的一項強(qiáng)制性要求《低電壓指令》相關(guān)的安全性標(biāo)準(zhǔn)挑戰(zhàn)。與儀器制造商相關(guān)的標(biāo)準(zhǔn)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(zhǔn)器電壓限制為1,000Vrms。那么如何校準(zhǔn)測試電壓高達(dá)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(hù)端子，使其能夠準(zhǔn)確測量非常高的電阻值。幸運(yùn)的是，這樣的保護(hù)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。數(shù)字絕緣電阻測試儀報價_深圳茂迪。山東耐壓絕緣電阻測試儀哪個品牌好</p><p style="text-indent:25px">絕緣電阻測試國家標(biāo)準(zhǔn)。山東耐壓絕緣電阻測試儀哪個品牌好</p><p> 絕緣電阻表怎么使用 </p> <p> 1.測量前，應(yīng)將兆歐表保持水平位置，左手按住表身，右手搖動兆歐表搖柄，轉(zhuǎn)速約120r/min，指針應(yīng)指向無窮大(∞)，否則說明兆歐表有故障。 2.測量前，應(yīng)切斷被測電器及回路的電源，并對相關(guān)元件進(jìn)行臨時接地放電，以保證人身與兆歐表的安全和測量結(jié)果準(zhǔn)確。 3.測量時必須正確接線，測量回路對地電阻時，L端與回路的裸露導(dǎo)體連接，E端連接接地線或金屬外殼;測量回路的絕緣電阻時，回路的首端與尾端分別與L、E連接;測量電纜的絕緣電阻時，為防止電纜表面泄漏電流對測量精度產(chǎn)生影響，應(yīng)將電纜的屏蔽層接至G端。 4.兆歐表接線柱引出的測量軟線絕緣應(yīng)良好，兩根導(dǎo)線之間和導(dǎo)線與地之間應(yīng)保持適當(dāng)距離，以免影響測量精度。 5.搖動兆歐表時，不能用手接觸兆歐表的接線柱和被測回路，以防觸電。絕緣電阻測試儀有：兆歐表、數(shù)字兆歐表、數(shù)字式兆歐表、數(shù)顯兆歐表、絕緣表、絕緣電阻測試儀、高壓絕緣電阻測試儀、絕緣電阻測量儀、絕緣特性測試儀、電動搖表、數(shù)字搖表、數(shù)顯搖表、數(shù)字兆歐計、高壓數(shù)字絕緣電阻測試儀。山東耐壓絕緣電阻測試儀哪個品牌好</p><p>
