絕緣電阻測(cè)量?jī)x在日常使用中的一些要點(diǎn) </p> <p> 絕緣電阻測(cè)量?jī)x是一種常用的測(cè)量?jī)x器，主要用于測(cè)量大型變壓器、互感器、發(fā)電機(jī)、高壓電動(dòng)機(jī)、電力電容、電力電纜、避雷器等設(shè)備的絕緣電阻。***小編主要來(lái)介紹一下絕緣電阻測(cè)量?jī)x的測(cè)量步驟，海南絕緣電阻測(cè)試儀選型，希望可以幫助用戶(hù)更好的應(yīng)用產(chǎn)品。測(cè)試儀在工作時(shí)，自身產(chǎn)生高電壓，而測(cè)量對(duì)象又是電氣設(shè)備，所以必須正確使用，否則就會(huì)造成人身或設(shè)備事故。在使用絕緣電阻測(cè)量?jī)x前，首先要做好以下各種準(zhǔn)備工作： 1、測(cè)量前必須將被測(cè)設(shè)備電源切斷，并對(duì)地短路放電，決不允許設(shè)備帶電進(jìn)行測(cè)量，以保證人身和設(shè)備的安全。 2、對(duì)可能感應(yīng)出高電壓的設(shè)備，必須消除這種可能性后才能進(jìn)行測(cè)量。 3、被測(cè)物表面要清潔，海南絕緣電阻測(cè)試儀選型，減少接觸電阻，海南絕緣電阻測(cè)試儀選型，確保測(cè)量結(jié)果的正確性。如何判斷各種型號(hào)絕緣電阻測(cè)試儀精度高低-深圳茂迪。海南絕緣電阻測(cè)試儀選型</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

1.測(cè)量前，應(yīng)將兆歐表保持水平位置，左手按住表身，右手搖動(dòng)兆歐表?yè)u柄，轉(zhuǎn)速約120r/min，指針應(yīng)指向無(wú)窮大(∞)，否則說(shuō)明兆歐表有故障。 2.測(cè)量前，應(yīng)切斷被測(cè)電器及回路的電源，并對(duì)相關(guān)元件進(jìn)行臨時(shí)接地放電，以保證人身與兆歐表的安全和測(cè)量結(jié)果準(zhǔn)確。 3.測(cè)量時(shí)必須正確接線(xiàn)，測(cè)量回路對(duì)地電阻時(shí)，L端與回路的裸露導(dǎo)體連接，E端連接接地線(xiàn)或金屬外殼;測(cè)量回路的絕緣電阻時(shí)，回路的首端與尾端分別與L、E連接;測(cè)量電纜的絕緣電阻時(shí)，為防止電纜表面泄漏電流對(duì)測(cè)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(xiàn)柱引出的測(cè)量軟線(xiàn)絕緣應(yīng)良好，兩根導(dǎo)線(xiàn)之間和導(dǎo)線(xiàn)與地之間應(yīng)保持適當(dāng)距離，以免影響測(cè)量精度。 5.搖動(dòng)兆歐表時(shí)，不能用手接觸兆歐表的接線(xiàn)柱和被測(cè)回路，以防觸電。絕緣電阻測(cè)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(cè)試儀、高壓絕緣電阻測(cè)試儀、絕緣電阻測(cè)量?jī)x、絕緣特性測(cè)試儀、電動(dòng)搖表、數(shù)字搖表、數(shù)顯搖表、數(shù)字兆歐計(jì)、高壓數(shù)字絕緣電阻測(cè)試儀。海南絕緣電阻測(cè)試儀選型絕緣電阻表使用方法圖片。</p><div

</p><p> 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(xiàn)、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(kāi)始，而是從1兆歐或2兆歐開(kāi)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。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

3、無(wú)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(lèi)：*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(xiàn)碰殼或發(fā)電機(jī)彈簧引出線(xiàn)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(guò)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(guò)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(lái)確定絕緣性能的好壞。海南絕緣電阻測(cè)試儀選型</p><p
