隨著現(xiàn)代化技術(shù)的不斷更新和拓展，對電力系統(tǒng)及高電壓設(shè)備的可靠性也提出更高的要求，電氣設(shè)備出現(xiàn)事故或是損壞，通常與絕緣的缺陷密切相關(guān)。電氣設(shè)備的大容量化、高電壓化、結(jié)構(gòu)多樣化及密封化，對電氣設(shè)備應(yīng)提出更新的、更高的要求。大容量設(shè)備的使用不斷增加，用普通的兆歐表無法檢測其絕緣性能。電力試驗(yàn)規(guī)程對眾多的電力設(shè)備如：電纜、電機(jī)、發(fā)電機(jī)、變壓器、互感器、高壓開關(guān)、避雷器等要求做一系列的絕緣性能試驗(yàn)，首先是要做絕緣電阻測試。在測試大容量電力設(shè)備的絕緣電阻時，絕緣電阻值和加壓的時間有關(guān)，加壓時間越長，絕緣阻值越高，這種現(xiàn)象叫絕緣的吸收現(xiàn)象。要了解被試品的絕緣性能必須首先對其做吸收比和極化指數(shù)試驗(yàn)，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。我公司依照電力標(biāo)準(zhǔn)化規(guī)程特推出大容量、高抗干擾、性能穩(wěn)定的絕緣電阻測試儀，對電力設(shè)備進(jìn)行絕緣、吸收比、極化指數(shù)試驗(yàn)，為系列絕緣試驗(yàn)提供前期準(zhǔn)確判斷。北京絕緣電阻測試儀電流500v搖表測絕緣多少合格？</p><div

指針式絕緣電阻表準(zhǔn)備工作（1）試驗(yàn)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。（2）校驗(yàn)儀表指針是否在無窮大上，否則需調(diào)整機(jī)械調(diào)零螺絲⑦。注意：在調(diào)整機(jī)械調(diào)零螺絲時，左右調(diào)整量為半圈。（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。（4）將高壓測試線一端（紅色）插入②LINE端，另一端接于或使用掛鉤掛在被試設(shè)備的高壓導(dǎo)體上，將綠色測試線一端插入③GUARD端，另一端接于被試設(shè)備的高壓護(hù)環(huán)上，以消除表面泄漏電流的影響（詳見“屏蔽端（GUARD）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。注意：在接線時，特別注意LINE（紅色）與GUARD（綠色）的接法，不要將其短路。 </p><p style="text-indent:25px">（6）需連續(xù)進(jìn)行第二次測量時，可按3-5步驟執(zhí)行。注意：如長期不進(jìn)行測試，需將電池倉中的電池拿出，以免電池液滲漏損壞儀表。 3. 屏蔽端（GUARD）的使用方法在電力電纜等的絕緣測量或外界電磁場干擾時，為了消除表面漏電和外界電磁場的干擾而影響測量結(jié)果的準(zhǔn)確度，在實(shí)際測量過程中，采用儀表的屏蔽端來消除漏電電流、屏蔽干擾。對于兩節(jié)及以上的被試品，例如避雷器、耦合電容可采用圖5所示的接線進(jìn)行測量。圖中將屏蔽端接到被測避雷器上一節(jié)法蘭上，這樣，由上方高壓線路等所引起的干擾電流由屏蔽端子屏蔽掉，而不經(jīng)過測試主回路，從而避免了干擾電流的影響。對**上節(jié)避雷器，可將其上法蘭接儀表地端（EARTH）后再接地，使干擾電流直接入地。但后者不能將干擾完全消除掉。

幾乎所有的絕緣測試儀都采用直流電壓作為激勵，所以兆歐表校準(zhǔn)器的交流要求很少。許多兆歐表為兩端設(shè)備，它提供一個電壓，并測量由被測設(shè)備所決定的電流。量程達(dá)到1TΩ 以及更高的兆歐表通常具有第三個端子，稱為保護(hù)端（Guard），對于消除泄漏通路以及被測未知電阻Rx的并聯(lián)元件非常有用。保護(hù)端的目的是消除可能會產(chǎn)生的泄漏電流來選擇性地將輸出寄生電阻性元件的影響減小為零。 </p> <p> 絕緣測試儀，通常被稱為數(shù)字兆歐表或高阻計(jì)，***用于測量發(fā)電機(jī)、馬達(dá)、電源變壓器、配線、電器和其它電氣裝置（如控制、信號、通信和電源的電纜）的絕緣電阻。數(shù)字式絕緣電阻測試儀。北京絕緣電阻測試儀電流</p><p style="text-indent:25px">10kv絕緣電阻測試儀報(bào)價是多少_深圳茂迪。北京絕緣電阻測試儀電流</p><p style="text-indent:25px">4、測量前要檢查測試儀是否處于正常工作狀態(tài)下，主要檢查其"0"和"∞"兩點(diǎn)位置。即搖動手搖發(fā)電機(jī)手柄，使電機(jī)達(dá)到額定轉(zhuǎn)速。測試儀在短路時，指針應(yīng)指在"0"位置；開路時，指針應(yīng)指在"∞"位置。 5、測試儀使用時應(yīng)放在平穩(wěn)、牢固的地方，且遠(yuǎn)離大的外電流導(dǎo)體和外磁場。絕緣電阻測量儀注意 1、在測量電阻前，待測電路必須完全放電，并且與電源電路完全隔離。 2、如測試筆或電源適配器破損需更換，必須換上同型號和相同電氣規(guī)格的測試筆或電源適配器。 3、電池指示器批示電能耗盡時，不要使用儀器。若長時間不使用儀器，請將電池取出后存放。 4、不要在高溫、高濕、易燃、易爆和強(qiáng)電磁場環(huán)境中存放或使用本儀器。 5、請使用濕布或清潔劑來清潔儀器外殼，請勿使用磨擦物或溶劑。 6、儀器潮濕時，請先干燥后存儲。
