絕緣測試儀，通常被稱為數(shù)字兆歐表或高阻計，***用于測量發(fā)電機、馬達、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。它們往往被用于例行維護程序中來指示電機在數(shù)月或數(shù)年內(nèi)絕緣電阻的變化。絕緣電阻發(fā)生大的變化，就可能預(yù)示著潛在的故障。所以，就需要對兆歐表進行定期校準，以確保儀表本身沒有隨時間發(fā)生變化。 </p> <p> 兆歐表通過用一個電壓激勵被測裝置或網(wǎng)絡(luò)，然后測量激勵所產(chǎn)生的電流，利用歐姆定律測量出電阻。優(yōu)良的兆歐表校準器包括各種可選的電阻器，這點與現(xiàn)代校準器利用合成電阻功能提供的電阻器差別不大。兆歐表校準器與直流/低頻校準器的不同之處在于所需的電阻器范圍，以及耐受的電壓能力不同。例如，與數(shù)字多用表（DMM）上配備的歐姆表功能相比，這些電氣測試器在進行電阻測量時施加的電壓要高得多。兆歐表采用的電壓范圍通常從50V到高達5 kV；而典型數(shù)字多用表的電壓一般小于10 V。對于絕緣測試來說，需要測量的電阻值范圍很大，其上限可達到10TΩ，所需的電壓更高。貴州絕緣電阻測試儀價格絕緣電阻測試儀的使用方法和標準。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">選用要求和使用前的檢查(1)應(yīng)按被測電氣元件工作時的額定電壓來選擇儀表的電壓等級。測量埋置在繞組內(nèi)和其他發(fā)熱元件中的熱敏元件等的絕緣電阻時，一般應(yīng)選用250V規(guī)格的絕緣電阻表。(2)使用前，應(yīng)先檢查表和其引出線是否正常。將兩條引出線短路，搖動儀表或打開儀表電源開關(guān)進人測量狀態(tài)，儀表的指針偏轉(zhuǎn)到0處或數(shù)字指示值為0，再將兩條引出線斷開進行測量，指示值為∞，則說明正常。如圖二所示。接線和測量(1)測量電機等一般電器時，儀表的L端與被測元件(例如繞組)相接，E端與機殼相接；測量電纜時，除上述規(guī)定外，還應(yīng)將儀表的G端與被測電纜的護套連接。使用手搖式兆歐表時，手搖的轉(zhuǎn)速應(yīng)在120r/min左右，搖動到指示值穩(wěn)定后讀數(shù)。(2)測量之后，用導(dǎo)體對被測元件(例如繞組)與機殼之間放電后拆下引接線。直接拆線有可能被儲存的電荷電擊</p><p> 三、更換保險絲為避免受到電擊或電弧的燒傷，而造成人身傷害或儀表損壞，必須根據(jù)以下步驟更換保險絲，只能用同樣型號的或相同規(guī)格的保險絲進行更換。 1)按power鍵關(guān)閉電源，并從端子上把表筆或測試導(dǎo)線拆下，使測試導(dǎo)線與被測電路完全斷開。 2)把電池蓋的兩顆螺絲、殼體后蓋二顆螺絲以及電池后的一顆螺絲拆下，并把電池蓋和殼體后蓋取下。 3)輕輕地把保險絲的一端撬起，取出被燒壞的保險絲，并更換同樣型號的或相同電氣規(guī)格的保險絲。要確認保險絲已可靠地夾緊在保險絲夾的中間。保險規(guī)格：f1a240v。 4)合上電池蓋和殼體后蓋后，并把四顆螺絲緊固，在鎖緊之前，請不要使用儀表。

絕緣電阻測量儀在日常使用中的一些要點 </p> <p> 絕緣電阻測量儀是一種常用的測量儀器，主要用于測量大型變壓器、互感器、發(fā)電機、高壓電動機、電力電容、電力電纜、避雷器等設(shè)備的絕緣電阻。***小編主要來介紹一下絕緣電阻測量儀的測量步驟，希望可以幫助用戶更好的應(yīng)用產(chǎn)品。測試儀在工作時，自身產(chǎn)生高電壓，而測量對象又是電氣設(shè)備，所以必須正確使用，否則就會造成人身或設(shè)備事故。在使用絕緣電阻測量儀前，首先要做好以下各種準備工作： 1、測量前必須將被測設(shè)備電源切斷，并對地短路放電，決不允許設(shè)備帶電進行測量，以保證人身和設(shè)備的安全。 2、對可能感應(yīng)出高電壓的設(shè)備，必須消除這種可能性后才能進行測量。 3、被測物表面要清潔，減少接觸電阻，確保測量結(jié)果的正確性。天津智能雙顯絕緣電阻測試儀</p><p>
