class="title">詳細說明</p><div id="ibvsofr" class="box"><p><p> 1、變壓器定義、作用 </p> <p> 變壓器是一種相對靜止的電氣設(shè)備，由繞在同一個鐵心上的兩個或兩個以上的繞組組成的，繞組之間通過交變的磁通的相互聯(lián)系。為了把發(fā)電廠發(fā)出的電能經(jīng)濟的傳輸，遼寧電子變壓器有載開關(guān)檢測儀、合理的分配以及安全的使用，都要用到電力變壓器。 </p> <p> 2、變壓器工作原理 </p> <p> 簡單說變壓器的工作原理就是“電生磁，磁生電”。變壓器的初級（一次）線圈和次級（二次）線圈共同繞在一個鐵芯上，當(dāng)一次線圈通入電壓U1后，在鐵芯中產(chǎn)生交變磁通，這個磁通穿過一次繞組和二次繞組，根據(jù)電磁感應(yīng)定律，在一次繞組和二次繞組中分別產(chǎn)生感應(yīng)電勢E1和E2。根據(jù)電磁感應(yīng)定律可知，一次側(cè)、二次側(cè)繞組的感應(yīng)電勢分別為：E1/E2=U1/U2=N1/N2=K(k為變比) </p> <p> <br /> 通過質(zhì)量監(jiān)督標準，遼寧電子變壓器有載開關(guān)檢測儀,試驗變壓器用于對各種電氣產(chǎn)品，遼寧電子變壓器有載開關(guān)檢測儀、電器元件、絕緣材料等進行規(guī)定電壓下的絕緣強度試驗。遼寧電子變壓器有載開關(guān)檢測儀</p><div style="width:100%;text-align:

style="text-indent:25px">電壓比測量是驗證變壓器能否達到預(yù)期的電壓變換效果。絕緣裝配后的電壓比試驗是檢驗繞組的匝數(shù)與繞向是否正確；引線裝配后的電壓比試驗時間檢查分接開關(guān)與繞組的聯(lián)結(jié)組標號是否正確；總裝后的電壓比試驗是檢査變壓器分接開關(guān)內(nèi)部所處位置與外部指示位置是否一致及線端標志是否正確。對于有并聯(lián)支路的繞組，如果在電壓比試驗中可以明顯的發(fā)現(xiàn)一匝的誤差時，應(yīng)分別對每個支路進行電壓比測量；否則應(yīng)進行電勢差試驗，以確保并聯(lián)支路的匝數(shù)相等，在此前提下方能進行電壓比測量。深圳超輕型試驗變壓器日常在使用變壓器的時候要注意使用規(guī)范。</p><div

style="text-indent:25px">變壓器幾乎在所有的電子產(chǎn)品中都要用到，它原理簡單但根據(jù)不同的使用場合（不同的用途）變壓器的繞制工藝會有所不同的要求。變壓器的功能主要有：電壓變換；阻抗變換；隔離；穩(wěn)壓（磁飽和變壓器）等，變壓器常用的鐵心形狀一般有E型和C型鐵心。一般降壓變壓器一次繞組的電阻值為幾十至幾百歐，二次繞組為幾歐至幾十歐，這點要做到心中大致有數(shù)，為選萬用表的量程提供參考，一般選用萬用表的R×1或R×10檔，分別測一次繞組和二次繞組，查看有無斷路和短路問題，這個方法有個缺點就是，無法檢測出局部短路問題，這個缺憾可以通過通電檢查彌補。變壓器綜合測試儀一般在使用前一定要經(jīng)過嚴格的培訓(xùn)。</p><div

style="text-indent:25px">變壓器里起決定性作用的還是電壓的比，這是一定不會變化的，從這點來說也應(yīng)該是恒壓做起來比較容易。遼寧電子變壓器有載開關(guān)檢測儀</p><p style="text-indent:25px">配電變壓器的防雷保護接線具體要求如下： (1)一般要求避雷器安裝在跌開式熔斷器和變壓器之間，避雷器要求盡量靠近變壓器安裝，距離越近越好。 (2)避雷器的接地線應(yīng)與變壓器低壓繞組中性點及變壓器金屬外殼連接在一起共同接地，亦稱作“三位一體”的接地方式。這種接法的目的是保證當(dāng)變壓器高壓側(cè)受雷擊引起避雷器放電時，變壓器主絕緣所承受的電壓*是避雷器的殘壓，而接地裝置上的電壓并不作用在變壓器主絕緣上，使避雷器與變壓器得到較好的絕緣配合，能減少高、低壓繞組間和高壓繞組對變壓器外殼之間發(fā)生絕緣擊穿的危險。 (3)對于低壓，架空線路引出3~10kV，Y，yn0配電變壓器，為防止低壓側(cè)落雷造成絕緣擊穿事故，要求在配電變壓器低壓出線上安裝一組低壓避雷器，這樣不*可保護變壓器的低壓繞組，同時還能保護當(dāng)雷電波從低壓繞組折換到高壓繞組時，不致使高壓繞組絕緣損壞。遼寧電子變壓器有載開關(guān)檢測儀</p><p
