style="text-indent:25px">變壓器（Transformer）是利用電磁感應的原理來改變交流電壓的裝置，主要構件是初級線圈、次級線圈和鐵芯（磁芯）。主要功能有：電壓變換、電流變換、阻抗變換、隔離，湖北變壓器繞組檢測、穩(wěn)壓（磁飽和變壓器）等。按用途可以分為：電力變壓器和特殊變壓器（電爐變、整流變、工頻試驗變壓器、調壓器、礦用變、音頻變壓器、中頻變壓器、高頻變壓器、沖擊變壓器、儀用變壓器，湖北變壓器繞組檢測，湖北變壓器繞組檢測、電子變壓器、電抗器、互感器等）<p>作用：<p>變壓器是一種靜止的電氣設備。它是根據(jù)電磁感應的原理，將某一等級的交流電壓和電流轉換成同頻率的另一等級電壓和電流的設備。作用：變換交流電壓、交換交流電流和變換阻抗。高頻變壓器是通過初級線圈通過電壓使磁芯產生電磁磁通，從而使次級線圈感應產生電壓電流的變壓元件。湖北變壓器繞組檢測</p><div

變壓器的參數(shù)有勵磁參數(shù)和短路參數(shù),只有已知參數(shù),才能運用前面所介紹的基本方程式、等值電路或相量圖求解各量。對制造好的變壓器,其參數(shù)可通過實驗測得。 </p> <p> 空載實驗目的:通過測量空載電流和一、二次電壓及空載功率來計算變比、空載電流百分數(shù)、鐵損和勵磁阻抗。 </p> <p> 1.低壓側加電壓,高壓側開路，為了便于測量和安全,空載實驗一般在低壓繞組上加電壓,高壓繞組開路。 </p> <p> 2.空載電流和空載功率必須是額定電壓時的值，并以此求取勵磁參數(shù)； </p> <p> 3.若要的達到高壓側參數(shù)須折算。 </p> <p> <br /> 湖北變壓器繞組檢測變壓器的生產研發(fā)是非常復雜的，一般生產變壓器的廠家都是技術水平比較高的。</p><div

style="text-indent:25px">通過短路阻抗和負載損耗的測量，可以驗證這兩項指標是否在國家標準及用戶要求范圍內，同時還可以通過試驗發(fā)現(xiàn)繞組設計與制造及載流回路和結構的缺陷。 1、短路阻抗及負載損耗的測量，應當在試品的一個繞組的線端施加額定頻率，且近似正弦的電流，另一個繞組短路，各相處于同一個分接位置。測量應在50%～100.0%額定電流下進行；為避免繞組發(fā)熱對試驗結杲產生明顯誤差，試驗測量應迅速進行；同時準確記錄試驗時繞組溫度。 2、短路阻抗及負載損耗的測量與空載試驗的測量線路相同，只是測量中無需進行電壓波形校正。 3、短路阻抗及負載損耗的測量接線；對于額定電流很小的試品，儀表（電壓表及瓦特表電壓線圈）和電壓互感器的吸收電流在測量電流中不可忽略時，應將電壓取于電源。 4、短路阻抗是在額定頻率和參考溫度下，一對繞組中某一繞組端子之間的等效串聯(lián)阻抗；其百分數(shù)等于短路電壓與額定電壓之比，測量時應以三相電流的算術平均值為準。</p><p style="text-indent:25px">我們選擇試驗變壓器時，主要考慮以下幾點：（1）電壓。依據(jù)試品的要求，首先選用具有合適電壓的試驗變壓器，使試驗變壓器的高壓側額定電壓Un高于被試品的試驗電壓Us,即Un>Us。其次應檢查試驗變壓器所需的低壓側電壓，是否能和現(xiàn)場電源電壓，調壓器相匹配。（2）電流。試驗變壓器的額定輸出電流In應大于被試品所需的電流Is，即In>Is。被試品所需的電流可按其電容估算，Is=Us w Cx，其中Cx包括試品電容和附加電容（F）。（3）容量。根據(jù)試驗變壓器輸出的額定電流及額定電壓，便可確定試驗變壓器的容量，即P=UnIn。根據(jù)部頒標準規(guī)定，我國試驗變壓器的電壓等級有：5、10、25、35、50、100、150、300kV等；容量等級有：3、5、10、25、50、100、150、200kVA等。由計算結果，查部頒標準即可選出所需要的試驗變壓器。如有特殊要求，一般可向制造廠商訂購特殊規(guī)格的試驗變壓器。通過質量監(jiān)督標準,試驗變壓器用于對各種電氣產品、電器元件、絕緣材料等進行規(guī)定電壓下的絕緣強度試驗。</p><div

style="text-indent:25px">外觀檢查油箱的幾何形狀有無變形、套管有無裂痕、安全氣道的玻璃有無碎裂或壓力釋放閥有無噴油。然后吊心檢査，査看分接開關有無焰焊現(xiàn)象、引線機械緊固及絕緣包扎有無松動、開裂及變形，繞組有無變形、墊塊和各支撐件有無位移，各部位有無放電痕跡， zui后分別在高壓側與低壓側按短路試驗前的部位拍照，以進行比較。如果試驗中短路電流峰值與穩(wěn)定值、持續(xù)時間及試驗次數(shù)均達到GB 1094.5的規(guī)定；試驗中的波形和電抗與原始值比較，符合GB 1094.5的規(guī)定；且例行試驗復試項包括規(guī)定試驗電壓下的外施、感應及雷電沖擊試驗（如有規(guī)定）合格；在外觀及吊心檢查中油箱的幾何形狀無變形、高低壓套管與分接開關無損傷、繞組和支撐件無變形、標記無明顯位移、無放電痕跡、氣體繼電器中無氣體、壓力釋放閥無噴油等，則認為該產品經受住短路試驗考核，試驗合格；若以上任何一項超出了允許范圍和規(guī)定，則認為試驗不合格。試驗變壓器是發(fā)電廠、供電局及科研單位等廣大用戶的用來做交流耐壓試驗的基本試驗設備。肇慶電子變壓器綜合性能測試</p><p
