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阻抗；其百分數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> 1、變壓器定義、作用 </p> <p> 變壓器是一種相對靜止的電氣設備，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系。為了把發(fā)電廠發(fā)出的電能經濟的傳輸、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，當一次線圈通入電壓U1后，在鐵芯中產生交變磁通，這個磁通穿過一次繞組和二次繞組，根據電磁感應定律，在一次繞組和二次繞組中分別產生感應電勢E1和E2。根據電磁感應定律可知，一次側、二次側繞組的感應電勢分別為：E1/E2=U1/U2=N1/N2=K(k為變比) </p> <p> <br /> 隨著變壓器空載負載測試儀被普遍使用，逐漸成為用電稽查人員真正的好助手。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="湖北電子變壓器絕緣系統(tǒng),變壓器"

style="text-indent:25px">通過測定變壓器高低壓側繞組的電壓、空載電流和空載損耗, 求得變壓器變比和激磁阻抗參數。湖北電子變壓器絕緣系統(tǒng)</p><p style="text-indent:25px">電勢差試驗方法及注意事項如下： (1) 在非被試繞組供給勵磁電壓，其大小應使每匝電壓為1V； (2) 連接并聯支路的一端，測量各同名端的電勢差，其電勢差應等于零；為了避免由于回路接觸不良造成電勢差為零，允許在測量中加入一匝，使電勢差為1V；臨時匝應分別正繞與反繞串入回路，其電勢差均應近似等于1V； (3) 為了避免因增加串聯匝數而使電勢差減小的現象，測量電勢差的電壓表應盡量采用高內阻的電壓表； (4) 電勢差試驗時被試繞組的電壓雖然只有1V，但其電位往往很高；在并聯支路中如有串聯線段，試驗中可將其打開，分別測量幾個并聯支路的電勢差，以降低被試繞組的電位； (5) 測量儀表的一端應可靠接地，儀表的量程開始應置于zui大位罝，送電指示正常后，再逐級縮小量程，以避免損壞儀表。湖北電子變壓器絕緣系統(tǒng)</p><p
