4.測量數(shù)據(jù)穩(wěn)定。 5.智能化功率管理技術(shù)，可有效減輕儀器內(nèi)部發(fā)熱。 6.高度智能化設(shè)計，功能設(shè)置巧妙先進，可自動判斷測試線虛接、斷線等故障。 7.保護功能完善，能可靠保護反電勢對儀器的沖擊，具有自動放電指示功能。 8.響應(yīng)速度快，在測量狀態(tài)可以直接轉(zhuǎn)換分接開關(guān)，儀器會自動提示，新的電阻值很快就會顯示出來。 9.自動程控電流源技術(shù)，無須手動切換電流檔。</p><p

1、短路阻抗及負載損耗的測量，應(yīng)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(yīng)在50%～100.0%額定電流下進行；為避免繞組發(fā)熱對試驗結(jié)杲產(chǎn)生明顯誤差，試驗測量應(yīng)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(yīng)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(yīng)以三相電流的算術(shù)平均值為準。開關(guān)變壓器線圈之間存在漏感，是因為線圈之間存在漏磁通而產(chǎn)生的。</p><div style="width:100%;text-align: center;"><img

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?zāi)康?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(cè)加電壓,高壓側(cè)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(cè)參數(shù)須折算。 </p> <p> <br /> 變壓器對電子元器生產(chǎn)要求還是比較高的。江西高壓變壓器測試</p><p
