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

電子測量儀器通用規(guī)范二、術語與定義1、空載電流當額定頻率下的額定電壓（分接電壓）施加到一個繞組的端子，其他繞組開路時，流經(jīng)該繞組線路端子電流的方均根值。2、空載損耗當額定頻率下的額定電壓（分接電壓）施加到一個繞組的端子，其他繞組開路時所吸取的有功功率。3、負載損耗在一對繞組中，當額定電流（分接電流）流過一個繞組的線路端子，且另一個繞組短路時，變壓器在額定頻率及參考溫度下所吸取的有功功率。一定要在電流穩(wěn)定后再計數(shù)，必要時需采取縮短充電時間的措施。安微變壓器故障檢測儀</p><p style="text-indent:25px">做三相變壓器的空載、負載試驗時，儀器能自動判斷接線是否正確。江門變壓器測試系統(tǒng)</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變壓器高壓側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。江門變壓器測試系統(tǒng)</p><p
