style="text-indent:25px">干式變壓器外部檢查項目：（1）檢查變壓器的套管、繞組樹脂絕緣外表層是否清潔、有無爬電痕跡和碳化現(xiàn)象；（2）變壓器高低壓套管引線接地緊密無發(fā)熱，并無裂紋及放電現(xiàn)象；（3）檢查緊固件、連接件、導電零件及其它零件有無生銹、腐蝕的痕跡及導電零件接觸是否良好；（4）檢查電纜和母線有無異常；（5）檢查風冷系統(tǒng)的溫度箱中電氣設備運行是否正常及信號系統(tǒng)有無異常；（6）在遮欄外細聽變壓器的聲音，判斷有無異常及運行是否正常；（7）檢查變壓器底座、欄桿、變壓器室電纜接地線等接地是否可靠良好；（8）用溫度檢查儀檢查接觸器部位及外殼溫度有無超標現(xiàn)象。</p><p style="text-indent:25px">三相變壓器應使用三相電源進行試驗，沒有三相電源也可使用單相電源；使用單相電源時，D聯(lián)結的繞組單相電源應施加在三角形的兩個角上；試驗期間該單相電源應相當于三相試驗的線電壓。Y聯(lián)結的繞組單相電源應施加于一個線端與另外兩個連在一起的線端上；試驗期間單相電壓應等于三相試驗時線電壓的√3/2倍。分級絕緣變壓器需考慮其中性點絕緣是否能夠滿足單相電源的試驗要求；Y聯(lián)結的變壓器，如電源容量不足且有中性點可以利用時，經(jīng)制造單位與用戶協(xié)商，可在線端與中性點間使用單相電源進行試驗。首先施加小于70%試驗電流進行調試；當合閘相角、試驗電流的峰值和對稱值及持續(xù)時間均達到要求時，再進行100.0%試驗電流的正式試驗；小于70%試驗電流不記人試驗次數(shù)。變壓器按用途可以分為：配電變壓器、組合式變壓器、干式變壓器、單相變壓器、整流變壓器、抗干擾變壓器等。</p><div

style="text-indent:25px">變壓器綜合測試臺的特點有： 1.可顯示測量電流和測量時間。 2.可儲存120次測量數(shù)據(jù)，斷電不丟失。 3.全部漢字菜單及操作提示，直觀方便。 4.測量數(shù)據(jù)穩(wěn)定。 5.智能化功率管理技術，可有效減輕儀器內部發(fā)熱。 6.高度智能化設計，功能設置巧妙先進，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.響應速度快，在測量狀態(tài)可以直接轉換分接開關，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，無須手動切換電流檔。深圳市展榮新精密電子有限公司目前專注于生產制造電子變壓器元器件測試儀這類設備。湖北變壓器例行試驗</p><p style="text-indent:25px">變壓器大家可能認為在公眾場合用的比較多，但其實在住宅小區(qū)中也有變壓器的存在。湖北變壓器例行試驗</p><p 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(jīng)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。湖北變壓器例行試驗</p><p
