style="text-indent:25px">過去在進行電纜耐壓試驗時都采用直流耐壓試驗。在1980年左右，國外電力部門發(fā)現(xiàn)直流耐壓試驗對橡塑絕緣是無效的且具有危害性。我國在九十年代開始研究和實踐交流耐壓試驗技術(shù)。經(jīng)過20多年的研究和實踐，世界各國紛紛采用交流耐壓試驗代替直流耐壓試驗。國內(nèi)外有關(guān)標(biāo)準(zhǔn)機構(gòu)也對于高壓電纜的試驗方法作出了更改和修訂。1997年CIGRI國際大電網(wǎng)工作會議對目前采用的直流耐壓試驗方法提出疑議，并推薦使用工頻及近似工頻（30-300HZ）的交流試驗方法，在全世界范圍內(nèi)推廣應(yīng)用。我國很多省份電網(wǎng)已先后頒發(fā)《試驗規(guī)程》，強制規(guī)定用交流耐壓試驗代替直流耐壓試驗。在我國電網(wǎng)相對發(fā)達的省份，交流耐壓試驗已經(jīng)成為強制性標(biāo)準(zhǔn)。其它地區(qū)的試驗規(guī)程也在起草和醞釀中。交流耐壓試驗取代傳統(tǒng)直流耐壓試驗已是大勢所趨。工廠需要定期對設(shè)備的電流電阻進行檢測，了解是否在正常的數(shù)值范圍。</p><div

style="text-indent:25px">拆過高頻變壓器的人都清楚，高頻變壓器的線圈都是由絕緣漆包裹的銅線繞成，層與層之間由絕緣膠帶纏繞，不留一絲縫隙，而高頻變壓器的絕緣線是由三層絕緣材質(zhì)包裹的銅線，雖然很薄，但卻能保證幾千伏的電壓無法擊穿。雖然高頻變壓器有這么強大的絕緣防護，但在測試時還是會有被高壓擊穿的變壓器，這是由什么原因造成的呢？經(jīng)過仔細的觀察，不難發(fā)現(xiàn)造成這種現(xiàn)象的主要原因是： 1、三層絕緣線與初級繞組間的交叉處沒有隔離，比如未穿套管等，在焊錫時三層絕緣線在被銅線導(dǎo)熱后，融傷了絕緣皮層，在后面工序測試時會產(chǎn)生很多高壓不良，而高壓測試是具有破壞性的測試，當(dāng)產(chǎn)品品質(zhì)處于高壓擊穿的臨界值時，多次測試也會出現(xiàn)高壓不良。 2、三層絕緣線與次級繞組間的交叉處沒有隔離，即使在焊錫時控制好，測試無高壓不良，但是產(chǎn)品在客戶處上波峰焊錫絲，針腳會再次受熱，同樣也會融傷絕緣層，造成高壓不良。變壓器測試儀，專門用來測量變壓器容量的儀器，同時也可測量變壓器的特性參數(shù)。遼寧全自動電子變壓器綜合測試臺</p><p style="text-indent:25px">變壓器按照不同的功能和大小可以分為很多種，比如，耦合變壓器，電源變壓器等等。電子變壓器的絕緣測試</p><p style="text-indent:25px">工作溫度變化時應(yīng)監(jiān)視變壓器。如果變壓器線圈導(dǎo)線為A級絕緣，則其絕緣主要是紙和棉紗，溫度對絕緣和使用壽命有很大影響，溫度每升高8℃，絕緣壽命將減少約50％。變壓器在常溫（90℃）下工作，使用壽命約20年。如果溫度升至105℃，則使用壽命為7年。如果溫度升至120℃，壽命將只有兩年。因此，當(dāng)變壓器運行時，必須保持良好的通風(fēng)和冷卻。必要時可采用強制通風(fēng)以減少變壓器的溫升。對于儀器相關(guān)的內(nèi)容想要了解更多的話可以登錄深圳市展榮新精密電子有限公司。電子變壓器的絕緣測試</p><p
