style="text-indent:25px">變壓器絕緣主要分為主絕緣與縱絕緣兩種。主絕緣主要是指線圈自身以外的其他結(jié)構(gòu)的絕緣，包括油箱、鐵芯等位置的絕緣；縱絕緣是指變壓器繞阻在不同電位的各個點(diǎn)及部位之間的絕緣，如線圈匝間絕緣等。為了更好掌握變壓器絕緣承受過電壓的能力，一般情況下，根據(jù)變壓器絕緣等級的情況分為交流耐壓試驗(yàn)和感應(yīng)耐壓試驗(yàn)兩項(xiàng)試驗(yàn)。那么對于交流耐壓試驗(yàn)和感應(yīng)耐壓試驗(yàn)兩項(xiàng)試驗(yàn)的具體步驟是什么，他們對應(yīng)的實(shí)驗(yàn)結(jié)果都是什么樣的，我們后續(xù)和小編一起來了解一下。</p><p

style="text-indent:25px">變壓器交流耐壓試驗(yàn)設(shè)備：交流耐壓試驗(yàn)中，通常我們會遇到的電力試驗(yàn)設(shè)備包括“串聯(lián)諧振耐壓試驗(yàn)裝置”、“干式試驗(yàn)變壓器”、“感應(yīng)耐壓試驗(yàn)裝置”。（1）串聯(lián)諧振試驗(yàn)裝置：變頻串聯(lián)諧振試驗(yàn)裝置是運(yùn)用串聯(lián)諧振原理，利用勵磁變壓器激發(fā)串聯(lián)諧振回路，調(diào)節(jié)變頻控制器的輸出頻率，使回路電感L和試品C串聯(lián)諧振，諧振電壓即為加到試品上電壓。變頻諧振試驗(yàn)裝置普遍適用于電力、冶金、石油、化工等行業(yè)，適用于大容量，高電壓的電容性試品的交接和預(yù)防性試驗(yàn)。(2)干式試驗(yàn)變壓器：按交流耐壓試驗(yàn)規(guī)程，各種大型電力變壓器、電力電纜、汽輪及水輪發(fā)電機(jī)及其它容性設(shè)備都必須嚴(yán)格定期進(jìn)行交流耐壓試驗(yàn)。我們常用的干式試驗(yàn)變壓器分為一體式高壓試驗(yàn)變壓器（30kV以下）和分體式試驗(yàn)變壓器兩類。如何能夠確保自己購買的變壓器直流電阻測試儀發(fā)揮出它原有的檢測性能，才能夠凸顯出它的高價值。成都變壓器絕緣測試</p><p style="text-indent:25px">變壓器變比檢測儀都有哪些規(guī)格型號，我們一起來了解。成都變壓器絕緣測試</p><p 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(qiáng)大的絕緣防護(hù)，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(xì)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。成都變壓器絕緣測試</p><p
