/>2、如果用戶需要，我廠生產(chǎn)的TQSB系列試驗(yàn)變壓器，抽出200V的串級(jí)抽頭，可將二臺(tái)或三臺(tái)串級(jí)成交流100kV、150kV、200kV、300kV的高電壓。也可根據(jù)用戶的需要，在高壓繞組中抽出5～15kV的中壓抽頭，供高壓電機(jī)作交流耐壓試驗(yàn)；<br />3、表格中"直流高壓輸出"一欄，為交直流兩用試驗(yàn)變壓器的直流高壓輸出值；<br />4、我廠還可根據(jù)用戶的要求，定制各種特殊規(guī)格的試驗(yàn)變壓器。<br />五、操作步驟<br />1、按接線原理圖連接好引線，并將變壓器和控制箱可靠接地；<br />2、試驗(yàn)前，檢查各部位的接線是否接觸良好，并檢查控制箱的調(diào)壓器是否調(diào)至"零"位；<br />3、接通電源，綠色指示燈亮，按下啟動(dòng)按鈕，紅色指示燈亮，表示變壓器已通電，等待升壓；<br />4、順時(shí)針勻速旋轉(zhuǎn)調(diào)壓器手柄，進(jìn)行升壓，并密切注意儀表指示以及試品的情況；<br />5、試驗(yàn)完畢后，應(yīng)迅速將電壓降至零位，并按下停止按鈕，然后切斷電源，解開(kāi)試驗(yàn)引線。<br />六、注意事項(xiàng)<br />1、做高壓試驗(yàn)時(shí)，必須由2人或2個(gè)以上人員參加，并明確做好分工，明確相互間的方法。并有專人監(jiān)護(hù)現(xiàn)場(chǎng)安全及觀察試品的試驗(yàn)狀態(tài)；<br />2、變壓器和控制箱應(yīng)有可靠的接地；<br />3、試驗(yàn)過(guò)程中，升壓速度不能太快，也決不允許突然全電壓通電或斷電；<br />4、在升壓或耐壓試驗(yàn)過(guò)程中，如發(fā)現(xiàn)下列不正常情況時(shí)，應(yīng)立即降壓，并切斷電源，停止試驗(yàn)，查明原因后再做試驗(yàn)。① 電壓表指針擺動(dòng)很大；② 發(fā)現(xiàn)絕緣燒焦的異味、冒煙現(xiàn)象；③ 被測(cè)試品內(nèi)有不正常的聲音。<br />5、試驗(yàn)中，如果試品短路或故障擊穿，控制箱中的過(guò)流繼電器工作，此時(shí)，將調(diào)壓器回至零位，并切斷電源后，方可將試品取出。<br />6、進(jìn)行電容試驗(yàn)或進(jìn)行直流高壓泄漏試驗(yàn)時(shí)，試驗(yàn)完畢后，將調(diào)壓器降至零位后，并切斷電源，然后，應(yīng)用放電棒將試品或電容器的高壓端對(duì)地進(jìn)行放電，以免存留在電容中的電勢(shì)發(fā)生觸電危險(xiǎn)。<br />七、試驗(yàn)變壓器的容量選擇<br />標(biāo)稱試驗(yàn)變壓器容量Pn的確定公式：<br />Pn=kVn2WCt10-9<br />式中：Pn-標(biāo)稱試驗(yàn)變壓器容量（kVA）；<br />k -安全系數(shù)；<br />Vn-試驗(yàn)變壓器的額定輸出高壓的有效值（kV）；<br />W -角頻率，W=2πf,f為試驗(yàn)電源的頻率；<br />Ct-被試品的電容量（PF）。<br />對(duì)于不同的試驗(yàn)電壓Vn，選擇適當(dāng)?shù)陌踩禂?shù)k，標(biāo)稱試驗(yàn)電壓較低時(shí)，k值可取高一些；以下列出不同的試驗(yàn)電壓Vn，所選用的安全系數(shù)k值，供參考：<br />Vn=50～100kV k=4；<br />Vn=150～300kV k=3；<br />Vn≥300kV k=2；<br />Vn≥1MV k=1。<br />被測(cè)試設(shè)備的電容量Ct可由交流電橋測(cè)出。Ct的變化很大，應(yīng)由設(shè)備的類型而定。典型數(shù)據(jù)如下：<br />棒形或懸式絕緣子幾十微法；<br />電壓互感器 200～500PF；<br />分級(jí)套管 100～1000PF；<br />電力變壓器＜1000kVA ～1000PF；<br />電力變壓器＞1000kVA 1000～10000PF；<br />高壓電力電纜和油浸紙絕緣 250～300PF/m；<br />氣體絕緣～60PF/m；<br />封閉變電站，SF6氣體絕緣 100～10000PF。<br />八、附件<br />1、使用說(shuō)明書 1份；<br />2、產(chǎn)品合格證 1份；<br />3、產(chǎn)品出廠試驗(yàn)報(bào)告 1份。<br />我廠對(duì)所有產(chǎn)品實(shí)行"三包"，歡迎用戶選用我廠的產(chǎn)品，對(duì)我廠的產(chǎn)品質(zhì)量提出寶貴的改進(jìn)性意見(jiàn)</p> <div id="sh7gbfdki" class="pagetb"> <p> 上一條：<a
