class="title">詳細說明</p><div id="a7gl3vw" class="box"><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(cè)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，肇慶實驗變壓器，yn0配電變壓器，為防止低壓側(cè)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，肇慶實驗變壓器，同時還能保護當雷電波從低壓繞組折換到高壓繞組時，肇慶實驗變壓器，不致使高壓繞組絕緣損壞。日常在使用變壓器的時候要注意使用規(guī)范。肇慶實驗變壓器</p><div

1、變壓器定義、作用 </p> <p> 變壓器是一種相對靜止的電氣設備，由繞在同一個鐵心上的兩個或兩個以上的繞組組成的，繞組之間通過交變的磁通的相互聯(lián)系。為了把發(fā)電廠發(fā)出的電能經(jīng)濟的傳輸、合理的分配以及安全的使用，都要用到電力變壓器。 </p> <p> 2、變壓器工作原理 </p> <p> 簡單說變壓器的工作原理就是“電生磁，磁生電”。變壓器的初級（一次）線圈和次級（二次）線圈共同繞在一個鐵芯上，當一次線圈通入電壓U1后，在鐵芯中產(chǎn)生交變磁通，這個磁通穿過一次繞組和二次繞組，根據(jù)電磁感應定律，在一次繞組和二次繞組中分別產(chǎn)生感應電勢E1和E2。根據(jù)電磁感應定律可知，一次側(cè)、二次側(cè)繞組的感應電勢分別為：E1/E2=U1/U2=N1/N2=K(k為變比)

style="text-indent:25px">高壓變壓器容量測試儀是我公司專門研制開發(fā)的用于變壓器容量測量和損耗參數(shù)測量的高精度儀器。高壓變壓器容量測試儀采用高效可充電電池，無需外接電源即可工作，充電時可連續(xù)測量500次一次；同時內(nèi)部數(shù)字合成三相標準正弦波信號（不簡單逆變交流輸出，保證測試數(shù)據(jù)在非定額條件下的準確性），功放可提供三相精密交流測試。高壓變壓器容量測試儀在測量變壓器容量和變壓器短路損耗時，不需要外部三相測試電源和電壓調(diào)節(jié)器和上電流等輔助設備，簡化了接線，大幅提高了工作效率，測試結(jié)果精度達到99%。</p><p style="text-indent:25px">變壓器在安裝的時候需要注意以下事項： 1.應當安裝在供電范圍的負荷中心，一般都是比較靠近大的負荷。 2.安裝位置必須安全可靠，運輸方便，便于吊裝檢修，符合城鎮(zhèn)規(guī)劃。這點是相對比較重要的。 3.對于安在變壓器桿上的，應保證足夠堅固，臺面距地應有3米高，應有警示標志，接地線應有護套，不得裝于大的轉(zhuǎn)角桿、分支桿；不易巡視吊裝的電桿；架空線、接戶線過多的電桿。一定要保證用電的安全以及人員安全，避免造成不必要的事故。 4.按說3米還是滿足安全距離的。應該讓開窗戶，以不影響采光、通風、觀景，以人為本嘛，環(huán)境的舒適敞亮。變壓器是利用電磁感應原理，從一個電路向另一個電路傳遞電能或傳輸信號的一種電器。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

變壓器容量計算首先選擇變壓器的額定電壓。高壓側(cè)電壓與所接入電網(wǎng)電壓相等，低壓側(cè)電壓比低壓側(cè)電網(wǎng)的電壓高10%或5%（取決變壓器電壓等級和阻抗電壓大?。活~定容量選擇。計算變壓器所帶負荷的大小（要求統(tǒng)計比較大綜合負荷，將有功負荷kW值換算成視在功率kVA），如果是兩臺變壓器，那么每臺變壓器的容量可按照比較大綜合負荷的70%選擇，一臺變壓器要按總負荷考慮，并留有適當?shù)脑６?。其它明星參?shù)可結(jié)合變壓器產(chǎn)品適當考慮。例如：選擇35/10kV變壓器。假定比較大負荷為3500kW，功率因數(shù)為，選兩臺變壓器，容量S=×3500/，可選擇3150kVA的變壓器，電壓比為35kV/。再從產(chǎn)品目錄中選擇型號。一、變壓器容量計算公式：1、計算負載的每相比較大功率將A相、B相、C相每相負載功率**相加，如A相負載總功率10KW，B相負載總功率9KW，C相負載總功率11KW，取比較大值11KW。(注：單相每臺設備的功率按照銘牌上面的比較大值計算，三相設備功率除以3，等于這臺設備的每相功率。)例如：C相負載總功率=電腦300W×10臺)+(空調(diào)2KW×4臺)=11KW2、計算三相總功率11KW×3相=33KW(變壓器三相總功率)3、計算變壓器總功率三相總功率/，這是重要的步驟。肇慶實驗變壓器</p><p
