變壓器是一種相對靜止的電氣設(shè)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(dāng)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(yīng)定律，在一次繞組和二次繞組中分別產(chǎn)生感應(yīng)電勢E1和E2。根據(jù)電磁感應(yīng)定律可知，一次側(cè)、二次側(cè)繞組的感應(yīng)電勢分別為：E1/E2=U1/U2=N1/N2=K(k為變比) </p> <p> <br /> </p><p style="text-indent:25px">三相變壓器應(yīng)使用三相電源進(jìn)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(jié)的繞組單相電源應(yīng)施加在三角形的兩個角上；試驗期間該單相電源應(yīng)相當(dāng)于三相試驗的線電壓。Y聯(lián)結(jié)的繞組單相電源應(yīng)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(yīng)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(jié)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(jìn)行試驗。首先施加小于70%試驗電流進(jìn)行調(diào)試；當(dāng)合閘相角、試驗電流的峰值和對稱值及持續(xù)時間均達(dá)到要求時，再進(jìn)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)。電力變壓器的不正常運行可能會導(dǎo)致機器損壞，如果做好日常維護(hù)工作，將會保證變壓器的安全和順利運行。</p><div
