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(jì)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”，山東電子變壓器的耐壓試驗(yàn)。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，山東電子變壓器的耐壓試驗(yàn)，山東電子變壓器的耐壓試驗(yàn)，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)

(2)避雷器的接地線應(yīng)與變壓器低壓繞組中性點(diǎn)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(dāng)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，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(hù)變壓器的低壓繞組，同時還能保護(hù)當(dāng)雷電波從低壓繞組折換到高壓繞組時，不致使高壓繞組絕緣損壞。在變壓器的日常維護(hù)時需要注意觀察外觀，主要檢查變壓器外部是否存在滲油、是否存在零部件冒煙或放電現(xiàn)象。深圳高頻變壓器耐壓測試</p><p
