style="text-indent:25px">檢測判別各繞組的同名端。在使用電源變壓器時(shí)，有時(shí)為了得到所需的次級(jí)電壓，可將兩個(gè)或多個(gè)次級(jí)繞組串聯(lián)起來使用。采用串聯(lián)法使用電源變壓器時(shí)，參加串聯(lián)的各繞組的同名端必須正確連接，不能搞錯(cuò)。否則，變壓器不能正常工作。I.電源變壓器短路性故障的綜合檢測判別。電源變壓器發(fā)生短路性故障后的主要癥狀是發(fā)熱嚴(yán)重和次級(jí)繞組輸出電壓失常。通常，線圈內(nèi)部匝間短路點(diǎn)越多，短路電流就越大，而變壓器發(fā)熱就越嚴(yán)重。檢測判斷電源變壓器是否有短路性故障的簡單方法是測量空載電流(測試方法前面已經(jīng)介紹)。存在短路故障的變壓器，其空載電流值將遠(yuǎn)大于滿載電流的10％。當(dāng)短路嚴(yán)重時(shí)，變壓器在空載加電后幾十秒鐘之內(nèi)便會(huì)迅速發(fā)熱，用手觸摸鐵芯會(huì)有燙手的感覺。此時(shí)不用測量空載電流便可斷定變壓器有短路點(diǎn)存在。江蘇變壓器需要那些檢測變壓器測試儀：專門用來測量變壓器容量的儀器，同時(shí)也可測量變壓器的特性參數(shù)。</p><div

行輸出變壓器又稱逆程變壓器、回掃變壓器，俗稱行輸出，它是電視機(jī)、顯示器中的一個(gè)重要變壓器。1.行輸出變壓器結(jié)構(gòu)行輸出變壓器的全部繞組和高壓整流管均密封在其中，底部引出各個(gè)繞組的引腳，高壓輸出采用高壓引線直接送至顯像管的高壓嘴。有的行輸出變壓器上只有一個(gè)電壓調(diào)節(jié)旋鈕，那是用來調(diào)節(jié)顯像管聚焦極電壓的。記憶行輸出變壓器兩個(gè)旋鈕位置的方法參考如圖3-44所示的兩個(gè)電壓調(diào)節(jié)電路。圖3-44兩個(gè)電壓調(diào)節(jié)電路重要提示一體化行輸出變壓器體積小，重量輕，省去了硅柱，工作穩(wěn)定性好。內(nèi)部的高壓整流二極管將各級(jí)繞組隔離，減小了分布電容，能獲得優(yōu)良的高壓負(fù)載特性。但是，由于行輸出變壓器工作在高壓、高頻狀態(tài)下，故障發(fā)生率相對(duì)電視機(jī)中其他元器件而言比較高，而且大多數(shù)情況下是高壓繞組部分損壞。由于一體化行輸出變壓器采用環(huán)氧樹脂等材料封裝，所以更換時(shí)得整個(gè)行輸出變壓器一起更換，增加了維修成本。2.行輸出變壓器電路符號(hào)圖3-45所示是行輸出變壓器電路符號(hào)。其中，圖3-45(a)所示為分立式行輸出變壓器的電路符號(hào)，圖3-45(b)所示是一體化行輸出變壓器的電路符號(hào)。用虛線框表示兩組繞組組合成一體，并在內(nèi)部設(shè)有高壓整流管。</p><p style="text-indent:25px">空載試驗(yàn)：從變壓器的某一繞組（一般從二次低壓側(cè)）施加正弦波額定頻率的額定電壓，其余繞組開路，測量空載電流和空載損耗。如果試驗(yàn)條件有限，電源電壓達(dá)不到額定電壓，可在非額定電壓條件下試驗(yàn)，這種試驗(yàn)方法誤差較大，一般只用于檢查變壓器有無故障，只有試驗(yàn)電壓達(dá)到額定電壓的80%以上才可用來測試空載損耗。短路試驗(yàn)：將變壓器低壓大電流側(cè)人工短聯(lián)接，從電壓高的一側(cè)線圈的額定分接頭處通入額定頻率的試驗(yàn)電壓，使繞組中電流達(dá)到額定值，然后測量輸入功率和施加的電壓（即短路損耗和短路電壓）以及電流值。通常試驗(yàn)電源的容量應(yīng)為被試品容量的30％。自帶面板式微型打印機(jī)，可漢化打印測量結(jié)果。</p><div

(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(shí)，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(duì)變壓器外殼之間發(fā)生絕緣擊穿的危險(xiǎn)。 (3)對(duì)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(shí)還能保護(hù)當(dāng)雷電波從低壓繞組折換到高壓繞組時(shí)，不致使高壓繞組絕緣損壞。江蘇變壓器需要那些檢測</p><p
