變壓器是一種相對(duì)靜止的電氣設(shè)備，由繞在同一個(gè)鐵心上的兩個(gè)或兩個(gè)以上的繞組組成的，繞組之間通過(guò)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(jiǎn)單說(shuō)變壓器的工作原理就是“電生磁，磁生電”。變壓器的初級(jí)（一次）線圈和次級(jí)（二次）線圈共同繞在一個(gè)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(gè)磁通穿過(guò)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(shì)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(shì)分別為：E1/E2=U1/U2=N1/N2=K(k為變比)

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(lái)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

在非被試?yán)@組供給勵(lì)磁電壓，其大小應(yīng)使每匝電壓為1V； (2) 連接并聯(lián)支路的一端，測(cè)量各同名端的電勢(shì)差，其電勢(shì)差應(yīng)等于零；為了避免由于回路接觸不良造成電勢(shì)差為零，允許在測(cè)量中加入一匝，使電勢(shì)差為1V；臨時(shí)匝應(yīng)分別正繞與反繞串入回路，其電勢(shì)差均應(yīng)近似等于1V； (3) 為了避免因增加串聯(lián)匝數(shù)而使電勢(shì)差減小的現(xiàn)象，測(cè)量電勢(shì)差的電壓表應(yīng)盡量采用高內(nèi)阻的電壓表； (4) 電勢(shì)差試驗(yàn)時(shí)被試?yán)@組的電壓雖然只有1V，但其電位往往很高；在并聯(lián)支路中如有串聯(lián)線段，試驗(yàn)中可將其打開，分別測(cè)量幾個(gè)并聯(lián)支路的電勢(shì)差，以降低被試?yán)@組的電位； (5) 測(cè)量?jī)x表的一端應(yīng)可靠接地，儀表的量程開始應(yīng)置于zui大位罝，送電指示正常后，再逐級(jí)縮小量程，以避免損壞儀表。肇慶無(wú)局放試驗(yàn)變壓器</p><p
