style="text-indent:25px">物質(zhì)介紹：在電器設(shè)備和無(wú)線電路中，[1]變壓器常用作升降電壓、匹配阻抗，安全隔離等。在發(fā)電機(jī)中，不管是線圈運(yùn)動(dòng)通過(guò)磁場(chǎng)或磁場(chǎng)運(yùn)動(dòng)通過(guò)固定線圈，均能在線圈中感應(yīng)電勢(shì)，此兩種情況，磁通的值均不變，但與線圈相交鏈的磁通數(shù)量卻有變動(dòng)，這是互感應(yīng)的原理。變壓器就是一種利用電磁互感應(yīng)，變換電壓，電流和阻抗的器件。變壓器的較基本形式，包括兩組繞有導(dǎo)線之線圈，并且彼此以電感方式稱(chēng)合一起。當(dāng)一交流電流（具有某一已知頻率）流于其中之一組線圈時(shí)，于另一組線圈中將感應(yīng)出具有相同頻率之交流電壓，而感應(yīng)的電壓大小取決于兩線圈耦合及磁交鏈之程度。</p><p style="text-indent:25px">識(shí)別電源變壓器：1）從外形識(shí)別：常用電源變壓器的鐵芯有E形和C形兩種。E形鐵芯變壓器呈殼式結(jié)構(gòu)（鐵芯包裹線圈），采用D41.D42很好硅鋼片作鐵芯，應(yīng)用普遍。C形鐵芯變壓器用冷軋硅鋼帶作鐵芯，磁漏小，體積小，呈芯式結(jié)構(gòu)（線圈包裹鐵芯）。2）從繞組引出端子數(shù)識(shí)別：電源變壓器常見(jiàn)的有兩個(gè)繞組，即一個(gè)初級(jí)和一個(gè)次級(jí)繞組，因此有四個(gè)引出端。有的電源變壓器為防止交流聲及其他干擾，初、次級(jí)繞組間往往加一屏蔽層，其屏蔽層是接地端。因此，電源變壓器接線端子至少是4個(gè)。高度調(diào)節(jié)及過(guò)濾的WRT-10的電流輸出允許在大型電力變壓器上做繞組電阻測(cè)量。</p><div

style="text-indent:25px">變壓器滲漏油的原因分析：1、橡膠密封件失效和焊縫開(kāi)裂變壓器的焊點(diǎn)多、焊縫長(zhǎng)，而油浸式變壓器是以鋼板焊接殼體為基礎(chǔ)的多種焊接和連接的體。一臺(tái)31500kVA變壓器的總焊點(diǎn)達(dá)70余處，焊縫總長(zhǎng)近20m左右，因此滲漏途徑可能較多。直接滲漏的原因是橡膠密封件失效和焊縫開(kāi)裂、氣孔、夾渣等。2、密封膠件老化、龜裂、變形變壓器滲漏多發(fā)生在連接處，而95 %以上主要是由密封膠件引起的。密封膠件質(zhì)量的好壞主要取決于它的耐油性能，耐油性能較差的，老化速度就較快，特別是在高溫下，其老化速度就更快，極易引起密封件老化、龜裂，變質(zhì)、變形，以至失效，造成變壓器滲漏油。采用新的單片機(jī)，內(nèi)部有鋰電池供電，支持?jǐn)?shù)據(jù)存儲(chǔ)及U盤(pán)轉(zhuǎn)存，實(shí)現(xiàn)打印等微機(jī)處理。江西變壓器的耐壓試驗(yàn)</p><p style="text-indent:25px">變壓器是利用電磁感應(yīng)原理，從一個(gè)電路向另一個(gè)電路傳遞電能或傳輸信號(hào)的一種電器。浙江變壓器檢測(cè)儀器</p><p> 行輸出變壓器又稱(chēng)逆程變壓器、回掃變壓器，俗稱(chēng)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(shù)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。浙江變壓器檢測(cè)儀器</p></p><br
