style="text-indent:25px">繞制材料：要繞制一個(gè)變壓器我們必須對(duì)與變壓器有關(guān)的材料要有一定的認(rèn)識(shí)，為此這里我就介紹一下這方面的知識(shí)。1、鐵芯材料變壓器使用的鐵芯材料是鐵片中加入硅能降低鋼片的導(dǎo)電性，增加電阻率，它可減少渦流，使其損耗減少。我們通常稱(chēng)為加了硅的鋼片為硅鋼片，變壓器的質(zhì)量所用的硅鋼片的質(zhì)量有很大的關(guān)系，硅鋼片的質(zhì)量通常用磁通密度B來(lái)表示，一般黑鐵片的B值為6000-8000、低硅片為9000-11000，高硅片為12000-16000。2、繞制變壓器通常用的材料漆包線，紗包線，絲包線紙包線，較常用的漆包線。對(duì)于導(dǎo)線的要求，是導(dǎo)電性能好，絕緣漆層有足夠耐熱性能，并且要有一定的耐腐蝕能力。一般情況下較好用QZ型號(hào)的較強(qiáng)度的聚脂漆包線。</p><p style="text-indent:25px">檢測(cè)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(lái)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(cè)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(cè)判斷電源變壓器是否有短路性故障的簡(jiǎn)單方法是測(cè)量空載電流(測(cè)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(jué)。此時(shí)不用測(cè)量空載電流便可斷定變壓器有短路點(diǎn)存在。深圳市展榮新精密電子有限公司目前專(zhuān)注于生產(chǎn)制造電子變壓器元器件測(cè)試儀這類(lèi)設(shè)備。</p><div

style="text-indent:25px">測(cè)定電動(dòng)機(jī)三相繞組頭尾的兩種方法：在電動(dòng)機(jī)6根引出線標(biāo)記無(wú)法確認(rèn)時(shí)，我們可利用交流電源和燈泡檢查電動(dòng)機(jī)三相繞組的頭尾端，以免將繞組接錯(cuò)。用交流電源和燈泡確定電動(dòng)機(jī)三相繞組的方法是：首先用36V低壓燈做試燈，分出電動(dòng)機(jī)每一相線圈的兩個(gè)線端，然后將兩相線圈串接后通入220V電源，剩下的一相線圈兩端接36V的燈泡線路通入電源后，燈泡發(fā)亮，說(shuō)明所串聯(lián)的兩相是頭尾相接；燈泡不亮，說(shuō)明是頭頭相接，如圖26(a)所示。然后將測(cè)出的兩相線圈頭尾做一標(biāo)記，再按此方法將其中一相與原來(lái)接燈泡的一相線圈串聯(lián)，另一相連接燈泡，再按同樣道理判斷，電動(dòng)機(jī)三相繞組的頭尾就很容易區(qū)分出來(lái)了。另一種方法是用萬(wàn)用表測(cè)定電動(dòng)機(jī)三相繞組頭尾，首先用萬(wàn)用表測(cè)量出電動(dòng)機(jī)6個(gè)接線端哪兩個(gè)線端為同一相，然后將萬(wàn)用表的直流毫安擋撥到較小一擋，并將表筆接到三相繞組的某一組兩端，而電池正負(fù)極接到另一相的兩個(gè)線端上。在變壓器的日常檢查中還要著重關(guān)注吸濕器的檢查。惠州變壓器綜合檢測(cè)儀</p><p
