style="text-indent:25px">變壓器的品質(zhì)好壞對聲音的影響很大，因為變壓器的傳輸能量與鐵芯、線圈密切關聯(lián)，其傳遞速率對聲音的影響起決定性作用。像EI型變壓器，人們通常覺得它的中頻比較厚，高頻則比較纖細，為什么呢?因為它的傳輸速度相對比較慢。而環(huán)型呢?低頻比較猛，中高頻則又稍弱一點，為什么?因為它傳輸速度比較快，但是如果通過有效的結(jié)構(gòu)改變，你就可以把環(huán)型和EI型都做得非常完美，所以關鍵還是要看你怎么做。不過至少可以肯定一點的是，R型變壓器不是太容易做好。用它來做小電流的前級功放和CD唱機電源還可以，如果用來做后級功放的電源，則有比較嚴重的缺陷。因為R型變壓器本身的結(jié)構(gòu)形式不太容易改變，而環(huán)型和EI型則相對容易通過改變結(jié)構(gòu)來達到靚聲目的。采用R型變壓器制作的功率放大器電源，通常聲音很板結(jié)而匱乏靈氣，低頻往往沒有彈跳力而顯得較硬。深圳變壓器性能綜合測試臺可精確測量各種配電變壓器的容量，方便、準確。</p><div

style="text-indent:25px">電壓比測量所使用的儀器的精度和靈敏度均不應低于0.2%；電壓比測量中計算的比值應按各分接的銘牌電壓計算，當電壓百分數(shù)或?qū)褦?shù)與銘牌電壓無差異時，可按電壓頁分數(shù)或匝數(shù)計算的比值。測量應分別在各分接上進行；有正、反勵磁的有載調(diào)壓變壓器，轉(zhuǎn)換選擇器正向連接時，如在所有分接選擇器位置進行了電壓比測量，反向連接時，允許只抽試1～2個分接。三繞組變壓器至少在包括***對繞組在內(nèi)的兩對繞組上分別進行電壓比測量。絕緣裝配后的半成品電壓比測量，三相應分別進行相的電壓比測量；同時應檢查繞組的電壓矢量關系（繞向與標志）是否正確。引線裝配后或總裝配后的電壓比測量應分別對各分接進行電壓比測量，如果可能還應驗證聯(lián)結(jié)組及電壓矢量關系是否正確。</p><p style="text-indent:25px">變壓器測試儀功能特性：1. 所有測試結(jié)果均自動進行相關校正。儀器可自動進行諸如：波形校正、溫度校正、非額定電壓校正、非額定電流校正等多種校正，使測試結(jié)果準確度更高。2. 320x240大屏幕、高亮度的液晶顯示，全漢字菜單及操作提示實現(xiàn)友好的人機對話，觸摸按鍵使操作更簡便，寬溫液晶帶亮度調(diào)節(jié)，可適應冬夏各季。3. 儀器可以由用戶預設40組被試品參數(shù)，而且這些參數(shù)可以根據(jù)需要隨時刪除和增加，使用非常方便。4. 自帶實時電子鐘，自動記錄試驗的日期、時間利于實驗結(jié)果的保存、管理。5. 面板式熱敏打印機，可現(xiàn)場快速打印試驗結(jié)果。6. 數(shù)據(jù)（試品設置、測量結(jié)果、測試時間等）具備掉電存貯及瀏覽功能，可以存儲500組實驗結(jié)果，能與計算機聯(lián)機傳送數(shù)據(jù)。允許外接電壓互感器和電流互感器進行擴展量程測量，可測量任意參數(shù)的被試品。正是因為變壓器的存在才能夠讓我們的電壓即便在天氣惡劣的時候也是非常的穩(wěn)定。</p><div
