特性參數

頻率響應

指變壓(ya)器次級輸出電壓(ya)隨(sui)工作頻(pin)率(lv)變化的特(te)性。

變壓器原理

通(tong)頻帶如(ru)果變(bian)壓(ya)(ya)器在中間頻率(lv)的輸(shu)出電壓(ya)(ya)為(wei)U0，當輸(shu)出電壓(ya)(ya)（輸(shu)入電壓(ya)(ya)保持(chi)不變(bian)）下降到0.707U0時的頻率(lv)范圍，稱為(wei)Sat變(bian)壓(ya)(ya)器的通(tong)頻帶B。

初、次級阻抗比

變(bian)壓(ya)器(qi)(qi)初、次級(ji)接入適當(dang)的(de)阻(zu)(zu)(zu)抗(kang)(kang)Ri和Ro，使變(bian)壓(ya)器(qi)(qi)初、次級(ji)阻(zu)(zu)(zu)抗(kang)(kang)匹配，則Ri和Ro的(de)比值稱為初、次級(ji)阻(zu)(zu)(zu)抗(kang)(kang)比。在阻(zu)(zu)(zu)抗(kang)(kang)匹配的(de)情況(kuang)下，變(bian)壓(ya)器(qi)(qi)工作在醉(zui)(zui)佳(jia)狀態，傳輸效率醉(zui)(zui)高(gao)。

變壓器運行前的檢測

聽 先將(jiang)變(bian)壓器空投(tou)（不帶負(fu)荷），電磁聲應無異常，不能(neng)有“吱吱”或“劈啪(pa)”響聲。

如以上幾方面全(quan)部合格，變(bian)壓器(qi)就(jiu)可以帶負荷正式運(yun)行了。

變壓器投入運(yun)行(xing)前，一(yi)定要進行(xing)一(yi)系列的檢(jian)查。
