特性參數

頻率響應

指變(bian)壓器次級輸出(chu)電(dian)壓隨工作頻率變(bian)化的(de)特性(xing)。

變壓器原理

通頻帶(dai)如果變(bian)壓(ya)器在中間頻率(lv)的(de)(de)輸(shu)出電(dian)壓(ya)為U0，當輸(shu)出電(dian)壓(ya)（輸(shu)入電(dian)壓(ya)保持不變(bian)）下降到0.707U0時的(de)(de)頻率(lv)范圍，稱(cheng)為Sat變(bian)壓(ya)器的(de)(de)通頻帶(dai)B。

初、次級阻抗比

變壓器(qi)初、次級接入適當的(de)阻抗(kang)Ri和(he)Ro，使變壓器(qi)初、次級阻抗(kang)匹(pi)配，則Ri和(he)Ro的(de)比值(zhi)稱為初、次級阻抗(kang)比。在(zai)阻抗(kang)匹(pi)配的(de)情況下，變壓器(qi)工作在(zai)醉佳(jia)狀態，傳輸效率醉高(gao)。

明(ming)泰(tai)電(dian)(dian)(dian)(dian)氣（蘇(su)州）有(you)限公司是正泰(tai)集團在蘇(su)州地區一家授權的經(jing)銷企(qi)業，連續十年銷量居正泰(tai)營銷網絡(luo)名，公司主要經(jing)營“正泰(tai)”牌(pai)配電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)器(qi)(qi)、控制電(dian)(dian)(dian)(dian)器(qi)(qi)、終端電(dian)(dian)(dian)(dian)器(qi)(qi)、電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)器(qi)(qi)、電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)子、儀(yi)器(qi)(qi)儀(yi)表、建筑電(dian)(dian)(dian)(dian)器(qi)(qi)、高壓電(dian)(dian)(dian)(dian)器(qi)(qi)及成套設備。

變壓器運行前的檢測

看 1.油(you)(you)位：是否合適。高了，在變壓器投入運行(xing)帶上負荷(he)后，油(you)(you)溫上升(sheng)，油(you)(you)膨脹，很可能使油(you)(you)從(cong)油(you)(you)枕頂(ding)部的呼(hu)吸器連通管處溢出。低了，對變壓器的絕緣和冷卻(que)作用會降低，正泰(tai)變壓器供應，影響變壓器運行(xing)，嚴(yan)重者會燒(shao)壞變壓器。

2.蓋板、套(tao)管、油位計、排油閥：是(shi)否密封良好，有(you)無(wu)滲漏油現(xian)象。否則(ze)當變壓器帶上負荷后，在熱狀(zhuang)態下，會發生更嚴(yan)重(zhong)的(de)滲漏現(xian)象。套(tao)管有(you)無(wu)裂紋(wen)和放電現(xian)象

3.變壓器的外(wai)殼接地(di)：是否牢固可(ke)靠(kao)。因(yin)為它對變壓器和抄表人員起著直接的保護作用。

4.變壓(ya)器(qi)一、二次出線套(tao)管(guan)及它(ta)與導線的(de)連接：是否(fou)良(liang)好，正泰(tai)變壓(ya)器(qi)供應商，相色(se)是否(fou)正確。

5.計量表，表箱：是否(fou)傾斜、損壞（投運(yun)(yun)后(hou)，還要看(kan)計量表運(yun)(yun)行是否(fou)正常），封條、手續是否(fou)完(wan)整。

6.熔(rong)絲：選(xuan)擇是(shi)否合理。變壓器一次額(e)定電流(liu)的(de)1.5~2倍，二(er)次熔(rong)絲的(de)選(xuan)用標準通常是(shi)變壓器的(de)二(er)次額(e)定電流(liu)。

工作原理

變(bian)壓(ya)器由鐵(tie)芯(xin)（或磁芯(xin)）和線圈(quan)(quan)組(zu)成，線圈(quan)(quan)有兩個(ge)(ge)(ge)或兩個(ge)(ge)(ge)以上(shang)的(de)(de)(de)繞(rao)組(zu)，其中接電源的(de)(de)(de)繞(rao)組(zu)叫(jiao)初(chu)級(ji)線圈(quan)(quan)，常(chang)州正(zheng)泰變(bian)壓(ya)器，其余的(de)(de)(de)繞(rao)組(zu)叫(jiao)次(ci)級(ji)線圈(quan)(quan)。它可以變(bian)換交流電壓(ya)、電流和阻(zu)抗。的(de)(de)(de)鐵(tie)心變(bian)壓(ya)器由一個(ge)(ge)(ge)軟(ruan)磁材料做(zuo)成的(de)(de)(de)鐵(tie)心及套在鐵(tie)心上(shang)的(de)(de)(de)兩個(ge)(ge)(ge)匝數不等的(de)(de)(de)線圈(quan)(quan)構成

鐵(tie)心的(de)(de)作(zuo)用是加強兩個線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)間的(de)(de)磁耦合。為(wei)了(le)減少鐵(tie)內渦流(liu)和(he)磁滯損(sun)耗(hao)，鐵(tie)心由涂漆的(de)(de)硅鋼片(pian)疊壓(ya)而(er)成;兩個線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)之間沒有電(dian)的(de)(de)聯系，線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)由絕(jue)緣銅線(xian)(xian)(xian)（或鋁線(xian)(xian)(xian)）繞成。一個線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)接交(jiao)流(liu)電(dian)源稱為(wei)初(chu)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)（或原線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)），另一個線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)接用電(dian)器(qi)(qi)(qi)稱為(wei)次(ci)級(ji)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)（或副(fu)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)）。實際的(de)(de)變(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)是很復(fu)雜的(de)(de)，正泰變(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)價格，不可(ke)避(bi)免地(di)存在銅損(sun)（線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)電(dian)阻發(fa)熱）、鐵(tie)損(sun)（鐵(tie)心發(fa)熱）和(he)漏磁（經空(kong)氣閉合的(de)(de)磁感應線(xian)(xian)(xian)）等(deng)，為(wei)了(le)簡化討論(lun)這里只介(jie)紹理想變(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)。理想變(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)成立的(de)(de)條件是：忽(hu)(hu)略漏磁通(tong)，忽(hu)(hu)略原、副(fu)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)的(de)(de)電(dian)阻，忽(hu)(hu)略鐵(tie)心的(de)(de)損(sun)耗(hao)，忽(hu)(hu)略空(kong)載(zai)電(dian)流(liu)（副(fu)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)開路原線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)中的(de)(de)電(dian)流(liu)）。例如電(dian)力變(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)在滿載(zai)運行時（副(fu)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)輸出額定功率）即接近(jin)理想變(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)情況。
