變壓器運行前的檢測

測(ce) 用1000~2500伏(fu)兆(zhao)歐表測(ce)量變壓(ya)器(qi)的(de)一(yi)、二次繞組對地絕(jue)緣(yuan)電阻和繞組間的(de)絕(jue)緣(yuan)電阻，醉低(di)值(zhi)不能低(di)于(yu)25~130歐阻。

變(bian)壓器安裝后投(tou)入(ru)運行(xing)前，必須測量各分接位(wei)置的直(zhi)(zhi)流(liu)電(dian)阻，以保證接觸良好。配電(dian)變(bian)壓器各相(xiang)直(zhi)(zhi)流(liu)電(dian)阻的相(xiang)互(hu)差值應小(xiao)(xiao)于(yu)平均(jun)值的4％，線間直(zhi)(zhi)流(liu)電(dian)阻的相(xiang)互(hu)差值應小(xiao)(xiao)于(yu)平均(jun)值的2％。

空投(tou)運上(shang)后，還要測量二次側電壓是(shi)否平衡，如平衡說明(ming)變壓器變比正常，無匝間短(duan)路(lu)。

發展歷史

1884年，路(lu)森·戈拉爾和約(yue)翰(han)·狄(di)克遜(xun)·吉布(bu)斯在(zai)采(cai)用電力照明的意大(da)利(li)都(dou)靈(ling)市(shi)展示了他們的設備。早期(qi)變壓器(qi)采(cai)用直線(xian)型鐵(tie)心，后來被更有效的環形(xing)鐵(tie)心取代。

西屋公司的(de)(de)工程師威廉(lian)·史坦雷從喬(qiao)治·威斯汀(ting)豪斯、路森·戈拉爾與約翰·狄克(ke)遜·吉布(bu)斯買來(lai)變(bian)壓(ya)器以(yi)后，在1885年制(zhi)造了一臺實(shi)用的(de)(de)變(bian)壓(ya)器。后來(lai)變(bian)壓(ya)器的(de)(de)鐵心由E型的(de)(de)鐵片疊(die)合(he)而(er)成，并于1886年開始商業(ye)運用。
