在工廠的供電系統中(zhong)，變(bian)壓(ya)(ya)器(qi)(qi)是十(shi)分重要(yao)的一環。一般情(qing)況(kuang)下，變(bian)壓(ya)(ya)器(qi)(qi)是長期(qi)運(yun)行(xing)(xing)的，但是在實際(ji)運(yun)行(xing)(xing)過(guo)程(cheng)中(zhong)，變(bian)壓(ya)(ya)器(qi)(qi)會出(chu)現空載(zai)(zai)或(huo)輕載(zai)(zai)運(yun)行(xing)(xing)。那么，變(bian)壓(ya)(ya)器(qi)(qi)空載(zai)(zai)或(huo)輕載(zai)(zai)運(yun)行(xing)(xing)時用不(bu)用進行(xing)(xing)無功(gong)補償？變(bian)壓(ya)(ya)器(qi)(qi)空載(zai)(zai)或(huo)輕載(zai)(zai)運(yun)行(xing)(xing)又存在哪些問題呢(ni)？

一、變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)空(kong)載(zai)或(huo)輕(qing)載(zai)運(yun)行要不(bu)要無功(gong)(gong)補(bu)(bu)(bu)償(chang)(chang)？作為電(dian)(dian)感性(xing)負載(zai)設備，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)運(yun)行時需要消耗大量(liang)無功(gong)(gong)功(gong)(gong)率(lv)，而通過(guo)在(zai)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)附近(jin)安裝(zhuang)電(dian)(dian)力電(dian)(dian)容(rong)(rong)器(qi)(qi)，可以(yi)起(qi)到無功(gong)(gong)補(bu)(bu)(bu)償(chang)(chang)的作用。通過(guo)電(dian)(dian)力電(dian)(dian)容(rong)(rong)器(qi)(qi)進行無功(gong)(gong)補(bu)(bu)(bu)償(chang)(chang)，可以(yi)提(ti)高變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的利用率(lv)。在(zai)項目(mu)新建(jian)時期(qi)設計無功(gong)(gong)補(bu)(bu)(bu)償(chang)(chang)還可以(yi)減(jian)少變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的設計容(rong)(rong)量(liang)。當變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)空(kong)載(zai)或(huo)輕(qing)載(zai)運(yun)行時，同樣(yang)會消耗無功(gong)(gong)功(gong)(gong)率(lv)，如果(guo)不(bu)進行無功(gong)(gong)補(bu)(bu)(bu)償(chang)(chang)的話(hua)，企(qi)業(ye)功(gong)(gong)率(lv)因數會逐漸降(jiang)低，電(dian)(dian)能質量(liang)會下降(jiang)。企(qi)業(ye)電(dian)(dian)費也會增加，為了提(ti)高功(gong)(gong)率(lv)因素，建(jian)議企(qi)業(ye)通過(guo)合(he)理(li)安排工藝流(liu)程，避免變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)空(kong)載(zai)或(huo)輕(qing)載(zai)運(yun)行。

二、變壓(ya)器(qi)(qi)(qi)(qi)(qi)(qi)空載(zai)(zai)或(huo)(huo)輕載(zai)(zai)運行(xing)有(you)哪些影響？在(zai)變壓(ya)器(qi)(qi)(qi)(qi)(qi)(qi)空載(zai)(zai)運行(xing)時是(shi)(shi)存(cun)在(zai)一定損(sun)耗(hao)的(de)(de)。這個損(sun)耗(hao)叫做變壓(ya)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)空載(zai)(zai)損(sun)耗(hao)。當變壓(ya)器(qi)(qi)(qi)(qi)(qi)(qi)空載(zai)(zai)運行(xing)時，其二次側沒有(you)負(fu)荷(he)，不存(cun)在(zai)負(fu)荷(he)，但是(shi)(shi)在(zai)變壓(ya)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)一次測，一次測線圈在(zai)額定電壓(ya)的(de)(de)作用(yong)下會(hui)產生損(sun)耗(hao)。對(dui)于企(qi)業來說(shuo)，因為錯峰(feng)用(yong)電、生產淡季、法(fa)定節假日等因素，變壓(ya)器(qi)(qi)(qi)(qi)(qi)(qi)可(ke)能存(cun)在(zai)空載(zai)(zai)或(huo)(huo)輕載(zai)(zai)運行(xing)。但是(shi)(shi)在(zai)變壓(ya)器(qi)(qi)(qi)(qi)(qi)(qi)空載(zai)(zai)或(huo)(huo)輕載(zai)(zai)運行(xing)時，也(ye)要使(shi)用(yong)電力(li)電容(rong)器(qi)(qi)(qi)(qi)(qi)(qi)進行(xing)無功補償。但是(shi)(shi)具(ju)體補償多少(shao)容(rong)量(liang)？需(xu)要根據企(qi)業的(de)(de)實際情況選擇。
