無功補償原理
首先(xian)你要了解什么叫無功(gong)功(gong)率(lv)(lv)。
無功(gong)功(gong)率(lv)(lv)就是(shi)不(bu)消耗電(dian)(dian)(dian)能的用(yong)(yong)電(dian)(dian)(dian)設備所消耗的功(gong)率(lv)(lv)，在電(dian)(dian)(dian)力(li)系統中(zhong)，無功(gong)功(gong)率(lv)(lv)用(yong)(yong)來建立磁(ci)場(chang)(chang)，作為(wei)(wei)交換能量使用(yong)(yong)，他們由電(dian)(dian)(dian)能轉化為(wei)(wei)磁(ci)場(chang)(chang)，再(zai)由磁(ci)場(chang)(chang)轉化換為(wei)(wei)電(dian)(dian)(dian)能，對外部電(dian)(dian)(dian)路不(bu)做(zuo)工。但是(shi)無功(gong)功(gong)率(lv)(lv)并不(bu)是(shi)無用(yong)(yong)之功(gong)。沒有(you)這部分功(gong)率(lv)(lv)，就不(bu)能建立感應磁(ci)場(chang)(chang)，電(dian)(dian)(dian)動機(ji)變壓器(qi)等用(yong)(yong)電(dian)(dian)(dian)設備就不(bu)能正(zheng)常(chang)工作，對無功(gong)補(bu)償(chang)的補(bu)償(chang)原則(ze)是(shi)既不(bu)能少(shao)補(bu)，也不(bu)能補(bu)償(chang)過(guo)量。
很多電(dian)(dian)(dian)氣設備的無功(gong)功(gong)率(lv)(lv)比較大，所以(yi)要對它進行無功(gong)補(bu)償(chang)，把這樣的無(wu)功(gong)功(gong)率(lv)補償進去(qu)以后，能提高功率因素(su)。改(gai)善(shan)用電(dian)質(zhi)量(liang)。
