在電力系統中,電力用戶采用了大量的感應電動機和其他感應電氣設備。他們除了吸收系統的有功功率進行工作外,還需要電力系統提供大量的無功功率,在多級傳輸線和變壓器的傳輸和轉換之后,無功功率損失并且電網的功率因數降低。這不僅降低了發電和供電設備的輸出,導致電網電壓波動,而且增加了功率損耗。因此,在電力用戶中,提高(gao)功率因數(shu)并降(jiang)低(di)無功功率消耗對于節約能源和降低能耗具有重要意義。
無功補償的方法通常是:在變壓器的次級和負載中并聯電容器,因(yin)為該電容(rong)(rong)(rong)器(qi)是(shi)電容(rong)(rong)(rong)性的,它可以在系統(tong)中提(ti)供(gong)無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率,也就是(shi)說,該電容(rong)(rong)(rong)器(qi)用(yong)于提(ti)供(gong)無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率以減少(shao)所(suo)提(ti)供(gong)的無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率。因(yin)此(ci),無(wu)功(gong)(gong)(gong)補償是(shi)為了(le)減少(shao)無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率在視在功(gong)(gong)(gong)率中的比例(li)。
希(xi)拓電(dian)氣德國原裝進口低壓并聯電力電容器采(cai)用(yong)金屬化聚丙烯薄(bo)膜卷制而成,特殊噴金工藝,圓(yuan)柱型鋁外殼結構,保(bao)證性能和質量(liang)的穩定。在(zai)電(dian)力系統中能提高有效功率,降低無功損耗,進行無功補償,節約電力能源。根據場合不同又分為單相電(dian)容器和三(san)相電(dian)容器。如(ru)有(you)相關需求(qiu),歡(huan)迎來電(dian)咨詢!
