原來日常用(yong)電(dian)(dian)(dian)設(she)備中除了電(dian)(dian)(dian)阻性負(fu)載(zai)，大(da)部分是感性負(fu)載(zai)，像(xiang)日光燈、變(bian)(bian)壓器、發動(dong)機等。這些(xie)感性負(fu)載(zai)，使電(dian)(dian)(dian)源相位發生變(bian)(bian)化，導致(zhi)電(dian)(dian)(dian)壓波(bo)動(dong)大(da)，無功(gong)(gong)功(gong)(gong)率增大(da)，浪(lang)費電(dian)(dian)(dian)能(neng)。而(er)通(tong)過電(dian)(dian)(dian)容(rong)(rong)補(bu)(bu)(bu)償(chang)柜進行無功(gong)(gong)因素的補(bu)(bu)(bu)償(chang)，可(ke)以有效(xiao)的解決這個問(wen)題，提供(gong)供(gong)電(dian)(dian)(dian)效(xiao)率。電(dian)(dian)(dian)容(rong)(rong)補(bu)(bu)(bu)償(chang)柜的自動(dong)補(bu)(bu)(bu)償(chang)裝置(zhi)可(ke)以根據用(yong)電(dian)(dian)(dian)負(fu)荷的變(bian)(bian)化，自動(dong)設(she)置(zhi)電(dian)(dian)(dian)容(rong)(rong)組(zu)數的投入，減低大(da)量無功(gong)(gong)電(dian)(dian)(dian)流(liu)，從而(er)減少無功(gong)(gong)用(yong)電(dian)(dian)(dian)。

電容柜的(de)原理

低(di)壓電(dian)容(rong)(rong)柜中的(de)電(dian)容(rong)(rong)器是(shi)容(rong)(rong)性負(fu)荷(he)的(de)裝置(zhi)，與感性負(fu)荷(he)的(de)裝置(zhi)連接在同一電(dian)路中，當(dang)容(rong)(rong)性負(fu)荷(he)釋放能(neng)(neng)(neng)量時，感性負(fu)荷(he)吸收能(neng)(neng)(neng)量，當(dang)感性負(fu)荷(he)釋放能(neng)(neng)(neng)量時，容(rong)(rong)性負(fu)荷(he)吸收能(neng)(neng)(neng)量，能(neng)(neng)(neng)量在兩者之間轉(zhuan)換。這(zhe)樣感性負(fu)荷(he)吸收的(de)無功(gong)功(gong)率(lv)可由容(rong)(rong)性負(fu)荷(he)輸出的(de)無功(gong)功(gong)率(lv)得到(dao)補償(chang)(chang)，從而將控制因(yin)素控制在0.9以上。這(zhe)就是(shi)電(dian)容(rong)(rong)柜的(de)補償(chang)(chang)原理。
