原來日常用(yong)電(dian)(dian)(dian)(dian)設(she)備(bei)中除了(le)電(dian)(dian)(dian)(dian)阻性(xing)負(fu)載(zai)(zai)(zai)，大部分是感性(xing)負(fu)載(zai)(zai)(zai)，像日光燈(deng)、變壓器、發動機(ji)等。這些感性(xing)負(fu)載(zai)(zai)(zai)，使電(dian)(dian)(dian)(dian)源相(xiang)位發生變化，導(dao)致電(dian)(dian)(dian)(dian)壓波(bo)動大，無(wu)功功率增(zeng)大，浪(lang)費電(dian)(dian)(dian)(dian)能(neng)。而通過電(dian)(dian)(dian)(dian)容(rong)補償(chang)柜進行(xing)無(wu)功因素的補償(chang)，可以(yi)有效的解決這個問題，提供供電(dian)(dian)(dian)(dian)效率。電(dian)(dian)(dian)(dian)容(rong)補償(chang)柜的自動補償(chang)裝置可以(yi)根(gen)據用(yong)電(dian)(dian)(dian)(dian)負(fu)荷的變化，自動設(she)置電(dian)(dian)(dian)(dian)容(rong)組數(shu)的投入，減低大量無(wu)功電(dian)(dian)(dian)(dian)流，從(cong)而減少無(wu)功用(yong)電(dian)(dian)(dian)(dian)。

電容柜(ju)的(de)原理

低壓(ya)電(dian)容柜(ju)中(zhong)的電(dian)容器是容性(xing)負(fu)荷(he)(he)的裝置，與感(gan)性(xing)負(fu)荷(he)(he)的裝置連(lian)接在同(tong)一電(dian)路中(zhong)，當(dang)容性(xing)負(fu)荷(he)(he)釋(shi)放能(neng)(neng)量(liang)(liang)時，感(gan)性(xing)負(fu)荷(he)(he)吸收(shou)(shou)能(neng)(neng)量(liang)(liang)，當(dang)感(gan)性(xing)負(fu)荷(he)(he)釋(shi)放能(neng)(neng)量(liang)(liang)時，容性(xing)負(fu)荷(he)(he)吸收(shou)(shou)能(neng)(neng)量(liang)(liang)，能(neng)(neng)量(liang)(liang)在兩者之(zhi)間轉(zhuan)換。這(zhe)樣感(gan)性(xing)負(fu)荷(he)(he)吸收(shou)(shou)的無功(gong)功(gong)率(lv)可由(you)容性(xing)負(fu)荷(he)(he)輸出的無功(gong)功(gong)率(lv)得(de)到補償，從(cong)而將(jiang)控制因素控制在0.9以上。這(zhe)就是電(dian)容柜(ju)的補償原理。
