在(zai)電(dian)(dian)氣自動化(hua)中運用無(wu)功(gong)補償技術，能(neng)有(you)效地降低無(wu)功(gong)功(gong)率(lv)，從另一(yi)個側面也(ye)就提(ti)升了有(you)功(gong)功(gong)率(lv)。在(zai)對有(you)功(gong)功(gong)率(lv)數(shu)值需求(qiu)不(bu)變的情況(kuang)下，可以通過減少無(wu)功(gong)功(gong)率(lv)、供(gong)電(dian)(dian)設(she)備配電(dian)(dian)電(dian)(dian)容的數(shu)量和規(gui)模，提(ti)升設(she)備的發(fa)(fa)供(gong)電(dian)(dian)能(neng)力，挖掘(jue)設(she)備發(fa)(fa)供(gong)電(dian)(dian)潛能(neng)。

純電容無功補償柜的主要(yao)作用

在一定的(de)有(you)功(gong)(gong)功(gong)(gong)率下，功(gong)(gong)率因數越(yue)(yue)小，所需的(de)無(wu)功(gong)(gong)功(gong)(gong)率越(yue)(yue)大(da)。為滿(man)足用(yong)(yong)(yong)電(dian)的(de)需求，供電(dian)線(xian)(xian)路(lu)和變壓(ya)器(qi)的(de)容(rong)量就需要(yao)(yao)增加，這樣(yang)不僅要(yao)(yao)增加供電(dian)投資、降低(di)設備利用(yong)(yong)(yong)率，也將增加線(xian)(xian)路(lu)損(sun)耗。為了提高電(dian)網(wang)的(de)經濟運(yun)行效(xiao)率，根據(ju)電(dian)網(wang)中的(de)無(wu)功(gong)(gong)類型，人(ren)為的(de)補償(chang)容(rong)性無(wu)功(gong)(gong)或感性無(wu)功(gong)(gong)來抵消線(xian)(xian)路(lu)的(de)無(wu)功(gong)(gong)功(gong)(gong)率，這就是無(wu)功(gong)(gong)補償(chang)柜的(de)主(zhu)要(yao)(yao)用(yong)(yong)(yong)途(tu)。

較低電(dian)壓(ya)等級的(de)電(dian)容器(qi)經串聯后運行于較高電(dian)壓(ya)等級網絡中(zhong)時，其(qi)各臺的(de)外殼(ke)(ke)對(dui)地之間，應通過加裝相當(dang)于運行電(dian)壓(ya)等級的(de)絕緣(yuan)子等措施，使之可靠絕緣(yuan)。電(dian)容器(qi)經星形(xing)連接(jie)后，用于高一級額定電(dian)壓(ya)，且系中(zhong)性點不接(jie)地時，電(dian)容器(qi)的(de)外殼(ke)(ke)應對(dui)地絕緣(yuan)。
