智能建筑中低壓補償(chang)模組解決方案

因為過補(bu)償(chang)要罰款，如果(guo)無功(gong)功(gong)率不穩定，且變化較(jiao)大，采用自(zi)動投切可(ke)獲(huo)得合理(li)的經濟效果(guo)時(shi)，宜(yi)裝設(she)無功(gong)自(zi)動補(bu)償(chang)裝置。由于高壓(ya)無功(gong)自(zi)動補(bu)償(chang)裝置對切換元件的要求(qiu)比較(jiao)高，且價格(ge)較(jiao)高，檢修維(wei)護也(ye)較(jiao)困難，因此(ci)當(dang)補(bu)償(chang)效果(guo)相同(tong)時(shi)，宜(yi)優先(xian)采用低壓(ya)無功(gong)自(zi)動補(bu)償(chang)裝置。

低壓(ya)(ya)分(fen)散(san)補(bu)償(chang)就是根據個(ge)別用(yong)(yong)電(dian)(dian)設(she)備(bei)對無(wu)功(gong)的(de)(de)需要量，將(jiang)單(dan)臺(tai)或多臺(tai)低壓(ya)(ya)電(dian)(dian)容(rong)器組，分(fen)散(san)地安裝(zhuang)在用(yong)(yong)電(dian)(dian)設(she)備(bei)附(fu)近，以(yi)補(bu)償(chang)安裝(zhuang)部位前(qian)邊的(de)(de)所有高低壓(ya)(ya)線路(lu)(lu)和變(bian)壓(ya)(ya)器的(de)(de)無(wu)功(gong)功(gong)率。其優點是用(yong)(yong)電(dian)(dian)設(she)備(bei)運(yun)行(xing)時，無(wu)功(gong)補(bu)償(chang)投入，用(yong)(yong)電(dian)(dian)設(she)備(bei)停運(yun)時，補(bu)償(chang)設(she)備(bei)也退出(chu)，可減(jian)少(shao)配電(dian)(dian)網和變(bian)壓(ya)(ya)器中的(de)(de)無(wu)功(gong)流(liu)動，從而減(jian)少(shao)有功(gong)損耗(hao)；可減(jian)少(shao)線路(lu)(lu)的(de)(de)導線截面及變(bian)壓(ya)(ya)器的(de)(de)容(rong)量,占(zhan)位小。缺(que)點是利用(yong)(yong)率低、投資大,對變(bian)速(su)運(yun)行(xing)，正(zheng)反(fan)向運(yun)行(xing)，點動、堵轉、反(fan)接制(zhi)動的(de)(de)電(dian)(dian)機則不適(shi)應。
