智能建筑中(zhong)補(bu)償模組的主要(yao)作(zuo)用(yong)

無(wu)(wu)功倒送(song)問題。無(wu)(wu)功倒送(song)會(hui)增加線路和(he)變壓器的(de)損耗，加重線路供(gong)電負擔。固定補償部分容(rong)量過大，也容(rong)易出現無(wu)(wu)功倒送(song)。 三(san)(san)相不平衡問題。系統三(san)(san)相不平衡同樣會(hui)增大線路和(he)變壓器的(de)損耗。對三(san)(san)相不平衡較大的(de)負荷，比如機關、學校等單(dan)相負荷多(duo)的(de)用戶(hu)，應考慮采用分相無(wu)(wu)功補償裝置(zhi)。
