安全補(bu)(bu)(bu)償中(zhong)有分相補(bu)(bu)(bu)償和(he)三(san)(san)相共補(bu)(bu)(bu)兩(liang)種方(fang)式，前(qian)者是采用(yong)單(dan)相電(dian)容(rong)器(qi)進(jin)行單(dan)相補(bu)(bu)(bu)償，而(er)后者是三(san)(san)相電(dian)容(rong)器(qi)同時補(bu)(bu)(bu)償。通常情況下，只有存在三(san)(san)相不平衡(heng)的(de)(de)系統(tong)中(zhong)才需(xu)要進(jin)行分相補(bu)(bu)(bu)償；而(er)一(yi)般的(de)(de)單(dan)相系統(tong)，如果負(fu)載不存在三(san)(san)相不平衡(heng)用(yong)共補(bu)(bu)(bu)就(jiu)可(ke)以(yi)了。

安裝補(bu)償(chang)模組解決方(fang)案

交(jiao)流(liu)電(dian)源所(suo)能(neng)提供的(de)(de)總功(gong)(gong)(gong)率(lv)(lv)(lv)，稱(cheng)之為(wei)(wei)“視(shi)在(zai)(zai)功(gong)(gong)(gong)率(lv)(lv)(lv)”或(huo)“表現功(gong)(gong)(gong)率(lv)(lv)(lv)”，在(zai)(zai)數(shu)值(zhi)上是(shi)交(jiao)流(liu)電(dian)路中電(dian)壓(ya)與電(dian)流(liu)的(de)(de)乘(cheng)積。視(shi)在(zai)(zai)功(gong)(gong)(gong)率(lv)(lv)(lv)用字母S表示，即S=U×I，單位是(shi)伏安（VA）或(huo)千伏安（KVA）。它通(tong)常(chang)用來表示交(jiao)流(liu)電(dian)源設備（如變壓(ya)器）的(de)(de)容量(liang)大小。視(shi)在(zai)(zai)功(gong)(gong)(gong)率(lv)(lv)(lv)既(ji)不等(deng)(deng)于(yu)有(you)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)，也不等(deng)(deng)于(yu)無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)，但它既(ji)包(bao)含有(you)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)又包(bao)含無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)。能(neng)否使視(shi)在(zai)(zai)功(gong)(gong)(gong)率(lv)(lv)(lv)為(wei)(wei)800KVA的(de)(de)變壓(ya)器輸出(chu)800KW的(de)(de)有(you)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)(lv)，主(zhu)要取決于(yu)負載(zai)的(de)(de)功(gong)(gong)(gong)率(lv)(lv)(lv)因數(shu)。

除此之(zhi)外，還(huan)有(you)一個諧(xie)波治理的重要手(shou)段，那就(jiu)是采(cai)用(yong)EMI電(dian)源濾波器。將其(qi)串聯或是并(bing)聯于主電(dian)路中，實時(shi)從補(bu)償對(dui)象中檢測出(chu)變頻(pin)器諧(xie)波電(dian)流，由補(bu)償裝置產生一個與該變頻(pin)器諧(xie)波電(dian)流大小(xiao)相(xiang)等、方向相(xiang)反的補(bu)償電(dian)流，從而使電(dian)網電(dian)流只含基(ji)波電(dian)流。
