山西配電柜為什么要進行電容補償？看這里

配(pei)(pei)(pei)(pei)(pei)電柜分動(dong)力配(pei)(pei)(pei)(pei)(pei)電柜和照明(ming)配(pei)(pei)(pei)(pei)(pei)電柜、計(ji)量柜，是配(pei)(pei)(pei)(pei)(pei)電系統的(de)末級設(she)備(bei)，這級設(she)備(bei)應對負(fu)荷(he)提供(gong)保護(hu)、監視(shi)和控制。山(shan)西配(pei)(pei)(pei)(pei)(pei)電柜為(wei)什么要進行電容補償(chang)？小編為(wei)您介紹：

1、什么是(shi)(shi)電(dian)容補償(chang)(chang)呢?指的是(shi)(shi)無(wu)功(gong)補償(chang)(chang)或者(zhe)功(gong)率因數補償(chang)(chang)，電(dian)力系統的用(yong)電(dian)設(she)備在使(shi)用(yong)時會產生(sheng)無(wu)功(gong)功(gong)率，而且通常是(shi)(shi)電(dian)感性(xing)的。它會使(shi)電(dian)源的容量使(shi)用(yong)效率降低，而通過在系統中(zhong)適當地增加(jia)電(dian)容的方(fang)式就可(ke)以(yi)得以(yi)改善(shan)。

2、方(fang)法：并聯電(dian)(dian)容(rong)器，產生電(dian)(dian)容(rong)電(dian)(dian)流(liu)抵消電(dian)(dian)感電(dian)(dian)流(liu)，將不(bu)做功的所謂無(wu)功電(dian)(dian)流(liu)減(jian)小到一些范圍(wei)以內。無(wu)功電源同(tong)有功電源一樣，是保證(zheng)電能質量重要的一部分，在電力(li)系統中應(ying)保持(chi)無(wu)功平(ping)衡。

3、電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)補償(chang)(chang)作(zuo)用：配(pei)電(dian)(dian)(dian)(dian)柜電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)補償(chang)(chang)的(de)(de)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)和(he)負載是(shi)并聯(lian)連接的(de)(de)，電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)就(jiu)(jiu)和(he)電(dian)(dian)(dian)(dian)庫一樣(yang)。當負載增大時，由(you)于電(dian)(dian)(dian)(dian)源(yuan)存在內(nei)阻，電(dian)(dian)(dian)(dian)源(yuan)輸出(chu)電(dian)(dian)(dian)(dian)壓就(jiu)(jiu)會下降。由(you)于電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)的(de)(de)兩端要(yao)維持原(yuan)來的(de)(de)電(dian)(dian)(dian)(dian)壓，也就(jiu)(jiu)是(shi)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)內(nei)的(de)(de)電(dian)(dian)(dian)(dian)量要(yao)流出(chu)一部分(fen)，延緩(huan)了電(dian)(dian)(dian)(dian)壓的(de)(de)下降趨(qu)勢(shi)。
