山西配電柜為什么要進行電容補償？看這里

配(pei)電(dian)柜(ju)分動(dong)力配(pei)電(dian)柜(ju)和照(zhao)明配(pei)電(dian)柜(ju)、計(ji)量(liang)柜(ju)，是配(pei)電(dian)系統的末級設備，這級設備應對負荷(he)提供(gong)保(bao)護(hu)、監視和控制。山西配(pei)電(dian)柜(ju)為什么要進行電(dian)容補(bu)償？小編為您(nin)介(jie)紹：

1、什么是(shi)電(dian)容(rong)補(bu)償呢?指(zhi)的是(shi)無(wu)功(gong)補(bu)償或者功(gong)率因數(shu)補(bu)償，電(dian)力系統的用(yong)電(dian)設(she)備在(zai)使用(yong)時會產生無(wu)功(gong)功(gong)率，而且通常(chang)是(shi)電(dian)感性(xing)的。它(ta)會使電(dian)源的容(rong)量使用(yong)效率降低(di)，而通過在(zai)系統中適當地增加(jia)電(dian)容(rong)的方(fang)式就可以得以改善。

2、方法：并聯電容(rong)器，產生電容(rong)電流(liu)抵消電感電流(liu)，將不做(zuo)功(gong)的所(suo)謂無(wu)功(gong)電流(liu)減小到(dao)一些(xie)范(fan)圍以內。無(wu)功(gong)電(dian)源(yuan)同(tong)有功(gong)電(dian)源(yuan)一樣，是(shi)保證電(dian)能質量重要的一部分，在電(dian)力系統中應保持無(wu)功(gong)平衡。

3、電(dian)(dian)(dian)(dian)容補償(chang)(chang)作用：配電(dian)(dian)(dian)(dian)柜電(dian)(dian)(dian)(dian)容補償(chang)(chang)的電(dian)(dian)(dian)(dian)容和(he)負載(zai)是(shi)并聯(lian)連接的，電(dian)(dian)(dian)(dian)容就和(he)電(dian)(dian)(dian)(dian)庫一(yi)樣。當負載(zai)增大時，由于電(dian)(dian)(dian)(dian)源存在內(nei)阻(zu)，電(dian)(dian)(dian)(dian)源輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)就會下降(jiang)。由于電(dian)(dian)(dian)(dian)容的兩端要維持原來的電(dian)(dian)(dian)(dian)壓(ya)，也(ye)就是(shi)電(dian)(dian)(dian)(dian)容內(nei)的電(dian)(dian)(dian)(dian)量要流(liu)出(chu)一(yi)部(bu)分，延(yan)緩了電(dian)(dian)(dian)(dian)壓(ya)的下降(jiang)趨勢。
