山西配電柜為什么要進行電容補償？看這里

配(pei)電(dian)柜分動力配(pei)電(dian)柜和照明配(pei)電(dian)柜、計量柜，是配(pei)電(dian)系統的末級(ji)設備(bei)(bei)，這級(ji)設備(bei)(bei)應對負荷提供保護、監(jian)視和控制。山西配(pei)電(dian)柜為(wei)什(shen)么要進行電(dian)容補(bu)償？小編為(wei)您介紹(shao)：

1、什么是(shi)電容補(bu)(bu)償呢(ni)?指的(de)(de)是(shi)無功補(bu)(bu)償或者(zhe)功率因數補(bu)(bu)償，電力系統(tong)(tong)的(de)(de)用(yong)電設備(bei)在使用(yong)時會產(chan)生(sheng)無功功率，而且通常是(shi)電感性的(de)(de)。它會使電源的(de)(de)容量使用(yong)效率降低，而通過在系統(tong)(tong)中適當地(di)增加電容的(de)(de)方式就可以得以改善(shan)。

2、方(fang)法：并聯電(dian)(dian)容器，產生電(dian)(dian)容電(dian)(dian)流抵消電(dian)(dian)感(gan)電(dian)(dian)流，將不做功的所謂無功電(dian)(dian)流減小(xiao)到一些范圍以內(nei)。無功電源同有功電源一樣，是(shi)保(bao)證(zheng)電能質量(liang)重要的(de)一部(bu)分，在電力系統(tong)中應(ying)保(bao)持無功平衡。

3、電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)補償(chang)作用：配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)補償(chang)的電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)和負(fu)載是并聯連接(jie)的，電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)就(jiu)和電(dian)(dian)(dian)(dian)(dian)(dian)庫一樣。當負(fu)載增(zeng)大時，由于電(dian)(dian)(dian)(dian)(dian)(dian)源存在內阻(zu)，電(dian)(dian)(dian)(dian)(dian)(dian)源輸出電(dian)(dian)(dian)(dian)(dian)(dian)壓就(jiu)會下降(jiang)。由于電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的兩端要維持原來的電(dian)(dian)(dian)(dian)(dian)(dian)壓，也就(jiu)是電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)內的電(dian)(dian)(dian)(dian)(dian)(dian)量要流出一部分，延緩了電(dian)(dian)(dian)(dian)(dian)(dian)壓的下降(jiang)趨勢。
