無功補償柜的(de)(de)(de)(de)作(zuo)(zuo)用(yong)就(jiu)是提高功率因數，降低線(xian)路的(de)(de)(de)(de)損耗(hao)，增(zeng)增(zeng)加變壓器(qi)的(de)(de)(de)(de)使用(yong)裕度。在電(dian)(dian)(dian)(dian)容器(qi)前端串聯電(dian)(dian)(dian)(dian)抗(kang)的(de)(de)(de)(de)作(zuo)(zuo)用(yong)是防止電(dian)(dian)(dian)(dian)容器(qi)和用(yong)電(dian)(dian)(dian)(dian)系統發生串、并聯諧振，導致諧波(bo)被(bei)放大，而使電(dian)(dian)(dian)(dian)容器(qi)過電(dian)(dian)(dian)(dian)流而損壞，其次的(de)(de)(de)(de)話串聯電(dian)(dian)(dian)(dian)抗(kang)器(qi)還可(ke)以(yi)起到限(xian)制(zhi)涌流的(de)(de)(de)(de)作(zuo)(zuo)用(yong)。如1%的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)抗(kang)器(qi)只是抑制(zhi)電(dian)(dian)(dian)(dian)容器(qi)合閘瞬間的(de)(de)(de)(de)涌流；6%電(dian)(dian)(dian)(dian)抗(kang)器(qi)是抑制(zhi)5次及以(yi)上諧波(bo)的(de)(de)(de)(de)。

電(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)(kang)(kang)器分兩種：限流(liu)電(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)(kang)(kang)和(he)諧(xie)波(bo)(bo)電(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)(kang)(kang)。過去都是用(yong)限流(liu)電(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)(kang)(kang)+普通接觸(chu)器，現(xian)在有(you)專門切換電(dian)(dian)(dian)(dian)容(rong)器的(de)接觸(chu)器了(le)，一般(ban)不再需要限流(liu)電(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)(kang)(kang)；當系統中諧(xie)波(bo)(bo)較大(da)時(shi)，應增加諧(xie)波(bo)(bo)電(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)(kang)(kang)，此(ci)時(shi)電(dian)(dian)(dian)(dian)容(rong)器要用(yong)消(xiao)諧(xie)電(dian)(dian)(dian)(dian)容(rong)器，組成(cheng)靜態補償和(he)濾除(chu)諧(xie)波(bo)(bo)裝置(zhi)(zhi)。一般(ban)為(wei)了(le)減(jian)小(xiao)響應時(shi)間，現(xian)在應考慮使用(yong)動態補償和(he)消(xiao)諧(xie)裝置(zhi)(zhi)。此(ci)外，當負(fu)荷(he)中諧(xie)波(bo)(bo)成(cheng)分較多的(de)時(shi)候(如(ru)帶有(you)電(dian)(dian)(dian)(dian)焊機，電(dian)(dian)(dian)(dian)爐(lu)等)就必須加濾波(bo)(bo)電(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)(kang)(kang)器，且(qie)濾波(bo)(bo)電(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)(kang)(kang)器要與系統中的(de)諧(xie)波(bo)(bo)次數相匹配(pei)(pei)(如(ru)主要為(wei)5、7次諧(xie)波(bo)(bo)的(de)話匹配(pei)(pei)6%的(de)電(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)(kang)(kang))。并且(qie)此(ci)時(shi)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)容(rong)器的(de)額定電(dian)(dian)(dian)(dian)壓要選高一等級。

電(dian)(dian)(dian)容(rong)補償柜中安(an)裝電(dian)(dian)(dian)抗器，有兩種目的(de)：1.限制電(dian)(dian)(dian)容(rong)投入(ru)時的(de)涌流。2.在存在大(da)量諧波電(dian)(dian)(dian)流的(de)系統中，串電(dian)(dian)(dian)抗器可以避免對諧波電(dian)(dian)(dian)流產生(sheng)諧振放大(da)，即所謂消諧式電(dian)(dian)(dian)容(rong)器。

安徽得潤電氣無功補償柜使(shi)用ABB電抗器，質量優，使(shi)用壽命長(chang)，高(gao)達(da)二(er)三十年(nian)，提(ti)高(gao)功率因數，降(jiang)低線路的(de)損耗，增加變壓器的(de)使(shi)用裕度。
