大(da)家用的電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)容(rong)(rong)器和電(dian)(dian)(dian)(dian)抗器的型(xing)號(hao)匹配嗎(ma)?一個化工企業(ye)客戶說(shuo)最近電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)容(rong)(rong)器總是(shi)變形，并且功(gong)率因數一直不(bu)達標，電(dian)(dian)(dian)(dian)業(ye)局罰了很(hen)多(duo)錢原(yuan)因是(shi)什么呢?
客戶系統電壓為400V，采用的電力電容器的型號(hao)是BSMJ0.525-40-3，電(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)器(qi)(qi)(qi)型號(hao)卻是CGDL500/40/6-50，6%，400V 40kvar.電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)選(xuan)用525V 40kvar,電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)的實際輸出容(rong)量(liang)只有(you)20多kvar，電(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)器(qi)(qi)(qi)的輸出容(rong)量(liang)為(wei)30多kvar，電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)和(he)電(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)器(qi)(qi)(qi)參數嚴重不(bu)匹配(pei)容(rong)易產生諧(xie)振，導致(zhi)熔(rong)斷器(qi)(qi)(qi)燒毀(hui)，斷路器(qi)(qi)(qi)和(he)其他(ta)用電(dian)(dian)(dian)(dian)(dian)設備(bei)出現故障等。另外，系統(tong)電(dian)(dian)(dian)(dian)(dian)壓會有(you)偏(pian)差(cha)，高點時會在(zai)428V，系統(tong)里還會有(you)諧(xie)波電(dian)(dian)(dian)(dian)(dian)壓，電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)串連(lian)電(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)器(qi)(qi)(qi)后端電(dian)(dian)(dian)(dian)(dian)壓還會升高，建(jian)議更換匹配(pei)電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)和(he)電(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)(kang)器(qi)(qi)(qi)。
因為客戶是化工企業用電，諧波源主要是變頻器，根據客戶提供的測試數據分析，系統以5次，7次諧波為主，并且諧波含量不是很大，這種工況通常建議客戶選用480V電力電容器和電抗率7% 480V 電抗器。
