低(di)壓無(wu)(wu)(wu)功(gong)(gong)(gong)補(bu)(bu)(bu)償柜(ju)是(shi)用(yong)于補(bu)(bu)(bu)償低(di)壓電(dian)網(wang)(wang)(wang)的(de)(de)無(wu)(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)，從而提高電(dian)網(wang)(wang)(wang)的(de)(de)功(gong)(gong)(gong)率(lv)因數(shu)，減少線損，改善電(dian)網(wang)(wang)(wang)的(de)(de)電(dian)能質量。該(gai)系(xi)列低(di)壓無(wu)(wu)(wu)功(gong)(gong)(gong)補(bu)(bu)(bu)償柜(ju)以(yi)智(zhi)能無(wu)(wu)(wu)功(gong)(gong)(gong)率(lv)控(kong)制器(qi)(qi)為(wei)核心，利(li)用(yong)容(rong)器(qi)(qi)作為(wei)電(dian)容(rong)組的(de)(de)切割器(qi)(qi)，并根(gen)(gen)據電(dian)網(wang)(wang)(wang)功(gong)(gong)(gong)率(lv)自動切割容(rong)器(qi)(qi)，以(yi)確保電(dian)網(wang)(wang)(wang)始終具(ju)有(you)較高的(de)(de)功(gong)(gong)(gong)率(lv)因素(su)。低(di)壓無(wu)(wu)(wu)功(gong)(gong)(gong)補(bu)(bu)(bu)償柜(ju)的(de)(de)補(bu)(bu)(bu)償元(yuan)件(jian)是(shi)電(dian)容(rong)器(qi)(qi)，可以(yi)用(yong)于低(di)諧(xie)波情況，低(di)壓無(wu)(wu)(wu)功(gong)(gong)(gong)補(bu)(bu)(bu)償柜(ju)的(de)(de)補(bu)(bu)(bu)償元(yuan)件(jian)是(shi)電(dian)容(rong)器(qi)(qi)，但可以(yi)根(gen)(gen)據各(ge)相的(de)(de)負載(zai)切斷，低(di)壓無(wu)(wu)(wu)功(gong)(gong)(gong)補(bu)(bu)(bu)償柜(ju)的(de)(de)補(bu)(bu)(bu)償元(yuan)件(jian)是(shi)由電(dian)容(rong)器(qi)(qi)和電(dian)抗器(qi)(qi)串聯組成，具(ju)有(you)抑制諧(xie)波的(de)(de)功(gong)(gong)(gong)能。

首次裝置無功補償元件優(you)缺點分(fen)析

新購置(zhi)的(de)(de)低壓無功(gong)補(bu)償(chang)裝(zhuang)置(zhi)柜，由于生產廠家(jia)的(de)(de)不(bu)(bu)同，在(zai)安裝(zhuang)電(dian)源線(xian)的(de)(de)接線(xian)方法上也不(bu)(bu)相同，主要(yao)與廠家(jia)在(zai)低壓無功(gong)補(bu)償(chang)裝(zhuang)置(zhi)柜上配置(zhi)的(de)(de)無功(gong)功(gong)率自動補(bu)償(chang)控制器JKG系列（簡稱(cheng)：控制器）的(de)(de)取樣(yang)檢測信號電(dian)源有(you)關(guan)，有(you)的(de)(de)儀器的(de)(de)取樣(yang)電(dian)流(liu)和取樣(yang)電(dian)壓要(yao)同相，有(you)的(de)(de)是不(bu)(bu)要(yao)求同相。

另一方面，由于(yu)極薄(bo)的(de)(de)鋁膜(mo)極板并(bing)沒有多少機械強度，因(yin)此芯元(yuan)件端部導(dao)電(dian)層與極板之間(jian)并(bing)不能形成牢固的(de)(de)連接，當芯元(yuan)件由于(yu)發熱而出現不均勻變形時(shi)，端部導(dao)電(dian)層與極板之間(jian)很容易(yi)形成局部脫(tuo)離而出現故(gu)障(zhang)，從這一點出發，又希(xi)望(wang)芯元(yuan)件盡量卷制成細長形。
