智(zhi)能電(dian)(dian)(dian)容器(qi)集成(cheng)了現代(dai)測控(kong)，電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)子，網絡通訊，自動化控(kong)制(zhi)，電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)容器(qi)等(deng)先進技術。改變了傳(chuan)統(tong)(tong)無(wu)功(gong)(gong)補(bu)(bu)償裝置落后的(de)控(kong)制(zhi)器(qi)技術和落后的(de)機(ji)械式接觸器(qi)或機(ji)電(dian)(dian)(dian)一(yi)體(ti)化開關作為投(tou)切(qie)電(dian)(dian)(dian)容器(qi)的(de)投(tou)切(qie)技術，改變了傳(chuan)統(tong)(tong)無(wu)功(gong)(gong)補(bu)(bu)償裝置體(ti)積龐大和笨重(zhong)的(de)結構模式，從而使新一(yi)代(dai)低(di)壓(ya)無(wu)功(gong)(gong)補(bu)(bu)償設備具(ju)有補(bu)(bu)償效果更(geng)好，體(ti)積更(geng)小，功(gong)(gong)耗更(geng)低(di)，價(jia)格更(geng)廉，節約成(cheng)本更(geng)多，使用(yong)更(geng)加(jia)靈活，維護更(geng)加(jia)方便(bian)，使用(yong)壽命更(geng)長，可(ke)靠性更(geng)高(gao)的(de)特點，適應了現代(dai)電(dian)(dian)(dian)網對無(wu)功(gong)(gong)補(bu)(bu)償的(de)更(geng)高(gao)要求(qiu)。

純電(dian)容無功補(bu)償(chang)在電(dian)力系統(tong)的(de)作用(yong)和結(jie)構

電(dian)(dian)(dian)容補(bu)償(chang)(chang)的(de)(de)常用(yong)方(fang)式分為以下(xia)幾(ji)種(zhong)(zhong)，每種(zhong)(zhong)補(bu)償(chang)(chang)方(fang)式都有各自的(de)(de)優劣(lie)勢：（1）集中(zhong)補(bu)償(chang)(chang)：在高低(di)壓配電(dian)(dian)(dian)線路中(zhong)安(an)(an)裝并(bing)聯電(dian)(dian)(dian)容器組(zu)；（2）分組(zu)補(bu)償(chang)(chang)：在配電(dian)(dian)(dian)變壓器低(di)壓側和用(yong)戶車間(jian)配電(dian)(dian)(dian)屏安(an)(an)裝并(bing)聯補(bu)償(chang)(chang)電(dian)(dian)(dian)容器；（3）單臺電(dian)(dian)(dian)動機就地補(bu)償(chang)(chang)：在單臺電(dian)(dian)(dian)動機處安(an)(an)裝并(bing)聯電(dian)(dian)(dian)容器等。加裝無功(gong)補(bu)償(chang)(chang)設備，不僅可使功(gong)率(lv)消耗(hao)小，功(gong)率(lv)因數提(ti)高，還可以充分挖掘(jue)設備輸送功(gong)率(lv)的(de)(de)潛力。

微型(xing)斷(duan)(duan)路(lu)(lu)器(qi)一般(ban)(ban)額定電(dian)流(liu)為 63A，似(si)乎用于400V ，30Kvar電(dian)容(rong)器(qi)保(bao)護沒有問題(ti)，但(dan)它的(de)(de)斷(duan)(duan)流(liu)能(neng)(neng)力不(bu)足。一般(ban)(ban)電(dian)容(rong)器(qi)補償柜(ju)安裝在低壓總(zong)開關柜(ju)附近，短(duan)路(lu)(lu)電(dian)流(liu)非常大，往往達到30kA以上(shang)，而微型(xing)斷(duan)(duan)路(lu)(lu)器(qi)開斷(duan)(duan)能(neng)(neng)力一般(ban)(ban)不(bu)超(chao)過10kA,如(ru)果(guo)改(gai)用塑殼斷(duan)(duan)路(lu)(lu)器(qi)，造(zao)成投(tou)資的(de)(de)增加及安裝空間的(de)(de)增大，而且斷(duan)(duan)路(lu)(lu)器(qi)的(de)(de)過載保(bao)護功能(neng)(neng)也不(bu)需(xu)要。因此，采用熔斷(duan)(duan)器(qi)作為回(hui)路(lu)(lu)保(bao)護元件是合適的(de)(de)。
