由于(yu)電(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)是用晶(jing)(jing)(jing)閘(zha)管控(kong)制(zhi)的(de)，其感(gan)(gan)性(xing)無功電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)可以變化，當(dang)晶(jing)(jing)(jing)閘(zha)管關斷(duan)時，電(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)沒有電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，而電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)固(gu)定連接，因此(ci)整(zheng)套裝置(zhi)的(de)補(bu)償(chang)(chang)量 大，當(dang)調(diao)節晶(jing)(jing)(jing)閘(zha)管的(de)導通角時，電(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)的(de)感(gan)(gan)性(xing)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)就(jiu)會(hui)抵消(xiao)一部(bu)分電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，因此(ci)補(bu)償(chang)(chang)量減少，導通角越大，電(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)越大，補(bu)償(chang)(chang)量就(jiu)越小，當(dang)晶(jing)(jing)(jing)閘(zha)管全通時，電(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)就(jiu)會(hui)將電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)全部(bu)抵消(xiao)，此(ci)時補(bu)償(chang)(chang)量為0。必須將固(gu)定電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)組設計成濾波器(qi)(qi)形式或(huo)者配備(bei)另外的(de)濾波器(qi)(qi)。

智能化低壓綜合(he)配(pei)電(dian)(dian)(dian)箱(xiang)（JP柜(ju)）PDJP-0.4 計量型低壓無(wu)功補償綜合(he)配(pei)電(dian)(dian)(dian)箱(xiang)  智能化低壓綜合(he)配(pei)電(dian)(dian)(dian)箱(xiang)（JP柜(ju)）公用變臺(tai)智能化低壓綜合(he)配(pei)電(dian)(dian)(dian)箱(xiang)（JP柜(ju)）適用于廣(guang)大(da)農村配(pei)電(dian)(dian)(dian)變壓器，額(e)(e)定(ding)(ding)頻率交流50Hz，額(e)(e)定(ding)(ding)工作電(dian)(dian)(dian)壓400V，額(e)(e)定(ding)(ding)電(dian)(dian)(dian)流630A及以下(xia)的配(pei)電(dian)(dian)(dian)系(xi)統(tong)中，戶外柱(zhu)上安裝使用。

封閉(bi)垂(chui)直分支(zhi)(zhi)母線式(shi)電(dian)(dian)容柜(ju)(ju)的面世，真正的解決了二次線纜困擾的巨大難題！低壓電(dian)(dian)容柜(ju)(ju)安裝在(zai)變壓器出口側，如(ru)電(dian)(dian)容柜(ju)(ju)各分支(zhi)(zhi)回路(lu)發生短路(lu)，相(xiang)當于(yu)變壓器出口短路(lu)，短路(lu)電(dian)(dian)流相(xiang)當大，可(ke)達20kA以上，如(ru)電(dian)(dian)容柜(ju)(ju)各支(zhi)(zhi)路(lu)采用微型(xing)斷路(lu)器作為(wei)短路(lu)保(bao)護是不科學的。
