補(bu)償(chang)(chang)電(dian)(dian)容器組(zu)裝(zhuang)設在(zai)變電(dian)(dian)站站內母線上，可(ke)手動(dong)(dong)或分組(zu)自動(dong)(dong)補(bu)償(chang)(chang)。結合(he)電(dian)(dian)網(wang)實際情(qing)況，選擇按功率(lv)因數、電(dian)(dian)壓(ya)無(wu)功、電(dian)(dian)壓(ya)無(wu)功綜(zong)合(he)控(kong)制(zhi)(zhi)或電(dian)(dian)壓(ya)無(wu)功綜(zong)合(he)控(kong)制(zhi)(zhi)兼濾(lv)波等不同方式進行補(bu)償(chang)(chang)。動(dong)(dong)態(tai)無(wu)功補(bu)償(chang)(chang)由可(ke)控(kong)硅控(kong)制(zhi)(zhi)投(tou)切(qie)電(dian)(dian)容器，這種(zhong)控(kong)制(zhi)(zhi)方式反(fan)應速度一(yi)般(ban)在(zai)20ms，投(tou)切(qie)時無(wu)充電(dian)(dian)電(dian)(dian)流和過電(dian)(dian)壓(ya)，但由于(yu)可(ke)控(kong)硅有自然導(dao)通(tong)電(dian)(dian)壓(ya)的特性，電(dian)(dian)容器投(tou)切(qie)是會產生諧波。

純(chun)電容(rong)低壓補償(chang)模組不補償(chang)的原因

嚴(yan)禁電(dian)(dian)(dian)(dian)容(rong)器組(zu)(zu)帶電(dian)(dian)(dian)(dian)荷合(he)閘(zha)。如果合(he)閘(zha)瞬間(jian)電(dian)(dian)(dian)(dian)壓極性(xing)(xing)正好(hao)和電(dian)(dian)(dian)(dian)容(rong)器上殘留電(dian)(dian)(dian)(dian)荷的極性(xing)(xing)相反，兩電(dian)(dian)(dian)(dian)壓相加將在回路上產生很大的沖擊電(dian)(dian)(dian)(dian)流，引起過(guo)熱(re)爆炸。所以，電(dian)(dian)(dian)(dian)容(rong)器組(zu)(zu)每次重(zhong)新合(he)閘(zha)，必須在斷路器斷開(kai)電(dian)(dian)(dian)(dian)容(rong)器組(zu)(zu)放電(dian)(dian)(dian)(dian)5分鐘后進行。
