純電容低壓(ya)補償模組不補償的(de)原因

嚴禁電(dian)容(rong)器組(zu)帶電(dian)荷合(he)(he)閘。如果合(he)(he)閘瞬(shun)間電(dian)壓極(ji)性(xing)正(zheng)好和電(dian)容(rong)器上殘留(liu)電(dian)荷的極(ji)性(xing)相反(fan)，兩電(dian)壓相加(jia)將在(zai)回路(lu)上產生很大(da)的沖擊(ji)電(dian)流，引起過熱(re)爆炸。所以(yi)，電(dian)容(rong)器組(zu)每次重新(xin)合(he)(he)閘，必(bi)須在(zai)斷路(lu)器斷開電(dian)容(rong)器組(zu)放電(dian)5分鐘后進行(xing)。

相位(wei)差賠(pei)(pei)償(chang)是以(yi)進(jin)相的無(wu)功(gong)(gong)補(bu)償(chang)機器設備（如串(chuan)聯電(dian)力電(dian)容器）原則提(ti)供客戶或配電(dian)網所(suo)必(bi)須的滯(zhi)相無(wu)功(gong)(gong)負荷，降低在配電(dian)網中流動性的無(wu)功(gong)(gong)負荷，減少網損，改進(jin)電(dian)壓品質。我國對大(da)電(dian)力工程客戶規定安(an)裝無(wu)功(gong)(gong)補(bu)償(chang)設備，賠(pei)(pei)償(chang)后的功(gong)(gong)率(lv)因素不可小于0.9。
