  大功率穿心電容是由兩個電極及其間的介電材料構成的。介電材料是一種電介質，當被置于兩塊帶有等量異性電荷的平行極板間的電場中時，由于極化而在介質表面產生極化電荷，遂使束縛在極板上的電荷相應增加，維持極板間的電位差不變。大(da)功率(lv)穿心電容器有(you)限公司專業致力于大(da)功率(lv)穿心電容器行業的大(da)功率(lv)穿心電容器生(sheng)產廠家

  大(da)功(gong)率(lv)(lv)穿(chuan)心電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)是(shi)由兩(liang)個電(dian)(dian)(dian)(dian)極(ji)及其(qi)間的(de)介(jie)電(dian)(dian)(dian)(dian)材料(liao)構成的(de)。介(jie)電(dian)(dian)(dian)(dian)材料(liao)是(shi)一(yi)種電(dian)(dian)(dian)(dian)介(jie)質(zhi)，當被置于兩(liang)塊帶有(you)等量(liang)(liang)異性電(dian)(dian)(dian)(dian)荷的(de)平行極(ji)板間的(de)電(dian)(dian)(dian)(dian)場中(zhong)時，由于極(ji)化(hua)而在介(jie)質(zhi)表(biao)面產生極(ji)化(hua)電(dian)(dian)(dian)(dian)荷，遂(sui)使束縛在極(ji)板上的(de)電(dian)(dian)(dian)(dian)荷相應增加，維持極(ji)板間的(de)電(dian)(dian)(dian)(dian)位差(cha)不(bu)變。這就是(shi)大(da)功(gong)率(lv)(lv)穿(chuan)心電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)具(ju)有(you)大(da)功(gong)率(lv)(lv)穿(chuan)心電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)特征的(de)原因。大(da)功(gong)率(lv)(lv)穿(chuan)心電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)中(zhong)儲存的(de)電(dian)(dian)(dian)(dian)量(liang)(liang)Q等于大(da)功(gong)率(lv)(lv)穿(chuan)心電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)量(liang)(liang)C與(yu)電(dian)(dian)(dian)(dian)極(ji)間的(de)電(dian)(dian)(dian)(dian)位差(cha)U 的(de)乘積(ji)。大(da)功(gong)率(lv)(lv)穿(chuan)心電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)量(liang)(liang)與(yu)極(ji)板面積(ji)和(he)介(jie)電(dian)(dian)(dian)(dian)材料(liao)的(de)介(jie)電(dian)(dian)(dian)(dian)常數 ε成正比，與(yu)介(jie)電(dian)(dian)(dian)(dian)材料(liao)厚(hou)度（即極(ji)板間的(de)距離）成反比。

  放電使充電后的(de)大(da)功率穿(chuan)(chuan)心電容(rong)器失(shi)去電荷(he)（釋放電荷(he)和電能）的(de)過(guo)程稱為(wei)放電。例如(ru)，用一(yi)根(gen)導線把大(da)功率穿(chuan)(chuan)心電容(rong)器的(de)兩(liang)極(ji)接通，兩(liang)極(ji)上的(de)電荷(he)互相中和，大(da)功率穿(chuan)(chuan)心電容(rong)器就會放出電荷(he)和電能。放電后大(da)功率穿(chuan)(chuan)心電容(rong)器的(de)兩(liang)極(ji)板之間的(de)電場消(xiao)失(shi)，電能轉化為(wei)其它形(xing)式的(de)能。
