       高壓電解電容通(tong)(tong)常是直(zhi)流電(dian)容器，但現(xian)在現(xian)已(yi)從(cong)(cong)直(zhi)流發(fa)展(zhan)到(dao)溝通(tong)(tong)、從(cong)(cong)低溫(wen)發(fa)展(zhan)到(dao)高溫(wen)、從(cong)(cong)通(tong)(tong)用(yong)型(xing)發(fa)展(zhan)到(dao)特別(bie)型(xing)、從(cong)(cong)通(tong)(tong)常構(gou)造發(fa)展(zhan)到(dao)片式、扁平、書(shu)本(ben)式等構(gou)造。其(qi)上限容量已(yi)擴展(zhan)到(dao)4f左(zuo)右，運(yun)用(yong)頻率(lv)已(yi)達到(dao)30khz，工作溫(wen)度(du)規模(mo)已(yi)達到(dao)-55℃—125℃，有的甚至高到(dao)150℃，額外電(dian)壓己達到(dao)700v。當然商品越多選(xuan)(xuan)擇也就越多，為您如何選(xuan)(xuan)用(yong)高壓電(dian)解電(dian)容呢？

　　高壓電(dian)容如何選擇(ze)

 　　1.要盡也(ye)許地選用原型號高(gao)壓電(dian)解電(dian)容。

　　2.通(tong)常(chang)(chang)高壓電(dian)(dian)解(jie)電(dian)(dian)容的(de)電(dian)(dian)容差錯大些，不會嚴重影(ying)響電(dian)(dian)路(lu)的(de)正常(chang)(chang)作業，所以可以取電(dian)(dian)容量(liang)略(lve)大一些或略(lve)小一些的(de)電(dian)(dian)容器替(ti)代。但在(zai)分(fen)頻電(dian)(dian)路(lu)、ｓ校對電(dian)(dian)路(lu)、振動回路(lu)及回路(lu)中不可，電(dian)(dian)容量(liang)應和核算(suan)請(qing)求的(de)盡量(liang)共同。在(zai)一些濾(lv)波網絡中，黑金剛電(dian)(dian)解(jie)電(dian)(dian)容，電(dian)(dian)解(jie)電(dian)(dian)容的(de)容量(liang)也請(qing)求非常(chang)(chang)，其(qi)差錯應小于(yu)±0.3－0.5。

　　3.耐(nai)壓請求必須滿意，選用的耐(nai)壓值應等于或(huo)大于原來的值。

　　4.通常運用無極(ji)性電解電容替代(dai)，真(zhen)實無辦法(fa)時(shi)可用兩只容量大一倍的(de)有極(ji)性電容逆串聯后替代(dai)，方法(fa)是(shi)將兩只要極(ji)性電解電容的(de)正極(ji)相(xiang)(xiang)連(lian)（或將它們(men)的(de)兩個負極(ji)相(xiang)(xiang)連(lian)）。

　　5.在選(xuan)用高(gao)(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)解電(dian)(dian)(dian)容時(shi)(shi)，選(xuan)用耐高(gao)(gao)(gao)溫(wen)的高(gao)(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)解電(dian)(dian)(dian)容，耐高(gao)(gao)(gao)溫(wen)電(dian)(dian)(dian)容的高(gao)(gao)(gao)作業(ye)溫(wen)度為105℃，當其(qi)(qi)在高(gao)(gao)(gao)作業(ye)溫(wen)度條件下作業(ye)時(shi)(shi)，能確保2000小(xiao)時(shi)(shi)左右的正常(chang)作業(ye)時(shi)(shi)間。在50℃下運用80℃的電(dian)(dian)(dian)容時(shi)(shi)，其(qi)(qi)壽(shou)數(shu)(shu)可達2.2萬小(xiao)時(shi)(shi)，假(jia)如此(ci)刻運用高(gao)(gao)(gao)溫(wen)高(gao)(gao)(gao)壓(ya)(ya)電(dian)(dian)(dian)解電(dian)(dian)(dian)容，其(qi)(qi)壽(shou)數(shu)(shu)可達9萬小(xiao)時(shi)(shi)。
