電解(jie)電容(rong)，在(zai)充(chong)電電路中主要(yao)作用為儲(chu)能和濾波。PN端的(de)電壓工(gong)作范圍一般(ban)在(zai) 430VDC～700VDC 之間，而一般(ban)的(de)高壓電容(rong)都(dou)在(zai) 400VDC左右(you)，為了(le)滿足耐壓需(xu)要(yao)就必須是二個400VDC的(de)電容(rong)串起來作800VDC。容(rong)量選擇≥60uf/A

西門子6RA7091調速器顯示報警F006上門維修均壓電阻：防止由于儲能電容電壓的不均燒壞儲能電容；因為二個電解電容不可能做成*一致，這樣每個電容上所承受的電壓就可能不同，承受電壓高的發熱嚴重（電容里面有等效串聯電阻）或超過耐壓值而損壞。作用是防止開(kai)機(ji)(ji)上(shang)電(dian)(dian)(dian)(dian)瞬間(jian)(jian)電(dian)(dian)(dian)(dian)容(rong)(rong)對(dui)(dui)地短(duan)路(lu)，燒壞儲(chu)能電(dian)(dian)(dian)(dian)容(rong)(rong)開(kai)機(ji)(ji)前(qian)電(dian)(dian)(dian)(dian)容(rong)(rong)二端的(de)電(dian)(dian)(dian)(dian)壓為(wei) 0V；所以在(zai)上(shang)電(dian)(dian)(dian)(dian)（開(kai)機(ji)(ji)）的(de)瞬間(jian)(jian)電(dian)(dian)(dian)(dian)容(rong)(rong)對(dui)(dui)地為(wei)短(duan)路(lu)狀態。如果不加充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)阻在(zai)整(zheng)流(liu)橋與電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)之(zhi)間(jian)(jian)，則相當(dang)于380V電(dian)(dian)(dian)(dian)源直接(jie)對(dui)(dui)地短(duan)路(lu)，瞬間(jian)(jian)整(zheng)流(liu)橋通過(guo)無窮大(da)的(de)電(dian)(dian)(dian)(dian)流(liu)導(dao)致(zhi)整(zheng)流(liu)橋炸掉。一般而言變(bian)頻器的(de)功率越(yue)大(da)，充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)阻越(yue)小。充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)阻的(de)選(xuan)擇(ze)范圍一般為(wei)：10-300Ω。
