電解電容在(zai)變(bian)頻器中(zhong)主要的(de)(de)作(zuo)用(yong)就是濾波(bo)(bo)(bo)，濾波(bo)(bo)(bo)電(dian)(dian)(dian)(dian)(dian)容是并聯在(zai)整流電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)輸出端，用(yong)以降(jiang)低交(jiao)流脈動(dong)波(bo)(bo)(bo)紋系數(shu)、平滑直流輸出的(de)(de)一種儲(chu)能(neng)器件(jian)。在(zai)使用(yong)將(jiang)交(jiao)流轉換(huan)為直流供(gong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)中(zhong)，濾波(bo)(bo)(bo)電(dian)(dian)(dian)(dian)(dian)容不僅(jin)使電(dian)(dian)(dian)(dian)(dian)源直流輸出平穩，降(jiang)低了交(jiao)變(bian)脈動(dong)波(bo)(bo)(bo)紋對電(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)的(de)(de)影響，同時還可吸收電(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)工作(zuo)過程中(zhong)產生(sheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流波(bo)(bo)(bo)動(dong)和經由交(jiao)流電(dian)(dian)(dian)(dian)(dian)源串入(ru)的(de)(de)干擾，使得(de)電(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)的(de)(de)工作(zuo)性能(neng)更(geng)加穩定。

  西門子驅動器6RA80開機面板無顯示上門維修電解電容的(de)(de)基(ji)本失(shi)效情況是，長(chang)時(shi)間的(de)(de)使(shi)用，電解電容(rong)內部發熱，導致電解液慢慢干枯，從而失(shi)效，所以我嫩在選擇(ze)的(de)(de)時(shi)候，不僅要對電解電容(rong)的(de)(de)容(rong)量(liang)、電壓、漏電流、損耗(hao)角正(zheng)切(qie)進行檢測，同時(shi)也要關(guan)注電解電容(rong)的(de)(de)芯溫，溫升越低，損耗(hao)越慢，使(shi)用壽(shou)命就(jiu)越長(chang)。
