每次20～30分鐘。對于長時(shí)問不用的電解屯容器，通電時(shí)，先加約50%的額定電壓，只要加壓時(shí)間在半小時(shí)以上，它的漏電流就會降下去，也就可以正常使用了。此外，對使用年限較長(五年以上)的變頻器，也一定要對儲能電容器進(jìn)行容量檢測。運(yùn)行中頻繁跳欠電壓故障，多數(shù)為直流電路的電容器容量不足、有容量下降或失容現(xiàn)象。開關(guān)模式電源（SwitchModePowerSupply，簡稱SMPS），又稱交換式電源、開關(guān)變換器，是一種高頻化電能轉(zhuǎn)換裝置，是電源供應(yīng)器的一種。其功能是將一個(gè)位準(zhǔn)的電壓，透過不同形式的架構(gòu)轉(zhuǎn)換為用戶端所需求的電壓或電流。開關(guān)電源的輸入多半是交流電源（例如市電）或是直流電源，而輸出多半是需要直流電源的設(shè)備。
