對(duì)于UPS電源長(zhǎng)期處于市電低電壓供電或頻繁停電的用戶來(lái)說(shuō)，為防止電池因長(zhǎng)期充電不足而過(guò)早損壞，應(yīng)充分利用供電高峰(如深夜時(shí)間)對(duì)電池充電以保證電池在每次放電之后有足夠的充電時(shí)間。一般電池被深度放電后，再充電至額定容量的90%至少需要10～12h左右。注意充電器的選用。 </p> <p> UPS電源用的免維護(hù)密封電池不能用可控硅式的“快速充電器”進(jìn)行充電。這是因?yàn)檫@種充電器會(huì)造成蓄電池同時(shí)處于既“瞬時(shí)過(guò)流充電”又“瞬時(shí)過(guò)壓充電的惡劣充電狀態(tài)。這種狀態(tài)會(huì)使電池可供使用容量大力下降，嚴(yán)重時(shí)會(huì)使蓄電池報(bào)廢。在采用恒壓截止型充電回路的UPS電源時(shí)，注意不要將電池電壓過(guò)低保護(hù)工作點(diǎn)調(diào)得過(guò)低，否則，在它充電初期容易產(chǎn)生過(guò)流充電。當(dāng)然，比較好選用既具有恒流，又有恒壓的充電器對(duì)其進(jìn)行充電。 UPS 立即將電池的直流電能，通過(guò)逆變器切換轉(zhuǎn)換的方法向負(fù)載繼續(xù)供應(yīng)220V交流電。貴陽(yáng)機(jī)房**ups不間斷電源維修</p><p style="text-indent:25px">UPS 將市電穩(wěn)壓后供應(yīng)給負(fù)載使用，此時(shí)的UPS就是一臺(tái)交流式電穩(wěn)壓器；貴陽(yáng)機(jī)房**ups不間斷電源維修</p><p> 如何延長(zhǎng)不間斷電源（UPS）的供電時(shí)間 </p> <p> 延長(zhǎng)不間斷電源的供電時(shí)間有兩種方法： </p> <p> 增加電池容量。可以根據(jù)所需供電的時(shí)間長(zhǎng)短增加電池的數(shù)量，但是采用這種方法會(huì)造成電池充電時(shí)間的相對(duì)增加，同時(shí)也會(huì)增加相應(yīng)的維護(hù)設(shè)備的數(shù)量、增大產(chǎn)品體積，造成UPS整體成本提高； </p> <p> 選購(gòu)容量較大的UPS。采用這種方法不僅可以降低維修成本，如果需要擴(kuò)充負(fù)載設(shè)備，較大容量的不間斷電源仍可正常工作。 </p> <p> 不間斷電源（UPS）的容量如何計(jì)算 </p> <p> 目前市場(chǎng)上銷售的不間斷電源（UPS）多以VA作為容量單位。V是電壓，A是電流，V×A就等于功率，即不間斷電源的容量。例如，一臺(tái)425VA的不間斷電源，如果其輸出電壓為110V，則該UPS能夠提從的比較大電流為3.86A，超過(guò)此電流值就是超載（Overload）。另一種表示功率的方法是W，W表示實(shí)功，VA表示虛功。兩者之間的差別在于功率因數(shù)。功率因數(shù)一般在為0.6到0.8之間，若低于0.5則UPS設(shè)計(jì)不佳，在選購(gòu)UPS時(shí)，應(yīng)考慮功率因數(shù)問題。貴陽(yáng)機(jī)房**ups不間斷電源維修</p><p
