增加電池容量。可以根據(jù)所需供電的時間長短增加電池的數(shù)量，但是采用這種方法會造成電池充電時間的相對增加，同時也會增加相應(yīng)的維護設(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，如果需要擴充負載設(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）的容量如何計算 </p> <p> 目前市場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)計不佳，在選購UPS時，應(yīng)考慮功率因數(shù)問題。達州機房***ups不間斷電源公司UPS，即不間斷電源，是一種含有儲能裝置，以逆變器為主要組成部分的恒壓恒頻的不間斷電源。</p><div

style="text-indent:25px">UPS（UninterruptiblePowerSystem），即不間斷電源，是一種含有儲能裝置，以逆變器為主要組成部分的恒壓恒頻的不間斷電源。主要用于給單臺計算機、計算機網(wǎng)絡(luò)系統(tǒng)或其它電力電子設(shè)備提供不間斷的電力供應(yīng)。當(dāng)市電輸入正常時，UPS將市電穩(wěn)壓后供應(yīng)給負載使用，此時的UPS就是一臺交流市電穩(wěn)壓器，同時它還向機內(nèi)電池充電；當(dāng)市電中斷(故障停電)時,UPS立即將機內(nèi)電池的電能,通過逆變轉(zhuǎn)換的方法向負載繼續(xù)供應(yīng)220V交流電，使負載維持正常工作并保護負載軟、硬件不受損壞。</p><p> UPS，就是不間斷電源。通常是弱電機房工程子系統(tǒng)之一，是將蓄電池與主機設(shè)備相連接，主要用于給設(shè)備提供穩(wěn)定、不間斷的電力供應(yīng) </p> <p> 當(dāng)市電輸入正常時，UPS將市電穩(wěn)壓后供應(yīng)給負載使用，此時的UPS就是一臺交流式電穩(wěn)壓器，同時它還向機內(nèi)電池充電；當(dāng)市電中斷（故障停電）時，UPS立即將電池的直流電能，通過逆變器切換轉(zhuǎn)換的方法向負載繼續(xù)供應(yīng)220V交流電，使負載維持正常工作并保護負載軟、硬件不受損壞。 </p> <p> UPS 設(shè)備通常對電壓過高或電壓過低都能提供保護。輸出電壓、頻率范圍小，則表明對市電調(diào)整能力強，輸出穩(wěn)定。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="云南山特ups不間斷電源廠家,ups不間斷電源"

經(jīng)常檢查設(shè)備的工作和故障指示是否正常。定期查看UPS內(nèi)部的元器件的外觀，發(fā)現(xiàn)異常及時處理。 </p> <p> 定期檢查UPS各主要模塊和風(fēng)扇電機的運行溫度有無異常。 </p> <p> 保持機器清潔，定期清潔散熱風(fēng)口、風(fēng)扇及濾網(wǎng)。 </p> <p> 定期進行UPS電池組帶載測試。 </p> <p> 各地應(yīng)根據(jù)當(dāng)?shù)厥须婎l率的變化情況，選擇合適的追蹤速率。 </p> <p> 當(dāng)輸入頻率波動頻繁且速率較高，超出UPS追蹤范圍時，嚴(yán)禁進行逆變/旁路切換操作。 </p> <p> 在油機供電時，尤其應(yīng)注意避免該情況的發(fā)生。UPS應(yīng)使用開放式電池架，以利于蓄電池的運行及維護。 UPS
