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，張家界機房**ups不間斷電源廠家.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。功率因數一般在為0，張家界機房**ups不間斷電源廠家，張家界機房**ups不間斷電源廠家.6到0.8之間，若低于0.5則UPS設計不佳，在選購UPS時，應考慮功率因數問題。

style="text-indent:25px"><p>UPS的主要功能:<p>實現電網與用電器之間的隔離；<p>實現兩路電源的不間斷切換；<p>提供高質量電源；<p>電壓變換和頻率變換功能；<p>停電后提供后備時間。<p>UPS的基本原理<p>后備式UPS運行原理<p>有市電時，市電通過開關后直接供給負載，逆變器不工作；另外，市電通過充電器給電池充電。<p>停電后，啟動逆變器，把電池儲存的能量通過逆變器和開關供給負載。<p>功率等級0.25-2KVA左右<p>互動式UPS運行原理<p>在線互動UPS與后備式比，主要區(qū)別在于：逆變器與充電器合二為一；輸出通過變壓器的抽頭跳變，實現分段穩(wěn)壓。<p>功率等級0.7-20KVA左右<p>在線式UPS運行原理<p>不管電網電壓是否正常，負載所用的交流電壓都要經過逆變電路，即逆變電路始終處于工作狀態(tài)。<p>功率等級0.7-1500KVA左右</p><p style="text-indent:25px"><p>UPS電源是將蓄電池與主機相連接，通過主機逆變器等模塊電路將直流電轉換成市電的系統(tǒng)設備。主要用于給計算機、計算機網絡系統(tǒng)或其它電力電子設備如電磁閥、壓力變送器等提供穩(wěn)定、不間斷的電力供應。保證了電腦中正在操作的重要數據不被丟失。<p>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。它主要作用是為單臺計算機、計算機網絡系統(tǒng)或其它電力電子設備提供不間斷的電力供應。當市電輸入正常時，UPS不間斷電源將市電穩(wěn)壓后提供負載使用，此時的UPS電源就相當于是一臺交流市電穩(wěn)壓器，同時它還向機內電池進行充電;當市電中斷時，UPS就會立即將機內電池的電能，通過逆變轉換的方法向負載繼續(xù)供應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。UPS作為保護性的電源設備，它的性能參數具有重要意義，應是我們選購時的考慮重點。</p><div

LBS的作用是將兩組UPS同步，目的是為了使STS的切換時間為零。 </p> <p> 雙總線的作用是為了給用電設備提供冗余的電源。 </p> <p> EPS和在線式UPS的主要區(qū)別是什么？兩者的主要用途是什么？ </p> <p> 與UPS相同之處：EPS是***的后備式UPS，它的工作原理和后備式UPS一樣。 </p> <p> 不同之處：EPS由于帶的負載不同，比如照明和啟動水泵等，功率需要做的很大，在啟動水泵時可以將逆變器做成變頻器；而后備式UPS由于主要的對象是PC機之類的IT設備，所以容量很少有超過3KVA的。發(fā)展UPS技術的主要目的是提高UPS對輸出端負載的動態(tài)響應越來越快又好。資陽艾默生ups不間斷電源廠商</p><p style="text-indent:25px">還有UPS效率、功率因數、轉換時間等都是表征UPS性能的重要參數。張家界機房**ups不間斷電源廠家</p><p> 在線互動式UPS電源在變壓器抽頭切換的過程中，雙向變換器作為逆變器方式工作。蓄電池供電，因此能實現輸出電壓的不間斷，同樣在由市電供電到電池供電的切換過程中也能做到沒有轉換時間。在線互動式UPS電源的電路實現簡單，沒有單獨的充電器，帶來的是生產成本的降低和可靠性的提高。 </p> <p> 這類產品在市電供電工作時也不存在AC／DC、DC／AC的轉換，使整機效率有所提高。在線互動式UPS很好地結合了后備式UPS和在線式UPS的許多優(yōu)點，是一種很不錯的變換形式。但是由于它使用的是工頻變壓器，同樣有笨重、體積大的問題。張家界機房**ups不間斷電源廠家</p><p
