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），樂山機房ups不間斷電源公司。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，樂山機房ups不間斷電源公司，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，樂山機房ups不間斷電源公司。

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)。當市電輸入正常時，UPS不間斷電源將市電穩(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，UPS不間斷電源設(shè)備通常對電壓過大和電壓太低都提供保護。樂山機房ups不間斷電源公司UPS主機現(xiàn)場應(yīng)放置操作指南，指導(dǎo)現(xiàn)場操作。</p><div

</p> <p> 市電供電時，交流電經(jīng)端口1流入變壓器，在穩(wěn)壓電路的控制下選擇合適的變壓器抽頭接入，同時在端口2的雙向變換器的作用下借助蓄電池的能量轉(zhuǎn)換共同調(diào)節(jié)端口3上的輸出電壓，以此來達到比較好的穩(wěn)壓效果；市電掉電時，蓄電池通過雙向變換器經(jīng)端口2給變壓器供電，維持端口3上的交流輸出。

對于多數(shù)小型UPS，上班再開UPS，開機時要避免帶載啟動，下班時應(yīng)關(guān)閉UPS；對于網(wǎng)絡(luò)機房的UPS，由于多數(shù)網(wǎng)絡(luò)是24小時工作的，所以UPS也必須全天候運行。 </p> <p> UPS放電后應(yīng)及時充電，避免電池因過度自放電而損壞。互動式：具有濾波功能，抗市電干擾能力強，轉(zhuǎn)換時間小于4ms，逆變輸出為模擬正弦波，價格遠低于在線式；樂山機房ups不間斷電源公司</p><p style="text-indent:25px">因為UPS裝了防雷充其量只能使配電柜中省一級防雷，但是配電當中還是不能省略防雷裝置。樂山機房ups不間斷電源公司</p><p>離線式不間斷電源，也稱為后備式不間斷電源，如上圖所示。平常市電通過旁路直接向負載供電，機內(nèi)的逆變器處于停止工作狀態(tài)，這時的UPS電源實質(zhì)上相當于一臺性能較差的市電穩(wěn)壓器，它除了對市電電壓的幅度波動有所改善外，對電壓的頻率不穩(wěn)、波形畸變以及從電網(wǎng)侵入的干擾等不良影響基本上沒有任何改善。只有在停電時，才通過逆變器將電池能量轉(zhuǎn)換為交流向負載提供電力。<p>在市電正常供電時，它首先將市電交流電源經(jīng)整流變成直流電源，然后進行脈寬調(diào)制、濾波，再將直流電經(jīng)逆變器重新轉(zhuǎn)換成正弦波交流電源向負載供電。一旦市電中斷，立即改由蓄電池提供的直流電經(jīng)逆變器向負載提供正弦波交流電源。因此，對在線式UPS電源而言，在正常情況下，無論有無市電，它都是由UPS電源的逆變器對負載供電，這樣就避免了所有由市電電網(wǎng)電壓波動及干擾而帶來的影響。顯而易見，在線式UPS電源的供電質(zhì)量明顯優(yōu)于后備式UPS電源。因為它可以實現(xiàn)對負載的穩(wěn)頻、穩(wěn)壓供電，而且在由市電供電轉(zhuǎn)換到蓄電池供電時，其轉(zhuǎn)換時間為零。真正給用戶提供質(zhì)量的穩(wěn)壓、穩(wěn)頻的純凈正弦波電源，從而提供符合網(wǎng)絡(luò)系統(tǒng)需要的電源保護。<p><br/><p><br/><p><br/><p><br/>樂山機房ups不間斷電源公司<p
