當市電輸入正常時，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。 </p><p style="text-indent:25px"><p>UPS中文為“不間斷電源”。是一種含儲能裝置，以整流器、逆變器為主要組成部分，為變電站內(nèi)監(jiān)控系統(tǒng)、自動化儀表、遠方通信系統(tǒng)等設(shè)備提供恒壓恒頻的不間斷電源。<p>UPS系統(tǒng)的主要作用有兩方面：<p>做為重要設(shè)備的交流供電電源，防止市電突然斷電而影響正常工作，給設(shè)備造成損害；<p>消除市電中的電涌、瞬間高/低電壓、電線噪聲和頻率偏移等“電源污染”，改善電源質(zhì)量，為計算機等提供高質(zhì)量的電源。<p>UPS的分類<p>UPS系統(tǒng)主要有有三種類型：后備式、互動式、在線式。<p>后備式：具備自動穩(wěn)壓、斷電保護等功能，轉(zhuǎn)換時間10ms左右，逆變輸出的交流電是方波，結(jié)構(gòu)簡單，價格便宜；<p>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；<p>在線式：結(jié)構(gòu)較復雜，性能完善，能夠持續(xù)不中斷輸出純凈正弦波交流電，能夠解決尖峰、浪涌、頻率漂移等全部的電源問題；價格高，通常應(yīng)用在關(guān)鍵計算機和網(wǎng)絡(luò)設(shè)備等對電力要求苛刻的環(huán)境中。UPS系統(tǒng)是數(shù)據(jù)中心供電連續(xù)性的重要保障，UPS系統(tǒng)的可靠性直接影響數(shù)據(jù)中心的可靠性；</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(shè)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(shè)備，所以容量很少有超過3KVA的。電池是UPS的重要組成部分，在UPS的諸多故障中，有很大比例是由于電池問題引起的。四川機房**ups不間斷電源維修</p><p
