從結(jié)構(gòu)上看，UPS設(shè)備可以分為后備式、在線互動(dòng)式、雙轉(zhuǎn)換在線式、Delta轉(zhuǎn)換在線式等類型，其中前兩種主要用于小容量負(fù)載（≤5kVA），Delta轉(zhuǎn)換在線式技術(shù)受**保護(hù)，因此，大型數(shù)據(jù)中心主要采用雙轉(zhuǎn)換在線式UPS設(shè)備。 </p> <p>

UPS的作用 </p> <p> UPS中文為“不間斷電源”。是一種含儲(chǔ)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(dòng)化儀表、遠(yuǎn)方通信系統(tǒng)等設(shè)備提供恒壓恒頻的不間斷電源。 </p> <p> UPS系統(tǒng)的主要作用有兩方面： </p> <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> <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(jì)算機(jī)等提供高質(zhì)量的電源。 </p> <p> UPS系統(tǒng)主要有有三種類型：后備式、互動(dòng)式、在線式。性能越好，保護(hù)能力也越強(qiáng)，總的來說，離線式UPS對(duì)負(fù)載的保護(hù)很差，在線互動(dòng)式略優(yōu)之。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

</p> <p> 從原理上來說，UPS是一種集數(shù)字和模擬電路,自動(dòng)控制逆變器與免維護(hù)貯能裝置于一體的電力電子設(shè)備; </p> <p> 從功能上來說，UPS可以在市電出現(xiàn)異常時(shí),有效地凈化市電;還可以在市電突然中斷時(shí)持續(xù)一定時(shí)間給電腦等設(shè)備供電,使你能有充裕的時(shí)間應(yīng)付; </p> <p> 從用途上來說，隨著信息化社會(huì)的來臨，UPS普遍地應(yīng)用于從信息采集、傳送、處理、儲(chǔ)存到應(yīng)用的各個(gè)環(huán)節(jié)，其重要性是隨著信息應(yīng)用重要性的日益提高而增加的。都是由UPS電源的逆變器對(duì)負(fù)載供電，這樣就避免了所有由市電電網(wǎng)電壓波動(dòng)及干擾而帶來的影響。銅仁ups不間斷電源維修</p><p

在線互動(dòng)式UPS電源也被稱為3端口式UPS電源，使用的是工頻變壓器。從能量傳遞的角度來考慮，其變壓器存在3個(gè)能量流動(dòng)的端口：端口1連接市電輸入；端口2通過雙向變換器與蓄電池相連；端口3輸出。 </p> <p> 市電供電時(shí)，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(shí)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(dá)到比較好的穩(wěn)壓效果；市電掉電時(shí)，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。銅仁ups不間斷電源維修</p><p
