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> 傳統(tǒng)的雙轉(zhuǎn)換在線式UPS設(shè)備采用可控硅整流，主要的問題是諧波電流畸變率（THDi）高(10-30%)，轉(zhuǎn)換效率低(85-92%)。 </p> <p> 隨著電力電子器件的發(fā)展，呈現(xiàn)出IGBT取代可控硅整流的趨勢，IGBT整流的優(yōu)勢是取消變壓器，因而降低了成本，同時(shí)有比較好的輸入特性，在較寬的負(fù)載范圍內(nèi)，可以將THDi控制在5-10%之間，比較大的好處是效率的提升，通常在87-95%之間。目前，IGBT整流型UPS的可靠性比可控硅整流型略低。瀘州艾默生ups不間斷電源廠商UPS能在電力異常時(shí)有足夠的時(shí)間實(shí)施應(yīng)急措施。</p><div

style="text-indent:25px"><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>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(jì)算機(jī)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(dòng)式、在線式。<p>后備式：具備自動(dòng)穩(wěn)壓、斷電保護(hù)等功能，轉(zhuǎn)換時(shí)間10ms左右，逆變輸出的交流電是方波，結(jié)構(gòu)簡單，價(jià)格便宜；<p>互動(dòng)式：具有濾波功能，抗市電干擾能力強(qiáng)，轉(zhuǎn)換時(shí)間小于4ms，逆變輸出為模擬正弦波，價(jià)格遠(yuǎn)低于在線式；<p>在線式：結(jié)構(gòu)較復(fù)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(jià)格高，通常應(yīng)用在關(guān)鍵計(jì)算機(jī)和網(wǎng)絡(luò)設(shè)備等對電力要求苛刻的環(huán)境中。</p><p> UPS注意事項(xiàng) </p> <p> UPS的使用環(huán)境應(yīng)注意通風(fēng)良好，利于散熱，并保持環(huán)境的清潔。 </p> <p> 切勿帶感性負(fù)載，如點(diǎn)鈔機(jī)、日光燈、空調(diào)等，以免造成損壞。 </p> <p> UPS的輸出負(fù)載控制在60%左右為比較好，可靠性比較高。 </p> <p> UPS帶載過輕（如1000VA的UPS帶100VA負(fù)載）有可能造成電池的深度放電，會(huì)降低電池的使用壽命，應(yīng)盡量避免。 </p> <p> 適當(dāng)?shù)姆烹姡兄陔姵?，如長期不停市電，每隔三個(gè)月應(yīng)人為斷掉市電用UPS帶負(fù)載放電一次，這樣可以延長電池的使用壽命。 </p> <p> 對于多數(shù)小型UPS，上班再開UPS，開機(jī)時(shí)要避免帶載啟動(dòng)，下班時(shí)應(yīng)關(guān)閉UPS；對于網(wǎng)絡(luò)機(jī)房的UPS，由于多數(shù)網(wǎng)絡(luò)是24小時(shí)工作的，所以UPS也必須全天候運(yùn)行。 </p> <p> UPS放電后應(yīng)及時(shí)充電，避免電池因過度自放電而損壞。性能越好，保護(hù)能力也越強(qiáng)，總的來說，離線式UPS對負(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; max-height:

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。 UPS輸入輸出柜是針對UPS電源特性為UPS電源量身打造的配套產(chǎn)品；瀘州艾默生ups不間斷電源廠商</p><p
