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(jī)、計算機(jī)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(dāng)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(fù)載使用，瀘州艾默生ups不間斷電源公司，瀘州艾默生ups不間斷電源公司，瀘州艾默生ups不間斷電源公司，此時的UPS就是一臺交流市電穩(wěn)壓器，同時它還向機(jī)內(nèi)電池充電；當(dāng)市電中斷（故障停電）時，UPS立即將機(jī)內(nèi)電池的電能，通過逆變轉(zhuǎn)換的方法向負(fù)載繼續(xù)供應(yīng)220V交流電，使負(fù)載維持正常工作并保護(hù)負(fù)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(hù)。 UPS同時具備穩(wěn)壓、濾波等功能，有些UPS可以在故障或過載時改由市電旁路供電。瀘州艾默生ups不間斷電源公司</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="瀘州艾默生ups不間斷電源公司,ups不間斷電源"

使用UPS電源后，不必再加交流穩(wěn)壓器。若一定要加，應(yīng)加在UPS電源的前級，即市電先經(jīng)交流穩(wěn)壓器，再經(jīng)UPS電源，然后到負(fù)載。 </p> <p> 避免過載使用UPS電源 </p> <p> 在使用UPS電源的時候還要計算負(fù)載的大小，要避免負(fù)載的過大或者過小，過大的負(fù)載會使UPS電源長期工作在超負(fù)荷狀態(tài)從而縮短UPS電源的使用壽命;如果負(fù)載過小，UPS電源的工作電路長期工作在不正常狀態(tài)，這對于UPS電源也是有一定危害的。合理的負(fù)載應(yīng)該控制在50%到80%之間。實踐證明，UPS電源輸出負(fù)載控制在60%左右為比較好，可靠性比較好。在UPS電源出現(xiàn)過載或逆變器故障時會轉(zhuǎn)到旁路模式運行，此時UPS電源不具備后備功能，負(fù)載所用的電源是通過電力系統(tǒng)直接供應(yīng)的。瀘州艾默生ups不間斷電源公司發(fā)展UPS技術(shù)的主要目的是提高UPS對輸出端負(fù)載的動態(tài)響應(yīng)越來越快又好。</p><div

當(dāng)市電電壓時高時低，UP電源內(nèi)的穩(wěn)壓器(AVR)使市電電壓保持在可使用的安全范圍，確保設(shè)備可以正常運行。當(dāng)高低電壓超過可使用的范時，UPS電源系統(tǒng)則將啟動蓄電池供電，保障設(shè)備的持續(xù)運行。 </p> <p> 諧波失真保護(hù)作用 </p> <p> 電力經(jīng)由輸配電線路傳送至使用端時，電壓波形失真，基波電流發(fā)生變化產(chǎn)生諧波。諧波會影響設(shè)備的使用，通過UPS電源則能為設(shè)備提供穩(wěn)定***的電源，有效提高設(shè)備的運行效率和壽命。 </p> <p> <span style="display:none;"></span>穩(wěn)定頻率作用 </p> <p> 頻率就是市電每一秒變動的周期，50Hz就是每秒50周次。市電發(fā)電機(jī)運轉(zhuǎn)時受到用戶端用電量的突然變化而造成轉(zhuǎn)速的變動將使轉(zhuǎn)換出來的電力頻率不定，通過UPS電源轉(zhuǎn)換的電力可提供穩(wěn)定的頻率，確保儀器設(shè)備的正常工作。<span style="display:none;"></span>

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，同時，在絕大多數(shù)數(shù)據(jù)中心，UPS系統(tǒng)的損耗可占IT設(shè)備能耗的10%以上。因此，提高UPS系統(tǒng)的可靠性，同時降低其損耗，就成為數(shù)據(jù)中心UPS系統(tǒng)架構(gòu)演變的主旋律。瀘州艾默生ups不間斷電源公司</p><p
