UPS（UninterruptiblePowerSystem），即不間斷電源，是一種含有儲(chǔ)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(tái)計(jì)算機(jī)、計(jì)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(shí)，UPS將市電穩(wěn)壓后供應(yīng)給負(fù)載使用，此時(shí)的UPS就是一臺(tái)交流市電穩(wěn)壓器，同時(shí)它還向機(jī)內(nèi)電池充電；當(dāng)市電中斷(故障停電)時(shí),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。 </p><p style="text-indent:25px"><p>UPS同時(shí)具備穩(wěn)壓、濾波等功能，有些UPS可以在故障或過載時(shí)改由市電旁路供電。<p>后備式的電壓輸出有較大的波動(dòng)，在170V-260V之間，采用高速繼電器實(shí)現(xiàn)市電和蓄電池之間的轉(zhuǎn)換，轉(zhuǎn)換時(shí)間小于10毫秒。在線式始終使用逆變電路工作，其電壓的穩(wěn)定性高，基本上在220V±5%范圍內(nèi)，對(duì)蓄電池基本不存在轉(zhuǎn)換時(shí)間；與市電旁路轉(zhuǎn)換采用靜態(tài)開關(guān)，轉(zhuǎn)換時(shí)間可以達(dá)到微秒級(jí)。<p>UPS輸出精度高、轉(zhuǎn)換時(shí)間快，同時(shí)造價(jià)較高（約為EPS的兩倍），平時(shí)能耗大（在線式），主機(jī)壽命較短（8-10年）。UPS的三大基本功能：穩(wěn)壓，濾波，不可間斷。</p><div

我們很常用的是后備式UPS,如四通HO系列與SD系列，它具備了自動(dòng)穩(wěn)壓、斷電保護(hù)等UPS很基礎(chǔ)也很重要的功能，雖然一般有10ms左右的轉(zhuǎn)換時(shí)間，逆變輸出的交流電是方波而非正弦波,但由于結(jié)構(gòu)簡(jiǎn)單而具有價(jià)格便宜,可靠性高等優(yōu)點(diǎn),因此廣泛應(yīng)用于微機(jī)、外設(shè)、POS機(jī)等領(lǐng)域; </p> <p> 在線式UPS結(jié)構(gòu)較復(fù)雜,但性能完善，能解決所有電源問題，如四通PS系列，其明顯特點(diǎn)是能夠持續(xù)零中斷地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;由于需要較大的投資,通常應(yīng)用在關(guān)鍵設(shè)備與網(wǎng)絡(luò)中心等對(duì)電力要求苛刻的環(huán)境中; UPS 設(shè)備通常對(duì)電壓過高或電壓過低都能提供保護(hù)。眉山科華ups不間斷電源維修</p><p style="text-indent:25px">UPS效率、功率因數(shù)、轉(zhuǎn)換時(shí)間等都是表征UPS性能的重要參數(shù)，決定了對(duì)負(fù)載的保護(hù)能力和對(duì)市電的利用率。眉山科華ups不間斷電源維修</p><p> 停電保護(hù)作用 </p> <p> 市電電網(wǎng)瞬間停電時(shí)立即由UPS電源系統(tǒng)將UPS蓄電池直流電源轉(zhuǎn)換成交流電繼續(xù)為負(fù)載供電，避免因停電而帶來的不便和損失。 </p> <p> 穩(wěn)壓作用 </p> <p> 市電電壓容易受電力輸送線路的距離和品質(zhì)影響，離變電所較近的用戶電壓較高，離變電所較遠(yuǎn)的用戶電壓則會(huì)偏低較低。電壓過高或過低都會(huì)影響用戶儀器設(shè)備的使用質(zhì)量和使用壽命，較嚴(yán)重時(shí)則會(huì)損壞設(shè)備，給用戶造成重大損失。UPS電源系統(tǒng)的使用則可以為用戶設(shè)備提供穩(wěn)定的電壓電源，保障設(shè)備的正常運(yùn)行和延長(zhǎng)使用壽命。 </p> <p> 突波保護(hù)作用 </p> <p> 通常UPS電源系統(tǒng)會(huì)有前列放電設(shè)計(jì)吸收突波，避免因突波問題影響設(shè)備的使用效率和壽命，為設(shè)備提供保護(hù)。眉山科華ups不間斷電源維修</p><p
