UPS電源一直使其逆變器處于工作狀態(tài)，它首先通過電路將外部交流電轉(zhuǎn)變?yōu)?直流電，再通過高質(zhì)量的逆變器將直流電轉(zhuǎn)換為高質(zhì)量的正弦波交流電輸出給計算機。在線式UPS在供電狀況下的主要功能是穩(wěn)壓及防止電波干擾;在停電時則使用備用直流電源( 蓄電池組)給逆變器供電。由于逆變器一直在工作，因此不存在切換時間問題，適用于對電源有嚴格要求的場合。在線式UPS電源不同于后備式的一大優(yōu)點是供電持續(xù)長，一般為幾個小時，也有大到十幾個小時的，它的主要功能是可以讓您在停電的情況可像平常一樣工作，顯然，由于其功能的特殊，價格也明顯要貴一大截。這種在線式UPS比較適用于計算機、交通、銀行、證券、通信、醫(yī)療、工業(yè)控制等行業(yè)，因為這些領(lǐng)域的電腦一般不允許出現(xiàn)停電現(xiàn)象。武漢電力用UPS不間斷電源廠家推薦UPS不間斷電源保證用戶能夠有一個干凈的電源，保護用戶的設(shè)備。</p><div

Supply”的縮寫，它可以保障計算機系統(tǒng)在停電之后繼續(xù)工作一段時間以使用戶能夠緊急存盤，使您不致因停電而影響工作或丟失數(shù)據(jù)。它在計算機系統(tǒng)和網(wǎng)絡(luò)應(yīng)用中，主要起到兩個作用：一是應(yīng)急使用，防止突然斷電而影響正常工作，給計算機造成損害；二是消除市電上的電涌、瞬間高電壓、瞬間低電壓、電線噪聲和頻率偏移等“電源污染”，改善電源質(zhì)量，為計算機系統(tǒng)提供高質(zhì)量的電源。從基本應(yīng)用原理上講，UPS是一種含有儲能裝置，以逆變器為主要元件，穩(wěn)壓穩(wěn)頻輸出的電源保護設(shè)備。主要由整流器、蓄電池、逆變器和靜態(tài)開關(guān)等幾部分組成。整流器：整流器是一個整流裝置，簡單的說就是將交流（AC）轉(zhuǎn)化為直流（DC）的裝置。它有兩個主要功能：一，將交流電（AC）變成直流電(DC)，經(jīng)濾波后供給負載，或者供給逆變器；第二，給蓄電池提供充電電壓。因此，它同時又起到一個充電器的作用；</p><p style="text-indent:25px">一個好的UPS電源一般能供電多長時間?不能用延時長短來確定UPS電源的好壞。　　UPS電源由主機和電池兩部分構(gòu)成。延時（供電）時間長短取決于所配電池容量大小和負載輕重。標準配置的電池，只能用于市電中斷后緊急處理事務(wù)5分鐘左右。需要長延時，商家會根據(jù)所要延時的具體時間，比如2小時，4小時來計算確定。確定延長多少時間是指滿載時電池可以供電的時間。如，滿載時可以供電2小時，半載時則可以達到4小時。任達能源后備式UPS一般內(nèi)置4AH或7AH的電池，其備用時間是固定的；在線式與在線互動式UPS有內(nèi)置7AH電池的標準機型，也有外配大容量電池的長效機型，用戶可以根據(jù)需要實現(xiàn)的備用時間而確定配備多大容量的電池。 UPS電源后備延時時間計算方法：(電池容量X電池工作電壓)/設(shè)備功率=可延長時間(小時)UPS不間斷電源一般不要滿載或超載運行，否則會使UPS電源的故障率明顯增多。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">在線式UPS輸出正弦波的波形失真系數(shù)較小，一般小于3%。市電中斷時在線式UPS能真正實現(xiàn)對負載的不間斷供電。只要機內(nèi)蓄電池能向UPS逆變器提供能量，無論市電是否中斷，在線式UPS都是由逆變器向負載供電。因此，從市電供電到市電中斷的過程中，在線式UPS內(nèi)部并沒有產(chǎn)生任何轉(zhuǎn)換動作，其對負載供電的轉(zhuǎn)換時間為零。在線式UPS同后備式UPS相比，具有優(yōu)良的輸出電壓瞬變特性。一般在l00%負載加載或99%負載減載時，它的輸出電壓變化范圍為1%左右，這種變化的持續(xù)時間一般為1~3周波。在線式UPS一般采用20kHz以上的PWM技術(shù)，其噪聲較小，約為50dB。在線式UPS的控制電路中，采用輸入變壓器、輸出變壓器及光電耦合器件等將“強電”驅(qū)動部分與“弱電”控制線路部分從電的角度隔離開來，因而電路的可靠性得到了極大的提高。這種UPS的故障率一般都很低。UPS不間斷電源設(shè)備通常對電壓過大和電壓太低都提供有力的保護。武漢電力用UPS不間斷電源廠家推薦</p><p

style="text-indent:25px">電路組成及各環(huán)節(jié)功能：當前，絕大多數(shù)在線式UPS都采用雙變換電路結(jié)構(gòu)，雙變換在線式UPS結(jié)構(gòu)組成及功能： 1)變換器1:該變換器為AC/DC單向變換。當市電存在時，它完成對蓄電池的充電，并通過變換器2向負載供電。該變換器多為不可控整流或可控整流電路。 2)變換器2:該變換器為DC/AC單向逆變。當市電存在時，它由變換器l獲得直流電能后再轉(zhuǎn)換為交流后輸出至負載，并保證向負載提供高質(zhì)量的交流電源;當市電中斷時，由蓄電池通過變換器2向負載供電。 3)旁路開關(guān):平時處在斷開狀態(tài)，當變換電路發(fā)生故障、負載有沖擊性(例如啟動負載時)或發(fā)生過載故障時，變換器停止輸出，旁路開關(guān)接通，由電網(wǎng)直接向負載供電，旁路開關(guān)多為智能型的功率容量很強的無觸點開關(guān)。武漢電力用UPS不間斷電源廠家推薦</p></p><br /><p>文章來源地址:
