再加上輸出變壓器，就比高頻機UPS多了兩個環(huán)節(jié)，如圖1所示。由于此二者的影響，使得工頻機UPS的效率比高頻機UPS低5%。在同樣是100kW的容量時工頻機UPS每年要比高頻機UPS多消耗5萬度電！這在**號召節(jié)能減排的***，能源的節(jié)約具有深遠意義。圖1高輸入功率因數(shù)下的工頻機UPS和高頻機UPS結(jié)構(gòu)方框3、對外干擾小UPS的干擾一般有兩種，一種是聽得到的機械噪聲，一種是聽不到的電噪聲，這兩種噪聲工頻機UPS都有，形成了對設(shè)備和對人的傷害。電噪聲影響機器的穩(wěn)定度，機械噪聲影響人的身心健康，降低工作效率。而高頻機UPS由于工作在20kHz以上，20kHz是人的耳朵聽不到的頻率，使工作環(huán)境安靜下來。又由于一般的高頻機UPS的輸入功率因數(shù)高達，幾乎是線性，所以對外干擾幾乎為零。4、體積小、重量輕工頻機UPS由于有了輸出變壓器和適應50Hz的電感電容等低頻器件使得體積重量都很大。比如某品牌200kVA工頻機UPS重1380kg，而同是這一廠家的250kVA高頻機UPS重量只有830kg。5、全數(shù)字技術(shù)工頻機UPS開始是模擬技術(shù)，現(xiàn)在一般發(fā)展為數(shù)字與模擬相結(jié)合的技術(shù)。模擬技術(shù)的可靠性要比數(shù)字技術(shù)低。而高頻機UPS技術(shù)是一種全數(shù)字化技術(shù)，不言而喻，可靠性是很高的。九江捷益達ups不間斷電源上門安裝南昌穎頓科技有限公司多年精湛的工藝，完美設(shè)計。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="九江捷益達ups不間斷電源上門安裝,ups不間斷電源" src="https://tyunfile.71360.com/WaterMark/UploadFile/yingdun2020/637214349793144531/4992495.jpg"></div><p> UPS的作用就顯得更加明顯。[4]UPS的保護作用首先表現(xiàn)在對市電電源進行穩(wěn)壓，UPS的輸入電壓范圍比較寬，一般情況是從170V到250V，而輸出電源的質(zhì)量是相當高的，后備式的UPS輸出電壓在5%~8%，輸出頻率穩(wěn)定在1Hz；如圖1，在線式UPS輸出電壓穩(wěn)定在3%以內(nèi)，輸出頻率穩(wěn)定在。在市電正常時，UPS電源相當于交流市電穩(wěn)壓器；同時市電對蓄電池進行充電，此時也相當于充電器。在市電突然掉電的情況下，UPS自動切換到蓄電池供電，使計算機維持正常工作，保護軟硬件不受損害。[4]不間斷電源分類編輯UPS根據(jù)新標準IEC（國際電工**會）按其結(jié)構(gòu)和運行原理分為以下3類：[5]（1）被動后備式UPS電源指逆變器并聯(lián)連接在市電與負載之間*簡單地作為備用電源使用。此種UPS電源，在市電正常時，負載完全不間斷電源而且是直接地市電供電，逆變器不做任何電能變換，蓄電池由**的充電器供電；當市電不正常時，負載完全由逆變器提供電能。[5]被動后備式UPS具有結(jié)構(gòu)簡單、價格**廉等優(yōu)點，運用于某些非重要的負載使用，如家用計算機等。但市電斷電時，繼電器將逆變器切換至負載，切換時間較長，一般需幾個毫秒的間斷，所以稍微重要的計算機設(shè)備不應選用被動后備式UPS電源。[5]。</p><p> 所以就選擇了6500W的在線式主機。3.計算蓄電池的工作時間蓄電池的基本參數(shù)：電壓(2V、6V、12V等)、容量(65AH、100AH等)。在實踐過程中，我們總結(jié)出下面的公式，可以計算出蓄電池的工作時間：蓄電池組容量×電壓/主機額定功率×(功率因數(shù))=滿載時蓄電池工作時間。例如我們的UPS系統(tǒng)，主機額定工作功率6500W，3個電池柜共30塊鉛酸蓄電池，每塊電壓12V，容量100AH。所以電池組電壓=12V×10=120V電池組容量=100AH×3=300AH該系統(tǒng)滿載時蓄電池工作時間為：300AH×120V/6500W×。這說明該系統(tǒng)在斷電時蓄電池至少可以工作。以實際負載功率計算：300AH×120V/4500W=8小時我們的前端UPS系統(tǒng)在斷電時，**多堅持8個小時，此結(jié)果經(jīng)過我們多次放電實驗，證明是正確的。上述公式如果反推，根據(jù)當?shù)貙嶋H情況，確定蓄電池所需要的工作時間，就可以決定所需的蓄電池容量和電壓。4、配線選擇合理選擇配線是很重要的，線徑太細，電流太大，容易發(fā)熱而引起火災；線徑太粗，則造成浪費。根據(jù)金屬導線的電氣特性，一般多股銅芯線容量為6A/mm，鋁線容量為4A/mm，確定主機功率后，可以參考相關(guān)資料選擇配線和空氣開關(guān)。5.選擇品牌在購買UPS電源時。南昌穎頓科技有限公司信奉：只要耕耘，必有收獲。</p><div

1、市電有電時，UPS出現(xiàn)市電斷電告警 </p> <p> 可能原因： </p> <p> 市電輸入空開跳閘； </p> <p> 輸入交流線接觸不良； </p> <p> 市電輸入電壓過高、過低或頻率異常； </p> <p> UPS輸入空開或開關(guān)損壞或保險絲熔斷； </p> <p> UPS內(nèi)部市電檢測電路故障。 </p> <p> <br /> </p> <p> 處理方法 </p> <p> 檢查輸入空開。檢查輸入線路； </p> <p> 如市電異?？刹惶幚砘騿影l(fā)電機供電； </p> <p> 更換損壞的空開、開關(guān)或保險絲； </p> <p> 檢查UPS市電檢測回路。 </p> <p> <br /> </p> <p> 2、市電正常時，UPS輸出正常；市電斷電后，負載也跟著斷電 </p> <p> 可能原因 </p> <p> 由于市電經(jīng)常低壓，電池處于欠壓狀態(tài)； </p> <p> UPS充電器損壞，電池無法充電； </p> <p> 電池老化、損壞； </p> <p> 負載過載，UPS旁路輸出； </p> <p> 負載未接到UPS輸出； </p> <p> 長延時機型的電池組未連接或接觸不良； </p> <p> UPS逆變器未啟動（UPS面板控制開關(guān)未打開），負載由市電旁路供電； </p> <p> 逆變器損壞，UPS旁路輸出。 </p> <p> <br /> </p> <p> 處理方法 </p> <p> 在市電電壓正常時對電池充足電；啟動發(fā)電機對電池充電；在UPS輸入端加穩(wěn)壓器； </p> <p> <br /> </p> <p> 檢查充電器。更換電池； </p> <p> 減少負載。將負載接到UPS的輸出； </p> <p> 檢查電池組是否接對、接好； </p> <p> 啟動逆變器對負載供電（打開面板控制開關(guān)）； </p> <p> 檢查逆變器。 </p> <p> <br /> </p> <p> <br /> </p> 南昌穎頓科技有限公司秉承共贏的社會平臺。江西伊頓ups不間斷電源售后服務(wù)</p><p
