所以就選擇了6500W的在線式主機(jī)。3.計(jì)算蓄電池的工作時(shí)間蓄電池的基本參數(shù)：電壓(2V、6V、12V等)、容量(65AH，宜春美克ups不間斷電源多少錢、100AH等)。在實(shí)踐過(guò)程中，我們總結(jié)出下面的公式，可以計(jì)算出蓄電池的工作時(shí)間：蓄電池組容量×電壓/主機(jī)額定功率×(功率因數(shù))=滿載時(shí)蓄電池工作時(shí)間。例如我們的UPS系統(tǒng)，主機(jī)額定工作功率6500W，3個(gè)電池柜共30塊鉛酸蓄電池，每塊電壓12V，容量100AH，宜春美克ups不間斷電源多少錢。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(shí)蓄電池工作時(shí)間為：300AH×120V/6500W×。這說(shuō)明該系統(tǒng)在斷電時(shí)蓄電池至少可以工作。以實(shí)際負(fù)載功率計(jì)算：300AH×120V/4500W=8小時(shí)我們的前端UPS系統(tǒng)在斷電時(shí)，**多堅(jiān)持8個(gè)小時(shí)，此結(jié)果經(jīng)過(guò)我們多次放電實(shí)驗(yàn)，證明是正確的。上述公式如果反推，根據(jù)當(dāng)?shù)貙?shí)際情況，確定蓄電池所需要的工作時(shí)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，宜春美克ups不間斷電源多少錢，線徑太細(xì)，電流太大，容易發(fā)熱而引起火災(zāi)；線徑太粗，則造成浪費(fèi)。根據(jù)金屬導(dǎo)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(jī)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(gòu)買UPS電源時(shí)。</p><div

目前UPS的發(fā)展方向是高頻機(jī)型UPS替代工頻機(jī)型UPS，因?yàn)槭紫雀哳l機(jī)型UPS相比工頻機(jī)型UPS來(lái)講，不僅取消了笨重的變壓器，在效率方面也是提高了近5%?？墒菄?guó)內(nèi)的現(xiàn)狀就是還有些戶對(duì)高頻機(jī)不太信任，這一方面也是因?yàn)樾麄鞯木壒?。造成了普遍用戶?duì)高頻機(jī)的不信任。雖然工頻機(jī)型UPS使用的歷史比較長(zhǎng)，但由于它固有的缺點(diǎn)想真正提高機(jī)房節(jié)能是不太可能實(shí)現(xiàn)的，如圖1所示。技術(shù)總是在發(fā)展的，新技術(shù)代替舊技術(shù)是歷史的發(fā)展規(guī)律。然而，新舊之間的替代與轉(zhuǎn)換一般并不是那么順利，人類社會(huì)是這樣，自然、科技領(lǐng)域也是如此?，F(xiàn)在的電子技術(shù)已進(jìn)入數(shù)字化時(shí)代，這是不可逆轉(zhuǎn)的技術(shù)發(fā)展規(guī)律，各行各業(yè)遲早都要集中到這一條路上來(lái)，但就某一個(gè)時(shí)期來(lái)說(shuō)發(fā)展是不平衡的，這中間有很多因素的影響，比如各自的技術(shù)發(fā)展水平不同，人員對(duì)新技術(shù)的認(rèn)識(shí)和接受能力不同等等。具體到UPS領(lǐng)域又何嘗不是如此。一、工頻機(jī)UPS和高頻UPS的一般概念靜止變換式工頻機(jī)結(jié)構(gòu)UPS技術(shù)出現(xiàn)在上個(gè)世紀(jì)70年代，毫無(wú)疑問(wèn)在當(dāng)時(shí)屬前列技術(shù)，幾十年間也為電子電器技術(shù)領(lǐng)域作出了不朽的貢獻(xiàn)，****。一般說(shuō)任何技術(shù)的先進(jìn)性是相對(duì)而言，任何先進(jìn)的產(chǎn)品也有其一定的適用期。隨著IT技術(shù)的出現(xiàn)與發(fā)展。</p><div

其發(fā)展大致經(jīng)歷了三個(gè)階段：①整組電壓監(jiān)測(cè)、②單電池電壓監(jiān)測(cè)、③單電池內(nèi)阻巡檢1）整組電壓監(jiān)測(cè)整組電池監(jiān)測(cè)功能一般設(shè)計(jì)在整流電源內(nèi)，測(cè)量電池組的電壓，電流和溫度，進(jìn)行充電和放電管理，尤其是根據(jù)環(huán)境溫度變化調(diào)整電池的浮充電壓，在電池放電時(shí)電池組電壓低至某下限時(shí)報(bào)警，現(xiàn)在的UPS仍然采用該方法。但是整組監(jiān)測(cè)存在較大的不足,如在蓄電池組放電時(shí),放電的截止電壓是N×(N為蓄電池?cái)?shù)量),但是由于蓄電池組中蓄電池的一致性無(wú)法嚴(yán)格保證，因此在放電中當(dāng)個(gè)別電池已經(jīng)達(dá)到放電截止電壓，但電池組并沒(méi)有達(dá)到N×，這樣就會(huì)出現(xiàn)個(gè)別電池過(guò)放電。2）單電池電壓監(jiān)測(cè)全電子式的監(jiān)測(cè)，對(duì)蓄電池的運(yùn)行情況可以作到較為***的監(jiān)測(cè)與管理，如單電池電壓、電池組電壓、充放電電流、蓄電池的環(huán)境溫度等。通過(guò)蓄電池運(yùn)行參數(shù)的監(jiān)測(cè)，可以保證蓄電池在正常條件下的運(yùn)行與工作。但當(dāng)蓄電池運(yùn)行條件無(wú)法保障的前提下，蓄電池運(yùn)行參數(shù)的監(jiān)測(cè)是無(wú)法反映其性能參數(shù)的。3）單電池內(nèi)阻監(jiān)測(cè)電池總內(nèi)阻是電荷轉(zhuǎn)移電阻與各部件歐姆電阻的總和，實(shí)驗(yàn)表明：歐姆阻抗是電池早期失效的比較大***。以下是**通常的影響內(nèi)阻變化的因素：腐蝕隨柵板和匯流排的腐蝕，金屬導(dǎo)電回路變化，使內(nèi)阻增大。</p><div
