class="title">詳細(xì)說(shuō)明</p><div id="px8rtlx" class="box"><p><p> 不間斷電源（UPS）種類(lèi) </p> <p> UPS大致可分成三種：離線(xiàn)式（OffLine），在線(xiàn)式（Online）和在線(xiàn)交互式（Lineinteractive）。 </p> <p> 什么是離線(xiàn)式不間斷電源（OffLineUPS） </p> <p> 離線(xiàn)式不間斷電源如上圖所示，南充科華ups電源。平常市電通過(guò)旁路直接向負(fù)載供電。只有在停電時(shí)，才通過(guò)逆變器將電池能量轉(zhuǎn)換為交流向負(fù)載提供電力。離線(xiàn)式不間斷電源的特點(diǎn)： </p> <p> 當(dāng)市電正常時(shí)，離線(xiàn)式UPS對(duì)市電沒(méi)有任何處理而直接輸出至負(fù)載，因此對(duì)市電噪音以及浪涌的控制能力較差； </p> <p> 存在轉(zhuǎn)換時(shí)間； </p> <p> 保護(hù)性能很差； </p> <p> 結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕、控制容易，南充科華ups電源、成本低。在數(shù)據(jù)中心建設(shè)中，隨需擴(kuò)容、易維護(hù)，南充科華ups電源、高效率、高可用性以及占地小成為模塊化UPS比較大的優(yōu)勢(shì)。南充科華ups電源</p><div style="width:100%;text-align: center;"><img

有一個(gè)常見(jiàn)的錯(cuò)誤概念，認(rèn)為我們使用的市電，除了偶爾發(fā)生的斷電故障，是連續(xù)而且恒定的，其實(shí)不然。市電系統(tǒng)作為公共電網(wǎng)，上面連接了成千上萬(wàn)各種各樣的負(fù)載，其中一些較大的感性、容性、開(kāi)關(guān)電源等負(fù)載不*從電網(wǎng)中獲得電能，還會(huì)反過(guò)來(lái)對(duì)電網(wǎng)本身造成影響，惡化電網(wǎng)或局部電網(wǎng)的供電品質(zhì)，造成市電電壓波形畸變或頻率漂移。另外意外的自然和人為故障，如地震、雷擊、輸變電系統(tǒng)斷路或短路，都會(huì)危害電力的正常供應(yīng)，從而影響負(fù)載的正常工作。南充科華ups電源UPS電源具有直流開(kāi)機(jī)功能，不需要市電就可以直接啟動(dòng)UPS，方便使用。</p><div

UPS單機(jī)系統(tǒng)沒(méi)有容量的冗余，不能保護(hù)內(nèi)部模塊本身的故障。也不能保護(hù)設(shè)備的故障。因此，UPS內(nèi)部模塊、系統(tǒng)和配電均不能同時(shí)維護(hù)；內(nèi)部模塊和配電均無(wú)故障容限。所以，單機(jī)系統(tǒng)*適用于允許UPS停機(jī)2～4小時(shí)進(jìn)行維護(hù)，在此期間可以由帶有各種干擾的市電電源直接供電的負(fù)載。對(duì)于要求更高的可用度的應(yīng)用場(chǎng)合，雙變換UPS單機(jī)系統(tǒng)就不適用了。

UPS作為保護(hù)性的電源設(shè)備，它的性能參數(shù)具有重要意義，應(yīng)是我們選購(gòu)時(shí)的考慮重點(diǎn)。市電電壓輸入范圍寬，則表明對(duì)市電的利用能力強(qiáng)（減少電池放電）。輸出電壓、頻率范圍小，則表明對(duì)市電調(diào)整能力強(qiáng)，輸出穩(wěn)定。波形畸變率用以衡量輸出電壓波形的穩(wěn)定性,而電壓穩(wěn)定度則說(shuō)明當(dāng)UPS突然由零負(fù)載加到滿(mǎn)負(fù)載時(shí)，輸出電壓的穩(wěn)定性。 </p> <p> 還有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。性能越好，保護(hù)能力也越強(qiáng)，總的來(lái)說(shuō)，離線(xiàn)式UPS對(duì)負(fù)載的保護(hù)很差，在線(xiàn)互動(dòng)式略?xún)?yōu)之，在線(xiàn)式則幾乎可以解決所有的常見(jiàn)電力問(wèn)題。當(dāng)然成本也隨著性能的增強(qiáng)而上升。因此用戶(hù)在選購(gòu)UPS時(shí)，應(yīng)根據(jù)負(fù)載對(duì)電力的要求程度及負(fù)載的重要性不同,而選取不同類(lèi)型的UPS。 UPS電源不具備后備功能，負(fù)載所用的電源是通過(guò)電力系統(tǒng)直接供應(yīng)的。廣元科華ups電源維修</p><p style="text-indent:25px">UPS電源可以提供及時(shí)的供電，保證正常的工作運(yùn)行和正常的工作效率。南充科華ups電源</p><p
