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)，離線式UPS對(duì)負(fù)載的保護(hù)很差，在線互動(dòng)式略優(yōu)之，在線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,而選取不同類型的UPS。 </p><p> UPS電源不宜側(cè)放，應(yīng)保持進(jìn)風(fēng)孔與出風(fēng)孔通暢；負(fù)載與UPS電源連接時(shí)，須先關(guān)閉負(fù)載、再接線，然后逐個(gè)打開(kāi)負(fù)載，嚴(yán)禁將電動(dòng)、復(fù)印機(jī)等感性負(fù)載接入U(xiǎn)PS電源，以免造成傷害。將UPS電源接到**的帶有過(guò)電流保護(hù)裝置的插座上時(shí)，所用電源插座應(yīng)接保護(hù)地端；無(wú)論輸入電源線是否插入市電插座，UPS電源輸出都可能帶電。要使UPS電源無(wú)輸出，須先關(guān)掉開(kāi)關(guān)，再取消市電供應(yīng)。 </p> <p> 正確的開(kāi)機(jī)和關(guān)機(jī)順序應(yīng)該是先打開(kāi)UPS電源給它供電，然后再打開(kāi)各個(gè)負(fù)載，這樣可以避免啟動(dòng)時(shí)瞬間的電流沖擊給UPS造成的損害，在關(guān)機(jī)時(shí)的順序正好相反應(yīng)該先關(guān)閉各個(gè)負(fù)載末了關(guān)閉UPS。在市電中斷由UPS供電時(shí)，應(yīng)該盡快保存好自己的數(shù)據(jù)和資料然后關(guān)閉電腦，否則使用UPS電源進(jìn)行工作可能會(huì)使UPS過(guò)量放電，從而縮短UPS的使用壽命。

為了提高離線式UPS的利用率并改善其所在場(chǎng)合的電網(wǎng)電能質(zhì)量,研究了具有有源濾波功能的UPS電源。其本質(zhì)是對(duì)離線式UPS的一種改進(jìn),在基本不增加硬件成本的情況下,同時(shí)實(shí)現(xiàn)不間斷供電和有源濾波功能。系統(tǒng)可根據(jù)電網(wǎng)狀況,分別工作于APF模式和UPS模式。 </p> <p> UPS電源**濾波器解決UPS電源諧波問(wèn)題。濾除UPS電源產(chǎn)生的諧波,諧波電流畸變率降到5%~10%。UPS電源**濾波器提高系統(tǒng)可靠性,有效降低重負(fù)荷時(shí)負(fù)荷率,減小視在電流,控制諧波畸變,降低暫態(tài)過(guò)電壓,減小電壓電流變化率,保證用電可靠性。 </p> <p> UPS電源**濾波器可以提高UPS節(jié)能現(xiàn)象,不僅提高功率因數(shù),減少視在電流,又可以明顯降低高次諧波畸變,減少高次諧波損耗。 UPS同時(shí)具備穩(wěn)壓、濾波等功能，有些UPS可以在故障或過(guò)載時(shí)改由市電旁路供電。眉山山特ups電源廠商</p><p
