style="text-indent:25px"><p>UPS（UNINTERRUPTIBLEPOWERSYSTEM）電源是不間斷電源的簡稱，其主要作用是通過蓄電池與主機(jī)相連的方式來為計算機(jī)或一些電子設(shè)備提供穩(wěn)定的，并且不間斷的電源供應(yīng)。主要是用來給重要的負(fù)載提供電力保護(hù)，包括消除電網(wǎng)中的各種電力擾動，如停電、電壓波動、頻率波動、諧波、電壓畸變、電噪聲、尖沖等。它是國際和國內(nèi)公認(rèn)的一種保護(hù)重要負(fù)載的產(chǎn)品，有嚴(yán)格的國際和國家標(biāo)準(zhǔn)。<p>UPS的工作原理是利用電池的化學(xué)能作為后備能，當(dāng)交流電出現(xiàn)故障中斷時，UPS可不間斷的為設(shè)備提供電能，一般由整流器、逆變器、靜態(tài)開關(guān)、蓄電池等組成。湖南科士達(dá)ups電源價格UPS電源**濾波器解決UPS電源諧波問題。濾除UPS電源產(chǎn)生的諧波,諧波電流畸變率降到5%~10%。</p><div

新購置UPS電源后，要將UPS電源插入220V市電電網(wǎng)中，充電至少12小時以上，以確保電池充電充分。否則，蓄電池的實際可供使用的容量將大力低于蓄電池的標(biāo)稱容量。若UPS電源長期不用。應(yīng)每隔2～3個月開機(jī)24小時，讓其充電充分，并讓UPS電源處于逆變器工作狀態(tài)下2～3分鐘，以保證電池的正常壽命。UPS電源一旦接通市電，即開始對電池組充電，持續(xù)按開機(jī)鍵1秒以上進(jìn)行開機(jī)，即開啟逆變器。 </p> <p> 個良好的安裝位置非常重要，放置UPS的地方必須具備良好的通風(fēng)效果，要遠(yuǎn)離水、可燃性氣體和腐蝕劑，環(huán)境溫度保持在0～40℃之間，若是在低溫下拆裝使用，可能會有水滴凝結(jié)現(xiàn)象。環(huán)境溫度一旦超過25度，每升高10度，電池的壽命就要縮短一半。目前UPS電源所用的蓄電池一般都是免維護(hù)的密封鉛酸電池，設(shè)計壽命普遍是5年。 </p><p> 為什么要用UPS </p> <p> 有一個常見的錯誤概念，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，其實不然。市電系統(tǒng)作為公共電網(wǎng)，上面連接了成千上萬各種各樣的負(fù)載，其中一些較大的感性、容性、開關(guān)電源等負(fù)載不僅從電網(wǎng)中獲得電能，還會反過來對電網(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，都會危害電力的正常供應(yīng)，從而影響負(fù)載的正常工作。 UPS電源輸出負(fù)載控制在60%左右為比較好，可靠性比較好。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="張家界醫(yī)用ups電源柜,ups電源" src="https://tyunfile.71360.com/WaterMark/UploadFile/cdjwjd/637300013056767578/481613.png"></div><p> 不間斷電源（UPS）供電時間多長才合適 </p> <p> UPS能在電力異常時有足夠的時間實施應(yīng)急措施。一般而言5-10分鐘的后備時間就足夠了。如果需要較長的后備時間，可以購買具有長延時功能的UPS。 </p> <p> 間斷電源（UPS）的容量如何計算 </p> <p> 目前市場上銷售的不間斷電源（UPS）多以VA作為容量單位。V是電壓，A是電流，V×A就等于功率，即不間斷電源的容量。例如，一臺425VA的不間斷電源，如果其輸出電壓為110V，則該UPS能夠提從的比較大電流為3.86A，超過此電流值就是超載（Overload）。另一種表示功率的方法是W，W表示實功，VA表示虛功。兩者之間的差別在于功率因數(shù)。功率因數(shù)一般在為0.6到0.8之間，若低于0.5則UPS設(shè)計不佳，在選購UPS時，應(yīng)考慮功率因數(shù)問題。 UPS電源一旦接通市電，即開始對電池組充電，持續(xù)按開機(jī)鍵1秒以上進(jìn)行開機(jī)，即開啟逆變器。湖南科士達(dá)ups電源價格</p><p
