id="77vrtar" class="box"><p><p> 為了提高離線式UPS的利用率并改善其所在場合的電網(wǎng)電能質量,研究了具有有源濾波功能的UPS電源。其本質是對離線式UPS的一種改進,在基本不增加硬件成本的情況下,同時實現(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電源諧波問題。濾除UPS電源產生的諧波,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，張家界愛克賽ups電源廠商,有效降低重負荷時負荷率,減小視在電流,控制諧波畸變,降低暫態(tài)過電壓,減小電壓電流變化率，張家界愛克賽ups電源廠商,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，張家界愛克賽ups電源廠商,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。一般情況下建議不關閉UPS電源，以保持電池充電。張家界愛克賽ups電源廠商</p><div style="width:100%;text-align: center;"><img style="max-width:

用戶在挑選UPS電源時，應根據(jù)自己的要求來確定挑選標準，選擇很適合使用的UPS，而不是低價的或***的。一般來說，應就負載設備所處理資料的重要性、各種用電設備對電源質量的要求、安裝與空間要求及其經(jīng)濟預算等因素綜合考慮，同時也要考慮UPS的重量和體積大小合適?？偟膩碚f，用戶應該考慮三個因素：即技術性能、服務保證和產品價格。 </p> <p> 先確認你需要何種類型的UPS </p> <p> 就中國目前的電力狀況而言，UPS是一種非常必要的電源保護設備，不同的用戶對UPS類型的需求也是不同的，如：重要設備須選用性能優(yōu)異，安全系數(shù)極高的在線式機種，在線式UPS功能完善，能抵抗來自電網(wǎng)上的各種侵害，如高壓、尖峰、浪涌、雜訊干擾等等，輸出純凈的電源，時刻保護您的負載。張家界愛克賽ups電源廠商UPS電源的工作電路長期工作在不正常狀態(tài)，這對于UPS電源也是有一定危害的。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="張家界愛克賽ups電源廠商,ups電源" src="https://tyunfile.71360.com/WaterMark/UploadFile/cdjwjd/637300013055019531/2070197.png"></div><p>工作原理不同</p><p>UPS不論市電是否正常，它都一直由逆變器供電，即按照“市電輸入—整流（充電）—逆變—輸出”的路程進行，只有在逆變器故障或過載時才改由旁路供電。</p><p>EPS當有市電時，市電通過KM1輸出，同時充電器對電池充電。當控制系統(tǒng)檢測到市電停電或者市電過低時，KM2閉合，逆變器工作，使切換開關切換至應急輸出狀態(tài)，向負載提供電能。</p><p>內部冗余程度不同</p><p>EPS電源逆變器冗余量大，進線柜和出線柜都在EPS內部，電機負荷有變頻啟動。機殼和導線有阻燃措施，有多路互投功，可與消防聯(lián)動。EPS電源負載一般是感性和阻性的，能夠帶電機、照明、風機、水泵等設備，為應急消防產品，是集中應急供電的**應急消防照明電源。</p><p>UPS電源的逆變器冗余相對來說較小，與消防無關，無須阻燃，無互投功能。UPS電源負載屬于容性負載，主帶設備一般是計算機，主要用于大型機房，確保不間斷供電和穩(wěn)壓的。</p><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設計不佳，在選購UPS時，應考慮功率因數(shù)問題。在數(shù)據(jù)中心建設中，隨需擴容、易維護、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。</p><div
