id="w8c34wd" class="box"><p><p> UPS作為保護性的電源設備，它的性能參數(shù)具有重要意義，應是我們選購時的考慮重點。市電電壓輸入范圍寬，則表明對市電的利用能力強（減少電池放電）。輸出電壓、頻率范圍小，則表明對市電調整能力強，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)定度則說明當UPS突然由零負載加到滿負載時，輸出電壓的穩(wěn)定性。 </p> <p> 還有UPS效率、功率因數(shù)、轉換時間等都是表征UPS性能的重要參數(shù)，決定了對負載的保護能力和對市電的利用率。性能越好，保護能力也越強，總的來說，離線式UPS對負載的保護很差，在線互動式略優(yōu)之，在線式則幾乎可以解決所有的常見電力問題。當然成本也隨著性能的增強而上升。因此用戶在選購UPS時，應根據(jù)負載對電力的要求程度及負載的重要性不同,而選取不同類型的UPS，麗江科華ups不間斷電源價格，麗江科華ups不間斷電源價格，麗江科華ups不間斷電源價格。 UPS中文為“不間斷電源”。是一種含儲能裝置，以整流器、逆變器為主要組成部分。麗江科華ups不間斷電源價格</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="麗江科華ups不間斷電源價格,ups不間斷電源"

電源監(jiān)控軟件是與不間斷電源（UPS）配合使用，用以提高不間斷電源的效能。用戶在使用不間斷電源過程中，通過該軟件能夠準確掌握不間斷電源的工作狀態(tài)，記錄市電的穩(wěn)定狀況供技術人員進行分析。沁市電中斷或電池供電終止時可以自動進行文檔儲存、系統(tǒng)關閉以及關閉UPS等功能。新一代電源監(jiān)控軟件還具有UPS遠端監(jiān)控和UPS定時開關機等功能。 </p> <p> <span style="display:none;"></span>購買UPS時必須購買相應的監(jiān)控軟件嗎 </p> <p> 為了提高并有效的發(fā)揮UPS的全部效能，選擇一套UPS監(jiān)控軟件是必須的。一般用戶很希望知道的是市電輸入及電池狀態(tài)是否正常。當市電發(fā)生異常，又未安裝相應的電源監(jiān)控軟件時，如果用戶在現(xiàn)場，可以利用UPS提供的電源采取應急措施，如儲存文檔、關閉系統(tǒng)等。但是如果市電發(fā)生異常，又未安裝監(jiān)控軟件，而用戶又不在現(xiàn)場，當UPS電池供電耗盡時，輕則造成資料的流失，重則造成電腦與周邊設備內部元件損壞。因此購買UPS時，比較好同時購買電源監(jiān)控軟件來實現(xiàn)完善的電力保護。<span

從結構上看，UPS設備可以分為后備式、在線互動式、雙轉換在線式、Delta轉換在線式等類型，其中前兩種主要用于小容量負載（≤5kVA），Delta轉換在線式技術受**保護，因此，大型數(shù)據(jù)中心主要采用雙轉換在線式UPS設備。 </p> <p> 傳統(tǒng)的雙轉換在線式UPS設備采用可控硅整流，主要的問題是諧波電流畸變率（THDi）高(10-30%)，轉換效率低(85-92%)。 </p> <p> 隨著電力電子器件的發(fā)展，呈現(xiàn)出IGBT取代可控硅整流的趨勢，IGBT整流的優(yōu)勢是取消變壓器，因而降低了成本，同時有比較好的輸入特性，在較寬的負載范圍內，可以將THDi控制在5-10%之間，比較大的好處是效率的提升，通常在87-95%之間。目前，IGBT整流型UPS的可靠性比可控硅整流型略低。

當市電輸入正常時，UPS將市電穩(wěn)壓后供應給負載使用，此時的UPS就是一臺交流式電穩(wěn)壓器，同時它還向機內電池充電；當市電中斷（故障停電）時，UPS立即將電池的直流電能，通過逆變器切換轉換的方法向負載繼續(xù)供應220V交流電，使負載維持正常工作并保護負載軟、硬件不受損壞。 </p> <p> UPS
