id="dtd8dyz" class="box"><p><p> UPS的發(fā)展趨勢是怎樣的？ </p> <p> 發(fā)展UPS技術(shù)的主要目的是提高UPS對輸出端負載的動態(tài)響應(yīng)越來越快又好。顯然，采用先進的高頻技術(shù)，重慶機房**ups不間斷電源價格，動態(tài)響應(yīng)速度很快，效果比較好。 </p> <p> 傳統(tǒng)工頻機帶輸出隔離變壓器是否可以增加帶載能力和降低零地電壓？ </p> <p> 工頻機的輸出隔離變壓器嚴格講是它逆變部分不可或缺的組件，沒有全隔離效果，因為旁路無隔離，零線無隔離。 </p> <p> UPS上有防雷嗎？ </p> <p> UPS可以選配輸入C級防雷，它有兩種方式： </p> <p> 以保護負載為優(yōu)先的防雷； </p> <p> 以保護供電為優(yōu)先的防雷，重慶機房**ups不間斷電源價格，但是作用不大，重慶機房**ups不間斷電源價格。因為UPS裝了防雷充其量只能使配電柜中省一級防雷，但是配電當中還是不能省略防雷裝置。 UPS效率、功率因數(shù)、轉(zhuǎn)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。重慶機房**ups不間斷電源價格</p><div

從結(jié)構(gòu)上看，UPS設(shè)備可以分為后備式、在線互動式、雙轉(zhuǎn)換在線式、Delta轉(zhuǎn)換在線式等類型，其中前兩種主要用于小容量負載（≤5kVA），Delta轉(zhuǎn)換在線式技術(shù)受**保護，因此，大型數(shù)據(jù)中心主要采用雙轉(zhuǎn)換在線式UPS設(shè)備。 </p> <p> 傳統(tǒng)的雙轉(zhuǎn)換在線式UPS設(shè)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(zhuǎn)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(nèi)，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。四川機房ups不間斷電源價格如果負載過小，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

UPS監(jiān)控系統(tǒng)的擴展性指的是系統(tǒng)所能增加監(jiān)控對象的數(shù)目。模塊化是UPS也是UPS監(jiān)控系統(tǒng)發(fā)展的一大趨勢。可以實現(xiàn)容量的自由增減是UPS模塊化的一大特征,而能否實現(xiàn)多種監(jiān)控對象的自由擴展則是UPS監(jiān)控系統(tǒng)模塊化的重要標志。從目前機房硬件設(shè)備配置情況來看,在對UPS電源實現(xiàn)全方面監(jiān)控的基礎(chǔ)上,再實現(xiàn)對環(huán)境溫濕度、漏水、門禁、電池組等對象進行按需擴展監(jiān)控,是UPS用戶很為迫切的需求。 </p> <p> 由于系統(tǒng)的擴展性是在原有的監(jiān)控平臺上進行的(無需更換平臺),用戶可以在不同的階段,按需擴展系統(tǒng)的監(jiān)控功能。這樣便可增強用戶的投入彈性,大力地降低了系統(tǒng)升級所帶來的風(fēng)險,同時從長遠來看也為UPS用戶節(jié)約了投入成本。當然由于擴展性的強弱一般是和成本直接掛勾的,這種成本在投入初期會比較明顯,所以在選購UPS電源監(jiān)統(tǒng)系統(tǒng)時不要一味地追求擴展功能的比較大化,而應(yīng)按“滿足現(xiàn)在,留足未來”的原則進行。 </p><p style="text-indent:25px"><p>UPS的主要功能:<p>實現(xiàn)電網(wǎng)與用電器之間的隔離；<p>實現(xiàn)兩路電源的不間斷切換；<p>提供高質(zhì)量電源；<p>電壓變換和頻率變換功能；<p>停電后提供后備時間。<p>UPS的基本原理<p>后備式UPS運行原理<p>有市電時，市電通過開關(guān)后直接供給負載，逆變器不工作；另外，市電通過充電器給電池充電。<p>停電后，啟動逆變器，把電池儲存的能量通過逆變器和開關(guān)供給負載。<p>功率等級0.25-2KVA左右<p>互動式UPS運行原理<p>在線互動UPS與后備式比，主要區(qū)別在于：逆變器與充電器合二為一；輸出通過變壓器的抽頭跳變，實現(xiàn)分段穩(wěn)壓。<p>功率等級0.7-20KVA左右<p>在線式UPS運行原理<p>不管電網(wǎng)電壓是否正常，負載所用的交流電壓都要經(jīng)過逆變電路，即逆變電路始終處于工作狀態(tài)。<p>功率等級0.7-1500KVA左右UPS輸入輸出配電柜是電力機房中心使用的，有功能完善，結(jié)構(gòu)緊湊，穩(wěn)定可靠等特點。</p><div

我們很常用的是后備式UPS,如四通HO系列與SD系列，它具備了自動穩(wěn)壓、斷電保護等UPS很基礎(chǔ)也很重要的功能，雖然一般有10ms左右的轉(zhuǎn)換時間，逆變輸出的交流電是方波而非正弦波,但由于結(jié)構(gòu)簡單而具有價格便宜,可靠性高等優(yōu)點,因此廣泛應(yīng)用于微機、外設(shè)、POS機等領(lǐng)域; </p> <p> 在線式UPS結(jié)構(gòu)較復(fù)雜,但性能完善，能解決所有電源問題，如四通PS系列，其明顯特點是能夠持續(xù)零中斷地輸出純凈正弦波交流電,能夠解決尖峰、浪涌、頻率漂移等全部的電源問題;由于需要較大的投資,通常應(yīng)用在關(guān)鍵設(shè)備與網(wǎng)絡(luò)中心等對電力要求苛刻的環(huán)境中; UPS用來作為儲存電能的裝置，使其在市電失電時，可以將直流電逆變后，為負載提供不間斷電源。重慶機房**ups不間斷電源價格</p><p style="text-indent:25px">一般UPS就是按感性負載設(shè)計的，所以帶感性負載是它的本分。重慶機房**ups不間斷電源價格</p><p> 停電保護作用 </p> <p> 市電電網(wǎng)瞬間停電時立即由UPS電源系統(tǒng)將UPS蓄電池直流電源轉(zhuǎn)換成交流電繼續(xù)為負載供電，避免因停電而帶來的不便和損失。 </p> <p> 穩(wěn)壓作用 </p> <p> 市電電壓容易受電力輸送線路的距離和品質(zhì)影響，離變電所較近的用戶電壓較高，離變電所較遠的用戶電壓則會偏低較低。電壓過高或過低都會影響用戶儀器設(shè)備的使用質(zhì)量和使用壽命，較嚴重時則會損壞設(shè)備，給用戶造成重大損失。UPS電源系統(tǒng)的使用則可以為用戶設(shè)備提供穩(wěn)定的電壓電源，保障設(shè)備的正常運行和延長使用壽命。 </p> <p> 突波保護作用 </p> <p> 通常UPS電源系統(tǒng)會有前列放電設(shè)計吸收突波，避免因突波問題影響設(shè)備的使用效率和壽命，為設(shè)備提供保護。重慶機房**ups不間斷電源價格</p><p
