發(fā)展UPS技術(shù)的主要目的是提高UPS對(duì)輸出端負(fù)載的動(dòng)態(tài)響應(yīng)越來越快又好。顯然，采用先進(jìn)的高頻技術(shù)，動(dòng)態(tài)響應(yīng)速度很快，效果比較好。 </p> <p> 傳統(tǒng)工頻機(jī)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(jī)的輸出隔離變壓器嚴(yán)格講是它逆變部分不可或缺的組件，沒有全隔離效果，因?yàn)榕月窡o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(jí)防雷，它有兩種方式： </p> <p> 以保護(hù)負(fù)載為優(yōu)先的防雷； </p> <p> 以保護(hù)供電為優(yōu)先的防雷，但是作用不大。因?yàn)閁PS裝了防雷充其量只能使配電柜中省一級(jí)防雷，重慶科華ups不間斷電源公司，重慶科華ups不間斷電源公司，重慶科華ups不間斷電源公司，但是配電當(dāng)中還是不能省略防雷裝置。提高UPS系統(tǒng)的可靠性，同時(shí)降低其損耗，就成為數(shù)據(jù)中心UPS系統(tǒng)架構(gòu)演變的主旋律。重慶科華ups不間斷電源公司</p><div

對(duì)于UPS電源長(zhǎng)期處于市電低電壓供電或頻繁停電的用戶來說，為防止電池因長(zhǎng)期充電不足而過早損壞，應(yīng)充分利用供電高峰(如深夜時(shí)間)對(duì)電池充電以保證電池在每次放電之后有足夠的充電時(shí)間。一般電池被深度放電后，再充電至額定容量的90%至少需要10～12h左右。注意充電器的選用。 </p> <p> UPS電源用的免維護(hù)密封電池不能用可控硅式的“快速充電器”進(jìn)行充電。這是因?yàn)檫@種充電器會(huì)造成蓄電池同時(shí)處于既“瞬時(shí)過流充電”又“瞬時(shí)過壓充電的惡劣充電狀態(tài)。這種狀態(tài)會(huì)使電池可供使用容量大力下降，嚴(yán)重時(shí)會(huì)使蓄電池報(bào)廢。在采用恒壓截止型充電回路的UPS電源時(shí)，注意不要將電池電壓過低保護(hù)工作點(diǎn)調(diào)得過低，否則，在它充電初期容易產(chǎn)生過流充電。當(dāng)然，比較好選用既具有恒流，又有恒壓的充電器對(duì)其進(jìn)行充電。重慶科華ups不間斷電源公司輸出電壓、頻率范圍小，則表明對(duì)市電調(diào)整能力強(qiáng)，輸出穩(wěn)定。</p><div

style="text-indent:25px"><p>UPS的電池管理<p>電池是UPS的重要組成部分，在UPS的諸多故障中，有很大比例是由于電池問題引起的，電池性能的好壞直接影響到系統(tǒng)的可靠性。為了保證電池的服務(wù)壽命，除了維持正常溫度和日常的維護(hù)外，電池的自動(dòng)管理是至關(guān)重要的因素。<p>UPS電源對(duì)電池自動(dòng)管理包括自動(dòng)均浮充轉(zhuǎn)換控制、電池預(yù)告警關(guān)機(jī)、定期自動(dòng)維護(hù)、手動(dòng)電池自檢等多項(xiàng)可提高電池使用壽命的先進(jìn)功能，同時(shí)還具備電池故障檢測(cè)、電池放電后備時(shí)間預(yù)測(cè)及電池特征曲線管理。</p><p> 凈化功能由儲(chǔ)能電池來完成，由于整流器對(duì)瞬時(shí)脈沖干擾不能消除，整流后的電壓仍存在干擾脈沖。儲(chǔ)能電池除可存儲(chǔ)直流直能的功能外，對(duì)整流器來說就像接了一只大容器電容器，其等效電容量的大小，與儲(chǔ)能電池容量大小成正比。由于電容兩端的電壓是不能突變的，即利用了電容器對(duì)脈沖的平滑特性消除了脈沖干擾，起到了凈化功能，也稱對(duì)干擾的屏蔽。 </p> <p> 頻率的穩(wěn)定則由變換器來完成，頻率穩(wěn)定度取決于變換器的振蕩頻率的穩(wěn)定程度。為方便UPS電源系統(tǒng)的日常操作與維護(hù)，設(shè)計(jì)了系統(tǒng)工作開關(guān)，主機(jī)自檢故障后的自動(dòng)旁路開關(guān)，檢修旁路開關(guān)等開關(guān)控制。
