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?？梢詫崿F(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，甘肅伊頓ups不間斷電源公司，甘肅伊頓ups不間斷電源公司,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，甘肅伊頓ups不間斷電源公司,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。 UPS實際上就是不間斷電源，UPS輸入輸出柜是針對UPS不間斷電源特性量身打造的設(shè)備。甘肅伊頓ups不間斷電源公司</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="甘肅伊頓ups不間斷電源公司,ups不間斷電源"

UPS電源以利用機內(nèi)的充電子產(chǎn)品電回路重新對蓄電池浮充10～12h以上再帶載運行。UPS電源長期處于浮充狀態(tài)而沒有放電過程，相當于處在“儲存待用”狀態(tài)。如果這種狀態(tài)持續(xù)的時間過長，造成蓄電池因“儲存過久”而失效報廢，它主要表現(xiàn)為電池內(nèi)阻增大，嚴重時內(nèi)阻可達幾Ω。 </p> <p> 人們發(fā)現(xiàn)：在室溫20℃下，存儲1個月后，電池可供使用的容量為其額定值的97%左右，如果儲存6個月不用，它的可使用容量變?yōu)轭~定容量的80%。如果儲存溫度升高，它的可使用容量還會降低。因此建議用戶比較好每隔20°C個月有意地拔掉市電輸入，讓UPS電源工作于由蓄電池向逆變器提供能量的狀態(tài)。但這種操作不宜時間過長，在負載為額定輸出的30%左右時，約放電10min即可。甘肅伊頓ups不間斷電源公司與UPS相同之處：EPS是***的后備式UPS，它的工作原理和后備式UPS一樣。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="甘肅伊頓ups不間斷電源公司,ups不間斷電源"

style="text-indent:25px"><p>后備式：具備自動穩(wěn)壓、斷電保護等功能，轉(zhuǎn)換時間10ms左右，逆變輸出的交流電是方波，結(jié)構(gòu)簡單，價格便宜；<p>互動式：具有濾波功能，抗市電干擾能力強，轉(zhuǎn)換時間小于4ms，逆變輸出為模擬正弦波，價格遠低于在線式；<p>在線式：結(jié)構(gòu)較復(fù)雜，性能完善，能夠持續(xù)不中斷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；價格高，通常應(yīng)用在關(guān)鍵計算機和網(wǎng)絡(luò)設(shè)備等對電力要求苛刻的環(huán)境中。<p>UPS的結(jié)構(gòu)<p>變電站內(nèi)UPS系統(tǒng)一般由電力UPS主機、旁路穩(wěn)壓柜、輸出饋線柜等三部分組成（小功率時也可三合一）。提高UPS系統(tǒng)的可靠性，同時降低其損耗，就成為數(shù)據(jù)中心UPS系統(tǒng)架構(gòu)演變的主旋律。</p><div

在線互動式UPS電源在變壓器抽頭切換的過程中，雙向變換器作為逆變器方式工作。蓄電池供電，因此能實現(xiàn)輸出電壓的不間斷，同樣在由市電供電到電池供電的切換過程中也能做到?jīng)]有轉(zhuǎn)換時間。在線互動式UPS電源的電路實現(xiàn)簡單，沒有單獨的充電器，帶來的是生產(chǎn)成本的降低和可靠性的提高。 </p> <p> 這類產(chǎn)品在市電供電工作時也不存在AC／DC、DC／AC的轉(zhuǎn)換，使整機效率有所提高。在線互動式UPS很好地結(jié)合了后備式UPS和在線式UPS的許多優(yōu)點，是一種很不錯的變換形式。但是由于它使用的是工頻變壓器，同樣有笨重、體積大的問題。后備式：具備自動穩(wěn)壓、斷電保護等功能，轉(zhuǎn)換時間10ms左右，逆變輸出的交流電是方波，結(jié)構(gòu)簡單，價格便宜；甘肅伊頓ups不間斷電源公司</p><p style="text-indent:25px">一般UPS逆變器輸出端并聯(lián)的電容器一方面起濾波作用，另一方面是抵消負載中的電感分量。甘肅伊頓ups不間斷電源公司</p><p> 什么叫有功功率，什么叫無功功率？ </p> <p> 有功功率指的是能使負載做功的功率，比如使燈泡發(fā)光，使電路工作等等。做功后又完全變成熱量散發(fā)到大氣中，一去不復(fù)返。 </p> <p> 無功功率指的是儲存在儲能裝置（器件）中的功率，它可以轉(zhuǎn)化為有功功率。 </p> <p> UPS效率的定義是什么？它表示什么？和功率因數(shù)是一回事嗎？ </p> <p> UPS效率的η的定義是：輸出有功功率P與輸入有功功率P’之比的百分數(shù)，即：η=（P/P’）％。它是衡量UPS功耗大小的標志。和功率因數(shù)不是一碼事。甘肅伊頓ups不間斷電源公司</p><p
