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(biāo)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(jìn)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(jìn)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(yuǎn)來看也為UPS用戶節(jié)約了投入成本。當(dāng)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(jìn)行。 </p><p> 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(dāng)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(yán)重時內(nèi)阻可達(dá)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(fù)載為額定輸出的30%左右時，約放電10min即可。還有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)。</p><div

監(jiān)控系統(tǒng)和遠(yuǎn)方通信系統(tǒng)對變電站十分重要，因此作為電源的UPS系統(tǒng)的可靠性也有非常高的要求； </p> <p> 綜自系統(tǒng)的負(fù)載大多數(shù)為單相負(fù)載，因此電力系統(tǒng)**的UPS電源大多數(shù)要求為三相/單相輸入、單相輸出的中小型功率UPS，容量一般在60kVA范圍之內(nèi)； </p> <p> 旁路靜態(tài)切換開關(guān)應(yīng)具有自動、手動兩種工作方式，實現(xiàn)無間斷切換； </p> <p> 由于變電站有220V或110V直流系統(tǒng)，并有直流充電屏給蓄電池充電。所以電力**UPS自身不帶蓄電池，直接使用直流系統(tǒng)作為UPS的直流輸入，并且不需要具備充電功能； </p> <p> 電力**UPS的直流輸入端一般要求裝有反灌雜訊控制器，如逆止二極管等，使UPS對直流母線的影響盡量小； </p> <p> UPS電源在帶滿全部設(shè)備后，應(yīng)留有40%以上的供電容量。UPS在交流電失電后，不間斷供電維持時間不小于60分鐘。宜賓華為ups不間斷電源廠家</p><p
