凈化功能由儲能電池來完成，由于整流器對瞬時脈沖干擾不能消除，整流后的電壓仍存在干擾脈沖。儲能電池除可存儲直流直能的功能外，對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，即利用了電容器對脈沖的平滑特性消除了脈沖干擾，起到了凈化功能，也稱對干擾的屏蔽。 </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，設(shè)計了系統(tǒng)工作開關(guān)，主機自檢故障后的自動旁路開關(guān)，檢修旁路開關(guān)等開關(guān)控制。 </p><p> UPS按工作原理分成后備式、在線式與在線互動式三大類; </p> <p> 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 style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="雅安山特ups不間斷電源公司,ups不間斷電源"

使用UPS電源后，不必再加交流穩(wěn)壓器。若一定要加，應(yīng)加在UPS電源的前級，即市電先經(jīng)交流穩(wěn)壓器，再經(jīng)UPS電源，然后到負載。 </p> <p> 避免過載使用UPS電源 </p> <p> 在使用UPS電源的時候還要計算負載的大小，要避免負載的過大或者過小，過大的負載會使UPS電源長期工作在超負荷狀態(tài)從而縮短UPS電源的使用壽命;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。合理的負載應(yīng)該控制在50%到80%之間。實踐證明，UPS電源輸出負載控制在60%左右為比較好，可靠性比較好。在UPS電源出現(xiàn)過載或逆變器故障時會轉(zhuǎn)到旁路模式運行，此時UPS電源不具備后備功能，負載所用的電源是通過電力系統(tǒng)直接供應(yīng)的。

監(jiān)控系統(tǒng)和遠方通信系統(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)的負載大多數(shù)為單相負載，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??； </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。雅安山特ups不間斷電源公司</p><p
