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(fù)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(fù)載的大小，甘肅科華ups不間斷電源，要避免負(fù)載的過大或者過小，甘肅科華ups不間斷電源，甘肅科華ups不間斷電源，過大的負(fù)載會使UPS電源長期工作在超負(fù)荷狀態(tài)從而縮短UPS電源的使用壽命;如果負(fù)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(fù)載應(yīng)該控制在50%到80%之間。實(shí)踐證明，UPS電源輸出負(fù)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(yùn)行，此時UPS電源不具備后備功能，負(fù)載所用的電源是通過電力系統(tǒng)直接供應(yīng)的。

增加電池容量。可以根據(jù)所需供電的時間長短增加電池的數(shù)量，但是采用這種方法會造成電池充電時間的相對增加，同時也會增加相應(yīng)的維護(hù)設(shè)備的數(shù)量、增大產(chǎn)品體積，造成UPS整體成本提高； </p> <p> 選購容量較大的UPS。采用這種方法不僅可以降低維修成本，如果需要擴(kuò)充負(fù)載設(shè)備，較大容量的不間斷電源仍可正常工作。 </p> <p> 不間斷電源（UPS）的容量如何計算 </p> <p> 目前市場上銷售的不間斷電源（UPS）多以VA作為容量單位。V是電壓，A是電流，V×A就等于功率，即不間斷電源的容量。例如，一臺425VA的不間斷電源，如果其輸出電壓為110V，則該UPS能夠提從的比較大電流為3.86A，超過此電流值就是超載（Overload）。另一種表示功率的方法是W，W表示實(shí)功，VA表示虛功。兩者之間的差別在于功率因數(shù)。功率因數(shù)一般在為0.6到0.8之間，若低于0.5則UPS設(shè)計不佳，在選購UPS時，應(yīng)考慮功率因數(shù)問題。 </p><p> UPS輸入輸出柜是針對UPS電源特性為UPS電源量身打造的配套產(chǎn)品，主要有UPS電源輸入（含雙電輸入）、UPS負(fù)載的輸出，UPS電源防雷、UPS手動旁路、輸入輸出檢測儀表、分輸出指示燈可以根據(jù)用戶要求配置不同的功能。有效而直觀地反映UPS的工作狀態(tài)。 </p> <p> UPS輸入輸出配電柜是電力機(jī)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(diǎn)，UPS實(shí)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。它能夠控制配電單元，機(jī)架式配電單元以及中心配電，能夠方便管理。因?yàn)閁PS裝了防雷充其量只能使配電柜中省一級防雷，但是配電當(dāng)中還是不能省略防雷裝置。</p><div
