市電有時會發(fā)生電壓上涌和下陷或瞬間壓降，這樣的問題會影響設備的精細度，嚴重時會損壞精密設備使用戶遭受損失。UPS系統(tǒng)可以提供穩(wěn)定的電壓，從而保護設備。 </p> <p> 控制橫模和共模噪聲的作用 </p> <p> 橫模噪聲產(chǎn)生在火線與中性線之間;共模噪聲產(chǎn)生在火線、中性線與地線之間。看不見的電力問題防不勝防，時時刻刻危害著儀器設備，給用戶造成損失。UPS電源為儀器和數(shù)據(jù)保駕護航，確保設備的正常運行和延長設備使用壽命。 </p> <p>

發(fā)展UPS技術的主要目的是提高UPS對輸出端負載的動態(tài)響應越來越快又好。顯然，采用先進的高頻技術，動態(tài)響應速度很快，效果比較好。 </p> <p> 傳統(tǒng)工頻機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> 工頻機的輸出隔離變壓器嚴格講是它逆變部分不可或缺的組件，沒有全隔離效果，因為旁路無隔離，零線無隔離。 </p> <p> UPS上有防雷嗎？ </p> <p> UPS可以選配輸入C級防雷，它有兩種方式： </p> <p> 以保護負載為優(yōu)先的防雷； </p> <p> 以保護供電為優(yōu)先的防雷，但是作用不大。因為UPS裝了防雷充其量只能使配電柜中省一級防雷，但是配電當中還是不能省略防雷裝置。 </p><p> 不間斷電源供電時間多長才合適 </p> <p> UPS能在電力異常時有足夠的時間實施應急措施。一般而言5-10分鐘的后備時間就足夠了。如果需要較長的后備時間，可以購買具有長延時功能的UPS。 </p> <p> 不間斷電源的容量如何計算 </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能夠提供的比較大電流為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設計不佳，在選購UPS時，應考慮功率因數(shù)問題。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="text-indent:25px">性能越好，保護能力也越強，總的來說，離線式UPS對負載的保護很差，在線互動式略優(yōu)之。張家界機房**ups不間斷電源廠商</p><p> 高低電壓保護作用 </p> <p> 當市電電壓時高時低，UP電源內(nèi)的穩(wěn)壓器(AVR)使市電電壓保持在可使用的安全范圍，確保設備可以正常運行。當高低電壓超過可使用的范時，UPS電源系統(tǒng)則將啟動蓄電池供電，保障設備的持續(xù)運行。 </p> <p> 諧波失真保護作用 </p> <p> 電力經(jīng)由輸配電線路傳送至使用端時，電壓波形失真，基波電流發(fā)生變化產(chǎn)生諧波。諧波會影響設備的使用，通過UPS電源則能為設備提供穩(wěn)定***的電源，有效提高設備的運行效率和壽命。 </p> <p> <span style="display:none;"></span>穩(wěn)定頻率作用 </p> <p> 頻率就是市電每一秒變動的周期，50Hz就是每秒50周次。市電發(fā)電機運轉(zhuǎn)時受到用戶端用電量的突然變化而造成轉(zhuǎn)速的變動將使轉(zhuǎn)換出來的電力頻率不定，通過UPS電源轉(zhuǎn)換的電力可提供穩(wěn)定的頻率，確保儀器設備的正常工作。<span style="display:none;"></span> 張家界機房**ups不間斷電源廠商</p><p
