UPS，即不間斷電源，是將蓄電池（多為鉛酸免維護蓄電池）與主機相連接，通過主機逆變器等模塊電路將直流電轉(zhuǎn)換成市電的系統(tǒng)設(shè)備。主要用于給單臺計算機、計算機網(wǎng)絡系統(tǒng)或其它電力電子設(shè)備如電磁閥、壓力變送器等提供穩(wěn)定、不間斷的電力供應。當市電輸入正常時，UPS 將市電穩(wěn)壓后供應給負載使用，此時的UPS就是一臺交流市電穩(wěn)壓器，同時它還向機內(nèi)電池充電；當市電中斷（停電事情）時， UPS 立即將電池的直流電能，通過逆變零切換轉(zhuǎn)換的方法向負載繼續(xù)供應220V交流電，使負載維持正常工作并保護負載軟、硬件不受損壞。UPS 設(shè)備通常對電壓過高或電壓過低都能提供保護。 </p> <p> <br /> </p><p> 無故障工作時間。由于微處理器監(jiān)控技術(shù)和先進的IGBT驅(qū)動型SPWM等高技術(shù)的采用，目前的UPS已達到了極高的可靠性水平，對于大型UPS電源來講，其單機的年均無故障工作時間(MTBF)已超過20萬小時。如果采用雙總線輸出的多機“冗余”型UPS供電系統(tǒng)，其MTBF甚至可達1000萬小時數(shù)量級。 </p> <p> 南昌穎頓科技有限公司一直致力于用戶設(shè)計電力保護及機房電源解決方案。提供質(zhì)量的電源產(chǎn)品和技術(shù)服務及售后平臺，使用戶的關(guān)鍵設(shè)備得到安全、可靠的電力保障。 </p> <p> <br /> 南昌穎頓科技有限公司率先垂范，廉潔奉公。</p><div style="width:100%;text-align: center;"><img

實踐證明：對于絕大多數(shù)UPS電源而言，將其負載控制在50%~60%額定輸出功率范圍內(nèi)是較佳工作方式。禁止超負載使用，廠家建議：UPS電源的較大啟動負載好控制在80%之內(nèi)，如果超載使用，在逆變狀態(tài)下，時常會擊穿逆變?nèi)龢O管。不宜過度輕載運行，這種情況容易因為電池放電電流過小造成電池失效。 </p> <p> 定期對UPS電源進行維護工作：觀察工作指示燈狀態(tài)、除塵，測量蓄電池電壓，更換不合格電池，檢查風扇運轉(zhuǎn)情況及檢測調(diào)節(jié)UPS的系統(tǒng)參數(shù)等。 </p> <p> [<span style="font-size:12px;">UPS電源比較適合于帶微電容性負載，不適合于帶電感性負載，如空調(diào)、電動機、電鉆、風機等。如果UPS電源負載為電阻性或電感性負載時，必須酌情減小其負載量以免超載運行</span> </p> <p> <br /> 南昌穎頓科技有限公司嚴守職業(yè)道德，搞好質(zhì)量服務。在線式ups電源廠家價格</p><p

蓄電池：蓄電池是UPS用來作為儲存電能的裝置，它由若干個電池串聯(lián)而成，其容量大小決定了其維持放電（供電）的時間。其主要功能是：1當市電正常時，將電能轉(zhuǎn)換成化學能儲存在電池內(nèi)部。2當市電故障時，將化學能轉(zhuǎn)換成電能提供給逆變器或負載； </p> <p> 逆變器：通俗的講，逆變器是一種將直流電（DC）轉(zhuǎn)化為交流電（AC）的裝置。它由逆變橋、控制邏輯和濾波電路組成； </p> <p> 靜態(tài)開關(guān)：靜態(tài)開關(guān)又稱靜止開關(guān)，它是一種無觸點開關(guān)，是用兩個可控硅（SCR）反向并聯(lián)組成的一種交流開關(guān)，其閉合和斷開由邏輯控制器控制。分為轉(zhuǎn)換型和并機型兩種。轉(zhuǎn)換型開關(guān)主要用于兩路電源供電的系統(tǒng)，其作用是實現(xiàn)從一路到另一路的自動切換；并機型開關(guān)主要用于并聯(lián)逆變器與市電或多臺逆變器。
