將市電穩(wěn)壓后供應(yīng)給負(fù)載使用，此時(shí)的UPS就是一臺(tái)交流市電穩(wěn)壓器，同時(shí)它還向機(jī)內(nèi)電池充電;當(dāng)市電中斷(事故停電)時(shí)， UPS 立即將機(jī)內(nèi)電池的電能，通過逆變轉(zhuǎn)換的方法向負(fù)載繼續(xù)供應(yīng)220V交流電，使負(fù)載維持正常工作并保護(hù)負(fù)載軟、硬件不受損壞。UPS 設(shè)備通常對(duì)電壓過大和電壓太低都提供保護(hù)。</p><p

style="text-indent:25px">從專業(yè)的角度說，看一臺(tái)UPS的好與不好，較客觀和較可靠的方法就是用測(cè)試指標(biāo)去衡量。就拿影響電網(wǎng)供電質(zhì)量的輸入功率因數(shù)來說，尤其是在大容量范圍時(shí)，一般傳統(tǒng)雙變換型UPS的標(biāo)配功率因數(shù)大都在0.8左右，這就造成了約有30%的諧波電流對(duì)電網(wǎng)的*，其結(jié)果是使該電網(wǎng)上的變壓器、電纜、保險(xiǎn)絲和開關(guān)等設(shè)備發(fā)熱、疲勞。若要改變這種狀況就必須在前面加諧波濾波器或改6脈沖整流為12脈沖整流，但這又會(huì)帶來兩個(gè)副作用：一個(gè)是增加包括UPS在內(nèi)的電源保護(hù)設(shè)備的成本和體積重量，另一方面增加了UPS的損耗，從而降低了可靠性。UPS不間斷電源電源系統(tǒng)輸出為一段交流母線，全部負(fù)載電源均從該母線上饋線開關(guān)接取。蘇州單相UPS不間斷電源價(jià)格</p><p
