其發(fā)展大致經(jīng)歷了三個階段：①整組電壓監(jiān)測、②單電池電壓監(jiān)測、③單電池內(nèi)阻巡檢1）整組電壓監(jiān)測整組電池監(jiān)測功能一般設計在整流電源內(nèi)，測量電池組的電壓，電流和溫度，進行充電和放電管理，尤其是根據(jù)環(huán)境溫度變化調(diào)整電池的浮充電壓，在電池放電時電池組電壓低至某下限時報警，現(xiàn)在的UPS仍然采用該方法。但是整組監(jiān)測存在較大的不足,如在蓄電池組放電時,放電的截止電壓是N×(N為蓄電池數(shù)量),但是由于蓄電池組中蓄電池的一致性無法嚴格保證，因此在放電中當個別電池已經(jīng)達到放電截止電壓，但電池組并沒有達到N×，這樣就會出現(xiàn)個別電池過放電。2）單電池電壓監(jiān)測全電子式的監(jiān)測，對蓄電池的運行情況可以作到較為***的監(jiān)測與管理，如單電池電壓、電池組電壓、充放電電流、蓄電池的環(huán)境溫度等。通過蓄電池運行參數(shù)的監(jiān)測，可以保證蓄電池在正常條件下的運行與工作。但當蓄電池運行條件無法保障的前提下，蓄電池運行參數(shù)的監(jiān)測是無法反映其性能參數(shù)的。3）單電池內(nèi)阻監(jiān)測電池總內(nèi)阻是電荷轉移電阻與各部件歐姆電阻的總和，實驗表明：歐姆阻抗是電池早期失效的比較大***。以下是**通常的影響內(nèi)阻變化的因素：腐蝕隨柵板和匯流排的腐蝕，金屬導電回路變化，使內(nèi)阻增大。</p><div

其不足之處是當容量少于10kVA以下，其整機效率不高，一般在85%左右。[5]不間斷電源技術指標編輯新型UPS中的逆變器大多采用了PWM技術，同時采用了石英晶體振蕩控制逆變器的頻率，通過電壓負反饋電路確保輸出電壓的穩(wěn)定。它具有開關電源的一系列優(yōu)點，通過精確調(diào)整脈沖寬度，保證功率穩(wěn)定輸出，同時．開關電源技術的應用，也使其自身損耗**降低。主要技術指標如下：[3]（1）額定輸出功率和比較大輸出功率；[3]（2）切換時間；[3]（3）輸出電壓穩(wěn)定度，參考值±±2%；[3]（4）輸出頻率穩(wěn)定度，參考值±±；[3]（5）輸出波形**(正弦波輸出)，電壓畸變小于1%，不存在潛波失真的問題；[3]（6）效率高、損耗低。參考指標高于90%；[3]（7）無故障工作時間。由于微處理器監(jiān)控技術和先進的IGBT驅動型SPWM等高技術的采用，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。[3]不間斷電源發(fā)展特點編輯（1）UPS采用模塊化在線并機擴容功能。目前多數(shù)大功率段的UPS均已經(jīng)具備冗余并機功能。</p><div
