用萬用表測(cè)穩(wěn)壓電源得知C21兩端直流電壓正常，說明故障發(fā)生在濾波電路之后。當(dāng)測(cè)量MG317T輸出腳時(shí)，發(fā)現(xiàn)輸出電壓只有110v，查輸出負(fù)載均正常，調(diào)整VR3輸出電壓不變化，此時(shí)說明U8已損壞。用同型號(hào)的MG317T更換U8，斷開電池，調(diào)整VR3，使得U8輸出電壓穩(wěn)定在28v左右。開機(jī)試運(yùn)行，故障排除。三特500VAUPS穩(wěn)壓電源故障維修四則故障現(xiàn)象一：市電供電正常，逆變時(shí)有輸出，但輸出電壓偏高，升至265V。故障分析與維修：根據(jù)UPS電源工作原理可知，只有當(dāng)電源的高壓保護(hù)電路和市電穩(wěn)壓電路出現(xiàn)故障時(shí)，才會(huì)出現(xiàn)以上故障。從電路圖一中可知，電源輸出電壓經(jīng)T2取樣、整流、濾波后，加至電壓比較器U7的8腳、9腳，然后接參考電壓端。只有當(dāng)8腳電壓高于9腳電壓時(shí)，輸出腳4才會(huì)跳變成低電平，從而控制保護(hù)電路動(dòng)作。以下分兩步進(jìn)行檢測(cè)：1.高壓保護(hù)電路的檢測(cè)首先用萬用表測(cè)得電壓比較器U7的8腳電壓為、9腳電壓為，此時(shí)高壓保護(hù)電路不起動(dòng)。逐一仔細(xì)查看高壓保護(hù)電路的每一器件，均無故障。適當(dāng)調(diào)整電位器RP8，當(dāng)下調(diào)至某一數(shù)值時(shí)，高壓保護(hù)電路起動(dòng)。由此可知，電源高壓保護(hù)電路的電壓偏高，須重新調(diào)整。將電源的輸入端接在交流調(diào)壓器上，輸出端接在電壓表上。</p><p> 放電20%，均充浮充自動(dòng)切換，充分活化鉛酸分子，**延長(zhǎng)電池壽命。我們廠做個(gè)測(cè)試蓄電池放電20%，留80%可以循環(huán)放電1500-2500次，蓄電池**放電；②放電時(shí)恒定檢測(cè)每個(gè)電池組，監(jiān)測(cè)每一塊電池的電壓、電流、溫度，根據(jù)電池溫度調(diào)節(jié)電池電壓進(jìn)行補(bǔ)償；③電池放電記錄日志防止電池失效診斷；④充電電流按，電流可以1至100A設(shè)定。9、作好實(shí)時(shí)監(jiān)控：目前智能UPS電源都具備與微機(jī)通訊和程序控制等可操作性能特性。在微機(jī)上安裝相應(yīng)的軟件，通過串/并口連接UPS電源，運(yùn)行該程序，就可以利用微機(jī)與UPS電源進(jìn)行通訊。一般具有信息查詢、參數(shù)設(shè)置、定時(shí)設(shè)定、自動(dòng)關(guān)機(jī)和報(bào)警等功能。如Winpower.然后通過**串口控制電纜，將UPS電源連接電腦上，再通過RS232與RS485兩種協(xié)議通訊，就可實(shí)現(xiàn)UPS電源無市電輸入且低電量時(shí)自動(dòng)關(guān)機(jī)的功能了。且它可同時(shí)監(jiān)控個(gè)串口上所連接的多臺(tái)UPS電源。10、合理選擇UPS電源安裝位置一個(gè)好的安裝位置非常重要，放置UPS的地方必須具備良好的通風(fēng)效果，要遠(yuǎn)離水、可燃性氣體和腐蝕劑，環(huán)境溫度保持在0～40℃之間，若是在低溫下拆裝使用，可能會(huì)有水滴凝結(jié)現(xiàn)象。環(huán)境溫度一旦超過25度，每升高10度，電池的壽命就要縮短一半。南昌穎頓科技有限公司講實(shí)話，干實(shí)事，求實(shí)效。</p><div
