故障分析與維修：從故障現(xiàn)象可知，該故障是因電池電壓太低引起。打開(kāi)機(jī)蓋，測(cè)得電池兩端電壓只有，加上市電后兩端電壓不變，說(shuō)明故障出在充電電路。該充電電路工作原理是：市電工作時(shí)，主變壓器T3輸出25V的交流電壓，經(jīng)S2繼電器的第1、2腳接點(diǎn)后，再經(jīng)B1橋堆整流、C21、C22濾波后輸出34V的直流電壓。然后將其送至可調(diào)穩(wěn)壓器U8(MG317T)穩(wěn)壓后對(duì)蓄電池充電。用萬(wàn)用表測(cè)得C21兩端直流電壓正常，說(shuō)明故障位于濾波電路后。當(dāng)測(cè)量MG317T輸出腳時(shí)，發(fā)現(xiàn)輸出電壓只有10V，查輸出負(fù)載均正常，調(diào)整VR3，輸出電壓不變化，說(shuō)明U8已損壞。用同型號(hào)的MG317T更換U8，斷開(kāi)電池，調(diào)整VR3，使得U8輸出電壓穩(wěn)定在28V左右。開(kāi)機(jī)試運(yùn)行，故障排除。故障現(xiàn)象四：市電中斷時(shí)，逆變器不工作，蜂鳴器長(zhǎng)鳴。故障分析與維修：蜂鳴器長(zhǎng)鳴，說(shuō)明該穩(wěn)壓電源的轉(zhuǎn)換控制電路正常，逆變器不工作是因保護(hù)電路動(dòng)作所致。用萬(wàn)用表檢測(cè)電池電壓正常，說(shuō)明故障出在逆變回路。該機(jī)逆變回路由脈寬調(diào)制器U1(SG3524)、取樣變壓器T2、推動(dòng)管Q5、Q6和逆變管Q17、Q18等組成。首先測(cè)量脈寬調(diào)制器U1(SG3524)的第10腳，看是否被鎖定(鎖定時(shí)為高電平)，接著測(cè)逆變管Q17、Q18靜態(tài)工作時(shí)對(duì)地的阻值。新余C6K不間斷電源ups維修來(lái)電咨詢南昌穎頓科技有限公司講實(shí)話，干實(shí)事，求實(shí)效。</p><div

用萬(wàn)用表測(cè)穩(wěn)壓電源得知C21兩端直流電壓正常，說(shuō)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(shuō)明U8已損壞。用同型號(hào)的MG317T更換U8，斷開(kāi)電池，調(diào)整VR3，使得U8輸出電壓穩(wěn)定在28v左右。開(kāi)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(wàn)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(wú)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。南昌穎頓科技有限公司勤勞，勤儉，勤奮。新余C6K不間斷電源ups維修來(lái)電咨詢</p><p
