用萬用表測穩(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)測量MG317T輸出腳時，發(fā)現(xiàn)輸出電壓只有110v，查輸出負載均正常，調(diào)整VR3輸出電壓不變化，此時說明U8已損壞。用同型號的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。開機試運行，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)電源的高壓保護電路和市電穩(wěn)壓電路出現(xiàn)故障時，才會出現(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，輸出腳4才會跳變成低電平，從而控制保護電路動作。以下分兩步進行檢測：1.高壓保護電路的檢測首先用萬用表測得電壓比較器U7的8腳電壓為、9腳電壓為，此時高壓保護電路不起動。逐一仔細查看高壓保護電路的每一器件，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，高壓保護電路起動。由此可知，電源高壓保護電路的電壓偏高，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。九江UL33-0800L不間斷電源ups維修上門服務(wù)南昌穎頓科技有限公司挑戰(zhàn)機遇，共圖發(fā)展大業(yè)。</p><div

而后備式的UPS電源的負載量應(yīng)該控制在60%～70%。注意，過度輕載也不好，雖然不如過載那么嚴(yán)重。4、不要使用柴油發(fā)電機：UPS電源不宜由柴油發(fā)電機供電，因其頻率經(jīng)常突變不穩(wěn)，影響UPS電源的正常運行。5、使用UPS電源時的開機和關(guān)機順序：正確的開**機順序應(yīng)該是先打開UPS電源給它供電，然后再打開各個負載，這樣可以避免啟動時瞬間的電流沖擊給UPS造成的損害，在關(guān)機時的順序正好相反應(yīng)該先關(guān)閉各個負載***關(guān)閉UPS.在市電中斷由UPS供電時，應(yīng)該盡快保存好自己的數(shù)據(jù)和資料然后關(guān)閉電腦，否則使用UPS電源進行工作可能會使UPS過量放電，從而縮短UPS的使用壽命。6、UPS電源***充電技巧：新購置UPS電源后，要將UPS電源插入220V市電電網(wǎng)中，充電至少12小時以上，以確保電池充電充分。否則，蓄電池的實際可供使用的容量將**低于蓄電池的標(biāo)稱容量。若UPS電源長期不用。應(yīng)每隔2～3個月開機24小時，讓其充電充分，并讓UPS電源處于逆變器工作狀態(tài)下2～3分鐘，以保證電池的正常壽命。UPS電源一旦接通市電，即開始對電池組充電，持續(xù)按開機鍵1秒以上進行開機，即開啟逆變器。7、UPS電源不可長期閑置：蓄電池的過度放電和蓄電池長期開路閑置不用可使蓄電池的內(nèi)阻增大。南昌穎頓科技有限公司率先垂范，廉潔奉公。九江UL33-0800L不間斷電源ups維修上門服務(wù)</p><p
