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(guò)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(guò)**串口控制電纜，將UPS電源連接電腦上，再通過(guò)RS232與RS485兩種協(xié)議通訊，就可實(shí)現(xiàn)UPS電源無(wú)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(guò)25度，每升高10度，電池的壽命就要縮短一半。新余UHA1R-0100不間斷電源ups維修上門維修南昌穎頓科技有限公司充滿熱情，真誠(chéng)服務(wù)。</p><div

因此一些UPS電源維護(hù)小常識(shí)就顯得特別的重要，如：防止機(jī)箱里面灰塵堆積，定期保養(yǎng)電源里面的蓄電池等等，這些維護(hù)小常識(shí)往往能極大地延長(zhǎng)UPS電源的使用壽命，減少維修麻煩。（2）保持適宜的環(huán)境溫度：影響蓄電池壽命的重要因素是環(huán)境溫度，一般電池生產(chǎn)廠家要求的比較好環(huán)境溫度是在20－25℃之間。雖然溫度的升高對(duì)電池放電能力有所提高，但付出的代價(jià)卻是電池的壽命**縮短。據(jù)試驗(yàn)測(cè)定，環(huán)境溫度一旦超過(guò)25℃，每升高10℃，電池的壽命就要縮短一半。達(dá)不到規(guī)定的環(huán)境要求，其壽命的長(zhǎng)短就有很大的差異。另外，環(huán)境溫度的提高，會(huì)導(dǎo)致電池內(nèi)部化學(xué)活性增強(qiáng)，從而產(chǎn)生大量的熱能，又會(huì)反過(guò)來(lái)促使周圍環(huán)境溫度升高，這種惡性循環(huán)，會(huì)加速縮短電池的壽命。（3）定期充電放電：UPS電源中的浮充電壓和放電電壓，在出廠時(shí)均已調(diào)試到額定值，而放電電流的大小是隨著負(fù)載的增大而增加的，使用中應(yīng)合理調(diào)節(jié)負(fù)載，比如控制微機(jī)等電子設(shè)備的使用臺(tái)數(shù)。一般情況下，負(fù)載不宜超過(guò)UPS額定負(fù)載的60%。在這個(gè)范圍內(nèi)，電池的放電電流就不會(huì)出現(xiàn)過(guò)度放電。UPS因長(zhǎng)期與市電相連，在供電質(zhì)量高、很少發(fā)生市電停電的使用環(huán)境中，蓄電池會(huì)長(zhǎng)期處于浮充電狀態(tài)。</p><p> 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。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。南昌穎頓科技有限公司不斷創(chuàng)新，積極開拓。</p><div
