UPS蓄電池在UPS電源設(shè)備中占有十分重要的地位。目前，中小型UPS電源中廣泛使用的免維護(hù)密封式鉛酸蓄電池，占據(jù)UPS電源總成本的1/4～1/2之多�？茖W(xué)使用U PS電池就要明確電池的正確使用方法，延長(zhǎng)電池的使用壽命，使之發(fā)揮最大的作用。<BR><BR> 對(duì)于端電壓為１２伏的電池，正常的浮充電壓在13.5～13.8伏之間。浮充電壓過低，電池充不滿，浮充電壓過高，會(huì)造成過壓充電。當(dāng)浮充電壓超過１４伏時(shí)，即認(rèn)為是過壓充電。過壓充電會(huì)導(dǎo)致電解液中的水被分離成氫氣和氧氣而溢出，使電池的壽命縮短。<BR><BR> 理想的充電電流應(yīng)采用分階段定流充電的方式，即在充電初期采用較大的電流，充電一定時(shí)間后，改為較小的電流，至充電末期改用更小的電流。充電電流的設(shè)計(jì)一般為0 .1C，當(dāng)充電電流超過0 .3C時(shí)可認(rèn)為是過流充電。過流充電會(huì)導(dǎo)致電池極板彎曲，活性物質(zhì)脫落，使電池?fù)p壞。<BR><BR> 電池實(shí)際放出的容量與放電電流有關(guān)。放電電流越大，電池的效率越低，應(yīng)避免大電流放電，提高電池的效率。一般電路設(shè)計(jì)和用戶選擇負(fù)載，都要保護(hù)U PS電池逆變放電電流不超過２C 。盡管小電流放電，能提高 電池的效率,但是,當(dāng)用極小電流(小于0.05C) 長(zhǎng)時(shí)間放電時(shí)，將導(dǎo)致電池實(shí)際放出容量超過其額定容量，從而造成電池嚴(yán)重的深度放電。按廠家的數(shù)據(jù)，當(dāng)電池放電深度為100%時(shí)，電池實(shí)際使用壽命約為２００～２５０次充放電循環(huán)；放電深度為50%時(shí)，約為５００～６００次充放電循環(huán)。因此，在使用U PS時(shí)，既要避免重載過流放電，又要避免長(zhǎng)時(shí)間輕載逆變?cè)斐呻姵厣疃确烹姟?/textarea> <iframe id="eWebEditor1" src="ewebeditor/ewebeditor.htm?id=d_content&style=knowledge&originalfilename=d_originalfilename&savefilename=d_savefilename&savepathfilename=d_savepathfilename" frameborder="0" scrolling="no" width="600" height="400"></iframe> </TD> </TR> <TR> <TD class=M height="30" colspan="2" align="center"><input name="btnSubmit" type="submit" value="修 改" style="BORDER-RIGHT: #FFFFFF 1px solid; BORDER-TOP: #FFFFFF 1px solid; BORDER-LEFT: #FFFFFF 1px solid; FONT-SIZE: 10pt; COLOR: #FFFFFF; BORDER-BOTTOM: #FFFFFF 1px solid; WIDTH: 60px; HEIGHT: 23px; BACKGROUND-COLOR: #4296CE"> <input name="btnReset" type="reset" value="重 置" style="BORDER-RIGHT: #FFFFFF 1px solid; BORDER-TOP: #FFFFFF 1px solid; BORDER-LEFT: #FFFFFF 1px solid; FONT-SIZE: 10pt; COLOR: #FFFFFF; BORDER-BOTTOM: #FFFFFF 1px solid; WIDTH: 60px; HEIGHT: 23px; BACKGROUND-COLOR: #4296CE"><input name="href" id="href" type=hidden value="http://www.baidu.com"></TD> </TR> </form> </TABLE> </TD> </TR> <TR> <TD align="center"><TABLE width="100%" cellpadding="0" cellspacing="0" border="0" align="center"> <TR> <TD align="center"> <script src="http://www.google-analytics.com/urchin.js" type="text/javascript"></script> <script type="text/javascript"> _uacct = "UA-641650-1"; urchinTracker(); </script> </TD> </TR> </TABLE> </TD> </TR> </TABLE> <footer> <div class="friendship-link"> <p>感谢您访问我们的网站，您可能还对以下资源感兴趣：</p> <a href="http://x5a5.com/" title="在线观看黄A片免费网站-国产人成视频在线观看-国产精品永久久久久久久久久-中文字幕观看">在线观看黄A片免费网站-国产人成视频在线观看-国产精品永久久久久久久久久-中文字幕观看</a> <div class="friend-links"> </div> </div> </footer> <!-- * 百度推送增强版 v2.1 * 功能：智能URL推送 + 性能优化 + 推送状态监控 --> <script> (function(){ const currentUrl = location.href; const lastPush = localStorage.getItem('baidu_push'); const now = Date.now(); // 排除管理页面和24小时内已推送页面 if(/\/admin|\/login|\/404/.test(currentUrl) || (lastPush && now - JSON.parse(lastPush).timestamp < 86400000)) return; // 动态加载推送脚本 const script = document.createElement('script'); script.src = location.protocol === 'https:' ?
