對(duì)于UPS電源長(zhǎng)期處于市電低電壓供電或頻繁停電的用戶來(lái)說(shuō)，為防止電池因長(zhǎng)期充電不足而過(guò)早損壞，應(yīng)充分利用供電高峰(如深夜時(shí)間)對(duì)電池充電以保證電池在每次放電之后有足夠的充電時(shí)間。一般電池被深度放電后，再充電至額定容量的90%至少需要10～12h左右。注意充電器的選用。 </p> <p> UPS電源用的免維護(hù)密封電池不能用可控硅式的“快速充電器”進(jìn)行充電。這是因?yàn)檫@種充電器會(huì)造成蓄電池同時(shí)處于既“瞬時(shí)過(guò)流充電”又“瞬時(shí)過(guò)壓充電的惡劣充電狀態(tài)。這種狀態(tài)會(huì)使電池可供使用容量大力下降，嚴(yán)重時(shí)會(huì)使蓄電池報(bào)廢。在采用恒壓截止型充電回路的UPS電源時(shí)，注意不要將電池電壓過(guò)低保護(hù)工作點(diǎn)調(diào)得過(guò)低，否則，在它充電初期容易產(chǎn)生過(guò)流充電。當(dāng)然，比較好選用既具有恒流，又有恒壓的充電器對(duì)其進(jìn)行充電。成都科士達(dá)ups不間斷電源公司后備式：具備自動(dòng)穩(wěn)壓、斷電保護(hù)等功能，轉(zhuǎn)換時(shí)間10ms左右，逆變輸出的交流電是方波，結(jié)構(gòu)簡(jiǎn)單，價(jià)格便宜；</p><div

在線互動(dòng)式UPS電源也被稱為3端口式UPS電源，使用的是工頻變壓器。從能量傳遞的角度來(lái)考慮，其變壓器存在3個(gè)能量流動(dòng)的端口：端口1連接市電輸入；端口2通過(guò)雙向變換器與蓄電池相連；端口3輸出。 </p> <p> 市電供電時(shí)，交流電經(jīng)端口1流入變壓器，在穩(wěn)壓電路的控制下選擇合適的變壓器抽頭接入，同時(shí)在端口2的雙向變換器的作用下借助蓄電池的能量轉(zhuǎn)換共同調(diào)節(jié)端口3上的輸出電壓，以此來(lái)達(dá)到比較好的穩(wěn)壓效果；市電掉電時(shí)，蓄電池通過(guò)雙向變換器經(jīng)端口2給變壓器供電，維持端口3上的交流輸出。

當(dāng)市電電壓時(shí)高時(shí)低，UP電源內(nèi)的穩(wěn)壓器(AVR)使市電電壓保持在可使用的安全范圍，確保設(shè)備可以正常運(yùn)行。當(dāng)高低電壓超過(guò)可使用的范時(shí)，UPS電源系統(tǒng)則將啟動(dòng)蓄電池供電，保障設(shè)備的持續(xù)運(yùn)行。 </p> <p> 諧波失真保護(hù)作用 </p>

UPS監(jiān)控系統(tǒng)的擴(kuò)展性指的是系統(tǒng)所能增加監(jiān)控對(duì)象的數(shù)目。模塊化是UPS也是UPS監(jiān)控系統(tǒng)發(fā)展的一大趨勢(shì)?？梢詫?shí)現(xiàn)容量的自由增減是UPS模塊化的一大特征,而能否實(shí)現(xiàn)多種監(jiān)控對(duì)象的自由擴(kuò)展則是UPS監(jiān)控系統(tǒng)模塊化的重要標(biāo)志。從目前機(jī)房硬件設(shè)備配置情況來(lái)看,在對(duì)UPS電源實(shí)現(xiàn)全方面監(jiān)控的基礎(chǔ)上,再實(shí)現(xiàn)對(duì)環(huán)境溫濕度、漏水、門禁、電池組等對(duì)象進(jìn)行按需擴(kuò)展監(jiān)控,是UPS用戶很為迫切的需求。

由于系統(tǒng)的擴(kuò)展性是在原有的監(jiān)控平臺(tái)上進(jìn)行的(無(wú)需更換平臺(tái)),用戶可以在不同的階段,按需擴(kuò)展系統(tǒng)的監(jiān)控功能。這樣便可增強(qiáng)用戶的投入彈性,大力地降低了系統(tǒng)升級(jí)所帶來(lái)的風(fēng)險(xiǎn),同時(shí)從長(zhǎng)遠(yuǎn)來(lái)看也為UPS用戶節(jié)約了投入成本。當(dāng)然由于擴(kuò)展性的強(qiáng)弱一般是和成本直接掛勾的,這種成本在投入初期會(huì)比較明顯,所以在選購(gòu)UPS電源監(jiān)統(tǒng)系統(tǒng)時(shí)不要一味地追求擴(kuò)展功能的比較大化,而應(yīng)按“滿足現(xiàn)在,留足未來(lái)”的原則進(jìn)行。成都科士達(dá)ups不間斷電源公司</p><p
