一般(ban)情(qing)況下，UPS電源(yuan)系(xi)統(tong)分為(wei)三(san)大類，為(wei)后(hou)備(bei)式(或離線)、在線互動式和雙轉換(huan)式(在線)。不同的(de)廠商會提供(gong)不同配置的(de)UPS，客戶(hu)根據自己(ji)的(de)目標(biao)、應(ying)用、和功能(neng)要(yao)求(qiu)，以及他(ta)們的(de)產品差異化的(de)愿望(wang)，選擇(ze)所需要(yao)的(de)UPS電源(yuan)。

(1) 使用 UPS 電(dian)源時，應嚴格遵守廠家的(de)產品說明書的(de)有關規定，保證 UPS 所接(jie)市電(dian)的(de)火線、零線順序符合要求(qiu)。

有的(de)(de)重慶UPS不(bu)間斷電(dian)源用瓦 (W) 或者千瓦 (kw) 來表(biao)示其輸出功率(lv)(lv)(lv)，如(ru)(ru) 500W 、 1kw 等(deng) ; 有的(de)(de) UPS 用伏(fu)安(an) (VA)或者千伏(fu)安(an) (kVA) 來表(biao)示其輸出功率(lv)(lv)(lv)大小，如(ru)(ru) 3000VA 、 5kVA 等(deng)。 VA 與 W 的(de)(de)一般換算關系為：瓦是(shi)伏(fu)安(an)的(de)(de) 0.8 倍(bei)，如(ru)(ru) 3kVA=2.4kw 。 UPS 是(shi)線負(fu)載供電(dian)用的(de)(de)，每一種 UPS 都(dou)有特(te)定(ding)的(de)(de)輸出功率(lv)(lv)(lv)能(neng)力。如(ru)(ru) 3kVA 的(de)(de) UPS ，其最大輸出功率(lv)(lv)(lv)是(shi) 3kVA 或者 2.4kw ，此時就要求(qiu)接到這臺(tai) UPS 上的(de)(de)設備的(de)(de)耗電(dian)功率(lv)(lv)(lv)總和不(bu)能(neng)超過(guo) 2.4 千瓦。

重慶(qing)UPS不(bu)(bu)間(jian)斷(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)按(an)其(qi)工作方(fang)式可分為后(hou)備(bei)(bei)式和(he)在線式兩大類，按(an)其(qi)輸出(chu)波(bo)形又可分為方(fang)波(bo)輸出(chu)和(he)正弦波(bo)輸出(chu)兩種。后(hou)備(bei)(bei)式 UPS 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)在市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)正常供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時，市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)通過交(jiao)流旁路通道再(zai)經(jing)轉換(huan)開關直(zhi)接向(xiang)負(fu)載(zai)提(ti)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，機內的(de)(de)(de)(de)逆(ni)(ni)變器處于停止工作狀態。這種 UPS 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)在實質(zhi)上(shang)(shang)相當(dang)于一臺(tai)穩壓(ya)性能極差的(de)(de)(de)(de)市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)穩壓(ya)器。它(ta)除了對(dui)(dui)市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)(de)幅度波(bo)動有所改(gai)善外，對(dui)(dui)市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)(de)頻率不(bu)(bu)穩、波(bo)形畸(ji)變以(yi)及從電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網串入的(de)(de)(de)(de)干擾等不(bu)(bu)良影(ying)響(xiang)基本(ben)上(shang)(shang)沒有任何改(gai)善。只有當(dang)市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)中斷(duan)(duan)或低(di)于 170V 時，蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池才(cai)對(dui)(dui) UPS 的(de)(de)(de)(de)逆(ni)(ni)變器供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，并向(xiang)負(fu)載(zai)提(ti)供穩壓(ya)、穩頻的(de)(de)(de)(de)交(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。后(hou)備(bei)(bei)式 UPS 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)(de)(de)優(you)點(dian)是運行效率高、噪音低(di)、價格相對(dui)(dui)便宜，主要適用于市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)波(bo)動不(bu)(bu)大、對(dui)(dui)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)質(zhi)量要求不(bu)(bu)高的(de)(de)(de)(de)場合。

UPS 是(shi)(shi)不間斷電(dian)源(yuan) ; 的英文名稱的縮(suo)寫，它伴隨(sui)著計算機的誕(dan)生而(er)出現，是(shi)(shi)計算機常用(yong)的外圍設備之一(yi)。實(shi)際上， UPS 是(shi)(shi)一(yi)種含(han)有儲能裝置，并以(yi)逆變器為主要(yao)組成部分的恒(heng)(heng)壓恒(heng)(heng)額的不間斷電(dian)源(yuan)。

;重慶UPS不間斷電(dian)源外接蓄電(dian)池內部短路的原因主要有(you)以下幾(ji)個方面：

在電(dian)(dian)池充放電(dian)(dian)過程(cheng)中(zhong)(zhong)，因為電(dian)(dian)解(jie)和蒸發，電(dian)(dian)解(jie)質(zhi)(zhi)中(zhong)(zhong)的水會逐漸減少，造成(cheng)電(dian)(dian)解(jie)質(zhi)(zhi)液位降低。不(bu)能(neng)用飲用純凈(jing)水取代，由于純凈(jing)水含(han)有多種微量(liang)元素，會讓(rang)蓄電(dian)(dian)池造成(cheng)不(bu)良影(ying)響。

家用電(dian)(dian)器可分為:四(si)(si)向電(dian)(dian)動(dong)、電(dian)(dian)動(dong)拖拉機(ji)(ji)、手(shou)持平(ping)衡重、電(dian)(dian)動(dong)油桶堆(dui)垛機(ji)(ji)、四(si)(si)支點(dian)堆(dui)垛機(ji)(ji)、四(si)(si)支點(dian)寬腿堆(dui)垛機(ji)(ji)、叉籃堆(dui)垛機(ji)(ji)、四(si)(si)支點(dian)兩(liang)層堆(dui)垛機(ji)(ji)。

當(dang)導出電(dian)能耗光時(shi)，必須補充電(dian)流，不然重慶蓄(xu)電(dian)池就不工作，活性(xing)物(wu)質就會(hui)脫落(luo)。正常電(dian)流應與蓄(xu)電(dian)池成(cheng)一定比例，如48v200ah，0.07倍的容量能夠滿足基本要求(qiu)。假如電(dian)流超過(guo)這個(ge)值，就會(hui)過(guo)充，電(dian)池電(dian)解(jie)液揮發(fa)得(de)太快。

鋰電(dian)池具有充(chong)電(dian)速度快、使(shi)用壽命長的優勢(shi)。重(zhong)慶蓄電(dian)池特點如(ru)下：
