UPS電源的(de)安全管理

使用新的(de)UPS電(dian)(dian)(dian)(dian)(dian)源(yuan)或UPS電(dian)(dian)(dian)(dian)(dian)源(yuan)100%全負荷放電(dian)(dian)(dian)(dian)(dian)較長(chang)的(de)時間，要把UPS插進(jin)220V市電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)網里，充電(dian)(dian)(dian)(dian)(dian)必須(xu)要超過(guo)12h以(yi)上，從而保證電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)充足(zu)(zu)。如果UPS電(dian)(dian)(dian)(dian)(dian)源(yuan)不(bu)使用的(de)時間過(guo)長(chang)，必須(xu)每(mei)兩道三個(ge)開機超過(guo)24h，從而保證充電(dian)(dian)(dian)(dian)(dian)充足(zu)(zu)，從而使UPS電(dian)(dian)(dian)(dian)(dian)源(yuan)保持逆變(bian)器工作狀(zhuang)態2～3s，以(yi)保證電(dian)(dian)(dian)(dian)(dian)池的(de)正常壽命。

     UPS過(guo)(guo)載(zai)或逆變器故(gu)障時會轉(zhuan)到(dao)旁路模式運行，UPS失去(qu)了(le)后背(bei)功(gong)能(neng)，負(fu)載(zai)所用的電(dian)(dian)源(yuan)(yuan)是(shi)電(dian)(dian)力系(xi)統(tong)供應的。如(ru)果(guo)市(shi)電(dian)(dian)指(zhi)示(shi)燈(deng)閃(shan)爍(shuo)(shuo)，說明(ming)市(shi)電(dian)(dian)的電(dian)(dian)壓或頻率高于正常范圍(wei);如(ru)果(guo)負(fu)載(zai)指(zhi)示(shi)燈(deng)超過(guo)(guo)100%，表(biao)明(ming)接(jie)了(le)過(guo)(guo)多的負(fu)載(zai)，蜂鳴(ming)器會半秒叫一(yi)次，生產分休式USP電(dian)(dian)源(yuan)(yuan)，應將不必(bi)要負(fu)載(zai)逐一(yi)去(qu)除，直到(dao)UPS負(fu)載(zai)量小于100%;若電(dian)(dian)池指(zhi)示(shi)燈(deng)閃(shan)爍(shuo)(shuo)，USP電(dian)(dian)源(yuan)(yuan)，則表(biao)示(shi)UPS未接(jie)電(dian)(dian)池或電(dian)(dian)池電(dian)(dian)壓太低，此時應檢查電(dian)(dian)池是(shi)否(fou)連接(jie)好，機架式三三USP電(dian)(dian)源(yuan)(yuan)，如(ru)果(guo)連接(jie)是(shi)正確的，那么有可(ke)能(neng)是(shi)蓄(xu)電(dian)(dian)池故(gu)障或者蓄(xu)電(dian)(dian)池老(lao)化。

      直(zhi)流(liu)(liu)(liu)穩壓(ya)電(dian)(dian)壓(ya)電(dian)(dian)源的(de)(de)設(she)計思路是將220V，50HZ交(jiao)流(liu)(liu)(liu)電(dian)(dian)通過(guo)(guo)變壓(ya)器降為(wei)合適交(jiao)流(liu)(liu)(liu)電(dian)(dian)壓(ya)值，然后經過(guo)(guo)整流(liu)(liu)(liu)電(dian)(dian)路將交(jiao)流(liu)(liu)(liu)電(dian)(dian)轉(zhuan)為(wei)直(zhi)流(liu)(liu)(liu)電(dian)(dian)，再通過(guo)(guo)濾波電(dian)(dian)路濾除(chu)直(zhi)流(liu)(liu)(liu)電(dian)(dian)中的(de)(de)交(jiao)流(liu)(liu)(liu)成分，后通過(guo)(guo)集成穩壓(ya)器構成的(de)(de)穩壓(ya)電(dian)(dian)路轉(zhuan)化為(wei)穩定(ding)直(zhi)流(liu)(liu)(liu)電(dian)(dian)輸出。集成穩壓(ya)器具有體積(ji)小、重量輕、安裝(zhuang)和調試方便(bian)、可(ke)靠(kao)性和穩定(ding)性高(gao)等優(you)點(dian)。

      可(ke)調式穩壓器內部(bu)含(han)有過流、過熱保護電(dian)路(lu)，具有，性能優良、不易損壞、使用方便(bian)等優點。其(qi)電(dian)壓調整率和電(dian)流調整率均優于固定式集成穩壓構(gou)成的可(ke)調電(dian)壓穩壓電(dian)源。

【注意】

☆ 負載與UPS連接時，須(xu)先關閉負載，再接線，然后再逐個打開負載。

☆ 將UPS接到的帶有過(guo)電流保(bao)護(hu)裝(zhuang)置的插座上。

☆ 所用電源插座(zuo)應連(lian)接(jie)保(bao)護地端。

☆ 無論輸入電源線(xian)是否插(cha)入市電插(cha)座，UPS輸出(chu)都可能帶電，關(guan)(guan)閉UPS并(bing)不能保(bao)證機內部件不帶電。如果要使UPS無輸出(chu)，須先關(guan)(guan)掉開關(guan)(guan)，再(zai)取消市電供應。

☆ 需接電動(dong)機、顯示器、激光打印(yin)機等(deng)電感性負載時，因(yin)其運行啟動(dong)功(gong)(gong)(gong)率(lv)過大，選(xuan)擇(ze)UPS時，容量要(yao)以啟動(dong)功(gong)(gong)(gong)率(lv)來計算。啟動(dong)功(gong)(gong)(gong)率(lv)一般取額定功(gong)(gong)(gong)率(lv)的兩倍(bei)。

☆ 若接(jie)發電(dian)機，需按(an)以下步驟進行：

啟(qi)動發(fa)電(dian)機，待其運行穩定(ding)后(hou)(hou)將發(fa)電(dian)機的確輸出(chu)電(dian)源接到UPS，輸入端(此時要確定(ding)UPS為空(kong)載)，然后(hou)(hou)按(an)開機程序啟(qi)動UPS，UPS啟(qi)動后(hou)(hou)，再逐個連入負載(建(jian)議以UPS兩倍(bei)容(rong)量(liang)來(lai)選擇發(fa)電(dian)機容(rong)量(liang))。
