UPS電源的主要功能與作用

一、穩壓作用

市電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)容易受(shou)電(dian)(dian)(dian)(dian)(dian)力(li)輸送線路的距離(li)和品質影響，離(li)變(bian)電(dian)(dian)(dian)(dian)(dian)所較近的用(yong)(yong)(yong)(yong)戶電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)較高(gao)，離(li)變(bian)電(dian)(dian)(dian)(dian)(dian)所較遠的用(yong)(yong)(yong)(yong)戶電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)則會偏低(di)較低(di)。電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)過高(gao)或過低(di)都(dou)會影響用(yong)(yong)(yong)(yong)戶儀(yi)器設備的使(shi)用(yong)(yong)(yong)(yong)質量(liang)和使(shi)用(yong)(yong)(yong)(yong)壽(shou)命，較嚴(yan)重時則會損壞設備，給用(yong)(yong)(yong)(yong)戶造成(cheng)重大損失。UPS電(dian)(dian)(dian)(dian)(dian)源系(xi)統(tong)的使(shi)用(yong)(yong)(yong)(yong)則可(ke)以(yi)為用(yong)(yong)(yong)(yong)戶設備提供穩定的電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源，保障設備的正常運行和延長使(shi)用(yong)(yong)(yong)(yong)壽(shou)命；

二、停電保護作用

市電(dian)電(dian)網瞬間停(ting)電(dian)時立即由UPS電(dian)源系(xi)統將UPS蓄電(dian)池直流(liu)電(dian)源轉(zhuan)換(huan)成交流(liu)電(dian)繼續(xu)為負載供電(dian)，避免因停(ting)電(dian)而帶來的不便和損(sun)失；

三、高低電壓保護作用

當(dang)市電(dian)電(dian)壓(ya)時高時低，UP電(dian)源(yuan)內的(de)穩壓(ya)器(AVR)使(shi)市電(dian)電(dian)壓(ya)保持(chi)在可使(shi)用的(de)安全范(fan)圍，確(que)保設備(bei)可以正常運(yun)行(xing)。當(dang)高低電(dian)壓(ya)超過可使(shi)用的(de)范(fan)時，UPS電(dian)源(yuan)系統則將啟動蓄電(dian)池(chi)供電(dian)，保障(zhang)設備(bei)的(de)持(chi)續運(yun)行(xing)；

四、諧波失真保護作用

電力(li)經由(you)輸配電線路傳(chuan)送至使(shi)用(yong)端時，電壓(ya)波形失真，基波電流發生變化產(chan)生諧(xie)波。諧(xie)波會影響設備(bei)的使(shi)用(yong)，通(tong)過(guo)UPS電源則(ze)能為設備(bei)提供(gong)穩定高(gao)品(pin)質(zhi)的電源，有效(xiao)提高(gao)設備(bei)的運行效(xiao)率(lv)和壽(shou)命；

五、系統穩壓功能

系(xi)統的(de)(de)穩壓功能是由(you)整流器完成的(de)(de)，整流器件(jian)采用可(ke)控硅或高頻開關整流器，本(ben)身具有(you)可(ke)根據市電(dian)的(de)(de)變(bian)化控制輸(shu)出幅(fu)度的(de)(de)功能，從而當(dang)外(wai)電(dian)發生變(bian)化時（該變(bian)化應滿足系(xi)統要求），輸(shu)出幅(fu)度基本(ben)不變(bian)的(de)(de)整流電(dian)壓；

六、凈化功能

凈化功能由儲能電(dian)(dian)(dian)池來(lai)完成(cheng)，由于整(zheng)流(liu)器(qi)(qi)對(dui)瞬時脈(mo)沖(chong)干擾不(bu)能消除，整(zheng)流(liu)后(hou)的(de)電(dian)(dian)(dian)壓仍(reng)存在(zai)脈(mo)沖(chong)干擾。儲能電(dian)(dian)(dian)池除具有存儲直流(liu)電(dian)(dian)(dian)能的(de)功能外，對(dui)整(zheng)流(liu)器(qi)(qi)來(lai)說就像(xiang)接了(le)一只大容(rong)量電(dian)(dian)(dian)容(rong)器(qi)(qi)，其(qi)等(deng)效電(dian)(dian)(dian)容(rong)量的(de)大小，與儲能電(dian)(dian)(dian)池容(rong)量大小成(cheng)正比。由于電(dian)(dian)(dian)容(rong)兩端的(de)電(dian)(dian)(dian)壓是不(bu)能突變的(de)，即利(li)用了(le)電(dian)(dian)(dian)容(rong)器(qi)(qi)對(dui)脈(mo)沖(chong)的(de)平滑特性消除了(le)脈(mo)沖(chong)干擾，起到了(le)凈化功能，也稱(cheng)對(dui)干擾的(de)屏(ping)蔽。
