UPS電源的主要功能與作用

一、穩壓作用

 市電(dian)電(dian)壓容(rong)易受電(dian)力輸(shu)送(song)線路(lu)的(de)(de)距離(li)和(he)品質影響(xiang)，離(li)變(bian)電(dian)所較(jiao)(jiao)近的(de)(de)用(yong)(yong)(yong)(yong)戶(hu)電(dian)壓較(jiao)(jiao)高，離(li)變(bian)電(dian)所較(jiao)(jiao)遠的(de)(de)用(yong)(yong)(yong)(yong)戶(hu)電(dian)壓則會(hui)(hui)偏低(di)較(jiao)(jiao)低(di)。電(dian)壓過高或過低(di)都會(hui)(hui)影響(xiang)用(yong)(yong)(yong)(yong)戶(hu)儀器設(she)(she)備(bei)(bei)的(de)(de)使用(yong)(yong)(yong)(yong)質量和(he)使用(yong)(yong)(yong)(yong)壽命，較(jiao)(jiao)嚴(yan)重(zhong)時則會(hui)(hui)損(sun)壞設(she)(she)備(bei)(bei)，給用(yong)(yong)(yong)(yong)戶(hu)造成重(zhong)大損(sun)失(shi)。UPS電(dian)源系(xi)統的(de)(de)使用(yong)(yong)(yong)(yong)則可以為用(yong)(yong)(yong)(yong)戶(hu)設(she)(she)備(bei)(bei)提供(gong)穩定(ding)的(de)(de)電(dian)壓電(dian)源，保障設(she)(she)備(bei)(bei)的(de)(de)正常運(yun)行(xing)和(he)延長使用(yong)(yong)(yong)(yong)壽命；

二、停電保護作用

市電(dian)(dian)電(dian)(dian)網瞬間(jian)停(ting)電(dian)(dian)時立即由UPS電(dian)(dian)源系統將UPS蓄電(dian)(dian)池直流電(dian)(dian)源轉(zhuan)換成(cheng)交(jiao)流電(dian)(dian)繼續(xu)為負載供(gong)電(dian)(dian)，避免(mian)因停(ting)電(dian)(dian)而帶來的不(bu)便和損(sun)失；

三、高低電壓保護作用

當市(shi)電(dian)電(dian)壓(ya)時高(gao)時低(di)(di)，UP電(dian)源內(nei)的(de)穩壓(ya)器(AVR)使(shi)市(shi)電(dian)電(dian)壓(ya)保持在可使(shi)用的(de)安全范圍，確保設(she)(she)備(bei)可以正常運(yun)行。當高(gao)低(di)(di)電(dian)壓(ya)超過可使(shi)用的(de)范時，UPS電(dian)源系統則將啟動蓄電(dian)池供電(dian)，保障設(she)(she)備(bei)的(de)持續運(yun)行；

四、諧波失真保護作用

電(dian)(dian)力經由輸配電(dian)(dian)線路(lu)傳(chuan)送至使用(yong)端時，電(dian)(dian)壓波形失真，基波電(dian)(dian)流發(fa)生變(bian)化產生諧波。諧波會影響設備(bei)的使用(yong)，通過UPS電(dian)(dian)源則能為設備(bei)提供穩定(ding)高品質的電(dian)(dian)源，有效(xiao)提高設備(bei)的運行效(xiao)率(lv)和壽命；

五、系統穩壓功能

 系統(tong)的穩壓(ya)功能(neng)是由整(zheng)流器(qi)(qi)完(wan)成的，整(zheng)流器(qi)(qi)件采用可控硅或高頻開關整(zheng)流器(qi)(qi)，本身(shen)具有(you)可根據(ju)市電(dian)的變(bian)化控制輸(shu)出(chu)幅度(du)的功能(neng)，從而(er)當外電(dian)發(fa)生變(bian)化時(shi)（該(gai)變(bian)化應滿足系統(tong)要求），輸(shu)出(chu)幅度(du)基(ji)本不變(bian)的整(zheng)流電(dian)壓(ya)；

六、凈化功能

凈(jing)化(hua)功能(neng)(neng)由(you)儲能(neng)(neng)電(dian)(dian)池來完(wan)成，由(you)于(yu)整流器(qi)對瞬時(shi)脈(mo)沖干(gan)擾不(bu)能(neng)(neng)消(xiao)除(chu)，整流后(hou)的(de)電(dian)(dian)壓(ya)仍存在脈(mo)沖干(gan)擾。儲能(neng)(neng)電(dian)(dian)池除(chu)具有存儲直流電(dian)(dian)能(neng)(neng)的(de)功能(neng)(neng)外，對整流器(qi)來說就像接了一(yi)只大容(rong)量(liang)電(dian)(dian)容(rong)器(qi)，其等效(xiao)電(dian)(dian)容(rong)量(liang)的(de)大小，與(yu)儲能(neng)(neng)電(dian)(dian)池容(rong)量(liang)大小成正比。由(you)于(yu)電(dian)(dian)容(rong)兩端的(de)電(dian)(dian)壓(ya)是不(bu)能(neng)(neng)突變(bian)的(de)，即利用了電(dian)(dian)容(rong)器(qi)對脈(mo)沖的(de)平滑特(te)性消(xiao)除(chu)了脈(mo)沖干(gan)擾，起到了凈(jing)化(hua)功能(neng)(neng)，也稱對干(gan)擾的(de)屏蔽。
