【穩(wen)壓器的作(zuo)用】穩(wen)壓器的用途 穩(wen)壓(ya)器的功能 穩(wen)壓器(qi)有什(shen)么用?
穩壓器的(de)用途就是起到穩定電壓的(de)作用,電壓高了,它降下來,電壓低(di)了 ,再升上去。
穩(wen)壓(ya)(ya)器(qi)主要由(you)調(diao)壓(ya)(ya)電(dian)(dian)(dian)路、控制電(dian)(dian)(dian)路、及(ji)伺服(fu)電(dian)(dian)(dian)機(ji)等組成,當輸入電(dian)(dian)(dian)壓(ya)(ya)或負(fu)載(zai)變(bian)化(hua)時,控制電(dian)(dian)(dian)路進行取樣、比(bi)(bi)較、放(fang)大,然后驅動(dong)(dong)伺服(fu)電(dian)(dian)(dian)機(ji)轉(zhuan)動(dong)(dong),使調(diao)壓(ya)(ya)器(qi)碳刷的(de)位置改變(bian),通過(guo)自動(dong)(dong)調(diao)整線圈(quan)匝數比(bi)(bi),從而保持輸出(chu)電(dian)(dian)(dian)壓(ya)(ya)的(de)穩(wen)定。容量較大的(de)穩(wen)壓(ya)(ya)器(qi),還采用電(dian)(dian)(dian)壓(ya)(ya)補償的(de)原(yuan)理工作(zuo)。
最初的(de)電(dian)(dian)(dian)力穩(wen)壓器(qi)是(shi)靠(kao)繼電(dian)(dian)(dian)器(qi)的(de)跳動(dong)穩(wen)定電(dian)(dian)(dian)壓的(de)。當(dang)電(dian)(dian)(dian)網電(dian)(dian)(dian)壓出現波動(dong)時,電(dian)(dian)(dian)力穩(wen)壓器(qi)的(de)自動(dong)糾正電(dian)(dian)(dian)路啟動(dong),使內部繼電(dian)(dian)(dian)器(qi)動(dong)作(zuo)。迫使輸出電(dian)(dian)(dian)壓保持在設定值附近,這種(zhong)電(dian)(dian)(dian)路優點(dian)是(shi)電(dian)(dian)(dian)路簡單,缺(que)點(dian)是(shi)穩(wen)壓精(jing)度(du)不高并且每一(yi)(yi)次繼電(dian)(dian)(dian)器(qi)跳動(dong)換(huan)擋,都會使供電(dian)(dian)(dian)電(dian)(dian)(dian)源發生(sheng)一(yi)(yi)次瞬時的(de)中斷并產生(sheng)火花干擾。
后期也是現在(zai)的(de)(de)穩壓(ya)(ya)器一般(ban)是工(gong)(gong)業級(ji)穩壓(ya)(ya)器,工(gong)(gong)業級(ji)穩壓(ya)(ya)器是利用感應(ying)原理(li)來做電(dian)(dian)壓(ya)(ya)調整、無接點于負載中呈線性升降(jiang)壓(ya)(ya)調整,電(dian)(dian)壓(ya)(ya)調整中,不會產生頻率偏移及電(dian)(dian)涌(yong),致(zhi)負載電(dian)(dian)力品(pin)質(zhi)與輸(shu)入(ru)端相同。采用高效(xiao)率和寬大的(de)(de)安全范圍工(gong)(gong)業級(ji)零件組合而成,可以承受惡(e)劣的(de)(de)溫度(du)、濕度(du)、震動(dong)及污(wu)穢環境(jing)。
隨(sui)著社(she)會飛速(su)發(fa)展(zhan),用電設(she)備(bei)與日俱(ju)增。但(dan)電力輸配設(she)施的(de)老化和發(fa)展(zhan)滯后,以及設(she)計不(bu)(bu)良和供電不(bu)(bu)足(zu)等原因(yin)造(zao)成未端用戶電壓(ya)(ya)的(de)過低(di),而(er)線頭用戶則(ze)經常電壓(ya)(ya)偏高(gao),對(dui)用電設(she)備(bei)特別是(shi)對(dui)電壓(ya)(ya)要求(qiu)嚴格的(de)高(gao)新(xin)科技和精密(mi)設(she)備(bei),猶如一(yi)顆不(bu)(bu)定時(shi)炸彈(dan)。
說(shuo)到穩壓(ya)器(qi)的(de)(de)作(zuo)(zuo)用,市電(dian)系統(tong)作(zuo)(zuo)為公共(gong)電(dian)網(wang),上面連接了成千上萬各式各樣的(de)(de)負(fu)(fu)載(zai)(zai),其中(zhong)一(yi)些較大的(de)(de)感性、容性、開關電(dian)源等負(fu)(fu)載(zai)(zai)不(bu)僅從電(dian)網(wang)中(zhong)獲得電(dian)能,還(huan)會反過(guo)來(lai)對(dui)電(dian)網(wang)本(ben)身造成影響,惡化電(dian)網(wang)或局部(bu)電(dian)網(wang)的(de)(de)供(gong)電(dian)品質,造成市電(dian)電(dian)壓(ya)波形畸變或頻率漂(piao)移(yi)。另外意外的(de)(de)自然和(he)人為事故(gu),如地震、雷擊、輸變電(dian)系統(tong)斷(duan)路或短路,都(dou)會危害電(dian)力的(de)(de)正常供(gong)應,從而影響負(fu)(fu)載(zai)(zai)的(de)(de)正常工作(zuo)(zuo)。
不穩(wen)(wen)定的(de)電壓會使(shi)設備(bei)造(zao)成致命傷害或誤動作,影(ying)響(xiang)生產,造(zao)成交貨期延(yan)誤、品質不穩(wen)(wen)定等多方(fang)面(mian)損失(shi)。同時加(jia)速(su)設備(bei)的(de)老化、影(ying)響(xiang)使(shi)用(yong)壽命甚(shen)至燒毀配件,使(shi)業主面(mian)臨(lin)需要維修的(de)困(kun)擾或短期內就(jiu)要更(geng)新設備(bei),浪費資源;嚴(yan)重者甚(shen)至發生安全事故,造(zao)成不可估量的(de)損失(shi)。
穩壓器對(dui)于用電設備特(te)別(bie)是對(dui)電壓要求嚴格的高新科技和精(jing)密設備來說是必不可少的。
