【穩(wen)壓器的作用】穩(wen)壓器的用途(tu) 穩壓器的功能 穩(wen)壓(ya)器有什么用(yong)？

穩壓器的用(yong)途就(jiu)是起到(dao)穩定電(dian)壓(ya)(ya)的作(zuo)用(yong)，電(dian)壓(ya)(ya)高了(le)(le)，它降(jiang)下(xia)來(lai)，電(dian)壓(ya)(ya)低了(le)(le) ，再升上去。

穩(wen)(wen)壓(ya)器(qi)主要由調(diao)壓(ya)電(dian)(dian)(dian)路(lu)、控(kong)制(zhi)電(dian)(dian)(dian)路(lu)、及伺(si)服電(dian)(dian)(dian)機(ji)等組成，當輸(shu)入電(dian)(dian)(dian)壓(ya)或負載(zai)變化時，控(kong)制(zhi)電(dian)(dian)(dian)路(lu)進行取(qu)樣、比(bi)較(jiao)、放大，然后(hou)驅動(dong)伺(si)服電(dian)(dian)(dian)機(ji)轉動(dong)，使調(diao)壓(ya)器(qi)碳(tan)刷的位置(zhi)改(gai)變，通過自(zi)動(dong)調(diao)整線圈(quan)匝數比(bi)，從(cong)而保持輸(shu)出電(dian)(dian)(dian)壓(ya)的穩(wen)(wen)定。容(rong)量較(jiao)大的穩(wen)(wen)壓(ya)器(qi)，還采用電(dian)(dian)(dian)壓(ya)補(bu)償的原理工(gong)作。

最(zui)初的電(dian)(dian)力(li)(li)穩壓(ya)器是靠(kao)繼電(dian)(dian)器的跳動穩定(ding)電(dian)(dian)壓(ya)的。當電(dian)(dian)網電(dian)(dian)壓(ya)出現波(bo)動時，電(dian)(dian)力(li)(li)穩壓(ya)器的自(zi)動糾正電(dian)(dian)路啟動，使內部(bu)繼電(dian)(dian)器動作。迫使輸出電(dian)(dian)壓(ya)保(bao)持在設定(ding)值附近，這種電(dian)(dian)路優點是電(dian)(dian)路簡(jian)單，缺點是穩壓(ya)精(jing)度不高并且每(mei)一(yi)(yi)次(ci)繼電(dian)(dian)器跳動換擋，都(dou)會(hui)使供(gong)電(dian)(dian)電(dian)(dian)源發生(sheng)一(yi)(yi)次(ci)瞬時的中(zhong)斷并產生(sheng)火花干擾。

后(hou)期也(ye)是現(xian)在的(de)(de)穩壓(ya)(ya)(ya)器(qi)一般是工業(ye)級(ji)穩壓(ya)(ya)(ya)器(qi)，工業(ye)級(ji)穩壓(ya)(ya)(ya)器(qi)是利用感(gan)應原理來做電壓(ya)(ya)(ya)調(diao)(diao)整、無(wu)接點于負(fu)載中(zhong)呈(cheng)線性升(sheng)降壓(ya)(ya)(ya)調(diao)(diao)整，電壓(ya)(ya)(ya)調(diao)(diao)整中(zhong)，不會產生頻率偏移及(ji)電涌，致負(fu)載電力品質與(yu)輸入端(duan)相同。采用高效率和(he)寬大的(de)(de)安全(quan)范圍(wei)工業(ye)級(ji)零件組(zu)合而成，可以承受(shou)惡劣的(de)(de)溫度、濕度、震動及(ji)污穢環境。

隨著(zhu)社(she)會飛速發(fa)展，用電(dian)設(she)備與(yu)日俱增(zeng)。但電(dian)力輸配(pei)設(she)施的(de)老化和發(fa)展滯后，以及設(she)計(ji)不良(liang)和供電(dian)不足(zu)等原因造成(cheng)未端(duan)用戶電(dian)壓(ya)的(de)過低，而線頭用戶則經常電(dian)壓(ya)偏高，對用電(dian)設(she)備特別是(shi)對電(dian)壓(ya)要求嚴(yan)格(ge)的(de)高新科(ke)技和精密(mi)設(she)備，猶如一(yi)顆不定時(shi)炸彈。

說到穩壓器的作(zuo)用，市電(dian)(dian)(dian)系統作(zuo)為公共電(dian)(dian)(dian)網(wang)(wang)，上(shang)面連接了(le)成千上(shang)萬各式各樣(yang)的負載，其中(zhong)一些(xie)較大的感性、容性、開關電(dian)(dian)(dian)源等負載不僅從電(dian)(dian)(dian)網(wang)(wang)中(zhong)獲得(de)電(dian)(dian)(dian)能，還會(hui)反過來對電(dian)(dian)(dian)網(wang)(wang)本身造成影響，惡化電(dian)(dian)(dian)網(wang)(wang)或(huo)局部電(dian)(dian)(dian)網(wang)(wang)的供(gong)電(dian)(dian)(dian)品質，造成市電(dian)(dian)(dian)電(dian)(dian)(dian)壓波形畸(ji)變或(huo)頻(pin)率漂移。另外意外的自然和人(ren)為事故，如地震、雷擊、輸變電(dian)(dian)(dian)系統斷(duan)路(lu)或(huo)短路(lu)，都會(hui)危(wei)害電(dian)(dian)(dian)力(li)的正常(chang)(chang)供(gong)應(ying)，從而影響負載的正常(chang)(chang)工作(zuo)。

不(bu)穩定(ding)的電(dian)壓(ya)會使設(she)備(bei)造成致命傷(shang)害(hai)或(huo)誤(wu)動(dong)作(zuo)，影響(xiang)生產，造成交貨期延誤(wu)、品質不(bu)穩定(ding)等多方(fang)面(mian)損(sun)失。同時加速設(she)備(bei)的老化、影響(xiang)使用壽命甚至燒毀配件，使業主面(mian)臨需(xu)要維修的困擾或(huo)短期內就要更新設(she)備(bei)，浪費(fei)資源；嚴重(zhong)者甚至發生安全事故，造成不(bu)可估量的損(sun)失。

穩壓(ya)器對于用電(dian)設備特別是(shi)對電(dian)壓(ya)要(yao)求嚴格的高新科技(ji)和(he)精密(mi)設備來說是(shi)必(bi)不可(ke)少(shao)的。
