【穩壓器的作用】穩壓器的用途 穩壓器的功能 穩壓器有什么用？

穩壓器的用途就是起到穩定電壓(ya)的作(zuo)用，電壓(ya)高了，它降下(xia)來(lai)，電壓(ya)低了 ，再(zai)升(sheng)上去(qu)。

穩(wen)壓(ya)器主要(yao)由調(diao)壓(ya)電(dian)路、控(kong)制(zhi)電(dian)路、及伺服電(dian)機(ji)等組成，當(dang)輸(shu)入(ru)電(dian)壓(ya)或(huo)負載變化時，控(kong)制(zhi)電(dian)路進行取樣、比較、放大，然后驅(qu)動(dong)伺服電(dian)機(ji)轉動(dong)，使調(diao)壓(ya)器碳刷的(de)位置改變，通(tong)過自動(dong)調(diao)整(zheng)線圈匝數比，從而(er)保持輸(shu)出(chu)電(dian)壓(ya)的(de)穩(wen)定。容量較大的(de)穩(wen)壓(ya)器，還采用電(dian)壓(ya)補(bu)償的(de)原(yuan)理工作。

最(zui)初的電(dian)(dian)(dian)力(li)穩壓(ya)器(qi)是靠繼電(dian)(dian)(dian)器(qi)的跳動(dong)穩定(ding)電(dian)(dian)(dian)壓(ya)的。當(dang)電(dian)(dian)(dian)網電(dian)(dian)(dian)壓(ya)出現(xian)波動(dong)時，電(dian)(dian)(dian)力(li)穩壓(ya)器(qi)的自(zi)動(dong)糾正電(dian)(dian)(dian)路(lu)啟動(dong)，使內部繼電(dian)(dian)(dian)器(qi)動(dong)作。迫(po)使輸(shu)出電(dian)(dian)(dian)壓(ya)保持(chi)在設定(ding)值附近，這(zhe)種電(dian)(dian)(dian)路(lu)優點(dian)是電(dian)(dian)(dian)路(lu)簡單，缺點(dian)是穩壓(ya)精(jing)度不(bu)高并(bing)且每一次繼電(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)一次瞬(shun)時的中斷并(bing)產生(sheng)火花干擾。

后期(qi)也是現在的穩壓(ya)器(qi)一般是工(gong)業(ye)級(ji)穩壓(ya)器(qi)，工(gong)業(ye)級(ji)穩壓(ya)器(qi)是利用感應原理(li)來做(zuo)電(dian)壓(ya)調整、無接(jie)點于負載中呈(cheng)線性升降壓(ya)調整，電(dian)壓(ya)調整中，不會產生頻率偏移及電(dian)涌，致負載電(dian)力品質與輸(shu)入端(duan)相同。采用高效率和寬大的安全(quan)范圍工(gong)業(ye)級(ji)零件(jian)組合(he)而成，可以承受(shou)惡劣的溫度、濕度、震(zhen)動(dong)及污穢環(huan)境。

隨著社會飛速發展(zhan)，用(yong)(yong)電設備與日俱增。但(dan)電力輸(shu)配設施的老化和發展(zhan)滯后，以及(ji)設計不(bu)良(liang)和供電不(bu)足等原因造成(cheng)未端用(yong)(yong)戶電壓的過低，而線(xian)頭(tou)用(yong)(yong)戶則經常電壓偏高(gao)，對用(yong)(yong)電設備特別是對電壓要求嚴格的高(gao)新科(ke)技(ji)和精密設備，猶如一(yi)顆(ke)不(bu)定時炸彈。

說(shuo)到穩(wen)壓(ya)器的(de)(de)(de)(de)作用(yong)，市(shi)電(dian)(dian)(dian)系(xi)統作為(wei)公共電(dian)(dian)(dian)網，上面(mian)連接了成(cheng)千上萬各式各樣(yang)的(de)(de)(de)(de)負(fu)載(zai)，其中(zhong)(zhong)一些較(jiao)大(da)的(de)(de)(de)(de)感性(xing)、容性(xing)、開(kai)關電(dian)(dian)(dian)源等負(fu)載(zai)不僅從(cong)電(dian)(dian)(dian)網中(zhong)(zhong)獲得(de)電(dian)(dian)(dian)能，還會反(fan)過來對(dui)電(dian)(dian)(dian)網本身造成(cheng)影響，惡(e)化電(dian)(dian)(dian)網或局部電(dian)(dian)(dian)網的(de)(de)(de)(de)供(gong)電(dian)(dian)(dian)品(pin)質，造成(cheng)市(shi)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)波(bo)形畸變(bian)或頻率(lv)漂移。另外意(yi)外的(de)(de)(de)(de)自然(ran)和人為(wei)事故(gu)，如地震、雷擊、輸變(bian)電(dian)(dian)(dian)系(xi)統斷路或短(duan)路，都會危害(hai)電(dian)(dian)(dian)力(li)的(de)(de)(de)(de)正常供(gong)應，從(cong)而影響負(fu)載(zai)的(de)(de)(de)(de)正常工作。

不穩定的(de)電壓會使(shi)設備造(zao)成致命傷(shang)害(hai)或(huo)誤(wu)動作，影響生產，造(zao)成交貨期(qi)延誤(wu)、品質不穩定等多方面損失。同時加速(su)設備的(de)老化、影響使(shi)用壽(shou)命甚至(zhi)燒(shao)毀配(pei)件，使(shi)業主面臨(lin)需(xu)要維修的(de)困(kun)擾(rao)或(huo)短(duan)期(qi)內就要更新設備，浪費資源；嚴(yan)重者甚至(zhi)發生安全事(shi)故，造(zao)成不可(ke)估(gu)量的(de)損失。

穩壓(ya)器對于用電(dian)設(she)備(bei)特別是對電(dian)壓(ya)要求嚴格的高新科技和精密(mi)設(she)備(bei)來說是必不(bu)可(ke)少(shao)的。
