【穩壓器(qi)(qi)的(de)作用(yong)】穩壓器(qi)(qi)的(de)用(yong)途 穩壓器的功能(neng) 穩壓器(qi)有什么用？

穩壓器的(de)用途就是起到(dao)穩定(ding)電(dian)(dian)壓的(de)作(zuo)用，電(dian)(dian)壓高了，它降(jiang)下來，電(dian)(dian)壓低了 ，再升上去。

穩(wen)壓器主要由調壓電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)、控(kong)制電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)、及伺服電(dian)(dian)(dian)(dian)(dian)機(ji)等(deng)組成，當輸入電(dian)(dian)(dian)(dian)(dian)壓或負載變化時，控(kong)制電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)進行取樣(yang)、比較、放大(da)，然后驅動伺服電(dian)(dian)(dian)(dian)(dian)機(ji)轉動，使(shi)調壓器碳刷的(de)(de)位(wei)置改變，通過自動調整線(xian)圈匝數比，從而保持輸出電(dian)(dian)(dian)(dian)(dian)壓的(de)(de)穩(wen)定(ding)。容量較大(da)的(de)(de)穩(wen)壓器，還采用電(dian)(dian)(dian)(dian)(dian)壓補償(chang)的(de)(de)原理工作。

最初(chu)的(de)電(dian)(dian)(dian)力穩(wen)(wen)壓(ya)(ya)器(qi)是靠繼電(dian)(dian)(dian)器(qi)的(de)跳動(dong)穩(wen)(wen)定(ding)電(dian)(dian)(dian)壓(ya)(ya)的(de)。當電(dian)(dian)(dian)網電(dian)(dian)(dian)壓(ya)(ya)出現波動(dong)時(shi)，電(dian)(dian)(dian)力穩(wen)(wen)壓(ya)(ya)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。迫使輸出電(dian)(dian)(dian)壓(ya)(ya)保(bao)持(chi)在設定(ding)值附近，這種(zhong)電(dian)(dian)(dian)路優點(dian)是電(dian)(dian)(dian)路簡單，缺點(dian)是穩(wen)(wen)壓(ya)(ya)精度不(bu)高并且每(mei)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)源發生一次瞬時(shi)的(de)中斷并產生火花干擾。

后期(qi)也是現在(zai)的穩(wen)壓(ya)器一般是工業級穩(wen)壓(ya)器，工業級穩(wen)壓(ya)器是利(li)用感(gan)應(ying)原理來做電(dian)(dian)壓(ya)調整、無接(jie)點于負載(zai)中呈線性升降壓(ya)調整，電(dian)(dian)壓(ya)調整中，不(bu)會產(chan)生(sheng)頻率偏移及(ji)電(dian)(dian)涌(yong)，致(zhi)負載(zai)電(dian)(dian)力品質與輸入端相同。采用高效率和寬大(da)的安全范(fan)圍(wei)工業級零件組合而成，可以承(cheng)受惡(e)劣的溫度(du)、濕度(du)、震動(dong)及(ji)污穢環境。

隨著社會飛速發展(zhan)，用(yong)電(dian)(dian)(dian)設(she)備(bei)(bei)與日俱增。但電(dian)(dian)(dian)力輸配設(she)施的(de)老化和(he)發展(zhan)滯(zhi)后，以及設(she)計不良(liang)和(he)供(gong)電(dian)(dian)(dian)不足(zu)等原因造(zao)成未端(duan)用(yong)戶電(dian)(dian)(dian)壓(ya)的(de)過低，而線頭(tou)用(yong)戶則(ze)經常電(dian)(dian)(dian)壓(ya)偏(pian)高，對用(yong)電(dian)(dian)(dian)設(she)備(bei)(bei)特別是(shi)對電(dian)(dian)(dian)壓(ya)要求嚴格的(de)高新(xin)科技和(he)精密設(she)備(bei)(bei)，猶如一顆不定(ding)時炸彈。

說到穩壓(ya)器(qi)的(de)(de)作(zuo)用(yong)，市電(dian)系(xi)統(tong)作(zuo)為公共電(dian)網，上面連接了成(cheng)千上萬各(ge)式各(ge)樣的(de)(de)負載，其(qi)中(zhong)一(yi)些較大(da)的(de)(de)感(gan)性、容性、開關(guan)電(dian)源等負載不(bu)僅從(cong)電(dian)網中(zhong)獲得電(dian)能，還會反過來(lai)對(dui)電(dian)網本(ben)身造成(cheng)影(ying)(ying)響(xiang)，惡化電(dian)網或局部電(dian)網的(de)(de)供(gong)電(dian)品質，造成(cheng)市電(dian)電(dian)壓(ya)波形(xing)畸變(bian)或頻(pin)率漂移。另(ling)外(wai)意(yi)外(wai)的(de)(de)自然和人(ren)為事故，如地震、雷擊、輸變(bian)電(dian)系(xi)統(tong)斷路或短路，都會危害電(dian)力的(de)(de)正(zheng)常供(gong)應，從(cong)而影(ying)(ying)響(xiang)負載的(de)(de)正(zheng)常工作(zuo)。

不穩定的電壓會使(shi)設(she)備(bei)造(zao)(zao)成致(zhi)命傷害或誤動作，影(ying)響生(sheng)產，造(zao)(zao)成交貨期延(yan)誤、品質不穩定等(deng)多(duo)方面(mian)損(sun)失。同(tong)時加速設(she)備(bei)的老化、影(ying)響使(shi)用壽(shou)命甚(shen)至燒毀配件，使(shi)業主面(mian)臨需要維修的困擾或短期內就要更(geng)新(xin)設(she)備(bei)，浪費資源；嚴重(zhong)者甚(shen)至發生(sheng)安全事故，造(zao)(zao)成不可(ke)估量的損(sun)失。

穩(wen)壓器對于(yu)用電設備(bei)特別(bie)是對電壓要求嚴(yan)格(ge)的(de)高新科技和精密設備(bei)來說(shuo)是必不(bu)可少(shao)的(de)。
