【穩壓(ya)器的作用(yong)】穩壓(ya)器的用(yong)途 穩壓器(qi)的功能 穩壓(ya)器(qi)有什么用？

穩壓器的用途就是起到穩定電(dian)壓(ya)的作用，電(dian)壓(ya)高(gao)了，它(ta)降下來，電(dian)壓(ya)低(di)了 ，再升上去(qu)。

穩(wen)壓(ya)(ya)器(qi)(qi)主(zhu)要由調壓(ya)(ya)電(dian)(dian)(dian)路、控(kong)制(zhi)電(dian)(dian)(dian)路、及伺服(fu)電(dian)(dian)(dian)機等組成，當輸入(ru)電(dian)(dian)(dian)壓(ya)(ya)或負載變化時(shi)，控(kong)制(zhi)電(dian)(dian)(dian)路進(jin)行(xing)取樣、比較、放(fang)大，然(ran)后驅動伺服(fu)電(dian)(dian)(dian)機轉動，使調壓(ya)(ya)器(qi)(qi)碳刷的(de)(de)(de)位(wei)置改變，通(tong)過(guo)自動調整線圈(quan)匝(za)數比，從而保(bao)持輸出(chu)電(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)穩(wen)定。容量(liang)較大的(de)(de)(de)穩(wen)壓(ya)(ya)器(qi)(qi)，還采用電(dian)(dian)(dian)壓(ya)(ya)補償的(de)(de)(de)原(yuan)理工作。

最初(chu)的電(dian)(dian)(dian)(dian)(dian)力穩(wen)壓(ya)(ya)器(qi)(qi)是(shi)靠(kao)繼電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的跳動(dong)穩(wen)定電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的。當(dang)電(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)出(chu)(chu)現波動(dong)時，電(dian)(dian)(dian)(dian)(dian)力穩(wen)壓(ya)(ya)器(qi)(qi)的自動(dong)糾(jiu)正電(dian)(dian)(dian)(dian)(dian)路啟動(dong)，使(shi)(shi)內部繼電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)動(dong)作(zuo)。迫使(shi)(shi)輸出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)保持在設定值附近(jin)，這種電(dian)(dian)(dian)(dian)(dian)路優點是(shi)電(dian)(dian)(dian)(dian)(dian)路簡(jian)單，缺點是(shi)穩(wen)壓(ya)(ya)精度不高并且每一次繼電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)跳動(dong)換擋(dang)，都會使(shi)(shi)供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源發生(sheng)一次瞬時的中斷并產生(sheng)火花干擾。

后期也是現在的穩(wen)壓(ya)器一般(ban)是工(gong)業(ye)級穩(wen)壓(ya)器，工(gong)業(ye)級穩(wen)壓(ya)器是利用(yong)(yong)感應原理來做電(dian)壓(ya)調整(zheng)、無接點于負(fu)載中(zhong)呈線性升降壓(ya)調整(zheng)，電(dian)壓(ya)調整(zheng)中(zhong)，不(bu)會產生頻率(lv)偏移及電(dian)涌，致負(fu)載電(dian)力品(pin)質與輸入端(duan)相同(tong)。采用(yong)(yong)高效率(lv)和寬(kuan)大(da)的安全(quan)范圍工(gong)業(ye)級零(ling)件組合而成，可以承(cheng)受惡(e)劣的溫度(du)、濕度(du)、震動及污穢環境。

隨著社會飛(fei)速發展(zhan)，用(yong)(yong)電(dian)(dian)設備與日俱增。但電(dian)(dian)力(li)輸(shu)配設施的老化和發展(zhan)滯后(hou)，以及設計不良和供電(dian)(dian)不足(zu)等原因造成(cheng)未端用(yong)(yong)戶電(dian)(dian)壓(ya)的過低，而(er)線頭用(yong)(yong)戶則經常電(dian)(dian)壓(ya)偏高(gao)，對(dui)用(yong)(yong)電(dian)(dian)設備特別是(shi)對(dui)電(dian)(dian)壓(ya)要(yao)求(qiu)嚴格的高(gao)新科技和精(jing)密設備，猶如一顆不定時炸彈。

說到穩壓器的(de)(de)作(zuo)用，市(shi)電(dian)(dian)(dian)(dian)系(xi)統作(zuo)為(wei)公(gong)共電(dian)(dian)(dian)(dian)網，上面連接了成千上萬各式各樣的(de)(de)負載，其中一些較(jiao)大(da)的(de)(de)感(gan)性、容性、開關電(dian)(dian)(dian)(dian)源等負載不僅(jin)從(cong)電(dian)(dian)(dian)(dian)網中獲得(de)電(dian)(dian)(dian)(dian)能(neng)，還會反過(guo)來對電(dian)(dian)(dian)(dian)網本身造成影響，惡化(hua)電(dian)(dian)(dian)(dian)網或局部(bu)電(dian)(dian)(dian)(dian)網的(de)(de)供電(dian)(dian)(dian)(dian)品(pin)質，造成市(shi)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓波形(xing)畸(ji)變(bian)(bian)或頻率漂移(yi)。另外(wai)意外(wai)的(de)(de)自然和人(ren)為(wei)事故，如地(di)震(zhen)、雷擊(ji)、輸變(bian)(bian)電(dian)(dian)(dian)(dian)系(xi)統斷路或短(duan)路，都會危害(hai)電(dian)(dian)(dian)(dian)力的(de)(de)正(zheng)常(chang)(chang)供應，從(cong)而影響負載的(de)(de)正(zheng)常(chang)(chang)工作(zuo)。

不穩定(ding)的(de)電壓(ya)會使設備(bei)造(zao)成(cheng)致命傷(shang)害(hai)或誤動作(zuo)，影響生產，造(zao)成(cheng)交貨期延誤、品(pin)質不穩定(ding)等(deng)多方面(mian)損失(shi)。同(tong)時(shi)加速設備(bei)的(de)老化、影響使用(yong)壽命甚(shen)至(zhi)燒毀配件，使業主面(mian)臨需(xu)要維修的(de)困擾或短期內就要更新設備(bei)，浪(lang)費資源；嚴重者甚(shen)至(zhi)發生安全事故，造(zao)成(cheng)不可估量的(de)損失(shi)。

穩壓(ya)(ya)器(qi)對于用電(dian)設備(bei)特別(bie)是(shi)對電(dian)壓(ya)(ya)要求(qiu)嚴(yan)格的(de)高新科技和精密設備(bei)來(lai)說是(shi)必不可少的(de)。
