穩壓器的原理

最初的電(dian)(dian)(dian)(dian)力穩(wen)(wen)壓(ya)器(qi)(qi)是靠繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)的跳(tiao)動(dong)(dong)(dong)(dong)穩(wen)(wen)定電(dian)(dian)(dian)(dian)壓(ya)的，當電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)壓(ya)出現波(bo)動(dong)(dong)(dong)(dong)時(shi)(shi)，電(dian)(dian)(dian)(dian)力穩(wen)(wen)壓(ya)器(qi)(qi)的自動(dong)(dong)(dong)(dong)糾正電(dian)(dian)(dian)(dian)路啟動(dong)(dong)(dong)(dong)，使內部繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)動(dong)(dong)(dong)(dong)作(zuo)。迫使輸出電(dian)(dian)(dian)(dian)壓(ya)保持在設定值附(fu)近，這種電(dian)(dian)(dian)(dian)路優(you)點是電(dian)(dian)(dian)(dian)路簡單，缺點是穩(wen)(wen)壓(ya)精度不高并且(qie)每一(yi)次繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)跳(tiao)動(dong)(dong)(dong)(dong)換擋，都(dou)會(hui)使供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源發(fa)生一(yi)次瞬時(shi)(shi)的中(zhong)斷并產生火花干擾(rao)。

現在的穩壓器(qi)(qi)工(gong)作(zuo)原(yuan)理(li)比(bi)較(jiao)簡單(dan)，它是(shi)由調壓電(dian)(dian)(dian)(dian)路、控制電(dian)(dian)(dian)(dian)路、及(ji)伺服電(dian)(dian)(dian)(dian)機等部件組(zu)成，當輸(shu)入電(dian)(dian)(dian)(dian)壓或(huo)負載變化(hua)時，控制電(dian)(dian)(dian)(dian)路進行取樣、比(bi)較(jiao)、放大(da)，然后驅動(dong)伺服電(dian)(dian)(dian)(dian)機轉動(dong)，使調壓器(qi)(qi)碳刷的位置改(gai)變，通過自動(dong)調整線(xian)圈匝數比(bi)，從而(er)保持輸(shu)出電(dian)(dian)(dian)(dian)壓的穩定(ding)。容量較(jiao)大(da)的穩壓器(qi)(qi)，還(huan)采用電(dian)(dian)(dian)(dian)壓補償(chang)的原(yuan)理(li)工(gong)作(zuo)。

穩壓器有什么用

穩壓器是一種能自動調整輸出電壓的供電電路或供電設備，其作用是將波動較大和達不到電器設備要求的電源電壓穩定在它的設定值范圍內，使各種電路或電器設備能在額定工作電壓下正常工作。高質量的穩壓器品牌產品，大多采用電機拖動碳刷的方法穩定電壓，這(zhe)種穩壓器對(dui)電器設備產生的干擾很小穩壓精度相對(dui)較高。

穩壓器怎么使用

先(xian)把電器(qi)的電源(yuan)接在穩(wen)壓器(qi)上，然(ran)后再打開穩(wen)壓器(qi)的電源(yuan)開關，檢(jian)測是否可以(yi)正常(chang)使(shi)用(yong)，檢(jian)測完后就可以(yi)將大(da)功率(lv)負載(zai)接在穩(wen)壓器(qi)上了。注(zhu)意，當(dang)電器(qi)長時(shi)間(jian)不用(yong)時(shi)，要(yao)把穩(wen)壓器(qi)的電源(yuan)切(qie)斷，這樣才能延長穩(wen)壓器(qi)的使(shi)用(yong)壽命。

穩壓器的保養方法

1、穩壓器的功率應(ying)大于用電設備的總功率，使用時，應(ying)放置在通(tong)風、干燥、無陽光直(zhi)射、無腐蝕(shi)性氣體的室內使用。

2、經常(chang)觀察穩(wen)壓器的冷卻風(feng)扇和(he)傳動機構(gou)是(shi)否運行(xing)正常(chang)，查看輸入(ru)電(dian)壓和(he)負載是(shi)否超(chao)過(guo)額定范圍，發現(xian)異常(chang)及(ji)時處理。

3、穩壓(ya)器(qi)開關(guan)(guan)不(bu)宜作設備的(de)(de)總開關(guan)(guan)使用，使用時，應先打開穩壓(ya)器(qi)開關(guan)(guan)，待(dai)有(you)電源輸出后(hou)，再依次(ci)從(cong)按功率小到大接(jie)上(shang)不(bu)同(tong)的(de)(de)用電設備，關(guan)(guan)機(ji)時從(cong)大到小關(guan)(guan)機(ji)，最后(hou)關(guan)(guan)上(shang)穩壓(ya)器(qi)的(de)(de)開關(guan)(guan)。
