穩壓器的原理

最初(chu)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力穩壓(ya)器是(shi)靠繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)跳動穩定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)出(chu)現波動時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力穩壓(ya)器的(de)自動糾(jiu)正電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路啟動，使內部繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器動作。迫使輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)保持在設定值附近，這種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路優點(dian)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路簡(jian)單，缺點(dian)是(shi)穩壓(ya)精度不高并且(qie)每一次(ci)繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器跳動換(huan)擋，都會使供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源發生一次(ci)瞬時(shi)的(de)中斷并產生火(huo)花干(gan)擾。

現在(zai)的(de)(de)(de)穩(wen)(wen)壓(ya)(ya)(ya)器(qi)(qi)工作(zuo)原理(li)比較(jiao)(jiao)簡(jian)單，它(ta)是由(you)調(diao)壓(ya)(ya)(ya)電(dian)(dian)路、控(kong)制電(dian)(dian)路、及(ji)伺服電(dian)(dian)機等部件組成，當(dang)輸入電(dian)(dian)壓(ya)(ya)(ya)或負(fu)載變化時，控(kong)制電(dian)(dian)路進行取樣、比較(jiao)(jiao)、放大，然后驅動伺服電(dian)(dian)機轉動，使調(diao)壓(ya)(ya)(ya)器(qi)(qi)碳刷的(de)(de)(de)位置改變，通(tong)過自動調(diao)整線圈匝數比，從而保持輸出電(dian)(dian)壓(ya)(ya)(ya)的(de)(de)(de)穩(wen)(wen)定。容(rong)量較(jiao)(jiao)大的(de)(de)(de)穩(wen)(wen)壓(ya)(ya)(ya)器(qi)(qi)，還(huan)采(cai)用(yong)電(dian)(dian)壓(ya)(ya)(ya)補償(chang)的(de)(de)(de)原理(li)工作(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(da)多采用電(dian)機拖動(dong)碳刷的方法穩定(ding)電(dian)壓，這種(zhong)穩壓器(qi)對電(dian)器(qi)設備產(chan)生的干擾很小穩壓精度相對較高(gao)。

穩壓器怎么使用

先(xian)把(ba)電器的(de)電源接在穩(wen)壓(ya)(ya)器上，然后再打開(kai)穩(wen)壓(ya)(ya)器的(de)電源開(kai)關，檢測(ce)是否可以正常(chang)使用(yong)，檢測(ce)完(wan)后就可以將大功(gong)率(lv)負載接在穩(wen)壓(ya)(ya)器上了(le)。注意，當電器長(chang)時間不用(yong)時，要(yao)把(ba)穩(wen)壓(ya)(ya)器的(de)電源切斷(duan)，這(zhe)樣才(cai)能延長(chang)穩(wen)壓(ya)(ya)器的(de)使用(yong)壽(shou)命。

穩壓器的保養方法

1、穩壓器的(de)功(gong)率(lv)應(ying)大(da)于(yu)用(yong)(yong)電(dian)設備(bei)的(de)總功(gong)率(lv)，使用(yong)(yong)時，應(ying)放(fang)置(zhi)在通風、干(gan)燥、無陽光直射、無腐蝕性(xing)氣體(ti)的(de)室(shi)內使用(yong)(yong)。

2、經常(chang)觀(guan)察穩壓器(qi)的冷(leng)卻風扇(shan)和傳動(dong)機構是否(fou)運行正常(chang)，查看輸入(ru)電壓和負載是否(fou)超過額定范圍，發現(xian)異常(chang)及時處理(li)。

3、穩壓(ya)(ya)器(qi)開(kai)關(guan)(guan)不(bu)宜作(zuo)設備的總開(kai)關(guan)(guan)使(shi)用(yong)，使(shi)用(yong)時，應先(xian)打開(kai)穩壓(ya)(ya)器(qi)開(kai)關(guan)(guan)，待有電(dian)源輸出后(hou)，再依(yi)次從(cong)按功率小到大接上(shang)(shang)不(bu)同的用(yong)電(dian)設備，關(guan)(guan)機時從(cong)大到小關(guan)(guan)機，最后(hou)關(guan)(guan)上(shang)(shang)穩壓(ya)(ya)器(qi)的開(kai)關(guan)(guan)。
