穩壓器的原理

最初的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)力穩壓(ya)器(qi)(qi)是(shi)靠繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)跳動(dong)(dong)穩定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)，當電(dian)(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)出現波動(dong)(dong)時，電(dian)(dian)(dian)(dian)(dian)(dian)力穩壓(ya)器(qi)(qi)的(de)(de)(de)自動(dong)(dong)糾(jiu)正電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)啟動(dong)(dong)，使(shi)內(nei)部繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)動(dong)(dong)作(zuo)。迫使(shi)輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)保持在設(she)定(ding)值附近，這(zhe)種電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)優點(dian)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)簡(jian)單，缺點(dian)是(shi)穩壓(ya)精度不高并且每一(yi)次繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)跳動(dong)(dong)換擋，都會使(shi)供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源發生(sheng)一(yi)次瞬(shun)時的(de)(de)(de)中斷(duan)并產生(sheng)火花干擾(rao)。

現在(zai)的(de)(de)穩壓(ya)(ya)(ya)器工(gong)作原(yuan)理(li)比較簡(jian)單，它是由調壓(ya)(ya)(ya)電(dian)路、控制(zhi)電(dian)路、及伺(si)服電(dian)機等部件組成，當輸入電(dian)壓(ya)(ya)(ya)或負載變(bian)化時，控制(zhi)電(dian)路進(jin)行取(qu)樣(yang)、比較、放大，然(ran)后驅動伺(si)服電(dian)機轉動，使調壓(ya)(ya)(ya)器碳(tan)刷的(de)(de)位置改變(bian)，通過自動調整線圈(quan)匝數(shu)比，從而保持輸出電(dian)壓(ya)(ya)(ya)的(de)(de)穩定。容(rong)量(liang)較大的(de)(de)穩壓(ya)(ya)(ya)器，還采用電(dian)壓(ya)(ya)(ya)補償的(de)(de)原(yuan)理(li)工(gong)作。

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)(dian)機拖動碳刷的方法(fa)穩(wen)定(ding)電(dian)(dian)壓(ya)，這種穩(wen)壓(ya)器(qi)對(dui)(dui)電(dian)(dian)器(qi)設備產生的干擾(rao)很小穩(wen)壓(ya)精度相對(dui)(dui)較高(gao)。

穩壓器怎么使用

先把(ba)電器(qi)(qi)(qi)的電源(yuan)接在穩(wen)壓(ya)(ya)器(qi)(qi)(qi)上(shang)，然后(hou)再打開(kai)穩(wen)壓(ya)(ya)器(qi)(qi)(qi)的電源(yuan)開(kai)關，檢測是否可以(yi)正常使用(yong)，檢測完后(hou)就可以(yi)將大功率負(fu)載接在穩(wen)壓(ya)(ya)器(qi)(qi)(qi)上(shang)了。注意(yi)，當電器(qi)(qi)(qi)長時間不用(yong)時，要把(ba)穩(wen)壓(ya)(ya)器(qi)(qi)(qi)的電源(yuan)切斷，這(zhe)樣才能延長穩(wen)壓(ya)(ya)器(qi)(qi)(qi)的使用(yong)壽命。

穩壓器的保養方法

1、穩壓(ya)器的功率應(ying)大(da)于用電設備的總(zong)功率，使用時(shi)，應(ying)放置在通(tong)風、干燥、無陽光(guang)直射、無腐蝕(shi)性(xing)氣體(ti)的室內(nei)使用。

2、經常(chang)觀察(cha)穩壓器(qi)的冷卻風扇和傳(chuan)動機構是否(fou)運行(xing)正常(chang)，查(cha)看輸入電壓和負載是否(fou)超過額定(ding)范圍，發現異(yi)常(chang)及(ji)時處理(li)。

3、穩壓器開關(guan)不宜(yi)作設(she)備的總(zong)開關(guan)使用，使用時(shi)，應先打開穩壓器開關(guan)，待有電(dian)源輸出后，再依次從按功(gong)率小到大(da)接上不同的用電(dian)設(she)備，關(guan)機時(shi)從大(da)到小關(guan)機，最后關(guan)上穩壓器的開關(guan)。
