穩壓器的原理
最(zui)初的(de)電(dian)(dian)(dian)(dian)力(li)穩壓(ya)器是(shi)靠繼電(dian)(dian)(dian)(dian)器的(de)跳(tiao)(tiao)動(dong)(dong)穩定電(dian)(dian)(dian)(dian)壓(ya)的(de)，當電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)壓(ya)出現(xian)波動(dong)(dong)時，電(dian)(dian)(dian)(dian)力(li)穩壓(ya)器的(de)自動(dong)(dong)糾正電(dian)(dian)(dian)(dian)路啟動(dong)(dong)，使(shi)內部繼電(dian)(dian)(dian)(dian)器動(dong)(dong)作。迫使(shi)輸出電(dian)(dian)(dian)(dian)壓(ya)保持在設定值附近，這種(zhong)電(dian)(dian)(dian)(dian)路優點是(shi)電(dian)(dian)(dian)(dian)路簡單，缺點是(shi)穩壓(ya)精度不高并且每一(yi)次繼電(dian)(dian)(dian)(dian)器跳(tiao)(tiao)動(dong)(dong)換擋，都會使(shi)供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源發生一(yi)次瞬(shun)時的(de)中斷并產(chan)生火花干(gan)擾。
現在的穩(wen)壓(ya)(ya)器(qi)工(gong)作原理比(bi)較(jiao)簡單，它是由調(diao)壓(ya)(ya)電(dian)(dian)(dian)路(lu)、控制(zhi)電(dian)(dian)(dian)路(lu)、及(ji)伺服電(dian)(dian)(dian)機(ji)等(deng)部件組(zu)成(cheng)，當輸入電(dian)(dian)(dian)壓(ya)(ya)或(huo)負(fu)載變化時(shi)，控制(zhi)電(dian)(dian)(dian)路(lu)進行(xing)取樣、比(bi)較(jiao)、放大，然后驅動伺服電(dian)(dian)(dian)機(ji)轉動，使調(diao)壓(ya)(ya)器(qi)碳(tan)刷(shua)的位(wei)置改變，通過自動調(diao)整線圈匝數比(bi)，從而保持輸出電(dian)(dian)(dian)壓(ya)(ya)的穩(wen)定。容量(liang)較(jiao)大的穩(wen)壓(ya)(ya)器(qi)，還(huan)采用電(dian)(dian)(dian)壓(ya)(ya)補償的原理工(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(cai)用電機拖動碳刷的(de)(de)方法穩(wen)定電壓(ya)(ya)，這(zhe)種穩(wen)壓(ya)(ya)器(qi)對電器(qi)設(she)備產生的(de)(de)干擾很小穩(wen)壓(ya)(ya)精度相(xiang)對較(jiao)高。
穩壓器怎么使用
先把(ba)電(dian)器(qi)(qi)的(de)電(dian)源接在穩(wen)壓(ya)器(qi)(qi)上(shang)，然(ran)后再打開穩(wen)壓(ya)器(qi)(qi)的(de)電(dian)源開關，檢(jian)測是否可(ke)以正常使用，檢(jian)測完后就可(ke)以將大功率(lv)負(fu)載接在穩(wen)壓(ya)器(qi)(qi)上(shang)了(le)。注(zhu)意，當電(dian)器(qi)(qi)長時(shi)間不用時(shi)，要把(ba)穩(wen)壓(ya)器(qi)(qi)的(de)電(dian)源切斷(duan)，這樣才(cai)能延長穩(wen)壓(ya)器(qi)(qi)的(de)使用壽(shou)命。
穩壓器的保養方法
1、穩壓器的功率(lv)(lv)應大于用電設備(bei)的總功率(lv)(lv)，使(shi)(shi)用時(shi)，應放置在(zai)通(tong)風、干燥、無(wu)陽光直射、無(wu)腐蝕性氣體的室內(nei)使(shi)(shi)用。
2、經常觀察穩壓器的冷卻(que)風(feng)扇和(he)傳動(dong)機(ji)構是否運行正常，查看輸入(ru)電(dian)壓和(he)負載是否超過額定范圍，發現異常及時處(chu)理。
3、穩壓器(qi)(qi)開(kai)關(guan)(guan)(guan)不(bu)宜(yi)作(zuo)設備的(de)(de)(de)總(zong)開(kai)關(guan)(guan)(guan)使(shi)用，使(shi)用時，應先打開(kai)穩壓器(qi)(qi)開(kai)關(guan)(guan)(guan)，待有電(dian)源輸(shu)出后，再(zai)依(yi)次從按(an)功率(lv)小到大接上不(bu)同的(de)(de)(de)用電(dian)設備，關(guan)(guan)(guan)機(ji)時從大到小關(guan)(guan)(guan)機(ji)，最后關(guan)(guan)(guan)上穩壓器(qi)(qi)的(de)(de)(de)開(kai)關(guan)(guan)(guan)。
