穩壓器的原理

最初的(de)電(dian)(dian)(dian)(dian)(dian)(dian)力穩(wen)(wen)壓(ya)器是靠繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器的(de)跳動(dong)(dong)(dong)穩(wen)(wen)定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)，當電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)出(chu)現波動(dong)(dong)(dong)時，電(dian)(dian)(dian)(dian)(dian)(dian)力穩(wen)(wen)壓(ya)器的(de)自動(dong)(dong)(dong)糾正電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)啟動(dong)(dong)(dong)，使(shi)內部繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器動(dong)(dong)(dong)作。迫使(shi)輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)保(bao)持(chi)在設(she)定(ding)值(zhi)附近，這種電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)優點是電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)簡單，缺點是穩(wen)(wen)壓(ya)精度(du)不高(gao)并(bing)且每一次繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器跳動(dong)(dong)(dong)換擋，都會使(shi)供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)發(fa)生一次瞬時的(de)中斷并(bing)產生火花(hua)干擾(rao)。

現(xian)在的穩(wen)壓(ya)器(qi)工作原理比較(jiao)簡單(dan)，它是由調(diao)壓(ya)電(dian)路(lu)(lu)、控制電(dian)路(lu)(lu)、及伺服電(dian)機等部件組(zu)成，當輸(shu)入電(dian)壓(ya)或(huo)負載(zai)變化時，控制電(dian)路(lu)(lu)進(jin)行取樣、比較(jiao)、放大(da)(da)，然(ran)后驅(qu)動伺服電(dian)機轉動，使調(diao)壓(ya)器(qi)碳刷的位(wei)置改變，通過自動調(diao)整線圈匝數比，從(cong)而保持輸(shu)出電(dian)壓(ya)的穩(wen)定。容量較(jiao)大(da)(da)的穩(wen)壓(ya)器(qi)，還(huan)采(cai)用(yong)電(dian)壓(ya)補償的原理工作。

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，大多采(cai)用電(dian)機拖動(dong)碳刷的(de)方法(fa)穩定電(dian)壓，這(zhe)種穩壓器(qi)對電(dian)器(qi)設(she)備產生的(de)干擾很小穩壓精度相對較高。

穩壓器怎么使用

先把電器(qi)的(de)(de)電源接在穩(wen)壓器(qi)上，然后(hou)再打開穩(wen)壓器(qi)的(de)(de)電源開關，檢測是否(fou)可以正(zheng)常使用，檢測完后(hou)就可以將大功率負載接在穩(wen)壓器(qi)上了。注意，當(dang)電器(qi)長時間不用時，要(yao)把穩(wen)壓器(qi)的(de)(de)電源切斷，這樣才能延長穩(wen)壓器(qi)的(de)(de)使用壽命。

穩壓器的保養方法

1、穩壓器的(de)功率應(ying)大于用電(dian)設備的(de)總功率，使(shi)用時，應(ying)放(fang)置(zhi)在通風、干燥、無陽光直射、無腐蝕性(xing)氣體的(de)室(shi)內使(shi)用。

2、經常(chang)觀(guan)察穩壓器(qi)的冷卻風扇和(he)傳動(dong)機構是否運行正常(chang)，查(cha)看輸入電壓和(he)負載(zai)是否超過(guo)額定范圍，發現異常(chang)及時處理。

3、穩(wen)壓(ya)(ya)器(qi)開關(guan)(guan)(guan)不(bu)宜(yi)作設備(bei)的(de)總開關(guan)(guan)(guan)使用(yong)，使用(yong)時(shi)，應先打(da)開穩(wen)壓(ya)(ya)器(qi)開關(guan)(guan)(guan)，待有電源輸出(chu)后，再依次從按功率小(xiao)到大接上不(bu)同的(de)用(yong)電設備(bei)，關(guan)(guan)(guan)機時(shi)從大到小(xiao)關(guan)(guan)(guan)機，最后關(guan)(guan)(guan)上穩(wen)壓(ya)(ya)器(qi)的(de)開關(guan)(guan)(guan)。
