穩壓器行業簡介

穩壓器的原理

最初的(de)(de)電(dian)(dian)(dian)力(li)穩壓器是(shi)靠繼電(dian)(dian)(dian)器的(de)(de)跳動(dong)(dong)穩定(ding)電(dian)(dian)(dian)壓的(de)(de)，當電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)壓出現波動(dong)(dong)時，電(dian)(dian)(dian)力(li)穩壓器的(de)(de)自動(dong)(dong)糾正電(dian)(dian)(dian)路啟動(dong)(dong)，使內部繼電(dian)(dian)(dian)器動(dong)(dong)作。迫使輸出電(dian)(dian)(dian)壓保持在(zai)設(she)定(ding)值附近，這種(zhong)電(dian)(dian)(dian)路優點是(shi)電(dian)(dian)(dian)路簡單，缺點是(shi)穩壓精度不高并且每一次繼電(dian)(dian)(dian)器跳動(dong)(dong)換擋，都會使供電(dian)(dian)(dian)電(dian)(dian)(dian)源發生一次瞬時的(de)(de)中(zhong)斷并產生火花(hua)干擾(rao)。

現在的(de)穩(wen)壓(ya)器工作原理(li)比較(jiao)簡單，它是由調壓(ya)電(dian)(dian)(dian)(dian)路(lu)、控(kong)制電(dian)(dian)(dian)(dian)路(lu)、及伺(si)服電(dian)(dian)(dian)(dian)機等部件組成，當輸入電(dian)(dian)(dian)(dian)壓(ya)或負(fu)載變化時，控(kong)制電(dian)(dian)(dian)(dian)路(lu)進行取樣、比較(jiao)、放大，然后(hou)驅動伺(si)服電(dian)(dian)(dian)(dian)機轉動，使(shi)調壓(ya)器碳刷的(de)位(wei)置改變，通過自動調整線(xian)圈匝數比，從而保持輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)的(de)穩(wen)定。容量較(jiao)大的(de)穩(wen)壓(ya)器，還采用電(dian)(dian)(dian)(dian)壓(ya)補償的(de)原理(li)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，大多采用電(dian)機拖(tuo)動碳刷的方法穩定電(dian)壓，這種穩壓器(qi)對(dui)電(dian)器(qi)設備產生的干(gan)擾很小穩壓精度相(xiang)對(dui)較高。

穩壓器怎么使用

先把電(dian)(dian)器(qi)(qi)的電(dian)(dian)源接(jie)在(zai)穩(wen)(wen)壓(ya)(ya)器(qi)(qi)上(shang)，然后再打(da)開穩(wen)(wen)壓(ya)(ya)器(qi)(qi)的電(dian)(dian)源開關，檢測是(shi)否可(ke)(ke)以正(zheng)常使(shi)用，檢測完(wan)后就可(ke)(ke)以將大功率負載接(jie)在(zai)穩(wen)(wen)壓(ya)(ya)器(qi)(qi)上(shang)了(le)。注意，當電(dian)(dian)器(qi)(qi)長時(shi)間不用時(shi)，要把穩(wen)(wen)壓(ya)(ya)器(qi)(qi)的電(dian)(dian)源切斷，這樣才(cai)能延長穩(wen)(wen)壓(ya)(ya)器(qi)(qi)的使(shi)用壽命。

穩壓器的保養方法

1、穩壓(ya)器的功(gong)率(lv)應(ying)大于用(yong)(yong)電設備的總功(gong)率(lv)，使用(yong)(yong)時，應(ying)放置在通風、干(gan)燥、無陽(yang)光直射、無腐蝕(shi)性(xing)氣體(ti)的室內使用(yong)(yong)。

2、經(jing)常觀察穩壓器的冷(leng)卻風扇和傳動(dong)機構(gou)是否運行正(zheng)常，查(cha)看輸入電壓和負載是否超過額定范圍，發現異常及時(shi)處理。

3、穩壓器開關(guan)不(bu)(bu)宜作設備的(de)總(zong)開關(guan)使用，使用時(shi)，應(ying)先打開穩壓器開關(guan)，待有電源輸出后(hou)，再(zai)依次從按功率(lv)小到(dao)大(da)接上(shang)不(bu)(bu)同的(de)用電設備，關(guan)機時(shi)從大(da)到(dao)小關(guan)機，最后(hou)關(guan)上(shang)穩壓器的(de)開關(guan)。
