穩(wen)壓器工作原理

由于(yu)部分電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)中(zhong)含有線(xian)圈組(zu)件，在通電(dian)(dian)(dian)(dian)(dian)(dian)初期會產生阻(zu)礙電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)渦流(liu)，渦流(liu)的(de)產生既會削弱到電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)啟(qi)動時(shi)(shi)(shi)的(de)瞬時(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，導(dao)致啟(qi)動緩慢，又會加強斷(duan)路(lu)后(hou)產生的(de)瞬時(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，可能產生火花損壞(huai)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)。此時(shi)(shi)(shi)便(bian)需(xu)要一個穩壓(ya)(ya)器(qi)來(lai)保(bao)護電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)的(de)正常運行(xing)。穩壓(ya)(ya)器(qi)由調壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)、控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)、及伺服電(dian)(dian)(dian)(dian)(dian)(dian)機等組(zu)成，當輸入電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)或負載(zai)變化時(shi)(shi)(shi)，控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)進行(xing)取樣(yang)、比較、放大，然(ran)后(hou)驅動伺服電(dian)(dian)(dian)(dian)(dian)(dian)機轉動，使調壓(ya)(ya)器(qi)碳刷的(de)位置改變，通過自動調整線(xian)圈匝數(shu)比，從而保(bao)持輸出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)穩定。容量(liang)較大的(de)穩壓(ya)(ya)器(qi)，還采用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)補(bu)償的(de)原理(li)工作。

穩壓器的作用

穩壓器(qi)是(shi)一種能(neng)自動調整輸出(chu)電(dian)壓的供(gong)(gong)電(dian)電(dian)路或供(gong)(gong)電(dian)設(she)(she)備(bei)，其作用是(shi)將波(bo)動較(jiao)大和達不到電(dian)器(qi)設(she)(she)備(bei)要求的電(dian)源電(dian)壓穩定(ding)在它(ta)的設(she)(she)定(ding)值范圍內，使各種電(dian)路或電(dian)器(qi)設(she)(she)備(bei)能(neng)在額定(ding)工作電(dian)壓下正常(chang)工作。

最初(chu)的(de)電(dian)(dian)(dian)(dian)力穩壓(ya)(ya)器(qi)是(shi)(shi)靠繼(ji)電(dian)(dian)(dian)(dian)器(qi)的(de)跳動(dong)穩定電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)。當電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)壓(ya)(ya)出現波(bo)動(dong)時(shi)，電(dian)(dian)(dian)(dian)力穩壓(ya)(ya)器(qi)的(de)自動(dong)糾正電(dian)(dian)(dian)(dian)路(lu)啟動(dong)，使內(nei)部繼(ji)電(dian)(dian)(dian)(dian)器(qi)動(dong)作。迫(po)使輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)保持在設定值附(fu)近，這種電(dian)(dian)(dian)(dian)路(lu)優點(dian)是(shi)(shi)電(dian)(dian)(dian)(dian)路(lu)簡(jian)單(dan)，缺點(dian)是(shi)(shi)穩壓(ya)(ya)精度(du)不(bu)高(gao)并且每一(yi)次繼(ji)電(dian)(dian)(dian)(dian)器(qi)跳動(dong)換擋(dang)，都會使供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)發生(sheng)一(yi)次瞬時(shi)的(de)中斷并產(chan)生(sheng)火花(hua)干(gan)擾(rao)。

這對電(dian)腦設(she)備(bei)的讀寫工作(zuo)干(gan)擾很大，容易造(zao)成電(dian)腦出現錯誤信號，嚴重時(shi)還(huan)會使硬盤(pan)損壞(huai)。

高(gao)質量的小型(xing)穩(wen)壓(ya)(ya)器，大(da)多(duo)采用電機拖動碳刷的方法穩(wen)定電壓(ya)(ya)，這(zhe)種穩(wen)壓(ya)(ya)器對電器設備產生的干擾很小穩(wen)壓(ya)(ya)精度相對較(jiao)高(gao)。

安全事宜

⒈穩壓電(dian)源(yuan)在通(tong)電(dian)啟動時，請勿(wu)隨意拆開穩壓電(dian)源(yuan)或(huo)撥(bo)拉穩壓電(dian)源(yuan)輸入輸出連線，以(yi)防觸電(dian)或(huo)其它(ta)電(dian)氣安全事故。

⒉穩(wen)壓電源(yuan)輸入輸出(chu)連線一定要布置合理，防(fang)止踩(cai)踏(ta)磨破，造(zao)成漏電事故。

⒊穩壓(ya)電(dian)源一定要可靠接(jie)地(di)，因不接(jie)地(di)線運行而(er)造成的觸電(dian)或人體傷害，由用戶(hu)自(zi)行負(fu)責。

⒋穩壓電源的地(di)線不能接在暖(nuan)氣管道(dao)、供水管道(dao)、燃(ran)氣管道(dao)等公益設施(shi)上，以(yi)免侵(qin)犯(fan)第(di)三方(fang)權(quan)利或造成危害(hai)。

⒌應定(ding)期檢(jian)查穩壓電源的輸入(ru)和輸出(chu)連線，以免松(song)動或(huo)脫落(luo)，從而(er)影響穩壓電源的正常使(shi)用和用電安全。

⒍穩壓器(qi)的(de)(de)連接線(xian)的(de)(de)選配必須(xu)達到(dao)規定能承載足夠的(de)(de)電流容量的(de)(de)連接線(xian)。

⒎.穩壓器(qi)應輕(qing)拿輕(qing)放，在工作的時候避免(mian)劇烈振動；

⒏、保證穩壓(ya)(ya)器的碳刷彈簧有足夠的壓(ya)(ya)力，以(yi)免碳刷和線圈接觸面(mian)跳(tiao)火；

⒐、非專業人員請不要(yao)拆開穩壓電源(yuan)或對穩壓電源(yuan)進行維(wei)修(xiu)。
