穩壓(ya)器工作原理

由于(yu)部分(fen)電(dian)(dian)(dian)(dian)(dian)器(qi)中含有(you)線圈組件，在通(tong)電(dian)(dian)(dian)(dian)(dian)初期會(hui)產(chan)生(sheng)(sheng)阻礙電(dian)(dian)(dian)(dian)(dian)流的(de)(de)渦流，渦流的(de)(de)產(chan)生(sheng)(sheng)既(ji)會(hui)削弱到電(dian)(dian)(dian)(dian)(dian)器(qi)啟動(dong)(dong)時(shi)的(de)(de)瞬時(shi)電(dian)(dian)(dian)(dian)(dian)壓，導致啟動(dong)(dong)緩慢，又(you)會(hui)加(jia)強斷路(lu)后(hou)產(chan)生(sheng)(sheng)的(de)(de)瞬時(shi)電(dian)(dian)(dian)(dian)(dian)壓，可能產(chan)生(sheng)(sheng)火(huo)花損壞(huai)電(dian)(dian)(dian)(dian)(dian)路(lu)。此時(shi)便需要一個穩壓器(qi)來(lai)保護(hu)電(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)正(zheng)常(chang)運(yun)行(xing)(xing)。穩壓器(qi)由調壓電(dian)(dian)(dian)(dian)(dian)路(lu)、控制(zhi)電(dian)(dian)(dian)(dian)(dian)路(lu)、及伺服(fu)(fu)電(dian)(dian)(dian)(dian)(dian)機等(deng)組成(cheng)，當輸入電(dian)(dian)(dian)(dian)(dian)壓或負載變化時(shi)，控制(zhi)電(dian)(dian)(dian)(dian)(dian)路(lu)進行(xing)(xing)取樣、比較、放大，然后(hou)驅動(dong)(dong)伺服(fu)(fu)電(dian)(dian)(dian)(dian)(dian)機轉動(dong)(dong)，使(shi)調壓器(qi)碳刷的(de)(de)位置改(gai)變，通(tong)過自(zi)動(dong)(dong)調整線圈匝數比，從而保持輸出電(dian)(dian)(dian)(dian)(dian)壓的(de)(de)穩定(ding)。容(rong)量較大的(de)(de)穩壓器(qi)，還采(cai)用電(dian)(dian)(dian)(dian)(dian)壓補(bu)償的(de)(de)原理工作。

穩壓器的作用

穩(wen)壓(ya)器是一種能(neng)(neng)自(zi)動調整輸出電(dian)(dian)壓(ya)的供電(dian)(dian)電(dian)(dian)路(lu)或(huo)供電(dian)(dian)設(she)(she)備，其作(zuo)用是將波動較大和達不(bu)到電(dian)(dian)器設(she)(she)備要求(qiu)的電(dian)(dian)源電(dian)(dian)壓(ya)穩(wen)定(ding)在它的設(she)(she)定(ding)值范圍內(nei)，使各種電(dian)(dian)路(lu)或(huo)電(dian)(dian)器設(she)(she)備能(neng)(neng)在額定(ding)工作(zuo)電(dian)(dian)壓(ya)下正(zheng)常(chang)工作(zuo)。

最(zui)初的(de)(de)(de)電(dian)力(li)穩(wen)壓(ya)器是靠繼(ji)電(dian)器的(de)(de)(de)跳動(dong)(dong)穩(wen)定電(dian)壓(ya)的(de)(de)(de)。當電(dian)網電(dian)壓(ya)出現波動(dong)(dong)時(shi)，電(dian)力(li)穩(wen)壓(ya)器的(de)(de)(de)自動(dong)(dong)糾正電(dian)路啟動(dong)(dong)，使(shi)內部(bu)繼(ji)電(dian)器動(dong)(dong)作。迫使(shi)輸出電(dian)壓(ya)保(bao)持在設定值附(fu)近，這(zhe)種電(dian)路優點是電(dian)路簡(jian)單(dan)，缺(que)點是穩(wen)壓(ya)精度(du)不高并且每一(yi)次繼(ji)電(dian)器跳動(dong)(dong)換擋，都會使(shi)供電(dian)電(dian)源發生一(yi)次瞬時(shi)的(de)(de)(de)中(zhong)斷并產生火花干擾。

這對(dui)電(dian)腦設備的(de)讀寫工(gong)作干擾很(hen)大，容(rong)易造成(cheng)電(dian)腦出現錯誤信(xin)號，嚴(yan)重時還會(hui)使硬(ying)盤(pan)損壞。

高質量的(de)小型穩壓(ya)器(qi)，大多采用電(dian)(dian)(dian)機拖動碳刷(shua)的(de)方法(fa)穩定(ding)電(dian)(dian)(dian)壓(ya)，這種穩壓(ya)器(qi)對(dui)(dui)電(dian)(dian)(dian)器(qi)設備產生的(de)干(gan)擾(rao)很小穩壓(ya)精(jing)度相對(dui)(dui)較高。

安全事宜

⒈穩壓(ya)(ya)電(dian)源在通(tong)電(dian)啟動時，請(qing)勿隨意拆(chai)開穩壓(ya)(ya)電(dian)源或撥拉穩壓(ya)(ya)電(dian)源輸入輸出連線，以防觸電(dian)或其(qi)它(ta)電(dian)氣安全事故。

⒉穩壓電源輸入輸出連(lian)線一(yi)定要布(bu)置合理，防止踩踏磨破，造(zao)成漏電事(shi)故。

⒊穩壓(ya)電(dian)源一定要可靠接地，因不接地線運(yun)行而(er)造成(cheng)的(de)觸電(dian)或(huo)人體傷害(hai)，由用(yong)戶自行負責。

⒋穩壓電源的地線不(bu)能接在暖氣管道、供水管道、燃氣管道等公益(yi)設(she)施上，以免侵犯第(di)三方權利或造(zao)成(cheng)危害。

⒌應定期檢查穩壓(ya)電(dian)源的輸(shu)入(ru)和輸(shu)出連線，以免松動或脫落，從而影響穩壓(ya)電(dian)源的正常使用和用電(dian)安(an)全。

⒍穩壓器的(de)(de)連(lian)接線的(de)(de)選配必須(xu)達到規定能承載足夠的(de)(de)電流容量的(de)(de)連(lian)接線。

⒎.穩壓器應輕拿輕放，在工作的時候避免劇烈振動；

⒏、保證穩壓器的碳(tan)刷(shua)彈簧有足(zu)夠的壓力(li)，以免碳(tan)刷(shua)和線圈接觸面跳火(huo)；

⒐、非專(zhuan)業(ye)人員請(qing)不(bu)要拆開(kai)穩(wen)壓(ya)電(dian)源或對穩(wen)壓(ya)電(dian)源進行維修。
