穩壓器工作原理

由于(yu)部分電(dian)(dian)(dian)(dian)器(qi)中(zhong)含(han)有(you)線圈(quan)組件，在通電(dian)(dian)(dian)(dian)初期會產(chan)生(sheng)(sheng)(sheng)阻(zu)礙電(dian)(dian)(dian)(dian)流的(de)(de)渦(wo)流，渦(wo)流的(de)(de)產(chan)生(sheng)(sheng)(sheng)既會削弱(ruo)到電(dian)(dian)(dian)(dian)器(qi)啟(qi)動(dong)(dong)(dong)時(shi)的(de)(de)瞬時(shi)電(dian)(dian)(dian)(dian)壓(ya)(ya)，導致啟(qi)動(dong)(dong)(dong)緩慢，又會加強(qiang)斷(duan)路后產(chan)生(sheng)(sheng)(sheng)的(de)(de)瞬時(shi)電(dian)(dian)(dian)(dian)壓(ya)(ya)，可(ke)能產(chan)生(sheng)(sheng)(sheng)火花損壞電(dian)(dian)(dian)(dian)路。此時(shi)便需要一個穩壓(ya)(ya)器(qi)來保(bao)護電(dian)(dian)(dian)(dian)路的(de)(de)正常運行(xing)。穩壓(ya)(ya)器(qi)由調(diao)壓(ya)(ya)電(dian)(dian)(dian)(dian)路、控制(zhi)電(dian)(dian)(dian)(dian)路、及伺服電(dian)(dian)(dian)(dian)機等組成，當(dang)輸(shu)入(ru)電(dian)(dian)(dian)(dian)壓(ya)(ya)或(huo)負載(zai)變化時(shi)，控制(zhi)電(dian)(dian)(dian)(dian)路進行(xing)取樣、比(bi)較、放大，然后驅動(dong)(dong)(dong)伺服電(dian)(dian)(dian)(dian)機轉(zhuan)動(dong)(dong)(dong)，使調(diao)壓(ya)(ya)器(qi)碳刷的(de)(de)位置(zhi)改變，通過自(zi)動(dong)(dong)(dong)調(diao)整線圈(quan)匝數比(bi)，從而保(bao)持(chi)輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)穩定(ding)。容量(liang)較大的(de)(de)穩壓(ya)(ya)器(qi)，還(huan)采用(yong)電(dian)(dian)(dian)(dian)壓(ya)(ya)補償(chang)的(de)(de)原理工作。

穩壓器的作用

穩(wen)壓器是一種能自動(dong)調整(zheng)輸出電(dian)壓的(de)(de)(de)供電(dian)電(dian)路(lu)或供電(dian)設備，其作(zuo)(zuo)用是將波動(dong)較大和達(da)不到電(dian)器設備要求的(de)(de)(de)電(dian)源電(dian)壓穩(wen)定在(zai)它的(de)(de)(de)設定值范圍內，使各(ge)種電(dian)路(lu)或電(dian)器設備能在(zai)額(e)定工作(zuo)(zuo)電(dian)壓下正(zheng)常工作(zuo)(zuo)。

最初的(de)電(dian)(dian)(dian)(dian)力穩(wen)壓(ya)(ya)器(qi)是靠繼(ji)電(dian)(dian)(dian)(dian)器(qi)的(de)跳(tiao)動穩(wen)定電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)。當電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)壓(ya)(ya)出(chu)現波動時，電(dian)(dian)(dian)(dian)力穩(wen)壓(ya)(ya)器(qi)的(de)自動糾正電(dian)(dian)(dian)(dian)路(lu)啟動，使內部繼(ji)電(dian)(dian)(dian)(dian)器(qi)動作。迫使輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)保持在設定值附近，這種電(dian)(dian)(dian)(dian)路(lu)優點是電(dian)(dian)(dian)(dian)路(lu)簡(jian)單(dan)，缺點是穩(wen)壓(ya)(ya)精(jing)度不高并(bing)且(qie)每(mei)一次繼(ji)電(dian)(dian)(dian)(dian)器(qi)跳(tiao)動換擋，都會使供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源發生一次瞬時的(de)中斷并(bing)產(chan)生火花干擾。

這對電腦(nao)設備的讀寫工作干擾很(hen)大，容易造成電腦(nao)出(chu)現錯誤信(xin)號(hao)，嚴重時還會(hui)使硬盤損壞。

高質(zhi)量的小型穩(wen)(wen)壓(ya)器(qi)，大多采用電(dian)機拖動碳刷的方法穩(wen)(wen)定電(dian)壓(ya)，這種穩(wen)(wen)壓(ya)器(qi)對電(dian)器(qi)設備產(chan)生的干擾(rao)很小穩(wen)(wen)壓(ya)精度相(xiang)對較高。

安全事宜

⒈穩(wen)(wen)壓(ya)(ya)電(dian)(dian)(dian)源在通電(dian)(dian)(dian)啟動時，請勿隨意拆開穩(wen)(wen)壓(ya)(ya)電(dian)(dian)(dian)源或(huo)(huo)撥拉穩(wen)(wen)壓(ya)(ya)電(dian)(dian)(dian)源輸入輸出連線，以防觸電(dian)(dian)(dian)或(huo)(huo)其它電(dian)(dian)(dian)氣(qi)安全事故。

⒉穩(wen)壓電(dian)源輸入輸出連線一(yi)定要布置(zhi)合理，防止(zhi)踩踏磨破，造(zao)成漏電(dian)事故。

⒊穩壓電源一定要可靠接(jie)(jie)地(di)，因不接(jie)(jie)地(di)線(xian)運(yun)行(xing)而造成的觸電或(huo)人體傷害，由用戶自行(xing)負責(ze)。

⒋穩壓電源的地線不能(neng)接在暖氣管(guan)(guan)道(dao)、供水管(guan)(guan)道(dao)、燃氣管(guan)(guan)道(dao)等(deng)公益(yi)設施上，以免侵犯第三方權(quan)利或造(zao)成危害。

⒌應定期檢查穩(wen)壓電(dian)(dian)源的輸(shu)入和(he)(he)輸(shu)出(chu)連線，以免松動或(huo)脫(tuo)落，從而影響穩(wen)壓電(dian)(dian)源的正常(chang)使用(yong)和(he)(he)用(yong)電(dian)(dian)安全。

⒍穩壓器的(de)(de)連接(jie)線(xian)的(de)(de)選配必須達(da)到規定能(neng)承載足夠的(de)(de)電流(liu)容(rong)量的(de)(de)連接(jie)線(xian)。

⒎.穩(wen)壓器應輕拿(na)輕放(fang)，在工作的時候避免(mian)劇烈振(zhen)動；

⒏、保(bao)證(zheng)穩壓(ya)(ya)器的碳(tan)刷彈簧(huang)有(you)足夠的壓(ya)(ya)力(li)，以免(mian)碳(tan)刷和線圈(quan)接觸面跳火；

⒐、非專(zhuan)業(ye)人員請不要(yao)拆開穩壓電(dian)(dian)源或對穩壓電(dian)(dian)源進行維(wei)修。
