穩壓器工作原(yuan)理

由于部分(fen)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)中含(han)有(you)線圈(quan)組(zu)件，在通(tong)電(dian)(dian)(dian)(dian)(dian)初期會產(chan)生阻礙電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的渦流(liu)(liu)，渦流(liu)(liu)的產(chan)生既會削(xue)弱到電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)啟動(dong)時(shi)的瞬時(shi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，導致(zhi)啟動(dong)緩慢，又會加(jia)強(qiang)斷(duan)路(lu)后產(chan)生的瞬時(shi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，可(ke)能產(chan)生火(huo)花損壞電(dian)(dian)(dian)(dian)(dian)路(lu)。此(ci)時(shi)便(bian)需要一個穩(wen)壓(ya)(ya)(ya)器(qi)(qi)來保護電(dian)(dian)(dian)(dian)(dian)路(lu)的正(zheng)常運(yun)行。穩(wen)壓(ya)(ya)(ya)器(qi)(qi)由調(diao)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)路(lu)、控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)路(lu)、及(ji)伺(si)服電(dian)(dian)(dian)(dian)(dian)機(ji)等組(zu)成，當輸(shu)入電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)或(huo)負載變(bian)化時(shi)，控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)路(lu)進(jin)行取樣、比較(jiao)、放(fang)大，然(ran)后驅動(dong)伺(si)服電(dian)(dian)(dian)(dian)(dian)機(ji)轉動(dong)，使調(diao)壓(ya)(ya)(ya)器(qi)(qi)碳(tan)刷的位置改變(bian)，通(tong)過自動(dong)調(diao)整線圈(quan)匝(za)數(shu)比，從而保持輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的穩(wen)定(ding)。容(rong)量較(jiao)大的穩(wen)壓(ya)(ya)(ya)器(qi)(qi)，還采用電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)補償(chang)的原(yuan)理工作(zuo)。

穩壓器的作用

穩壓(ya)器(qi)是一種能(neng)自動(dong)調整輸出電(dian)(dian)壓(ya)的供電(dian)(dian)電(dian)(dian)路(lu)或供電(dian)(dian)設(she)備，其作用(yong)是將波動(dong)較大和達不到電(dian)(dian)器(qi)設(she)備要(yao)求的電(dian)(dian)源電(dian)(dian)壓(ya)穩定(ding)在它的設(she)定(ding)值范(fan)圍(wei)內，使各(ge)種電(dian)(dian)路(lu)或電(dian)(dian)器(qi)設(she)備能(neng)在額(e)定(ding)工作電(dian)(dian)壓(ya)下正常工作。

最初的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力穩(wen)(wen)壓器是(shi)靠(kao)繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)(de)跳動穩(wen)(wen)定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)(de)。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓出現波動時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力穩(wen)(wen)壓器的(de)(de)(de)自(zi)動糾正電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)啟動，使(shi)內部繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器動作。迫使(shi)輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓保持在設定(ding)值附(fu)近(jin)，這種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)優點是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)簡單(dan)，缺(que)點是(shi)穩(wen)(wen)壓精度不高并(bing)且每(mei)一次繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器跳動換擋，都會使(shi)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源發生(sheng)(sheng)一次瞬時的(de)(de)(de)中斷并(bing)產(chan)生(sheng)(sheng)火花(hua)干擾。

這對電腦設備的(de)讀寫工(gong)作干擾很(hen)大，容易造成電腦出現錯誤信號，嚴重時還(huan)會使硬盤損壞。

高質量的(de)小型穩(wen)壓(ya)(ya)器(qi)，大多采用電機拖動碳刷的(de)方法穩(wen)定電壓(ya)(ya)，這種穩(wen)壓(ya)(ya)器(qi)對電器(qi)設備(bei)產生的(de)干擾(rao)很小穩(wen)壓(ya)(ya)精度相對較(jiao)高。

安全事宜

⒈穩壓電源在通電啟動時，請勿隨意拆開(kai)穩壓電源或撥拉穩壓電源輸(shu)(shu)入(ru)輸(shu)(shu)出連線，以防(fang)觸(chu)電或其它電氣(qi)安全事故。

⒉穩(wen)壓電源輸(shu)入輸(shu)出連線一定(ding)要布置合(he)理，防止(zhi)踩踏(ta)磨(mo)破，造成漏(lou)電事故。

⒊穩壓電源(yuan)一定要(yao)可(ke)靠接(jie)地(di)，因不接(jie)地(di)線運行而造成的觸電或(huo)人體(ti)傷害，由用戶自行負責。

⒋穩壓電(dian)源的地線不能(neng)接(jie)在暖(nuan)氣(qi)管(guan)道(dao)(dao)、供水(shui)管(guan)道(dao)(dao)、燃氣(qi)管(guan)道(dao)(dao)等公益(yi)設施上(shang)，以免侵犯第三方權利(li)或造成危害。

⒌應定期(qi)檢查穩壓電源(yuan)的輸入和輸出連(lian)線，以免松動或脫落，從而影響穩壓電源(yuan)的正常使用(yong)和用(yong)電安全。

⒍穩壓器(qi)的(de)連接(jie)線(xian)的(de)選配(pei)必須(xu)達到規定能承載(zai)足(zu)夠的(de)電流(liu)容(rong)量的(de)連接(jie)線(xian)。

⒎.穩壓器(qi)應輕(qing)拿輕(qing)放，在(zai)工作的時候避(bi)免劇烈振(zhen)動；

⒏、保證穩壓器的(de)碳刷(shua)彈簧有(you)足(zu)夠的(de)壓力，以(yi)免碳刷(shua)和線圈接觸面跳火；

⒐、非(fei)專業人員請不要拆(chai)開穩壓電源或對穩壓電源進行維修。
