穩壓器工作原理 穩壓器的作用有哪些

穩(wen)壓器工作原理(li)

由(you)于部分電(dian)(dian)器中含有線(xian)圈組(zu)(zu)件，在通電(dian)(dian)初期會(hui)產(chan)生阻礙(ai)電(dian)(dian)流的(de)(de)(de)渦流，渦流的(de)(de)(de)產(chan)生既會(hui)削(xue)弱到電(dian)(dian)器啟動(dong)(dong)(dong)時(shi)(shi)的(de)(de)(de)瞬時(shi)(shi)電(dian)(dian)壓(ya)(ya)，導致啟動(dong)(dong)(dong)緩慢，又(you)會(hui)加強斷路(lu)后產(chan)生的(de)(de)(de)瞬時(shi)(shi)電(dian)(dian)壓(ya)(ya)，可能產(chan)生火花損壞電(dian)(dian)路(lu)。此時(shi)(shi)便(bian)需要一個(ge)穩(wen)壓(ya)(ya)器來(lai)保(bao)護電(dian)(dian)路(lu)的(de)(de)(de)正常運行(xing)。穩(wen)壓(ya)(ya)器由(you)調(diao)壓(ya)(ya)電(dian)(dian)路(lu)、控制(zhi)電(dian)(dian)路(lu)、及伺服電(dian)(dian)機等組(zu)(zu)成，當輸入電(dian)(dian)壓(ya)(ya)或負載變(bian)化(hua)時(shi)(shi)，控制(zhi)電(dian)(dian)路(lu)進(jin)行(xing)取樣(yang)、比較(jiao)、放大，然(ran)后驅動(dong)(dong)(dong)伺服電(dian)(dian)機轉動(dong)(dong)(dong)，使調(diao)壓(ya)(ya)器碳(tan)刷的(de)(de)(de)位置改(gai)變(bian)，通過自動(dong)(dong)(dong)調(diao)整線(xian)圈匝數比，從而保(bao)持輸出電(dian)(dian)壓(ya)(ya)的(de)(de)(de)穩(wen)定。容量較(jiao)大的(de)(de)(de)穩(wen)壓(ya)(ya)器，還采用電(dian)(dian)壓(ya)(ya)補償的(de)(de)(de)原理工(gong)作。

穩壓器的作用

穩(wen)壓器是(shi)(shi)一種能自動(dong)調(diao)整輸出(chu)電(dian)(dian)(dian)壓的供電(dian)(dian)(dian)電(dian)(dian)(dian)路或(huo)供電(dian)(dian)(dian)設(she)備(bei)，其(qi)作(zuo)用是(shi)(shi)將波動(dong)較(jiao)大和達不(bu)到(dao)電(dian)(dian)(dian)器設(she)備(bei)要求的電(dian)(dian)(dian)源電(dian)(dian)(dian)壓穩(wen)定(ding)(ding)在它的設(she)定(ding)(ding)值范圍(wei)內，使各(ge)種電(dian)(dian)(dian)路或(huo)電(dian)(dian)(dian)器設(she)備(bei)能在額定(ding)(ding)工作(zuo)電(dian)(dian)(dian)壓下(xia)正(zheng)常工作(zuo)。

最(zui)初的電(dian)(dian)(dian)(dian)(dian)(dian)力穩壓(ya)(ya)(ya)(ya)器(qi)是(shi)(shi)靠(kao)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的跳(tiao)動(dong)穩定電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)的。當電(dian)(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)出現波(bo)動(dong)時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)力穩壓(ya)(ya)(ya)(ya)器(qi)的自(zi)動(dong)糾正(zheng)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)啟動(dong)，使內部繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)動(dong)作。迫使輸出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)保持在設定值附近，這(zhe)種電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)優點是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)簡單，缺點是(shi)(shi)穩壓(ya)(ya)(ya)(ya)精(jing)度不(bu)高并且每一次(ci)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)跳(tiao)動(dong)換擋，都會(hui)使供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源發生一次(ci)瞬時(shi)的中斷(duan)并產生火(huo)花干擾。

這對電腦設備(bei)的(de)讀寫工作干擾很大，容易造(zao)成電腦出(chu)現錯(cuo)誤信號(hao)，嚴重時還會使硬盤損壞。

高質量的小型穩壓器(qi)，大多采(cai)用電(dian)機拖動(dong)碳刷的方法穩定電(dian)壓，這種穩壓器(qi)對電(dian)器(qi)設(she)備產生的干擾很(hen)小穩壓精度相(xiang)對較(jiao)高。

安全事宜

⒈穩壓(ya)電(dian)(dian)(dian)源(yuan)在通電(dian)(dian)(dian)啟動時，請勿(wu)隨意(yi)拆開(kai)穩壓(ya)電(dian)(dian)(dian)源(yuan)或(huo)撥拉(la)穩壓(ya)電(dian)(dian)(dian)源(yuan)輸入輸出連線，以(yi)防觸電(dian)(dian)(dian)或(huo)其它電(dian)(dian)(dian)氣安(an)全事故。

⒉穩(wen)壓電源輸入(ru)輸出連線一(yi)定要布置合理，防止踩踏磨破，造成(cheng)漏電事故。

⒊穩壓(ya)電源一定要可(ke)靠接地，因不接地線(xian)運行(xing)而造成(cheng)的(de)觸電或人體傷害，由(you)用(yong)戶自行(xing)負責(ze)。

⒋穩壓(ya)電源(yuan)的(de)地線(xian)不能接在(zai)暖氣管(guan)(guan)道(dao)(dao)、供水管(guan)(guan)道(dao)(dao)、燃氣管(guan)(guan)道(dao)(dao)等公益設施(shi)上，以(yi)免侵犯第三方權利或(huo)造成危(wei)害。

⒌應定期(qi)檢查(cha)穩壓(ya)電(dian)(dian)(dian)源的輸(shu)入和輸(shu)出連線(xian)，以免松動或脫落，從而影響穩壓(ya)電(dian)(dian)(dian)源的正常使用和用電(dian)(dian)(dian)安全。

⒍穩壓器(qi)的連接(jie)線的選(xuan)配必(bi)須達到規定(ding)能承載足夠的電流容量的連接(jie)線。

⒎.穩壓器應(ying)輕(qing)拿輕(qing)放，在工作的(de)時(shi)候(hou)避免劇烈振動；

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

⒐、非專業人員請不(bu)要拆開穩壓電(dian)源或(huo)對穩壓電(dian)源進行維修。
