穩壓器工作(zuo)原理

由于部分電(dian)(dian)(dian)器中(zhong)含有線(xian)圈組件，在通電(dian)(dian)(dian)初期(qi)會(hui)產(chan)(chan)生(sheng)(sheng)阻礙電(dian)(dian)(dian)流的(de)(de)渦流，渦流的(de)(de)產(chan)(chan)生(sheng)(sheng)既會(hui)削弱到電(dian)(dian)(dian)器啟動時(shi)(shi)的(de)(de)瞬時(shi)(shi)電(dian)(dian)(dian)壓(ya)(ya)(ya)，導致啟動緩慢(man)，又會(hui)加強斷(duan)路后(hou)產(chan)(chan)生(sheng)(sheng)的(de)(de)瞬時(shi)(shi)電(dian)(dian)(dian)壓(ya)(ya)(ya)，可能產(chan)(chan)生(sheng)(sheng)火(huo)花損壞電(dian)(dian)(dian)路。此(ci)時(shi)(shi)便需要一(yi)個穩(wen)(wen)壓(ya)(ya)(ya)器來(lai)保護電(dian)(dian)(dian)路的(de)(de)正(zheng)常(chang)運行。穩(wen)(wen)壓(ya)(ya)(ya)器由調壓(ya)(ya)(ya)電(dian)(dian)(dian)路、控制(zhi)(zhi)電(dian)(dian)(dian)路、及(ji)伺(si)服電(dian)(dian)(dian)機(ji)等組成，當輸入電(dian)(dian)(dian)壓(ya)(ya)(ya)或負(fu)載變(bian)化(hua)時(shi)(shi)，控制(zhi)(zhi)電(dian)(dian)(dian)路進行取樣、比(bi)較(jiao)、放大，然后(hou)驅(qu)動伺(si)服電(dian)(dian)(dian)機(ji)轉動，使調壓(ya)(ya)(ya)器碳刷的(de)(de)位置(zhi)改變(bian)，通過自動調整線(xian)圈匝(za)數比(bi)，從(cong)而(er)保持輸出(chu)電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)穩(wen)(wen)定。容(rong)量較(jiao)大的(de)(de)穩(wen)(wen)壓(ya)(ya)(ya)器，還采用電(dian)(dian)(dian)壓(ya)(ya)(ya)補償的(de)(de)原理(li)工作。

穩壓器的作用

穩壓(ya)器是一種(zhong)能自動調整(zheng)輸(shu)出(chu)電(dian)(dian)壓(ya)的(de)供電(dian)(dian)電(dian)(dian)路(lu)或供電(dian)(dian)設(she)(she)備，其作(zuo)用是將波動較大和達不到電(dian)(dian)器設(she)(she)備要求的(de)電(dian)(dian)源電(dian)(dian)壓(ya)穩定(ding)在(zai)它的(de)設(she)(she)定(ding)值范圍(wei)內，使(shi)各種(zhong)電(dian)(dian)路(lu)或電(dian)(dian)器設(she)(she)備能在(zai)額定(ding)工(gong)作(zuo)電(dian)(dian)壓(ya)下(xia)正常工(gong)作(zuo)。

最初的電(dian)(dian)(dian)(dian)(dian)力穩(wen)壓(ya)器(qi)(qi)(qi)是靠(kao)繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的跳動(dong)穩(wen)定(ding)電(dian)(dian)(dian)(dian)(dian)壓(ya)的。當電(dian)(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)(dian)壓(ya)出現波(bo)動(dong)時(shi)，電(dian)(dian)(dian)(dian)(dian)力穩(wen)壓(ya)器(qi)(qi)(qi)的自(zi)動(dong)糾正電(dian)(dian)(dian)(dian)(dian)路啟動(dong)，使(shi)內(nei)部繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)動(dong)作(zuo)。迫使(shi)輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)保(bao)持(chi)在(zai)設定(ding)值附近，這(zhe)種(zhong)電(dian)(dian)(dian)(dian)(dian)路優點(dian)是電(dian)(dian)(dian)(dian)(dian)路簡單，缺點(dian)是穩(wen)壓(ya)精度不高(gao)并且每(mei)一(yi)次繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)跳動(dong)換擋，都會使(shi)供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源發生一(yi)次瞬時(shi)的中斷并產生火花干擾。

這對電腦(nao)設備的讀寫工作干擾很大，容易造成電腦(nao)出現錯誤(wu)信號(hao)，嚴重時還會(hui)使硬盤損壞。

高質量的(de)小(xiao)型穩(wen)(wen)壓器，大(da)多采用(yong)電(dian)機拖動碳刷的(de)方法穩(wen)(wen)定(ding)電(dian)壓，這(zhe)種穩(wen)(wen)壓器對電(dian)器設備產(chan)生的(de)干擾(rao)很(hen)小(xiao)穩(wen)(wen)壓精度相對較高。

安全事宜

⒈穩(wen)(wen)壓電源在通(tong)電啟動時，請勿隨意拆開穩(wen)(wen)壓電源或(huo)(huo)撥拉穩(wen)(wen)壓電源輸入(ru)輸出連線，以防觸電或(huo)(huo)其它電氣安全(quan)事(shi)故。

⒉穩壓電源(yuan)輸入輸出(chu)連線一定要布置(zhi)合(he)理，防止踩踏磨破，造成(cheng)漏(lou)電事故。

⒊穩(wen)壓電源(yuan)一(yi)定要可靠接(jie)地(di)，因(yin)不接(jie)地(di)線運行而造成的(de)觸電或人(ren)體(ti)傷(shang)害，由(you)用戶自行負責。

⒋穩壓電源的地線不能接在暖氣管(guan)道、供水管(guan)道、燃(ran)氣管(guan)道等公益設施上(shang)，以免侵犯第三方(fang)權利或造(zao)成(cheng)危害。

⒌應(ying)定期檢查穩壓電源的輸入和輸出連線，以免松動或脫落，從而影響穩壓電源的正常使(shi)用(yong)和用(yong)電安全。

⒍穩壓器的(de)連(lian)接(jie)線的(de)選配必須(xu)達到規定能承載足夠(gou)的(de)電流容量的(de)連(lian)接(jie)線。

⒎.穩壓器應輕(qing)拿輕(qing)放，在(zai)工作的(de)時候避免劇烈振動(dong)；

⒏、保證穩壓器(qi)的碳刷彈簧有足夠的壓力，以(yi)免(mian)碳刷和線圈接(jie)觸面(mian)跳火；

⒐、非專業(ye)人員請不要拆開穩(wen)壓(ya)電源或(huo)對穩(wen)壓(ya)電源進行(xing)維修。
