穩壓(ya)器工作原理

由于部分電(dian)(dian)器(qi)中含(han)有(you)線(xian)圈組件，在通電(dian)(dian)初期會產生(sheng)(sheng)阻礙電(dian)(dian)流的渦流，渦流的產生(sheng)(sheng)既會削(xue)弱到電(dian)(dian)器(qi)啟動(dong)時的瞬時電(dian)(dian)壓(ya)(ya)(ya)(ya)，導致(zhi)啟動(dong)緩慢，又會加(jia)強斷路(lu)后產生(sheng)(sheng)的瞬時電(dian)(dian)壓(ya)(ya)(ya)(ya)，可能產生(sheng)(sheng)火花損壞(huai)電(dian)(dian)路(lu)。此(ci)時便需(xu)要一個穩(wen)壓(ya)(ya)(ya)(ya)器(qi)來保(bao)護電(dian)(dian)路(lu)的正常運行(xing)。穩(wen)壓(ya)(ya)(ya)(ya)器(qi)由調壓(ya)(ya)(ya)(ya)電(dian)(dian)路(lu)、控制(zhi)電(dian)(dian)路(lu)、及伺(si)服電(dian)(dian)機(ji)等組成，當輸(shu)入(ru)電(dian)(dian)壓(ya)(ya)(ya)(ya)或負載(zai)變化時，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)伺(si)服電(dian)(dian)機(ji)轉動(dong)，使調壓(ya)(ya)(ya)(ya)器(qi)碳刷的位(wei)置改變，通過自動(dong)調整線(xian)圈匝數比，從(cong)而保(bao)持輸(shu)出電(dian)(dian)壓(ya)(ya)(ya)(ya)的穩(wen)定。容量較(jiao)大的穩(wen)壓(ya)(ya)(ya)(ya)器(qi)，還采用電(dian)(dian)壓(ya)(ya)(ya)(ya)補(bu)償的原理工作。

穩壓器的作用

穩壓(ya)器是一種能自動(dong)調(diao)整輸出電(dian)(dian)壓(ya)的(de)(de)供(gong)電(dian)(dian)電(dian)(dian)路或(huo)供(gong)電(dian)(dian)設備，其(qi)作(zuo)用是將波動(dong)較大和達不到電(dian)(dian)器設備要求的(de)(de)電(dian)(dian)源電(dian)(dian)壓(ya)穩定(ding)在(zai)它的(de)(de)設定(ding)值范圍(wei)內(nei)，使各種電(dian)(dian)路或(huo)電(dian)(dian)器設備能在(zai)額定(ding)工(gong)作(zuo)電(dian)(dian)壓(ya)下正常工(gong)作(zuo)。

最初的(de)電(dian)(dian)(dian)力穩(wen)壓(ya)(ya)器是(shi)靠繼(ji)電(dian)(dian)(dian)器的(de)跳動(dong)穩(wen)定電(dian)(dian)(dian)壓(ya)(ya)的(de)。當電(dian)(dian)(dian)網電(dian)(dian)(dian)壓(ya)(ya)出現波動(dong)時(shi)，電(dian)(dian)(dian)力穩(wen)壓(ya)(ya)器的(de)自動(dong)糾正(zheng)電(dian)(dian)(dian)路(lu)(lu)啟動(dong)，使內(nei)部繼(ji)電(dian)(dian)(dian)器動(dong)作。迫使輸出電(dian)(dian)(dian)壓(ya)(ya)保持在設(she)定值附近，這種電(dian)(dian)(dian)路(lu)(lu)優點是(shi)電(dian)(dian)(dian)路(lu)(lu)簡單，缺點是(shi)穩(wen)壓(ya)(ya)精度不(bu)高并且(qie)每(mei)一次繼(ji)電(dian)(dian)(dian)器跳動(dong)換擋，都會使供電(dian)(dian)(dian)電(dian)(dian)(dian)源發生(sheng)一次瞬時(shi)的(de)中斷并產生(sheng)火(huo)花干擾。

這對(dui)電腦(nao)設備的讀寫工作(zuo)干(gan)擾很大，容易造成電腦(nao)出現錯誤信號，嚴重時還(huan)會使硬盤損壞。

高質量的小(xiao)型(xing)穩壓器，大多采(cai)用(yong)電(dian)(dian)機拖動碳刷(shua)的方(fang)法穩定電(dian)(dian)壓，這(zhe)種(zhong)穩壓器對(dui)電(dian)(dian)器設(she)備產生的干擾很小(xiao)穩壓精度相對(dui)較高。

安全事宜

⒈穩(wen)壓(ya)電(dian)源在通(tong)電(dian)啟動時，請勿隨(sui)意(yi)拆開(kai)穩(wen)壓(ya)電(dian)源或撥(bo)拉穩(wen)壓(ya)電(dian)源輸(shu)入輸(shu)出連線，以防觸電(dian)或其它電(dian)氣安(an)全事故。

⒉穩(wen)壓(ya)電源輸入(ru)輸出(chu)連(lian)線一定(ding)要(yao)布置合(he)理，防止(zhi)踩踏磨破，造成漏電事(shi)故。

⒊穩壓電(dian)源一定(ding)要可靠接地，因不接地線運行而(er)造成的觸電(dian)或人體傷(shang)害(hai)，由用戶自行負責(ze)。

⒋穩(wen)壓(ya)電源的地線不能接在暖(nuan)氣(qi)管道、供(gong)水管道、燃氣(qi)管道等公益設施(shi)上(shang)，以(yi)免侵犯第三方(fang)權(quan)利或造成(cheng)危害(hai)。

⒌應定期檢查穩壓電(dian)(dian)源的輸(shu)入(ru)和輸(shu)出(chu)連線(xian)，以免松動或脫落，從而影響穩壓電(dian)(dian)源的正常使用和用電(dian)(dian)安全。

⒍穩壓器的(de)連接(jie)線的(de)選配必(bi)須達到(dao)規定能(neng)承載足夠(gou)的(de)電流容量的(de)連接(jie)線。

⒎.穩壓器(qi)應輕拿輕放，在工(gong)作(zuo)的時(shi)候避免劇烈(lie)振動；

⒏、保證(zheng)穩壓(ya)器的(de)碳刷彈簧有足夠(gou)的(de)壓(ya)力，以免碳刷和線圈接觸面跳火；

⒐、非專業人員請不要拆開穩壓電(dian)源(yuan)或對穩壓電(dian)源(yuan)進行(xing)維修(xiu)。
