電(dian)(dian)源(yuan)適(shi)配器(qi)又稱(cheng)外置電(dian)(dian)源(yuan),是一種用(yong)來(lai)(lai)為(wei)電(dian)(dian)子設備(bei)、電(dian)(dian)器(qi)的(de)供(gong)電(dian)(dian)電(dian)(dian)壓變換設備(bei),它主(zhu)要通過(guo)將電(dian)(dian)流由交(jiao)流輸(shu)入轉換為(wei)直流輸(shu)出,從而為(wei)電(dian)(dian)器(qi)提(ti)供(gong)穩(wen)定的(de)電(dian)(dian)流。很多人(ren)把電(dian)(dian)源(yuan)適(shi)配器(qi)和充(chong)電(dian)(dian)器(qi)混為(wei)一談(tan),其實兩者是不(bu)一樣的(de)。本文(wen),就從電(dian)(dian)源(yuan)適(shi)配器(qi)的(de)作用(yong)、原理、選購、使用(yong)、保養、維修等方面(mian)來(lai)(lai)介(jie)紹下。下面(mian),就和Maigoo小(xiao)編一起來(lai)(lai)了解(jie)一下吧!
電源適配器是什么
電(dian)源(yuan)適配器是一種(zhong)小(xiao)型(xing)便(bian)攜式電(dian)子(zi)設備及電(dian)子(zi)電(dian)器的(de)供電(dian)電(dian)壓變換(huan)設備。常用于(yu)手機、液晶顯(xian)示器和筆記本電(dian)腦、監控等數碼產(chan)品上,作(zuo)為外(wai)置電(dian)源(yuan)使用,當然也(ye)有(you)用于(yu)工(gong)業(ye)領域。
電源適配器的作用
電(dian)源適配器(qi)作(zuo)為(wei)變壓器(qi)和整流器(qi)使用(yong),將220v的(de)(de)(de)家用(yong)交流電(dian)轉變為(wei)直(zhi)流12v的(de)(de)(de)電(dian)流,為(wei)設備提供恒(heng)定的(de)(de)(de)電(dian)力。
電(dian)(dian)(dian)源適(shi)配器是電(dian)(dian)(dian)源到設備、到電(dian)(dian)(dian)池之間的(de)轉換系統,可以起到保護設備、提(ti)高電(dian)(dian)(dian)器的(de)安全(quan)性能(neng)的(de)作用,如果沒有電(dian)(dian)(dian)源適(shi)配器,電(dian)(dian)(dian)壓不(bu)穩的(de)話很容易(yi)導(dao)致電(dian)(dian)(dian)腦、筆(bi)記本等被燒掉。
電源(yuan)適配器(qi)還能(neng)起(qi)到(dao)保(bao)護人身安全的作用(yong),因為電源(yuan)適配器(qi)能(neng)對(dui)輸入(ru)電流起(qi)到(dao)整流作用(yong),能(neng)有效防止電氣設備(bei)由于輸入(ru)電流過大(da)或(huo)電流突然中(zhong)斷引起(qi)的電器(qi)爆(bao)炸(zha)、火災等(deng)事故,保(bao)護我(wo)們的人身安全。
電(dian)(dian)(dian)源適配器體(ti)積都不小,通常都是(shi)外置的,這樣可以節約空間,更換(huan)也(ye)方(fang)便,并且電(dian)(dian)(dian)源適配器用的市電(dian)(dian)(dian),電(dian)(dian)(dian)壓比較高,放機器內部比較危險;不過也(ye)有部分大體(ti)積的電(dian)(dian)(dian)器會將(jiang)電(dian)(dian)(dian)源適配器內置在(zai)電(dian)(dian)(dian)器內部。電(dian)(dian)(dian)源適配器原(yuan)理是(shi)將(jiang)電(dian)(dian)(dian)流由交(jiao)流輸入轉換(huan)為直(zhi)流輸出,把不穩定的電(dian)(dian)(dian)源通過轉化電(dian)(dian)(dian)路變成(cheng)電(dian)(dian)(dian)子產(chan)品需要的恒壓直(zhi)流電(dian)(dian)(dian),從(cong)而給物體(ti)供電(dian)(dian)(dian)和充電(dian)(dian)(dian)。
電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)是(shi)一種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)設備(bei)和電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)變換的設備(bei)。充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)一種(zhong)用了高頻電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)技術和先(xian)進的智(zhi)能動(dong)態調整充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)技術。電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)的電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)模(mo)式是(shi)從交流(liu)(liu)(liu)輸(shu)入到直(zhi)流(liu)(liu)(liu)輸(shu)出。充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)模(mo)式使用恒流(liu)(liu)(liu)限壓充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)系統。充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)只(zhi)是(shi)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian),而電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)不僅能給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian),還能給(gei)主機供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。Maigoo小編提醒電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)不可(ke)以當充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)用。詳細>>
3C認證產品:電源適配器屬于電子產品,需要經過嚴格的檢測,獲取認證標準后才能投放市場,國內一般的認證標準是3C認證。詳細>>
電源適配器功率:電源適配器功率在銘牌上都有標識。在選擇適配器的時候要注意輸出電壓和電流的大小,選擇合適功率大小的產品。Maigoo小編提醒電源適配器和原配的對比最好電壓要準確,電流可以高。詳細>>
選好品牌:現(xian)在網上賣的(de)很多都是偷工(gong)減料(liao)的(de)不(bu)合格產(chan)品,正常使用一下應(ying)該沒問題,一旦(dan)出現(xian)意外就(jiu)會(hui)燒掉(diao)你的(de)設備,省掉(diao)幾十(shi)塊卻燒掉(diao)幾千(qian)塊的(de)筆記本得不(bu)償(chang)失。
以下以筆記本電(dian)源適配(pei)器為例(li):
創(chuang)造良(liang)好的(de)(de)散(san)熱(re)環境:在(zai)溫度較(jiao)高(gao)的(de)(de)環境中使用筆(bi)記(ji)本(ben)時,應把電(dian)源適(shi)配(pei)器放(fang)置于(yu)不(bu)受陽光(guang)直射(she)且通(tong)風的(de)(de)地方(fang); 不(bu)要把電(dian)源適(shi)配(pei)器放(fang)在(zai)筆(bi)記(ji)本(ben)的(de)(de)散(san)熱(re)出(chu)風口附近。可(ke)(ke)以(yi)把適(shi)配(pei)器側放(fang),還可(ke)(ke)以(yi)在(zai)適(shi)配(pei)器與桌面之(zhi)間墊入(ru)較(jiao)窄的(de)(de)塑料塊或(huo)金(jin)屬塊。
發生異(yi)常應(ying)及(ji)時(shi)停止(zhi)使用:在電(dian)源適(shi)配器(qi)發出較大工作噪音甚至冒煙時(shi),往往是已損(sun)壞或(huo)產生故(gu)障,應(ying)立刻(ke)停止(zhi)使用,經專(zhuan)業工程(cheng)師經檢修或(huo)更換(huan)。
使用非原裝的電源要謹慎:非原裝的電源適配器在輸出接口、電壓和電流值等方面都可能存在一些差異(或者是標稱與實際不符),如果匹配不當,可能會影響筆記本運行的穩定性。另外,相同品牌不同型號的筆記本的電源適配器在換用時也應慎重。詳細>>
以下以筆記(ji)本(ben)電源適配器為例:
檢查(cha)電源適配(pei)(pei)器指標燈,如果指示(shi)燈亮,一般認為從電源到適配(pei)(pei)器之間(jian)沒(mei)有問題,必須保證是(shi)指示(shi)燈本身(shen)沒(mei)壞。
檢查電源適配(pei)器到電腦之間的(de)(de)有沒有電。這個(ge)可以通過筆(bi)記(ji)本的(de)(de)指示燈(deng)顯示,有電源充到筆(bi)記(ji)本的(de)(de)時(shi)候,那個(ge)充電指示燈(deng)會亮(liang)。否則,不會亮(liang)。或者找(zhao)一個(ge)同品牌的(de)(de)電源適配(pei)器交換試試。
觀測電腦的指示燈變化。如果你插上電源適配器后,你可以看到充電的指示燈時亮時滅,有時間一直不滅,則是筆記本里面那個電源適配器接口有問題,一般可能里面線斷了,電路板老化,焊接掉落等原因。詳細>>
