電源適配器(qi)又稱外置電源,是一種用(yong)來為(wei)電子(zi)設備、電器(qi)的(de)供電電壓變換設備,它(ta)主要通過將電流由交流輸入轉換為(wei)直流輸出,從而為(wei)電器(qi)提(ti)供穩(wen)定(ding)的(de)電流。很(hen)多人(ren)把電源適配器(qi)和充電器(qi)混為(wei)一談,其實兩者(zhe)是不一樣的(de)。本文,就從電源適配器(qi)的(de)作(zuo)用(yong)、原理、選購、使(shi)用(yong)、保養、維(wei)修等(deng)方面來介紹下。下面,就和Maigoo小編一起(qi)來了(le)解一下吧!
電源適配器是什么
電(dian)(dian)(dian)(dian)源(yuan)適配器是(shi)一(yi)種小型便攜(xie)式(shi)電(dian)(dian)(dian)(dian)子(zi)(zi)設(she)備(bei)(bei)及電(dian)(dian)(dian)(dian)子(zi)(zi)電(dian)(dian)(dian)(dian)器的供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓變換設(she)備(bei)(bei)。常(chang)用于手機、液晶顯示器和筆記本電(dian)(dian)(dian)(dian)腦(nao)、監控等數碼產(chan)品上(shang),作為外置(zhi)電(dian)(dian)(dian)(dian)源(yuan)使(shi)用,當(dang)然也有用于工業領(ling)域(yu)。
電源適配器的作用
電源適配器(qi)作為(wei)變(bian)壓器(qi)和整(zheng)流(liu)器(qi)使用,將220v的(de)(de)家用交流(liu)電轉變(bian)為(wei)直流(liu)12v的(de)(de)電流(liu),為(wei)設備提供恒定的(de)(de)電力(li)。
電(dian)(dian)源適(shi)配(pei)器(qi)(qi)是電(dian)(dian)源到設(she)(she)備、到電(dian)(dian)池之(zhi)間的轉換系(xi)統,可以起到保護設(she)(she)備、提高電(dian)(dian)器(qi)(qi)的安全性能的作用,如果沒有電(dian)(dian)源適(shi)配(pei)器(qi)(qi),電(dian)(dian)壓不穩的話(hua)很(hen)容易導致電(dian)(dian)腦、筆記本(ben)等(deng)被燒(shao)掉。
電(dian)源適(shi)配器(qi)還(huan)能起到保護(hu)人身安(an)全的作用(yong),因(yin)為電(dian)源適(shi)配器(qi)能對輸入電(dian)流(liu)起到整(zheng)流(liu)作用(yong),能有效防止(zhi)電(dian)氣(qi)設備由(you)于輸入電(dian)流(liu)過大或電(dian)流(liu)突(tu)然中斷引起的電(dian)器(qi)爆(bao)炸、火災等事故,保護(hu)我們的人身安(an)全。
電(dian)(dian)(dian)(dian)源適(shi)配(pei)(pei)器(qi)(qi)體(ti)(ti)積都(dou)不小,通常都(dou)是(shi)外置(zhi)的(de),這(zhe)樣可以節約空(kong)間,更(geng)換也(ye)方便,并且電(dian)(dian)(dian)(dian)源適(shi)配(pei)(pei)器(qi)(qi)用的(de)市電(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)壓(ya)比(bi)較高,放機器(qi)(qi)內部比(bi)較危險(xian);不過(guo)也(ye)有部分大體(ti)(ti)積的(de)電(dian)(dian)(dian)(dian)器(qi)(qi)會將(jiang)電(dian)(dian)(dian)(dian)源適(shi)配(pei)(pei)器(qi)(qi)內置(zhi)在電(dian)(dian)(dian)(dian)器(qi)(qi)內部。電(dian)(dian)(dian)(dian)源適(shi)配(pei)(pei)器(qi)(qi)原理是(shi)將(jiang)電(dian)(dian)(dian)(dian)流由交流輸入(ru)轉換為直(zhi)流輸出(chu),把不穩定的(de)電(dian)(dian)(dian)(dian)源通過(guo)轉化電(dian)(dian)(dian)(dian)路變成電(dian)(dian)(dian)(dian)子(zi)產品需要的(de)恒(heng)壓(ya)直(zhi)流電(dian)(dian)(dian)(dian),從(cong)而給物體(ti)(ti)供(gong)電(dian)(dian)(dian)(dian)和充電(dian)(dian)(dian)(dian)。
電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)是(shi)一種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設(she)備(bei)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)變換的(de)設(she)備(bei)。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是(shi)一種(zhong)用(yong)了高頻電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)技術和先進的(de)智能(neng)動(dong)態(tai)調整充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)技術。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流模(mo)式是(shi)從(cong)交流輸入到直流輸出。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流模(mo)式使用(yong)恒(heng)流限(xian)壓充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)只是(shi)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian),而電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)不僅能(neng)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian),還能(neng)給(gei)主機(ji)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。Maigoo小編提醒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)不可以當充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)用(yong)。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(pin)(pin)牌(pai):現(xian)在網上賣的(de)很多(duo)都是偷工減(jian)料的(de)不(bu)合格產品(pin)(pin),正常使用(yong)一下應該沒問題,一旦(dan)出現(xian)意外就會燒掉(diao)你(ni)的(de)設備,省掉(diao)幾(ji)十塊卻燒掉(diao)幾(ji)千塊的(de)筆記(ji)本得不(bu)償失。
以(yi)下(xia)以(yi)筆記本電源適配(pei)器為例:
創(chuang)造(zao)良好的散熱環境(jing):在(zai)溫度較(jiao)高的環境(jing)中使(shi)用(yong)筆記本時(shi),應把(ba)電源適配(pei)器(qi)(qi)放置于不受陽(yang)光直(zhi)射(she)且通風的地方; 不要把(ba)電源適配(pei)器(qi)(qi)放在(zai)筆記本的散熱出風口附(fu)近。可以把(ba)適配(pei)器(qi)(qi)側(ce)放,還可以在(zai)適配(pei)器(qi)(qi)與桌面之(zhi)間墊入較(jiao)窄的塑料塊(kuai)(kuai)或金屬塊(kuai)(kuai)。
發生異常應及時(shi)停(ting)止使(shi)用(yong):在電源適(shi)配(pei)器發出較大工(gong)作(zuo)噪音(yin)甚至冒煙時(shi),往(wang)往(wang)是已損壞(huai)或產生故障,應立刻停(ting)止使(shi)用(yong),經專業工(gong)程師經檢修或更換。
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>>
以下以筆記本電源(yuan)適配(pei)器(qi)為例:
檢查電(dian)源適配器指標(biao)燈(deng),如果指示(shi)燈(deng)亮(liang),一般認為(wei)從電(dian)源到(dao)適配器之(zhi)間沒有問題(ti),必須保證(zheng)是指示(shi)燈(deng)本身沒壞。
檢(jian)查電(dian)源適配器到(dao)電(dian)腦之間的(de)有沒(mei)有電(dian)。這個(ge)(ge)可以通過(guo)筆記本(ben)的(de)指(zhi)示燈(deng)顯示,有電(dian)源充(chong)到(dao)筆記本(ben)的(de)時(shi)候,那個(ge)(ge)充(chong)電(dian)指(zhi)示燈(deng)會(hui)亮(liang)。否(fou)則,不會(hui)亮(liang)。或者(zhe)找一個(ge)(ge)同品牌的(de)電(dian)源適配器交換試(shi)試(shi)。
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>>
