【機箱(xiang)漏電(dian)(dian)】電(dian)(dian)腦機箱(xiang)漏電(dian)(dian)怎么回事 機箱(xiang)漏電(dian)(dian)的處理方(fang)法
一般來說機箱漏(lou)電的原因比較多,不過問題(ti)集中(zhong)在以下幾個方(fang)面。
⒈)外在原因導致電腦機箱漏電
有些時(shi)候(hou)電(dian)(dian)腦存在漏(lou)(lou)電(dian)(dian)也可(ke)能(neng)并不是(shi)電(dian)(dian)腦機(ji)(ji)(ji)箱(xiang)(xiang)內部的(de)(de)主(zhu)板或者(zhe)電(dian)(dian)源漏(lou)(lou)電(dian)(dian)導(dao)(dao)致(zhi)的(de)(de),有的(de)(de)時(shi)候(hou)會(hui)發現機(ji)(ji)(ji)箱(xiang)(xiang)漏(lou)(lou)電(dian)(dian)是(shi)由于外在原因(yin)導(dao)(dao)致(zhi)的(de)(de),比(bi)如機(ji)(ji)(ji)箱(xiang)(xiang)與(yu)別的(de)(de)電(dian)(dian)器(qi)放置(zhi)的(de)(de)過(guo)近或者(zhe)機(ji)(ji)(ji)箱(xiang)(xiang)觸(chu)碰到(dao)破皮的(de)(de)電(dian)(dian)線(xian)等(deng)等(deng),從(cong)而(er)導(dao)(dao)致(zhi)機(ji)(ji)(ji)箱(xiang)(xiang)漏(lou)(lou)電(dian)(dian)。對于這(zhe)種外在原因(yin)導(dao)(dao)致(zhi)的(de)(de)機(ji)(ji)(ji)箱(xiang)(xiang)漏(lou)(lou)電(dian)(dian),其(qi)實解決辦法很簡(jian)單,當我們發現機(ji)(ji)(ji)箱(xiang)(xiang)存在漏(lou)(lou)電(dian)(dian)時(shi),檢(jian)查下電(dian)(dian)腦機(ji)(ji)(ji)箱(xiang)(xiang)附(fu)近有沒有什(shen)么(me)(me)電(dian)(dian)器(qi)或者(zhe)碰到(dao)什(shen)么(me)(me)電(dian)(dian)線(xian)等(deng),移動下位置(zhi)即(ji)可(ke)解決。
⒉)內在原因導致電腦機箱漏電
內(nei)在原因導(dao)致電(dian)(dian)腦(nao)機(ji)箱(xiang)漏電(dian)(dian)是(shi)最常見的(de)(de)電(dian)(dian)腦(nao)漏電(dian)(dian)情況,那么電(dian)(dian)腦(nao)機(ji)箱(xiang)內(nei)部哪(na)些(xie)硬(ying)件(jian)容易漏電(dian)(dian)呢(ni)?這個其實(shi)也很好(hao)知道,主(zhu)要找到(dao)(dao)哪(na)些(xie)硬(ying)件(jian)與機(ji)箱(xiang)有接觸即可,比如(ru)電(dian)(dian)源是(shi)最容易導(dao)致機(ji)箱(xiang)漏電(dian)(dian)的(de)(de),另外一個就是(shi)主(zhu)板如(ru)果安裝(zhuang)不到(dao)(dao)位或(huo)(huo)者,或(huo)(huo)者某(mou)些(xie)元件(jian)引腳碰(peng)帶機(ji)箱(xiang)外殼了也容易出現(xian)漏電(dian)(dian)現(xian)象(xiang)。
在電(dian)(dian)腦(nao)(nao)機(ji)(ji)箱(xiang)(xiang)漏(lou)(lou)電(dian)(dian)中(zhong),往往出(chu)現(xian)在一些使(shi)用(yong)(yong)較(jiao)久的(de)(de)電(dian)(dian)腦(nao)(nao)上(shang),這是因為一般新電(dian)(dian)腦(nao)(nao)機(ji)(ji)箱(xiang)(xiang)電(dian)(dian)源內部方(fang)面都比(bi)較(jiao)正常,一般不會出(chu)現(xian)漏(lou)(lou)電(dian)(dian)想(xiang)象。但如果電(dian)(dian)源使(shi)用(yong)(yong)過度,或者(zhe)遇到天氣(qi)潮(chao)濕等惡劣氣(qi)候環(huan)(huan)境(jing)(jing),破壞了電(dian)(dian)源內部本身良好(hao)的(de)(de)“環(huan)(huan)境(jing)(jing)”,漏(lou)(lou)電(dian)(dian)也會隨之(zhi)而(er)產(chan)(chan)生,比(bi)較(jiao)常見的(de)(de)是電(dian)(dian)源內部由于(yu)灰塵(chen)過多(duo),加之(zhi)潮(chao)濕導致內部元件之(zhi)間與電(dian)(dian)源金屬外殼之(zhi)間形成(cheng)通(tong)路,導致漏(lou)(lou)電(dian)(dian),而(er)電(dian)(dian)源往往是緊貼(tie)著機(ji)(ji)箱(xiang)(xiang)的(de)(de),因此老(lao)電(dian)(dian)腦(nao)(nao)很(hen)容易(yi)產(chan)(chan)生漏(lou)(lou)電(dian)(dian)現(xian)象。
電源漏電是最常見的導致機箱漏電
還有(you)的(de)就是(shi),平臺內部(bu)的(de)每一個(ge)配件,都有(you)可能產(chan)生漏電(dian)(dian)狀況,而(er)引致(zhi)我們在平臺外(wai)部(bu)觸(chu)碰機箱(xiang),而(er)有(you)了漏電(dian)(dian)的(de)感(gan)覺(jue)。而(er)這種漏電(dian)(dian)的(de)情(qing)況,其實同樣來自于用戶所(suo)使用的(de)電(dian)(dian)插板,沒(mei)有(you)完善的(de)接(jie)地(di)設計,導致(zhi)平臺內部(bu)元(yuan)件所(suo)產(chan)生的(de)漏電(dian)(dian)效應,無法(fa)通過接(jie)地(di)而(er)將漏電(dian)(dian)引導大地(di)當中,降低漏電(dian)(dian)的(de)危(wei)險。
電腦機箱漏電怎么辦?
我(wo)們知(zhi)道人(ren)(ren)體(ti)接觸的安全(quan)電(dian)壓(ya)低于36度,即可認為對人(ren)(ren)體(ti)安全(quan)影響不(bu)大(da),而電(dian)腦內部所使用的電(dian)壓(ya)均為小于12V,因此一(yi)般的電(dian)腦漏電(dian)不(bu)會對人(ren)(ren)體(ti)造(zao)成傷害,但(dan)經常碰到機箱有發麻的被電(dian)感覺,估計誰也受不(bu)了,那么(me)機箱漏電(dian)怎么(me)解決呢?一(yi)般可以(yi)參考以(yi)下(xia)方法:
1、發現(xian)漏(lou)電,我們首先要確認自己所(suo)使用的電插板是否有良好的接(jie)地設計,如(ru)果(guo)沒有馬上更(geng)換(包括家(jia)居中較(jiao)為常見(jian)的入墻式(shi)電插座),有了良好的接(jie)地,即(ji)便是產生(sheng)漏(lou)電,也(ye)能把傷害(hai)和損失減到最(zui)少(shao)。
2、打開機箱,看看機箱內外的(de)(de)接線,絕緣(yuan)包(bao)裹有(you)沒有(you)破損,線材(cai)的(de)(de)金屬部分(fen)有(you)沒有(you)裸露而接觸到(dao)其他配件及機箱,有(you)則(ze)馬上予以更換。或者直(zhi)接選擇有(you)尼龍網包(bao)裹的(de)(de)線材(cai),這樣也能起到(dao)較(jiao)好(hao)的(de)(de)絕緣(yuan)效果。
3、排除了(le)線(xian)材和(he)插(cha)座接地(di)的(de)(de)問題,鑒于前(qian)面的(de)(de)分(fen)析,產生機箱漏電(dian)(dian)(dian)(dian)(dian)幾率最大(da)的(de)(de)元(yuan)(yuan)兇(xiong)是(shi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan),我們(men)就從(cong)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)方面去著手,拆開電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan),看看電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)EMI電(dian)(dian)(dian)(dian)(dian)路是(shi)否完整,間(jian)隔元(yuan)(yuan)件(jian)與電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)金屬外(wai)殼之(zhi)間(jian)的(de)(de)塑料薄膜片(pian)或(huo)者云母片(pian)有沒(mei)有失去絕緣的(de)(de)功效,電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)內(nei)部電(dian)(dian)(dian)(dian)(dian)容等(deng)有沒(mei)有出(chu)現爆(bao)漿(jiang)等(deng)情況,如出(chu)現問題,可(ke)以自行打造(zao)一張(zhang)耐高溫的(de)(de)塑料薄膜,在元(yuan)(yuan)件(jian)和(he)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)外(wai)殼之(zhi)間(jian)形成屏蔽阻(zu)隔,如不能(neng)解決則馬上更換(huan)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)。
4、最后檢查(cha)機箱(xiang)內部的(de)主板(ban)、顯卡,檢查(cha)有沒有出(chu)現PCB板(ban)變形等情況(kuang)導致(zhi)與機箱(xiang)直(zhi)接接觸(chu)。檢查(cha)的(de)方法最好(hao)使用最小(xiao)化(hua)系統,一方面(mian)讓平臺更加簡單容易(yi)判斷,另一方面(mian)可以避免硬盤等配件測(ce)試過(guo)程中的(de)不(bu)必要(yao)損壞(huai)。
5、最(zui)后(hou)檢(jian)查機(ji)箱本身,一般的(de)機(ji)箱前面板(ban)后(hou)方,都有(you)一個(ge)連接主板(ban)音頻、信號、開關、USB擴展的(de)PCB電(dian)路(lu)板(ban),我們也需要檢(jian)查該(gai)電(dian)路(lu)板(ban)以及(ji)連接電(dian)路(lu)板(ban)上(shang)的(de)線(xian)材有(you)沒有(you)出(chu)現絕(jue)緣失效、元件短路(lu)、燒毀(hui)的(de)情況,如有(you),可借(jie)助簡單的(de)電(dian)工(gong)常識(shi)和電(dian)工(gong)工(gong)具將(jiang)其(qi)修復或(huo)更換。
6、當然,我(wo)們(men)還可以通過將機箱放置(zhi)到較為干爽(shuang)位置(zhi)(如原(yuan)來安放位置(zhi)較為潮濕容易引起電線短路),更(geng)換底部絕(jue)緣的鞋(xie)子等方(fang)法,進行全范圍的判斷,最終找(zhao)出漏電元兇。
電腦機箱漏電的解決辦法
對于一般問(wen)題不嚴重(zhong)的漏(lou)電(dian)情況,新手朋友還(huan)可(ke)(ke)(ke)以(yi)拿(na)一根導線將(jiang)機(ji)箱與(yu)金(jin)屬接(jie)(jie)(jie)地(di)物(wu)體(ti)連接(jie)(jie)(jie),放掉漏(lou)電(dian)即(ji)可(ke)(ke)(ke),注意接(jie)(jie)(jie)地(di)一頭(tou)你可(ke)(ke)(ke)以(yi)接(jie)(jie)(jie)到暖氣片上(shang)(shang)額也可(ke)(ke)(ke)以(yi)接(jie)(jie)(jie)到鋁合金(jin)窗戶上(shang)(shang)等大(da)面積金(jin)屬接(jie)(jie)(jie)地(di)物(wu)體(ti)上(shang)(shang),直(zhi)接(jie)(jie)(jie)接(jie)(jie)(jie)地(di)板(ban)上(shang)(shang)效(xiao)果不好(hao),可(ke)(ke)(ke)能還(huan)會有機(ji)箱漏(lou)電(dian)的感覺,因(yin)此(ci)最好(hao)連接(jie)(jie)(jie)接(jie)(jie)(jie)地(di)的金(jin)屬物(wu)體(ti)較佳
