開關電(dian)源(yuan)漏電(dian)怎么辦
　　開關電(dian)(dian)(dian)(dian)源(yuan)漏電(dian)(dian)(dian)(dian)怎(zen)么(me)辦，開關電(dian)(dian)(dian)(dian)源(yuan)一(yi)次(ci)高(gao)(gao)壓通過高(gao)(gao)頻(pin)(pin)(pin)變(bian)壓器(qi)(qi)(qi)隔(ge)離，輸出端理論上(shang)不存(cun)在(zai)漏電(dian)(dian)(dian)(dian)。但(dan)高(gao)(gao)頻(pin)(pin)(pin)開關金(jin)屬外殼(ke)容(rong)易感(gan)應(ying)電(dian)(dian)(dian)(dian)壓，給人感(gan)覺是漏電(dian)(dian)(dian)(dian)。一(yi)般通過接地消除。開關電(dian)(dian)(dian)(dian)源(yuan)漏電(dian)(dian)(dian)(dian)怎(zen)么(me)辦，市場(chang)上(shang)有個別防治開關電(dian)(dian)(dian)(dian)源(yuan)，一(yi)次(ci)高(gao)(gao)壓部分工(gong)藝較差，有些焊點靠貼(tie)絕(jue)緣紙(zhi)與(yu)金(jin)屬外殼(ke)隔(ge)離，非常危險。(AC220V通過低(di)(di)頻(pin)(pin)(pin)整流(liu)橋、電(dian)(dian)(dian)(dian)容(rong)濾波(bo)成(cheng)為DC300V，然后通過高(gao)(gao)頻(pin)(pin)(pin)開關管、高(gao)(gao)頻(pin)(pin)(pin)隔(ge)離變(bian)壓器(qi)(qi)(qi)產(chan)生交(jiao)變(bian)，高(gao)(gao)頻(pin)(pin)(pin)隔(ge)離變(bian)壓器(qi)(qi)(qi)二(er)次(ci)端感(gan)應(ying)出交(jiao)變(bian)低(di)(di)壓、通過高(gao)(gao)頻(pin)(pin)(pin)整流(liu)、濾波(bo)成(cheng)為低(di)(di)壓直流(liu)電(dian)(dian)(dian)(dian)。)

　　開關(guan)電(dian)源漏電(dian)怎么(me)辦，最好(hao)外殼(ke)接地。或者在要求不高的場(chang)合，拆除與外殼(ke)連接的電(dian)容，高壓(ya)部分與低壓(ya)部分連接的電(dian)容。

開關電源漏電流標準

開(kai)關電(dian)(dian)(dian)源(yuan)漏(lou)電(dian)(dian)(dian)流(liu)標準，需(xu)要(yao)(yao)用耐(nai)壓(ya)測(ce)(ce)試(shi)(shi)儀(yi)。通過耐(nai)壓(ya)測(ce)(ce)試(shi)(shi)儀(yi)測(ce)(ce)量(liang)的漏(lou)電(dian)(dian)(dian)流(liu)數值(zhi)(zhi)，減去開(kai)關電(dian)(dian)(dian)源(yuan)對地(di)電(dian)(dian)(dian)容的電(dian)(dian)(dian)流(liu)數值(zhi)(zhi)，就(jiu)是(shi)該開(kai)關電(dian)(dian)(dian)源(yuan)的漏(lou)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)。或者(zhe)將開(kai)關電(dian)(dian)(dian)源(yuan)對地(di)電(dian)(dian)(dian)容斷開(kai)，耐(nai)壓(ya)測(ce)(ce)試(shi)(shi)儀(yi)測(ce)(ce)量(liang)的漏(lou)電(dian)(dian)(dian)流(liu)數值(zhi)(zhi)就(jiu)是(shi)需(xu)要(yao)(yao)測(ce)(ce)量(liang)的漏(lou)電(dian)(dian)(dian)流(liu)值(zhi)(zhi)。

什么是泄漏(lou)電流
　　在家(jia)用電(dian)(dian)器(qi)中，泄(xie)漏電(dian)(dian)流(liu)(liu)是(shi)指運(yun)行的(de)電(dian)(dian)氣部分與(yu)絕緣之(zhi)后(hou)的(de)金(jin)屬間的(de)安全(quan)電(dian)(dian)流(liu)(liu)。用于220V交流(liu)(liu)電(dian)(dian)的(de)電(dian)(dian)器(qi)之(zhi)泄(xie)漏電(dian)(dian)流(liu)(liu)是(shi)0.75MA。很微小的(de)。交流(liu)(liu)豪安表的(de)一(yi)端接在電(dian)(dian)源上，去掉接地線后(hou)，把交流(liu)(liu)豪安表的(de)另一(yi)端接在金(jin)屬間上即可。
