導讀(du)：在現在水電工程中，開關電源是(shi)必(bi)不(bu)可少的家居(ju)用品，開(kai)關(guan)電(dian)(dian)(dian)(dian)源漏電(dian)(dian)(dian)(dian)怎(zen)么辦(ban)，市(shi)面(mian)上開(kai)關(guan)電(dian)(dian)(dian)(dian)源產品還(huan)是(shi)不(bu)少的，功能很(hen)多(duo)(duo)，品牌(pai)(pai)也不(bu)少，所以，選擇的時候(hou)也需要特別注意。好(hao)的品牌(pai)(pai)就(jiu)會避(bi)免漏電(dian)(dian)(dian)(dian)的情況出現，開(kai)關(guan)電(dian)(dian)(dian)(dian)源漏電(dian)(dian)(dian)(dian)流(liu)標準是(shi)多(duo)(duo)少?下面(mian)我(wo)們(men)了解(jie)(jie)一些開(kai)關(guan)電(dian)(dian)(dian)(dian)源故障(zhang)處(chu)理(li)，這樣我(wo)們(men)就(jiu)知道開(kai)關(guan)電(dian)(dian)(dian)(dian)源漏電(dian)(dian)(dian)(dian)怎(zen)么辦(ban)怎(zen)么處(chu)理(li)了，往下了解(jie)(jie)吧!

開關電源漏(lou)電怎(zen)么辦(ban)
　　開(kai)(kai)(kai)關(guan)電(dian)源漏電(dian)怎(zen)么(me)辦，開(kai)(kai)(kai)關(guan)電(dian)源一(yi)(yi)次(ci)(ci)高(gao)壓(ya)通過(guo)(guo)高(gao)頻(pin)變(bian)壓(ya)器(qi)(qi)隔(ge)離，輸(shu)出(chu)端(duan)理論上不(bu)存在漏電(dian)。但高(gao)頻(pin)開(kai)(kai)(kai)關(guan)金屬外(wai)殼(ke)容易(yi)感(gan)應電(dian)壓(ya)，給人感(gan)覺是漏電(dian)。一(yi)(yi)般通過(guo)(guo)接地消除。開(kai)(kai)(kai)關(guan)電(dian)源漏電(dian)怎(zen)么(me)辦，市場上有個(ge)別防治開(kai)(kai)(kai)關(guan)電(dian)源，一(yi)(yi)次(ci)(ci)高(gao)壓(ya)部分工(gong)藝較差(cha)，有些焊點靠貼絕緣紙與(yu)金屬外(wai)殼(ke)隔(ge)離，非常危險。(AC220V通過(guo)(guo)低頻(pin)整(zheng)流(liu)橋、電(dian)容濾波(bo)成(cheng)(cheng)為DC300V，然后(hou)通過(guo)(guo)高(gao)頻(pin)開(kai)(kai)(kai)關(guan)管、高(gao)頻(pin)隔(ge)離變(bian)壓(ya)器(qi)(qi)產生交(jiao)變(bian)，高(gao)頻(pin)隔(ge)離變(bian)壓(ya)器(qi)(qi)二(er)次(ci)(ci)端(duan)感(gan)應出(chu)交(jiao)變(bian)低壓(ya)、通過(guo)(guo)高(gao)頻(pin)整(zheng)流(liu)、濾波(bo)成(cheng)(cheng)為低壓(ya)直流(liu)電(dian)。)

　　開關電源漏電怎么(me)辦，最(zui)好外殼接地。或(huo)者在(zai)要求不高的(de)場合，拆除與外殼連接的(de)電容(rong)，高壓部(bu)分與低壓部(bu)分連接的(de)電容(rong)。

開關電源漏電流標準

開(kai)關電(dian)(dian)(dian)源漏電(dian)(dian)(dian)流(liu)(liu)標準，需要(yao)用耐(nai)(nai)壓測試(shi)儀。通過耐(nai)(nai)壓測試(shi)儀測量的(de)(de)漏電(dian)(dian)(dian)流(liu)(liu)數(shu)(shu)值，減去(qu)開(kai)關電(dian)(dian)(dian)源對地電(dian)(dian)(dian)容(rong)的(de)(de)電(dian)(dian)(dian)流(liu)(liu)數(shu)(shu)值，就是該開(kai)關電(dian)(dian)(dian)源的(de)(de)漏電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)。或者將開(kai)關電(dian)(dian)(dian)源對地電(dian)(dian)(dian)容(rong)斷開(kai)，耐(nai)(nai)壓測試(shi)儀測量的(de)(de)漏電(dian)(dian)(dian)流(liu)(liu)數(shu)(shu)值就是需要(yao)測量的(de)(de)漏電(dian)(dian)(dian)流(liu)(liu)值。

什么(me)是泄漏電流(liu)
　　在家用(yong)(yong)電器中，泄漏電流是(shi)指運行(xing)的(de)電氣部分與絕緣(yuan)之后(hou)(hou)的(de)金屬(shu)間的(de)安(an)全(quan)電流。用(yong)(yong)于220V交(jiao)流電的(de)電器之泄漏電流是(shi)0.75MA。很(hen)微小的(de)。交(jiao)流豪安(an)表(biao)的(de)一(yi)端接在電源(yuan)上(shang)(shang)，去掉接地線后(hou)(hou)，把交(jiao)流豪安(an)表(biao)的(de)另一(yi)端接在金屬(shu)間上(shang)(shang)即可。
