導讀：在現在水(shui)電工程中，開關電(dian)源是必不可少(shao)的家(jia)居用品(pin)，開(kai)關電(dian)(dian)(dian)(dian)源(yuan)(yuan)漏(lou)電(dian)(dian)(dian)(dian)怎(zen)么辦，市(shi)面上開(kai)關電(dian)(dian)(dian)(dian)源(yuan)(yuan)產品(pin)還(huan)是不少(shao)的，功能很(hen)多(duo)(duo)，品(pin)牌也不少(shao)，所以，選擇的時候(hou)也需要(yao)特別注意。好的品(pin)牌就會避免漏(lou)電(dian)(dian)(dian)(dian)的情(qing)況(kuang)出現，開(kai)關電(dian)(dian)(dian)(dian)源(yuan)(yuan)漏(lou)電(dian)(dian)(dian)(dian)流(liu)標準是多(duo)(duo)少(shao)?下面我們了(le)解(jie)一些開(kai)關電(dian)(dian)(dian)(dian)源(yuan)(yuan)故障處(chu)理，這(zhe)樣我們就知道開(kai)關電(dian)(dian)(dian)(dian)源(yuan)(yuan)漏(lou)電(dian)(dian)(dian)(dian)怎(zen)么辦怎(zen)么處(chu)理了(le)，往(wang)下了(le)解(jie)吧(ba)!

開關電(dian)源漏電(dian)怎么辦
　　開(kai)(kai)(kai)關電(dian)(dian)(dian)(dian)源(yuan)漏(lou)電(dian)(dian)(dian)(dian)怎么辦，開(kai)(kai)(kai)關電(dian)(dian)(dian)(dian)源(yuan)一(yi)次高壓(ya)(ya)(ya)通(tong)過(guo)高頻(pin)變(bian)(bian)壓(ya)(ya)(ya)器隔(ge)離，輸出(chu)端理(li)論(lun)上不存在漏(lou)電(dian)(dian)(dian)(dian)。但高頻(pin)開(kai)(kai)(kai)關金屬(shu)(shu)外殼容易感應電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，給(gei)人感覺是漏(lou)電(dian)(dian)(dian)(dian)。一(yi)般通(tong)過(guo)接地消(xiao)除。開(kai)(kai)(kai)關電(dian)(dian)(dian)(dian)源(yuan)漏(lou)電(dian)(dian)(dian)(dian)怎么辦，市場上有個(ge)別防治開(kai)(kai)(kai)關電(dian)(dian)(dian)(dian)源(yuan)，一(yi)次高壓(ya)(ya)(ya)部(bu)分工藝較(jiao)差，有些焊點靠貼絕緣紙(zhi)與金屬(shu)(shu)外殼隔(ge)離，非常危險。(AC220V通(tong)過(guo)低(di)頻(pin)整流(liu)(liu)橋、電(dian)(dian)(dian)(dian)容濾波成為DC300V，然(ran)后(hou)通(tong)過(guo)高頻(pin)開(kai)(kai)(kai)關管、高頻(pin)隔(ge)離變(bian)(bian)壓(ya)(ya)(ya)器產生交變(bian)(bian)，高頻(pin)隔(ge)離變(bian)(bian)壓(ya)(ya)(ya)器二(er)次端感應出(chu)交變(bian)(bian)低(di)壓(ya)(ya)(ya)、通(tong)過(guo)高頻(pin)整流(liu)(liu)、濾波成為低(di)壓(ya)(ya)(ya)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)。)

　　開關(guan)電源漏電怎(zen)么(me)辦，最好外殼接(jie)地。或者在要求不高的(de)場合(he)，拆除(chu)與外殼連接(jie)的(de)電容，高壓部分與低壓部分連接(jie)的(de)電容。

開關(guan)電源漏電流標準

開關(guan)電(dian)(dian)源漏電(dian)(dian)流(liu)(liu)標準，需(xu)要用耐(nai)壓測(ce)試儀。通過耐(nai)壓測(ce)試儀測(ce)量(liang)的漏電(dian)(dian)流(liu)(liu)數值(zhi)(zhi)，減去開關(guan)電(dian)(dian)源對地電(dian)(dian)容的電(dian)(dian)流(liu)(liu)數值(zhi)(zhi)，就(jiu)是該開關(guan)電(dian)(dian)源的漏電(dian)(dian)電(dian)(dian)流(liu)(liu)。或者將(jiang)開關(guan)電(dian)(dian)源對地電(dian)(dian)容斷(duan)開，耐(nai)壓測(ce)試儀測(ce)量(liang)的漏電(dian)(dian)流(liu)(liu)數值(zhi)(zhi)就(jiu)是需(xu)要測(ce)量(liang)的漏電(dian)(dian)流(liu)(liu)值(zhi)(zhi)。

什么是泄漏電流
　　在家用電(dian)器(qi)中，泄漏電(dian)流是指運行的(de)(de)電(dian)氣部分與絕緣之(zhi)后的(de)(de)金屬間(jian)的(de)(de)安(an)全電(dian)流。用于220V交流電(dian)的(de)(de)電(dian)器(qi)之(zhi)泄漏電(dian)流是0.75MA。很(hen)微小的(de)(de)。交流豪安(an)表的(de)(de)一端接在電(dian)源上，去掉接地線后，把交流豪安(an)表的(de)(de)另一端接在金屬間(jian)上即可。
