導讀：在現在水電工程中，開關電源(yuan)是(shi)必不可少的(de)家居用(yong)品，開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)(yuan)漏(lou)(lou)電(dian)(dian)怎么(me)辦，市面上開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)(yuan)產品還是(shi)不少的(de)，功能很(hen)多，品牌也(ye)不少，所以(yi)，選擇的(de)時候也(ye)需要特別(bie)注意。好(hao)的(de)品牌就會避(bi)免漏(lou)(lou)電(dian)(dian)的(de)情況出現，開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)(yuan)漏(lou)(lou)電(dian)(dian)流標準是(shi)多少?下面我(wo)們了(le)解(jie)一些開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)(yuan)故障(zhang)處理(li)，這(zhe)樣我(wo)們就知道開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)(yuan)漏(lou)(lou)電(dian)(dian)怎么(me)辦怎么(me)處理(li)了(le)，往下了(le)解(jie)吧(ba)!

開(kai)關電(dian)源(yuan)漏電(dian)怎么(me)辦
　　開(kai)關(guan)(guan)電(dian)(dian)(dian)源漏(lou)(lou)(lou)電(dian)(dian)(dian)怎么辦，開(kai)關(guan)(guan)電(dian)(dian)(dian)源一(yi)次高(gao)(gao)(gao)壓(ya)通過高(gao)(gao)(gao)頻(pin)(pin)變(bian)壓(ya)器(qi)隔離，輸出端理論上不存在(zai)漏(lou)(lou)(lou)電(dian)(dian)(dian)。但高(gao)(gao)(gao)頻(pin)(pin)開(kai)關(guan)(guan)金(jin)屬(shu)外殼容易感(gan)應電(dian)(dian)(dian)壓(ya)，給人(ren)感(gan)覺是漏(lou)(lou)(lou)電(dian)(dian)(dian)。一(yi)般通過接地消除。開(kai)關(guan)(guan)電(dian)(dian)(dian)源漏(lou)(lou)(lou)電(dian)(dian)(dian)怎么辦，市場上有個別防治開(kai)關(guan)(guan)電(dian)(dian)(dian)源，一(yi)次高(gao)(gao)(gao)壓(ya)部分工藝較差，有些焊點靠貼絕緣紙與金(jin)屬(shu)外殼隔離，非(fei)常危(wei)險(xian)。(AC220V通過低(di)(di)頻(pin)(pin)整流橋、電(dian)(dian)(dian)容濾波成為(wei)DC300V，然后通過高(gao)(gao)(gao)頻(pin)(pin)開(kai)關(guan)(guan)管(guan)、高(gao)(gao)(gao)頻(pin)(pin)隔離變(bian)壓(ya)器(qi)產生交(jiao)變(bian)，高(gao)(gao)(gao)頻(pin)(pin)隔離變(bian)壓(ya)器(qi)二次端感(gan)應出交(jiao)變(bian)低(di)(di)壓(ya)、通過高(gao)(gao)(gao)頻(pin)(pin)整流、濾波成為(wei)低(di)(di)壓(ya)直流電(dian)(dian)(dian)。)

　　開(kai)關電(dian)(dian)源漏電(dian)(dian)怎(zen)么辦，最好外殼接地。或者(zhe)在要求不高(gao)的(de)場合，拆除(chu)與(yu)外殼連(lian)(lian)接的(de)電(dian)(dian)容，高(gao)壓(ya)部分(fen)與(yu)低壓(ya)部分(fen)連(lian)(lian)接的(de)電(dian)(dian)容。

開關(guan)電(dian)源漏(lou)電(dian)流標準

開(kai)(kai)關(guan)電(dian)(dian)(dian)源(yuan)漏(lou)電(dian)(dian)(dian)流(liu)標準，需(xu)要(yao)用耐壓測(ce)試儀(yi)。通過耐壓測(ce)試儀(yi)測(ce)量(liang)的漏(lou)電(dian)(dian)(dian)流(liu)數值，減去開(kai)(kai)關(guan)電(dian)(dian)(dian)源(yuan)對地電(dian)(dian)(dian)容的電(dian)(dian)(dian)流(liu)數值，就是該開(kai)(kai)關(guan)電(dian)(dian)(dian)源(yuan)的漏(lou)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)。或者將開(kai)(kai)關(guan)電(dian)(dian)(dian)源(yuan)對地電(dian)(dian)(dian)容斷開(kai)(kai)，耐壓測(ce)試儀(yi)測(ce)量(liang)的漏(lou)電(dian)(dian)(dian)流(liu)數值就是需(xu)要(yao)測(ce)量(liang)的漏(lou)電(dian)(dian)(dian)流(liu)值。

什么是泄(xie)漏(lou)電流
　　在家用電(dian)器中，泄漏(lou)電(dian)流(liu)是指運(yun)行(xing)的(de)電(dian)氣部分與絕緣之后的(de)金(jin)屬間的(de)安全電(dian)流(liu)。用于220V交(jiao)(jiao)流(liu)電(dian)的(de)電(dian)器之泄漏(lou)電(dian)流(liu)是0.75MA。很微小(xiao)的(de)。交(jiao)(jiao)流(liu)豪(hao)(hao)安表(biao)的(de)一端接在電(dian)源上(shang)(shang)，去掉接地線后，把(ba)交(jiao)(jiao)流(liu)豪(hao)(hao)安表(biao)的(de)另一端接在金(jin)屬間上(shang)(shang)即可。
