導讀:在(zai)現(xian)在(zai)水電工程中,開關電源(yuan)是必(bi)不可少的(de)家居用品(pin),開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)漏(lou)電(dian)(dian)怎么(me)(me)辦,市面上開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)產品(pin)還是不少的(de),功能很多,品(pin)牌也不少,所以,選擇(ze)的(de)時候(hou)也需要特別注意。好的(de)品(pin)牌就會避免(mian)漏(lou)電(dian)(dian)的(de)情(qing)況(kuang)出現,開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)漏(lou)電(dian)(dian)流標準是多少?下面我(wo)們了解(jie)一些開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)故障處(chu)理,這樣我(wo)們就知道開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)漏(lou)電(dian)(dian)怎么(me)(me)辦怎么(me)(me)處(chu)理了,往下了解(jie)吧!


開(kai)關電(dian)源漏電(dian)怎(zen)么辦
  開(kai)(kai)關(guan)電(dian)(dian)(dian)源(yuan)漏電(dian)(dian)(dian)怎(zen)么辦,開(kai)(kai)關(guan)電(dian)(dian)(dian)源(yuan)一(yi)次(ci)高(gao)壓(ya)(ya)通(tong)(tong)過高(gao)頻(pin)(pin)(pin)變壓(ya)(ya)器隔(ge)離,輸出端理論上(shang)不存在漏電(dian)(dian)(dian)。但高(gao)頻(pin)(pin)(pin)開(kai)(kai)關(guan)金(jin)屬外殼(ke)容(rong)易感(gan)應電(dian)(dian)(dian)壓(ya)(ya),給人感(gan)覺是漏電(dian)(dian)(dian)。一(yi)般(ban)通(tong)(tong)過接地消除。開(kai)(kai)關(guan)電(dian)(dian)(dian)源(yuan)漏電(dian)(dian)(dian)怎(zen)么辦,市(shi)場上(shang)有個別防治開(kai)(kai)關(guan)電(dian)(dian)(dian)源(yuan),一(yi)次(ci)高(gao)壓(ya)(ya)部分(fen)工藝(yi)較差,有些焊點靠(kao)貼絕緣(yuan)紙與(yu)金(jin)屬外殼(ke)隔(ge)離,非(fei)常危險。(AC220V通(tong)(tong)過低(di)頻(pin)(pin)(pin)整流(liu)橋、電(dian)(dian)(dian)容(rong)濾波成(cheng)為DC300V,然后(hou)通(tong)(tong)過高(gao)頻(pin)(pin)(pin)開(kai)(kai)關(guan)管、高(gao)頻(pin)(pin)(pin)隔(ge)離變壓(ya)(ya)器產生(sheng)交變,高(gao)頻(pin)(pin)(pin)隔(ge)離變壓(ya)(ya)器二次(ci)端感(gan)應出交變低(di)壓(ya)(ya)、通(tong)(tong)過高(gao)頻(pin)(pin)(pin)整流(liu)、濾波成(cheng)為低(di)壓(ya)(ya)直(zhi)流(liu)電(dian)(dian)(dian)。)

  開(kai)關電(dian)(dian)源漏(lou)電(dian)(dian)怎么辦,最好外(wai)殼接地(di)。或者在要(yao)求不高的場合,拆(chai)除(chu)與(yu)外(wai)殼連接的電(dian)(dian)容,高壓部(bu)分(fen)與(yu)低壓部(bu)分(fen)連接的電(dian)(dian)容。

開關電源漏電流標準

開關電(dian)(dian)(dian)(dian)源(yuan)漏電(dian)(dian)(dian)(dian)流(liu)標準(zhun),需要用耐壓測(ce)試(shi)儀。通過耐壓測(ce)試(shi)儀測(ce)量的漏電(dian)(dian)(dian)(dian)流(liu)數(shu)(shu)值,減去開關電(dian)(dian)(dian)(dian)源(yuan)對地(di)電(dian)(dian)(dian)(dian)容的電(dian)(dian)(dian)(dian)流(liu)數(shu)(shu)值,就(jiu)是該開關電(dian)(dian)(dian)(dian)源(yuan)的漏電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)。或者將開關電(dian)(dian)(dian)(dian)源(yuan)對地(di)電(dian)(dian)(dian)(dian)容斷(duan)開,耐壓測(ce)試(shi)儀測(ce)量的漏電(dian)(dian)(dian)(dian)流(liu)數(shu)(shu)值就(jiu)是需要測(ce)量的漏電(dian)(dian)(dian)(dian)流(liu)值。

什么是泄漏電流
  在(zai)(zai)家用電(dian)器中,泄漏(lou)電(dian)流是(shi)指運行的(de)電(dian)氣部分與絕緣(yuan)之后(hou)的(de)金(jin)屬間(jian)的(de)安全電(dian)流。用于220V交(jiao)(jiao)流電(dian)的(de)電(dian)器之泄漏(lou)電(dian)流是(shi)0.75MA。很微小的(de)。交(jiao)(jiao)流豪(hao)安表(biao)(biao)的(de)一端(duan)(duan)接(jie)在(zai)(zai)電(dian)源上,去掉(diao)接(jie)地線(xian)后(hou),把交(jiao)(jiao)流豪(hao)安表(biao)(biao)的(de)另一端(duan)(duan)接(jie)在(zai)(zai)金(jin)屬間(jian)上即可。
