隨(sui)著國網推動使(shi)用新型智能電表，越來越多(duo)的家庭中電表的外側都會標準5A60A，與之前10A40A的電表不同，5A60A的電表精(jing)度(du)提升(sheng)，那么(me)新電表5A60A與老電表10A40A的區別(bie)是(shi)什么(me)？

新(xin)(xin)電(dian)(dian)(dian)表(biao)(biao)額(e)定電(dian)(dian)(dian)流(liu)(liu)(liu)降低，但(dan)電(dian)(dian)(dian)流(liu)(liu)(liu)提升，可使用到60安培電(dian)(dian)(dian)流(liu)(liu)(liu)，老(lao)(lao)電(dian)(dian)(dian)表(biao)(biao)額(e)定電(dian)(dian)(dian)流(liu)(liu)(liu)大，但(dan)電(dian)(dian)(dian)流(liu)(liu)(liu)小。那么額(e)定電(dian)(dian)(dian)流(liu)(liu)(liu)5A與10A有(you)(you)何區(qu)別呢？主要(yao)是電(dian)(dian)(dian)表(biao)(biao)的起動(dong)電(dian)(dian)(dian)流(liu)(liu)(liu)不同了，起動(dong)電(dian)(dian)(dian)流(liu)(liu)(liu)也就(jiu)是開(kai)(kai)始(shi)記電(dian)(dian)(dian)度數的電(dian)(dian)(dian)流(liu)(liu)(liu)，小于(yu)這個起動(dong)電(dian)(dian)(dian)流(liu)(liu)(liu)是不記電(dian)(dian)(dian)度數的。起動(dong)電(dian)(dian)(dian)流(liu)(liu)(liu)是額(e)定電(dian)(dian)(dian)流(liu)(liu)(liu)的0.004倍，5×0.004=20毫安，相當(dang)于(yu)4.4瓦(wa)，10A表(biao)(biao)剛好(hao)翻倍8.8瓦(wa)。就(jiu)是說(shuo)新(xin)(xin)表(biao)(biao)有(you)(you)4.4瓦(wa)負荷就(jiu)開(kai)(kai)始(shi)記電(dian)(dian)(dian)度數了，而老(lao)(lao)表(biao)(biao)要(yao)達到8.8瓦(wa)才(cai)開(kai)(kai)始(shi)記量(liang)(liang)。電(dian)(dian)(dian)視機、空調(diao)等電(dian)(dian)(dian)器靜(jing)狀(zhuang)功耗(hao)(hao)在3－5瓦(wa)左(zuo)右，以前的老(lao)(lao)表(biao)(biao)是不記量(liang)(liang)的，現在的新(xin)(xin)表(biao)(biao)就(jiu)會(hui)記量(liang)(liang)，以每家靜(jing)態(tai)功耗(hao)(hao)8瓦(wa)算，每月要(yao)耗(hao)(hao)電(dian)(dian)(dian)6度，也就(jiu)是說(shuo)用新(xin)(xin)表(biao)(biao)后每月會(hui)增加(jia)6度電(dian)(dian)(dian)。

因此在不用(yong)空調的季節(jie)要把插頭撥掉，電視(shi)機(ji)關(guan)(guan)機(ji)時也要拔插頭，或(huo)在裝修時在床頭位置(zhi)專門設置(zhi)一個電視(shi)機(ji)開關(guan)(guan)，控制電視(shi)機(ji)插座。
