電表行業簡介

1、直進式電表怎么看

一般的直進(jin)式(shi)(shi)的單相電(dian)表(biao)和三相電(dian)表(biao)可直接(jie)(jie)讀(du)取數字，減(jian)去上次的讀(du)數就為這一階段的電(dian)量(liang)。直進(jin)式(shi)(shi)的電(dian)表(biao)進(jin)線(xian)較(jiao)粗，仔細(xi)觀(guan)察沒有經(jing)過互感(gan)器連(lian)接(jie)(jie)，有互感(gan)器連(lian)接(jie)(jie)的還要乘以相應的倍率。

2、三相電表怎么看

三相電(dian)(dian)(dian)(dian)表通過電(dian)(dian)(dian)(dian)流(liu)(liu)互感(gan)器(qi)連(lian)接(jie)方(fang)式(shi)連(lian)接(jie)，電(dian)(dian)(dian)(dian)表的(de)(de)接(jie)線(xian)有10根，要觀察連(lian)接(jie)的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)互感(gan)器(qi)的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)比。電(dian)(dian)(dian)(dian)流(liu)(liu)互感(gan)器(qi)的(de)(de)銘牌上有電(dian)(dian)(dian)(dian)流(liu)(liu)比，都是一個數(shu)字比5標出的(de)(de)，例如100/5、150/5等，電(dian)(dian)(dian)(dian)表上讀取(qu)的(de)(de)數(shu)字乘以(yi)電(dian)(dian)(dian)(dian)流(liu)(liu)比就是計量的(de)(de)電(dian)(dian)(dian)(dian)量，精確的(de)(de)還要加上變損和線(xian)損。

3、單相電表怎么看

單相電表計量三相電的電量，電量讀取方式是直進式的連接電表的方式，讀取電表上的數字乘以3，若通過互感器連接的電表，要讀取電表數字乘以互感器電流倍數再乘以3，這種電表品牌產品讀法比較簡單。

4、智能電表怎么看

智能電(dian)(dian)(dian)(dian)表(biao)(biao)只(zhi)有(you)一個(ge)液晶(jing)屏，如(ru)(ru)果是(shi)單相里(li)面會直(zhi)接(jie)顯(xian)(xian)(xian)示總(zong)有(you)電(dian)(dian)(dian)(dian)量和剩余電(dian)(dian)(dian)(dian)量，直(zhi)接(jie)讀數就可(ke)以。如(ru)(ru)果是(shi)IC卡電(dian)(dian)(dian)(dian)表(biao)(biao)，只(zhi)有(you)發光管(guan)顯(xian)(xian)(xian)示就是(shi)單顯(xian)(xian)(xian)卡表(biao)(biao)，那(nei)(nei)電(dian)(dian)(dian)(dian)表(biao)(biao)上(shang)面上(shang)會有(you)個(ge)小紅點。紅色的(de)小點跳(tiao)到(dao)總(zong)用那(nei)(nei)里(li)就是(shi)總(zong)用，跳(tiao)到(dao)剩余那(nei)(nei)里(li)就是(shi)剩余。雙顯(xian)(xian)(xian)卡表(biao)(biao)，讀上(shang)面或(huo)下面都可(ke)以。三相的(de)預付費(fei)電(dian)(dian)(dian)(dian)表(biao)(biao)直(zhi)入(ru)式的(de)直(zhi)接(jie)讀數，互感式的(de)用表(biao)(biao)的(de)讀數乘以互感器倍率(lv)。

5、電表顯示跳閘怎么辦

空氣(qi)(qi)開關(guan)出現老(lao)化的(de)(de)問題，內(nei)部(bu)電(dian)磁脫扣不能(neng)(neng)很好的(de)(de)鎖(suo)扣。經常性出現脫扣問題，不存在修復的(de)(de)可(ke)能(neng)(neng)，只能(neng)(neng)直接換掉，或(huo)讓當地(di)供電(dian)部(bu)門進行(xing)處(chu)理(li)。空氣(qi)(qi)開關(guan)接線(xian)柱接觸不良導致發熱(re)，熱(re)量(liang)傳遞(di)到空開上，空開有過載跳閘(zha)功能(neng)(neng)也叫熱(re)脫扣，會出現跳閘(zha)。空氣(qi)(qi)開關(guan)上都會標(biao)有額定(ding)電(dian)流數(shu)，比如(ru)C32是(shi)指家用最大(da)功率不能(neng)(neng)超(chao)過7000W，如(ru)果超(chao)過就會引(yin)起跳閘(zha)。
