電表怎么看？

第一種:一般(ban)的(de)(de)直(zhi)進(jin)式的(de)(de)單相(xiang)電表(biao)和三相(xiang)電表(biao)可直(zhi)接讀取數(shu)字減(jian)去上次的(de)(de)讀數(shu)就為這一階段的(de)(de)電量。直(zhi)進(jin)式的(de)(de)電表(biao)進(jin)線(xian)較粗(cu)，仔細觀(guan)察沒有經過互感器連接。

第二種:三相(xiang)電(dian)(dian)表通(tong)過電(dian)(dian)流(liu)互感(gan)器(qi)連接(jie)(jie)(jie)方式連接(jie)(jie)(jie)的(de)(de)三相(xiang)電(dian)(dian)表，電(dian)(dian)表的(de)(de)接(jie)(jie)(jie)線(xian)有10根接(jie)(jie)(jie)線(xian)，要觀察連接(jie)(jie)(jie)的(de)(de)電(dian)(dian)流(liu)互感(gan)器(qi)的(de)(de)電(dian)(dian)流(liu)比(bi)，電(dian)(dian)流(liu)互感(gan)器(qi)的(de)(de)名(ming)牌上(shang)有，都是一個數字比(bi)5標出的(de)(de)，例(li)如100/5150/5等，電(dian)(dian)表上(shang)讀取的(de)(de)數字乘以(yi)電(dian)(dian)流(liu)比(bi)就(jiu)是計量(liang)的(de)(de)電(dian)(dian)量(liang)，精確的(de)(de)還要加(jia)上(shang)變(bian)損(sun)和線(xian)損(sun)。

第三種:單相電(dian)(dian)(dian)(dian)(dian)表(biao)計量(liang)。單相電(dian)(dian)(dian)(dian)(dian)表(biao)計量(liang)三相電(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)量(liang)，電(dian)(dian)(dian)(dian)(dian)量(liang)讀(du)取方(fang)式是直進式的連(lian)(lian)接(jie)電(dian)(dian)(dian)(dian)(dian)表(biao)的方(fang)式讀(du)取電(dian)(dian)(dian)(dian)(dian)表(biao)上(shang)的數字(zi)乘(cheng)(cheng)以3，若通過互感(gan)器(qi)連(lian)(lian)接(jie)的電(dian)(dian)(dian)(dian)(dian)表(biao)要讀(du)取電(dian)(dian)(dian)(dian)(dian)表(biao)數字(zi)乘(cheng)(cheng)以互感(gan)器(qi)電(dian)(dian)(dian)(dian)(dian)流倍數再(zai)乘(cheng)(cheng)以3。

第四種:智能電(dian)(dian)表(biao)(biao)只(zhi)有一個液晶屏，如(ru)果(guo)是(shi)(shi)單相里面會直(zhi)接顯示總有電(dian)(dian)量和(he)剩(sheng)余(yu)電(dian)(dian)量，直(zhi)接讀(du)數就可以。如(ru)果(guo)是(shi)(shi)IC卡(ka)電(dian)(dian)表(biao)(biao)，只(zhi)有發光(guang)管顯示就是(shi)(shi)單顯卡(ka)表(biao)(biao)。那(nei)(nei)電(dian)(dian)表(biao)(biao)上面上會有個小(xiao)紅點(dian)，紅色(se)的(de)(de)小(xiao)點(dian)跳(tiao)到總用(yong)那(nei)(nei)里就是(shi)(shi)總用(yong)，跳(tiao)到剩(sheng)余(yu)那(nei)(nei)里就是(shi)(shi)剩(sheng)余(yu)。雙顯卡(ka)表(biao)(biao)，讀(du)上面或下(xia)面都可以。三相的(de)(de)預付費電(dian)(dian)表(biao)(biao)直(zhi)入式的(de)(de)直(zhi)接讀(du)數，互感式的(de)(de)用(yong)表(biao)(biao)的(de)(de)讀(du)數乘以互感器(qi)倍率。

最后，要告訴大家的(de)是(shi)，偷電(dian)漏電(dian)是(shi)違法行(xing)為(wei)，是(shi)沒有道(dao)德的(de)表現，提(ti)醒廣(guang)大消(xiao)費者，特別是(shi)喜歡貪小便(bian)宜的(de)人，在(zai)日(ri)常用電(dian)中，應該按時(shi)繳(jiao)納電(dian)費，不偷電(dian)漏電(dian)，看到偷電(dian)漏電(dian)的(de)行(xing)為(wei)，要及(ji)時(shi)舉報，做一(yi)個遵紀守(shou)法的(de)良好市民。
