1、直進式電表怎么看
一般的(de)直(zhi)進式(shi)的(de)單相電表和(he)三相電表可直(zhi)接讀取(qu)數字,減去上次的(de)讀數就為這(zhe)一階段的(de)電量。直(zhi)進式(shi)的(de)電表進線較粗,仔細觀察沒有經過互感器連(lian)接,有互感器連(lian)接的(de)還要(yao)乘以相應的(de)倍率。
2、三相電表怎么看
三(san)相電(dian)(dian)(dian)(dian)表(biao)通過電(dian)(dian)(dian)(dian)流(liu)互感器連(lian)接方式連(lian)接,電(dian)(dian)(dian)(dian)表(biao)的(de)(de)接線有10根,要(yao)觀(guan)察連(lian)接的(de)(de)電(dian)(dian)(dian)(dian)流(liu)互感器的(de)(de)電(dian)(dian)(dian)(dian)流(liu)比(bi)。電(dian)(dian)(dian)(dian)流(liu)互感器的(de)(de)銘牌上(shang)有電(dian)(dian)(dian)(dian)流(liu)比(bi),都是一(yi)個數(shu)字比(bi)5標出的(de)(de),例(li)如100/5、150/5等,電(dian)(dian)(dian)(dian)表(biao)上(shang)讀取(qu)的(de)(de)數(shu)字乘以電(dian)(dian)(dian)(dian)流(liu)比(bi)就是計量的(de)(de)電(dian)(dian)(dian)(dian)量,精確的(de)(de)還要(yao)加上(shang)變損(sun)和線損(sun)。
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)表(biao)只有(you)一個液晶屏,如(ru)(ru)果是(shi)(shi)單(dan)相里面(mian)會直接(jie)(jie)顯(xian)示總(zong)(zong)有(you)電(dian)量和剩(sheng)(sheng)余電(dian)量,直接(jie)(jie)讀(du)數(shu)就可(ke)以(yi)。如(ru)(ru)果是(shi)(shi)IC卡電(dian)表(biao),只有(you)發光(guang)管顯(xian)示就是(shi)(shi)單(dan)顯(xian)卡表(biao),那(nei)電(dian)表(biao)上(shang)面(mian)上(shang)會有(you)個小(xiao)紅(hong)點(dian)。紅(hong)色的(de)(de)小(xiao)點(dian)跳(tiao)到總(zong)(zong)用那(nei)里就是(shi)(shi)總(zong)(zong)用,跳(tiao)到剩(sheng)(sheng)余那(nei)里就是(shi)(shi)剩(sheng)(sheng)余。雙顯(xian)卡表(biao),讀(du)上(shang)面(mian)或下面(mian)都可(ke)以(yi)。三相的(de)(de)預付費(fei)電(dian)表(biao)直入式(shi)的(de)(de)直接(jie)(jie)讀(du)數(shu),互感式(shi)的(de)(de)用表(biao)的(de)(de)讀(du)數(shu)乘以(yi)互感器倍率。
5、電表顯示跳閘怎么辦
空(kong)氣(qi)開關出現(xian)老化(hua)的問題,內部(bu)電磁脫扣(kou)不能(neng)很好的鎖扣(kou)。經常性出現(xian)脫扣(kou)問題,不存在修復的可能(neng),只(zhi)能(neng)直接(jie)換掉,或讓當地供電部(bu)門進行處理。空(kong)氣(qi)開關接(jie)線(xian)柱接(jie)觸不良導致(zhi)發熱,熱量傳遞到(dao)空(kong)開上,空(kong)開有過載跳閘(zha)功能(neng)也叫熱脫扣(kou),會(hui)(hui)出現(xian)跳閘(zha)。空(kong)氣(qi)開關上都會(hui)(hui)標有額(e)定電流(liu)數(shu),比如(ru)C32是指家用(yong)最大(da)功率不能(neng)超過7000W,如(ru)果超過就會(hui)(hui)引起跳閘(zha)。
