電表怎么看?
第一種:一般的(de)直(zhi)進式的(de)單相電(dian)表(biao)和三相電(dian)表(biao)可直(zhi)接讀(du)(du)取數字減去上次(ci)的(de)讀(du)(du)數就為這一階段(duan)的(de)電(dian)量(liang)。直(zhi)進式的(de)電(dian)表(biao)進線較粗,仔細(xi)觀察沒(mei)有經(jing)過互感器連接。
第二種:三相(xiang)電(dian)(dian)表通(tong)過(guo)電(dian)(dian)流互(hu)感(gan)器(qi)連(lian)(lian)接方式連(lian)(lian)接的(de)(de)(de)三相(xiang)電(dian)(dian)表,電(dian)(dian)表的(de)(de)(de)接線有(you)10根接線,要(yao)觀察(cha)連(lian)(lian)接的(de)(de)(de)電(dian)(dian)流互(hu)感(gan)器(qi)的(de)(de)(de)電(dian)(dian)流比(bi),電(dian)(dian)流互(hu)感(gan)器(qi)的(de)(de)(de)名牌上有(you),都是一個數(shu)字(zi)比(bi)5標出的(de)(de)(de),例如(ru)100/5150/5等,電(dian)(dian)表上讀(du)取的(de)(de)(de)數(shu)字(zi)乘以電(dian)(dian)流比(bi)就是計(ji)量的(de)(de)(de)電(dian)(dian)量,精確(que)的(de)(de)(de)還(huan)要(yao)加上變損(sun)和線損(sun)。
第三種:單相電(dian)(dian)(dian)表計量。單相電(dian)(dian)(dian)表計量三相電(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)量,電(dian)(dian)(dian)量讀取方(fang)式(shi)(shi)是直進式(shi)(shi)的(de)(de)(de)連(lian)接電(dian)(dian)(dian)表的(de)(de)(de)方(fang)式(shi)(shi)讀取電(dian)(dian)(dian)表上的(de)(de)(de)數(shu)字乘(cheng)以(yi)3,若通過互(hu)感器連(lian)接的(de)(de)(de)電(dian)(dian)(dian)表要(yao)讀取電(dian)(dian)(dian)表數(shu)字乘(cheng)以(yi)互(hu)感器電(dian)(dian)(dian)流(liu)倍數(shu)再(zai)乘(cheng)以(yi)3。
第四種:智能電(dian)(dian)(dian)表只(zhi)(zhi)有(you)一個液晶屏,如果是(shi)單(dan)相(xiang)里(li)面會直(zhi)接(jie)顯(xian)示總(zong)(zong)有(you)電(dian)(dian)(dian)量(liang)和(he)剩余(yu)電(dian)(dian)(dian)量(liang),直(zhi)接(jie)讀(du)數(shu)(shu)就可以(yi)(yi)。如果是(shi)IC卡電(dian)(dian)(dian)表,只(zhi)(zhi)有(you)發(fa)光管顯(xian)示就是(shi)單(dan)顯(xian)卡表。那電(dian)(dian)(dian)表上面上會有(you)個小紅點,紅色的(de)小點跳到總(zong)(zong)用那里(li)就是(shi)總(zong)(zong)用,跳到剩余(yu)那里(li)就是(shi)剩余(yu)。雙顯(xian)卡表,讀(du)上面或下面都可以(yi)(yi)。三相(xiang)的(de)預付(fu)費電(dian)(dian)(dian)表直(zhi)入(ru)式(shi)(shi)的(de)直(zhi)接(jie)讀(du)數(shu)(shu),互感式(shi)(shi)的(de)用表的(de)讀(du)數(shu)(shu)乘以(yi)(yi)互感器倍(bei)率(lv)。
最后,要告訴大家的(de)(de)(de)是,偷電(dian)(dian)漏電(dian)(dian)是違(wei)法(fa)行為,是沒有道(dao)德的(de)(de)(de)表現(xian),提醒(xing)廣大消費者,特別是喜歡貪小便(bian)宜的(de)(de)(de)人,在日常用電(dian)(dian)中(zhong),應該按時(shi)繳納電(dian)(dian)費,不(bu)偷電(dian)(dian)漏電(dian)(dian),看到偷電(dian)(dian)漏電(dian)(dian)的(de)(de)(de)行為,要及時(shi)舉報(bao),做一個遵紀守(shou)法(fa)的(de)(de)(de)良(liang)好市(shi)民。
選購電表時千萬不要(yao)因為(wei)價(jia)格(ge)便宜,而盲目跟從購買,選擇比較有知(zhi)名度(du)的(de)品牌,不僅品質有保證,售(shou)后服務(wu)也有保障。當然追求(qiu)品牌的(de)東西不一(yi)定就是追求(qiu)價(jia)格(ge)的(de)昂(ang)貴,不同的(de)經濟水平我們可以選擇不同價(jia)位的(de)名牌產品。選擇網購商品的(de)朋友要(yao)認準品牌的(de)旗(qi)艦店鋪(pu),這(zhe)樣(yang)子(zi)才(cai)能做到萬無(wu)一(yi)失(shi)。
