在大眾的(de)日(ri)常生活中，單(dan)相智(zhi)(zhi)能電(dian)表(biao)扮演著非(fei)常重要的(de)角色(se)，但也(ye)時(shi)常有偷電(dian)的(de)原因(yin)。最近小編經(jing)常看到有人詢問(wen)單(dan)相充控智(zhi)(zhi)能電(dian)表(biao)的(de)防盜原理(li)，那么今天嘉榮華小(xiao)編就為大家(jia)講解(jie)一(yi)下。

根據其功(gong)能和原理，有(you)兩種類型的單相充電(dian)控制智能電(dian)表。

1、被盜(dao)電時，電表(biao)立(li)即斷電，被盜(dao)電后立(li)即恢(hui)復供(gong)電；

2、當電被盜(dao)時，電表會測量(liang)或測量(liang)更快(kuai)。

與(yu)普通電(dian)(dian)(dian)表相比，一(yi)般單(dan)相成(cheng)本控制(zhi)智能電(dian)(dian)(dian)表有一(yi)個控制(zhi)器(qi)(qi)(qi)，由(you)繼電(dian)(dian)(dian)器(qi)(qi)(qi)、變壓(ya)器(qi)(qi)(qi)和電(dian)(dian)(dian)子電(dian)(dian)(dian)路(lu)組(zu)成(cheng)。主電(dian)(dian)(dian)路(lu)的(de)相線(xian)和中(zhong)性線(xian)穿過零序電(dian)(dian)(dian)流互(hu)感器(qi)(qi)(qi)的(de)線(xian)圈。單(dan)相費控智能電(dian)(dian)(dian)表在正常工作時(shi)間內，兩(liang)條線(xian)路(lu)上(shang)的(de)電(dian)(dian)(dian)流相等且相反，變壓(ya)器(qi)(qi)(qi)的(de)感應信(xin)號相互(hu)抵(di)消，輸出信(xin)號為(wei)零。發生偷電(dian)(dian)(dian)時(shi)，進(jin)出電(dian)(dian)(dian)流不同，兩(liang)條線(xian)的(de)電(dian)(dian)(dian)流值也不同。當(dang)超過一(yi)定值時(shi)，會(hui)跳閘并斷電(dian)(dian)(dian)。

另一種是換(huan)計(ji)數(shu)器(qi)，換(huan)成帶換(huan)向輪的(de)(de)雙向繼電(dian)(dian)(dian)(dian)器(qi)。當(dang)有人改變(bian)電(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)壓線圈的(de)(de)極性，采(cai)用(yong)偷(tou)電(dian)(dian)(dian)(dian)等(deng)方法(fa)(fa)將電(dian)(dian)(dian)(dian)能表(biao)的(de)(de)鋁(lv)板倒轉(zhuan)時(shi)單(dan)(dan)相費控智(zhi)能電(dian)(dian)(dian)(dian)表(biao)偷(tou)電(dian)(dian)(dian)(dian)，計(ji)數(shu)器(qi)通過倒轉(zhuan)機構保持(chi)電(dian)(dian)(dian)(dian)能表(biao)的(de)(de)正數(shu)單(dan)(dan)相費控智(zhi)能電(dian)(dian)(dian)(dian)表(biao)偷(tou)電(dian)(dian)(dian)(dian)，用(yong)戶不能用(yong)上(shang)述方法(fa)(fa)使計(ji)數(shu)器(qi)倒計(ji)時(shi)，從而防止偷(tou)電(dian)(dian)(dian)(dian)。
