智能电(dian)(dian)(dian)(dian)(dian)(dian)(dian)表的主要(yao)类型有IC卡(ka)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)表，用(yong)户持IC卡(ka)到供电(dian)(dian)(dian)(dian)(dian)(dian)(dian)部门交款购电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，供电(dian)(dian)(dian)(dian)(dian)(dian)(dian)部门用(yong)售电(dian)(dian)(dian)(dian)(dian)(dian)(dian)管理机将购电(dian)(dian)(dian)(dian)(dian)(dian)(dian)量写入IC卡(ka)中，用(yong)户持IC卡(ka)在感(gan)应区(qu)刷非接(jie)触式(shi)IC卡(ka)(简称刷卡(ka)，下同)，即可(ke)合闸(zha)供电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，供电(dian)(dian)(dian)(dian)(dian)(dian)(dian)后将卡(ka)拿(na)走。当(dang)表内剩余电(dian)(dian)(dian)(dian)(dian)(dian)(dian)量等于(yu)报警电(dian)(dian)(dian)(dian)(dian)(dian)(dian)量时，拉(la)闸(zha)断电(dian)(dian)(dian)(dian)(dian)(dian)(dian)报警(或蜂鸣器(qi)报警)，此时用(yong)户在感(gan)应区(qu)刷卡(ka)即可(ke)恢复供电(dian)(dian)(dian)(dian)(dian)(dian)(dian);当(dang)剩余电(dian)(dian)(dian)(dian)(dian)(dian)(dian)量为零时，自动拉(la)闸(zha)断电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，用(yong)户必须(xu)再次持卡(ka)交费购电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，才(cai)可(ke)以恢复用(yong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)。对于(yu)居民用(yong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，在与(yu)机械式(shi)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)表、电(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)式(shi)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)表作对比时，它有以下几(ji)点的优势：

三相四线怎么接？

首先你得明白什么(me)是三(san)(san)相(xiang)四线(xian)(xian)(xian)制供电(dian)(dian)电(dian)(dian)路：三(san)(san)相(xiang)四线(xian)(xian)(xian)制指三(san)(san)相(xiang)交流(liu)(liu)供电(dian)(dian)中有三(san)(san)根(gen)火线(xian)(xian)(xian)（U、V、W表(biao)示），一根(gen)零线(xian)(xian)(xian)（N表(biao)示）。每两条火线(xian)(xian)(xian)之间电(dian)(dian)压(ya)(ya)(ya)380V，称(cheng)为线(xian)(xian)(xian)电(dian)(dian)压(ya)(ya)(ya)，任何一根(gen)火线(xian)(xian)(xian)与(yu)零线(xian)(xian)(xian)的(de)电(dian)(dian)压(ya)(ya)(ya)为220V，称(cheng)为相(xiang)电(dian)(dian)压(ya)(ya)(ya)。所以，220V的(de)灯泡不管功率多少，都应给(ji)接(jie)相(xiang)电(dian)(dian)压(ya)(ya)(ya)，即一根(gen)接(jie)零线(xian)(xian)(xian)，另一根(gen)任接(jie)一根(gen)火线(xian)(xian)(xian)。按三(san)(san)相(xiang)交流(liu)(liu)电(dian)(dian)压(ya)(ya)(ya)380V考虑，线(xian)(xian)(xian)电(dian)(dian)压(ya)(ya)(ya)为380V，相(xiang)电(dian)(dian)压(ya)(ya)(ya)为220V，则三(san)(san)只相(xiang)同阻抗元件，先以星(xing)形接(jie)入，再以角形接(jie)入，其中Z为电(dian)(dian)机每相(xiang)绕组的(de)阻抗（三(san)(san)根(gen)钨丝管），应该是相(xiang)电(dian)(dian)流(liu)(liu)会增大(da)到原来(lai)的(de)1.732（根(gen)号3）倍(bei)(bei)，线(xian)(xian)(xian)电(dian)(dian)流(liu)(liu)会增大(da)到原来(lai)的(de)3倍(bei)(bei)，功率也变为原来(lai)的(de)3倍(bei)(bei)。

三相四线怎么接？

三相四线中，零线的作用是：

1、在三(san)项负载不平(ping)衡(heng)的(de)情况下，零线(xian)导(dao)通，不平(ping)衡(heng)电流流回中性点，从而使(shi)供电系(xi)统(tong)的(de)线(xian)电压(ya)、相电压(ya)基本保(bao)持平(ping)衡(heng)；

2、当(dang)采用保护接零(ling)(ling)的电(dian)气设备绝缘损坏发(fa)生碰壳(qiao)时(shi)，短路(lu)电(dian)流将(jiang)通过(guo)零(ling)(ling)线(xian)构成回路(lu)，由于(yu)零(ling)(ling)线(xian)阻抗较(jiao)小，所以短路(lu)电(dian)流将(jiang)很大，它促使保护装(zhuang)置迅速动作以断开电(dian)源(yuan)，从而起到保护作用；

3、零线还是单相220V电气(qi)设备(bei)的电源回路(lu)。
