单相电表如何选择以及安装时的注意事项

Release date： View count：369

单相电度表是电度表的一种，电度表主要结构是由电压线圈、电流线圈、转盘、转轴、制动磁铁、齿轮、计度器等组成。单相电表，则一般是民用，接220V的设备。那么接下来我们一起来看看单相电表如何选择以及安装时的注意事项。

　　一、单相电表如何选择?

　　1、单相电表类型的确定

　　市面上现有的单相电表主要分类为单相电子式电表、单相预付费电表、单相多费率电表、单相电子式载波电能表等，需要在选择时确定好基本的类型需求。

　　2、单相电表电流等基本选择

　　单相电表常用的电流规格有5(60)A、10(60)A、20(80)A、在选择电表电流时，需要考虑不能低于基本电流，同时也不能高于最大额定电流。例如350W电脑、300W电视，1800W空调，400W冰箱及其它用电200W左右的家用基本用电需求，那么我们可以计算出电流=(350+300+1800+400+200)W/220V≈13.9A，考虑到未来还需增加电器，所以建议选择10(60)A电表。
