1、 本产品为两元件型，配备A、C相两只电流互感器，和两只电压互感V/V器接线，额定二流5A,额定二次电压100V，配用三相三级有功或载功电能表。

1, the product is two component type, equipped with two phase current transformers of A and C, connected with two voltage mutual inductor V/V, rated second level 5A, rated two times voltage 100V, equipped with three phase three level active or load electric energy meter.

2、 对于季节性负荷变化较大的电力用户，可选用双变比宽量限电能 计量箱，不停电可在表箱内通过改变专用互感器端子盒连接片倒换变比。

2, for the power users with large seasonal load variation, the dual variable ratio and wide capacity limited energy metering box can be selected without altering power, and the ratio of the terminals of the special transformer can be changed by changing the connection piece of the special transformer.

3、 计量表箱和组合互感器一体连接，组成连体电能 计量箱，在柱上安装使用，也可以分别安装，柱上安装发现且感器，杆下安装计量箱，中间用塑料铠装电缆连接。

3, the meter box and the combined mutual inductor are connected together to form a connected electric energy metering box. It can be installed on the column and installed separately. The column is installed and detected, and the sense organ is installed. The measuring box is installed under the bar, and the plastic armoured cable is connected in the middle.
