结构特点


      本型计量箱采用环氧树脂全封闭浇注而成。器身由两台电压互感器和两台电流互感器组成。两台电压互感器采用VV-12接线,跨接在A、B、C三相上,其铁心采用优质硅钢板卷制而成,无接缝损耗,独具良好的抗谐振性能,其中一台电压互感器增加一个二次线圈,输出用户需要的220V或110V操作电源。


      两台电流互感器分别串接在A、C相上,其二次绕组带有抽头可得到不同的电流变化。


      该型计量箱不同于其他产品的-一个显著特点就是一次接线端子从产品上端两侧的水平方向引出,并且P1P2进出线端子中间加隔离墙,上端 加装透明防盗盖。此专利设计既方便接线又防止从一次窃电。一、二次均具有防窃电功能。


技术参数

1、额定频率50Hz;额定电压10kV;额定绝缘水平12/42/ 7 5kV;

2、一次绕组工频耐受电压42kV / lmin;二次绕组工频难受电压3kV / lmi n.
