结构特点


      本型计量箱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,独具良好的抗谐振功能。其中一台电压互感器可增加一个二次线圈,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高压瓷套两则的水平方向引出,并带有透明防盗罩,此专利设计方式既方便接线又防止从一次窃电,二次也有防盗盖,- - .、二次均具有防窃电功能。该产品为全密封接构,其一端安装有耐老化能伸缩的专用胶囊,隔绝变压器油与空气的接触,有效防止油的老化。
