结构特点
本型计量箱由两台电压互感器和三台电流互感器组成,采用户外环氧树脂浇注。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。两台电压互感器各有计量绕组和保护绕组。其中一台电压互感器还多增加一个二次绕组,输出用户需要的220V或110V操作电源。
三台电流互感器- - 次绕组分别串接在A、B. C三相上,其二次绕组设有计量和保护两个绕组,计量绕组带有抽头可得到不同的电流变化。保护绕组可提供线路过流或短路信号,实现真空短路器的电动分合闸、重合闸。
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套伞两侧的水平方向引出,并带有透明防盗罩,此zhuanli设计既方便接线又防止从一次窃电,二次也有防盗盖,一、二次均具有防窃电功能。
