Anti-electric theft combination transformer

Product overview

The measuring box of this type of combined transformer is fully enclosed structure of epoxy resin pouring, made of advanced materials and technology, suitable for measuring current, voltage and electric energy in outdoor power lines with 50Hz ac and rated voltage of 10kV or below. This product conforms to the provisions of gb1207-2006 electromagnetic voltage transformer, gb1208-2006 current transformer and GBI7201 combined transformer.

Conditions of use

1. Temperature range: -25c --+40C

2.  altitude: not more than 1000m.

  3. The installation site shall be free of pollution, erosion and explosive media that seriously affect the insulation of products.

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zhuanli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。
